The official 36" zelos twin modding thread

[Erroneous]

Let the modding begin. Went with swordfish 240s (overkill), poseidon 1515 2200kv motors and 4 revolectrix silver435 3s packs for 6s2p. Put the ESCs at the back of the batt tray, batts under the bow deck. Test ran yesterday in windy rough conditions. 2mm negative on struts for starters, smooth as can be considering conditions ( new hull Rapael ). Didnt GPS as was a test run but guessing 65ish. Running b/s/p x442s for now and will work into the Dasboata ABCs. Fun times ahead.

Has anyone ran the x645 props on this twin ?
reason I ask is on my Limited Sport Hydro I tried a 447 prop and ran low 50's then went with a 645 that I now race with, picked up 4mph and dropped temps by 15-20*

I'm on my phone but I don't believe that Octura makes a counter rotating x645.

Thank you, I think this is what I need for my QMono !

A 645 is definitely a faster prop (in most cases I've seen except a mono I had) but they don't make a reverse rotation version that I know of. Now. Abc makes some 1815's (I know your probably familiar with) that pull around the same amps (actually I've seen a touch less with the abcs) and they are about 10mph faster on my Rivercat.

I did try 1715's vs my 1814's and the 1715's lifted the nose too much.

Great info, thanks Travis..

What temps were you getting?

I went through a full 7600mah battery pack and esc Temps were 105 motors were 113 the only thing hot were the connectors were around 140

Anyone know if the stuffing tubes come installed in the bare hull of this thing? Thinking about picking up a hull to build this coming winter. I really like the looks of this boat lol

Yes they do.

Did you check the battery temps too?
How many batteries were you running?

Just got back from a good day at the lake. Tried 4 runs on my new OSE 43mm CNC Props and major difference over the stockers. No Cavitation and up to speed right away. Didn't have a GPS to check the speeds. Thinking the 45mm's will be on my next order.

What do you guys think of routing the ESC cooling hoses like this? It might eliminate a tiny bit of restriction in the cooling system and it cleans up the look of the boat. The downside would be if the front or rear of the ESCs is warmer than the other, one motor might run hotter. Can you think of any other downsides? I might have to try it.

That's how I run mine and get a little more flow

[kfxguy]

I guess just try it and keep track of temps.

Thanks Rafael, by tabs near the keel, what do you mean?

I know this is out of place and has nothing to do with the Zelos 36, but thought posting this here may help someone else.

Keagan, this is not my picture and I'm only using as reference to your question regarding mounting another set of tabs closer to the keel on the Voracity 36.


Ok, back on topic!

[Keagan-Z06]

Thanks Rafael. Will give it a shot when the caps come in.

Not my finest hour this morning.... I ran the twin into the dock doing at least 60mph. Nothing to blame except myself. Just a stupid, sad, $260 mistake. I did want to post the pictures because even though it really sucks, the hull is pretty darn impressive. The dock is a solid structure and the boat actually hit a piece of steel bracing. The batteries slid forward and securely wedged themselves under the deck (and ruined them at the same time). Both motors slid forward in the adjustable mounts but the mounts stayed attached to the hull. The main battery and electronics tray did not come unglued from the hull. Just a reminder of how serious these toys are and to be really careful around objects and especially people (don't run with people in the water).

If there was an upside to this morning, it was that I had just finished testing a new set of Y adapters built from 5.5 bullets. I switched the EC5 connectors on the ESCs to 5.5 bullets and ran four 3S packs the other day. X447 props got me to 73.2mph. This morning I ran two 3S packs with the new Y adapters that I built. You can see the positive adapter in the first picture. It replaces the stock EC5 Y harness that the boat comes with. Anyway, very close water conditions, same props, same batteries, no adjustments and it ran 72.5mph. So less than 1mph difference between the two battery setups. I wish I could have tested back to back on the same day but I don't have enough batteries to do that. If you're interested, here are a couple threads that talk about building these adapters: http://forums.offshoreelectrics.com/...llel-conectors and http://forums.offshoreelectrics.com/...light=parallel .
