1/16 scale flywheel

[Dr1ver]

Hi I am starting a project to make a nitro boat and have Purchased a 1/16 scale (team infinity 0.05ci) nitro engine. This came without a flywheel which means I am going to have to buy or make one. The question that I am asking is if any one knows of any place in the uk where I can order one of better does anyone know the size, diameter and weight for a 1/16 flywheel or have blue prints that would help a lot. Also if there is any formula to find the diameter and weight from the power and revs of the engine that would help too.

Thanx

Is that intended as a marine engine, or is it a plane engine? On a plane the prop would be its' flywheel.
You'll need to check on the manufacturers site if there's a marine setup for it.
Is it inboard? In that case, if it's in an enclosed hull it would also need a water cooled head.

The engine is made for a 1/16 car for e.g (http://www.sportwerksrc.com/Products/Default.aspx?ProdID=SWK1400). the idea of the project that i am doing is to show that i can make a water cooler for a car or plane engine so i can be run in a marine Vehicle without over heating. the main problem is that i bought it and have a 30 day return and it can't be run with out a flywheel or something that will put a fource on the engine so it doesn't over rev.

It's not a question of over revving, but it takes the rotational inertia of the flywheel weight to push the piston through its' compression stroke.
If you can still return it, do so, and start with an engine that's designed for marine use.
If you want to stay with that engine for your project, the manufacturer of that car will have the appropriate flywheel for it since the car engines all require it.
Go to their site and check out their parts list. If they don't sell parts, they will have a link there to the sites that do.

all i need is the correct size weight and diameter and i can make one it not hard.
what i might do is look at the size of other flywheels with other modals there should be a pattern in the change in size so i should be able to work down the scale to the 0.05ci size

Go on line and locate the owner's manual for that car. Look at the exploded view of the engine and the mechanicals. It might give you the size of the flywheel. You already have the engine, so you know the shaft size.
Size and weight on the flywheel will also determine how smoothly it runs, (if it's heavy enough) and how quickly it will rev up, (if it's light enough) so I still say your best bet is to just buy the one that was designed for that engine.

that a good idea ill see if i can find it
