Howdy, and thanks! Nope, my receiver pack is an in-line five pack with a purpose built carrier top. They are much shorter than the usual AA batteries in the receiver packs I use in my gas cars and trucks, and are somewhat smaller in diameter than the typical sub C Nicads. This pack is not tiny, of course, and it may in fact be 'way too heavy for E flying purposes. It does not, however, look significantly different from some of the E-Flight packs I have seen over at the AMA area hobby shop.
I don't know if you hear much about the AMA in the UK, but it is big stuff for RC people here; I'm sure %99.9 of the people in our little burg don't know or care about it one bit, but the complex is huge and located near Muncie, Indiana just about 45 minutes from our house. They have nearly seven hundred acres, and the new headquarters building and museum look very impressive from the road. I think it opens soon.
Thanks again! Glen Priest
