That is what I did on the CARF Su-27 build as well, and this one is for an older CARF MiG-29 (with Matrix air gear, not hydraulic). I think I will set it up the same as I did on the Su-27, with one electronic valve on the nose and one for the mains. It is outfit with 4mm tubing currently, but I may replace with 3mm to try and reduce the speed as long as it doesn't cost me any force (as mentioned earlier, we add restrictors all the time to accomplish this, seems the oversize airline is not needed). I'm set up now with a single air tank but have plenty of room for another and essentially no weight penalty so I will add that for peace of mind.

Good tips about the brakes too, I may set that up as well.
