I've got a Hyper 21 8-port for sale.
http://www.rcuniverse.com/market/item.cfm?itemID=408571
has fair compression, you could get (depending on how you run it) another 1/2 - 2 gallon before it needs a pinch. For $20 you can send it to Ray A racing to get it pinched and get a few more gallons out of it.
All the internals of the engine look good, the conrod, crank, bearing, piston and sleeve look good, last time I ran it the temps where 230.
will consider all trades, or $55.00 or OBO + shipping
I will not ship first.
I run nitro only, so no electrics for trades.
PayPal or escrow (
contact me first if you want to use escrow)
