Hi Ken,

my name is Richard Biron,

i built and fly the AMR SD prototype.

I have 32 flights with it so far and it flies beautifully.

ZDZ 160 with regular JMB mufflers
2 9152 per aileron
1 Hitec 5955 per elevator
2 Hitec 5955 pull pull for rudder
1 Hitec 5945 for throttle
1 Hitec 5945 for choke

3 Duralite plus 4400 MA 2 for plane and one for ignition
Emcotec DPSI for power distribution

Plane weighs 59 pounds dry. Here are the aerobatics i do with it.

Loops, rolls, hammer, cuban 8, outside loops, 4 pints rolls, 8 points rolls, rolling circles, tail slide, spins etc.

With the 160, it flies exactly like the real one.

Hope it helps.

Richard
