Flying on Water

[Chris Fretz]

Anyone ever try flying in the middle of a fairly shallow Creek or River? Do you think you could stunt with pontoons?

[Dane Martin]

That is something I've wanted to try also. I wanted to get this kit from hobby people to try it out by converting it to CL. Also, from my rc days, I know you can spray pam on the pontoons and fly off grass just as easy!

We can do this  I wanted to slap some pontoons on a beat up Estes Ringmaster an try it. Just don't know where to get some cheap light pontoons.

Wow that thing is big, I guess if your going to do it go all out right!

[Dane Martin]

I like big planes! Lol
How about some light foam pontoons for a ringmaster?

Do you think these cheaper ones are big enough?  http://www.ebay.com/itm/291250624878

Back around 2000 at the NW Regionals (roseburg, Oregon) there was a CL float pond created and we hosted several events at the site. It was a 180 degree arc of water and we flew everything from large CL scale models to stunt models with floats. We even flew 1/2a models with floats and then my 80" Piper cub had floats on it. at one point we had 14 planes with floats on it at the site.

It is very possible but a river that is moving would be a problem. If you were on the lakeshore that had clearance along the shoreline that would be best. 1/2 over water, the 1/2 over land. Landing gets tricky because you need to land on the water unless you want to refinish your floats.

How about this? http://www.outerzone.co.uk/plan_details.asp?ID=3751

I suppose some sort of three-line system for throttle control must still exist for Carrier flying.

How heavy were your floats for stunt?

[M Spencer]

Of Course ya can . Here 1999 , original floats . ( couple of Tornado 10-6s on it there , rh & lh )


71 Torpedo 40 , unmuffled , a 11 x 5 , 63 ft. of .016 solids . Cept Ive Tarted it up , & as a OS  H40S is the same Wt  muffled it s in just now .

4055 abc K&B in it below , Sould keep that - For Musswellbrook . Its held ' in the sticks ' & those Dyna Jet Blokes turn up , too .

[M Spencer]

In Fact , in dream air , you wont find a more deadly accurate Aeroplane . ( Id just look at you as if you rode a CB 750 rather than laughing in your face , if you thought not ) .
Wind starts at 7 knots to introduce a lateral weave , due to the Fwd. Side Area . Floats There are more bouyant than the Original ( Sat at a scale loaded ' Sit '  Rear Strut Was Waterlevel , noses out )
Fine for Calm Water - But The Sharks Bite in a chop , and tryn pull them under - so a tip takes a time to rise . But as its a chop Someone Needs to Grab it fairly Smartly .

A Tip . If Its a Tidal River , your DOOMEd , even though saltwaters more bouyant . I landed it inverted with the FSRS in it at Whitianga years back . Open Cockpit . New Pushrods have got rid of the ruist . C R C the Lines .
Fresh Water would provide lower maintanace . Lacquer the Control System .

Same Wt. now as when built . Only had it in the Air twice ,. Since rebuild , I think. Not in ahurry  Concieved  70's . Built 1999 , Flown Nowra 2000 . Briefly . Repeatedly in N.Z.
 With the 71 Torp. Thats a 4055 in the pictures , here .
If its NOT as Good as it was . The Narrower Floats will be fitted . Flew of the Orewa Estuary With Them , Ride on a Canoe to the Mud Flats & a launch . Two Flights . Had to swim back ! .

Is Airworthy at the moment . But wannabe on the ball . Had a runnawayon the Torp at Dusk - Does about 90 mph . in the dark . and YOUR inverted ( as it were ) OPENING the Needle From 1 7/8 turns To One Turn, not TWO !
tthat good Enya needles GONE too , Sat Flush , Hollow End , Cut a Notch & used a srew driver . Needed Opening . Suppose I mustve Turned it IN 1 7/8 then opened it 2 Halves ( 2/2 ) when someone gabled . NO Distractions .
Please .

Nils and I still email on occasion. As I recall, he said that Magnum was an OPP and was already too heavy to be a good PA plane, so when he found out about the ROW event, he put the floats on it. What didn't help was the total weight was really high, like 6 lbs or something like that, plus the Vertical CG was terribly low, so it insisted on flying with the outboard tip high. As I recall, he had throttle control and an early type Fox Eagle .60 in it, and flew it at reduced throttle. He won the event by being a good flier, and managed both a good takeoff and landing on the water, with some level laps between.

I was at that Roseburg NW Regionals, but mostly just remember seeing PW flying (and winning) Expert PA with his second B-17 Stunter, and that it was a rainy weekend. I also met Wayne Trivin  and Rad Racer that weekend.  Steve

Are you going to fly if off water?

[Jim Svitko]

A local RC club here has float plane events.  If you have a club nearby you might ask if any of them do any such events and you might get some pointers and advice from them.

[Greg McCoy]

Put wings on this.

[Dane Martin]

Maybe these bad boys! An extra 5.5oz  http://www.ebay.com/itm/161713085471

These are light, but the plane they are designed for is 47 inch wingspan.  I am positive a ringmaster size plane can carry them, they might just look big.
 This is definitely one to ponder.
All my float flying is from rc. Including rc helicopters! Those are fun in the water

[M Spencer]

A Control Line Plane is FAIRLY LIGHT . The Displacement of the Floats required Isnt a Lot . say 200 / 250 %  Toatal Volume ( Submerged . ) 300 max , to keep the Drag / weight down . With say 1 or 1 1/2 prop clearance sitting
Horizontal . For Aerobating Ive kept the floats ' in ' to the plane , so the offset isnt excessive . Ive Set the floats ' neutral ' = Nose to half ar . . Hight at rear . Sight along em , fore & Aft to guestimate the ' Zero Lift ' , and set
to Zero Incidance with the wing . If say 2 - 3 deg. Nose Up & Down they look equal ' windage ' for lift . , is my theory . Maybe Toe in rather than Toe Out . You Need STIFF 5/32 Wire . 1/8 on the Macchi 72 isnt really good enough .

This ISNT my Drawing : but ive got this Bernard HV 220 Drawn Up , maybe ST 46 Size , scale based elongated . The WING is a Dead Ringer for the BERINGER Wing , Taper Wise . ( Maybe they copied it  )





for thopse of French Ancestry .  Give me a yell if you cant live without building one . TheDURAL Landing Gear Legs'd be easy . F Glass Floats and youd save time long term . Building THREE Fuselages is a bit tedious ! .



Cylinder Head would hide , side on , between the inverted cylinder banks . Was ( pleasantly ) surprised there were no ' assymetric '  issues with the S6B or Macchi 72 , bar you can feel the ' lower wings '
above or below going way slow , lifting . At the old 5 seconds odd a lap , the Macchi particularly is ; in the groove ' . Dunno Why but Im Not Complaining . But the floats lines are V Clean . No Great Drag , there .

[M Spencer]

Done preliminary Drgs for a ' 65 ' for two .25s . C F Yacht Battens , 3/8 x 1/2 would be simple ridgid booms. a bit weighty - 1/8 wall . But V Stiff , Would Need Jig Assembly I would think .



One of the Best Looking is the 67 , Straight Wing Again . But upright Engine . WOULD the thing work / one way to find out . 



Only Needing an Extension Shaft Ballrace set ups stopped me Starting Building THIS , its DRAWN . But its a HYDROFOIL , 45 deg. camber on hidden wheels would be ' intresting . Could tend to go on its roof ,
so might need a dodge , there .



longish nose , would the moment give torque twist trouble . Could always chop the longness away if it did .

Dubbed ' The Flying Submarine ' .

[M Spencer]

Ive Absconded with THESE from Europe. Its NOT me .





There FOAMY Electro MC 72s for R.C. Probly the quickest way to get going , If You DO have WATER . Chuck a Bellcrank in rather than that expensive short circuitry .

One Would Think REPLACEMENT FLOATS for the Fun Fly MC72 would be available , light , and ( maybe   cheap ??



  A Thousand Bucks should start to cover it .  

HERES A CHEAP STYRO MC67 Think theres a MC 72 too .

S6B Styro ,

hrumph / L Wt PB26 Twin Flying Boat . Keeping it Simple & to esesential Ellements. 

[Avaiojet]

Are you going to fly if off water?

Liner,

To fly the model off water I would have to have retracts, or at least for the front wheels. Retracts add weight. There will be enough weight already with the floats and wheels.

I'm designing the wing with a symmetrical airfoil so I can get some mild stunts out of the model. I have to keep the weight down as best as possible, so, I probably won't be flying it off of water.

For those interested, here's my progress.

Charles

[M Spencer]

Itll be intresting to see how it goes .

Think its easiest to carve say a pine float , 3/32 undersize , and mould the skins . Or just use plastic , particularly if you have a vacuforer .
If theres a 5 mm lip on the upper edge of the bottoms , glued inside the uppers sides , theyed be quite ridgid and weigh naff all .
a couple of formers to pick up Alumn. legs ?? ( that connection needs to be secure )

Fibreglass over a plug maybe better . If your really cunning Alloy U brackets for the wheels , could be screwed on , thus removable .
A tube 7 C clip in a groove in the wire , at front .

On Grass the suckers usually slide . Less So clockwise, its trying to pull outward . I think Counter Clock ( Normal ) the in turn ( tourque )
would have it sliding no worries . Mine are normally flown ion grass . Grass or Water , if you drop it from 1 inch up , its sliding fwd already.

Look at the old 15 Deg Wheel bit , for ' bouyancy ' as the force angle / CG on water , if you do try it , you dont want it driving the noses under .

Floats built as an assembly , jigged when fitting the legs , if That bolted on the fuse as a assembly , would be self aligning .
To soft in the legs and youve good big ' surfboards ' under there twisting away trying to steer the plane .

Dimensions akin to Old Time Stunt should work . Be intresting with the ; big ; floats theres a fair bit of LIFT in them , so conventional ' sums '
arnt allowing for that ' lifting area ' as wings , in the Oz / Sq Ft bit . If you dont go filling it up with concrette , it should work good .

You COULD just fit one wheel Ea Side , up inside the floats . Under the leading edge .
If they were hard team race disc wheels , a moulded cover up in it , a few brass tubes & a Press In axle would have them fittable or removable ,

Theyd only need to stick out 1/4 in . Ive Flown over smooth concrette , Spruce Runners on the keels , So you dont REALLY need wheels .

 



Dunno What Payload that thing carries , but its got a bit of freeboard . Has to have reseve capacity for storms & suchlike .

Your Probly better building a DC3 on floats . 



( Just Kidding about the DC3 !  )

Pye korrie .



The Early snow commanders had short noses and great round engines , The nose is long as the Turbo Prop weighs nothing , so watch the weight forward there ,
A exhaust elbow with the muffler aft of the L E might be usefull . It doesnt look like a Fox or OS Max 35 , theyre 6 ounces .

[Mark Scarborough]

yep,. the Snow S-2,(commander) became the Rockwell Thrush and Ayre Thrush
Leland Snow sold the rights and in doing so signed a no compete for a period of time, either 7 or 10 years, not toally sure. Then he produced the Air Tractor.
Now he has expanded the original AT301, 300 gallon, radial powered, and now it has become th AT-802 which also becomes the Fire Boss on floats. I am not sure that the yellow AT-802 isnt just the prototype of the Fire Boss.
interesting note, he also produced a version he marketed to smaller countries for civil defense use armed with missiles and such

[Mark Scarborough]

Just because,,
here is a link to the company I used to work for, I designed the conversion and helped get the conversion approved and the PMA in place. which originally was for a Walter M601 Turboprop installation. The Walter was mounted on the Let 410 commuter aircraft and is Czechoslovakian in origin.
Later they went to PT-6 for various reasons.

anyway, it is prettier than the FActory PT-6 installation IMHO

Any scientific location as to where you mount the floats besides on the bottom of the plane? Any relationship to the CG of the airplane?

Thanks for the links Mark. My favorite aircraft for sure.

[Chris Fretz]

HA! What do you think of the AquaRing? Maybe the floats are a little too far forward like Matt suggested. I have no Idea but its looking pretty cool.

[Tim Wescott]

AFAIK -- and I've never tried it on anything but rubber-power -- the step should be a bit behind the CG.  For a 40-sized plane the dimension I remember is 1/4 or 1/2 inch.  Dunno why, although it probably has to do with stability when it's up on the step.

pretty much what Tim said,
the step relates to the CG, normally the top of the float is parallel to the line of flight ( because most floats are designed so they can be rigged that way

The pontoon step is pretty close to the spare in the wing,  sounds like a winner to me.  You sure have a wide range of  knowledge Tim!

Sight Behind and left , for three strides aft ! . If Static Release . Dropping From a inch or two up ( aimed striaght )
seems to be instantly on the step & running true , so doesnt involve footwork .

The Kiwi Widgeons came over with a un ' bulliten ' Step posn . Was Moved Aft 9 in. or suchlike . On Occasion theyed
try the pirruette waltze on landing . Years Later someone realised the problem & the hulls were updated .

The STEP Posn. is a bit like the ' Rotation ' point . To Far Aft & the nose is glued down , but to short all the keels Fwd of the C.G.

Looking at it ' on the step ' , thwe rear of the keels in , only . That is about at the C.G.

Watch It with a Static Release , The Nose May Try'n Turn In under the acceleration . So Like a erant 2 Wheel Job - you may need to go aft
for line tension .Await the Flight Report . Looking GOOD .

[Chris Fretz]

I bet a water crash is epic looking!

So your saying the floats may be a little far forward, and on takeoff it might turn in at me?

[Dane Martin]

Kinda like a speed plane wants to turn in on you, you have to back up quick and keep tension on the lines.  With the prop spinning the direction it does and the fact that the pontoons will be stuck to the water, the plane will want to turn it's nose to you. I don't know the actual terms to use,  I just know how it feels. I also know how silly I feel when I get two spin outs in a row in a speed contest. ....

Makes sense! Is there any way to stop that if it happens?  Might be a good youtube video you guys see on Sunday

[Dane Martin]

Keep in mind,  I've flown plenty of float rc planes and helis, but no cl.... so if someone intelligent chimes in (like Tim or mark) that would be the way to go

I would fix a small slightly adjustable rudder on the right pontoon and add some pontoon offset rudder. Then,  get it going,  and off the water as soon as it is safe to do so.
So lots of horse power!  Lol
