I spoke to Kevin yesterday and he is very interested in both variants, I have now buried the church roof into the nose so will proceed with the delta version when I get chance. Bruce, Look forward to seeing that 😎 John, I added my lower fin to give me the required total vertical area, also a bit of protection for the prop and my hand when launching over arm.

Piers Bowlan Posted March 1, 2023 Share Posted March 1, 2023 Very stylish model Richard, looking forward to the plan. What is the span? It looks like a small model that will get smaller in flight very quickly! 1 Quote Link to comment Share on other sites More sharing options...

Thanks Piers, The wingspan is roughly 800mm so it is relatively small. considering I'm used to slow flying autogyros I didn't have any issues seeing it though I am yet to push it.

Richard Harris Posted March 4, 2023 Author Share Posted March 4, 2023 The wind was a bit lighter this morning so I braved the cold and took Shifty out for its second round of testing with the CG roughly moved 6mm further forward. Alot more predictable this time, as confidence grows I am slowly exploring its flight envelop, it will slow right down yet gets a bit Shifty when you open it up. At full power I am getting some kind of hunting from the motor, I'm guessing it's a timing issue with my cheap esc, you can hear it in this edited video of the closer bits.

Andy Gates Posted March 4, 2023 Share Posted March 4, 2023 Could be the ESC is over heating. Just had this with my sons plane, ESC on the outside and now fine. Quote Link to comment Share on other sites More sharing options...
Richard Harris Posted March 5, 2023 Author Share Posted March 5, 2023 Cheers Andy, I have got plenty of cooling going through the fuselage and the esc doesn't seem to be getting. That said I will try it outside the fuz. Rich Quote Link to comment Share on other sites More sharing options...
Richard Harris Posted May 10, 2023 Author Share Posted May 10, 2023 (edited) Ive got the canard version flying really well now so have moved onto building the second version, I decided to widen the fuselage to except larger lipos and help minimise the use of church roof in the nose. A couple of snaps, the lower half of the fuselage is built first onto the main keel, the forward sheeting and hatch are lite ply and the rear balsa sheet. The lower fin slots into the front and rear formers dry and sheeted each side., it's removed after to be covered. There are only a few formers on the top, the front angled one creates the cockpit front. I will sheet each side later then add the upper spines. More tomorrow hopefully.

Richard Harris Posted May 11, 2023 Author Share Posted May 11, 2023 Today I've added the upper decking sides sanded the tops to get the required curve. On top is a laminated soft balsa spine, slotted at the rear to take the upper fin. As I have a canopy plug I can use it to make another pop bottle jobbie, I have omitted the spine around the cockpit area. The nose was laminated up with oddments of wood, it's starting to take shape now. Tomorrow I will add the rear bulkhead and get out the sanding block to round things off, then mark and cut out the cockpit appature, that's if it doesn't rain....

Richard Harris Posted May 17, 2023 Author Share Posted May 17, 2023 That's the fuselage shaped, all thats required is a fine sanding before covering. The wing made up of almost 2 sheets of 6mm balsa butt jointed together. This will be profiled next, I've added reference lines to help keep things uniform whilst I shape. 4 Quote Link to comment Share on other sites More sharing options...

MattyB Posted May 18, 2023 Share Posted May 18, 2023 Looks good. I suspect this will fly significantly better as a pure wing than with the fixed canard upfront. Quote Link to comment Share on other sites More sharing options...
Richard Harris Posted May 19, 2023 Author Share Posted May 19, 2023 Cheers guys, if it flies half as good as the canard version I will be happy. The wing has now been shaped and a suitable slot cut out in each side of the fuselage. I had to take out a slice of the central upper former so will probably tab this for the delta version. Couldn't resist putting it together and comparing it to its canard version. It's a shade under 200g as it stands which isn't too bad. Next job is to cut out and hinge the elevons, print a pilot out and make a better canopy. Rich 2 Quote Link to comment Share on other sites More sharing options...
Steve Adams Posted May 23, 2023 Share Posted May 23, 2023 (edited) They look fantastic Richard! Would there ever likely be a chance of doing The Uncanny as like maybe a plan trio with these two,or a 1.5 or 2x version as that was so cool like these? I'm making some F22 Raptors(for me and two mates)out of Correx/Corro-Plas atm as I get for free off a friend instead of cardboard as plan states. Good luck with them and still keep your terrific Giros coming 😀 👍 Edited May 23, 2023 by Steve Adams 1 Quote Link to comment Share on other sites More sharing options...
Richard Harris Posted May 24, 2023 Author Share Posted May 24, 2023 (edited) Nice Raptors Steve, they will be almost indestructible! Uncanny is a bigger canard so would kind of defeat the object of the one fuselage/two wing plans idea. However, I think the Shifty duo would scale up nicely, or down for that matter. I have been pondering over a few colour scheme ideas. I need to sort out what covering I have and go from there, it doesn't need much. A better canopy has been made and a suitable sized pilot printed, just need to colour him.

What I meant was to have the Uncanny printed in the mag at the same time on a separate sheet so effectively 1 fuselage(2 wings as above designs) then Uncanny separately so a plan trio in that aspect. Sorry I don't explain myself very well,hope I've done a better job this time. 😂🤪😎👌👍 Quote Link to comment Share on other sites More sharing options...
Richard Harris Posted June 5, 2023 Author Share Posted June 5, 2023 (edited) Probably not enough room for three drawings Steve, I will stick with the two for now. I've finally got round to throwing some covering on, I am impressed with the 4max stuff as it sticks and shrinks well very much like HK's offering. A few finishing touches to add before final assembly, then I will move on to fitting her out with the electronics .

Richard Harris Posted June 6, 2023 Author Share Posted June 6, 2023 Probably is the same covering Ron, thanks for the kind comments . As the small drone motors don't come with a mounting plate I made a small ply former which screws to the bulkhead. I have also 3d printed a like for like PLA version, I'm unsure if it is up to the job so will test this out after photos if it gets that far. There is quite a distance from the bulk head to the battery bay so the motor wires have to be extended enough so as the ESC can be plugged in easily. The wires run through a small slot to the side of the lower fin to the battery bay where the ESC will live. Rich 4 Quote Link to comment Share on other sites More sharing options...
Richard Harris Posted June 10, 2023 Author Share Posted June 10, 2023 I managed to get out this morning before the storms and maiden Shifty Delta successfully. As before I had way to much throw and it was a little nose heavy, I managed to reduce the throws on the transmitter but will do them mechanically over the next few days. Once the above were ironed out I had several flights, it eats up a lot of sky! It doesn't have the slow speed handling like the canard version but I think it's quicker. A few snaps shots from the video I took, this will be uploaded later. Pretty pleased with how it flies but I obviously need more stick time to dial it in properly.

Richard Harris Posted June 11, 2023 Author Share Posted June 11, 2023 Thanks Ron I've had to edit the video as it appears it's not the easiest thing to capture Interestingly, the footage from a single flight was 7.35 minutes and there was around 20% left in the 850mah 3s lipo, so not too bad. I may purchase a couple of 1000mah to try next time I order from George or even a small 4s as there is room. Anyway, here is parts of yesterday's flight knitted together.

MattyB Posted June 15, 2023 Share Posted June 15, 2023 (edited) That does fly really well, it certainly looks better than the canard to me in terms of overall performance. I still suspect more performance could be unlockled from that one with an elevator up-front, but if you are reflex free on the main wing I suppose there isn't much of a drag penalty until you are reaching higher AoAs.

Richard Harris Posted June 16, 2023 Author Share Posted June 16, 2023 Cheers Matty, The canard is certainly the more versatile model of the two as it really does slow down well, but I have had a lot more stick time on this one. It's trims are all neutral and the motor is pretty much inline with the wing centre, I am guessing this coupled with the extra area on the fore plane may help with the lack of reflex on the elevons. Maybe a conventional elevator could further improve things but for my requirements I am happy, I am sure others will try this if it makes it into the mag which will be interesting to see. As for the delta this does need reflex and is happiest at speed from the limited stick time I have had with it, it certainly does'nt glide as well as the canard.

Going to try some of their heat shrink covering on the Shifty's, looks pretty similar to the HK stuff, has anyone tried it? Whilst I was waiting I have transfered my scribbles into electronic plans, I may alter the wing plan form on the delta version as I'm not quite sure yet. Photos are off the screen but you can make out the generic fuselage and the rough shapes. Rich Richard, what CAD are you using for your model?
