What is the size of the prop adapter?

is there any alternative to these motor?1806 2900KV micro motors can be used?
 BrianB192 1758 points
if your using a small 200-250 frame you have many options, If you want 5 amp . or 10 this size quad. so be aware of your frame size limits. Frame size will limit your Motor choice. What have you go as frame. we can get you Many cheap alternatives with 2mm shaft. such as this has. , I ordered the new folding props 5030 with 2mm size fitting for prop adapter for them. the Motors I say are Very week. and seam to never last Long,after a few crashes . Ive had 3 defective ,or seam to start playing up shortly after a cash. So what fame and board are you using. Go and Look under motors for multi rotors and Aslo look in brush less motors hear As I will now and see what we can find,..

Maybe you search for inch-Allen-keys. 0.05er fits for the bigger one
Paul  6 points - 6/6/2015
Hello, i hope someone could help me out, the issue is the shaft is loose, but i can't find the right allen key that will fit, to tighten the set screw on the shaft. So i bought on ebay a micro allen key set but the 0.9mm is too big and the 0.7 is too small. So i think 0.8mm is the right one, but it seems like it will not exist, i've searched everywhere for it, but i can't find it. I need help, how can i fix this? Or is it possible that it is in inch instead of mm?

Same as me, very hard to find. I use a micro Torx bit that came in a cell phone repaire tool kit.
 Paul 6 points
Thanks, i shall try that!
 BrianB192 1758 points
Yes Quite , to Verify that, Ebay cell phone repair kits have the small Keys / Micro Hex key. that I used to pull it apart/tighten, . It has 3 type Size keys on the motor. the kits Have them covered. its very supprizing they are so small. ,watch out for defective Motors ,Loose, Shafts, all screws Are Often loose. Its A Very good Little Power house motor. on Quads otherwise.

This brushless motor works really for for a twin brushless system for the E-Sky Lama 4. Excellent motor that stays cool to the touch after flying. Highly recommended -

Klasse Motor.
Die Wicklung sieht zwar aus wie Sau, aber geht auch wie Sau.
Luft super rund, und zieht an einer GWS 4x4 bei 2s knapp 6A bei vollem Akku. Sind ein paar mAh raus geht der Strom im Flug deutlich zurck.

Verbaut ist der Motor in dem Arrow von Jomari. Das Modell ist ein richtige Rakete. Klasse!

Motor is on the foam Mustang span 51 cm, weight 120 gr. Prop GWS 4,5 * 4, Battery 2s 350 mAh. The thrust of about 135 gr. The plane goes straight up. Features of the engine exceeded my expectations.

This has amazing torque for the size of the engine. I was expecting to have a not very powerful motor since I went for light weight but HK proved me wrong!
