i have one on my hyper 8 rtr . its a pretty decent motor. and yes ditch the pull start and put on a sealed backplate and invest in a good starter box, <i use a ofna chrometop with the big single motor> it will runn more freely with out the pullstart and 1way bearing.another thing about the motor is it will not wake up and run good till it hits about 270-280 degrees. mine ran good and pushed out good smoke at that temp.it also likes 20% and ran like crap with 30% on my eight i have a racing motor that screams at 235-240
