Jeff,

That was an amazing piece of information You had there. Bumling was constructed by Christer Gillgren from Sweden (he passed away som years ago). The model I will try to replicate that still remain intact was the plane in WC 1971 and 1973, builder and pilot/owner Göran Ridderström. The airplane shown in the picture for Göran Ridderström is notBumling (I think it isa model named Sly-Bird, another swedish pattern plane from beginning 1970th). Christer Gillgren has a Bumling standing on it's wing tip in the picture (his plane was yellow by the way).

Bumling is what we say about a (large) stone here in Sweden. Why the plane was named that could perhaps be because the kind of large fuselage - it is after all not so small and sleek as many other planes at that time. It could also be that it was on the heavy side compared to many planes from that era.

Other interesting information in that "National Identification - SE" sheet is that Christer Gillgren used a Swedish made radio control "Micronic". It was construced by civil engineer Gerhard Westerberg from Sweden but the radios wasmade in Japan (as ar as I know) and considered top of the line here in Sweden at the end of 1960th and beginning of 1970th.A picture of one Micronic 6 ch below. I know one club member in the RC club I was member in (at beginning to middle 1970th)had a Micronic 6 ch but not exactly the same gimbals as in picture below but the transmitter case was same anodized red aluminium. It had a very long antenna I remember (I flew with it a couple of times with a Graupner Cirrus sailplane that my friend let me control) and the linear servos was red and exactly same as EK-logictrol linear red servos (I know because I had a EK-logictrol myself and some if these servos). Well that was little RC history from this corner of the world.
