pics look good the motor looks ok give it a try,is that the 50 cc one should push it ok its not as big as i thought.mind you thats a canoe .

STEVE MARSHALL

In the pic of the motor, I see a bearing on the clutch housing, did it have a gearbox on it?? was it a overdrive or underdrive.
Steve

s2sinner

Hello Steve.

Well I know what you mean....
I hope the 470 let the motor run if not i will start play with other props and for sure with another motor.

s2sinner

Was a gearbox there and i take it out.....was 12:1 also that motor have electric starter on but i take it out as well..

s2sinner

This is the 51.7cc i will test it and we will see how it goes......If is not enough i will try another engine....It is a Canoe....hahahhahahahaha

We will see, after all i believe is the first one of this plans it goes in the water soon....



Today we make the exhaust pipe new and some parts to hold the motor on the hull.....if all is ok Sunday I will make that video i promise...... Bad or Good.

s2sinner

Some details


The motor comes from here [link=http://xingyue.us/product_gd.php?id3=323]Xingyue[/link]

I have another one from Honda and one from Okay ( Husqvarna ) and we will see wich one goes better......

The boat with the motor and drive system so far is 8.3 kilos
Electronics and some other parts needed it make it 8.9 kilos
plus the petrol

Also there is a big problem to find parts here in Swtzerland and i have to order them from Internet because i buy the X470 here for 75 USD

So is 3 or 4 times more than the real cost is.



Steve you have try the 470 on your boat yet??? if yes let me know how it goes ( if your motor goes up to the limit of RPM ) thanks

you might need a bigger porop for that honda motor maybe try a prather 280 or similar,or try one of the ali 78 mm props from here,ive run these and theyre good props but the 78 mm was atad big for my zen so ive reduced the diam,still havent tested that one yet [X(].theres two 78 mm ones mine was the smaller pitch one.the 470 is more for higher rpm motors,i have the x470 on my zen now.

I will try it first and then we will see.... To order bigger prop with out test is not a good idea...

Sunday test and then we will see...

s2sinner

I have one question....maybe you can help me with that....

I have one Futaba PL2 with s3003 servos....they are ok for use in the boat or I need something Special
( I mean i can use the s3003 for the garb and something bigger and stronger for the steering.)

s2sinner

Well I try today the boat and all was ok

I get on GPS 33 MPH the only problem is that the X470 is too small for my engine....

Message for Doug:
The boat is perfect.
With 51.7cc ( made in china.)
Octura X470 the XPD III Drive and 1 liter of petrol comes out of the water easy and is very very stable on running ( with 33 MPH )
even on fast turns.

So im the first one test that (72'') so far.

Sory for no video but I was alone and i cant make it all. I promise that week I will make some videos also for you.
Thanks for the great plans.

Looking good,i've always fancied a real big boat.Should be good in the open sea.
Still looks quite cold over there in Greece?
