What To Use To Power A 45" Mono

[Mike Byer]

What motor/speed control/batteries should I look for to power a 45" mono? I've got a new bare lite hull I'd like to learn about battery power with.

Mike, I'd get in touch with Doug Smock, I'm sure he would be glad to talk you through "Eating Amps"

I usually jump on somthing new right away and spend a ton on stuff that won't work, but this time I thought I'd wait a while and see what shook out of this electric thing. Not looking to be a record setting project just something that will give decent run time and not make smoke right away, but make decent speed. By now I'd think someone would have a package like that in the US.

This is what we've tried.

I'd probably run motors from these days

Oops, I was thinking a .45 nitro size mono.

I have been watching this thread , hoping some one would give you some help. I seldom comment .

I run a NEU 2215 2Y on 10 S 8000 mah in a 45" Insane gas Mono in Open Oval with the gas boats .

Id suggest a big motor , NEU 2215 , Castle 2028 , large Lepoard or TP with a KV of 800 or lower on 10 S .

You can get byy with on an 8S setup , same motors with a KV about 1000 .

I started in this boat with a Sea King 130 and conservative props for a couple years . This season I'm running a CC Ice 200 .

Decent run time may be 3 min or less . Speed won't be a problem .

I checked your other posts and didn't see much about FE .

If this is your first FE , Get some HV experienced help , or start with a 4S P size boat to start . A small mistake can burn up a lot of $ .

I'm looking at motors with an 8mm shaft, 1800-2200 kv, and a can size of 56x110. Speed controllers of 225+ and haven't even thought much on the batteries yet

 

[Mike Byer]

Thanks, I think we were typing at the same time, I'll look at the lower kv motors, seems like there is a 5698 2y with kv of 910

 

[Flyguy55]

Rule of thumb multiply the KV by the pack voltage , 25,000 rpm to 28,000 is a good starting place . nitro size props .

What dia. drive cable are you using?

Here is a build thread I posted on a 45" DF Sniper. This is towards the high end of builds, but has a lot of good info.

 

[RaceMechaniX]

I cannot post the link, but search on OSE for "DF Sniper 45 T-mono build"

 

[Flyguy55]

1/4" . Your talking probably more HP and Torque then most Gas boats .

 

[Flyguy55]

Don't be concerned about weight . build it strong ! Often we have to add weight to keep them on the water .

 

[Mike Byer]

thanks, I appreciate your input.

You have a PM

if u are going to run a castle 2028 or neu 2215 etc you are into the high dollar stuff as u will probably be into at least 8 cell battery(4 4s or if u go 10s 4 5 s batteries) u are probab;y talking 1500 bucks at least....I have a 47 inch mono with a castle 2028 cc 200hv esc etc and I stop counting at a grand.....good luck with it

 

[Mike Byer]

batteries are what I've been looking at lately any good places to shop for them?
