I have looked high and low and I cannot find any blueprints of a Nitro R/C engine anywhere. Reason why I am looking for one is a final project for my Machining Major. I have to build an item that can be used in the real world and I couldn't think of anything better than a Nitro engine. Anyway it has come down to two options either their is a saint out there somewhere and knows where I can find a blueprint be it in a book or a web site. If all else fails I might have to go out and buy a nitro engine and get all the dimensions from it.

Also if anyone has any suggestions to make the engine better PLMK.

What do you mean by a "Nitro engine".

If you mean one of the many sport type two stroke engines in common use today I doubt if you will find any working drawings. I do not know of any manufacturer that issues drawings to the buying public. You will probably need to find a homebuilder and try to borrow his project.

Well I was really hoping for a 8 Port On-Road Racing .21 Engine.

I have e-mailed about 14 companies so it will probably be my best bet.

Although I will probably end up buying one and getting all the dimensions off of it.

If I do that anyone know of a cheap 8 port engine.

This is kinda like asking 14 software companies for their source code. You'd be better off asking for blueprints for really old and outdated designs. Even then, good luck.

I think you're best best is to buy one and reverse engineer from it.

Yeah thanks, I got quick responses from alot of companies and all of them but one couldn't help. However one of them would sell a blueprint for around $500 and was a older model that they no longer make.

Anyway I am going to buy a engine take it apart and dimension it in Pro Engineer. So if there is anyone that would like a set of them e-mail me and I will put you in my address book and once I get done with it I will send them to you guys.

By the way I am considering deminsion everything from chasis, engine and whatever part that can be made out of steel. Although I am going to build it completly out of brass and aluminum.

It's all well and good to buy an engine and then VERY carefully measure everything in the hopes you can reproduce it. But if you don't use exactly the right materials (especially for the piston/liner) then you're going to be very disappointed when it fries itself. I'd suggest getting a more normal sports type engine with piston rings then you might have a chance at getting it to run properly.

To be honest it doesn't matter if it runs because I will never start it. Reason being I am not much of a racer, one reason is because the nearest track it 200 miles away. However I love building R/C cars (I own 13) and I thought I would use the engine as project for my maching major project.

So from there I thought a Brass engine would look good or a possibility of using lucite or a clear plastic.
