Is there a version of the 3DD that uses a torque tube instead of a belt? And if so where do you get one in the US? Looking at a scale application where I can set the tailrotor motor fast enough to drive a Fenestron.. But keep the main rotor at about 1300.. Thanks!

Originally you could get Joker 3DD with belt or torque tube and with single or double stage gear. Today you have to ask gerd if you want to go for special combinations.

I have Joker 3DD with torque tube and single stage gear. It is by far my favorite heli (and I also have Henseleit TDR and TRex 700E)!

The 3DD is very often used in Scale models with fenestron. And you need no complete new mechanic and can use the current one. The most are using #178, #176, #253 and a small boom part #380. Then the boom parts will be glued in the beginning of the tail section and the motor mounted on #178 will be put in the small boom and locked from besides.

Currently yes (as long as the new distributor is ready to go )

Got some of the parts ordered that I need to start work on the Fenestron.. What is Minicopter part #253? I chose this Scorpion motor for the tail. Scorpion SII-3032-690 V2 Brushless Outrunner. It should work ok, right? I couldn't find a Kontronik's Kora 15-16, apparently they are older and they don't sell them anymore.. But the kv is the same.. SO on a 6S pack I should be turning close to 10,000 rpm which is about where I want.. Also how exactly does the motor shaft connect to the torque tube? Is there a Joker 3DD manual I can download somewhere? Thanks for all the info..
