Little Wasp

Here are a couple of Photo, of my air boat built from the plans that Boatmadman put on Mayem.

It out goes like a bat out of hell and pretty impressive on snow and ice too

Hi Alan,
Any chance you have a link to Boatmadman's plans on Mayhem I searched every which way and blowed if I can find then.
Cheers Damien.

Mmmmmm, they do seem to have vanished Damien but I will probably see him at the pond on Sunday and ask him what has happened to them, failing that I can measure mine up and redraw them.

Alan

Thanks Alan much appreciated.
This would be a touch of nostalgia the first model I ever built was a simple wedge airboat with a 2.5cc Tiapan glow motor in 1964 when I was 12yo.
No rudder just free run we steered it by lobbing rocks near it to cause ripples that upset straight travel and my brother on the other side of the pond to turn it back to me it was fun times selling newspapers to afford fuel and glow plug batteries anyone my age will remember the huge 1.5v dry batteries around 2.5-3" diameter and about 8-9" high with screw terminals I think they were mainly used as valve heaters in radios at the time.

Yes thats the thread Dekan but the drawing seems to have gone, well it's not showing on my puter anyway

Alan

you have to log in to see the drawings.
if you drop me a pm i can email them to you as i downloaded them a bit ago with the intentions of making one. unfortunately time has not allowed yet.
cheers

That will teach me to clear all the cookies, things happen to you like this when you get old, you wait and see Skalloway

There you are Damien, problem sorted

Alan

Thanks a lot chaps next project.
While thinking on this I remembered another air boat build I did basically 2 aircraft wings upside down skimmed the water using ground effect, from a drawing in Model Boats in the 60's or was it Popular mechanics so far back hard to remember.

Damien.

Bought a motor prop and Esc on ebay so the build has started.

good Damien, keep us up to date with the build. I suggest that you make the bow piece stronger, as these boats don't have brakes and take awhile to stop, if you get my drift

Alan

Hello Alan.
Finally comes the stupid question from Norway.
Is it not possible to reverse the motor? So that it will act as a brake.
Or will it cause the boat to become unmanageable?
Keep posting Damien Looks good
Regards Ole

I have that covered with hull covered with 6/10oz glass cloth and polyester resin I will also do the bow piece from 1/4 grain balsa.
Please don't expect the build to progress quickly I doubt it will get it's bum wet before Christmas

Christmas, think you need to get up earlier in the morning Damien

Nice to see/post with you again Ole, I think you can get brushless speed controllers that will give you revers but I have never had one. Most people would probably not need one, it's just me that's a bad driver



Alan

Thank you Alan and the same to you.
In other words, to drive such a vessel, you must plan well in advance. You do not take a trip to the pool when the mother duck is out with the little feather balls for the first time. Do not think you're a bad captain Alan.
regards Ole

I'm OK with most of my boats but if I put the air boat or the springer on the pond, everyone else takes their boats out of the pond


Alan

Excuse me while I laugh Alan. I have a picture in my head of you who show up at the dam. and people and animals running in the opposite direction.
That is all it takes to get a grown man to consider knitting.
Ole

I'm thinking along the lines of 1/4" triangle on outer edge of hull bottom (Not sure nof the nautical term) to try to deal with the quite severe drift.

It's the severe drift that is the fun, just my thoughts but putting those bits on could help to flip it, they are a bit prone to it, so keep your motor as low as possible, (smaller prop, bigger pitch).

On the flipping side, the brushless motor does work under water, but the ESC starts to smoke

Been there, done it, bought the new ESC


Alan

Can imagine that it all was quite realistic when it began to smoke Alan.
And the temperature in your head also approached the smoking stage.
It was good that you had to swim to retrieve the little wasp.
Water has a cooling effect.
Ole

Sorry.

No swiming for me Ole, we have a chap in our club thats into rubber, he can't wait to get the waders on.




Alan

We are talking about the same club?
Or for that matter the same hobby?

hehehe

Ole

Purchased on ebay a 7" Aquaman figure for the driver of my Airboat seemed rather fitting when I was trolling ebay for appropriate drivers.

I wanted a figure to go on my little wasp, but couldnt find one brave enough





Alan

When I was a little boy. (a few years ago) there was a character named Lone Ranger.
He was after that I can remember very brave. And you could bend his arms and legs as you wanted.

Ole

Aquaman has moveable arms and legs and a trident staff which I intend to integrate with the rudder servo.

Sounds like that Aquaman is the right man for the job.
ole

perfect man if I accidently flip it over lol

Yes it is Damien. And not only that. You know an air boat upside down is a normal boat, the propeller is under water. Good then to have a captain with the right equipment.
Ole

Well Christmas and new year have been and gone the boatmadman's plan has been modified to a slight V bow.
Seems we have a lovely big lake but Ballarat is the high point of the central highlands nowt but several hundred kms to stop the south westerlies off the southern ocean good sailing days are few and far between I have made 2 motor mounts building 1 for Jo as well, I'm waiting on the second motor and ESC from Hobbyking . Ill be able to use the weeded up more protected sections of the lake with airboats we'll pretend the bird life is gaters
More later.
