HPR 010 Mono: Very Slow Build

[iridebikes247]

Very nice work, everything looks good.

Looking good.

Not much done. The rudder seems to be lost... It made it from Germany to the US in one day, took a day to clear customs, and has been mia for four days...

Aside from that, I will split the inner backing plate for the main drive mounts.

Now I just have to make the side plates. I want to make them out of 4mm carbon.

That looks like a great mount. Going good sir!

Here is the new motor mount face. As much as I really like the old style, the new one actually looks pretty good. It's a lot prettier in person than in CAD. The overall quality of the cut is significantly better too. It is a little heavier, 39.6g vs 37.7g. I also cut it with a vertical grain instead of horizontal like the old one.

I wanted to make the side drill jig, but my buddies called me to play a game... That will happen tomorrow.

What's wierd is that my plunge/drill operations do not go all the way through unless I exagerate the depth. In normally leaves a slight skin which you can see in the picture.

The first set of holes was me being stupid. I didn't zero the x a is to a good location. The design was hanging 2mm off of the material.

I really would like to build a vibrating/tumble polisher, then have the parts anodized, but that's a bit more than I want to do at this given moment.

Yes I understand. That's why I had it as "1850kv". It's just a typo on the site. Thank you again though.

careful if you ordered the 3730-3 it has 1580 KV

check the manufacturer spec

The mount is slowly evolving. That's the good thing about being able to make parts yourself. If the overall idea shifts, you can just make new parts. I brought the side bolts closer together (24mm to 16mm) due to possible clearance issues. The inner hole was increased from 13mm to 18mm to accommodate even larger thrust bearings for 6mm shafts. I replaced the cooling vents with another set of mounting holes. This will allow the motor to be clocked at 45 degree intervals instead of just 90. I also do not like the idea of only using two bolts, so I kept all four. I also made the angle adjustable from 10 to 30 degrees. That should be plenty.

I would like to play around with the idea of water cooling the entire circle instead of just the top edge like all of the other cheesy mounts. The unfortunate part is that it would compromise the overall strength of the mount. The only reason I went with 1/4" was to allow for the use of m4 side bolts.

The motors you see are the FC3730 (larger outrunner), 4082 with a 60mm long jacket, and the smaller HF500 (closer to the Scorpion's size). For reference, the mount with the twin outrunners have 3/16" side plates, while the inrunner/outrunner mount has 1/8" side plates.

As I was making this post, I came up with the last design. No water cooling, but a lot of through holes. It shouldn't compromise strength at all. I can also bevel the edges on one side. (I don't really want to try a two sided bevel again with this machine.)

Thanks!

Man that sight is so sketchy, but I went ahead and ordered the "1850kv". I have no idea how long it will take, but I'm in no rush. The motors were originally $45 each from FC, but the total was $65 ($25 for shipping).

Any advice on what filler to use to fix the exterior of the hull? I'm scared of it just peeling away.

Axel and I were talking on the side and he made a suggestion to use an outrunner to save weight. I do like the idea of an overall lighter build. He initially suggested the Scorpion 2300kv Watercooled on 5s. I want to stay on 6s though. There really aren't too many options though. I've narrowed it down to the Gartt HF500 1600kv (<favored) and the Turnigy T600 1400kv. I can't find the Suppo/Fightercat 3730 1580kv anywhere. I sent Jason (Fightercat) a message.

I didn't even think about that, but who would put a flood chamber on a boat like this?

Somebody who want to race the boat in Europe or someone who wants the boat to self right

Man that is slick, nice job on planning it out.
