FT P40 - should I expect to break a prop with every landing?

#2
If you have one of the more flexible props they tend to break on harder landings. I have a groupner 8 inch prop dont know the specifications yet though. I've crashed into concrete head on 2-3 times and it still holds up.
I got it at Hobby Town USA

Use APC propellers. Even with hard belly landings and full on nose crashes, not a single one was broken. And this is a full year and a half after I started using them. Also, if your ESC has a brake function then use that to your advantage.

I have also switched to APC props, Broke my first one this week, Took my eyes off the plane while inverted in a low level pass and it went up,, no wait that's down, Broke a lot of the HQ props on the "C" pack motors. I have landing gear on all my stuff, so maybe that helps. Also maybe I just crash less then I did.

I've broken a few APC pusher props on my Versa Wing, but it's been more the tip of the prop striking hard than anything else. HQ props, while cheap, just don't last. I've gone through too many of them with chipping along the edges of the blades, just from regular flying and not crashing. I gave up and went to the APCs, and I notice now that my flights are MUCH smoother, and it doesn't seem to take as much power to take off with them vs the same size/pitch prop in HQ Props.

I used to boil props, wrap in a tea towel and boil in a pan of water for 10 minutes.
Not done it for a long time.

Used to boil all my rc car wishbones and they used to last 10x longer.

It's somthing to do with distressing the mouldings I believe.

I've got some unbreakable multirotors props in the workshop, appatently you can bend them in half and they won't break.

How come you can't use a prop saver?

I found early on that i broke fewer props belly landing than I did with gear on my rough, unprepared runways. As long as you cut power and don't come in too steep it'll be fine...

Here's a whole series of less than graceful landings with my sketchy old FT Cruiser... And no broken props...
