Unit Weight (g):
These are great quality spinners at a reasonable value. Some slack in bolts and you might need washers inside the propellerblade space to get it to not wobble. But really universal. Have not yet met a blade I couldn't fit on these. Multi adapters make it fit most motors. This is the smallest one I bougt, mostly because of the blades.HEADS UP!! This propeller is a true danger to anyone that try to use it with any motor that have a shaft that is not the diameter of what it have out of the bag!
I put it on a slight larger motor and almost eviscerated me !I was trying to balance mine and one of the blades was defective, It literally blew up half of my plane! rip off my computer speaker in half and also destroy totally the motor mount of my hawk skywalker!
I find myself very sad that this happen! I lost tons of equipment and get nothing in return! I also have to wait for over 6 months to find this propeller in stock! """":-(The efficiency of the propeller is very poor.
The trust produced with this propeller was 450 gr and almost 15A(on 3s) but with the same setup and a normal 8x6 propeller the trust went up to 710 gr and only 13.5A(3s again).
And besides these parameters in just second flying during the landing and with no throttle one blade was broken without obvious reason maybe some hard in the field but it was my first broken folding propeller ever.Fragile at the holes and very poor thrust to Amps efficiency. With normal prop at the same dimention and the same Amps you have at least twice the trust.Trs mauvaise hlice, rendement trs infrieur une graupner 8x6, le modle se maintient peine en l'air alors qu'il montait quasiment la verticale avant...
Very bad prop, less efficiency than a 8x6 graupner, the model flights hardly when it was barely climbing vertically before...cone et helice en plastique trs rigide et de bonne facture
Le cone fait 32 mm de diametre et le pied de l'helice fait 5,5mm d'epaisseursjkadfhouishf sdjklf hkjlsdh afkjsdfExcellent quality for powered glider..nice and cheap propeller. heavy duty prop
