Hello Bjorn,

 

1) 880Kv with the 10" props allows you a better flight, plus you can add the extra inch or two props later on should the need come about to lift more weight.

2) Optical flow sensor is on for the APM 1 & 2, in the Wiki "software support for the APM2 will be available in ACM code 2.6 (and above)"

3) Yes, I have both sitting on my desk..... (not CF)

4) Are we talking light tree contact.... ;) I have not yet seen a prop that will put up with being stopped by an object, there are stronger props (stiffer) and these have a little more resistance to being "hit", the "grey" ones I have in stock seem to put up with a good amount of abuse....

5) Not sure on this one, you will have to ask the guys at 3DR however I see there is a full 3DR hexa kit in stock at a UK dealer..... now, who could that be :)

 

Regards

 

Martin.

Thanks Martin  

1) I also suspect the 880 - 10" might come out nice since shorter props allow for faster transitions and smaller ambient wind resistance. Maybe the difference is minimal but... I'll try that first. 880 can carry larger props and should give a bit more rapid rpm response with the shorter props if I am not mistaken?

2) I guess the geek inside me is moaning after an optical flow sensor so I'll have to order one sooner or later.

4)The black props I got originally from Jdrones fell apart from just looking hard at them but the grey ones a certain UK dealer was peddling last year have stood up to incessant beating. The brushes In my backyard are no match to them. 

If that dealer has similar stuff lying around I may consider ordering a handful. Do the ones that come with the 3DR frame+motors kit meet the same standards?

Anyone have further comments on "best props"?

1) Yes and no, there will be less resistance to turning the blade, so yes there will be a better spin up spin down as the energy in the blades is not so high, I have a number of customers running on the 880 and 10" props, so far they are going well!

2) These things are not want's for long; they become "needs"

4) I'm sure I don't need to remind you they are not for trimming the bushes..... There is other equipment to carry out bush control! ;) I still stock the same props as last year so look at them and fall apart, or grey one which will look back :) The kit's come with APC props which are grey and look to be about the same as the ones I have in a matching colour.

Hi Bjorn.

I have a jDrones kit and I have had a couple of crashes with these props and they have held up quite well

At least they seem to be much stronger than the first set - which lasted 1 crash. In fact, the motor mount broke in the last crash and the props are still in one piece.
