Product Description

These high RPM 8 x 4.0" props are a matching set of 2 x CW(R) and 2 x CCW(standard) low pitched multicopter props.  These GWS 8040 and 8040R are the bomb on 4S 750-800kva motors for Multicopters at low total airframe take-off weight of .  They are very easy to balance with tape on a magnetic balancer and run extremely smoothly. Once you have worked out the balance for one - they are all the same.  The real bonus of these props over the 2 bladed slow flyers is they hold their tip tracking at much higher RPM, yet they are so light they chage RPM very rapidly and have NO gyroscopic-precession feedback when twisted rapidy - as you would when doing hard manoeuvres in a Multicopter- no gello when balanced - Sure we all know they wives tales about triples being hard to balance - and we are aware theat two bladers are more efficient - but after doing a lot of real world perfrmance and balancing tests - HD Video Ops - we HIGHLY recommend these for 4S 750kv CarbonBird motors - on lighter quads like Armour
