Got a Screw Loose?

Be firm with screws! Oh no it's not silicon fuel tube again, yep I'm afraid so.
A small slither of silicon fuel tube under a cowl fixing screw stops the screw scratching the paint on the cowl as well as stopping them come undone due to vibration.

Tip
After drilling the cowl fixing points, insert the screws, remove the screws, put a drop of thin cyno down the holes and allow to set before reassembling.
Fuel has a nasty habit of finding it's way into nice new balsa, the cyno protects the balsa as well as strengthening the fixing point.
