Description

A pair of very high quality VM 11 x 7 folding prop blades, suitable for Vladimir's Models new Pro Spinners and other folding prop yokes and spinners.

These blades are extremely thin (they have a higher aspect ratio), thinner even than GM blades. This allows larger diameter blades to be fitted without pulling too much current. This increases the propulsive efficiency of the powertrain. When used with VM Pro Spinners they will fold closer to the fuselage, and cause less drag than other props.

Note this product consists of two carbon propeller blades only. The central spinner/yoke assembly is not included. Also it is common for prop blades to not fit all spinner/yokes perfectly as supplied. It is often necessary to reduce the width the blade root slightly to ensure free folding movement. Also the cut out in the spinner cone often needs to be increased to allow the blades to fully extend. The root of the blade should not touch the spinner cone when the prop is fully opened.

The VM folding prop blades go very well with the VM pro spinner.

VM 11x7 BLADES

My "old" Eroplan Kappa 35, motor Mega 16/25/4 CE F5J, ESC YGE65 LVT on a 3S 95c LiPo pack got almost twice the thrust compared to the old VitaProp 10x6. Current consumption went from 28A to 39,8A which is perfect for that motor in a F5J model(maks 30s runs). The plane now shoots like a bullet when searching for thermals and climbs vertically if I want to. I am very happy that I found a much better match for my model and the prop looks soooo clean and it folds really close to the fuselage (Hyperspinner Power 38mm) Very good product and as always quick delivery. Thanks Hyperflight.

VM 11x7 BLADES

took two weeks to get from england to New zealand ...........not bad in the current environment .royal Mail Untracked.
Tried them this morning on my newish eflite Radian.
Half throttle 10 second climb was sufficien t for thermalling,much better than the stock prop.

I have seen too many internet photos of the smashed front ends of Radians after the stock prop exploded and took the front off the model.

I used a no name alloy 50mm spinner ,the blades being a perfect match,and fold tightly to the fuselage sides ..money well spent.........

Blade size

Unused as yet, hence the rating.
Very neat fit in a vladimir 32mm spinner.
Worth noting that the diameter on this centre piece matches the specified size. Other props Aeronaut/Graupner are usually sized based on a bigger middle piece.
Very light,slim and neat fitting blades.
