Here's the rest of my saucer fleet.

Here are some photos of my saucer 40" saucer and the removable motor mounts for it.

I have a 40" saucer that is yet to fly. I would love to certify level 3 with it, but was told that a nose cone was needed.

I agree that the plastic hubcap should work well. I wonder if more spokes like that actually provides more aerobraking than a traditional saucer by causing more turbulance in the airflow?

Could copper foil tape be used for wiring? Like this one: https://www.amazon.com/JVCC-CFL-5CA-Copper-Conductive-Adhesive/dp/B000UZ8SJK Maybe run this foil tape on the outside and cover it over a layer of fiberglass or carbon fiber?

Would you mind posting a picture of it? I wouldn't mind making one for myself. Thanks, Mike

I decided to take some more detailed photos, so I borrowed my dad's Nikon D300 with 18-200mm lens. Here's a close-up of the forward end with the 5 x 54mm MMT. I filled in the gaps with thickened West System epoxy. The electronics bay with the hatch removed to show the sled. The LED...

I've constructed some MMT's for 75mm and 98mm motors using 5-minute epoxy. Will this be a problem? Or should I add a filet of West System with thickener? A photo of the MMT's:

You want the CG to be far enough forward, though, that the saucer aerobrakes properly. Saucers can come in tumbling and land on edge causing some damage. Also, I think it's almost impossible for a saucer to come in ballistic because of their shape.

Everything is done. I just have some work to do on the parachutes and shock cord, which I'll do in another month or so when I've got more money to work with. Here's a video of all the lights in action. I hope I got it right this time! pRHrag-gAZI

Alright, got all the motor mounts sanded to fit. Also finished soldering the remaining lights. I'll have to get a video sometime soon. The weight with the 98mm mount in place is 9.6 pounds. I hope that's light enough to fly the M650 someday when I've got my level 3 certification.

Seems it was lighter than expected because I forgot to add the weight of the motor mount(s), which don't fit! The central body tube got a bit distorted. The motor mounts just need to be sanded a bit.

Just weighed the saucer via a handheld luggage scale and it came to 8.4 pounds. This is lighter than I expected. I'm guessing the electronics and parachutes will add about pound or so.

Here are a couple of post vacuum photos. You can see that I pulled a tad too much vacuum and that caused some wrinkling in the disc, but it's not bad in my opinion. I just have to do a little bit more soldering then I'm done! I just hope I can launch it this October or November.

I had to order a new vacuum bag, because the old one had too many pinprick holes in it. It arrived yesterday and today had a friend come help me apply the epoxy and get it all in the bag. It didn't take much vacuum to get the two halves together with enough pressure. Here's a photo of the saucer...

Yeah I'm an electrical engineering major at CSUN. Sounds like you are a student there too.

I have no idea when I'll be able to fly it. I've got two more payments to make for the fall semester and then there's the books. Engineering books are expensive. October or November do look like good possibilities. My first flight will be a day flight on something like an L1150R, L1300R, or...

Ah great thanks for the tip. Mike

Yeah I know. This is my first time posting to YouTube and I have no idea how to do it. Ah well. The lights look great! Take my word for it! :D

Alright hope this works: https://www.youtube.com/watch?v=jLPgo9ZVC0A
