The reason I am looking into this is because I am on a collegiate team designing a heavy lift RC aircraft. In this application, we are trying to make the airframe as light as possible so we will be able to squeeze as much payload weight as we can. The less the airplane weighs, the more dead weight payload we will be able to achieve. We want to do a lipo because of the considerably lower weight that they have vs. nicad or nimh.

Thanks for the link gardfield, I will check it out and contact them.
