Only 3 Screws on engine backplate
Crap, I just broke in my Novarossi RX21P5T and while disassembling it, i broke one of the screw that holds the backplate! The thread is stuck in the crankcase, can anyone suggest how to get it out? Also, is it ok to run with just 3 screws securing the backplate? Thanks guys!

drill a hole in the screw and put a screw extractor in it and pull it out. if it is really stuck, heat the engine up first with a heat gun

looks somewhat similar to a tap but without the treads. you drill the hole in the screw like he said and then you tap the extractor into the hole lightly with a hammer and then you turn that as an extension of the screw. must be very very careful with both the drilling and the extracting at that small of a scale screw tho. if it was me i would just run 3 screws and rtv around the seal and just check the 3 screws frequently. but again thats just me...i dont have the patience for trying to get a screw out that small

I had a nova plus 21-5T that came with a bad set of screws in the backplate, I snaped one off and ran it with three screw for about 2 months of racing, never had a problem. Then another one snapped!! so I only had two opposite corner screws holding on the backplate, believe it or not, I ran it like that for the remainder of the season without a single issue, no seal or nothing. So I say run it . There are some weak screws out there, I wasnt cranking them down extremeley tight either, just snug then another quarter turn. Ive owned many nova's in the past and had never had an issue with broken screws untill this one, just a bad batch of screws.
