Lt,
Smart move!. I know that 100 twin is a real good looking motor but, for the price and what it can actually do I would get rid of it myself. I have all saito 100's in my .60 size warbirds and they fly them great. The G-26 will fly it fine. I even know a guy that put a ZDZ 40 in it. It flew crazy until it tore the wings off it. I use a 18x6 MA classic on the O.S. and it is great. It is a 26cc motor as well. I cant believe how little fuel it drinks. i use the stock tank and fly for about 10 minutes. The thing is still half full when I land. Of course I am not wringing it out by any means. I can if I want but, thats what my ultimate is for. Plus, the 160 runs like a top on 5% nitro. I also put a t-6 TT spinner on. The stock spinner would have to be cut up to much for an 18x6. I know alot of be use them still with this prop but, it didnt do it for me so I got the bigger t-6. I hope you have fun with it.
