Lucky find. A local built up a Honker electric powered last year and it did well. I've still got one flight worthy with Enya .19 but don't fly it very often and especially after completing a Das Box Fly Bipe, which is similar in size to the Honker but a better flier.

The Das Box Fly Bipe with a Saito .30 is a delightful flier with very good take off manners, and flight manners typical of light loading. It also has a fuel tank hatch that would be ideal for electric power. If you enjoy this size bipe and want to go electric... a Das Box Fly Bipe find would be a treasure.

Enjoy the Honker... good flier when kept light.

ps... I just weighed mine and it is 47oz and as noted previous, it flew better without the muffler and gear strut. I'd guess they weigh six oz or more. The weight of yours is cause for envy and should provide much better flight than mine.
