Скачать или смотреть KING KONG 6045 BN prop test - cheapest, most durable prop?

After being extremely happy with the durability and punch of the DAL 6045BN props I was just about to buy a stash of them and came across these. Apparently they are even tougher still and quite a bit cheaper too at under £4 for 10 pairs.
They are not going to be the most efficient or fly as well as some stiffer props could but I want absolute power and durability before efficiency for this beater and they certainly seem to fly very similar to the DAL.
The kicker was they came really close to perfect balance and only half a dozen out 80 props needed more than a few passes with sand paper to balance the blades or hub material removing rather than a massive dab of hotglue.

I got these from Banggood, they also have non bull nose and 6030, 5045 and 5030 at same prices and even some choice of colour.
