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.

Dynamic test results,good stuff keep it coming! got any xoars to try would be great,thanks!

22X8 vs 23X8 ??? Apples to oranges??

Good point.

Taildragger,
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.

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.

A friend of mine said he is getting 35lbs of thrust with a Vess 23A on a DL50...

kewl

Yes, we did have it set up on a standard muffler.
