The Robart is a way better design, the frames are better material, and the pin slot is curved to follow pin motion in the trunion.

Yeah, speed brake - get all you can get. You'll need it. I powered mine with a Hitec HS-645 for reference. Worked perfectly.

If you concentrate on getting good quality elevon servos, you may never see the issues in dutch roll.

On the spec sheet posted above, I wouldn't limit myself to those max thrust specs. It can handle more. Its the residual (idle) thrust in landing what you need to worry about...

You are really making me think about fixing my old bird... Good luck!

Hehe! Yes you should.

Ok, so I will try find the robart retracts or just get the JTM ones.

To be honest I saw some slop, and I didn't like.

Elevon servos, was going on Digi Spektrum 10Kgs Metal gear...

Will mount the wren 44gold on.

Any pictures of the engine mount? Mine seems custom, and not quite as it should be....

Thanks!!!!
