Well, after about 30 flights on my 4 * 40, it augered in through the trees yesterday. Don't know what happened for sure, but as it headed down a full throttle I had no control. Oh well, time to build something new. I'm considering the Sig SE for my next build and was wondering if there are any recommend mods to it like with the 4* (sheeted turtle deck, enclosed cowl, clipped wings, enlarged rudder, etc.)
