How to mount power pack c motor on explorer

#1
Hey everyone, I’m new to rc airplanes and the flite test explorer is my first one. I am still building it but i am confused on how to mount the motor. I have the power pack c. Thanks!

Edit: i just went through the video again and found that after they mounted everything they showed how to do it with the power pack c. However, i am missing a part that i believe was supposed to come with the motor. As soon as i opens the box, i noticed there was a slot missing something but i didnt think it was important. Now i realize it is. I think I’m missing the prop collar.

If you have the new radial C-pack motor I'm not too sure. Your only option is to mount it like the B-pack instructions say in the build vid but follow the height recommendations portion for the C-pack and make sure you have prop clearance before gluing. The old 2215 motors in the C-packs could be mounted on both ends but not the new ones. The empty round spot in the package would normally be for the prop adaptor but the radial motors use a lock nut and the prop mounts directly onto the shaft so no special adaptor is needed. You should have an X mount base and a bag of mounting hardware in the package.

So i ended up mounting it like this (picture below), but now the props dont even screw onto it. I’m new to rc airplanes and stuff but I fly drones and the props usually screw into the motor. Am i doing something wrong? Also is the way i mounted it ok? Thanks :)

The props in the packs are a really snug fit on the shaft. I had to do a little scraping on one yesterday to get it to fit, just have to be careful not to scrape too much.

The nut holds the prop on and will secure it against the body of the motor. Albeit tight the prop just slides onto the shaft. If you have any 8 or 9 inch props for the drones you may think about or have to0 give one of them a trial fit. They have changed the prop sizes in the kits since that build video was made and the 10 inch ones in the current C-pack kit may not work on that plane. I can confirm that the 9 inch prop in the current B-packs will not work with the motor mount in the lower mounting position.

It's a nylock nut, you will have to use a 10mm wrench too finish tightening it. You will just have to do a trial fit with that prop and see how it goes. I do wish they would update the build vids for the planes that are affected by the parts changes in the packs.

If you have the props with a build in nut, like on the Phantom, those will work also.
Provided it fits and th threads match.

Here is mine. Note the ends of the prop. I used a lathe with a pen vice and centering tool to secure the prop and my trusty stick with abrasive paper glued it to both balance and size it. That's a B-pack motor with the 9 inch prop supplied in the kit.

Here is how i ended up mounting it. Also, the propeller is too large and hits the body. How do i trim it?

But the way i have mounted the prop on is ok right?
Remove the extra spacers that are between the prop and motor (keeping only the correct size spacer in the prop itself), and tighten the nut completely against the prop. There should be threads from the shaft exposed beyond the nut.
