I have owned and flown an M10 for several years now. They are two place with a Continental C90-16F at 90 hp. Gross is 1450 pounds with an empty weight of ~1000 lbs. Mine, in summer in Florida with me (215lbs) and full fuel (24 gallons), will climb at 500-650 fpm. In the winter it's 850-900 fpm. At full gross, I can get 450 fpm even in the summer. I cruise at 2300 rpm, ~100 mph, at 6.1 gph. I have no issues whatsoever with the seats being uncomfortable and the seats go back far enough for pretty much even the tallest pilots legs but there is not much canopy clearance over my head. I have climbed to 12000ft and the logs show a climb to 15000. At 10000, at 2300, I am burning 4.1gph with a 71/53 cruise prop. Best climb vx is 73mph with max vertical vy at 64 mph. Stall is around 50, I say around because the high angles of attack required to stall makes the ASI goofy. Approach speeds are 75mph with speed bleeding off pretty quickly in flare. Engine off glide ratio is 6:1. If the motor quits, look down as that's where you are going to land. You can fly with the canopy open but cruise speed drops 5-7 mph.
I have updated mine. I have a lightweight Skytech starter, a 40 amp alternator, removed the vacuum pump and installed two Garmin G5s, EI engine analyzer, EI fuel flow meter, Garmin 796, Appareo Stratus EG ADS-B out, King kx-125 nav/com with Ki 214 VOR loc/gs., Stratus 2 ADS-B in with ipad Pro running Foreflight, Whelen nav/strobes on wings and rudder, new Millenium cylinders, spin on oil filter, and . It is a good instrument trainer but I would really not be interested in flying in any serious IMC conditions. I have taken 500-600 mile trips in it and it works perfectly unless you are in a real hurry.
Mine is serial # 690001, the very first M10.
