Well after lots of delays...work....life....my Viper is VERY close to being ready to fly. I had the help of a BVM rep today getting the first run on my P-160. VERY cool indeed. (my first jet)
While i dont have the cockpits fitted yet, Im wondering about the CG. I'm running two Duralite 4300mhr packs and a large pack for the engine. both the flight packs are up in the nose gear area and the engine pack is at the aft bulkhead of the nose gear area. (for now) I measured the required 220mm to 250mm Cg range. Being by myself, this was tricky, but it would appear as if im in need of about 28oz of weight in the nose. Seems like a lot to me... just under 2lbs... hear others are not using any weight...

Whats all of your experiance out there? (gear down, UAT full, ECU under the aft cockpit, 3 batteries up front) What has your experiance been with factory CG location?

Out doing shows the next two weeks, so no first flight until then, but will have time to button up the small items and get the plane balanced.

Look forward to the input.

regards,

Matt
