My Micro Hydro

[J Solinger]

I wonder if strategicly glueing some carbon fiber strips in the top and bottom would stiffen it up enough to forgo the wood frames?

[JimClark]

Doc and Randy just how much framing does on of these little babies actually need? I plan on filling the sponson's with foam and adding fiberglass to the inside of the tunnel area. What about supporting the deck?

I ordered a bunch of wood from national balsa last night. I could call them and see if they would add some more 1/8 lite ply for you then send it to you if you want. The $25.00 min order is what kills you

Thanks, I appreciate it.

Doc, what kind of ply are the MH frames cut from?

I guess I know what I am doing tonight!

Where did I put those notecards...

[RandyatBBY]

When making the templates use Medical Paper tape to hild the 1/2 together it will pull off with out ripping the card stock apart.

[Sneasle]

Sounds like a plan.

[Dr. Jet]

Think the 2700kv will give me any difficulties?

No. You may even consider going 3S with a 2700 Kv motor and a small prop like an X427 for starters.

[Sneasle]

hmm. ok, I will go with the 30amp super simple from HC then. I've used them in planes and had good results.

Think the 2700kv will give me any difficulties?

[Dr. Jet]

Can anyone give me some input on what size range props I can expect to use and how much current I expect to draw?

My hulls are drawing somewhere around 10~12 amps with a 29 mm Graupner prop and the 3000 Kv motor.

@ Jim

Well, Doc did such a good job cutting the lightening hole that we can't really do much modification to those frames. I might just use them as a template to start from, the only problem being I can't get the same type of lite ply used for those frames locally. I'll either have to use a stiffer ply, or go to balsa, so I'm not sure what to do since I want these boats to be as equal as possible.

@Randy

Good to know. I'll get a set on the way.

Can anyone give me some input on what size range props I can expect to use and how much current I expect to draw? I can mentally size my power systems for my planes pretty easily.. boats are another matter and I have no idea how big of an ESC I'm going to need.

[Dr. Jet]

The hard part is getting the top of the frames to fit. maybe Dr Jett has a trick up his sleeve on how to do that.

Jim, et. al.,

Here’s how I made the outline for the MTH framework: Using card stock, I made ½ templates; one for the top and one for the bottom. It was mostly trial-and-error cutting, taping, splicing, and fitting. Once I had the proper outline for the top of the frame and the bottom, I lightly “tack”-taped them to the hull pieces and assembled the top to the bottom. Then, through the hatch opening, I taped the two half-templates together with the hull halves joined. Voilá, you now have a perfect-sized template! Then use this template to cut out your reinforcement pieces. This works for the stringers as well as the bulkheads.

[RandyatBBY]

no worries, I'm a slow worker as well.

Anyone got any comments on that motor?

It looks like a good choice with Lipo. I think I want to try one, but I have way too much to do.

It might take me a little while. I just ordered some wood and fiberglass so I probably wont have anything for a week at least.
