    Hawk mini DLG

    I have - at last! - built and flown the Hawk mini DLG I was so kindly given at the 2018 F3K Eurotour. I want to thank everyone again, I still feel a bit guilty because I choked up and couldn't talk anymore - or couldn't without bursting in to tears. I made a small alteration from the standard build and put the tail plane on top of the fuselage ' as normal'. I sanded the pylon down a little to suit the flatter shape of the underneath of the tail plane. 4 x SD100s do the movement of surfaces, a 550mAh Blade 120SR single Lipo powers them along with a Jeti R4 Rx. About 8g of lead was required to balance the model which weighs in at 145g. The Hawk mini DLG is available from Neil H at SuperFly and other places too no doubt. Servos and battery from Stan Yeo at Phoenix Model Products I followed this RCGroups build thread for guidance - https://www.rcgroups.com/forums/showthread.php?2952429-Hawk-1m-DLG-from-HQ-models-_-Nikolay-Gorban These threads have useful DLG info in them too - https://www.rcgroups.com/forums/showthread.php?1441098-Initial-programming-of-a-DLG - GT (Gerald Taylor) knows his stuff with regard to DLGs So does Reto - https://www.rcgroups.com/forums/showthread.php?2240063-Flaperon-Linkage-with-maximum-mechanical-advantage

    flyingwings.co.uk Hawk

    I was looking for a little foamie to throw in the slope to have some fun and not worry about breaking anything in crashes. I was flying a flyingwings.co.uk Slipstream 1m delta-wing so far, but motorized. The wing was mostly indestructible, but was getting a bit floppy after lots of battering. I learned flying with this thing, 'landed' it hard on a regular basis. The wing took it well, but the motor not, the motor mount kept bending over at every crash and therefore I almost never had a straight angle of thrust. And I placed the battery so that it needed a big pack to have the right CG. It became a bit of a pain to fly, and after all - who needs a motor? Anyway. I knew that the SAS Wildthing is really nice looking and robust. But the website had some issues lately and I liked the fact that I can get all the building material at flyingwings.co.uk so that is where I went in the end. I like the looks of the hawk. It's a real bird of prey with those forward swept wings. It's probably not quite as indestructible as the Wild Thing, especially the tail feather. But I feel pretty good about it so far. I have not finished the build yet, but a few things so far. I used the laminating film they sell ant flyingwings. And I'm so glad I did. It is so incredibly robust and smooth. Way way better than strapping tape. Irons on like a dream and becomes really stiff. I put three layers on the leading edge, you barely see the layers but it's bomb proof. Unfortunately the colored tapes flyingwings sells is still crap. Covering is really bad, especially on black foam. Really a shame that they always use white foam on the pictures but send you black, where no color really works on. The foam is not very dense and has pretty big pores. Not the greatest stuff really. But perhaps normal for hot wire cut foam. The cutting is not very precise, especially the foam around the fuselage has warped quite a bit and has huge gaps. And the corners are a bit crusty and need sanding down. I soaked the whole fusilage in hot glue. I like treating the surface of EPP with a film of hot glue, that makes it ultra tough. (Also adds some weight) I will probaby find that this was overkill, but it will certainly increase longevity. The laminating foil is probably way strong enough. The elevons are light balsa. Way too flexible for the job. I would prefer dense balsa or ply. Or even just good old correx with a carbon spar glued in. I can't tell you how it flies yet. I will finish the build tomorrow or so and keep you updated. But i don't think I get a chance to actually fly anytime soon... I really did not want to tape the whole wing. But this black is really not working. I might end up having no choice. Klingon bird of prey
