Dave,

The 18 X 10 should work better for you. If not you can try an 18 X 8 three blade. It might load you engine enough to get the job done. I'm running a 20 X 18 three blade. It sounded like it was loading the engine correctly with the plane on the test stand. Not sure though as I have not flown the Decath yet. I'm running a ZDZ 40 which may have a little more power than a G38. I have never had a G38 so I'm unsure of the power it produces. I've talked to a couple guys at the club that have flown them and they seem very happy with them so it must be a pretty good engine.

nh4cio4,

Was not ignoring your post on the Seagull pants. I'm not familiar with them and was hoping someone else would address your question, so I would learn something also. Evidently others are not sure either from the lack of response.
