HELP with setup for Atomik arc 58 cat

[TheShaughnessy]

They look nice. Have you made any progress towards reliability?

[Brewbud]

With that view I might just float my boat out, sit back with a brew, relax and never touch the throttle!

[Mr.Joshua]

Props should be arriving any day. I just weighed my boat with batteries and everything 19.2lbs I was wondering if it would be in my best interest to look at getting a lower kv motor like leopard 56110 700-800kv range any thoughts?image.jpg

I'd try it with the 1100kv you have now first, just remember short trips and check temps. when checking temps on the esc, check the main body and the ends of the caps. the caps will read a little higher than the main body by about 20deg.

But the props won't fit on the shaft.The shaft is like a 1/64 too big diameter image.jpg
So I'm using some fine grit sand paper rolled up to hone the inside of the prop until it fits? Unless there is a better way?

Dude, you are having some struggles! First off, and I don't know if it's been mentioned, but I would NOT run an 1100kv in this hull. I run a 910kv, and I think it's too much. 700-800kv will be my next motor option so I could spin a x455 3 blade.
My set up now is the Leo 5698 910kv, Castle 200HV with Dinogy 65c lipos, 2x4s for 8s. Prop is x452. Temps low and 5-8min run times depending on conditions. I run 8mm OSE bullets on all connections as well.

What size is the prop shaft on the boat? The sand paper roll seems like a lot of work, I'd just drill it to size.

[Mr.Joshua]

Shaft on boat is 13/64 exactly.Which is just a C-hair over 3/16. I don't have a drill press either .I bought the balanced & sharpened x450 &x452 props. I'm just worried about drilling such a small amount.What if drilled not perfectly in the center gonna mess up its balance?

[Mr.Joshua]

Yeah tell me about it what size is your hull ?

[WhatRLaws4]

If you are asking me, Ive got the same hull. Its the Venom King of Shaves 58" that I converted to brushless. I switched everything over to 1/4" using warehouse hobbies driveline, but I had them custom cut a 3/16" driveshaft to work on smaller props. I have a build thread on 2 of the forums, the easiest one to find is in the Venom section. Lots of detailed pics.

[Mr.Joshua]

Right on :) It's awesome to finally talk to someone who has the same boat.
So how long have you been running that setup?

[tlandauer]

I won't do anything to enlarge the hole on the prop unless you have the equipment.
Can you get the right shaft , i know it is easier said than done but you are right that if it is not done correctly it will have issues.
Wouldn't it be more practical to thin the shaft?

Well, same hull, different stringer layout. If I had the Atomik version, I would gut it and start over. Glass in some nice plywood or composite stringers, get the FDM or any other motor mount that fits 5" rails and you're good to go. Or just glass in a proper motor mount. I've been running mine for 2 years with no issue.

Here's the main build thread I had for reference. http://forums.offshoreelectrics.com/...ght=whatrlaws4

Well it was sad day today for my Seattle seahawks
But a good day for my boat it ran perfectly 😃 Temp after 30sec was 70deg ,put back in water. Checked temp after 1min was 85deg. Ran for 2 min temp was 100deg . Ran for another 2-1/2-3min temp was 120deg. Tried to use program box but couldn't get it to work.Brought it the house hooked up to laptop but couldn't get data Kept sayin it timed out
Or wrong com port .Frustrating👎
How do I hook up the swordfish to pull data?

[flraptor07]

Well Joshua I'm glad you got the running problem solved. The Swordfish data with the hand held program box you unplug the ESC from RX plug it into the box then plug your battery in and turn the switch on. Here's the program box manual, https://astecmodels.co.uk/pdfs/hifei...%20manuals.pdf
