Default Highest revving Dubb Jett .40 engine ?


I'm thinking of building a free flight open power model and wondered if anyone here can tell me what is the highest revving Dubb Jett .40 engine suitable for vernturi (non-carb), open exhaust operation ? By highest revving I mean that revs highest at peak power, obviously.

Contact Dub Jett directly through their website. or

Most of all of his standard engines are setup to use muffler pressure to the tank. He builds to order, so I’m sure he can build an engine specific to your needs.

As far as stock engines go, I think a quarter midget .40 would be the closest you could
be, but again, you probably need a custom engine built.
