John Wagg Posted July 17, 2020 Share Posted July 17, 2020 Very nice Jeff - look forward to the flight test report. What's the covering and any chance of a close-up of the cockpit area. ? Quote Link to comment Share on other sites More sharing options...
Alve Hansson Posted July 18, 2020 Share Posted July 18, 2020 I got a FlyBoy, which was stored almost finished in a garage for 20 years. After a number of hours of work, it became the maiden today. Quite unfamiliar with three channels but it ended happily. Quote Link to comment Share on other sites More sharing options...

Alve Hansson Posted July 19, 2020 Share Posted July 19, 2020 Yes it looks like that but the wing was properly mounted. Relaxing flight on a windless evening. . Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted July 19, 2020 Share Posted July 19, 2020 Well today I was able to test fly my new model, the Rans S-9 Chaos. A scale model of the microlight stressed for full aerobatics. +9 G -6G. The model is 1/5th scale, 54" span and I am highly delighted with it, Beautifuly smooth in flightand yet very, very aerobatic on high rates. Does the smoothest takeoff and landings that I have managed in years. Our top pilotin the club loves it and one member has already decided that it will be his next project. Oh! Don't let the silencer foolyopu, that is scale but made in balsa. The model is powered by an electric motor 4-Max 3541 1070 turning a,11x 5.5 AP prop froma 3000 3S battery. Measured watts was 25 I think Quote Link to comment Share on other sites More sharing options...
Chris Walby Posted July 19, 2020 Share Posted July 19, 2020 Congratulations on the maiden Peter, one I will have to add to the build list after the GTC planned for the end of the year. Is it the photo or is it very short between wing and tail plane? Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted July 19, 2020 Share Posted July 19, 2020 Just what I like to see. A happy smiling pilot holding a gorgeous plane. Congratulations Peter on a beautiful design. Another one for everyone's to do list? Cheers Steve Edited By EarlyBird on 19/07/2020 18:55:00 Quote Link to comment Share on other sites More sharing options...
David Ashby - Moderator Posted July 19, 2020 Share Posted July 19, 2020 I like that Peter, it's nicely different. Quote Link to comment Share on other sites More sharing options...
Geoff S Posted July 19, 2020 Share Posted July 19, 2020 That's a beautiful plane, Peter. Mind you that almost goes without saying for your designs but I'll still say it . Pretty good to perform like that on 25 watts as well (I'm guessing 250 in reality) Geoff Quote Link to comment Share on other sites More sharing options...
Tim C Posted July 19, 2020 Share Posted July 19, 2020 Great job Peter, let’s hope for a plan published soon Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted July 19, 2020 Share Posted July 19, 2020 Thanks for that folks. I wasn't doing the watt meter so I just heard the chap doing it. I thinkyou are almost certainly right though. Yes, it is very short coupled but that is NO problem. 3 View on on my build blog for Rans S-9 Chaos. CG at my usual 25% chord. I will now work on the final plans and articleand then it is up to Kevin Crozier Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted July 20, 2020 Share Posted July 20, 2020 Or 25 amps maybe giving just over 300 watts? Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted July 20, 2020 Share Posted July 20, 2020 I must see but I think he must have meant 250 or something. I mighty check it myself. Quote Link to comment Share on other sites More sharing options...
Bob Bertram Posted July 20, 2020 Share Posted July 20, 2020 Very nice Peter, I reckon that there will be quite a few of those built once the plans are published. Next years mass build? Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted July 20, 2020 Share Posted July 20, 2020 Kevin CRozier is thinking of jumping this to the front of my plans Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted July 20, 2020 Share Posted July 20, 2020 I just checked what Watts my set up was producing. 376 watts which is just about perfect for the weight of model. The moral of this is "Never trust someone elses figures" Quote Link to comment Share on other sites More sharing options...

Erfolg Posted July 27, 2020 Share Posted July 27, 2020 This is not a new model in the strictest definition of new. In that the model was completed in Novemberish, the weather then intervened in delaying the first flight, immediately followed by the Corona Virus and subsequent restrictions. The first flight took place approx two weeks back. It was most fortuitous that that the grass on the field had been cut, albeit with the cut grass left to be dispersed by the sun to dry it and the wind to finish its removal. My test pilot checked out the model for control surface movements. The model placed in the centre of the field, throttle opened, the model raced across the surface with all the urgency of a racing slug, on Valium. Finally it was eased into the air, swinging left, which was arrested by the pilot. Slowly the model gained height, where a number of checks were made. Firstly response to ailerons, rudder and elevator, secondly stall characteristics. The test pilot then called for a landing, as the power was only just adequate to stay in the air. We then had a discussion, where it was decided that the model was vastly underpowered, secondly that the CG was probably a little to far forward. I decided that the initial change would be to re-battery from 3s to 4s. I would then move the CG to the mid position (by removing the nose weight) If the power was still inadequate I would re-motor. A check of the motor on 3s was showing a little over 200w pulled, on a 4s this went up to 360w (approx 1/3rd improvement). The next good day had us back at the field, a bit blowy. On attempting to arm the model, I discovered I had left the conversion plug at home. At present I am going through my collection of models and converting them from Deans to XT60 plugs, which mainly involves the ESC, in this case the ESC was done, this old, seldom used Lipo was still on Deans. This week-end was yet another good day. Back at the field the model was once more prepared and checked. This time the model raced across the field like racing Pony, on its 360w. My pilot did say, you know with a horse up front or 760w it would be a real monster. Who remembers those lectures with respect to James Watt his horse and deciding that a horse power would be 33,000 ft lb per minute? The good news is now the model takes of with authority, no tendency to swing left being on the stall. The roll rate is adequate, inverted flight good, loops good, spins reluctantly entered in both directions, stall turns fine. So + 6 months down the line the model is OK. Just about ready for me.

Graham Davies 3 Posted August 2, 2020 Share Posted August 2, 2020 Slightly previous here as it's not quite ready for maiden today, but this is my refurbed Wot's Wot. It's been in the loft of may last 3 houses, so hasn't flown for 25 years. Last flew on an ASP61, now has a nice SC91FS up front. Covered with the Richard Wills approved brown paper method, and sprayed with discontinued Halfords car paints at just £3 a can. It's going to get a bit more trim before it flies, but should be up in the air again next weekend. I think it looks OK.. Graham Quote Link to comment Share on other sites More sharing options...
