I got my MR Aerodesigns Porter last year and started on it in May, made pretty good progress on it so far just in the final stages of closing up the wings, had to install hard points for the extended range fuel tanks (dumby) or the skydiver drop unit. Anyway, going to power it with the Revolution 52 because of the long snout the motor has, will fit nicely into the cowl, also using a KS canister muffler in side the fuse to keep it quite, but haven't gotten to that stage yet. Also planing on using it for Aerotowing, won't be a rocketship but it should look good going up at scale speeds (50 mph is about the right speed anyway). Also going to use an Eagletree flight telemery system to monitor airspeed and altitude ( they're working on voice anucianation feature now).
