The Plain Plane (OD-17) worked out so well that I decided to add  two more simplified, beginner's kits to my product line.  Since I am home bound during recovery from my hip replacement I am catching up on several design projects and getting some long delayed kits into production.  The next beginner's kit will be the Satellite.  The photo is the prototype covered before I shrank the tissue. I've already redesigned it to make it easier to build. (The way I did the butterfly tail is beyond beginner level.)  should be reporting on flight trials next week.

The next one will be a biplane. Double Trouble.

It doesn't worry you that there is already a long established 'Satellite' model ?....in fact a range of them...

Bill,

Sorry about the delay in processing your order.  I've had five days of dealing with some unanticipated complications from my reaction to one of the anesthetics used in my recent surgery and have not been able to get to the computer in my shop.

A few more shots of the Satellite prototype in test.  Is that cute or what?

Here's a short video of the Satellite prototype flying.  The wing and tail have been revised. from the previous photos.  I'm still making revisions to the tail, and have drawn up a low wing version.  If they both fly as well I will probably produce the low wing version simply as a matter of style.

Although delayed by the holidays, the low wing version is under construction.

Got the tissue on but it's too humid, raining furiously, to shrink and Krylon it.  Will have to wait until the Black Sheep Friday session at Luther to fly it indoors and Sunday at the FAC contest to fly it outdoors.

The low wing version is ready for flight testing.  Having a little fun with the preprinted tissue.  Nose block is the same one used on the high wing prototype.  Turned out to need a little weight in the tail.  The high wing prototype had a solid balsa under rudder.  It weighs 24 grams all up with rubber and ballast. Did a 60 foot flight in the back yard which proved the trim.  First serious flying tomorrow night at Luther.  Will have to make decision which version to kit.

Despite face to face assurances and paperwork we got to the Luther gym last night and found a Parks and Rec basket ball league game in progress. I'll have to get the indoor flying with the Satellite next week at the O.F.F.C. session.  Disappointing!

I took the low wing Satellite (along with several other models) to the Sepulveda Basin this morning for some tests while the FAC contest was going on. It flew but presented a few problems.  It needed a degree more wing incidence, possibly slightly more dihedral, and I'm going to make another V tail to test it without the under rudder. By the end of the month I will know which one will be in kit.

I got it sorted out and it flies as well as the high wing version.  There is one problem, however, with the under rudder it will not ROG.  I've been told that V tails are not suitable for beginners, but I'm going to try the V tail again to get it to ROG.  The issue is to make a warp free V tail that beginners can build.  Back to the drawing board (computer). Undecided

I want to get all the beginners kits on my web site by the end of the month so that they will qualify for the current International Postal competition in the 20 inch rubber category.

The solution to the ROG problem was a shorter under rudder and more stabilizer area.  I'll try to get video of the production version next Wednesday.  Now I'll find out if anyone else wants to build one.

I thought that I had a production prototype all sorted out but it did some strange things at the O.F.F.C. Predicted Time/Spot Landing contest last Wednesday.  It flew fine in dead air but modest breezes discombobulated it.  I had to put it on the balance rig and go back to the math to make sure that it was simple for anyone to trim.  A few subtle changes (You probably would not see them in a photograph.) and now it's balancing with no ballast and flying outdoors nicely.  I will check the indoor performance at the O.F.F.C. meeting tomorrow.  If all goes well, I'll cut one more production level prototype and if it is trouble free this weekend I will have it available on my web site next week.

Here's a video of it flying. I had a good flight indoor, chasing the penny planes around the ceiling... weighs 20 grams so it made the penny plane fliers nervous, but somehow I screwed up the video. We were chased out of the gym because they were setting up for the pre-schooler's lunch (gotta love summer vacation) so I got an outdoor flight.

I trotted out to the middle of the field, maybe faster than I should have, which caused the heavy breathing.  The hard left thrust adjustment and the drag tab that I needed for the indoor flight were still on it. It was breezy and I launched a bit to far right of the wind. The model turned left, into a gust, climbed sharply, stalled and fell to the grass.  I picked it up, and with the turns remaining on the motor, simply launched it again, this time to the left of the wind, resulting in the flight you see.       https://www.youtube.com/watch?v=xk8Ypfxbtfo

The production kit will be on my web site within two weeks.
