Today I fired up my new pro .15, and I thought my regular trx .15 was fast. This thing has so much more power plus I have a 360 pipe on it. Sometimes I cant keep the front end on the ground!:D

yeah the stinger has alot of low end power. And wil lstand up on you very quickly. If you are jumping and racing you will want to move you batteries up front so that it will stay level.
just a tip

take 1 head shim out after break in and get a turbo plug! thats really sweet but watch your temp!

You can't use a Turbo plug in a standard engine. It would leak. Turbo plugs are tapered, and require a tapered hole.

well tell that to Traxxas, the turbo plug that my LHS sold me was made by Traxxas.

sorry my bad, ITS A HOT PLUG NOT A TURBO!

[Tazz R/C owner]

I prefer cold plugs. They will burn colder, which means you can lean out the engine more, get more performance, and longer run times. Hot plugs can be used everyday, but I only use them on cold or humid days.
If the plug is too hot, the engine may suffer from detonation, pre-ignition and high running temperatures. Detonation occurs when the fuel mixture explodes quickly rather than burns.
Using a plug that is too cold will result in a loss of acceleration and top speed and will cause poor engine idle. If the plug is much colder than it should be, you might notice an excessive raw-fuel discharge from the exhaust pipe, but don't confuse this with an excessively rich fuel mixture.

BTW, there is a turbo plug next to a regular plug...
