Robbe Schluter Magic Heli - Alan Coutts

Tuesday, September 15, 1998 5:43 AM

Great web page and a very useful service to the R/C Heli Community Well Done!

HELP!! I have a Robbe Schluter Magic II size 60 Heli. I have just aquired a Hughes 500 body kit for it but I have no assembly instructions. I have been in touch with Robbe but they have gone out of print on this one!

Has anyone got a spare copy of the detailed assembly instructions

Cheers

Thanks! - Chad Laricy

Thanks for taking the time to try and help me out, I really do appreciate it.

The problem all started with me trying to adjust the mixture screw because of my heli literally is covered with oil after the engine gets above an idle. I went back to the instructions like you said, to their factory settings and began again. I have reduced the oil problem slightly, but still at high engine revs, I have the same problem. But,
on the other hand, I am closer. Now after high engine revs, when I begin to bring the throttle back down, ever so slowly, just before it idles or a little before, it just cuts out! I can't seem to make the right adjustments.

I can get the engine to stay running some of the times, but I have to suffer with a couple of hours worth of cleaning off all the OIL! I can't seem to find that happy medium! I make small adjustments every time, usually only 1/8 TH turns.

I am using #8 O.S. plugs, is that ok?

Also I just thought of another thing that might help with your diagnosis! At high throttle, the engine seems to be sputtering, or hesitating.........seems to me to be to lean also, but does that mean that I have o live with the OIL problem! You can't tell that the oil problem is about to make me give up can you.

Again, thanks alot for your help, I hope I can return the favor some
day!

By the way, my name is Chad, nice to meet you!

POST REPLY

Yup, the #8 O.S. plug is great for that.

Sometimes IT IS really hard to get the engine running right but, let me try and help........

...............................{if all described below is the same as your setup then the FOURTH and FIFTH steps might be the one that really keeps your engine from shutting off}..............................

FIRST, did you look at the plug? If it's carbonized and not shiny anymore change it.

SECOND, what are your collective pitch settings? For your heli, and for beginning to learn they should be about -2 degrees(low stick), 6 degrees(mid stick), 10 degrees(top end pitch). The -2 degrees at the low end will give you a soft controlled landing to start with, and you should be able to hover the helicopter with hover pitch set at 6 degrees. Work with these pitch settings. Please.

THIRD, you said that you followed the instructions that came with the engine for carburetor setup. So now 1.>>> you should have an engine that starts up and idles O.K.. 2.>>> when you increase the throttle there should not be an excess of smoke. 3.>>> while hovering there should not be a lack of smoke. 4.>>> increasing and decreasing the throttle gently while in the hover should produce a crisp response from the helicopter (can you hover yet? If not then increasing the throttle from idle should provide a crisp response from the engine without an overly excessive amount of smoke or a tendency for the engine to shut off).

FOURTH, (this part is tough because I don't know what type of transmitter you have) IF you can;............... adjust your throttle curve so that when the throttle trim is in maximum position (all the way up) the heli's rotor speed is at or near hover rpm.

FIFTH, always fly with the throttle trim up. (you start the heli with the throttle hold switch in the ON position.

Why am I saying that you should fly with the throttle trim in this position?! Because this setup closely achieves an almost constant rotor speed which 1. reduces gyro workload 2. increases the controllability and the response rate of the helicopter, and 3. prevents the rotor from decreasing to an inefficient speed when the collective is lowered (I.e. when you lower the throttle/collective stick which is exactly where you said your engine cuts out).

If the rotor speed is kept constant throughout (as it should be) then the engine will not be overloaded at any point throughout the collective range.

See what happens ....... let me know.

I almost forgot !

IF your idle WAS NOT fine, then you can also adjust your idle by turning the needle in (leaning the low speed needle out) until the engine speed still seems to race even after the throttle has been reduced (rpm hanging).
Then richen the idle mixture very, very slowly until there is no more 'rpm hanging' AND the engine idles steadily.

Concept 60 SR - Kevin Griffiths

Saturday, August 22, 1998 4:04 AM

Hi,
I've just found your web site, Great site, I've attached some photos of me having some fun with my Concept 60 SR and Action Man :)
I live in Wolverhampton in England (Great weather :)) and I've been flying a couple of years now, and I really enjoy it, hope you like the photos, the last one is the Jet Ranger body I'm just finishing off,
Can you please help me, I've just fitted a Futaba GV1 Governor to my Heli and I don't know the proper gear ratio, I need to know it so I can input it into the Governor, I've looked in the Concept manual but it don't say, do you know I'd be very grateful if you can help me and tell me the gear ratio, thanks

Kevin Griffiths

POST REPLY

Sorry Kevin but I have found no documentation on the Concept 60 SR's gear ratio. If you need the ratio just count the teeth on the gears and figure it out yourself. Don't know how? Here's how you do it.

Drive Gear = gear on clutch bell

Counter Gear = big white gear that drives the tail

Bevel Pinion Gear = small metal gear that drives the main gear

Main Gear = gear connected to main mast

1. Count the number of teeth on all the gears.

2. Divide the number of teeth on the Counter Gear by the number of teeth on the Drive Gear (counter gr. / drive gr.) = A

3. Divide the number of teeth on the Main Gear by the number of teeth on the Bevel Pinion Gear (main gr. / bevel pinion gr.) = B

4. Multiply A by B (AxB) = C

5. The ratio C : 1 is the ratio of the ENGINE to the MAIN ROTOR. (ex. if C = 9, then ratio = 9 : 1 which means the engine turns nine (9) times for every one (1) revolution of the main rotor.

TIP: Mark one tooth of each gear so you dont lose count ;-)

RE: Field Box - Chad Laricy

Wednesday, August 05, 1998 11:22 PM

Thanks for getting back with me on that. I really liked how you had all that together in the box. I purchased a Ultratote from Tower and put it together, but I don't really like it for many reasons. I may look into building my own field box like yours, thanks again for the info.

One other question if it isn't a bother. The quick field charger, will it mess up the Rx or Tx batteries in any way? I have been told both ways, yes it will, and no it won't. Have you had any trouble with yours? I have the Accuglo power panel which I really like, and soon will have the Accu-cycle.

Thanks again for your help!
I am new at this and really loving it!

Where to buy parts - Larry Edwards

Wednesday, August 05, 1998 7:03 PM

I am new to the R/C world. I like planes but find them limiting compared to helicopters. I do not know where to go from here. My girl friend is planning on getting me a Helicopter Simulator for my computer so I can get
a slight feel for the real thing when I do get it. I would like to buy a begginers model helicopter so when I do crash I will not cry over the large sum of money that I lost. Then as I get better I'd like to change to a more
adequate helicopter. My problem again, is that I do not know where to but the items I need. For that matter, I do not even know what the price ranges are for these items. Do you know of some websites that I can look through or order from. I would appreciate the help very much.

Larry.

Field Box - Chad Laricy

Sunday, August 02, 1998 11:39 PM

If it is not to much to ask, where did you purchase your field box, or did you build it yourself using a tool box. I am very perticular with my "TOYS" and that would fit in very nicely!!!!

Nice web page, I really enjoyed all of it!!!!

If you don't mind, let me know about the box!

Thanks,
CHAD

POST REPLY

I put it together myself, using a regular tool box I bought from a art store.
Installed equipment includes:

*12 volt sealed lead acid battery (for starting and fueling and field
charging equipment)

*Hobbico Power panel (used to control electric fuel pump, and glow plug
ignition current)

*An outlet for easy connection and removal of start motor

*Electric fuel pump

*Quick field charger (for fast charging of receiver, and transmitter
batteries)

*Charging jack for 12 volt battery

*1 quart fuel service tank

The field box is equipped with all the above , and also stores all my small
tools, including pitch guage and miscellaneous nuts washers, ball links,
etc.. As well as the starter motor and extension.

Nexus vs. VR - James

Wednesday, July 29, 1998 1:00 AM

Can you tell me if it is worth the difference in investing the extra money in the VR verses the Nexus 46 and what are the major differences?

Thanks Jim

POST REPLY

First off the Nexus has a few problems, particularly in the starting system ( check out John's Kyosho Nexus Page ).

If you have not or are notexperienced these problems or you have learned how to get along with them then simply upgrading to a Nexus 46 would be your cheapest route.

On the other hand,.....

It is a lot easier to achieve a smoother and more trouble free setup with the Concept 46 VR.

>The clutch bell is double ball bearinged and runs truer around the clutch.

>The starting system is stronger, more durable, simpler and trouble free (no more broken pins and starter shafts) and less vibration

>One piece clutch (no more broken clutch screws)

>push pull servo controls on cyclic controls.

The BIGGEST difference is that the VR can be easily setup giving you a stronger and much more smother running helicopter requiring a lot less maintenance than the Nexus.

If you like fixing broken parts buy the Nexus.

If you to FLY helicopters buy the Concept VR

PS. I have both and I think the Nexus STINKS. The VR takes it's punishment and asks for more :)

Kavan Jet Ranger 60 size helicopter - Bill Diegel

Gyro and equipment - Ryan Hanthorn

Saturday, June 27, 1998 10:26 PM

Nice web page. I have question though... I have not been in Hellicopters very long. I have maintaned a hover and am working on hovering from the side. My question is that my friend set up my radio on the gyro part it has
0: 67%
1:70%
What does this mean: this is on a JR 8103 on rudder d/r.
I live in Lincoln, Ne and Love to fly... thanks for any help.

THANKS Ryan.

POST REPLY

In answer to your question, the two percentages relate to the two gyro gains that your helicopter will use in flight. Usually this is set up to be activated by your 'Flight Mode' switch.

While hovering you would need more gyro stabilization so your flight mode switch would be in (let's say) position 1. This will set your gyro gain to 70% (gyro holds tail steady more so you can concentrate on the other controls).

During forward flight you wouldn't need as much gyro stabilization (because, now there would be a lot more wind passing over the tail fins, keeping your heli aligned in its flight direction) so your flight mode switch would be in position 0. This will set your gyro gain to 67%. Setting the gyro gain lower for forward flight will also allow YOU to have greater control over the tail.

NOTES:

The gain on your gyro is like a password on your computer. The larger you make the password the harder it will be for unwanted elements to take over your computer (for the helicopter those unwanted elements would be wind gusts, and increases and decreases in main rotor torque).

BUT also, the harder it would be for you to take control as you would have to type more characters to get control of the computer (for the helicopter this would mean moving the rudder stick farther to see more of a response from the tail).

Hope this helps.

Aerial Viewing - Manish Patil

Thursday, June 25, 1998 8:09 AM

I am interested in knowing about remote controlled camera mounted on a small helicopter of about one metre in length. Please give all tec. details and cost of both, and what kind of software/hardware is reqd. with detailed pricing if I want to procure in India. Can it be used for traffic control? Can an infra-red camera be fixed on it for night surveillance? what will be the additional cost? What are other uses and accessories are available?

POST REPLY

I am not extremely knowledgeable in this area, but I do have a link on my links page that may provide you with a lot of valuable information on this subject. Check out my links page and click on the Aerocam link. They have a lot of information on aerial photography and equipment needed.

Helicopters - Netcom

Monday, June 22, 1998 8:40 PM

I have been flying r/c airplanes on and off for the past 5 years. Where would I obtain information in regards to getting started in the helicopter hobby? I would need to know what trainer is the recommended best. Motor? Radio? If you could help, that would be greatly appreciated. Thanks.

POST REPLY

Since you have been flying rc aircraft, you may know of a hobby shop in your area. From there you might be able to locate rc helicopter pilots in your local area. If there are no rc heli pilots close to you, try to review the helicopters available in the various model magazines (Rotary, Model Helicopter World, RCM). Then choose the one with the features that you are looking for.

I recommend reading/getting Ray's Complete Helicopter Manual, it's an excellent book detailing the setup and flying of rc helicopters.

Since you are new to rc helicopters, I would suggest getting a .30 or .46 size helicopter. The cost for spare parts are lower and the flight capabilities are the same as a larger helicopter. It is true that .60 size helicopters are generally more stable because they are heavier and less affected by wind gusts, but the rc helicopter industry has developed greatly and the smaller helis are more than capable of doing everything the larger rc helis do (aside from lifting the same loads).

Currently I am flying a Concept 46VR. I can definitely recommend this as an excellent helicopter to train with, as it can be set up to perform very soft and predictable flight . It also will allow you to do all the 3D stunt maneuvers you can think of once you become a more experienced flyer. This machine has ball bearings on almost all moving parts which makes for a very smooth and long lasting helicopter as well. It is easy to setup and, once built it is a very strong/rigid machine. This heli I also recommend to you because the prices for spare parts are low as it is a medium size helicopter.

If you are concerned about cost and complexity a good radio to start with is the JR XF622 or XF642. This helicopter radio will allow you to easily fine tune your pitch and throttle curves, and will also take you from beginner to expert flight. This radio has six channels. DO NOT ATTEMPT TO TRAIN WITH AN AIRPLANE RADIO, YOUR HELICOPTER WILL NOT FUNCTION PROPERLY. You can check out my pics page for pictures of my Concept VR. You can also visit my links page to view other information related to rc helicopters. Information including setup, general flying, 3D stunt flying, aerial photography, flying clubs, flying schools and Hobby shops.
