Hi,
I started with electrics two month ago. Best decision I have made. Could buy a second hand Synergy that had the mounting points for the hacker C50. So no decision to make about the engine. Controller Spin99. For charging the TP 1010C/210V and for packs the Kokam 4000 30C packs. In comparision to the FP5350 this packs gives some extra power. For the Duch B-level program I only need about 2500 mAh so the cpacity of 4000 is no issue. With three packs and two chargers I can fly non stop. with one charger and two packs I can do abouth 6-8 flights in a afternoon. Tried a MZ20,5*12W, PT21*14, APC 21*14 and APC 20*15. Liked the APC 20*15 best on the Hacker C50 14XL
