- The Simitar style airplanes are fairly popular. They are designed by Evans and
- have appeared in RCM from time to time. The plans are available from RCM. I
- have one of the older original Simitars with a OS 25SFR. The original plans were
- for a 15 so I increased the size 10%. The wing span is 56 inches. It looks
- huge, but actually it flys fairly fast and floats in for a landing. These
- airplanes fly very well. It is actually one of the best flying that I have
- owned. It takes a little getting used to visually in that at first it is easy
- to lose track of whether it is coming or going. This is because of the lack of a
- tail.
-
- There are several of these things flying around Austin, especially at the
- Georgetown field. One version there is over 80 inches to qualify it for "Big
- Bird" status. Construction is real easy. I cut my own foam wing then sheeted
- the leading and trailing edges, applied cap strips and then used a Weller
- soldering gun to cut out the foam between the cap strips. The fuse is a box type
- construction with a very large vertical stab. The hardest part of the whole deal
- is making the template for cutting the foam wing. Which is why myself and two
- others here in Austin decided to mass produce a bunch of wings and fuse's and
- servo trays for a wing that we call "Bird of Prey".
-
- A couple of issues ago, RCM had an article on the Combat Gremlin. I have also
- built two of these. See my previous append. We have actually modified the
- design and are making kits of these things in an attempt to get a lot of them in
- the air here so that we can get some events going. They are made of foam wings
- and plastic down spout fuse's. They have a symmetrical wing with no dihedral and
- are therefore hotter than the Simitar. But any one that can fly with out
- assistance can fly one of these because they fly very well. They have no landing
- gear, so you hand launch them. I just hold above the wing and give it an
- under hand launch at about 15 degrees. The feeling is that it just sort of flies
- out of your hand. The throttle is set so that if you pull the trim back the
- motor quits. So to land I pull the the trim back before chopping the throttle
- and when I'm at about 10 feet close the throttle and belly land. No go arounds
- once you commit!
-
- I am really excited about these little planes. They are super inexpensive and
- fun to fly. If you crash one there are no tears. Just rebuild and in an evening
- and go. I had thought of having a spare wing and carring that around, but
- they're so easy to build you might as well just have a whole spare plane.
-
- Happy New Year
- Hope this sloppy weather lets up this weekend so I can fly!
