Does anyone here have experience with the '52 Stuka and the latter Ambroid/RSM Stuka?
I have one built from original '52 plans which is a pretty good flier, but have not seen, or flown, the later version.
TIA

The flying characteristics are essentially the same with minor cosmetic differences and a few updates (simplification) of construction. They are both excellent flyers. We have incorporated a few simplifications into the 52 design, all of which are perfectly legal as it maintains the outside dimensions and looks.

Thanks, Leonard.
What simplifications to the original did y'all make? I have only built a plans "direct" version. And I have only seen poor pictures of the later ('60 ??) Stuka.
The '52 built up light with no real concern with trying to keep weight down. It has pretty good flight characteristics. Using a very good '57 Fox 25 on it. Would like to know the construction changes.

I have the 'Broid model, with a Fox 29. I restored it with a green finish and yellow tail. It flies pretty well. Didn't have the original canopy, so I took a "jet" styled one, and made it look like one of the latter Stukas that had a smoother looking canopy. Used a lot of 1/16" tape to give it the "greenhouse" look of the actual plane.

The plane looks great in the air.

When I plans built mine I *cheated* and used a canopy from Dave Midgely. I believe it was the Ambriod canopy. (??) Had the framing molded in. Started to do the original canopy but I got lazy.
I used a set of streamline wheels with wood centers which I have not been able to identify.
I like mine, and might fly it in OTS and Classic at Huntersville in a couple weeks.

Speaking of pants, I cheated on mine, too. Just used some standard, '30s-looking streamlined jobs. They look fine.

The plane does build light as is, and the first one Matt has was built straight from the plans. No deviation. The next one was build with a couple of refinements, including the adjustables of tip weight box and leadouts. Instead of making the flaps and rudder of two sheets with cut outs and ribs in between, they were made solid with the same cutouts. Then the gear was changed to a removeable, Carl Goldberg style. I have never liked the J hook routine, and if (when) the gear gets bent it is hard (near impossible) to straighten it the way it was originally constructed. But (Still) that was the way it was done in those days. The canopy was just built up and hollowed out of balsa and painted, and the final change was to make a removeable and adjustable tank.

Thanks Len,
I did the tip weight box when I made mine. Didn't do the adj. leadouts, but have had no problems there (dumb luck). Some of the others I thought about, but the gear and removable tank are some that I SHOULD have thought about. Especially the tank.

>But (Still) that was the way it was done in those days.

Good one!

This may be a little off subject, but I was going through my collection of plans and came across one that is Air Trails Plan #452. In addition to a "Stuka Stunt," it has plans for a "Hall-Massey Racer." No clue who designed it or who drew the plans. It's about 500 sq/in and calls for a Fox .29. What do I have?

Hi Gary,
I have the 1952 "Hobby Helper's" plans. They are the original printing of the Still Stuka. #452. However, contrary to what Larry F. posted below, mine does have the wheel pants shown. (??)

I just finished an Ambroid Stuka Stunt. When I compared the plans from the kit to the Air Trails plans, the only obvious diference seems to be the shape of the flaps and the way they are constructed. The Air Trails plans do not show wheel pants where the Ambroid version does. I built the kit but made the flaps removeable as to swap out for the old time version. But my question here is, would I really need to swap flaps or could I get away with flying it just the way it is in Old Time? What about the wheel pants? They too are removeable, but it looks so cool with them on. No Dan, I wont take off my pants, unless I absolutly have to. By the way with the FP .20, it flies very much like my sons Skyray, light on the lines, very responsive and grooves pretty ##### good 5.0 laps with 57 foot lines. a lot of fun to fly. I give it a B+.

Larry,
My copy of the 1952 Hobby Helpers plans show wheel pants. (??) An old flying buddy of mine bought these plans in the early '50s.

I don't know what plans you are looking at, but the Air Trails plan (Old Time legal 1951 version) did have wheel pants.

As to the difference between this and the Ambroid kit, the kit was based on a later version of the Stuka (trying to be up to date at the time. Today we want to revert to the earlier version) and there were more differences besides the flap shape and construction. Check the cowl shape and location, for instance. And the canopy. There are minor "tweaks" here and there which would not make it old time legal even if you changed flaps (and are honest).

Yes, with all the flap about honesty in that other controversy, honesty is something we live by. You enter an Old Time plane and you tell the director you followed the plans. You enter a classic design and you mention that you did or did not make modifications. Unless something is obviouisly wrong, people accept our honesty. (Who brings a ruler to check to see if you increased the moments by half an inch or the size of the elevator just "slightly"?) Even in the PA events, sometimes they will check our lines. Usually they don't. We tell them what engine is under the hood for the pull test. How often have they checked? And for the weigh-in at the FAI, is it possible to take out the tip weight, the tank, and other "non essential" portions of the plane before weigh in?

Honesty is always a part of our event, and we rely on that honesty. In your case, the answer is "no" to its being legal for OT stunt, even with a change in flaps.

Thanks Len, That pretty much clears up that issue. I would'nt want to enter it in Old Time and get funny looks from everyone. Larry, NorCal Circle Jerks
