WOW...i know you're only guessing but 400-500 bucks on just the conversion. maybe its just me, but like lessen said 1k for a top shelf electric ride will price this idea out of the reach of most people.
Lets think about this...
You are replacing a $150-400 nitro motor, eliminating a $60-140 Servo, No fuel, no glow plugs, no igniters, no starter boxes, no person to put you on the starter stand, and getting the reliability and longevity of a Brushless motor. Most raced nitro motors last a few months at the max, and if a mistake is made, it can blow in in one race.
Both the SS brushless systems I had I raced for a whole season in 10th scale truck and 4wd buggy, and then sold both. If Novak can keep that kind of reliability in their motors, (and the competitors will come as well) The sport will actually get cheaper, and much more novice friendly.
People don't seem to see the significance of Novak releasing this system. Novak releasing this system will lead to 1/8th scale Electric Classes, both Buggy and Truggy, the fastest growing classes in our sport.
Imagine, 1/8 scale track owners being able to locate a track anywhere they want to due to the limited noise produced by electrics, imagine 1/8 scale indoor racing,(no loss of revenue to rainy days).
For us, imagine being able to work on your car at home, AND TEST IT, no matter where you live...
An 1/8th scale brushless class will grow this sport more than probably anything else ever has.
Obviously, an 1/8th scale Nitro class will remain, and I will probably still race it occasionally as I would miss the smoke, noise, and pitting, but this will be an evolutionary change for our sport.
