S9tim's 80100 direct drive


#82

I kept the original bearings for the first 20 runs or so then switched to sealed bearings (which are not sealed). I just change them out every 20 runs or so. None have failed yet, just get louder with time.

I have not added a thrust bearing.

Nice setup! What lipos are you using? I’m trying to source some but am not having success with hobby king.


#84

I am using a brand from china found on ebay. They are 6s 10000mah taotuo batteries. They have held up very well so far.


#85

Ok I want to buy a 80100 motor to join everybody else! Haha. The problems I’ve had with the gearbox setup has been ridiculous. @s9tim is this the motor you have?

I saw a few with the same 80100 model number.


#86

Yes that is the same motor. The other one you see probably is a sensored motor which we do not need for our use.

Even though it is back ordered it usually ships in a week or two once you place the order.


#87

Hi there are the coils coated with epoxy?
Thanks.


#88

No coating on the coils. I only epoxied between the magnets.


#89

The prop looks like it will cut you in half if you fall wrong. Does anybody have plans for covering it? Would be nice to hear about efficiencies lost with a duct on such a big prop.

Also, has anybody had success putting the 100kv APS 6384 PowerGlide motor with a duct on a foil board? I would love to know battery life because I am hoping to get up toward an hour of run time.


#90

@s9tim awesome job!
I would like to ask you if you cut the motor shaft by yourself or you order the motor whit a custom shaft as you required?


#91

I cut it myself with a dremel tool and cutoff wheel.


#92

I made a hands free flush adapter for my APS 80100. I can hook it to the hose and it flushes the motor with fresh water while I tend to the batteries, etc. I will add the file tomorrow.


#93

now that’s a cool idea.

do you spray the motor with wd40 or some form of oil to keep the bearings from rusting


#94

I soak it in a bath of corrosion x about every 6 runs or so.


#95

Usually ducts help to increase the efficiency. Helps to prevent tip vortexes. But if the ducts cross sectional area is too big you might get a lot of drag.
