RE: brushless on Nimh
Back in the days I was doing 15-20 minute runs off GP3300 NIMHs using an LRP sensored 8.5 brushless setup. So yes it is possible, but it can be very difficult to deliver the performance the modern user demands today. With reason there is little benefit in buying more expensive packs, just get the cheapest packs you can ie. GP3300's used to be $25. If you are going to be paying $50. or $80. for the more expensive high-end NIMHs, you might as well get a decent LiPo for that cost as the best NIMH out there is still beaten by a mediocre LiPo.
