Hello, I have a new Orion .12 CRF Wasp in an OFNA CD3. After breaking in the engine (Josh Cyrul's way), with about 3 tanks of fuel, and then running on the track for about another 6 tanks, I noticed that the top of the piston head has a small "ball like" dent. Is this supposed to be there? Has anyone had any experiences with this, or is there something wrong? I have not added any head shims from stock. I am running 30% O'Donnell fuel.

Please help! I want to run this weekend, but I don't want to make things worse, if there is actually a problem.

The small 'ball like' dent is part of the piston design. Don't worry about it, it is supposed to be there. Go run it!

mx - thanks for the reassurance. I was really getting worried after spending that much money for the motor and then within a two weeks and a small amount of fuel, having the motor die.

Happy racing!

The motor is a beast. I have to now gear it down for torque because it still is pulling for more speed at the end of the straight. That motor has so much power, it is scarey. Now, if I only could drive!

Anyone who is running this motor:
What gearing are you using?

Youd have to ask someone with a cd3 that question as the information will be irrelevant with any other chassis.

I have just ordered the WASP .12 to put in My NTC3, a new "project car". Also looking for what gears to run !!!! I was going to start with Stock, and see how she felt. Anyone have any other suggestions.

I hear she really is a BEAST !!!!!

I know that every chasis is going to be slightly different, but the number of teeth on the gears should be relatively equivalent. That is all I am really looking for. Just a general idea. You can see by my signature what gears I am running.

Chiblo - check my sig for my current gearing. The way it is set up now, it is pretty good in the infield, and it is constantly pulling all the way along the back straight. I want to gear it more for low end since that is where I lack normally in my driving skills, so maybe it will help. The motor will make up for the gearing on speed for the straight.

Tires , belts , pulleys....nope. You should go into your cd3 thread and ask this question. Same for the NTC3 guy.

Simple thought here too, gear down some so you can rev this motor out. Thats about all you need to know.
