RE: plane for rimfire
Yeah, any of the gen 2 shockies would work well. Id go for the Yak. Once my Rebel biplane kicks the bucket, thats what Im going to do with mine, put the kit in a Yak and run wild.
Im not real impressed with the power output vs weight of the rimfire, but for under $50 bucks, if your on a budget, it's still a really nice well constructed motor. Run a 3cell to get the power out of it, if you want to save weight run a TP 430mah or so. Shorter flight times, but lots less weight.
