Dumas Hawk 3.5 new build FE Conversion

[capnswanny]

Here's a cruddy video of my second "first" run a couple years back, with commentary provided by my son and the rest of the crew on the lake. I never fixed the hopping problem, and I took on some water knocking out the RX, but you get the idea

I thought I was gonna have to cut that bulkhead and mount the motor like you did. I waited till I had all the hardware mounted and batteries in it and found CoG just slightly behind sponsons and that's it...

Man, that's looking great!
I like how far forward you mounted your motor, I think that will get the cog where it should be.
I picked one up at a hobby show and converted from nitro to FE. This was my first "real" FE boat and I struggled a bit too get it to run well. My cog is still father aft than I would like and there's a lot of extra weight from the original build. I managed to squeeze out 38 mph with a AQ2030, AQ60A ESC on 4S. Got 43mph with the AQ1800, Seaking 120 on 5S. Here are some pictures I snapped for you tonight with a 5S 4000 battery in the hole:

I splurged and bought a quart of automotive urethane clear and I'll never point a rattle can at a boat ever again... This Urethane is amazing stuff I used three ounces of clear and reduced by 40% and it was perfect consistency for my airbrush came out cherry still looks wet and its been dry for a day now

what size prop did you run

This run was a m447.

That boat should run well with starting off with an H4, H5, and if temps OK H7. All in that order. With a high RPM .21 sized motor it will push that hull into the high 60's They are sweet driving hull once set up correctly. Mine is 8 years old and can still hold its own, but I run it with nitro power.

Right now for starters I'm gonna run an AQ 2030KV motor and I'm starting with a Graupner K Series 42mm and I also have what is equivalent to an Andy Brown 1450 and a m445 and I can tune a prop to the boat... So I'll get up there eventually. I have plenty of room for Lipos and the next size up in motors but I think this will make a good PLtd hull.

Putting the finishing touches on this project... I need to fasten the receiver battery in position and build the flex and stub shaft assembly

Well I finally got to the lake this morning and I recorded the Maiden Voyage and she ran pretty good and the temps were cold so I have room for more prop!!! I was running a Graupner K Series 42mm prop 2 2S 5000mah dinogys. I'm gonna order some more Lipos I only have one pair. I'm thinking about the 6000mah 2s dinogys.
