RE: Slowing pattern plane
Oh, one more thing. I do not recommend spoilers because I got lucky guessing that they would work... my plane had the same characteristics he was describing and I was trying to use flaps to cure it. Then a guy I used to fly with, Bryan Hebert (yes, designer of the Storm and Patriot), recommended reversing them to spoilers. Well, Bryan being who he was, and with all the area knowledge that has been derived from Nat Penton (Voodoo man himself whom I consulted yesterday on prop selection for my plane), I tried it... it worked wonders and I haven't looked back since. Oh, and by the way, spoilers will not increase your rate of decent provided you manage the throttle and elevator correctly. However, by definition the purpose of flaps is to provide a steeper decent without an increase in airspeed, they give you a higher angle of attack without the larger amount of the airframe exposed to the airstream, and they increase lift in an airplane that already has too much (if your plane is already flying too fast, adding flaps will only make it float even more). Unlike the previous posts, these are not humble opinions, they are based on facts taken straight from full-scale aviation and testing both ways on my airplanes that have experience similar problems. I have never tried the propeller change since I do not want to reduce the pitch of the prop that I use. My recommendation would be if you are pleased with the performance you're getting in all other stages of flight, why change to a lower pitch propeller and reduce it's pulling power for vertical maneuvers? OK, that last bit was IMHO...
