BME 102 or 100
 

I just purchased a BME 102 used, on the engine cyl. heads it says 100cc but it has head shims and the seller says it is the 102, an early 102 before they had the 102 buttons on the head. I believe the seller , but I'm not sure, also I'm thinking of using a Mejlik 26x10. I think this is the prop of choice.

My friend also has one with the "100" on the buttons. If the rest looks good, it is probably a 102.

Use a Mejzlik 27x10 or a good wood 26x10 (Menz. NX, MSC etc...).

The carbon prop is better for IMAC (provides a more consistent speed), the wood props spool up faster and are better for 3D.

The shims are the tip off. It's a 102cc. I've got one, and now, also have the new 105cc!! :D
