5692x1340kv on 6s is it ok????

[crrcboatz]

If it is what esc would be good? Would be using 6s Hyperian 6250mah 35c 1pack in a 44" mono looking to go 55-60.

Yea that motor is will be great for 6s, I would go 6s2p though, meaning get another identical hyperion pack and run both packs together in parallel. Or grab 2 6s gens ace or turnigy packs. I am running 2 6s blue lipos in a 41" mono with a CC1717 and those batts do just fine, I think I may switch over to some 6s gens aces though. I love those batts! As far as esc's I am running a castle hydra 240 ice. I am sure someone will mention running a Swordfish 200 or a seaking 180 on 6s with that motor, but I don't ever run esc's to there max voltage, never seemed reliable to me. Anything over 5s I go to a HV esc.

Ice 240
Swordy 240hv

* those would work just fine.

Ok I have a castle ice 160hv that is new but will need a pistix for it. Will that work?? The specs on the motor say 110amps max so I thought the 160 should handle it ok. Plus the 160 has a cooling fan made by castle I installed on it.

The "specs" on the motor are pretty meaningless. You can prop that motor to pull far more than 110 amps. That said, the ICE160 should work if you don't get greedy with prop size. As long as you really do limit your amp draw to 110 amps, 6S1P/35C/6250 will be fine if the batteries are decent. I run my Q Sport Hydro on 6S1P/35C/6500/G3s pulling 150 amps just fine.

Your problem will be run time if you are sport running. Averaging 110 amps you'll have less than 3 minutes full throttle run time. And depending on weight and hull design, getting 55-60 mph in a 44" mono with under 2500 watts just won't happen. That usually requires at least 3500-4000 watts or more. With that setup pulling 110 amps you'll probably be in the mid/high 40s, again depending on the hull. If you pull 150 amps speeds should increase to near 50 but run time suffers.

Question for you Fluid. I would like to power an old Dumas Competition 40CF hull with brushless, would it be better to go 8s instead of 6s on a hull that big.

Wow great info Fluid. Ok well I have 2 of teh 6250mah Hyperians that r identical 6s 35c so will just use 2. I also have a swordfish 200A hv and a 240 hv castle so will go to one of those instead. Prop with a 455x3 ok??????????????????????

[Fluid]

I would start with an x455/2. The three-blade adds a lot of load. Remember that the advice above depends on the hull design and its weight, what are you runing??

[Boaterguy]

455 sounds a little big, i'd start in the X450- X452 range.

Re props on this set up, The 5692 motor on a t180 0n 6s has been used a number of times on various builds on this forum using X455 & even x457 2 bladers. That 3 blader is to big.

Here is the hull. It is 44" long and 13" wide at the transom.

Don't know if this info will help you or not but it's my two cents for the day. I just finished building an Aeromarine Avenger pro 44" Cat hull with a Leopard 5692 (1340) and a hobbywing 180 ESC with some extra capacitors that I added. I was anxious to run the boat last night after work so I didn't take and measurement tools (GPS, temp gun) ect but here is what my conclusion was. I ran it with a Pranther 240 prop and two Turnigy 5000 6S batteries in parallel. The boat ran much quicker than I wanted, I would say in the 45 mph or so give or take a few. My run times were just under 3 mins and the motor and ESC were very warm to the touch after the runs. I built this boat for large lakes and rougher water so at that speed it's too fast for what I want. I am going to try a Pranther 235 and an Octura 648 next to lower my temps and my top end. I will have all my data gear for the next trip out and record more info. Take this for what you may and hopefully you will get a bit of help from it but I am quite happy with this rather inexpensive setup. All the best and good luck with your setup. Andy

[crrcboatz]

Wow GOOD info Brownie!! Please keep me informed on ur future with the setup.

[Browning]

No worries, glad I could help. I have used a few of those ECS's in some boating projects and as long as you add a few extra capacitors, they work fine. I use Castle ESC's in my higher powered or more expesive applications but as a cheaper option, Hobbywing's work fine. Just don't "over prop" your boat on 6S and you will be fine. I have to takes those words of wisdom and apply them myself now and experiment with smaller props for more run time along with lower temps and speeds.

Here is a pic of the setup. Please excuse the way all the lines and wires have been run, it was all temporary for testing purposes.

whatrya doin with the 240? mind if I take it off your hands?
