I have ordered from Paul at rc-bearings.com numerous times and can recommend the bearings as totally fit for purpose. He also knows his stuff!!!. I have recently replaced the bearings in my ASP52s- the originals lasted 3 runs!! due to cr*p fuel. It was cheaper to buy Pauls bearings than buy the service agents chinese replacements!! Other engines with new bearings include a Moki 135, two HP40's, OS91 surpass and hopefully next week an OS20 fs. Shipping is good and if the bearings are out of stock you are kept informed. The service to date has been excellent and the savings massive!!!

(I wonder if thats enough for a discount)
