Looking for a flybarless rotorhead for my MJ2. Either a complete head or parts to convert MFS2. If you have such parts on hand let me know condition and price.

Thanks in advance!

@SpooledUp

The Diabolo head is a direct fit for the Joker.
Download the Diabolo manual from minicopter website and the MJ2 and compare the head parts.
http://minicopter.de/en/downloads

The spindle/grip bearings are the same
The spindle is the same.
The grips are actually the same except but they are now drill for 5mm drags bolts on the Diabolo. You can still use use your MJ2 grips.

You need:
main rotor hub D52
2X blade grip arms D53 and ball links
follower arm parts D65 & 593 plus screws and links 385
(see page 29 on Diabolo manual)

You will also need 2 main control rods to match the swasplate to arm grips distance.
Call or email Chuck @ Peak Aircraft for the parts

good luck with the update

Santiago & Hilliheli...

Thanks so much for the information on the FBL head options. Going to cobble the bits together and make the conversion.

Thanks!

Hi, I also have a Joker 2 that I want to convert to FBL. Do I also need the main shaft of the Diabolo? I think the standard shaft is much longer. What is the part number of the additioal rods you mentioned?

Thanks, Paul

Paul,
I believe you could use either main shaft, but more important, if you are looking for stability stay with the MJ2 shaft.
If you want more aerobatic capability, then a shorter shaft is better, but I am not certain the Diabolo shaft is a direct fit on the Joker.

Thanks Santiago. Do you know if I can use the standard rods of the Joker or do I have to purchase special ones to fit the new head?

Regards,

Paul

Paul,
I am almost certain that you will need two new rods for swash to grip control.
But since I have not done it myself, I do not know what length you will need.

Gerd may know the answer to this.

Thanks for the response. I e-mailed Gerd at minicopter.de, but haven't got an answer yet. Has anybody done this conversion, because you are very sure about the fact that the Joker 2 grips and spindle will fit the main body of the Diabolo head. Getting fitting rods will be a small problem I think.

Regards, Paul

I got a mail from Gerd and he wrote that you also need the swash of the Diabolo (reason: the glue used for holding the swash together is stronger) the dampers and the main shaft.

I also saw solutions in the past where somebody has put a V-shaped insert on both sides of the opening of the main block (the place for the flybar). It contains in a slit the rods from the linkages to the swash to keep them in a fixed position. Function is the same as the followers. I used the same trick for my Henseleit 3DNT. Fortunately I got a machined insert from somebody.

Would be nice if somebody could create these inserts using a 3D-printer.
