The official 36" zelos twin modding thread

[kfxguy]

This boat does not need 8s to go fast. At all. Choose the right component and a 6s setup will outrun an over kill 8s setup. Something you guys aren't considering either, weight. This super thin hull with 8s worth of batteries is going to be heavy. You think it'll survive a nice flip with all that weight? Surely when 8s is referred to, it's 8s per motor? Not just two 4s packs in series running two motors? I think that's too much current draw for that. So why not do this correctly? Build a 5s or 6s setup. 6s use 2000kv 4050 tp motors or a 5s run 2200-2300kv motors. It'll run 90+ easily if you can keep it on the water.


I don't recommend trying to go over 70 with this hull however, unless you pulled it all apart and reinforced it and gave it a nice inlay. You better jb weld the motor mounts in place too.

Question: in order to qualify for a place in the top speed zelos 36 thread, does the boat have to be in one piece at the end of the run?

For example, say you go airborne during the run, the hull explodes but you're able to retrieve the GPS which reports a record speed before the crash. Does that count?

You might get a quicker response if you posted on that thread..but the GPS will record the blowoff/crash speed and NOT the on water speed.

I figured, since we're still discussing setups (8s being worth it vs 6s) and it applies to acheiving top speed it was in the ballpark of relevance. It might make Travis a little irritated, but I'll still post more build stuff here, too, to keep this on topic.

For GPS I use a Garmin etrex Vista C that updates every second. It will show me the max speed acheived, and since the boat has all kinetic energy, it will not speed up once it leaves the surface of the water.

Any suggestions on connectors, I'm running stock for now but today after a long swim lol it appears the ec5's unsoldered, I would like to mod the zelos to be more efficient the speed is more than enough for me I'd just like to run the boat longer without temperature issues? Maybe different esc's ?

That GPS must be awesome! I'll have to check it out. My experiences have been when the boat lifted off the water the speeds were very seldom correct by showing more speed than they actually are going. I also noticed that Mike Zaborowski (Grim Racer) and a few others have had experiences like mine with their GPS units. Check out their post of another Boat review below.

no the boat wont speed up but the sudden impact can generate g forces that will show a higher speed than what the boat actually ran
I've had this happen twice to me when checking speeds with a GPS
one boat had a 15mph increase in top speed from the sudden impact.

I only get irritated when people post questions about problems with their new stock boat. Put new escs and Or motors in and have a problem, great, we might can help. But stock boat issues, nah. That's not what I created this thread for. I wanted to make this so people that modify their boats and get good speed out of it can share what they did....even if it's just a prop swap.

I thought the speed up was when the boat came out the water and into the air relieving itself of water drag momentarily? It's always seemed to me that that's what happens, I could be wrong tho.

You could be correct?

Yes - that is the way it works.
As the front of the boat lifts - the props can push it about 10 times easer, therefore (faster) speeding up the hull and raising the GPS reading about 10 to 15MPH. for a split second before complete blow over.

But if the boat is already out of the water like how most of mine run is not going to loosen up much more to gain 15mph on a push for a half a second

Run cnc props with caution. The blades dont like high rpm.

Thanks KFX, I'll order some up. One other question with boats the motors come with small gauge wire and no solder tabs this seems odd as when running cars you have the option of adding short large wires for lower resistance. As discussed here in the boat forums the boats draw lots of current so this seems odd. Any thoughts? Thanks again
