Hi,

The Impact is a great flyer in most aspect ... mine have past 200 flights and i have used it for the P-07 program. Today it is my backup for the Integral.

Like most other, i have reinforced the fuselage just to be sure, and everything have hold up just fine. In the beginning, mine was powered by OS140 RX, then i put the YS160 into it. The YS is the best/perfect powerplant for this plane and i had no issues about vibration what concern this model.

Both elev and rudd servos needed to be put into the fuselage to avoid a tail heavy situation.

Adjust the CG to a forward position and it flies really great. No issues about couplings , track or any unpredictable situations. This is important to get it right!

Good Luck and enjoy a great flyer in a high level class!
