New To This Site / Have a Few Questions

[crrcboatz]

Steve,
tnks for the post. I would think that just as in gas boating there are many good and proven engines, zenoah, quickdraw, jg, and the new rcmk engines. In nitro there is nova rossi, osmax, rossi, cmb, and the andy brown engines.
It seems odd that the neu would be the only proven motor in rc electric. If you can give me the specs. on the neu motor I need I will match those to the plettenberg line and probably get one. Also specs on the speedcontroller necessary to handle the neu motor. I have never been one to consider only one line in anything. There has has got to be more than one way to do this. It is a world wide hobby and there must be vendors with proven products for a customer to consider.
I don't buy cheap stuff. Never have and never will. Quality and reasonable cost is the backbone of the free enterprise system. I simply do not have the knowledge in terms of specs to know what to buy. Provide me with those and I will do my own shopping if that is necessary.

I own 16 boats at the present. When I raced I had more than that. I buy and sell stuff too. I have smaller hulls that would fit the bill for electric. I have a lite layup 31 inch fiberglass cat, a Aero. Lam. 34 inch titan, and a epoxy 33 inch dv all that would be a good starter boat. I just have a special fondness for the prather epoxy hull. Had it for several years and was looking to find the right project for it.

If you can provide the specs on the esc and motor for the 46 I would appreciate it.

The big LMT's have been the staple in big RC boats for years, the Neu marine motors are fairly new to the market (all things considered) and are proving just as capable. If you go the Neu route, then this site is basically "one stop shopping" for everything you need.

No need to look elsewhere.

A Douggie moment

Sir, for a first time possible convert to FE boating. I am astoninshed that you have not viewed this site and others with your prior knowledge of model boating, Are you pulling our chain???

Pletty motors are some of the best in the world. German made and they have a complete line of marine motors too.
What are the specs of a motor I would need to get they epoxy offshore to 40mph? I am not looking to go 60 this boat will not handle it. As for the weight of this hull. I have had many fiber glass hulls that are light layup in my hands over the years at boat races. This hull is lighter by a mile than a light layup. Weight well I would need to get it out of storage, openup the new box and weigh it for you. Lets just say it is lighter than any fg light layup 46 inch out there

Personally I would go with the Neu 2215/2Y on 10S2P 10000-12000mAh total, esc's I would chose between the CC HV-180 or HV-240 either will do for a 40mph sport set-up,, or MGM 12545-3 or Kontronik PowerJazz 120/63V.... All are very nice controllers under $450.. If you want to try a cheapo-esc, look at the 100A Turnigy HV 2-12S lipo esc at unitedhobbies, it is only $100 and you can add cooling to it or a fan..

I cant comment on the plett's as I have never owned one. But I have heard nothing but great things about them..

As for lipos, I would get the best your money can buy!! They are the heart and soul of a "quality" brushless set-up..

Good luck with your build!

As for motor specs, its up to you. Look for a motor that will give the number of watts you need. 746 watts equals about 1hp. You are probably shooting for 4-5 hp. Neu has been building some incredible motors.

The Neu 2215 and 2230 series motors are incredible beasts. Producing upwards of 10,000 watts!!!

Douggie

why would I be pulling you chain??? I am retired and love to work on my boats. I am simply looking for the specs. I am quite aware of the neu motors in a car setting. However there the plettens absolutely eat them up and are much higher in cost. The pletts quality is of the highest order. I like you would prefer to stay with something I have known. If I get the specs I can match a pletten. to the neu and see what else is out there.
I have been a member of Jims rc boatdock since 01 and am the 900th member out of 3000+. I hope you would not question me as a person or question my character! I have not done that to you sir.

[Flying Scotsman]

I am not questioning your character. You come out of the blue with basic questions as far as FE boats are concerned...Learn Laddie and I trust you enjoy the hobby.

Specs on the 2215/2Y are 750KV, 30,000RPM max, 24oz, 8mm shaft, 3000-5000 watts...

[crrcboatz]

I now have neu motors site as a fav. . The 2200 series is a 50x68mm size motor.

The pletten. motor that is closest to it is the 300-50-ais. It is a 50x80mm is 1420, or 1200/v. It comes water cooled and sells for $465. I is a 5mm not the 8 like the neu has so there is some differ. there.
I also found a mgm tmm 22418 that is rated at 224amps cont. and max for 10 sec at 280. Sells for $239. watercooled acc is 19 bucks and I must install it my self. They also have the 22412 with the watercooled installed for $159.

I am going to try the pletten for that price because it comes water cooled and is a larger motor than the neu.

Which esc of the 2 mentioned above do you recommend? They would need to order the 418 and takes 10 days to get which is not an issue. They have the 412 in stock.

Sounds like a great motor choice.. Where are you buying it?

The esc's you have mentioned will not do over 6S lipo on the 22418 and only 4S lipo on the 22412... The 12 and 18 #'s represent the number of cells it will handle..

Look at the 12032 MGM, if you are going through i-care, they can order the watercooled schulze 40.160 for a good price. They have the air-cooled version in-stock for $499..

[crrcboatz]

How many cells do I need for sport purposes? I plan to connect 2 11.2 3s lipos in series to get 22.4 v total. they are either 5000 or 8000 each in the mih rankings. I don't know the first thing about the math formulas you all use to come up with the #s you use.
Could you share those formulas with me for all necessary computations, battery, esc, motor output?

Thks Tex.

The 2x 3S packs for 6S will NOT do it,, you will need to double that, at least.. Meaning 4x 3S packs 2 in series and the pairs in parallel connected to the esc..If they are 5000mah cells that would give you 12S 5000mah total,, the othe would be 12S 8000mah, this would be much better.. Are the cells 20C, 25C, or 30C discharge rating?? Lets assume the are 25C,, the 12S 5000mah would be able to discharge at 125Amps cont... The 12S 8000mah set-up would be able to discharge at 200Amps cont. with out any overheating or damaging the cells.. Every 40"+ boat I have ever seen or built, runs at least 80-100amps cont.. even for sport running at 40mph...

The voltage you will need is detemine by the KV rating on the Pletty you will buy.. If it is 750kv for instance,, on 12S lipo (44.4V) you would have a "un-loaded" RPM rating of 33,300.. Math 750kv x 44.4V = 33,300.. You do not need this much RPM for a sport set-up, I would shoot for around 22,000-27,000rpm unloaded... This means you need to change either the KV rating of the motor of change the voltage, which means getting different lipos...

I looked at the Pletty's.. I would go for the BM370 series...

Hope this helps..

[crrcboatz]

Wow, you are a wealth of knowledge!! Love it. I can get the 300-50 in either 1200rpm/volt or 1600rpm/volt. I would prefer to use this motor as i called pletten. and they recommended it.

Now with the increased rpms and the formula used how do I use that to determine the proper batteries? They are 25c rated. Also, I am open to those who sell batteries. I use SPC to buy my batteries at this time. The gentleman is an electrical engineer and personally tests every lipo he sells before shipping. Prices are pretty good and he seems to have a wealth of knowledge like you!
Anyway always open to a new vendor though.

Curt, please start small in your aspirations. You are not going to be happy when you blow up a $500 ESC. PS I am an OLD FART also and count my pennies!
