Great idea! Thanks for sharing this video Andrew!
Great design !!!, perhaps adding a Pool Noodle wrapped 45 degree elbow on the front of the PVC pontoon would help with maneuvering and stability sort of like a ski profile. The next challenge will be actually retrieving a plane, I used to fly water planes back in the 80's and figuring out how to get the planes back to shore was a lot harder than we all thought it would be, we spent many weeks revising designs, because the "stranded" plane has it own idea on direction and hydrodynamics when it's pushed or pulled, but then that's half of the fun of this hobby....engineering.
The designing building and modding are a major part of the fun, maybe the biggest part.
Great vessel. Innovative. Especially the reverse, with the middle propeller.
Thanks, here's the real deal with lifts as well - ruclips.net/video/-Z70ChdFL50/видео.html
Great fun just on it's own. Waiting to see actual rescue in action. Thanks again for a new slant on our hobby.
Yes you're right. I'll have to try at least one mock rescue
Great video .. any chance you can test it in the ocean with the fpv 😀👌
Unfortunately no, it has been decommissioned for other projects.
Well that seems to work quite well! Looks kind of fun to just drive around!
Certainly is.
Looking good.. Try angling the motor down so that they push the back of the craft down and so lifting the front out of the water more. From what I can see in the video the motors are pointing up which will add to the noise diving. For the front take off the bottles and cut a 45 degree slope and reinforce it with coroplast.... Brilliant cheap craft for all sorts of applications..
This one is my FAV, love those camera shots! outstanding!!
Yes I agree. Those low level shots look cool
Swwwwwweeeeet !! I love it. Great rescue boat.
I have wanted to do something like this for a while . I thought of using a solenoid switch to reverse the leads to give it reverse . I was thinking more like a airboat with rudder flaps but after watching this two motors may work better . With each side having reverse it would be very maneuverable . Thanks for the new inspiration .
Yes that's the best solution.
Would prop efficiency come into play when the motor spins in reverse? If "reverse gear" was just to back out of a problem then maybe it'd be enough. It's interesting. I gotta think more on that.
You can get reversible ESCs now. Not even surface ESCs, but re-programmed generic heli ESCs. The ones I saw were meant to be used in battlebots.
Absolutely brilliant Andrew, the only thing I would have done different is the pontoons. I would have tried 40 or 50mm PVC pipe with T pieces and reducing bushes for the smaller pipe (eliminating the pool noodle) and used the gas gun to bend them banana shape (or use 45 degree bends) and use end caps. Should solve the splash problem.
I'd try a bit of silicon in the bike tubes to hopefully seal the ESC's better just in case it ever did go over.
Good ideas Ken, work in progress.
Awesome project! I've been thinking what to do with some extra motors and escs, and I think I have my answer. Fan boat! It's extremely manuverable with three motors and no rudder. Impressive!
Easy build and lots of fun
Great build Andrew, I just can't help asking myself that if I need a rescue boat do I really want a seaplane in the first place at all? 😊
Chris you are so right. The boat is enough fun by itself.
Moving the CG aft would help keep the nose from diving. I will probably duplicate your design when you get it dialed in. Good job!
Excellent Jim, look forward to seeing your version.
The motor you change the forward to reverse to go forward
Very nice. The motors appear to be angled downward a few degrees which looks like it is pushing the front down under power. A regular boat having the propeller underneath means that power will tend to tip the front up. My guess is that if you angled the motors upward more (ie. a lot, like 30 degrees) you wouldn't need to alter the front tip of the pontoons, but sounds like you have already done that :)
Yes the altered bows made all the difference
i would make the poolnudels more aquadynamic :)
Im sure this would make the boot much more stabel and also the boot would glide on the water !
Yes I want to get it planing
Necessity is the...
Nice one!
Might not even rescue anything, it's great fun by itself
an absolute joy to watch your videos Andrew love the idea of more projects with this boat perhaps some wings to make it an ekranoplan
I'll at least try to get it plane-ing on top of the water.
I'm also thinking of FPV and maybe towed underwater camera
+Andrew Newton laughed out loud at the plane-ing I really like the towed fpv idea
What a cool creation! Now you just have to modify the floats for more speed hehe... :)
Yes I have heaps more thrust available, needs planing hulls
fantastic, loved this episode!
Thanks Neil
I recon taking the bottles off the front would improve the water flow so it doesn’t splash, either bending the pvc pipe or putting a smoother point on the pool noddle would be good
Yes that is what I did
a set of tundra sea floates would be ideal for your craft
Surprisingly entertaining.
Surprisingly fun
I've been looking forward to this video Andrew. You didn't fail to entertain with a very unique build, I see you're already modding it so that'll be fun to see. My grandchildren have given me 'that' look so looks like I'm back in the shed too!
Any excuse to go back to the shed. Glad you (and your grandkids) liked it.
nice nice just watchout for bigger boats :D:D:D
Oh yes, might have been able to save yours
your vid did make me wane build a new and bigger one thx
good job you have to make the front like skis for less splashing
Done
Well Done Andrew!!!!....Wonder how it would work as a "Snow Skimmer"????
Definitely, using plastic bottle instead of noodles
I think it would be pretty good to put 45 degrees elbows on each front end of the floating things so that the water doesn´t splash so hard when you accelerate.
Update video coming soon
that works great.
Even better with bent up bows.
Super idea.
Cheap and easy build too
Clever design..
Thanks, don't know if it will retrieve a plane yet.
this is genius!!
or madness
Hi Andrew,is it possible to give a scheme how to fit the esc ‘s on the receiver
Why not waterproof the ESCs by ceiling the end of the bike tube with hot glue or silicone?
Yes that would be the permanent solution, this is just the prototype
or even put them in the box
Yes. I just pulled apart a tricopter and used the ESCs without rewiring.
plasti dip is a good for waterproofing an esc and other stuff
Must get some
I think a better bow shape will improve performance, angle the motors, the same way you would for a plane, to counteract the bow's movement under throttle.
Was that the Warrnambool train?
Could have been, or just a Marshall or Warne Ponds train. Better bow shape has worked well. Video soon.
Hi Andrew, great rescue boat, how did you run all three motors on the one transmitter with three esc's ?
Yes three escs, three separate channels
ok thanks
Any plans for an rc crane?
Getting serious, I'll just have fun buzzing around for the moment. We dont have good seaplane sites really.
What about the esc programming you promised? Please.
I have done it. Search
how did you fasten the bottles to the pvc pipe?
Might have just forced them on, but it was much better with bent up bows and a flat wedge cut in the foam
Put hydrofoils on it to lift the nose (and entire boat) for rapid deployment.
I so want to
i made one with 2 boat esc has reverse steer like a tank left and right stick forward for forward both sticks back for reverse can pivot in place
Yes that would be ideal
$5 tube of GE silicone and every model you have will be waterproof
but can it slope? ;)
Hmmm, might struggle
You're certainly nothing if not an ingenious make do and mend character (that's a compliment btw)
When I was racing 1 metre RC yachts the hull was mostly underwater in a breeze and we rarely got problems with water in the electronics which were (mostly) hidden away in screw top plastic pots but the necessary wire exits were barely waterproof. That was in the days of VHF 27Mhz radio so yours looks pretty foolproof. We certainly had to drain the hulls after each race.
I thought at first you had managed to reverse the B/L motors for astern operation until I saw the extra prop in the middle. A great solution. Presumably you've done a mix to the rudder (or aileron?) control to the other two motors for steering. I'm surprised at how effective that is. Those cheapo twin prop foamie 'planes are pretty poor at turning.
I'm disappointed at your lack of confidence and moral fibre when you opted for a piece of string on the maiden voyage! Come on you antipodeans are more than that! btw is your pond a former clay pit? From the works chimneys in the background it seems possible.
Thanks for the entertainment!
Great comment, and you will be happy to know I have not since attached the tether. Although it might be one of the rescue options. The waterway is a little side pond on the Barwon River which cuts through Geelong then exits to the sea at Barwon Heads. The brick chimneys might belong to the old wool scouring plant.
How did your program the motors to run that way?
Watch the mixing video
HELLO Andrew can you send me set up for Taranis please
Here's the link drive.google.com/file/d/1lc1KDcTOJCl_ANqFyX2Gkkcf5OwFJp-5/view?usp=share_link
www.cxndesigns.com/airboat.html I found these a while back, looking for pan/tilts. Rescue 1 looks like a lot of fun
how about side thrusters for strafing? :D
Ha yes I did consider them
Any crocs in that river? ;-)
We're about 2000km south of where crocs are found, introduced pest carp are the only issue here.
may we work at an idea?
Yes
