Paraphrasing, it takes off shorter than most and I won’t be limited by its STOL capability. But will always want to go faster. Which is true.

Finally a photo of @LeeGriffing’s airplane on here… bout time!
Thats a J3 - for peasants!
The pitch of my model of borer, the 82/41, is more shallow (i.e. climb oriented) than I like. I have the opposite problem and need to watch RPMs. Your static does seem low so I think you can benefit from a climb prop, just be careful not to go too far. Definitely helps with the airbrake but without flaps, cubs are pretty slippery. Can add some big tires and uncover the landing gear. That’ll create some drag.
What are you getting static? I’ve kinda calculated it out where I should get max continuous RPM in a Vy climb. I’m going to be doing 850s for sure but going to keep the gear covered. I can manage, but just want a little help slowing down.
I’m actually impressed it got that far along with accuracy with a super brief prompt. Even a few months ago it’d generate some abomination like the original pilot ground logo.
Better than the airbus sidestick that totally didn’t look like a glossy d*ldo.

So my brother installed a 71 inch diameter 48 pitch metal propeller on the Super Cub. Coming from a 72 diameter, 50 pitch wood propeller. I only flew it once with the new metal one and it was windy so hard to tell takeoff and climb performance. I THINK it’s better. We did gain 3mph in cruise, which was not the goal but it’s kinda cool on the fixed pitch side to improve both sides of the equation when it’s usually a trade off ie: climb or cruise, not both. I don’t want maybe better, I want definitely better climb performance and airbraking on landing, so planning to pitch it down to 44.

Damn,
I didn’t realize that he got his A&P in April…
Tell him I said congratulations!
I’ve always been tempted to get it.
I always thought @Dr.Badass and you should get it as well sometime!
@BOB I tend to agree with wanting more climb but don’t want to cash in all the cruise I have. With only 18 gal of fuel, every mph is coveted. So finding that balance is the mission.
I have access to a metal Sensenich 72 diameter 44 pitch to try. Hopefully doing that next week. I’ll have testing data to supply @IanArendt

Nice! Should be a big difference from what you had. How’d the 72/48 work?

@IanArendt the Metal McCauley 71/48 was BETTER all around than the Wood Sensenich 72/50. Gained 3mph in cruise and maybe 10% better takeoff and speed brake effect. Like adding a cold air intake to your car. Your car is faster only because you know you put it on.

Sounds like you found the unicorn. Maybe the added weight changed your angle of attack and gave you a few mph?
@IanArendt I think its the fact our prop slip went from about 6% to almost 0. Those wood props are just not efficient at all!
It would have to be an aft CG move to improve performance and I gained 21lbs right on the nose
