    42mm 1.6 pitch seems to be popular. so much so that literally no one has one from any brand in stock.

    OSE 4214250 $20 is good for 6s or a custom one from Dashbota.com I have both.

    Yes I have that same OSE prop. It is a 1.65 (42mm) diameter with a 1.4 pitch. Same total pitch as an Octura X442 if you can find one of those as well. Its a very commonly suggested prop for the UL-19 to keep the current draw and temps down, although I dont have that specific model myself.

    I run mine in my 36" mono on 6S if I want to run continuous heat racing laps. I use a 1716 which is the standard prop setup on the Pro Boat Miss Geico twin for SAW like fast laps on the same 36" mono. It will run 80mph on the 1716 prop, but you have to be careful with the temps on 6S and let it rest between runs a bit
