I recently purchased a BobCat and am almost finished with it. I have never flown a jet and I quickly realized I probably should start with a trainer first. I could not find one I liked so I came up with my own design. I started on it several months ago. When I took it to the flying field to show a friend another club member says it looks a lot like the Facet. It is almost the same, but has a fully semetrical low wing. I have a Wren MW54 I am going to put on it.
I have attached a picture. It has a 72" wingspan and is all balsa and plywood. If there is enough interest I may try to kit it.
Any comments or suggestions are welcomed.

Looks Great! What's the wing area going to be? Do you think that there's going to be enough room for fuel? Keep me posted on your progress, after building a Super Reaper, I've got an itch to build with plywood?

It is designed around the Wren MW54. It should weigh around 12-13 lbs. I have a forty ounce tank in it right now, but it could hold a much larger tank. The fuse is around 6 1/2" wide. I will get some accurate measurements, but I would say the wing area is around 850 - 900 square inches about the same as a .60-1.20 size Extra 300, Cap 232, etc. It should be a floater. I will not have retracts but could be built with them.
I'll try and get more pictures as I progress and details of first flight.

'Sounds better all the time! My Reaper is powered by a MW54 as well and has a 40oz and a 32oz tank in it. With my timer set at 7 minutes I can do a couple of "missed" approaches and still land with "comfortable" fuel. Most of my flying was done at full power. I think that your wing area is about right. The Reaper is a REAL floater at 171/4 pounds and 1650 sq. inches.

The inlets will be on the side. I assume they will be made of ply unless someone knows of a better way. I also need some suggestions on where I might find a main gear. I would like to use plastic gear because it holds up better than aluminum.

I like the lines of the fuselage.
Personally since it is a fully symmetrical airfoil I would shoot for 1100 square inches of wing and no flaps to keep things simple.
I would also put two rudders on the elevator ends. This should give you a lot better knife edge flight and would look different from other kits.
Leave some room in the front for a video camera.
Looks good, please keep us posted

I just back from Florida Jets today and I gotta say that the Facet was the most interesting new plane I saw. I'm glad that there's more planes like it in the works. A simple plane I can carry around in my car for those quick stops at the field on the way home for a few flights. This hobby gets better everyday.

Hal,
Good looking sport jet. I'm in the process of building one similar to yours - http://www.houstonhobbies.com/jets/s...-pictorial.htm
Moved houses recently so I haven't gotten my new workshop setup just yet. Unknown brought up a good question about the inlets, I've been trying out different configurations on mine and haven't come up with anything that looks appealing to the eye. Let me know what you come up with and post some more pictures.

H. Dale,
Did you ever finish the low wing jet trainer? Did you kit it? I'm interested in just that type of plane for my P-60. I've got it in a Tamjet's F-16 right now, but the airframe is old and doesn't behave well on my current grass runway.
Thanks
Jeremy

LDS sells kits which are very similar, one straight winged, the other swept.

I'm a jet inspector in Oz & recently checked the swept wing version for a friend fitted with a Kingtech
K80 & it flew very well. It 's first flight was from grass & there was no shortage of power.
Both of these list a P-60 as a suitable engine but I have a P-60 in a BVM Sabre judging by it's performance
from grass you would have to build the JetMach light for adequate performance from grass. - John.

I've looked over the JetMach series extensively. I like them, but I also like the option of a simple flyer. No retracts to deal with, minimal brakes (required under AMA), simple, slow speed design that can utilize lower priced servos (HS645MGs come to mind). If I can't find what I'm looking for, I'll have one cut. I've drawn up a similar design to Hal's. It's sort of a cross between Hal's, Jim Fox's FoxJet, a Reaction 54, and a FoxCub. But, I'd rather just buy a kit and get to building.
