Insane Mono for P Mono class-any tips?

[1BadIndian]

I picked up an Insane 34" Mono from the local hobby shop. It came with a 4082 1600kv motor a OSE 150esc and an Octura 642 prop which I know is WAY too small.

Anyone have a decent starting point setup for what motor and prop?

[Panchothedog]

That should be plenty of motor. Why don't you run it and check temperature. 6-S with a 44-45 mm prop depending on pitch should move that hull along quite nicely. If you don't already have a temperature gun, go out and buy one.

Our club doesn't run 6s P mono, only P limited mono on 4s

If you wAnt to race that, you could start with a 48mm 3 blade and go up. Your limiting factor will be the 150amp esc. Definitely keep temps under control. I run the castle mamba monster X8s and, like all in our club who do, am super happy with temps. With a bigger esc, I suspect you could end up with a 452/3 prop and high 50s for speed, depending on your setup.

I'm not opposed to changing the motor if needed as well.

First things first, the subject says P Mono. Then in a comment you mentioned your club only runs P-Limited Mono. Which is it? P Mono there are no motor restrictions, you can use anything. P-Limited mono you are limited to a maximum of a 3660 sized motor, hence, the limited part.

If you're going for full P, you're going to end up with a lot of prop considering the low kv rating of that motor. That little X642 is not enough, you're right. Even an X648 is leaving about 5mph on the table to be competitive in my club. But it could work. Switching over to the ABC props, a 1916 17-45 or even 1917 17-45 would probably get you competitive with that motor. All that said, while it can work, your prop selection options go way down with that low of a kv motor on 4S. Something in the 1900-2300kv range would be more typical, and open you up to many more prop options.

If you're going for P-Limited, you're going to have to buy a motor, as that one is too large to be legal for Limited.

She's too fat for limited mono. I know the boat. It's a heavy lay up.

If you want to try racing it with us you would swap out the motor for a 36mmx60mm motor at any kv. Shoot for around 2000kv. Best out of the box option in my opinion is the Dynamite. I like that it's 6 poles. Has a tic more torque as a result. Runs cooler than say a Leopard that's 2000kv.

Then maybe 6000mah worth of 4s batteries. Start around 45mm for a prop. ABC 1814-17-45 propeller. Check heat after a couple laps. Work up from there

I think Frank tried that boat on a limited setup before he decided to buy the Raider from OSE. I can't totally remember though. He tries all kinds of things.......cuz he's a junky. Have you seen the twin cat he bought from OSE? Holy crap.

Thanks everyone. Sorry tbonemcniel I was not accurate in the original subject line. I am just starting out in the electric boat world of racing. Met a couple of the guys from the local race pond and the bug has bitten me pretty hard. I'm not totally new to boats as I raced competitively until 2005 in the gas world, though I was IMPBA. Look forward to getting this boats under way and then also spreading anything I learn along the way to a guy just like me down the road. After all if we don't promote the sport and grow it, then it will only be a few of us old guys standing on the driver stand trying to make up enough boats to run a class.

Of course! That was me a couple years ago. Your fellow club member TS Davis nailed a P-Limited Mono setup. He almost described mine. Mine is a fiberglass TFL Pursuit hull, OSE Raider ESC, Leopard 3660 2050kv motor, 6,000 mAh of 4S, and a 45mm prop. She does great and has won me quite a few races.

If you’re serious about spec mono you’re gonna run a cut down leopard or tenshock czll2240 2020 kv Cut down and shortened by Don or a 1415 cut down. If you want something that pulls really pull hard you want a viper motor. And you need a castle ESC you need to know exactly what’s going on with the motor.

[1BadIndian]

Greg any more info about the motors you listed? Thanks man

This recently killed my interest in this class. If I had known this was going on before I sold Tom that cat I wouldn't have sold it. Oh well...

[Greg Schweers]

The motor rule change actually save me money when you’re running 5 to 6 classes a day you’re gonna burn stuff up. i’ve been running rewound motors now for over two years I haven’t burned one up yet. I remember years ago when everybody was running UL one motors I bought over 30 UL1. I can’t imagine how many pro boat 2000 motors I bought and burned up.

[T.S.Davis]

Me too Greg. I have de-soldered a couple connectors but no failures yet. No ESC failures in limited either. I ripped a sporty in half. It bobbed in the water for a bit. Hung from the flotation. Took all the parts out of it and dropped in a new boat. Raced it all season. I did injure a 2D motor pretty bad in a Raptor but that makes perfect sense. Even that didn't go thermal nuclear.

[ray schrauwen]

I just don't see much of a difference between Lmtd and full P classes anymore. There is no limit to the power people are putting into a 60mm long can. And the $200 Tenshock motor is 38mm in diameter, I thought the rule was max 37.1mm??? All people had to do was prop within the stock motor limits but nobody ever seems satisfied with 1000watts or so.

Why didn't they just say whoa at what cans could be rewound? Keep it to the blue and yellow cans rewound??
