I powered mine with a magnum .75 2-stroke. This is a great power combo. I can hover at half throttle and really have the power to pull vertical to really do the 3D with. You will be cheating yourself with a .46. I would go with a light .61-.75 or go with a YS .63, Saito .91 or Magnum .91 4-cycle. Saito would be a lot lighter than the magnum. Both are good engines (no flames please about saying the magnum is a good engine, I have had great luck witg all mine).

I used Hitec 605 servos all around, and standard on the throttle. Watch your servo setup for the throttle, elevator, and rudder. It is tight in the fuse and I had to do some re-engineering to get everything in there and have the pull pull clear the servos. Standard servos would probably work, but these are really big surfaces...

I also put a 14 oz tank in mine. Tight fit, but worth the extra flight time. This was my first ARF and I have enjoyed it. I wrote a quick review of it in the review section here. You have to look back a couple of months though.

Rest of the construction went well. Goes together very quick with little to no effort to build it straight. You do have to re-shrink some of the covering and don't use tape on your canopy while glueing it on, it will pull the paint right off of it.

I did have problems with bending my gear on takeoff. Had the rudder/tailwheel steering way to sensitive. I did some violent S-turns and then some on takeoff and that was enough to mangle the gear. I could have bent mine back in shape and re-used them, but I had a set from an old GP .40 sized Extra 300 I used instead. This was a great choice since they are a lot stronger and have let me do my harrier landing without messing the gear up every time.

All-in-all a would say this is a good plane. Worth the money I spent on it. Good luck if you decide to get one.
