This is my hots with a sachs 3.2 on it and it flys awesome!!! My friend fly's his with a quadra 42 and it fly's great but doesn't have near the vertical as mine does.

Rob-rcu I'm looking for a cowl if you still have it

It's weight is 14 lbs dry. The vertical on this thing is simply crazy but yet it floats around like a leaf when you want it to. The plane wasn't a kit it was built from plans so I didn't have a cowl. I am looking for a cowl and I hope to find one at the Toledo show but for now I don't mind looking at the engine.

Did you build up the wing, or use a foam core?
If you were to do it again, would you stick with the 3.2, or go smaller like a 2.4?
Oh, and did you make the wing two-piece as well? Pictures?

[link=http://www.fiberglassspecialtiesinc.com/catalog.htm]Fiberglass specialties[/link] lists a cowl for this airplane at $35.

If I were to do it again I would use a lightweight 2.4 such as a Brison or a FOX. A 3.2 (50cc) is overkill for the plane. Usually you would run a 22x10 on a 50 cc engine but because of the height of the plane I'm currently running a 20x10 prop. When the weather breaks I plan on trying a 21x10. With a 40cc you would not have this problem. The wing is built up and one piece. Thanks for the link I will check them out. I will also try to snap a couple more pics aswell.

Does anyone have a construction guide and materials list for the Ultra Hots? I have a set of plans and a brief extremely poor copy of the original review in MAN magazine. Thanks for any help....Johnny
Geting back to this original question...
I have a set of plans coming from MAN. I assume I'll be missing this stuff as well.
Could someone who has built this plane send me this information? (Construction guide and materials list)
Thanks!

Got my plans today, and figure on ordering wood within a couple of days.
Can anyone provide a materials list, and save me some reverse engineering work?
(I got a copy of the construction article with the plans)
Thanks!

After much procrastination, finally got mine done and in the air.
This was my first build from plans. Outfitted as tug for sailplane aerotow.
BME 44 on KS canister. HS-5625 on aileron/elevator, HS-5945 on rudder.
Came out to about 13lb.

Nice flying airplane, but nowhere close to a modern 3D profile/funfly design.
Nevertheless, a piece of model aviation history I'm happy to have in my hangar.

Since noone else had a bill of materials, I had to make one myself.
Here is what I came up with. (Tab delimited format) Hope future builders find it useful.

Congratulations on a fine looking HOTS. Hope you enjoy it for a long time
Thanks for the material list. By the way where did you acquire the plans?

Your planes look great! If you want to build a balsa cowl for them Model Airplane News has a new book out by Faye Stilley called, "Customizing R/R Airplanes". This book has a great section devoted to building cowls out of wood. Its a great book and I thought the $19.95 U.S. that I paid for mine was well worth it.

That's a fine looking plane. I'm flying an OMP 79" Yak with a Mark 2.10 and pipe. They are nice flying machines too.

Great job on the Ultra Hots. I now use the Lanier Sitnger tailfeathers on mine when I build them. I also cut the wing to 72" for better aerobatics.

You can use a twin, you just have to build a cowl around it.
