Pro 28
This is a Thunder tiger engine. That in itself says reliability and easy tune. As for is it good enough? I'm the one with the RB TM928 on mine. It is a totally new animal. If you can control it the speed is unbelievable. Is it better? Yes, If you can drive it. No, If your not smooth with a controller " novice" I would highly recommend the stock engine. Plus you can get them for under $100.00.
Hope this helps
