Canada. I am in the States and have bought two 40.160s from them so far. No complaints.

OK.
I have the MGM 25035 z-series and so far no problem. I definately agree to buy a good one from the start instead of messing around.

I use this stuff. A LOT cheaper and works great.

There are E series, and Z series ESCs. I'm running either 6S1P or 6S2P sport run setup with atleast 50+ mph range. So which esc would work with Neu 1521 1.5y.

This guy on Youtube is running with a NEU 1521 1y, prop M445, 6S2P. I''m wondering which esc he is running with. Check out the video.

This guy is running KB45 1200rpm, Turnigy 100amp HV. (I have a brand new Turnigy 100amp HV 2-12 Lipo , and Pistix)

Tony, not sure where you are, but most auto parts stores have a 'body repair' section. They usually have fiberglass cloth. You are much better off, however, using carbon fiber cloth. Expensive but worth it!

Found one. Will this do?

The E and Z series have the same particulars, the only difference is that the Z-series is compatible with the black box (better to use eagle tree).
If you are running 6s for me it is better to have an ESC rated for 8s. Please read this (takes some time)

Do not believe what you see in youtube or even here sometimes. Maybe the setup runs great for 2-3 times and then takes video etc.. but when the damage happens in the next run nobody knows it.

The 1521 1.5 Y is 1050kv, on 22.2V , 23,000 rpm theoretical. Seem a bit low for the 50mph range. I do not know this hull very much maybe somebody will come in.

Found this in RRR, NEU 1521 1.5y, 8s2p, 442 Turnigy 100amp HV 2-12 Lipo . Better to contact him, if this setup is OK you can use your ESC and get the rest.

NEU 1521 1.5y is out of stock. OSE has 1521 1y in stock at the moment.
Thanks for the link.

I have a cat that I had FDM assemble. After looking at your pics I took a look at mine.
The JB weld was starting to lift from the hull. So I sanded the whole area and took some epoxy and fiberglassed the whole thing down. Your mishap just prevented me from having one. Just wished you had of caught yours before this happened.

I would have sand it off and epoxy the mount area had i known JB weld was just junk. Anyways, what epoxy and fiberglass are you using?

[domwilson]

Fine weave glass and 30 min epoxy. Feels real solid now. Tried pulling the mount. It's stuck in there real good now. I think if I tried to pull it out, I'd probably break the hull.

The JB Weld is probably good stuff in it's own right. What I suspect is the cause of the weld breaking away from the hull is zero preparation by the builder.
When epoxy resin cures there's a chemical (I can't remember the name) that rises to the surface & is sort of like a wax or sheen. This needs to be removed before over coating with more epoxy resin or adhesives. All that is required is a scotchbright pad & hot water. Make sure it is dried completely(hairdrier) before overcoating or glueing. I also then wipe it with a cloth dipped in acetone first.
I also do the same procedure with polyester resins too.
Cheers.

If you want maximum adhesion with JBweld once its mixed and setting in the boat heat it with a hair drier to about 175 to 200 degree's . It turns to a watery consistancy and absorbs a lot better into the hull below . the bond will be way stronger
