TBM's 23x8 Prop
Recently I tested one of TBM’s 23x8 props, and was impressed by the looks. I tested it on a Desert Aircraft 50cc engine, replacing a Menz 22x8 as a break-in prop. The Menz made an Extreme Flight 88’’ Yak - 54 fly great. The TBM 23 x 8 produced a reduced amount of RPM. Also, during the flight, the airplane flew with a lot less power. For example, after a hover the plane had a harder time pulling out. After a few flights I switched back to the Menz propeller and let another flyer try the TBM prop on his Chinese made engine. He had the exact same results as I and wasn’t impressed either.

Well we have run the 22x8 as a break-in prop on the DA50 with about 6-8 gallons through it. We thought that may have been enough, but possibly not. With the 23x8 we were hoping to get a better pull-out from a hover and through some various other maneuvers. Another reason we went with a 23x8 is that DA recommends it after break-in. This may not of been the right thought process but it is what we felt was the right direction to go.

RE: TBM's 23x8 Prop
is the set up on regular mufflers? The menz is actual a 21.xx prop anyway. I do love Menz prop and think that they do 3d very well. Most 23" props seem best on a pipe or can to me.
