RE: And another CG Ultimate Build
The 1.20AX is insane. I am on my 3rd Ultimate from GB. (there was a seagull arf in the middle) I have a 17x6 APC on it and vertical is unlimited to say the least. With a 6" pitch prop it can go wide open straight and level. I would not try it in even a slight dive. Getting the CG where I like was a little tricky. I have 2 elev servos in the tail and the battery is on a tray behind the canopy. With a ST 90 like I had on the other two, the battery was still behind the wings, but the elev servo was in the stock location. Some guys are using a 16x8 on this combo with good results. I started with the 17x6 and like it so well I just have not tried the other. Be sure and post some pics as you cover it.
