RE: Your views on the HPI K4.6HO engine please
I had the K4.6HO in my hellfire a few years back. Had lots of balls. I liked it but it had a few issues such as loose mid range needle. For the price there are better engines out there. After it died (after alot of abuse) i went for the LRP 28. It ripped. Finally i went to the os28 and never looked back.
