Just had a thought, even with all the crashing I've done, I haven't bought any replacement props in over a year ~~

Just fixed a busted SMA connector on my TBS unity pigtail, it suffered badly in a recent crash and split in two, nothing a touch of the soldering iron couldn't fix  :D

Carbon fibre reinforced props

new props arrived, they';re CF reinforced, quite a difference in stiffness between these and the DJI props :laugh: but was wondering are full carbon any stiffer and worth the extra cash?

these seem like they';ll do the job nicely.

thx.

bah ma phones knackered the wife';s at work so canny take any just now :( all add some later.

tell ya what though they might be stiffer but balance is way off!

especially the hub, whats the best way to deal with that, i was thinking about a blob of epoxy?

A blob of epoxy should do the job you can always file any access off, I used a blob of hot glue on some  ~~

Pics! :laugh:

IMO i think this is quite a bit of tape to use to get the props to balance right, its insulating tape to which i don';t usually use but i need something quite heavy to even it out.

and the hub well i still need a little bit of weight, that blob ain';t big enough.

the rest look like they';re to be the same.

Hi Nub, I wonder if you had seen a solution I use. You could use clear car spray top coat if you want to keep the black colour. I';ve found that if you spray along the leading edge of one side, and the trailing edge  on the other side of the hub, of the heavy side, your adding weight to the light side of the hub. By careful application you can balance the blades and the hub .

I decided that I should try the tape method, so got some aluminium tape from B&Q builders section. I found that adding the tape to the leading edge and folding it over also adds weight to that side off the hub creating a different imbalance, so rather than adding more to the hub I decided to take the tape off and re apply it to the top centre area of the blade so its either side of the centre line of the hub. The problem was solved and the tape is sticking very well despite my fears that it would be lifted by the air over the prop.

I think I will stick with this method as I don';t have to wait for paint to dry and its a lot less expensive.

My experience of the rctimer plastic props is that they are really weak and poorly balanced. The carbon reinforced props they sell are the same as the plastic ones only a bit stronger and heavier - but just as badly balanced. In fact the carbon reinforced props seemed the worst to me because of the extra weight.

The rctimer fully carbon props seem to work really well but their plastic and ';carbon reinforced'; props don';t.

I think giantshark does good cheap plastic props;

I was having to use stupid amounts of tape to get the carbon reinforced props balanced on my quadcopter before i realised and gave up.
One circlip short of a quadcopter.
 1 lobe short of an antenna.

nub

aye well the plastic props i do have, have taken less to balance right, so it may well have something to do with that telsahed.

i bought some of those el cheapos from QCUK, not sure if i like them suppose they do the job but pretty flexible and they make a weird noise :laugh:

they balanced out quite well though with one of the props not needing anything.

Yeh I';ve got a bunch of carbon props from rctimer and they are all very well balanced.

Hobby king uk warehouse does thin prop tape if u need it.

I use Diamond tape for balancing props. Used it for years and never had  it come unstuck in flight.
