Hi everyone I'm a novice RC kit builder so I'm still learning the tricks and limits.

The big thing is I recently purchased a Tamiya Blitzer Beetle and am yet to build the kit. I want this build to be something special so I wanted to start the build by substitute all the self tapping screws I possibly can with hex head machine screws .

There lies my problem, I don't know if it will be good for the build or not. In my mind tapping the holes and using a finer thread would offer more surface area to grip on thus making it more durable.

So there, should I tap all the holes and use machine screws or not?
