This is a model that I wasn't aware of until I searched the outerzone site for other plans by Bob Palmer. Does anyone have a picture of this model? and possibly a date for it.

I believe it's may, 1954.

According to Dave Day's info Mike:
Hi Boy 46" Goyet & Palmer MAN 8/54

This is Hi-Boy. Designed by Ted Goyet and built by Bob Palmer. Bob didn't like it because the leadouts go through the wing making them too high from fuselage center. Bob wanted leadouts out the fuselage, but Ted said "no". I would recommend fuselage leadouts, like the Rick's Boxcar.

Do a search here, there was a discussion in the Old Time forum awhile back. As I recall it was also ruled an acceptable OTS design (by PAMPA, but does not fit GSCB criteria) because it was flying before the end of 1952, even though it was not published until later.
-
The Hi-Boy is legal for OTS, by PAMPA rules. I have a set of plans signed by Bob Palmer where he wrote "before 1952". Keith Trostle sent me those plans. Yell at Keith if you want to argue about Hi-Boy being legal.

Only if the leadouts come out at the wing tip. H^^

That's what makes it a Hi Boy! This is one of those birds where the "charm" is working through the quirks of the design. I did not realize it until I recently read the article, but the original was built with a side mounted engine and cheek cowls, not inverted engine as shown on the plans. The side mount would somewhat help the vertical CG.
..and Floyd's version looks fantastic.

Great looking model, Floyd!

Here is a copy of the Palmer signed plan making the HiBoy legal for OTS. This came from Keith Trostle
I have copy of the artical signed by Bob, I'll have to scan it.
The side mounted engine should help. I started building it with the side winder engine. I'll have to finish it some day.
-
The plan shows an inverted-mounted engine, so that's what I did. I would not build a side-mount version unless there was proof that such was specifically sanctioned by Bob Palmer.
I'm not an OTS judge, but I would agree that fuselage leadouts certainly change the flying characteristics. That is not permitted.

Doc, Floyd,
Check out Allowable Modifications in the PAMPA OTS rules:

I just checked out the build and plan in the august 54 Model Airplane News, and the pictures of the finished plane show the engine side mounted with cheek cowls. The plan however, is like the one above.
After reading the build for the plane, Bob Palmer is the one that changed it to an inverted engine, and said the builder would have the option of either cheek cowls and sidemounted, or inverted. It seems the pictures were taken of Goyet's version. Palmer said the reason he changed the plan to inverted is that he like that on his Smoothie. He also said it flew well but did tighter insides than outsides because of the wing being above the CG.
-
If Palmer said that side-mounted engine was OK, that's good enough for me!

...Palmer...also said it flew well but did tighter insides than outsides because of the wing being above the CG....
One way to fix that is to move the control horn back a bit to bias the controls for more outside than inside. It might take a couple or three adjustments to find the right amount. Of course, another way is to bias the handle spacing, tho Ted and others consider this a band-aid fix.
-
Hey Kim; That is a great idea I had never thought of. I have a couple of planes that have that problem from most likely a miss alignment by me. I will have to try that one. I love simple solutions. Thanks.
-
Just got a set of plans, the Hi-Boy has jumped several places up the bucket list of builds. With the battery mounted high in the top block I think I can minimize the vert CG pain. As for turning different inside & outside - hey that is easy enough to endure. No illusions about it being a world beater, but it is always fun to fly something no one else has...

Floyd Carter has built a nice one (see above post from him). I think Tom Lay has one also.

There is a nice pix of Floyd's model near the top of this thread. Floyd's model sets the bar pretty high for High-Boy's!
BTW I have been looking over OTS plans lately, notice quite a few of the upright engine airplanes also have thrust lines clearly above the wing. Many of thse were also powered by large engines - which in 1950 also meant a TALL engine. Theres airplanes all had to be pretty "top heavy" yet they appear to have flown pretty well. Viewed from that context the High Boy is not as far out as it first seems.
