A factoid that I picked up somewhere is that the gear retraction in a IVP shifts 69 lbs. aft 16" or increases MW by 1104 lb-in.   Does anyone have verification of this?

Hi  Bob- some other thoughts-
                                               As I moved the mains in and out, checking wheel well clearances, I started thinking about how retracting those suckers might affect CG. A lot of weight on long arms, moved aft. The nose gear as well, perhaps to a lesser extent. When I do the W&B I may try to measure both extended and retracted conditions (with suitable safeguards). In the event of a spin do you suppose extending the gear might help recovery?
 
  Speaking of which- did you install stall strips?
 
  I like your idea of the spacers and I'll install some when the time comes- I'll also move the power pack. As you say, a little weight in the rear could compensate if needed.
 
  If there's not much difference between the two styles I may use the 0/90 for the baggage floor. I cut the  gear area bulkhead from the +/-45, and that leaves enough length to cut the RH armrest. Pete Sinclair (ES-P) told me to reinforce that with 6 BID top and bottom (if I understood correctly) to reduce ballooning of the fuselage when pressurized. Did you do that? -Bill
