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.
Never heard of SPC.. Anyhow, look at rclipos.com,, Pat can help you with any new lipos you may need.. Great guy, only sells quality cells..
I dont like the KV rating of either motor suggested by Plett.. They will draw WAY to many amps in your application, and will stress out the batteries and esc.. What voltage did Plett recommend running it on? Any boat I have seen or built over 40" long has never had more than 850KV... Also 10S-12S is the standard for 40+ size hulls.. I dont understand Pletts recommendation?
Keep the KV low and the Voltage high, which will produce the torque needed to move that size hull, without pulling to many amps.. Which is what BURNS upesc's and overheats lipos...
Nothing like keeping you lipos warm and your prop wet!!Comment

It is not hard nowdays with all the good forums and information that is avaliable through the web.. Keep learning Douggie, I'm sure you will reach a point were your set-up decisions become second nature in making a selection..
I know nothing compared to some of the veterians out there like "Fluid" or Jay Turner... He has forgotten more about Fast Electrics than I will ever know!!Nothing like keeping you lipos warm and your prop wet!!Comment

Ok, I will call the canada pletten. dist. tomarrow and ask what the lowest rpm offered in that motor is. If I can get one 850rpm or lower I will do just that. I rc cars the spc site is well respected but this is boats so I will go to rclipos.com on that.
What size flex cable is typically used on motors of this size. I have some of everything in the book as well as any type of soldered hookups, stub shafts, and one piece cables too. I have quite a bit of speedmaster hardware too. With regard to props I have over 100 props of about every size. I have never traded any of my props away since beginning the hobby 31 yrs ago. I also own one of the best magnet centering balancing systems there is, a pitch gauge, prop anvil, and brass hammer so props should be less of an issue. Input on what works with this size of motors would really help on props.
I use pcm futaba radios. Don't want or will ever own a 2.4 gig system. Good crystals only for me.
Was the charger I provided a link to earlier up to this stuff??Comment

I go with 1/4 flex cable with a 3/16 prop shaft, OSE has them here...Speedmaster is the best IMO..

I think you should do what it appears you have already decided to do. You come onto this board and announce you know little about FE boats and ask for help. Then you start arguing with people about the advice you are being given.
For instance, you have a nice little charger. It will do up to 8S. But for your desired set up you should be running 10S2P. That is FOUR 5S packs. So with a single output charger plan on LONG waits between runs.
You got clear and well proven advice on motors. But you want to run Plettenberg. Then have at it. I cannot why you want to ignore the experience of people who actually run large boats, but it is a free country after all.
Sorry to sound so pi$$y but why ask for advice if you then turn around and basically question everything you are told?
I run both gas and FE, your gas experience will be great for tuning the boat, but EVERYTHING else is different.Don't get me startedComment

Fair enough on your opinions for the most part.
However, with regard to motors, well I have as much faith in the pletten as most of you appear to have in the neus. There is nothing wrong with being different. I notice from your avatar, that you run Deltaforce boats. THey are hardly as popular as say aeromarine, ac, rico, and others. However, you run them for a reason that you feel is important to you. THat is fine why should you criticize me for the very same type of thing. I have read your posts on JRCBD regarding the deltaforces and they seem valid, but they are not a popular boat in the US. Now around the world that is another story. Same holds true for the pletten motors.
That seems hypocritical to me, but hey a difference of opinions is what probably keeps motor makers in businessand deltaforce boats!! By the way I think you had some good comments on the dock regarding your preference of that boat. I own an aeroshark I traded for but have never run. Very similar to a delta force in many ways.
I was looking for specs from the beginning when I began this post. I finally got them, thanks to tex, and that helped me move to the pletten motor I was wanting to use. Same with the esc, no brand names rather specs and necessary capabilities.
I am a big boy and can make my own choices if I know what is needed. Enough on that!Comment

That seems hypocritical to me,
Specs are fine but especially in the FE world they do not always translate into actual performance. I merely shared what I know from actually running large boats with both Neu and Lehner motors and Schulze, Castle and Kontronik controllers. Same for the chargers.
When I have no direct experience I tend to seek out who does and follow their advice while on the learning curve. Mostly what people are trying to tell you is that they would hate to see you burn up $3,000 worth of stuff while learning. It stings far less to fry a $150 ESC than it does an $800 one. One last thing I have come to know, large boats are not generally the place to try to go economy. Get the best equipment you can afford and go have some fun.
Good luck and have fun.Don't get me startedComment

FE boats are totally different from nitro or gas where you only match engine & propeller. Here you have to match batteries & motor & ESC & propeller. If the setup is right from the first time you will love your boat and run without any problems. But if the setup is not right..... you can have burnt ESC and/or burnt motor and/or damaged lipos all these cost $$$
You have been given very good advice and if I was in your position I will follow it because some members here are very experienced which means that they have already been in your position and decided to try the FE from nitro or gas. You are a very experienced boater as well but I do not know what you know about FE boats.
I suppose that you have read the threads for building a reliable boat. In there it was recommended that for a boat like yours you can go with two solutions. Please note that what I will propose is not according to my experience because my biggest boat is 36" but according to other's opinions:
10 cells lipo, 600-1100 kv, propeller 61mm with 600 kv, 50mm with 1100 kv for between test
12 cells lipo, 550-900 kv, propeller 61 with 550kv, 50 with 900 for between test
The proposal that Mr.txboatpilot gave you with the 2215/2y on 10s, with x450-455, the FE calc program estimates 90-150 amps, 40-50 mph.
I know that running the above setups is very expensive. Here I will propose the bottom line which I believe that will work with very very low cost : 1000 kv, 8s (1p or 2p), x450
Motor : KB 45 11XL (1000 kv) http://www.offshoreelectrics.com/pro...php?prod=kb-45
ESC: hi model 200a http://www.himodel.com/electric/HiMo...-200A-BEC.html
But you have to add water cooling and waterproofing
Batteries : 2 4s in series (8s1p) but must be able to handle 100 amps, or 4 4s, 2 in series and 2 in parallel (8s2p) each bat. to handle 80 amps
Prop: x450
You can try the above first and if not happy, go the expensive scenario.Twin Cat 135, Sprintcat40 (single-twin), DF 35", Maritimo, Mean Machine, SV 27

One thing I forgot to mention is if the KB 45XL can actually work on 8s, I do not know, please ask OSE.Twin Cat 135, Sprintcat40 (single-twin), DF 35", Maritimo, Mean Machine, SV 27

Curt I have both the Plett 300/50/A1S and Neu 1527/1Y and I have to say I personaly would go with the Neu motor because it is half the price of the plett with more eff% and better performance . Neu.s are every bit as good as the pletts and cost way less with better performance . I have 5 pletts , 2 Neu 2230,s 1 Neu 2220/1.5Y Custom build , A 1527/1Y , 1515/2.5D , Lehner 3080/7 not to brag but have compared them all and just find the Neu,s more powerfull for a lot less $$$$$ . I have a 1/8 buggy and have run a plett maxximum back to back against a Neu 1515 , both motors are around the same size and same weight but the performance of the Neu was clearly better in fact more than noticably better
Also 40mph is easy to attain in a 47 inch hull . My stealth will do 75kph on just 6c2p5000,s , weigh,s 25lbs and is 48' long . Its a 2230 powered boat that normaly runs 10-12c
Dimitrios I would go with the new Feigao 580 before I would the KB45 , the KB is a piece of crap..........

Beautiful run.
So you run 6s2p,right? ESC? Motor kv? Propeller?Twin Cat 135, Sprintcat40 (single-twin), DF 35", Maritimo, Mean Machine, SV 27

What setup on the video? Motor, esc, batt's, prop..
