The GForce 2206 motor at $21.99 suits indoor and parkfly 3D planes, and the shaft type decides how the prop mounts. The threaded shaft version holds the prop with a nut on a 5 mm shaft. The O-ring version holds it with a rubber ring and lists 400 g of thrust. The 2008 version at $15.99 suits park flyers.
Threaded shaft or O-ring?
The threaded shaft version holds the prop with a nut on a 5 mm threaded shaft.
The O-ring version holds the prop with a rubber ring, so no nut is needed.
Pick threaded when you want a nut-held prop, and O-ring when you want a quick prop change.
What does 1500KV mean here?
KV states how fast the motor spins per volt with no load.
A 1500KV motor on 3S spins faster than a 1250KV motor on the same battery.
Both 2206 versions list 1500KV and a 3S battery, and both weigh 29 g.
Where does the 2008 version fit?
The 2008 version spins at 1250KV and suits smaller park flyers.
It fits a 2 mm bore on a 5.5 x 3.3 folding prop, per its listing.
It runs on 2S or 3S, and it fits a 40-inch Lollipop ARF.
How much thrust does the O-ring version make?
The O-ring version lists 400 g of max thrust.
That thrust suits a light indoor or parkfly 3D plane at 29 g of motor weight.
Match the prop to the motor KV and the plane weight before you fly.
What did we check on the bench?
We matched the 5 mm threaded shaft and the 29 g weight to the threaded shaft listing.
We matched the 400 g thrust and the 29 g weight to the O-ring listing.
We matched the 2 mm bore and the 5.5 x 3.3 folding prop to the 2008 listing.
