I was a little supprised at the price. The rpm's that were given for the APC and wood props are no better than a 26cc. There are a host of good 26cc engines on the market that will produce as much power for a lot better price. As an example, the [link=http://www.rconlysite.com/gf26promo.html]CRRC 26cc[/link] can be bought for as little as $189.00 with free shipping and is probably as good as all the other engines produced in China.
