I just recently purchased a Carl Goldberg Bucker Yungmann kit. This is an old kit and was wondering if anyone has any knowledge of this kit, do's and don'ts, color schemes, etc.? I am planning on powering it with a gas motor. Possibly a 26 to 32 cc. Found some articles on the forum back in 2004 on the Jungmiester 33%, but nothing on the Jungmann kit. This is shown as a single seater with a canopy.
Any and all help on this would be most appreciated.

Thanks, Joe

This is from memory but I think your engine choices will shake that plane apart. I think it was designed for a .60 but a .90 2 stroke or a 1.2 4 stroke would be the biggest I would consider. It is a very lightly built plane but a great flying one. There are many military and civilian paint jobs out there.

Thanks for the reply. This is a IMAA or IMAC kit and it states on the box for power ( .91 to 1.50) four stroke. This is why I was considering a 26cc gas motor. I have checked further and am finding nothing on this model. Even did a search under reviews, etc. I was also surprised that this was a single seat version with enclosed canopy. All the pictures I found on the internet on the real plane, show a two seater. Does anyone else have any further info on this plane?

Again, thanks for your feed back. I have not built a kit in some years and am wanting to start this project the first of the year.

I get the feeling that the reason you were advised not to consider the engine you had in mind wasn't because of the size of the engine, but rather because of greater vibration from the gas engine. Note that TFF said he thought the engine might shake the plane apart. In the days when that kit was being sold, gas engines were not in use like they are today. He also says the plane is lightly built.

Just my $.02 worth.

Thanks Laird, you bring up a good point. Since I have posted on this, found a thread back in '03 that talks of the CG kit and the powerplants several builders suggested. Most seemed to favor the 150 to 180 size engine. All agreed that this was one impressive flying plane and came in around the 10.5 lb flying weight.

Thanks,

ps: That photo of an Edge 540, is the new Seagull ARF from Hangar 9. For a buck 70, this is a really nice plane. The recommended engine was between a 60 and 90. I put in a Saito 125 and it is a really sweet flyer. No bad tendency's and floats in for the landing.

I saw one of these at the field a few years back and it really is not that big of a plane. Going with more displacement may be desirable, but i think it is not a good candidate for a 26cc. Maybe look at the new small Saito gas offering if you want gas but the other saito's would be great as well I am sure. Anything from the 125 up.
Also I do not believe it is a good 3D aircraft in that the control surfaces are small. Also as far as IMAC goes, would this aircraft even be legal? I mean other than the beginner class which allows anything. Again, probably not the best candidate for competition IMAC. No doubt it is a great sport flyer though.

Thanks for the information,

Regards,

Joe
