I've decided to build your model. The structure is already build :) The only thing I can't make is the metal part :/ So I'm thinking of using balsa instead.. Do you think it'll be ok ? I think it will be strong enough to support the motor but I'm afraid the weight will be not enough.

scale doesn't matter, you can make 100-200% or whatever you want. Use a brushless motor, it is not afraid of water

Hey There Brother. Nice work on that boat. I do have a question though. What kind of tape are you using there and what kind of heat are you applying to it? That's a seal the tape to the styrofoam? What kind of tape is that it looks almost transparent or translucent. Thank you

[@NumaVIG]

it is ordinary packing tape, heating is selected experimentally (I think no more 120 °C)

[@nategameing5491]

Dang it went fast

[@chasinelwood1977]

So, me and my son have completed a slightly modified version of this boat and yes, it is very fast for such a small motor. Its speed is due to the lightweight nature of the boat itself. The thing is almost weightless in your hand whenever you first build it. The only real weight is associated with the batteries motor Etc. Basically all the electronics. I would highly encourage anyone who's thinking about building one of these to build it. It works well. I will post my version of this boat here soon. Great job do the inventor my hat's off to you

[@mpikas]

I hope someone tells me otherwise but I don't believe that we have any equivalent to that glue here in the United States. For that matter, I've watched a few of your videos in the last couple of days and I don't believe we have a common source (someplace we can just walk in and grab some) for Depron or anywhere near the selection of foam at anything close to those prices. Some of us can get Adam's rediboard (we used to call the stuff "foam core" when I was a kid), but that's paper faced and MUCH heavier, and if you strip the paper it's still heavier and it curls up (not that it's all that flat to start with). At the hardware store, we can get much thicker insulation foam (about $33/sheet here), the fanfold foam that people used to use is pretty much gone (and was much more expensive, I believe something like $60/pack, I've never actually seen it, I was just told they could order it and get in a week), and IF you can get something at your local craft or hobby store it's MUCH more expensive (looks like 10-20x).

I am quite impressed with you little boat and your building techniques. I would not have expected that kind of speed from your power system. My only disappointment was the paperclip pushrod. Your boat deserves proper linkage oh well it works anyhow and quite well.

So I have a question. I have a 1000 kv airplane motor with a ten inch prop. And I built a simple flat bottom boat about 7 inches wide and 3 feet long. Does anyone think that will be to much thrust.

[@ernieu4]

Only one way to find out lol

[@larrywhalen127]

Samuel, this is where your throttle setting comes in handy, run it as fast as you can on a calm day till it starts to become light at the bow and then mark the setting, then use about 10% less power when the wind increases in speed. You could also mount a canard or stabiliser on the nose to negate lift, by starting with 2.5 degrees negative and increase as necessary from there until you are satisfied with it's performance at whatever speed you decide to be the maximum you are comfortable with. Or even add a few ounces of lead at the bow to give it a little more weight in order to help keep the nose down. So there are a few options, with throttle settings being the most simple.

[@Raycefan]

I’m curious, could I use hot glue instead of epoxy? If so, why did you choose epoxy rather than hot glue? If not, why?

[@NumaVIG]

hot glue too fast

Like TJ´s films, I thought the motor that you used looked a little small - but I was very wrong! I liked the very lightweight hull design and the way you used the covering material as a hinge for the rudder, too. Thumbs up : )

I made it finally. Numavig has some serious taping skills. I could not manage a decent job so painted in acrylic and wiped polyurethane over it. I added a brushless Turnigy with 1000mah 3s. It’s really too heavy so had to adjust battery placement further back in the next compartment. The prop yaw is way to much. I have even rudder deflection but no authority when trying to turn left😢. It hasn’t been run in water yet just on the grass and it does indeed scoot along nicely on grass (so long as I don’t need to turn left). Had to trim the rudder a tad above the bottom of the hull for this to work though. I’m not sure how to fix my problem but…. Thanks for the plans and am interesting build!!!
