The official 36" zelos twin modding thread

[JPriami]

Rafael, The Motors were Leopard 3674 2650Kv. ESCs swordfish pro 220. im a bit worried the abc props I have might be too much for the stock zelos electrics. But ill check temps and short test today.

Keagan-Z06, Its the 6th gen corvette. I used to have a C5 that I supercharged and did a lot of stuff too before I got hitched & was single. So after having a family and kids, i decided to get back into RC. So of course I built a boat & the paint scheme was after the 6th gen corvette race cars. I had a forum member make up the custom graphics for me. Also the C5 has a ring around the flags. C6 does not.

I think a Jake themed livery would do good from the C7R!

Keagan-Z06, the props I mention were from a custom build I did a few years ago. The Corvette twin 32" rivercat. I went about 80 mph with the abc props I mentioned on just 14.8v. The boat was never fully topped out as it still had the ability to run on 22.2v. So it's real top speed never was achived. I had a servo glitch and it wiped out. Part of the hull split so I retired the hull to shelf queen. Paint still looked good for that.

This rivercat is so bada$$ lol I went through your build thread last fall, beautiful boat I never knew you cracked it up you should definitely resurrect it lol

I got up early to beat the wind/rain and was rewarded. Testing Octura X447s on excellent water. First fast run was 73.4mph and the backup run was 73.7mph. I made a couple passes on 4S and it came out to 51.1mph. The best thing is that when my boat gets past about 60ish it settles down and runs dead flat. Amazingly smooth. So far, on lower speeds (like the 4S runs) it just bounces along and will not settle down. Anyway, excellent experience with these props. The acceleration is much better than my stock unsharpened props. I bet a lot of that was because they weren't sharpened though. All the temps were low. Motors got to around 100. ESC, cap pack, connectors, batteries all were around 90. Take note though that these were just speed runs for roughly half of my packs capacity. Sport running for an entire packs worth would give you higher temps and I haven't tested that. On top of that I was bringing it in regularly to check temps and speeds.

Wow congrats arrover! That thing is flying. This was just a prop change correct? Sharpened and balanced?

[arrover]

Thanks! Yes, prop change only. You HAVE to sharpen and balance Octura and ABC props before you run them.

73.4 and 73.7 mph with two (2) 3s batteries? Wow! Have you tried four (4) 3s packs?
What Mah and C rating are those packs? Brand?
I'm impressed! All that from a prop swap.
Good job!

Great job man !
what a cheap upgrade on a RTR and get over 70mph !

[arrover]

Thanks guys. I have not tried running dedicated 6S to each motor/esc yet. I've only run the Y harness with two 3S packs so far. The batteries are Hobbyking Turnigy Heavy Dutys, 5000mah. I think their C rating is something like 60-120 and they have 5.5mm bullets. I have two sets of these batteries and they have run well in my modded Voracity and now in the Zelos.

[Rafael_Lopez]

Very impressive Arrower. I have a set of those psops that I sharpened and balanced but have yet to try them. I've actually not been back on the water for some weeks now.

Thanks for the update and glad to her you're getting your boat settled in.

Do you have a hard time getting those Turnigy's? I am trying to get the graphene but back ordered!

[arrover]

I imagine you need a break from boats sometimes. To much of a good thing I would guess. It's hard for us hobbyist to imagine that!

Keagan, I think I had to wait for the batteries to be restocked last time I ordered. And just to be clear, the Turnigy packs have 5.5mm bullets so you will have to either change the EC5 connectors on the boat or solder EC5s on the batteries. They're not plug and play like Horizon's packs are.

Thanks man, I'll keep an eye out. My Dynamite packs are scheduled to come in tonight on cargo plane, so should be able to clear them at customs tomorrow! Also my Zelos was picked up a few minutes ago, like it never was hit!

This morning I wanted to test the x447 props with 15 degree timing but things just didn't go smoothly. I did verify that the 73+mph runs from the other day were with 7 degrees timing. I changed the timing to 15 degrees and upped the LVC to 3.4v for this morning. The boat continued to hit the LVC even with full packs so I disabled it. Then I flipped the boat 3 times on calm water before I realized that one strut had come out of adjustment. I eye balled it compared to the one that was still in adjustment and continued on. I could not seem to get the boat to run faster than 68._mph. I even turned the timing down to 11? degrees but nothing was working for me. In the end there were to many variables, things out of adjustment, and a little frustration so I packed it in. Still, it appears that the combination of this prop and increased timing wasn't the best. I'm going to try it again though.

Rafael, were you able to find out the wind of these motors? It would be helpful to know for timing purposes.
