HI,
I've a novarossi flash Pt-a which needs some maintenance . Which size of flat screwdriver do I need to open its head screws ? I assume all novarossi .12 engines use same screws.

I use one sold by Mugen. Works on all slotted head bolts. Assume that others have one as well.

4-5mm flat head is the best. Any smaller it would not have enough force, too big (5.8mm) it may not lock into the slot.

Its 5.8mm. A 4mm tip is no good you need at least 5mm.
