Weird, you mention the single most important thing when sticking things together, clean (and dry) surfaces. A little wire brushing can help, break through any surface issues and provide a little extra surface to stick to. Letting it set for a day should help some too. Or maybe you were just unlucky and got a bad or old batch of Velcro?

I’ve had the best results (for 1/10 scale) with the clear with red backing servo tape. Seems to hold real well, has a little give to it, and strangely enough is reasonably easy to get off cleanly. Sold by Parma and 3M, probably others.


What is your RX8 in? Reason I ask, there are a lot of electric 1/8 scale buggies and truggies in my area, have been for some time. Hard mounting the speed control seems to be a significant contributor to the high rate of 1/8 speed control failures. They were noticing that the speedo frequently gave up right when the car took a hard hit.

Most of the 1/8 guys in our area are soft mounting the speedos now. Typically mounting on a block of foam, with a couple slightly loose zip ties. With a little extra length of wire. So the speedo can give some in hard hits. Velcro helps some too, not sure but I think some are using multiple layers to get a similar effect.

Hasn’t eliminated failures, but sure seems to have helped.
