I redeemed myself with Der Red Mix mark II on 12/4/10 at Plaster City flyin' an L730 on t' ground then 2 x I345 in t' air one second after t' ground L burned out. Avast, me proud beauty! Great success!! I would add that me scratch-built design rotated only once durin' t' 5550 ascent so those fins are on straight!
