Ivan Taylor’s rubber powered Mig 3.

Just a short clip of Ivan Taylor’s Mig 3. This was only a trimming flight for the Mig, but the turbulent air coming through the trees wasn’t ideal. Luckily the Mig only lost a propeller blade, so Ivan will have a new one made in no time.
Prior to the Mig flight, we had been once again trimming my DH Mosquito. The first trimming session highlighted a need for additional down thrust. With this added and 2 grams of weight on the port wing tip, the flights greatly improved. Unfortunately though, the motors proved to be under powered.
We were winding the Mosquito up so I could film it with 700 turns onboard, but the port motor decided this wasn’t meant to be, and let go at 700 turns! Only superficial damage to repair though, so I’ll have that sorted soon enough.
Thanks for watching. Please do consider a like, share and subscribe if you enjoy the videos. 👍🏻

Hi, some interesting lessons from this session. Although we previously blew a motor at 900 turns one went bang at 700. Use a winding (blast) tube. Check condition of strands. Take care with winding technique. Guilty of all three!
When flying in the shelter of upwind trees once more turns are used and the model may climb higher more turbulence can be expected. An hour after we packed up it went flat calm with possibly 2 more hours of daylight and perfect trimming conditions. On retrieving the Mig I failed to notice a prop blade missing, always check the model before moving it, even if you are pleased to see it's OK. Apart from all this we had fun.

Definitely use a blast tube. You’ve put too much work in your mossy not to

Hi James, thanks for the comment. Originally the intention was to wind the motors outside the model in a half tube, then insert into the model. But the starboard counter rotation created problems for the Piserchio hook and how it located on the motor peg in the back. The Piserchio hook and half tube setup is what’s used on Wakefields, and I liked the idea - it’s something I may still revisit this method and have some new Piserchio hooks made to cope with counter rotating propellers.
In the mean time, I will be using a blast tube. We have upped the strands on the motor now as well for more power, so the blast tube has become a necessity. We are hopefully going to get another trimming session in very soon.
