A word on Rc Boat Propellers

[@RDM3DLAB]

Great video this helped me out a lot thank you for taking the time for us!!!

[@ManCaveTVWest]

This is the only video of it's kind! Big thumbs up!!

The pitch of a propeller tells you the distance it travels in one revolution . So over say 1 metre metric or even 1 yard imperial measurement you can calculate how many times it has turned. The greater the pitch the more distance in one revolution , it's the same as full size boat propellers , both standard and race props . If you ask a person who races big boats it may help. But not forgetting your boat is a scaled version of a full sized boat and so to is the speed. Hope that helps Cheers

mono hulls need lower pitches. High pitch props are for flat bottom boats like outriggers and hydroplanes. generally 1.6 is as high as you go with a mono. 1.4 being best. Higher pitches lift the transom and will cause a mono to become unstable.

Great break down on the props! Very educational video!

[@jmoe2060]

Thanks for the great video and for sharing your knowledge. First time on your channel, but I'll be back. As an aside, I must say that Impulse looks awesome with some of the graphics removed. So much cleaner!

[@dimalranasinghe8152]

Thank you very much.

A lot of good knowledge being shared here. Big B @ironclad rc told me about your channel. New subscriber here

[@mad_lizard]

Awesome, thank you!

[@norcalrc]

@@mad_lizard for sure. Your content is great bro

[@nossrc5638]

very good information and well explained 👍👍

[@anthonybutler2741]

I just put that 48 mm prop on my Impulse haven’t run it… you think it’s too much?

[@911dott]

Great video!!

A good break down of pitch is to compare over a distance. Say we are talking about going 10 inches. A 1.4 pitch will take 10/1.4 = 7.14 rotations to go 10 inches. On a higher pitch like a 1.9, 10/1.9=5.26 rotations to go 10 inches. So in theory it takes less rpms to go the same distance thus greater top speed if your motor reaches peak rpm with both props. To relate this back to your motor you have to consider its rpm/v rating. Lower rating will have more torque and be able to turn a higher pitch versus a higher rating which wont be able to get to full rpm potentially. at some point too much pitch slows the motor rpm peak down so you will start to go slower, create more motor, esc, battery, and wire heat.

[@palehorse7377]

pitch also lifts a boat. so you cant just slap any pitch on any hull. mono hulls want low pitch. hydros want higher pitches.

[@Griso12008V]

What is the stock prop specs for the impulse 32? I know it’s the same prop that comes with the Blackjack 42. I have looked all over and have been unable to find the info.

Ciao amico ! Come stai ? Senti, un bel video! Scusami, dove compri questi elica? Mi consigli per favore per il mio ProBoat shockwave ? Anzi, secondo te,cosa meglio, plastica,alluminio oppure rame ? Grazie mille. Ti saluto da Italia ! Eugenio

[@mad_lizard]

Grazie. im negli Stati Uniti, quindi l'inglese è la mia lingua principale, quindi sto traducendo, quindi abbi pazienza con me. il metallo è migliore e può sopportare più carichi di stress di uno in plastica. l'acciaio inossidabile sarà la scelta migliore per la forza. l'alluminio va bene o il rame/ottone. Non conosco la tua zona ma qui ci sono alcuni posti. ebay, Rcbb sono fuori dall'Australia, Dr props è in Russia e ci sono alcuni posti negli Stati Uniti. ala hobby, TFL. Cercando su Google nella tua area generale potresti trovare buoni risultati. su facebook c'è un gruppo chiamato RC proboats. buon gruppo e io ne faccio parte e puoi trovare molte informazioni e altre persone che potrebbero essere nella tua area generale che possono aiutarti per le risorse.

[@eugeniotkach1564]

@@mad_lizard Grazie amico per la tua risposta ! Guarda, non ho visto in vendita di acciaio.... sarebbe molto meglio di tutti! Ho pensato comprare qualche di alluminio, perché ottone mi sembra molto morbido e può diventare scuro, tanto, noi abbiamo acqua dolce, laghi. Ma secondo te, che diametri più preferiti? Adesso ho 41 mm. Tanto, non ho esperienza con barche, prima avevo solo drone. Grazie mille amico! Ti saluto 👋

[@mad_lizard]

@@eugeniotkach1564 peut-être essayer un aluminium 4214. ebay pourrait en trouver un. venez découvrir RC proboats sur facebook. si vous publiez un message, vous pourrez obtenir beaucoup de commentaires et je peux intervenir pour vous donner un coup de main. en particulier, je peux déterminer ce que le bateau utilise pour l'électronique et déterminer quelles hélices utiliser.

[@crisppyy_bacon3784]

As a recent graduate of naval engineering, when he said there’s no math involved in propeller design… I visibly cringed 😂 great video tho very cool stuff

[@mad_lizard]

As keeping the video basic to a lot of new people coming in to the Hobby technically there is a math equation to propellers and their design. This equation can be factored on your variables of the boat. Rpm, volts , torque, hull type, efficiency percentages and weight. Diameter, and pitch and slip. Now there’s probably way more in equations to factor propellers but keeping the video of information for the new people coming into the Hobby and learning. Graduating naval engineering congrats on that.

[@crisppyy_bacon3784]

@@mad_lizard you're right, lot of factors take place in prop/hull design, its a fun field. by the way i was of course joking when i said I cringed, I thought this was a great informative video!

[@meandmylandscapes]

Very useful video 👍

[@mad_lizard]

Thanks a lot

[@ronchang9791]

In rough water with heavy chop, boats can rarely use more than half throttle. In those cases, would we be looking to go down in diameter or pitch as our first move? Thanks for the informative video!

[@palehorse7377]

mono hulls can if you set them up right. postive stinger pitch with heavy negative trim tab.

[@Shuko88]

Any advice for the best props n batteries for a sonicwake v1.

[@hoodatdare7039]

NOW I KNOW, THANKS.

[@IRONCLADRC]

Hey I have a couple of subscribers asking about high lift v/s low lift propellers I'm gonna make a video of the 2 differences and I was wanting to ask if I could link your KZbin video with my KZbin video because you got a lot of great information in there that would really help out a lot of guys so I just wanted to ask your permission before I linked your video

[@mad_lizard]

Go right ahead. I don’t mind at all and if it helps other people out in the Hobby that’s awesome.

[@IRONCLADRC]

Yeah that's awesome man thank you very much I'll finish the link when some finished up with the video

[@mad_lizard]

@@IRONCLADRC cool, looking forward to see this video.

[@dalegunning7378]

What would I put onto a Traxxas Spartan

[@mad_lizard]

I would try a 4214 for that boat

[@carlosmonteagudo5678]

Great video super disappointed no one talks about the 3 blade props 🙁

[@mad_lizard]

Any prop information is hard to find regarding to any information on them. Ironclad made a few that are pretty good. You will find in the boat hobby propeller information and how to are held onto by people as holding the information as a Secret
