[Nitro pilot]

Just want to say hello to all. So I just built a fiberglass 38 inch deep v hull boat. Imm an old nitro motor guy. So now I am stuck. Curious if you guys could point me I the right direction on what I need and brands of what to purchase next? Servos, receiver, controller, speed control. Also, a fast brushless motor. Hoping to get around 50, to 60 mph out of it, if that's possible. Thank you in advance for any and all help.

Hey nitro I’m also a new guy here and not as smart as some here but intelligent enough to give you some pointers. Brushless is great to have for that quick bashing and running when you want to go out and have some quick fun. Gas and nitro as you know needs a bit more hahaha. A trailer a tuning kit and tool chest and a place where Karen or Daren will not make a noise complaint to local authorities. I’m kinda exaggerating. As for running gear I run spektrum receivers and servos. I also bought the spektrum transmitter that holds 20 boats so you are not carrying around all those controllers. I have converted all my nitro and gas boats to that brand which is a lot better than the stock gear. The brushless got me into that being proboat that uses all spektrum smart tech which is hands down easy for a newbie like myself too. As for brushless motors I don’t know much about those. Now there will and can be millions of answers and ideas to do by others. I just like to be a person of simple straight forward fun. I don’t race and not in any teams that do. I have had friends that do this also and say why don’t you join or race your collection you have? I just say I like to take it to the mystic river at boat club drop it in the water and play with the kids for about an hour and that’s my hobby and enjoyment. Don’t be shy let’s see what your deep v looks like. Curious.

If you are not racing, then you don't have to go by the rules.
In general for FE, heat and loss are the enemy. So, when selecting a system, I recommend the highest voltage system you can.
Power = Volts*Amps,
Power dissipation = Amps^2 * Resistance,
So, double the volts, half the amps.
Probably 8 -14S arrangement.

Batteries:
They are nearly always the weak link in a FE arrangement. Boats pull a lot of amps.
I recommend SMC racing, the HCL-HP or HCL-HV Flight packs are proven winners.

As someone else said, it depends on if you're trying to conform to a set of racing rules or not. Either way, the ESC/speed control you'll want for that boat that will do anything you ask of it is a Castle Hydra XLX2 https://www.offshoreelectrics.com/pr...as-010-0173-00

Servo's, I have good luck with running these in almost all my boats https://www.amazon.com/dp/B07SBYZ4G5...n_title_1&th=1

Radio (transmitter and receiver) is up to you. Typically can't go wrong with Futaba, but they're expensive. I run an old Flysky IT4S in all my boats, but it's discontinued, so I'm not much help there.

For the motor, it'll depend on if you're trying to meet rules or not. Basically, will the boat be on 6S or 8S configuration. In my 40" mono, which is a racer on 6S, I run a 1520kv TP Power 4080SVM motor. You could achieve your speed goals on 6S with a cheaper 1520kv TP Power 4070 motor, or on 8S with a 1090kv or 1220kv TP Power 4070 motor.

As for batteries, if going racing rules at 6S, I run a pair of these in parallel. https://chinahobbyline.com/products/...11be9999&_ss=r
If not worried about max voltage and going for easier 8S, you could run a pair of these in series. https://chinahobbyline.com/collectio...-with-qs8-plug

because boats pull so many amps compared to planes and cars, batteries only last about 90 seconds. It is common in racing to pull 200+ amps. some as high as 300 amps. If you slow them down to basic, stock low % nitro speeds you can get maybe 120-150 seconds.

electric boats will never ever keep up with nitro past the first 5 seconds.

I recommend going to gas boats. They are bigger and handle a wide variety of water. They are cheap, lightweight, and extremely easy. a gas engine weighs the same as a single large battery pack and the whole power plant costs under $200. a gallon or two of gas will last a whole year, you dont have to charge batteries all day, worry about lipo fires, there's no taping, they cant sink because they are large and lightweight, the wood hulls and hardware are the same price as a small electric boat.

BOLLOCKS!

Didn't you read the part where the op isn't racing. It is absolutely possible to make his hull run for 5 mins at 50+ mph without spending a fortune.

Bande why do you even bother commenting and trying to turn people to gas. You may have decided to prefer gas/nitro, but that isn't the preference of pretty much the vast majority here.

[CJPB32]

I run my RTR Impulse 32 for about 7-8-9 minutes on 6s with a top speed of 54-55 mph on smooth water at our lake (I finally bought a gps top speed recorder). I run big circles around our pontoon using 8 sets of 3s batteries usually taking a cool down break after using 4 sets of batteries (maybe take a break for lunch?). I grease the shaft at home the night before and never re-grease while running. No problems so far....

you cant be serious? Nitro dominates the 2 lap record books by a mile.

Only electric guys are bothered by stuff like this. Its as if you have to cling to one type of power plant and nothing else can ever compare. Like a weird cult.

normal people dabble with all kinds of boats.

7.5 minutes at that speed would take around 30,000mah. Battery runtime is really easy to calculate. for example at 55mph you should be using about 2500w / 60 minutes is 41.6w a minute. A 6000mah pack has 133wh. so take 133wh / 41.6w per minute = 3.19 minutes / 2 for a 50% drain = 96 seconds runtime.

what you are probably confusing is that runtime means full throttle use. When you run a boat you never, ever let off the throttle. when you corner you are supposed to be holding full throttle. you are certainly playing about with partial throttle the vast majority of the charge and calling that your "run time."

[CJPB32]

For me, run time is certainly NOT continuous full throttle which is why I wrote "top speed" of 54-55.
For me, it's running the boat around our boat while our 10 LB dog runs back and forth having a grand time barking and chasing it. At the end of the day she is exhausted and sleeps all the way home from the marina.

I am certainly at partial throttle with s-a-w bursts. I'm not racing or in any hurry to drain the batteries. The longer the run before a battery change; the better. It's a fun toy.

exactly. most boats are made to run an oval course. That is where the painstaking engineering of the hull, turn fins, setup, motor KV, props, etc are all geared around. The people designing them put all that time and effort into them so that they can run laps. why do you think they water cool the motor?
