does anyone know where to find a CAD drawing of a rc nitro engine?
The manufacturer website is probably the best idea, but I doubt they give it out.
Are you looking for a detailed model with every part represented, with which you could make a copy of the engine? I’m sure their competitors would love to have that, and for that reason, you don’t stand much chance of getting it.
But would a single solid chunk with the right proportions work for you (e.g. to design the interface with the rest of the vehicle)?
It wouldn’t hurt to ask the manufacturer for a copy of the latter. Who knows if they would be willing to do it, but it’s not much effort for you to give them a call.
There are a engines on www.3DContentCentral.com - these can give you some guidelines.
