Prop Savers for FT motors??

I'd love to see prop savers for the FT "A", "F", and maybe "B" Power packs. There don't seem to be any of these for the larger shaft motors. The "A" and "F" motors use 5mm shaft with a 5mm x .80 threaded portion. The "B" is 6mm with a 6mm x 1.0 threaded portion. I may just try to make prop savers for these.

I hope this is the correct place for this post. If not, please relocate it somewhere more appropriate.

Hope everyone has a great time flying this weekend!

They probably dont make them because the power these motors put out. I would Imagine at some point they would just pull off the fitting on a prop saver I would think the best thing would be like a one way bearing from a helicopter rotor but a free wheeling prop is not always the best thing either.

Prop saver on a pusher, maybe. If you are using props at a huge rate, try glow fuel props. The thrust loss makes up for the fragility

Just keep a strip of newspaper paper between the prop and the motor rod and keep the spinner on slightly loose. I discovered this by accident. When the prop is forced to stop, the prop will stop but the motor is on. Then the motor spins off the prop and the spinner in under 2 seconds. If you're not careful you can lose the prop though.

We are having the same issue. We have an "F" power pack on a mini corsair. Since it is a belly lander I'm not clear on how to avoid breaking a prop. I'll look into the APC props but I worry that in indestructible prop will bend the motor shaft. The only other option I se is to 3d Print a prop but I doubt it would hold up to the RPMs

I haven’t broken any props on my mini Corsair except in one crash. Are you landing on concrete?

Set the brake on your ESC so when your landing your plane it’s not spinning when you touch down
that will help

I found an older motor with a thinner shaft that can accept a 3mm prop saver. I mounted this on my Eagle, but I really messed up the CG.

Is the esc that comes with the flite test power pack programable?
I can’t honestly say as I’ve not bought one, most ESC are however after looking at ft store and ESC‘s they sell it looks like there is no information leaflet in the packaging so I would say no they are not

Shadey; I'm not saying they are, but they are likely to be. Most ESCs are programmable, in this case Youtube is your friend. Connect the ESC thru the throttle connector and an interface. REMOVE PROP!! Found this doc on the net; cumbersome, but can be done just with the transmitter. https://www.tme.eu/Document/959503479e9fa7b0e61049c62875b2e2/BLHeli Instruction.pdf

When I try to use the description in the link I definitely get an assortment of music however it does not seem to correspond to the description. I am assuming that this means it is programable but not an Emax BLHeli. I have done a number of searches on programming Flite test and who make the the flite test esc but so far nothing
