Thought I'd got the right motor.

I'm just starting to put my Pheonix 2000 together but found my choice of motor has a 3mm shaft and the folding prop has a 4mm collet. Looking at the spare adaptors in the box there is a 3mm adaptor but the shape of the collet will not fit the nut shaped collet half in the prop. What can I do, replace the motor or the folding prop ?

This is the motor I got **LINK**

I started thinking maybe the motor is a bit small if the glider prop needs a 4mm shaft ? I'll ask a question in the glider section idea

Obviously changing the prop is the obvious thing to do.

However, I fitted a Gliderdrive motor to my Phoenix. They're more expensive and more powerful than actually needed but you can always prop appropriately to get the power you want and the motor will be working well within its limits. They also fit very neatly in the restricted nose with easily accessible rear connections.

So if you can find a use for the motor you already have in another model it's worth thinking about a different one.

Just had a look, that motor has a 5mm shaft which would put me in the same position unless it has an adaptor to fit the prop at 4mm.

I've deleted the other thread you've started on this subject, trebor - otherwise things might get complicated...wink 2

I'd need a lathe to enlarge the collet that fits in the folding prop cone thingamajig.

Folding prop collets/hubs are widely available and IIRC the blades are interchangeable. I have 12x6 blades on mine but obviously the actual diameter can vary slightly depending on the hub. Can't remember the current draw on mine but I get bored before a 2200 mAH 3S LiPo is anything like exhausted.

Trebor Have you got a drill press ? You could use that with a hand held drill or reamer.It wouldn't take much .

Geoff hat is one sweet motor

Oh I've had a bad experience with drills snatching on alloy, I always make a simple job a nightmare frown Been looking on HK website, found folding props but not the collet adaptors crying I find it very frustrating since the website updated.

This one on the HK site might suit a 5mm shaft. There are lots of blades but 12x8 would probably work OK

I can't see the motor spindle size listed for it !

Is my motor too small ?

What's the route measurment ? Is it the base of the prop blade.

I've measured my prop at 10" not sure what the pitch is and the base / route !! Measures 8mm with a 3mm screw through it. As you can tell this is my first powered glider with a folding prop so it's all a bit strange.

Sorry for long links the blade root is the width of the blade where the bolt goes through

I recently drilled out a motor collett about 1mm in a drill press but you do need to go steady and used plenty of WD40 as a lubricant.

Thanks for the advise, I found this one which Ive ordered. If I need to change the motor later on I can with the spare adaptors it comes with. yes

My lovely new spinner turned up but is it too big ?img_2675.jpg

The other thing my motor spindle is only poking through 9mm, I am tempted to file out the centre so the spinner can move back but are those slots in the metal disk for cooling ?

img_2676.jpg

Also the screws are slightly different diameter giving the props sloppy movement, has anyone filled and re drilled the holes before ?

Do you mean the prop pivot bolts on the new spinner are smaller than the old ones? If that’s the case then can’t you drill and tap the new holders?

I could but maybe the spinner supplied with the glider was a cheap thing. Before I do that I will check to see what other props require for a bolt size. The alloy spinner has 2.2mm bolts why are they all odd sizes angry
