Quattro yes, Flash not quite. garden "put to bed".

Today was clear skies (mostly) but with a gusty wind. Had one 7 minute flight with the quattro-really like this plane. With hacker A30-16M and 11x6 wood prop is takes in nearly 400 watts from 3s lipoly. Consecutive outside loops no problem. Still haven't gotten the axial rolls down- the nose really drops with left aileron input. Used up around 1600 of 3000mah battery in mostly half throttle 7 minute flight. Met up with the club president and we spent 1/2 hour hiking across the road to look for a fly away glider lost 3 weeks ago in contest. Then went home.
Too chicken (gusty winds) to maiden the flash. It could use a tiny amount of stabilizer alignment but still should fly ok. I measured the rpm of 12.5x6.5 aero-naut folder prop- over 6,000 rpm at about 25A current from 2 cell A123 pack -approx. 150 watts. Have saved almost 250 grams over "stock" setup: battery 150g vs. 327g, servos 32g vs 51, no l.g. 56g. Still using the futaba mrc-4a rx/esc and attack am radio.
Main garden planted in winter rye, got a 5 h.p. snowblower "gift" last saturday (8 hour drive) and tuned it up so we have a very slow idle, smooth transition and will switch to the appropriate synthetic oil.

You may want to consider trying a 3-cell 2200 mah 25-35C pack for your Quattro. They are lighter than your 3000 packs and they put out plenty of amps for unlimited vertical performance. I usually only pull 1500 to 1800 mah out of my 2200 mah packs for a "normal" 5-6 minute flight.
