Pietenpol-List: Center section cut-out

Original Posted By: "Hubbard, Eugene"
Just a quick post to pass along some actual info from carefully researched flightdata. Mr. Pietenpol said that center-section cut-outs would affect climb performance.In my Piet I have a "flop" from F&G and up until yesterday it had been unsecuredie. free to "float" while in flight. I noticed that, while flying, I couldreach up and pull it down with one finger and that would result in a noticeablenose-up tendency. Yesterday I put a catch on it so it would stay down (alignedwith the rest of the wing T.E.) and it occurred to me that not only did thePiet climb better, but I didn't have to use nearly as much aft stick in straightand level flight.Based on that highly controlled and carefully conducted experiment, my conclusionis that Bernie was right AGAIN!! If you have a center-section cut-out or anunsecured flop, you are sacrificing lift/climb performance. All this might not be such a big deal to you who are using the "big iron" but forus in the model "A" brotherhood, every little bit helps. Larryps. the flop only trailed up about 1/2" prior to installing the latch on it.pps. I just got my wheels back from Buchanan's. I might have to re-do my W&B!!!!!!________________________________________________________________________________
