Hi guys,
My club had an auction today, and I picked up this little beast for a really fantastic price. The problem is that I don't know what it is (which is the reason for this post) but it suuuuuure looks fast. That's why I decided to post a message here.

I'ved seen this plane around before, but I just can't put my finger on it's name. The owner had no idea what it was called (he had bought it used himself, and never flew it).

The tag said that the engine should be a .15-.25 but with a 60" wingspan and a length of 30", I somehow don't think so.

First off, can anyone identify this plane?

Secondly, can someone tell me where I should locate the CG? I know that I can figure the MAC out mathmatically, but if you own one and still have the instructions, I'd appreciate it if you look it up for me... - or did this come from a magazine construction article?

My first thoughts are to put my NIB Irvine 25 in it with a high-pitched prop (I can only fit a 6-oz tank in it). There's also the possibility of a TT 40 GP in it, but that would cram the nose area too much, I think.

And I know that one of you is going to tell me to drop a Rossi-91 into it......

Can anyone help with the identification and the CG location? This plane looks like it's gonna be fun to fly...

Thanks,

Bob

Hey Bob, sorry I can't help you with an ID. I was just wondering how the auction was. I wasn't able to make it, got stuck working. Would have loved to get up there. Any great deals?

im sure the reason for the small engine size is because of the short tail on it

set ur Irvine on the engine mount, put the battery back as far as possible in the fuse and then just do a quick balance at the thickest part of the wing at the tips,

that should give you a decent ide of how well it balances, if the tail drops quick, put the 40 on it and go rip the skies up

Looks like one of those Bill Evans Scimitar things...

Hotrodkid, thanks - that's what I was going to do....

Razor - I think that you hit the nail on the head with this one... I think that the Scimitar series was published in RCM - I'll have a look up there...

I already calculated the MAC, and I'll set the initial CG at about 28% as a starting point. This plane looks like it could be a lot of fun.

I may redo the nose with a balsa cowl, faired into a spinner, once I get the initial flights out of the way.

I'll let you know what I find out at RCM..

Agreed..... looks like a Scimitar. Bill published plans on just about every concevable size of the design.

They were pretty popular at my club field back in the 70's.

The small ones all had no hear and were hand launched. The ones I recall that did have hear had trike gear.

Yup, I agree. I think this one was from the 7/98 issue of RCM, called the Simitar Advantage (it's the only tail dragger of the four that I saw). It's not an exact dupe, it's a pretty good clone, though. Bill's plans had a 64" wingspan, a foam wing, and full-span flaps. Mine has a 60" span with a built-up wing and the flaps stop about 4" from the tips, with a fixed TE for the rest of the span. Overall, it's the same.

I'm going to have fun with this one, I can tell already. I have to find that magazine article (I hope that I have the back issue) and see what he wrote about it. I've got a TT GP-42 to put into it. I think I'll take it easy until I learn how to fly it. If it's as much fun as I think it will be, I'll put in a hotter engine. Heck, I might just make a new one with one of the Selig airfoils...!

Do you recall if there were any 'tricks' to flying one? Or, setting up reflex in the ailerons? I imagine that piloting this mut be a little bit different.

Did you have one, yourself? What were your impressions? I'd appreciate any info you can give me so that my first flight isn't my last one...

The ones I built were the .15/.20 size versions - simple elevon controls. Never built the bigger ones. Nothing really special on the setup. Balance was at 25% if I recall. Flys just like any other plane...... nothing real strange to expect.

The first two of the three I built had mechancial (sliding servo tray) control mixing. Yes, it was a while ago

could it be a Polecat ? or was that a .40-46 size ?

Thanks for the hints, Bob, and Crazy-Flite, we've pretty much decided that it is, indeed, the Simitar. Can't wait for the wx to clear to see how this thing flies. I hope to have it in flyable condition by the end of the week.

Unfortunately, the wx doesn't seem to have any intention of cooperating...

You guys are going to hate me.....

I think I just tracked this down, courtesy of another thread on this Forum. My Simitar appears to be something called a Simitar Slow Motion, as published in the January 1987 issue of Model Aviation... I guess that means that this shouldn't be put into a forum on Extreme Speed Prop Planes, huh?

The airplane appears to be built for a .15-.25 engine, though it says that if you put in a 40........

Well, you have to admit... the plane LOOKS fast.....

I don't care what its called if you put enough motor in it it will be fast!
