It is more controlled being that I don't need to worry about traffic or running into anybody else while I am driving on the track. Ideally you would want multiple individuals to test both cars. As I stated before, I am going to run the two cars once I feel they are up to my standards. I am not going to race a hooked up 18R against a M18 that isn't working, nor would I race the M18 against the 18R if it isn't performing optimally. As I stated before, once I have the cars dialed in, I am going to begin to run them on the clock for five minutes at a time and check the times. I can also record multiple runs as well. I want to see for myself which car I can get to run faster around the track. As mentioned previously, your mileage may vary.
I will have a very good time running these two cars regardless of which is faster.
You are right, the two cars really shouldn't be compared to one another. The RC18R is much heavier than the M18. My 18R weighs 18 ounces without the body and my M18 only weighs under 12.
I am going to have fun with this. I need to start running my M18 if I am going to make it out east!
BTW, I am not upset and have really enjoyed this thread. I really love the discussions.
