Ok first of all I have to confess that this isn't a massive .12 to .30 engine upgrade. I've got an old Kyosho Quad rider with a GT12 engine and instead of trying to repair the old engine, I thought it would've been easier to replace it.
The quad without the shell
So I managed to pick up a kyosho GX12 engine of ebay for 35 quid, and even though its the same size, its newer and should hopefully run a bit better. Luckily it came with exhaust, carb, clutch etc. so all I needed to do was bolt it in, but ofc things are never that easy and I found I had to do a few adjustments.
The new(ish) engine
The engines sized up
I'll be adding more on the build soon, watch this space
