weight is 12-1/2 lbs. apc (w) prop17 x 8 -, 8300 rpm.>


I just don't believe it!!! ;>))

I just did a retest on mine. I tied a string to the former in front of the spar, (no fingers this time!). clamped the engine, (Super Tigre 3000), to the firewall which is ½" further back then they call for, with prop but no propnut or spinner. I then put three servo's on the stab...still didn't balance. I then put the battery, 1100 mil, on the stab and it was just a little nose down! Weight is about 10 ½ # without wheel pants, reciever, throttle or aileron servo's, glue, spinner, extensions.
