Detounge Sharpen and Balance RC Boat Props

This is a video on how we detoung, sharpen and balance our metal RC boat props to get more performance. Also includes test runs and speed clocks with one of these props on my BlackJack 26 with the stock power system.

Hi, I am not speak english good but I hope to anderstand me, ok ,my qestioni is how diameter are the propeller of boat, because I order to HOBBYKING and I hope it's delivery to me in next weak because I want to change the original. Thank You !

@JANCSI1978 the prop is an Octura X442 and is 42mm. There is a link in the video information bar to Offshore Electric web site. You can buy them there.

Hi Frank, Great video...i sharpened and balanced my first 440/2 blade octura last night...I am not sure why detouge is important...can you explain the difference between two of same props,but one is detouged and other one is'nt...thanks

[DiehardRCaddicts]

@roadstar499 Detounging the prop makes a noticeable difference in performance, usually good for an extra 3 to 5mph. Detounging the prop gives you a little better pitch ratio as it removes the part of the prop with the least amount of pitch. It also takes some of the load off the motor allowing it to rev higher and faster. Also because of this you can usually run a slightly bigger prop. I went from the stock 40mm prop to a 42mm prop. All this equates to more performance

@DiehardRCaddicts Thanks frank... does it increase hole shot response also..? and any effect on cavation? thanks i will order that prop for my sv and surge crusher 42mm and detouge or get that prop you said is the same as 442/2 from octura already detouged...thanks a bunch for all your expert advice

[DiehardRCaddicts]

@roadstar499 leaving the tounge on the prop will give you a little more bit on the lower end of the throttle range but will limit top speed. Going up one size in prop diameter when detounging will make up for this and give you even more speed. If you saw my Black Jack 26 in the video, It was still running the stock power system and didn't seem to have a problem with cavitation.

Thank you wery mutch !

@toddawdirect look in the description; stock power system

[evanzapata]

how much does all of this stuff for it cost all together

[DiehardRCaddicts]

@streetforcegp2 it's easy but can be time consuming. You just have to make sure when the blades stop spinning on the balancer they are both parallel to each other and level. Neither one should be rotating to the down position. You have to get it as close as possible during filling and sanding the prop blades. Then finish up balancing with some fine sanding emery cloth and water when in the polishing stage.

[streetforcegp2]

can you explain how do you go by using the prop balancer? thnx

[DiehardRCaddicts]

@dtmpowerboss "offshoreelectric" online store has a large selection of props. They also have carbon props which cost a lot less than the metal ones and don't need to be sharpened or balanced. Again look for one around 42mm in diameter.

[dtmpowerboss]

@DiehardRCaddicts ok thanks a lot do u know where i can get thouse am looking for cheaper one

[DiehardRCaddicts]

@dtmpowerboss the Octura x442 is a great all around prop for 36mm diameter motors between 1600kv to 2000 kv. You could also try the Octura x642 for a little more speed if your motor is rated over 1000watts of power. Its the same diameter only with more pitch.

[dtmpowerboss]

hey which prop do i need for spartan i got 1800kv motor 4 pole and 180 A esc let me know if you can help thanks

[DiehardRCaddicts]

@toddawdirect that would be the Fuller's Fast Electric Catamaran Hardware. You can find their e-bay store if you search under "Fullers Fast Electric". Their products are awesome and they are always very helpful and quick about getting back to you. I'll send you a link.

[toddawdirect]

what hardware are you running on the blackjack?

[spencermel]

@DiehardRCaddicts Thank you for the feedback,so brushless is the way.

[DiehardRCaddicts]

@spencermel long before the electric stuff caught on I was into fuel powered cars and boats big time! They were a lot of fun and pretty easy to tune and modify. I got away from fuel and got into electric when brushless power systems started to come out. Fuel is great if you like long run times and can find a place to run where the noise won't matter. Electrics these days are as fast but run quieter and cleaner with shorter run times though. Cost between fuel and batteries are about the same.

@DiehardRCaddicts Thank u so much, Frank :P

[startazz]

Great how to Frank and man that boat was going some ;-) nice one mate and thanks for sharing = thumbs up.

[spencermel]

@DiehardRCaddicts are gas ones difficult to dial in?I mean,I like the electric but i would need like 5 batteries to get my fix.I know you're a electric guy.What do you think of the gas ones also.

[DiehardRCaddicts]

@RFTAEC100 It would make a noticeable difference, usually good for an extra 3 to 5mph. Detounging the prop gives you a little better pitch ratio and also takes some of the load off the motor allowing it to rev higher and faster. Also because of this you can usually run a slightly bigger prop. I went from the stock 40mm prop to a 42mm prop. All this equates to more performance.

[DiehardRCaddicts]

@spencermel it's definitely faster with the new prop. RC boats are a blast to run!!! I'm sure you would enjoy it!

[RFTAEC100]

Hey, Paul! I have a shockwave 36 completely stock, would this make a great difference in performance?
