It was a revolution in that it snapped together from black plastic parts. From what I remember it was either designed for, or supplied with a HB 25 heli engine.

Have you tried E-mailing Graupner?

Well, on their homepage they say they donīt answer on email, so...

I am looking for the right kind of petrol to use with this model. I have tried with 10% and 5% nitro but it seems to be to much. How about 1%?

You don't seriously want to start that thing. The ABS was brittle even back then - it must be much worse now. I have flown mine for about half a year, completed the bubble canopy and the finish, and sold it to somebody as display model. That thing was terrible to fly, especially when it was warm. Jurgen

Sorry, I don't have any Heli experience, but judging how long it took experienced model pilots to start flying helis then, compared to the one week that it seems to take people to pass our A test now, I can understand Jurgen's comments on flying this one.

I know that people did need replacemant parts then, but the plastic should only have become more brittle if it has been exposed to sunlight.

European engines are generally designed to run on low or no nitro fuel (0 to 5% being normal, my Irvine and OS get 0%) so I would be very happy to try the engine on straight fuel.

Perhaps Jurgen is also right about it being a nice display model?

Good luck with whatever you decide, John

Graupner Bell 47G

Old thread but do you still have the Graupner Bell and would you be looking to part with it.
