I think with those YS63s your going to melt that nose lite. WOW That's a lot of power for this bird. I have a YS 53 and flew it in a 70" Tigermoth with authority.

One word of caution on this DH88. The retracts offered with this plane look great although way stronger than the structure they mount into and the offered dual struts appear to be deadly. There is no way to stop them from rotating left and right. They are attached by means of one shaft held into the retract with two Allen ( grub ) screws. Then the strut is held to the shaft by one nut and an aluminum spacer. If the nut is tightened too much it will overpower the the grub screws and pull the shaft out. The springs and the slides of the struts binds when pressure is applied. The same pressure that landing loads could cause! This plane will not be able to sustain too much impact . I'm strongly considering going with a single robart strut. Scale looks be damned. It's better in my mind than taking a chance at destroying the plane. I've still not finished mine and I have the first one that came into the Hobby People in my area.

I installed a pair of older OS 40fsr's While they won't be nearly as powerful as your 63's they should be adequate. I had them in a 60 size Super Sportster I had converted to a twin with nosewhell retracts. It was fairly fast! Sold the airframe but kept those engines!
