RE: Venture 60 Electric setup
Well, I'm not much of a builder, and I can't say as I have any experience with a Venture 60, but I do think I'm moderately knowledgeable on e-power systems. Based on the information for the [link=http://www.btemodels.com/venture.html]Venture 60[/link] I found in the link. I would suggest a 6s setup using [link=http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=8582]Zippy 6s batteries[/link] since they would be compact and a good fit and there are plenty of 6s motors that would be a nice weight match for the expected nose weight of the Venture.
Anyways, that's not much to go on, but I thought I'd get the conversation started and hopefully someone with direct Venture experience will chime in.
