Which electric motor for mono build?

[punit]

Hi Guys,

I'm new to electric motors but have been running gas for the past 20 years. I want to build a FAST single engine 57" mono that will be used for 6 lap heat racing,but would like suggestions or opinions on equipment. I have been looking at the Lehner,NEU and just yesterday saw a TP Power motor.... What's your thoughts on those motors also? I don't mind paying for the best quality equipment if it's worth the money.

Look forward to hearing from you all!

There are a lot of different answers depending on how you want to rig it and which organization you race in. 57" will require 10S2P and at minimum 10Ah or better yet 12Ah to be competitive with a gas mono.

The LMT 3080's and 3060's are both powerhouses, but you need a 300-450A controller which is much harder to source than the motor.
The Neu 2230 1Y is another good option and a little easier on controllers.
A Castle 2028 is also a possibility although it will require a lighter build to reduce the load on the motor.

You are looking at between $1k and $2.5k for the motor, controller and batteries.

I plan on racing in the NAMBA District 3 in Florida in the Super Boat Class which I may be racing against twins up to 53cc. Hull sizes vary between 55"-60". Is there anywhere I can look to purchase a 300-450A controller? I would prefer the powerhouse so the LMT it may end up being if I decide to go that route.

In my few dealings with lehner motors I've found they favor higher rpm conditions. May not be the case with the bigger lmt's, Tyler would know before I would. I would probably steer towards the neu for what your trying to do.

If you want bulletproof I would opt for the 800A version: http://www.mgm-controllers.com/race-...eries-pro.html

I have one with a 3080 in an electric motor dyno. This is the most reliable you are going to get for a big boat. If you were running 12S or 14S you could get away with the 400A version or if you were running a longer distance race where the current would be reduced. However for a 6 lap sprint you will be pushing the amperage.

Several of us have built 45" mono's with 3080's and have learned you need every bit of 300A to run at competitive speeds. Given the size of your hull, 400A would be the minimum.

If you want top shelf, it would be a 3080 with a MGM80063 and 10S2P with 12,000mAh total. That will put you in the front.

Op, I would listen to this guy^^^^

[punit]

Ok I will look into the products and let you know how I make out

I would trust Tyler's advice too.

However, we did just see a mono clean up in T sprint up here in MI on a 200amp Castle ICE. I've had no luck with the ICE myself but it was really getting it done at our race.

At least with an MGM you can get it repaired if something goes wrong.

WOW $1900 for a speed control may I ask why would anyone not rich just get a top of the line QuickDraw with pipe for less and not have to buy batteries and a motor

It's the challenge for many to be a little different.

I have many Quickdraw Pioneer 30.5 motors..... How fast do you think you can get one to push a 57" deep vee compared to a single electric motor? I have my single QD's pushing my current 57"-66" deep vee hulls in the 58 to mid 60mph range(race set-up for big offshore courses that we race). I'm hoping a single high powered electric motor can do better....if not I will forget about the electric set-up.

Is there such a way to convert electric power motors over to cc? Reason I'm asking is because I was told that electric motors can run in a NAMBA District 3 in Florida as long as I don't exceed the 52cc size limit. So was wondering if electric can be converted to cc in order to be legal and stay under their cc size limits.

Punit,

I single high power mono can do better than a Pioneer, but it will be a high end build as we have mentioned above. You won't beat a gas motor on bang for the buck.
There is no good way of comparing gas to electric power. You can make up any reasonable number you want to .
