My mate has killed his hyper 7 4 port engine where is the cheapest place to replace all the internals???help needed plzz

Probably cheaper to get a new engine.

i finally got to see the big boys run today, with their $600 engines. my hyper 21 8 port looked like it was pulling a lead sled. tell your buddy to spring for a RB WS7II. that thing rips the tires off the wheels

They can be found most places for $299-$310

Famous Auction Site...$299 + $6 shipping bargainrc

You could get an OS RG .21 for around $100... they are nice engines for the money.

Thx for your replys Hes thinkin about a picco .26 anygood? or just a cheap replacement .21 for the mean time.

If he was happy with the hyper 21 8 port, He can send it back to ofna for 60$ and get a fully rebuilt one. It's cheaper then just buy the parts and doing it your self. Go to www.ofna.com and go the the message board for more information.
