Reading all the reviews, it seems this kit has been revised over the years.
The kit I got has the shown foam structure.
There's a frame with about fiberglass pieces including the control horns, motor mount(s), wheels, and servo arm extensions.
I used HXT 5 gram servos
460 mAh, 3 cell
Hextronic HXM2730-1700
Weighs 10.2 ounces
I used a landing gear with real wheels from a different foamie.
Everything was assembled with epoxy, used sparingly (wanted as much rigidity as possible, everywhere).
There's very little coupling on any axis. Perhaps due to the excessive power, I had to mix in a bit of right rudder with power application.
The elevator goes dead when in a power off dive. But, about 15% throttle is enough to reactivate it.
Plane come off the ground well (asphalt parking lot) and the rudder without a steerable tailwheel is fine.
My only real complaint is that the fiberglass motor mount system shredded immediately with full power.
I easily trued up the front of the foam bits and used a 1/16th" plywood in it's place.
