Hi then First post here (clearly!) I'm a BMFA A cert pilot practicing for my B test. I fly almost exclusively electiric models now, mostly "40" size and above. Mostly using A123 cells, Of which I have over 2 years experience of their remarkable advantages over LiPos. (And the odd disadvantage). Biggest model is a Ripmax 88" DH88 on, you guessed it, brushless and A123's. It is way over powered, but I learned a while ago to use that throttle stick thingy. For my sins, I've been roped into being Social Secretary at Greenacres Model Aero Club in Walsall West Midlands. I also write their website Greenacres website . I'm currently busy drumming up support for our 3 20th aniversary funflys this year. Anyone and everyone is invited and they promise to be great events, weather permitting. Plenty of details and photos of previous events are on the website. If anyone does come, seek me out and make yourself known. Shameless plug over, sorry
