I only remember the Mauler and Corsair. As soon as I post this, somebody will remind me of others... :!

   SMURTHWAITE's AMA BIOGRAPHY by Frank Macy also mentions Skyraider, Bearcat, and an experimental Jet-styled Crusader.

I only remember ever seeing the Mauler and Corsair full body kits. I tried building the Corsair but gave up on it in the late sixties. Switched to the Sterling or Johnson Guardians which seemed to be more straight forward relative to my construction skills in 1968. Then there were the profiles.

Have had both the Mauler and Corsair kits.   Yes they were built up.   In fact I have built two of the Maulers.  The second one I made the engine upright and should have left it inverted.    All the others I remember were profile. H^^

I have the kits for the Mauler and Corsair and my old beatdown Mauler from about 69' with a g21 35 in it (needs restoring). Thought a full fuse version of Skyraider or Bearcat would get my intrest up. Saw a guy with a built up Bearcat (K&B40 rearintake) flying at the sears parking lot way back then, assumed it was a J roberts offering.

Here is a J.Roberts model you haven't seen. It is a profile F-8 Crusader powered by a Johnson 36Combat with a
 slotted "vari-speed" throttle. It was built by J. Robert Smurthway himself in the early 60's. This was a hand built prototype and never kitted. I have also seen a profile AM-1 Mauler kit that was a limited production kit. It was built like a Swift or Sabre. It had a profile fuselage the matched up with the profile drawing on the built up fuselage Mauler kit plans

Nice looking F-8 Mike.  Do you know if plans are available?

I can send you a copy of the Dumas F-8 Crusader plans if you like. The construction is unusual, and the plane is not actually build on the plans. They show the plane at exactly 1/2 full size. You could blow the outlines up to full size and go from there. If I scratch-built one I wouldn't build it with an I-beam wing. I had a construction thread on this plane about a year ago.

That would be great, I'll be happy to reimburse you of course.

I love the looks of the Dumas kit, but agree - no I-Beam, thank you.  If I recall correctly, Dumas had a similar jet-style kit with more conventonial construction.  Appealling as just a knock-around airplane.

PM sent.  Thanks!

The first version was the Crusader and the second version was the Corsair II. They just bobbed the tip off the Crusader to make the Corsair II.
I always liked their looks even though the wing was not swept like it should have been.

I believe that the Dumas Corsair had a conventional flat stab and elevator instead of the V-stabilator, and a flat wing with no anhedral. To me the Dumas Crusader always looked more like a Corsair II than a Crusader anyway because of the fuselage length.

From what I can see from the photos of the kit on ebay you are correct about the wing and tail angles. I can also see that it has the same I-beam wing construction,which I thought was a well engineered method and very strong.
I flew my Crusader for many years with a Fox 36 Carrier Special. It never broke and everything always worked.
