Default Picco .12 + NTC3 flywheel. What collet should I use?

Actually, the flywheel is from a AE GT2 but i'm quite sure it's the same as the NTC3's flywheel. I'm trying to install a Orion Wasp Picco based engine in the truck but the collet that came with the engine doesnt fit right in the flywheel.

Can anyone help?

Try reaming out the hole on the flywheel (on the clutch shoe side) a little at a time until the collet seats in the flywheel hole better. the problem you are having is that collet won't seat deep enough into the flywheel, encountered the same problem before and it fits better after a slight modification on the flywheel, I hope this helps.

Yup I had the same problem. I reamed the fly wheel a little. But if memory serves my right I believe AE make a special collet and spacer just for picco based engines.

The picco .12 engines usually have a small diameter for crankshaft you need buy a special collet(the collet has a smaller internal diameter) that comes with lrp .12 engines,Maybe you can find on Team Associated this type of collet .

I don't think the collet is the problem, He says "the collet that came with the engine doesn't fit right in the flywheel" meaning the "FLYWHEEL" not the collet had a problem, because the collet came with the engine, then it is the correct collet.

I don't think so. I had the same problem with my picco which came with two collets and I still could not get the fly close enough to the crank case.
I can't remember the part number but AE makes a special collet and spacer for picco brand engines

yup because the flywheel is the problem, that is why you need to ream out the flywheel. by reaming out the flywheel you don't need to buy another collet, that is how I solve the problem on my RC10GT2.

Scroll to the bottom, there's your 6mm collet for AE flywheels (51525) if you don't want to things half-ass. I don't know if it is in stock, I have never ordered from them. If you get one, treat it like gold.

If you ream the flywheel out too much, you won't be able to tighten the clutch nut properly and you'll have a new paperweight. The stock picco collets are much taller than either of the AE ones (AE did have a part number for a Picco/6mm collet, but I believe it is long discontinued...I searched forever on their site with no luck).

Thanks for the help guys! And thanks for the link wagnerov.

A friend told me he used a piece of brass tubing big enough to fit over the shaft, cut a slot in one side(just like the collet), cleaned up the burrs and slid the AE collet right over the brass tubing. I think i'll try that out first.

Give it a try, that worked with my picco .12, didn't cut a slot in it though, just made sure it was a perfect fit. good luck.
