Aquacraft Mini Rio (prop change - cavitation question)

[wparsons]

Tamiya plugs aren't great at all, but at the amperage needs of the stock motor they'll be fine. You'll have a hard time finding a lipo pack with a tamiya plug on it though.

This is the same pack my relative's mini rio runs on, and you'll also need a lipo charger.

I've used both these chargers and both work great. The Turnigy one requires a 12v power supply, the other one plugs right into the wall.

Am I missing something here? Why does that battery pack have 2 connectors?

And thanks SO much for your continuing help with my idiotic questions. It's very much appreciated!

One connector is for power, the other is for balancing while charging (or discharging with a charger).

Gotcha. So, put Deans connectors the proper set of wires on that battery pack, then cut of the Tamiya connector on the stock ESN and put a Deans connector on it and connect it up? I imagine the LVC switch would be connected between the stock ESC and the battery pack? Any recommendation on a LVC to use with the battery pack you recommended? As for the chargers you recommended, would the one that requires 12volt work fine with one of these?

Just to reiterate (I'm anal retentive, can't you tell? LOL), to do the LIPO swap I can keep everything stock and do the following:

1. Purchase Deans connectors (Would these be finef? http://www3.towerhobbies.com/cgi-bin...I=L5KX3903&P=K and hook one up to the ESC and one up to this LIPO battery (http://www.hobbyking.com/hobbyking/s...Lipo_Pack.html)

2. Setup some LVC between the stock ESC/RX and the battery.

3. Use one of the chargers you mentioned to charge it.

4. Have fun?

Thanks again!

That power supply won't have nearly enough juice, you'll want a 12v 10a supply for it to be much use.

This will work as a LVC, but to be honest I think the cutoff voltage is way too low. I like mine to be above 3.7v resting, which usually won't happen if they are at 3.2v under load.

Crap. That's the power supply I'm using to charge my MR. It seems to do the trick, but I imagine using a proper 12v 10a power supply is what I'll need to purchase. Hmmm, so I should find a LVC that has the cutoff at 3.7v or higher?

It all depends on the charger's needs to power it. You can get away with a ~5a power supply, but it might get hot.

Octura x431 TOTALLY solved the cavitation problem!

[wparsons]

IMO, run it as is then!

As long as you're having fun, just keep it as is.

If you decide you want something faster, I'd suggest this: http://www.aquacraftmodels.com/boats...ono/index.html It handles the power better, and won't require fiddling to get right like an upgraded mini rio will.

Thanks again for all your help! I'm going to keep it as is with the Octura because it gets on plane instantly and runs great. You made this guy and his 3yo son very happy! Only problem I had was that it's pretty easy to flip it over. Thank god for paddle boats!

That Mini Mono looks sweet!

Thanks again for everyones help!

If you're finding it easy to flip, definitely don't add more power then! It'll just make it much easier to flip :D

BTW, I contacted the group over at www.fastrcboats.com regarding the MR hop-up kit. They want $83 + s/h for the complete kit excluding the battery and battery charger. What a rip-off! You can get a whole new boat with a BL setup for $140 from Aquacraft!

[wparsons]

^^ I don't think their kit includes a new TX/RX either, I think it's just the motor, mount, ESC and prop.

You're right. Better off buying the Mini Mono for that amount of cash.

Well, today I was going to grease up my flex cable...looks like I'll be buying a new flex cable and coupler. Doh! I put a little loc-tite on one of the grub screws and I can't get it out now. Those dang things are soo easy to round out. I heard someone talking about cap screws I ordered these:

I'm hoping they'll work. At least I can remove the coupler from the motor. I'll just have to cut the cable and pull it all out after I get my new parts. If those cap screws I listed won't work, any recommendations? I've read about someone else who has used the with great results.
