I don't think the problem is the motor prices....Look at it this way.....A few years back,when we were all running Kyosho spyders and and HPI's....with all the hop ups,you still had cars that cost in the 700 to 1,000 range....Today,you could buy any of the pro chassis's,run a stock OS TR,and still have a faster car than those,and be under 5 or 6 hundred with radio gear...
The track should start limiting engine prices in certain classes...Racing is a monkey-see,monkey-do reaction...people see the fastest engines,and think they need them to be fast...
If everyone were told there is a certain motor allowed,and every one ran the same basic thing,you'd all have fun,at less cost...
We ran a demo of RC cars at a BMW mini show last year....
You couln't believe the amount of fun we had...stock mini's with cv 12's........
