Collet adapters work because a hole in the adapter shaft (machined to fit your motor or gearbox shaft with precision) is split along it's length several times is forced to contract (usually by the prop drive plate) tightly against the prop shaft. Collet type adapters usually provide a more true center than any other type of adapter meaning less vibration.
Fits 1.5mm(0.06") motor shafts. Presses into 4mm bore props. This is the easy way to adapt the small GWS Hyper Drive props such as the 4-2.5 to 1.5mm shafts found on the ever popular 12mm inrunners and many of the new micro outrunners. Works great with all of then, AON, Fiegao, Medusa, EMP, etc... Each package contains 5 adapters. Laser cut from aircraft grade plywood.
Notes: There are 7 props in the GWS line with a 4mm bore ranging from 4"x2.5" to 5x4.3". Also note the RRC Direct 4x3" prop has a 4mm bore. This adapter will get all these 4mm bore props onto a 1.5mm shaft.
Yes, this internal adapter allows you to run the 5x3 and 5x4.3 GWS HD props on your Sukoi which has 1.5mm gear box shaft.
Fits 2 motor shafts. Each package contains 5 collets. Presses into 4mm bore props. This is the easy way to adapt the small GWS Hyper Drive props such as the 4-2.5 thru 5x4.3" props to 2mm shafts. 20mm inrunners like HiMax 2015 and 2025, Hacker 20mm inrunners, almost all 20mm in runners long or short have 2 mm shafts. Many smaller outrunners also use 2mm shafts. Laser cut from aircraft grade plywood.
Notes: There are 7 props in the GWS line with a 4mm bore ranging from 4"x2.5" to 5x4.3". Also note the RRC Direct 4x3" prop has a 4mm bore. This adapter will get all these 4mm bore props onto a 2mm shaft.
This is an interesting prop driver. Comes with sleeve locker adhesive. It's intended to be "glued" onto your shaft. This gives you the shortest adapter possible. Originally designed for the Gunther props, will work with all the 4mm bore GWS props as well such as the ever popular 4x2.5 prop. Overall Length .474" (12mm). Max prop hub thickness about .350" (8.88mm)
Maxx Products Collet Prop Adaptor 2.0mm(0.08") Motor Shaft to 5mm(0.20"(3/16")) Prop Shaft. Common size for speed 280, 300, 301, 350, 370 and most 20mm OD brushless in-runner motors. Light weight Aluminium, nice nut. Note, this type adaptor is intended for small props and does not have enough motor shaft grip to hold high power 3D applications like 11-4.7 and 12-6 props. However, for props in the 8" and under category it works well and offers a very small shaft diameter so less prop drilling is required.

Prop Adapters and Motor Shaft Collets
A prop adapter bridges the gap between a motor shaft and a propeller, letting a single motor turn props with different bore sizes. This category collects adapters, collets, and drivers for the small electric motors common in park flyers and sport electrics.
Collet Style Adapters
Internal collet adapters step a small motor shaft up to a larger prop shaft, such as a 1.5mm or 2mm shaft driving a 4mm prop. The collet grips the shaft as the nut is tightened, which makes these a clean choice for smaller setups.
Set Screw and Driver Types
For larger motors, Maxx prop adapters use a hex nut and set screw to lock onto the shaft, and options such as a 6mm size or a 1/8 inch motor shaft version cover common combinations. MP Jet prop drivers and a GWS prop hub round out the selection for 2mm shafts.
Match the adapter to your motor shaft and prop bore using the details in each listing.
