mikeh Posted June 14, 2012 Report Share Posted June 14, 2012 Hi I am new to Ryan flying. Does anyone have some handling notes / pilots notes / instructor guides to share? Thanks Mike Link to comment Share on other sites More sharing options...
ozryan Posted June 16, 2012 Report Share Posted June 16, 2012 Hi Mike, I have some info at home, but am on the road for a couple of weeks at the moment. I'll try and get something to you soon. What c/n is your STM? Link to comment Share on other sites More sharing options...

The tail comes up pretty quickly, and I let the airplane fly itself off about 45-50 knots (don’t try to haul it off). Accelerate in ground effect to about 70 knots and climb away. Select fuel to main above 1500 feet. Cruise about 1900 RPM, an (depending on your prop) that gives about 90 knots. Endurance is about 2 hours plus a reserve of 45 minutes (don’t try to stretch this). Approach about 60 knots on final, and touch down at 50. I usually don’t use flaps (for takeoff or landing) as they seem to blank airflow over the elevator. Limit crosswind to maximum 10 knots, as it will easily swing with the narrow gear track. Flaps and crosswind is a bad combination. Rudder is very effective from about 10 knots. Weaknesses of the airplane are the brakes (absolutely for taxying only), and the narrow gear track. Make sure your mechanic checks the oleos and gear legs regularly. Tires are hard to find (3 inch Goodyear airwheels) but I got adaptor plates made to take 4 inch Cub tires, available from Desser. Supercharger seals (leather) tend to leak after a while, and are hard to obtain. Many Menasco’s have a mod done to install an oil shutoff valve, to prevent oil draining down into cylinders. Ensure this is installed in such a way that you cannot close the cowl access door unless the shutoff is turned on. Grease the rockers every 10-15 hours, as they throw a fair bit of grease. You won’t find a sweeter machine! Link to comment Share on other sites More sharing options...
efremcockett Posted September 26, 2014 Report Share Posted September 26, 2014 Hello Guy, I have just started flying my newly restored STM-S2, s/n 458. I have read your comments on the prop giving an airspeed of 90 knots. At the moment I'm running a Sensenich W80R-70, which I gather should be an R-72 for this version. I'm only getting 100mph (87 knots), whereas everything I've read from the original books says I should be getting 138mph (120 knots) in the cruise at sea level. Any ideas? Sensenich say the R-72 prop will only make a cruise difference of 3-6 mph. Efrem Link to comment Share on other sites More sharing options...
