I want something powerful that holds a good tune. I am experienced with nitro engines but I have been out of the scene for about 5years and want to get your guys input on them.
For the money I think you would be happiest using the Picco P9R.
I race at Joyce Park (where you will be racing I believe) and used the OS Ver II engine. It was a good consistent engine, durable and easy to get parts...I definatly noticed it topped out on RPMs down the back straight. It did very well on the infield. I will continue to use this engine but also have rebuilt the Mega DSII that swallowed a glow plug filament.
The Mega DSII is apparently the same as the Picco P9R and I liked the way the Mega DSII ran. I think it had a little more RPM.
