Cheap but low performance and heavy

May 16, 2018

I did static thrust tests comparing these against:
GF 6030
DIATONE BULL NOSE POLYCARBONATE 6040
HOBBYKING 6050 BULLNOSE PC
In theory they should be somewhat middle of the pack in terms of g/W but they were the bad outlier, 46% worse than the 6030, 24% worse than the 6040 and 27% worse than the 6050 at pulling just 200g (close to mid throttle).
Not only that but they're the heaviest at 5.5g compared to 3.5g to 4.5g for the others.

Hub is a bit too fat, my lock nuts have very little threads left for the nylon part to lock.
Besides that, the hole for the shaft is slightly too big, there is a little bit of play between the shaft and the prop.

Another pleasant surprise!
I bought these alongside Gemfans partly out of curiosity, partly as a set of expendable practise props for bashing around in the bushes with my baby beast 250. Now i prefer these!

Less efficient than the glass fiber reinforced ones, but quieter and tougher. They dont break, only bend: A great plus for safety.
