Hello all! would like to get all these different models of 200s, with different engines and props the 470/520/550 , and meet up to have a race together and really have some fun tweaking these lil ferraris of the sky. Check out the sport air racing league and sign up, John and I have had a few runs, at race settings 259M will turn 2750rpm at about 27in 2K to 3K altitude will usually indicate about 216-218 mph with a TAS of about 220- 222mph (193Knts) burning 23-24GPH at 75 deg ROP EGT 1425 with CHT around 360 depending on ambient, the real trick to going fast is getting the planes clean and tight with no extra antennas and lights, + good flap and gear door seals, An good trim job by setting the flaps and Horiz stab for a straight and flat running plane ( ball centered and elevator in line at full speed without any excessive trim 🙂 Now at travel setting I cruise = 7K 10K will turn 2350 at 21 inch burning around 16gph and TAS of 200-204mph 177kntas
