Assembly: Aeroworks QB 150cc Yak 55M

Well... I was looking at the access hatch on the top of the motorbox and thinking how I'd prefer that area solid. So I took out the screws and epoxied the hatch in place. Then I covered the top of the motorbox for fun. After that I finally quit screwing around, haha, and got down to doing some standard assembly items.

I mounted the ignition (leaving an 1/8" gap underneath most of it for air circulation). You can see a couple of extra leads coming from the ignition. Those are for an optional LED light and an optional tachometer.

Next I installed the fuel dot. I had a couple of other fuel dots laying around (and there are several nice ones out there these days), but I chose the JEModel fuel dot that Aeroworks sells because it's smaller. And, with the round fuse any large flat plate bolted to it is not going to look very good. I made this backing donut for it, because the sides of the fuse are balsa.

I made some hard points for the Fromeco Badger switch, as well:

After that I mounted the ignition battery.

I have always used "nasa" foam, but have been reading that it hardens in cold temps. It's pretty mild here in California, but I thought I'd go with DUBRO foam from now on.

I've always soldered on Ultra DEANs to the battery leads. I never worry about them coming loose. But, in this case I thought I'd try the Aeroworks Safety Clips:

In this pic you can see the engine mounting bolts. I epoxied the blind nuts in place. Then used blue thread locker on the blind nuts. Then blue thread locker on the standard nuts. Then blue thread locker again on the nylon insert lock nuts.

As you can see in these pics I plumbed up the PSP Manufacturing fuel tank. I like to use 1/8" line to the fuel dot (so it doesn't start getting loose), and 5/16 line to the carb. DA says 1/8" is all you need with this size motor, but I've always used 1/8" for 100cc and 5/16" for 150cc. I'm going to be a creature of habit here, and do what I've always done. haha

Aeroworks has these vent dots, so I thought I would try one. I didn't attach it with CA like its manual shows. I used epoxy in hopes of having it be maintenance free.
