My main question is has anyone set their Ultimate up with Pull Pull Rudder AND Elevator. Pull Pull Rudder isn't a big deal, I'm pretty sure I can handle that, but if anyone has done a pull pull elevator, I'm interested in thier methods or suggestions for routing the wire.

Other question is what do you guys think about running a Magnum .52 Four Stroke. I've seen alot of people showing thiers with 70 sized Frou Strokes. Performance wise I don't really need or want unlimited verticle performance. I want it to be too fast or too heavy. Just a good flying sport biplane for calm sunday afternoons.

Any help is greatly appreciated.

I had a 52 FS in mine. Not much fun to fly. Read the product review on RCU, you will see the same thing, not enough power.

Agree with SPAD_MAN, Magnum 52 is not enough grunt for the GP Ultimate.

I've built two, had a Saito 65 in the first and have an OS 46Fx in the current one. Neither was overpowered. I have a Magnum 52 in a small Great Lakes bipe and would not consider it up to hauling the Ultimate.

Can help with the pull/pull question though.

One more thing about GP Ultimate, make very sure that the top and bottom wings are in line thru the wing cord (look from the side). The rear strut comes out to low or high this can big a big problem.

I used a pull-pull on my rudder and the routing is pretty simple. Just remember to mount the rudder servo in the center of the fuselage. I didn't bother with a pull-pull on the elevator, but I did use a split rod (one for each elevator half).

For power, at a minimum I would suggest a .50 2-stroke or a .65 4-stroke. It is afterall an aerobatic plane and the kit does have a tendancy to build heavy. Mine is powered with a .61 2-stroke, and yes, it does have unlimited vertical.

This is really a fantastic flying airplane. It is fully aerobatic, but lands fairly slowly. Just keep some power on because there is a lot of drag.
