FastEddieB Posted November 27, 2014 Report Share Posted November 27, 2014 Isn't there a difference between an adjustable (in air) and a constant speed prop? Yes, though the terminology can be confusing. In-flight adjustable would typically give you a control that directly changes the pitch angle of the prop. Constant-speed props use a governor to maintain a given rpm (to the extent possible). Think of the former as a manual transmission and the latter as an infinitely variable automatic. BTW, either would be a blessing in our planes - I'd get one in a heartbeat for my Sky Arrow were it legal. Even Experimental, I must still not make mods taking the plane out of Light Sport limitations. Link to comment Share on other sites More sharing options...
Doug G. Posted November 27, 2014 Report Share Posted November 27, 2014 That's what I thought. CTLS only comes (non US) as an adjustable prop, right? Not constant speed? Link to comment Share on other sites More sharing options...
Anticept Posted November 27, 2014 Report Share Posted November 27, 2014 Ground adjustable. The four prop classes are fixed pitch, ground adjustable, variable pitch, and constant speed. Link to comment Share on other sites More sharing options...
Doug G. Posted November 27, 2014 Report Share Posted November 27, 2014 I believe that there are variable pitch props on some European (and Australian?) CTs. They are not limited by the same light sport rules. Link to comment Share on other sites More sharing options...
samifer Posted November 27, 2014 Report Share Posted November 27, 2014 Mine (canadian) has a constant speed ..... but i cant do 135 kn:( Link to comment Share on other sites More sharing options...
Jim Meade Posted November 27, 2014 Report Share Posted November 27, 2014 Mine (canadian) has a constant speed ..... but i cant do 135 kn:( What prop and governor do you have? What is your reflex flap setting? What is your RPM and prop pitch for WOT at your cruising altitude? Link to comment Share on other sites More sharing options...
sandpiper Posted November 28, 2014 Report Share Posted November 28, 2014 Flatten your prop pitch by 1.25 degrees and go fly. You'll be happily surprised. The prop adjustment should only take 45 minutes. Roger - what happened to the 30 minutes I lost a bet over?? Link to comment Share on other sites More sharing options...
Anticept Posted November 29, 2014 Report Share Posted November 29, 2014 So I just installed a sensenich prop on my CTLS. Getting 126 knots indicated (up from 119)... Granted its cold and the density altitude is negative so I am generating a little extra HP, but it was a nice surprise! Link to comment Share on other sites More sharing options...
Anticept Posted November 29, 2014 Report Share Posted November 29, 2014 126 KIAS? What's your KTAS? Don't know. Didn't really worry about it, we use my CT for flight training. I do know I saw quite an increase in indicated airspeed, but the 119 was when it was warmer, so take the exact increase with a grain of salt.
