Motor/Esc Recommendation for Spartan

[mojogator]

Really want to thank everybody for their feedback, suggestions, and candor. I appreciate everybody sharing their knowledge with me and not roasting me for being a noob.

Working with Steven here at OSE, I am going to go with the Leopard 4092 1730 and the 180 Seawing ESC. Looks like I am going to try this out with about a x442 prop.

Sound like a pretty good setup?

If Steven suggested it I would take his advise. 1730 will really rip! 38000 rpm should be good for some really fast sport running

Steven suggested the 4082 but agreed that we can do the 4092. It should go or blow. If it blows, good thing I am PADI certified

Well, Steven, from what I can tell, always gives an honest answer, and doesn't like to suggest a setup he isn't sure of, considering the fact that he knows, if it fails, he has to answer to the customer. I think you'll be safe -)

My dealings with Steven have been nothing short of fantastic. He appears to be very knowledgable and approachable. If you are reading this Steven, kudos to you!

Matt any feedback on this setup? i am ordering the same setup.

[mojogator]

It appears to be a good setup. Due to schedule I have not had a chance to run it much, but when I took it out, it was plenty fast (have not GPS'ed it yet). Two recommendations: Definitely order the programming card. I did not originally and for some reason, the programming would not stick when I tried to program manually. With the card, no problems. I lost a few weeks on this. The second recommendation: Shorten the wires coming from the ESC to go to the batteries. Steve did a very nice job putting everything together but the wires are super long. I shortened them to make the connection to the batteries easier to make. This should also help with the power flow from the batteries to the ESC (Impedance?) I should have more time to try everything else this weekend.

that is odd that the programming would not stick, i did not order the card with the ESC as there was not much to program with the 180 as compaired to one on my helis. well i will find out soon enough. keep me posted.
thanks

It was weird. The programming would not stick and for some reason, the throttle range setting did not take, either. I about chopped off my finger the first time the prop started turning full blast unexpectedly. I talked with Steve, watched youtube videos, everything without any luck. I must have been doing something wrong. Got the programming card and no issues. Good luck to you on this.

I have had trouble with one ECS that would not recognize the middle throttle position so when I went to low and then high it armed the ECS and started to swing a pair of 550 MM blades. Luckily I was fast and did not strip a gear or lose my head. LOL
Did you waterproof the ESC and do the cooling mod?

[mojogator]

Always have to watch out for the spinning sharp things :)

I did not waterproof the ESC with anything like CorrosionX but did seal up the receiver box with marine silicone. I mounted the ESC by cutting a few pieces of plastic to size, stacked them together and glued them with Gorilla Glue to make a base to get above the height of the radio tray. I used double sided tape to mount the esc to this base I made. I have wiped out a few times and everything held.

I am using a full cooling compliment on this (dual pickup rudder, dedicated cooling lines to motor and esc, etc) and the temperatures have been cool. I have the TQI radio and telemetry running with a motor temp gauge. I can not remember motor temps off the top of my head but will take a look this weekend.

[traeside]

Yeah I am worried if I do all the waterproofing if they will still repair it. I posed the question but got no replies. I can’t wait to hear how the weekend goes. Are you really running 2 8400? I was going to run my Heli batteries in there but I thought they would be too big so I got some 3S 5000’s

[mojogator]

Yep, I am running 2 8400 Traxxas packs. I have two sets. Have not had a problem with them.

[mojogator]

Here is a very brief clip of the boat running with the new motor config, 4 changemaker trim tabs, and 2 8400 packs. I did not have it fully dialed in on the trim. I blew a solder, so it cut the day short. As you can see, she is hauling and is pretty stable.

Sweet!
