Graupner heim mechanics
Can anyone help with parts for a graupner heim mechanics in a bell 222 fuselage! I'm in need of links for the flybat to pivot on the rotor grips!
Also what motor to use to convert to brushless!

After looking at my 222 I concluded that if I needed those links I'd most likely get a set of these from Vario:

https://www.vario-helicopter.biz/us...RAD::33870.html

Cut them in half, drill holes in each half in order to join them with a threaded rod. That way you can line the links up in the same plane as opposed to the 90 degree alignment Vario uses. You gotta get creative when keeping the vintage stuff going.

As for the motor I suggest researching Vario Skyfox conversions. The Profi mechanic used in the Heim is very similiar to the Skyfox mechanic.

Take two 2.5mm ball links and connect them with a short piece of threaded rod and you can position them anyway you want. I also have some skyfox parts in stock, depending on what you may need for those mechanics.

Wrong.. only one end is 2.5mm, the fly bar end is a much larger dia. Read and see the link in post #2.

We also found this "double link" on Robbe futura rotor.

Not easy to build this thing.

We found This big ball/link on RC cars and planes...
