Working on website not available yet . Right now there are only the old designs available. All the designs are CAD so they can be scaled to whatever wingspan is required. Give me a email heads up and I can provide plans at any wing span you need.

Scale combat planes are maximum wingspan of 48" with a minimum of 40". How much are your wing cores that you have left for the Mustang and Bearcat?

All of our original designs were true 1/12 scale. The P-51 has a 37" wing span and the F8f has a 36 3/8" span. If you need them to be 40" I can rescale the plans to that but the fit of the stringers and ribs will need to be adjusted to fit the 1/8 x 1/4" stock. Not a big deal but something that will need to be addressed. I wI'll redraw them in the new scale in the future. As for the cowl and canopy parts , those will require new molding and that will take a lot of time and effort.

Sorry my computer went haywire for a bit. The wing cores for the 1/12 P-51 and F8f are $20 each.

Ok , a check of the current wingspans of our plans shows that there are 6 designs that meet the current rules of min 40" and max 48" wing span. I currently offer a Hawker Huricane @ 40", P-51D @ 40", Focke Wulf Ta-152H @47-1-2", Supermarine Spitfire @ 40-3/8", Vought F4U Corsair @ 42-1-2" and Kawasaki Ki-61 @ 45-1/8". I have plaaric parts for them as well. Radial designs have full cowls and inline designs have exhaust stacks, supercharger intakes and radiator scoops as well as clear canopies.

I just pulled the trigger on a Bearcat short-kit. I'll post my impressions when it arrives. I don't fly combat, I just like Bearcats. I have a three .15's sitting unused,so I'll probably use one of them in the Bearcat. I also have several sets of small air retracts that should work. Should make for a fun little sport plane. What size engines were normally used in these planes?

The prototype model was equipped with a MVVS .21 with stock muffler. Never put retractable gear in a Bearcat but used Robart 600 units in the Ta-152.

A friend of mine has one of the original bearcats still flying. IMO, the OS .25 FX is the perfect engine for this plane. A .15 will be marginal. And these things are too small to get caught up in flying a "scale" speed. Underpowered, can spell disaster really. Once the dust settled on scale combat, 2610 class, the .25 FX was the engine to have. Magnum has one now that is just as good for less money. He has small retracts in his. I think spring air.

This is good news as he needs a new cowling, and they were impossible to find before.

I don't have a 25FX, but I do have several 32SX's that are a drop-in replacement for a 25FX. I was thinking of using a .15 as a means of keeping the weight down. The retracts I have are only rated up to 48OZ. They are of the air up, spring down type. At least with a .32, it won't be lacking for power. I have an F-82 with a pair of 32SX's that does just fine at 9 1/2 lbs.

The fastest 1/12 scale racer we ever had was the Conquest 1 racer we flew on a OS .32 SX with a Performance Speciaties Piston and sleeve upgrade. This mod allowed the engine to run over 21000 rpm static on the ground with a APC 8.5 x 5 pylon prop. The engine pulled so hard that all you had to do is hold the aircraft by the fuse around the tail, hold the nose slightly up and let go at full throttle. Once airborne and on step, this aircraft reached speeds in excess of 200 mph!!! An absolute bullet and a ton of fun to fly. It was one of those planes that when in the air no one else's wanted to fly with because they wanted to just watch. Our club was big into warbird racing and this little hotrod was so intimidating that no one wanted to compete with it. I am going through pics now and will try to post one of the prototype aircraft.

Even at 23,000rpm, pitch speed of a 5" pitch prop is only a bit over 108mph. Little airplanes are very deceiving when it comes to speed. It sure doesn't make them any less fun, though. Here's my Screamin' Demon with a 32SX, Macs pipe and APC 8-7 prop. Static rpm is 18,000+rpm. It's in the 130mph range with GPS telemetry data. Looks like my Bearcat will get a 32SX. I've got 7 of the little jewels.

Back in the day we did not have the benefits of the tech we now have. We had to rely on the speed guns that Fred Burgdorf of APC propellers to evaluate our performance. All I know is that he was so impressed with what speeds we were obtaining he got involved and loved it!😀

Fred was a great guy and the pylon racers around here idolized him. I use his props on everything under 50cc.

I have a couple of those engines in that size, and yes, with an 8x8 getting around 18,0000, 1/4 wave pipe, it is a great set up.

So yah, I think a .32 will be just fine in the Bearcat. Back in the day, there were a lot of arguments about engine size, but when you went to contests, pretty much everyone used the OS .25. The reason why is it was so reliable. The MVVS was good, but more finicky to tune.

Airhead152, Do you still have any of the OS .26 4-stroke engines going? The ones with the car cam? I always found that to be an interesting project that I had heard about.

Airhead152, you may find this of a little interest. Just finishing up an Andersen TA152 1/5th scale. Planning to get in the maiden today. 2610 combat in Montana is what turned me on to this plane, and I always wanted a bigger one. Now I do!

Great flying plan . I built 2 for Ama scale contests and competed with it in Scale Masters. I took the Best Documentation AwArd at the Masters in Hemit California back in the day. Even got picture coverage in the mags with it. It flies extremely light. NEVER land with more than 1/3 flap. It will float forever and more than likely roll over on the nose when you touch down. I found with little flap and a fair amount of speed the airplane will be so predictable on landi

Mine is for competition as well. Plan to take it to the Nats in July. Thanks for the tips on landing. I like to test stalls up high to get a feel for what they will do when slow. I am looking forward to flying her.

As far as the OS 26 SC car engine. I put a cam and head assembly on my stock .26 FS and installed it on my Dreadnought racer and I have to say it was a lot of fun. I ran it on 50% nitro fuel and it was amazing. Very fast and could keep up with the 32 in the Bearcat. Not much on idle at 4000 rpm but at full throttle it was another scalded dog on step! I'll post pics later. Even got Brian Sanders , the owner of Dreadnought, to fly it and pose with the plane for pics. I sure do miss those days😔
