OS speed sounds like it fits the bill at a cost, maybe the NN21R is a better option for me right now though, and any other suggestions welcomed!!
It can be easy to kill an engine, but new engines nowa days will let you know when they are too lean and anyone at the track will help you out to let you know what you need to listen for.

30% will only give you more power because you can lean the engine out a bit more with the such properties of more % of nitro the more it will cool an engine down.

25% will be ample for any Club or B Drive driver. Don't forget you've got to pay for your engines.

Regards Tuning an engine.

You get your top end right first before you do the bottom end, that's to have a fair mist of smoke coming out upto top revs.

Your bottom end needs to be tuned so when you come off of full throttle. You are back on tick over right away, no waiting 6 seconds. If you need it rich then make it take 1 second to come down to true tick over.

Do not run your engine rich. This does the same amount of damage as a lean engine. It is a myth that a rich engine will last you years, you ware the liner out with the compressed fuel being forced between the piston and liner before its ignited.
