Better 2S batteries for smaller (~1lb.) planes...

I recently procured some 1200mAh 2S Lipos from FMT Model on eBay.

The specs are:


Output: 7.4V(2S1P)1200mAh, 20C nominal, 25C burst for 15-20s
Weight About: 58.7g
Dimensions: 55(L)*28(W)*19(H) MM

Pic below from their site. Mine came in at 56g, which runs my Super Dec BL now for over 16-17 minutes per flight on a MAS 8x6 3-blade and 1400Kv RC Timer motor (see earlier blog entries for details on that retrofit).

The new system with new batteries tops over 100W on WOT. (103W). This is easily enough to do pretty much unlimited aerobatics with this plane now, nearly double the power of the stock model power system.

I can squeeze about 20 minutes max. flight times with gentle cruise (45% throttle).

While the stock 2-blade can do this on a 800mAh battery, or nearly so, the thrust and general aircraft performance is nowhere near what I see with the 1400Kv/1200Mah 2S/20A ESC system!!! It is like night and day...

THis same system, or one similar, may be of benefit for those wishing to squeeze more out of their 15-20oz. plane. My SuperDec BL is almost 18oz. full up weight...
