My Rio EP Brushless conversion

Hyrule you might have to order "Mikes Pistix" for your esc. It allows an airplane esc to work with a pistol grip radio. If your charger wont charge two of your batteries it has to be because there is a bad connection at one of your connectors on the battery side. Or the batteries might be bad even though one is new. The charger you have works very well, I have never had a problem with mine.

thank you for the suggestions. I looked at Mikes Pistix but its out of stock right now and Im not sure how to install it. Would you just plug the three prong end on the pistix into the female plug of the esc and the other end of the pistix into the reciever? Thats how it looks like it would work anyway. Im waiting on tech support where I got it to reply and see what they say before I order anything.

As for my battery and charger I figured the battery was the problem, Im going to resolder the deans connectors and see if that helps. The new battery that I got has a very large wire for the discharge leads and are hard to solder to the deans connectors. Do you have any suggestions for soldering these big wires securely to the deans?

Thanks

PS im waiting on 2 more things in the mail before I can complete the project. The ESC cooling plate and the motor coupler.

Soon hopefully!

Hyrule where did you try and find the Pistix? Was it with OSE because they are in fact out of stock but there is another place that has them in stock. I know because I ordered mine from there. I'm not sure if its okay for me to post that place but here it is. OSE please dont band me from the forum I'm just trying to help a forum brother. Mikes subworks has them in stock and he shipped right away. You will have to place your order over the phone. Hope this helps you.

Thanks I will definatly use them if I determine that i need it.

Okay, so things have been busy around here with exams and such at school and not to metion all the parts have been arriving slowly. I'm still waiting for the motor coupler for the arrow wind. I modified the coupler that came with the Rio Ep to fit my new motor shaft and it works well.

My ESCs are working totally fine now, and are working as planned. I took it out today to get a test run for the first time but didn't have time to take a video because I flipped it while getting the feel of this boat and it was getting dark. Unfortunatly, I hadn't full sealed the box for the servo and receiver yet so water got in when it filpped and shorted the receiver out. No big deal though because I have an extra just in case.

I did find I have a problem, the motor has too much torque and it moves in it's cradle in the boat so I need a motor holder that will screw into the front of the motor itself.

My second problem was the boat started turning right at near full speed but I didn't have time to try and adjust the rudder and see if it helps. Next time I will do that but after the flip was recovered it was dark and there wasn't time to continue.

Thirdly, I need a new motor coupler, the one's I ordered haven't gotten here and it's been 2 weeks I'm in the process of talking to the people I ordered it from but I have since decided I want a different kind of coupler than the one I ordered. The one I ordered was just like the one that came with the Rio EP to start with but I am thinking I would rather have one that is the design of this one:

But I need a 4mm shaft hole and a 2mm flex shaft hole ( the one that screws in).

Can anyone suggest a coupler for the motor and for a motor mount?

Here also, is a picture but without the battery or receiver put in.

So,everything is here, installed and I am ready to run!!! Hopefully I will be able to take a run out to the Lake sometime this week, perhaps monday or wednesday, and video the Rio EP. I'm excited to try it because both the boats are finished. I will post videos and pictures later once I make a run with them.

I did solve my problem with the motor torque and spinning itself around in it's cradle. I cut a piece of the rubber lid openers we have up to fit around the motor and screwed the brace back in place. It fit perfectly and the motor definetly isn't going anywhere!

Till Next time!

Video please!!

[hyrulejedi86]

OKAY!!!! So, I've got a video here of the Rio EP running at the Lake.

Check it out and see what you think. I have noticed a couple things and am hoping for some suggestions on these issues:

1) I am noticing that it isn't getting on plane as quickly as I would like. I am using a 34mm prop. I was thinking about trying a smaller one but I don't know if that will get on plane sooner or go faster or what. It is a 31mm prop I'm thinking about. I also, thought about trying the stock prop just to see what happens.

2) If I move the battery from the back where it was designed to go to behind the motor do you think that will help even out the weight and help it get on plane faster?

3) I was having some serious problems with it rotaing to the right in the water at higher speeds but the metal fins solved that problem.

4) If you don't like the props I suggested above can someone supply me with a link of one or two that should work well?\

Hope the video looks good!

Definately moved the battery back. It'll jump on plane waaaay faster. Try that first, then diff. props. Do not run the stock prop. It'll be way too big.

[hyrulejedi86]

Ok, so I took it out again today and did a little experimenting with props.

First I tried a smaller prop I had, 31mm, and it was worse than the 34. So, I tried the only other prop I had, the stock prop. It worked AMAZINGLY, it picked up on plane, immediatly, got a great top speed and was overall very good.

Now, I just have to find a better prop of the same type because the stock is made of a cheap plastic.

Here is the video:

Sorry about the shakyness. I'm going to go again tomorrow as long as it doesn't rain and I'll take a video with my cheap HD camera and hopefully from a little father away.
Till then, feel free to make suggestions, and incase anyone is wondering, the motor and ESC didnt get overly warm using that prop.

[Brushless55]

Looks good...
I would try a 40mm and see how that goes..
how were your temps with the stock 42mm prop?

[SweetZ28]

I have a 31.5mm prop on my brushless apache and it's pretty fast on 3s but my battery runs a little hot I am going to try a little smaller prop ....with your 3600kv with those props you are using don't your battery get hot?

Mine would probly not get as hot but i ran all the way down to lipo cut off.
see my video

My temps were fine, battery wasn't hot at all but the motor and ESC got warm not so hot I couldn't touch them and hold my fingers there. I wouldn't mind going down a size but I tried the 31 and 34mm props from Hobbycity and they just won't push it on plane or get much speed. Can you guys give me a link to a couple of smaller props with higher pitches. maybe even a 3 blade prop that would work. I don't want to burn anything out but I want speed!!

I wouldn't mind a smaller prop but the one's I have just dont cut it right now.

[hyrulejedi86]

Oh, P.S. W/o the water cooling then they would get quite hot but since I have water cooling hooked up it keeps them much cooler.
