Rio EP my thoughts

[Diesel6401]

Just changed the connectors on my batteries to deans and also changed the esc connector over as well. Sadly one of the wires on one of my batteries slipped out of my hand while soldering and may have shorted out the battery since it's not working now. Lucky it was only a $20 battery.

What prop are you guys using on your RIO's?

I did some runs yesterday and tried the stock prop on 2s then on 3s, then tried a y535 on 3s, then a CF48 on 2s then on 3s..
I meant to try my a s220 but totally forgot about that prop..
best speed was the CF48 on 3s and that only got me 19mph..

I'm going to try a Team Orion Revolution 13x1 on 2s with the y535 and see how that works

You used a cf48 on this boat!?!?! Holy crap, the propwalk must have been ridiculous!

[Brushless55]

nah, it really wasn't that bad..

Anyway of saving this batt or am I just outta luck?!?

Diesel, that happened to me once before, but with a lipo. That scared the out of me. I got lucky and was able to snatch one of the wires free. The lipo did survive. Thats why all of my lipos are cheap E-bay batteries.

Reaper.

Open up the pack, it could be just a bad tab..

The bare + & - wires touched while soldering. That could cause a bad tab?!? If that is the case how to fix?!?

First measure for voltage at the end of the 2 plugs wires...If reading is zero then next go around the shrink wrap where the plastic end cap is on the pack and cut around it and pull the cap off see if the wire melted off where they put it on to the pack if so just solder it back on...if this don't help and you find nothing under the cap then take the rear one off and look if the end tab got disconnected from the pack... Also how long was it shorted out for?

[Rumdog]

diesel, do you have a lipo charger?

[Diesel6401]

diesel, do you have a lipo charger?

No I don't. I did just purchase a nice new nimh charger though. Sadly it didn't recognize the battery either. Im going to have to open the pack up tomorrow. Reason I bout a new charger is the brand new 7c 4600mah battery I got in the mail yesterday is having problems already. I charged booth batteries and one said done in like 20ms which i knew was a bunch of crap so I threw both new batteries in my sv27 which i also got yesterday and I got nothin. I then took the battery and threw it in my RIO and the ESC wouldn't even turn on so I bought a better charger and the battery seems to be taking a good charge now. And since I now have a digital read out I can tell the battery is really charging. I took the good 7c i had and through it in the RIO and boy did it wake that thing up. I didn't gps it but it was that fastest the boat has ever gone and the biggest rooster tail the boat has ever had. Just a quess I say pushing 18mph and the titan 12t really woke up with the 8.4v batt.

It was shorted for about a 1 second, super quick. I have to take it to work tomorrow because my Fluke meter is in my tool box and I don't have one at the house.

Hi what model charger are you using?

Hi what model charger are you using?

I was using the duratrax onyx 100 which didn't allow me to view the input or change the inputs. I am now using the duratrax pirahna digital peak charger and so for so good.
