Had the new Madness out again today! it is great fun to fly!
I added a couple of carbon fiber braces under the counterbalances on the elevators as they were showing signs of flexing. I also braced the tail with 3mm carbon tube, not that it needs it - It wanted to add a bit of tail weight so I thought I'd make the tail a bit stronger at the same time!
The YS is going really well, I would certainly reccomend these engines to anyone!
