1980 Turbo-RG Skylane with 3-blade MTV-9
the MTV-9-B was consistently 3 to 5 knots FASTER than my old propeller

Martin,
I want to thank you and the team at MT Propeller and Warner Propeller Service for the quick resolution to the fit problem of the MTV-9 propeller onto my 1980 Turbo-RG Skylane. I am very pleased with the final spinner to cowling fit, which now ranges from 12mm to 15mm.
I test flew the plane yesterday at 8,000 and 12,000 feet MSL. Climb to altitude seemed similar to the 2-blade McCauley propeller but it is very hard to duplicate conditions. What surprised me was the true airspeed at cruise. Most everyone told me to expect to lose as much as 10kts at cruise. That was not the case. At power settings from 40% to 75% the MTV-9-B was consistently 3 to 5 knots FASTER than my old propeller. The 2-blade McCauley had 2200 hours total time and 400 since overhaul so I expect it would also be better when new, I am still impressed with the performance of this MT propeller. The MT is indeed very smooth at all speed and power settings.
I am looking forward to taking it on several long trips in the near future up higher (17,000). The higher I went the better it seem to be over the 2-blade metal propeller.
Thanks,
