Pitts 12 15e final static tests... preflight check.

It is rainy and sleet/snowy today, and expected for the majority of this weekend, so no flying!

I decided to verify my MAS 12x6x3's balance - it was slightly out after tip painting a few weeks ago, so I re-balanced it. I ran a 100A, 4S test battery with my Watts Up meter in line for a full static test run.

WOT/full throttle yields 494W @ 39.4A. This plane REALLY pulls hard at anything above 55% throttle. Should fly great! Static cruise tests at 45% and 50% yielded ~146W @ 9.8A and 205W @ 13.8A respectively. Using these numbers, a 2800mAh 4S battery should run (to 75% cutoff) around 11 minutes at cruise, and 8-9min on more agressive flying.

Since static tests are usually higher by 10-15% in my experience on average, that's 10-12 minutes of flying per 4S battery. Pretty good - maybe 7 or so with superlative aerobatics.

Just awaiting the batteries to arrive, and then we should be good to go!! I can hardly wait!
