The real problem is that the one way bearings keep breaking and they just dont last. Thought I would solve the problem by getting the motor mounts that lowered the motor so I could use my ofno starter box. Well that doesnt work either. The rear wheels hit the box plate and no matter how I put it on the box the wheel will not turn the motor. There is nothing wrong with the motor. It the poorly designed method of starting it. There is no way of putting a pull start on it for the drive belts are in the way. Most of the guys who bought one at my local hobby shop are having the same problem with the one way bearings. They told me that they have dropped PRP products for that reason. I have had this for a year and never had it on a parking lot to even see how fast it goes. Have been told they are plenty fast. Oh well Ill just put it on the shelf in the garage and bash with my savage and maybe in the future they will come out with a tiger drive or some better methods of starting it.Hi guys: Would like to hear from some fellas that own or have owned a PRP Xr80. Bought this car used on ebay.from a guy that had just broken in the engine and was getting out of R/C . I have never really had it on the ground running for any length of time due to problems starting the motor. The first starting the rod on the starting mechanisem broke and Prp sent me a new model with a one way bearing in it . Succeeded in starting the first time and tuned the motor and ran around a little to make sure it was broke in. Went to start it again and the one way bearing broke. Purchased another rod and the bearing and it broke on the second try. I then bought new motor mounts to lower motor so I could use my starter box. After several hours of adusting the box I cant get the motor to turn over. Have been in R/c for more than 10 years and have never ran into a problem such as this with any of my on road or off road vehicles. Even heated block and loosened plug and it wont turn over. I am at my wits end. Need all the help I can get. My local hobby shop stopped carrying PRP products on account of this problem.

Thanks in advance

Doug
