Another problem, that I also found out the hard way, is that most electric drills of the sort used for this activity don't spin fast enough to reliably start the engine. Additionally, the Yank Eliminator isn't long enough; I was grinding rubber off the left rear tire of the RC-10 with the drill chuck.
If you're still determined to try it, I've got a like-new Yank Eliminator I'll sell you for $15 + shipping. They're up to $30 now, new.
If I hadn't gone to new HPI rides, with their excellent Roto-Start, I would taken Frost's advice regarding the starting donut. The Yank Eliminator is a good idea that works fine in certain applications; just not mine...[
