While I don't see Brushless necessarily replacing nitro, I do see this as a great way to attract new drivers to 1/8th, while minimizing cost...
This might be a perfect way to bridge the gap between electric and nitro racers. I believe it might actually attract more electric racers to try the nitro cars if nitro motor tuning/cost was eliminated from the equation.
However, with my racing electric in the winter and gas 1/8th in the summer..
I see the following "pro's" to the idea.
1. Less Maintenance - No oil from the exhaust - less dirt sticking to the car
2. No needle tuning - just plug and play power
3. No pipe turning - or pipe dents
4. No glow plugs or shims to tune based on weather
5. No fuel mileage issues that lean out and kill the motor
6. Cost - the Nitro .21's average $500 and for that, a brushless with lipo will last longer than 1 season. (no air filters, no fuel, no glow plugs, no pipes, no pipe gaskets or springs)
7. Potentially more drivers on a Sunday afternoon - more race fees collected more competition created.
I see the following "con's" to the idea.
1. Ahh... the smell of nitro in the morning!
2. The gratification of the related sound of pulling the trigger, and the exhaust note pitch..
