RE: Stripped thread on motor mount holes / fixable?
Hi!
The best way of mounting an engine to the Dave Brown mounts is to use the supplied metal screws!
I use them on my Q-500 racer (424) powered by a Webra .40 GT and have done for years.
Never drill trough a plastic mount if you can avoid it...makes it difficult ,nearly impossible to mount the nuts when you have a tight fuselage wraped around the engine.
