Nigel R Posted December 8, 2019 Author Share Posted December 8, 2019 Had a great day last week, got a few flights in and really enjoying it. Starboard engine out on flight #1 - no drama, half throttle on the port kept her moving with little rudder correction needed. Came down for an easy landing. Bit of a non-event when it came The engine had also been reluctant to start both today and when she was maidened, and, this was the one that was a few hundred rpm down on the port engine. I assume that it was also the one that had shown signs of dying back in the air. After the engine out, a closer look revealed that the spraybar had come slightly loose and would have been leaking air, probably more when starting from cold than when hot and running, and making settings unreliable. With that fixed, I moved to a different fuel as the last gallon had run out, so was due a quick retune, just a couple of clicks, and it was away again, this time no trouble with the motors, they were singing nicely, and confidence grew with the airframe, throwing it through a more enthusiastic pattern. Lots of power to haul her through vertical eights, inverted maneuvers were all fine with engines running well throughout, in a vertical she pulled straight with no tendancy to fall off left or right, a quick dive test showed CG being fairly close to optimal. Upright snaps all good, knife edge needing a tickle more rudder, inverted snaps maybe a smidge more down elevator to get a clean start. But all in all, no major changes will be needed - so really happy with that. After that, some fast low passes to savour the beat, she moves quick at full chat. I was lucky enough to have my dad along for a few in flight shots too. Four flights went all too quick - happy pilot at home time. Quote Link to comment Share on other sites More sharing options...

Ron Gray Posted December 8, 2019 Share Posted December 8, 2019 Excellent Nigel, it really does look good. Now that you’ve got it sorted, next up, retracts! Quote Link to comment Share on other sites More sharing options...
cymaz Posted December 8, 2019 Share Posted December 8, 2019 No. Make the STM (sport twin model) into a SQM (sport quad model). Quote Link to comment Share on other sites More sharing options...
Jon H Posted December 8, 2019 Share Posted December 8, 2019 Nice work! I hope this thread helps put a lid on all the nonsense that is said about twins, especially the engine failure aspect. From the sound of it you did more or less everything right, keeping power on to maintain the speed and using the tall flappy bit at the back to keep it straight. After that it is, as you rightly say, a non event. Quote Link to comment Share on other sites More sharing options...
Nigel R Posted December 8, 2019 Author Share Posted December 8, 2019 Thank you gents Cymaz, a quad, you are a bad man! Although now you mention more engines, it strikes me that I could quite easily retrofit another motor into the front end of this airframe...

Rich too Posted December 10, 2019 Share Posted December 10, 2019 That’s great Nigel, and cracking photos Quote Link to comment Share on other sites More sharing options...
Timo Starkloff Posted December 10, 2019 Share Posted December 10, 2019 Thanks for these great pictures and congratulations for an exciting new model Concerning sound, two engines are perfect, Nigel. I saw a few four-engine ones, they don’t get that certain sound when both engines are running at the same rpms.
