Waverider Navaho build (large Apache style build)

[FastVee]

Yeah, it was the old esc that let the smoke out second time, -a bit more this time thought Glad it was mounted on the servo mount that is stainless steel!

-it was plugged to the motor that has slight "rattling noise" , so if the next esc goes poof plugged to it, I need to change that also, glad these parts are cheap so not that big of a deal.



Not yet ready for another big boat lol , thinking of the proboat stiletto or similar next.

The outward rotating made this so much better to drive! -I do know that most real boats have like that also, and I guess, for a reason.

I originally rotated them inwards to get the max. speed out, but it does not look that slow props turning outward eighter.

Im thinking of making another plug,my lad needs a project for school also hmmm i wonder lol.
Not sure what size to go with maybe 25-30",i have a lot of foam i could carve one out of and turn it into a plug ,something low and fast im thinking.
Any requests ? lol

Lol, here is a thought: -One thing I have allways wanted but not found is something like http://www.marino.fi/index.php/swing/ -just standard and simple open boat. , that and many boats like that are common where I live and (boats are build for 20-30hp outboards some use huge 70-90hp engines! 70knots is not rare sight here with these! it could be just a hull(no deck needed) and 2-3 plywood(or graphite/glass) seats.

that would need to be a bit larger then 25" to get the electrics under the rear seat etc... -but I also think that most outboards are for 25-30" boats

just dreaming here.

but If you build it, I have few friends that would go

Got the new esc´s today, first minute it moved faster then ever, checked temps ,everything cold to touch.

Another 30 sec later... poof, another fire inside! -just had cleaned most of the smell out and again.....


Yep, it was the same motor again so that is the reason the first esc burned and now another... -need to get another motor, or just go for the big leopards next.

That damned outrunner sure did fly pretty far ...

that sucks, did you figure out what was wrong with it?
It has to be something momentary if it ran fine for a minute.
Maybe the fish will figure it out, if you didn't clear the lake.

[Jacked1]

Did you change the timing or any programing on the esc's? And can you tell where the esc started to burn? That is a bummer!

[FastVee]

actually I threw the motor to shore, still have that to disassemble.

When I got the boat back, there was only the cooling plate and few wires inside, the esc was totalled and no idea where the burn started.-the middle fet layer was most damaged but that was most likely the hottest place anyways. Pretty shure that the motor had short somewhere cause other esc was cold even after the fire inside. That motor wont spin as freely as the other one. -maybe an bearing issue?

I did program both esc´s to 6s cutoff,30 deg. timing and 16khz -the 30 deg timing was mising from last esc´s, (ss boat series) these ss aircraft versions had that30 deg to use. -and these esc´s were colder to touch then the boat versions after 1 minute run.(and better throttle response)

I think that 30 deg timing made the other(the ok one) motor colder so these outrunners are more efficient on 30 deg. timing then 15 deg. I used last time?

[Jacked1]

Yea if the motor is harder to turn and there is nothing touching there prolly is a short. If it is simillar to turning the other motor with all the motor wire legs together that would be it. And that would totally screw up the esc fets. Also you are correct about the timming, these motors like 30 degrees, I have a ton of them!

[Boaterguy]

yeah, outrunners like high timing because they have more poles (more of something I forget what) and the ESC's have to keep up.

[FastVee]

Hey I just started thinking ..(not usually a good sign) -the esc´s started to burn after I changed the prop rotation outward. -could that draw more Amps? -maybe the motor is not to blame but me ? tore the motor apart and nothing visible wrong there. Tried also holding all of the 3 connectors together and it made the motor more difficult to turn by hand. It has never rotated as smooth as the other motor but maybe they are not that constant at manufacturing these and it is still ok.

I think I should try it again with a new esc and smaller props but not sure... -thoughts?

[CornelP]

Outrunners prefer normal rotation because of the fan built in the end bell. Spin it the other way and your cooling is almost gone...

[FastVee]

I dont think that is the issue here, eighter motor have never been over 45 deg. c. Was thinking that the outward rotation "pulls" the transom down (and draws more Amps) and inward pushes it up.

Inward there is one large "prop wash cone"(no idea what else to call it,both props push the water to the center of the transom)) ,and outward there is one "cone" on bots sides.

Not the best or easiest to understand what I´m trying to say, I´ll blame the language barries here...

These outrunners are symetrical so either direction is the same. I have had that problem before tho with the Typhoon 600.

[martno1fan]

I still think a new motor is whats needed,we dont want any more fires do we .
