The main is the most used 14x25.4 you can find anywhere. But to be honest, you will not notice a thing.....

Is the crank on the AD1 the same as the AD2?

Is there any manufacturer like Ultimate Racing MXS that is using the B2101 as a base? Kind of like the FP02 is based on the OS XR-B Spec 2.

bearings are the same sizes used in AD1 and AD2 engines, and every XZB and VZB the last 15+ yrs.

Dear OS

please include a collet with your engines. It is 50 cents for you, but I just paid 10$ (inc delivery) because you are the only brad that does not include a collet with the engine. That is cheap.

cheers

while I understand your frustration, Collets are usually flywheel specific, there is no standard for the taper on the collet. I think that's their reasoning for not including one, also, the new Nova engine doesn't have one either.

Picco does, as well as a dust covers for the are and exhaust intakes.

Devil is in these little details.

Collets are specific to the flywheel used.

Collet taper angles aren't standardized, but most flywheels use the same taper angle because there's simply no reason RC companies to bother with a different flywheel taper (except for special fitments), when they can all just buy premade collets by the truckload for a fraction of a cent apiece from whatever Chinese factory has decided to specialize in making RC flywheel collets. So while collets for different flywheels may not be intentionally interchangeable, most of them are interchangeable anyway.

Yes, that is my experience. Indeed in 1:8 TT I do not know of any clutch that requires a non-standard collet.

Anyone know if the head button from the spec 1 will work on the spec 2? I just got a rebuild kit for my spec 2 and noticed the button and piston head looks sand blasted compared to my other engines where they look smooth and have a tiny bit of carbon. Guessing it sucked dirt. But I have the previous xz-b spec 1 (first os speed of the new gen) I could use the button but I don’t know if it is the same. Anyone know? I could take pictures.

It should fit, but the part numbers are different
