Does any have or know of any small sized plans for the Hall Bulldog. It was built by Robert Hall and ran in 1932. It's a high mounted gull winged plane. I think it is begging to be bashed from a LS 150 "kit". A 3 view would work too!! Thanks for any help.

LAter,

Tim,

I have plans for an old Cleveland Hall Gull Wing Racer, is that the same?

Sean,

I would say it's one and the same as it raced in the 1932 Cleveland National Air Race. Here is a picture. Is it the same? What size are your plans?

Tim-

1 - Nov, 1957 "American Modeler" had 3-views of the Hall Bulldog by Walter Jefferies, Jr. I could scan this if you want - email me directly.
2 - Dec, 1988 "Scale R/C Modeler" had an article & plans for a 97" span RC model for a Sachs 3.7 engine by Don Neil.
3 - Jan, 2003 (issue #209-135) "Flying Aces Club News" had 3-views by R.S. Hirsch and plans for a 26" rubber model by Pres Bruning. You could try for a back issue from FAC-GHQ, 3301 Cindy Lane, Erie PA 16506
4 - July, 1960 "American Modeler" had plans for a 14" profile CL model (I don't have this issue)

What is the "LS 150" you mention? From Google, I gather it's a 1/2A CL racing class, but no details or photos.

Now I think this is a fine idea but in truth I think this would be in the "Stand Way Back Over There And Squint Until Your Eyes Hurt" class of scale modeling....

The Hall has beutiful elliptical wings that I don't think you're going to be able to bash from the constant chord LS plan.

Dave,

The LS 150 is a 150% sized Little Stick single channel RC'er. It 's blown up 150% on a copier. There is a number of us here that have built them. They are just neat little .049 powered planes. Do a search on this forum for LS 150.

Bruce,

I think you are right. But I think it's a really cool looking racer. I guess if I am going to do one do it right the first time.

This is the closest I could come to finding 3 views, hope it helps. Sweet looking plane. I know dumas has a 45" span model of the bulldog, and they make all parts available for sale, so you could purchase just the plans from them. Let us know how it goes!

You can get a laser-cut kit for a 24" span Bulldog from Dumas Aircraft. Go to www.dumasproducts.com and click on Airplanes and New Kits.

Hey, look what I found. The artist of this is known to make a few mistakes but generally I think you can trust the basics. The wing in the other drawing is much closer to real than the pointed ellipse of mine. The good news is that the fuselage is obvioulsy simple circular sections. The only problem is that for a 36 inch span you end up with a 5 inch cowl major diameter with about a 4 inch opening. And I wouldn't want to go much smaller due to the wing area. And if you thin the fuselage you'll quickly loose the character of the design.

I do believe that a credable semi scale version could be done. For the gull wings I would go for a slippery 1/2 to 5/8 thick wing using wide solid outlines with many ribs notched into the outline. Make it up as a blank and then carve the whole lot to shape much like a big handlaunch glider wing. A few 1/16 ply proper sized ribs would act as templates to control the shaping with very little weight penalty. I'm thinking 4 per side with one obvious one placed at the strut point.

One point, this is not going to be a model that can ROG or land properly on other than pavement or a gold green. As such you may wish to consider making the LG removable for belly operation in the real world. Or perhaps make it rubbery or hinged so that it just bends up out of the way during belly landings. Otherwise it'll be cartwheel city and the fin will take a beating.

Derek-
Here's a small scan of the Jefferies 3-view from Nov, 1957 "American Modeler" I mentioned. VERY similar to yours!

Bruce-
Who was the artist of your 3-view and where did it come from?

-Dave

BMatthews

It's out of the book "The Air Racer" by Charles Mendenhall. It's a 3view history of the more significant air racers from some of the very earliest to the 50 era Reno types. The drawings are not something I'd trust for FAI world scale competition but if I want to make a rubber scale model or do something like Tim want to do they are great references.

550 H.P. 26 ft. span...sounds like a flying coffin to me.Did anyone ever fly that thing!What was the wing loading with that big radial up front.Give the pilot a V.C. I reckon.

BMatthews

Yeah, it was probably a handful alrighty. But then most of the racing planes of the times were.

SeanT

Tim,

Sorry for the late reply, I have been travelling. The plans I have are rubber powered spanning 19 or so inches. Just sent you an email.

if that same giant scala but I buy it arf or kit planes or whatever thanks

The Dumas is 24 in (60cm) span. If you scale the plan 150% you would get 90cm. 167% would give it a span of 1m. (40 in).

$35 is a cheap price. Tower wants $45. I know you have to get it to Spain so shipping might be a pain in the wallet but you would have a plan you could work with and resell the kit if not needed

Williams Brothers has a nifty 1/32nd scale plastic kit. Their instructions include nice three views while the kit and decals would also provide lots of information for scaling to whatever size you want. If you like plastic it's quite a nice kit in its own right.

claudio ramon

good morning friend thanks for the reminder of what I want planes are planes to make me a radio controlled plane in fifth scala, sorry my English is not very good, thanks.

Hola Claudio. Escribir en EspaƱol. Vamos a traducir.

Post in English and Spanish... let us translate.

friends do not understand that I meant my apology Spanish and English translator is so not good greetings and thanks.

BMatthews

Claudio, I'm afraid that scaling up a set of small plans to a 1/5 scale structure will not work very well. The best you can use small plans for is as a guide for the shapes to draw your own set of plans to the larger size.

In doing a google for "hall bulldog plans" I found a You Tube video for a 1/4 size version. The fellow appears to be willing to sell copies of the plan. It would be far better to scale down these plans to 1/5 size and slightly reduce the wood sizes to ensure a light weight wing loading.
