So the xt60 connectors are better than deans?
My charger is deans too but I was thinking of making
a jumper from deans to xt60 to charge them.
Also where do you put the antenna from the rx, or
should I get the 2.4ghz system from hobbycity?

Yura

If you don't have a lot of baterries with Deans to use and plan to buy other from HK, you should look for XT60. Replace connector on ESC or make adapter cable.

I took out the stock spring antenna as I don't like it and taped the hole - will epoxy it later on.
I bored a hole on top, the size of an antenna tube.(Tight fitting hole, you don'twant it loose)
Pushed the antenna in, then usedclear epoxy to glue it inside the hull.

The 2.4Ghz is good. Yura seems to be ok with the GT2. I'm using Spektrum.
I chose the DX3S (DSM) simply because it has telemetry. But they came out with a marine version . . .
and it's compatible with DSM and DSM2 Rx's. They alsohave an entry level radio - DX3E.
You don't really need all the bells and whistles in a boat.

Here's the picture of the relocated antenna.

The flexshaft was spinning in the collet so I tried to tighten the small
screws and almost stripped them[:@] What size are the screws so I can
go the HS and get some good ones..thanks.
Also how do you get the flex shaft out. It won't slide out.

madmax93

ok I fiqured out how to get the shaft out, the hard way.

carakter

Can somebody please measure the motor shaft and flexcable diameter?
I don't have a caliper so I can only guess.
Looking to replace the coupler with a collet type.

carakter

I'm guessing it's M2.5 or M3 size. Look for stainless ones and be sure to apply threadlock.

Yura

M3x3

madmax93

i'm getting .090 for the shaft and .125 for the cable, both in inches.
Sorry but I do not have a mm caliper.

carakter

Okay so that's . . .

.090 = 2.3mm rounded off

.125 = 3.175mm

Thanks! Now off to find a collet coupler . . .

Carakter, are you still waiting for your maiden run?

carakter

Sadly . . . yes . . .
The nearest decent pond I can go to is an hour and a half away from me. . . .however, there is this small pond I can go to. . .
actually it's the City Hall pond . . . but they use the pond water forthe plants and the grass . . .so the level gets down quite a bit.
I will try again this Sunday and hopefully, the rains replenish and raise the water level.

I'm feeling so frustrated. I have this boat all ready to maiden . . and all I can do right now is look at it.

nickster46

that's frustrating, yes!
But I guess that just by looking to it, you start thinking about mods. just to be busy with the boat
But, when you start running it in the water you just concentrate on running it!than the mods will be repairs only. (allright, maybe you start testing some batteries and motors)
Are you going to run it on 3s or 4s? and with upgraded esc and motor or stock ones?

carakter

Right now it's all stock.
I have the 4200Kv outrunner in the bag and the Octura props coming in.
I will see how far I can go with the stock esc.
I will be using the 2200mah 3S nano-tech.
As stated, I want to replace the motor coupler , can't find a collet type though.
This type squeezes the cable, much like how you mount a drill bit in a electric drill.
What we have in the Bolt right now is a staight coupler which uses grub screws to hold everything.

I am also looking at getting a sponson turn fin to aid in the fast corner turns.
Like the image below from OSE . .


Hopefully I can maiden it this Sunday.
My boat buddies are all busy right now so that's not helping me to get motivated and make that 1.5hrs. drive to the big pond.

Oh how I wish I also had a pond beside me!

madmax93

Whats everybody doing to hold down the new servo if a new one was used.

carakter

I use 5 min. clear epoxy. Stays somewhat pliable if you have to take it out.
Don't use anything permanent. You will destroy that thin FG hull!

Yura

I have used glue gun for this purpose...

nickster46

same here for me.

Yura

Not so far away
The lake, where I can run it now is 160km away And it takes about 2-3hours driving to it.
(I need real boat to swim for Small bolt if flipped because it's quite cold water now and there it is)

nickster46

Whooowww!that's quite a distance. When I had to drive that distance I definately NOT bought a boat.
50m from my house is a small ditch. and 5mins away there is a big lake! And in the whole area are lots of ditches and little lakes in the park.
The letter A in the picture marks my house. you see the little ditch in the cirkle and the big lake on 5 min's traveling. on the left there is the area where I took the video

Yura

Why NOT?

carakter

@Yura - I concur with nickster . . . Wow!

And here I am complaining about the driving distance! Gotta hand it to you Yura . . you're one dedicated boater!

@nickster - ok stop already! You don't need to rub it in . . . I am just dying with envy here about you being so close to a lake!

madmax93

I powered up my boat and would like to know if it is normal for the motor to hesitate
at first and then spin faster. I hope that explains it somewhat.

carakter

More details please.

Was it in water or bench testing?
By hesitation, did you mean you gunned it and it took a while to wind up?
Or did it cog (stop-go-stop-go) until it eventually spinned faster?

Normally (bench testing), you press the trigger and it spools up fast.
