i just got an orion wasp .26(wasted good money on it) btoke the pull-start twice and when i finally got to start it it goes full throltle every time so if any 1 could suggest a new engine that works good and a not very expesive ($300-$500) i never got to use the wasp [:@]

i'll take your wasp if you dont want it LOL

there are heaps of good $250 engines like s7 or novarossi p5 or os vspec

I would check out the Mac .21, it's on sale for $209 at atomic motorsports.

i think you have a prob other than the motor? it shouldnt be going full throttle? i think you need to look at your linkage for the throttle? it might save you some cash...

[link=http://www.nitrohouse.com/eng,_ofna_picco.htm]Check out the top one on this list.[/link]

i know you like the pico but i heard they are hard to keep a tune???

check out the OS V Spec, if its power you want then it seems to be a very good engine putting out 2.94 bhp at 28,050.There is a review on it at http://www.rcnitro.com/rn/articles/dyno_vzbvspec.asp

I haven't touched the needles for 2 months now. The tune is solid.

I also ran the wasp.26 in my k3 for awhile and hated it. It's a spin all four tires full throttle (on/off switch) engine that's uncontrollable that runs out of steam real fast. I was adjusting the needles all the time to compenaste for minor atmospheric changes. Throttle response wasn't very good no feathering the throttle with this engine. It's big and heavy. Then I got the V-Spec and .

Not very expensive at $300-$500??? Geez, what's expensive to you? [&:] But, I highly recommend the Mac .21, and even more so at the limited time offer of $209. Mine runs very well from top to bottom as well as another guy at my track who runs the modded version of the same motor. Idles very well and comes up on the pipe real quick. Great power and realiable to boot. Of course in your price range there are loads of great motors.
