fast and good
Awesome No more replacing props Withstands moderate crashes
This was the perfect prop for a 2212 1400 Kv (no brand) motor with a 3s 11.1 battery. It measures 160 watt output with no heating up.
ORDERS TAKE A LITTLE WHILE TO GET TO YOU, BUT GREAT PROPS!
Lots of choices and fast delivery. Better than Amazon.
Great product, Great price, Fast shipping. Told a friend about Master Airscrew, their website. Thanks Tim
great props, great service.
Great prop! Good looking and durable.
A pair of 7x4 props are counter rotating on a vintage Multiplex Twin Star v1 powered by a pair of EMax 2812s. Maybe it's the old style foam plus the metal and plywood motor mounts, or just the props themselves, but the harmonics of this pair are fantastic on a low fly-by. Prop and supplied adapter set fit my prop adapter shaft perfectly and no balancing required.
Great product and just what I needed!
this 7X4 is the prop i use alot of on many of my planes ,although there not indestructible they are a tough prop,
On my modified Albatross plane I am using a regular pitch and reversed pitch props. This twin motor mod really makes this plane fly with plenty of power and can still fly slow for nice gentle landings. These props are durable. This plane is landed in tall grass sometimes and the props do not break easily.
Master Airscrew is simply the best propeller where I couldn't go wrong with any choice.
nice propeller but definitely need balancing
very good prop, a lot less jello in the HD video
Good prop but puts more load on ESC than other 7x4 props. I can use the nitro version on my setup but the 7x4E draws too many amps.
