Well I have two of the smaller Wren 44's, the older ones (about 8 lbs of thrust), air start, but am really thinking this would be ideal for some of the newer EDF units with much more thrust. I am not familiar enough with them to be sure of what I am getting, so I will defintely be asking questions.
For instance would it be better to use the A123 or the lipo batteries? Which will weigh more? Cost comparision? I am looking at some of the Dynamax conversion packages with the Skorpion motors and Castle Creation speed controllers recommended by a friend.
