3 blade props

[powerlord]

I';ve been running 11x5 graupners on my DJI F450 NAZA (4s).

And it runs nice enough - smooth - no jello, etc.

I broke one last week, had no spares, so stuck on a set of 9x5 carbon props from rctimer.

These too were fine - less lift that the graupners (obviously) but they got it off the ground and were nice and stable.

Last weekend though a friend recommended giving some cheap 3 bladers a try.

I got some off ebay : cheap plastic 8x4.5 3 blades... I got them in blue to be less visible when the gimbal brought them into view too.

And blow me - if they are not very very good... (and I';ve not bothered balancing them or anything yet)

Almost silent compared to the graupners - and still much much quieter than the 9x5s. Seem to be as smooth, and giving more lift than the 9x5s (though maybe not as much as the 11x5s).

The other benefit, is that they are smaller and therefore less prop shows in the video when I';m going full speed forward.

If you';ve not tried a set of 3 bladders it might be worth a go for a couple of quid ?

I';m gonna order a set of 9x4.5s now - I think they might be the best size for my setup.

You might find they pull more amps though.

sure - especially the 8s : Im only getting 5 vs 7 mins now. I';d imagine the 9s will be back to around 7.

However I';ve went back to the 9x5 carbons for now.

It seems to me that the light little 8x4.5s though smooth don';t have the circular momentum of the larger props - making the quad a lot more twitchy in the sky - even with the brushless gimbal it';s actually worse than the 9x5.

So so much for progress. I think that';s why the 11x5s were so good - over propped maybe - but for camera work it just help keep it from any sudden movements.

I';ll probably try to get some new graupners when ever they start to be in stock again.
