well, they both fly!
the first one i flew was the single motor. had it balanced where i thought it should be, elevons checked good, throttled up and it immediatly wanted to nose down hard. i figured there was no way it was going to be able to overcome that but what the hey, what we got to lose? so i throttled back a little bit and gave it a toss. it dove straight towards the ground as i was trying to give up elevator, began to level just as it hit, then scooted along the ground for a few feet and then shot into the air. once in the air the thrust didn't seem to be an issue. it flew nice and calm, not fast by any means, but very stable. i was able to do loops and very slow rolls. then you try and slow it down and things get a little nasty. as i approached stall speeds it had a very bad tendency to drop the wing tip suddenly and go into a dive. a fact reinforced to me on my 1st landing. once on the ground i adjusted the CG forward a bit and gave it another try. still really weird on take-off, almost identical as the first but once in the air it was much better. the tip stalls were reduced significantly and i did not need as much up trim to keep it flying level. 2nd landing was better but it still stalled at the last moment just off the ground. flew it again later and adjusted the CG even more forward and this seemed to be the ticket. tip stalls still happen but no where near as bad and at much lower speeds. came in for a perfectly smooth belly landing with no stall. 5 min flights on a 2S-800mah came back with 7.45v remaining. may try this one on a 3S and see what happens.
the twin pusher was completely different. it had no thrust tendency and took off smooth as can be. overall it seems more nimble and a little quicker. the thrust vectoring does work but i don't think i would want that to be my only control for left and right motion. the craft was able to do loops, but i could not get it to roll. tried multiple times with diff combos of input and thrust vectoring but nothing. overall though very easy to fly. it did not seem to have the same tip stall characteristic as the other which i once again found a little weird but who knows? i was easily able to fly 5 mins on a 3S-850 LiHV and came back in @ 11.6v so still plenty of juice to extend the flight time if you want. on landing inspection of the craft showed signs of heat in the motors but ESC, and battery were cool. i think going to the 1306 motors would be a good idea for this plane. i will check the motor bolt offsets and make another pod for them if they are diff.
