Cessna 170B Sportsman STOL: PIREP

[amacbean]

That's what I was looking for! Thanks for the information guys. I knew the Horton kit was close to the later wing cuff/roberston wing, but I didn't realize how much the Sportsman added beyond that. I'll go out and do some tests like Rob did and see what the difference is. Maybe this is in my future, along with bushwheels, MT prop, new paint, new interior...

I did kept my Horton wingtips they have bigger area than the ones Stene offered at the time , and they recommended me to do that.

Have not seen the new tips in their website.

Has anyone noticed a decrease in performance on climb to cruse performance with the Sportsman STOL? My cruse performance is the same, my VX is horrifically better, low speed handling is dramatically better, but the one thing that seems to suffer a bit was my climb to cruse performance. My norm was 100mph and 950-1000 ftpm now after the Sportsman its closer to 850-950, am I the only one?

I just put a kit on my plane.
This link has pictures of the work along with pics of the wingtips.
Hasn't been painted yet.

If Vx is drastically changes, maybe Vy is also. I'd check climb rates at different airspeeds until I found the sweet spot.

I noticed my plane wanted to climb a lot more FPM at 65mph then at the old VY. I'd try different airspeeds as hotrod150 suggested.

Flap gap seals - off. Improved performance - yes. Thanks for the input.

Pretty cool to get a free performance boost huh? That doesn't happen very often.
