How to make the new APC Electric props fit your adapter

HI I have found that all my E prop APC's are much too thin for my prop adapters and I cant tighten down the prop screw on the adapter.Has anyone else had this problem? IF so can you let me know what the fix is.
Thanks Joe

Joe,
I had the same problem, my solution was just to scrounge up enough of the appropriate size washers to make up the thickness difference.

Had exactly the same problem.. finally scrounged up a few aluminum washers to fill the gap.
Frustratingly though I've found these props to be less than expected performance/price wise.. I won't be buying more.

Yeah, I think I'll stick with the MAS/Grish props myself.

I used the outer plastic stopper, about the diameter of a quarter, from one of my glow fuel tanks and it works great. Made from plastic and adds no weight and is about 1/8" thick. Tom

Thanks Guys, I think I will use the Gruapner cam props and maybe some MAS wood props. If the performance is not what is expected.

The early batches of the APC thin-E props had a very thin hub (and the TE of the blades going well aft of the hub face). Current production all have a thicker hub and the blades project back little or not at all, so a spinner can be fitted.

Bare, what was you application? The MA-E props may work better than the APCs at really low RPMS (say 4000), but beyond that the APCs I find much more efficient. You may need to go up a bit in size, though. I was running a 12X8 MA on the LT-25 and now use an APC-E 14X7 at just slightly higher current draw. MUCH better climb and overall performance is similar. I need to try a 13X10 on that power system.

Just a happy customer - I've gone completely over to APC-Es on my current fleet.
