Weight :
With the saito 100, mine weighs 7 lb even. This is without the belly pan or wheel pants and with servos that weigh 0.8 oz each. (JR DS368's).


Yaw/right thrust :
I also have left yaw with throttle application problems. The instructions say there's right thrust built into the kit. There's not. I shimmed in 1.5 degrees (shim thickness 0.05") and it's not nearly enough. Hovering requires 50% high rate right rudder to keep from falling off to the right, and if you stomp it at low speed it'll immediately yaw left about 30 degrees.

Waterfalls :
I saw someone saying they couldn't get this plane to waterfall well. Mine waterfalls great -- better than my 33% Edge but not as good as my 35% Extra 260. The trick is to have enough power. I have to use full throttle with the saito 100. Two clicks less and it'll start flying out of the waterfall after 270 degrees of rotation.


Knife edge :
This thing tucks to the belly like mad with rudder input. I added 15% rudder to elevator mix and I'm going to need more. I have the CG at ~6 inches back.
