    Greg says it makes more power than on glow, just at an RPM that most don't think of when equating small engines and earth shaking power. His website says it does 11k on a Graupner 8-4 with a 4500rpm...

    I'm running two of them, a JMGlasskraft Penetrator and a Herr P-51. The Herr is a little pokey on a 6.3-4 because the fuse is so wide, I'm hoping a Propper prop will help get it off the ground, it...

    Hi guys, long time no see!

    Norvel .074 diesel head availability

    Hey guys,

    I logged into the forum for the first time in many eons because I noticed last week that Norvel had listed a "limited" quantity of diesel conversion heads for the .074. I ordered one...

  9. Anyone ever have a Webra .09/1.5cc R/C side exhaust motor?

    I've never seen one of these before, while visiting RocketRob 2 weeks ago in San Fran he gave me three of these engines to take home.

    Are they good runners? They seem 'sturdy', which is perfect...

    A Baby Bee would suit it well if you don't want a throttle, otherwise just about any 1/2A would work well I think. I'd look at a Big-Mig .049/.061 for power and livability.

    Yep. Sure did. A 6-6 on 2-3 cells is about right.

    I'd be looking to run a 5-5 on two cells for a motor on your KV range. You can always prop up a little if the amp draw is low-going to three cells will likely be too much current.

    An .010 will go significantly faster than 40mph with the right prop on a clean airframe. I've had a lot of luck with cut-down .020 props, you want to take the 4.5-2 and cut it down to about 2.5" and...

    I haven't run my MK2's, but word I got back when they were being used at the NATs was that the Mk2 was quite a bit more powerful than the Mk1, and less fragile.

    The 5.5-2 is a lighter load that one would compare to a typical 'go-fast' prop for the TD. They were ported and timed to make power at lower rpm that made props like the 5-3 square tip viable. Prop...

    The VA .049 Mk1 makes a decent sport motor-they draw fuel well on the smaller venturi (larger one doesn't make a lot of difference in sport props) and they needle well. It will perform a little...

    Or, put another way, you want the engine to unload to the peak hp RPM number. Revving faster than that is past peak torque, meaning you could be running more pitch.

    If I might make a few suggestions, as a former manufacturer of planes like your Boomerang:


    1) get a 30mm spinner from MP Jet-that's what the airframe was intended to have on it.
