I know the Hyde mount sounds expensive, but in the grand scheme of things it is not. It is that much better. The wear and tear it will save on your airframe over the life of the plane will easily pay for itself. When all is said and done, you will have close 2000USD in your plane..the 100USD difference for the Hyde mount is not a large investment in the grand scheme of things. Two places you do not want to try to save money in pattern are your engine mount, especially since you are flying YS and your servos. The YS can put a lot of stress on your airframe. The YS 1.40DZ should work fine for the Twister. Not as much power as the 1.60DZ or 1.70DZ, but still should be adequate. You will be very happy in the long run if you just get the Hyde mount,
