So, I started my tricopter build today. Want to say it is my first RC anything other than the kids stuff when I was little, a glider that never worked, a minirobot, some airsoft guns right out of college, and a lawnmower.
I picked up DT700 motors because everything else in the DT range was out of stock except the DT850s which were not specified if brush less or not and I am assuming the differences in the 700 and 750 as used in the tricopter guide are minimal.
I got to the part where you put a bit of epoxy on the motor to secure the wire. Apparently, I had an issue with the nozzle of the two parts and what I thought was the right consistency was not.
On the first motor the thinner half of the liquid squished around the wires and between the magnets. Not a big deal because this must have been the drying agent and dried quickly without leaving residue. The second motor was more of a problem. This time the goo flowed between the magnets and actually began to harden. I quickly took the motor apart. The third motor was fine and still appears to be fine. The first motor seems fine like the third one.
When I took the motor apart I used a paper towel with mineral spirits to wipe both surfaces of the magnets together as listed under cleanup for the glue. This did absolutely nothing for the glue other than make bits of paper towel stick to the magnet surfaces. What crap.
Well the stuff is still semi sticky. Seems that it is actually 25minute - 24hour glue as listed on the back instead of 5 minute as listed on the front. I have peeled the papertowel off but there are still tiny globs of sticky glue on the magnets. I assume that when it dries I can scrape it off. As of right now when I insert the motor back together it is harder to turn when I turn it, imagine that.
Here is my question, how screwed am I. I dont remember too terribly much about motors from school many years ago other than this type takes three wires to make work. Kind of like the three phases of power produced by the big turbines at power plants. Assuming I can get the maginets clean will the thinner epoxy that is covering some of the weaves, maybe on one or two columns, screw me over. Also, is it even reasonable to think I can get enough of the epoxy off without damaging the magnets to make the thing work right again?
I know I regretted not getting DT850 after I determined they were bigger versions of the DT700s which officially support 4 cell lipo but I didnt want to have to buy new ones already. So, am I screwed???
