Somewhere in this thread are videos of a SS with pontoons.

You should be able to find it using the search function.

There is a picture on post # 7891 and a video on post # 7949 & # 8420

Thanks, The plane flying with floats looks like a Cessna 182. It lands takes off and flys, stock motor and prop 2200 mah bat and how to attach the floats. They say and show it's supper stable.

Eagle you pointed me to the 'mother load' on this.

About props and motors. Going up in pitch on a gas boat motor creates more speed but less power, going down = less speed but more power. Do these electric motors and props work that way?

A larger prop pitch number = more speed and more amps = less thrust.

I am not sure what you mean by less power.

I see why, how to put this...
With the boat example: I was a competition water skier thru the 60's. In a water ski show one might use a 17 pitch prop if one is pulling a bare foot skyier. Moves forward 17" each rev at the top of the power curve say 5,600 rpms. Speed 36 mph. The next act is 5 women with flags, to get them out of the water it takes 13" prop and at 5,600 is 22mph. The first one 17 pitch we call a speed prop. The 13" is a power prop.
I don't know if that is the same with our brushless motor and prop relationship.
I hope this helps.

If you go to search and in user type Shimmy. This is 2 wks old. The board walked him thru the whole process. That young man, 15 ask some very relevant question.

It is most of what you are wanting to know.

Check out page # 1 of this thread. Most of those mods are mentioned there.

I love being called a young man. At 54 it does not happen too often. ( My son sometimes does ask me if I will every act mature).

I still have not purchased all the additional equipment (the RTF is on its way to me).
Much of the stuff is back ordered and I have to figure out about shipping the LIPO's (also back ordered). There are mailing restrictions that require a big box if you are shipping more than 3400 maH

The Chinese eBay (TaoBao) sells the SkySurfer kit with Pontoons.

http://item.taobao.com/item.htm?spm=...id=15258958803

1 USD = 6.3 Renminbi so 200 Renminbi is about $31 for the kit.

So Bixler #2 is also going to carry a heap of FPV and am considering a motor change. I already have the CNC adjustable motor mount. Now need some advice on motor and prop combo.

I had an idea to put a PZ Stryker motor (2200Kv) on with the stock prop setup and 40A ESC, however I am not looking for speed, more so torque to carry added weight of FPV gear whilst retaining battery efficiency. Why switch from stock motor? Well I wanted to go for a more reliable (not that I have had any trouble with Bix 1) motor and prop that was more suited to FPV use.

Thanks in advance.
Since you have the CNC motor mount you can run up to an 8" prop which will be more efficient with more thrust (torque). I run a 450 sport (headsuprc) 1200kv motor with an APC 8x6SF prop that only draws 15A and much quieter operation. With a 8x5 or 8x3.8 even more thrust at lower current. Headsup does not ship to AUS but you should find something like it that does.

Can you link us to this motor?
I am building my second SkySurfer too.
Oh is this the one??

Yes, very much the same.
Lower pitch, more thrust (power, torque) less speed at same RPM (like a car in 1st gear).
Higher pitch, more speed, less thrust at same RPM (like a car in 4th gear).

But you would not pull up a skier with a 2hp motor no mater what prop used.

Yes, that should work great.
When I bought mine back some time ago it was listed as 1200kv.
The new EZII calls for a 1100kv motor with a 7x6 prop, so a 8" prop should give even more thrust. You do need the raised motor mount.
Jeff at Headsup has always been great!

Shimmy, truely thought you posted that you were 15 years old. I went back thru your post. Didn't find you saying that anywhere. Know wonder I get in trouble on this board.
