i just read all 32 pages. That was an interesting read.
Here is what i gathered so far, the fuel tank might leak, the rear shock tower will most likely break and you will have to drill out the arms a little bit so the arms won't be so stiff. I still can't get over the fact the the receiver is not covered and there is almost no place to put the wires. The irony is that the fuel tank leaks where the receiver and the wires are.
The plus is that the car is agile and faster than it's older brothers. And weighs lower too. I have the RR and I have some problems with it, especially with the shock, that grounded me for 2 weeks because tower mixed up my order.
What i have learned from every car I had is that a company can redesign a car all they want but with new designs come new problems. I plan to run my RR for at least another year and most likely get the RRR, got to crawl before you can run.
