I just flew mine -on a Saito 100 plus a 15x4 APC on Magnum #1 fuel.
Mine weighs exactly 7 lbs dry -
The servos are all up front and balance is spot on the recommended mark. I did quite a few equipment mods and the tail wires are simply two pieces -contineous.
Real thrust is 9 lbs
so -I have 9/7--or almost 1.3 -1 thrust.
Nothing to yell about and dead slow compared to my electric foam stuff.
But it is very nice to fly and I really like it.
