Post by: Wiggy on June 07, 2009, 10:26:28 pm: Didn't they sort the Apex tips out on the RX8 engine? I know from when I had my old RX7 a lot of the other owners were retro fitting RX8 tips into their engines...
I'd love another, fuel wasn't too bad on it and I never had any probs with the engine....Maybe I was lucky? Until I wrapped it round 2 lamp posts.... ;D

Post by: Coyoteboy on June 08, 2009, 11:02:54 am: Something that small could spin up to ~tens of Krpms but not much more I suspect, power output of those is currently 2.5W - you could produce more power by standing in front of a wind turbine and shouting at it ;D

Theres an RX7 (1984) being given away by someone where I work, kept under covers in the drive for 2+ years but running fine last time it was used. No takers as yet.

Post by: flyingtele on June 08, 2009, 11:51:13 am: would be awesome to put say four of those little motors together into one, and use it in a very small rc car, would go nuts! ;D
