Flex Cable Failure & Potential Causes Rc Boats - Proboat UL-19 Broken Flex Cable

[@jefferyferguson9232]

P.S. your channel is far the most Informative and instructive out there. Keep up the great work.

[@IRONCLADRC]

Thanks brother, glad I can help..... thanks for watching

[@frederickgrassie3383]

Thank God you showed how to remove broken flex shaft. Did l8ke you did, had to remove strut, cut off the teflon tubing, and had to cut off the flex ahaft to remove through the strut Thank you Big B

[@leddiablo101]

I cant believe you knew what it was immediately. You certainly know your shit man

[@peternaake2032]

Hey, thank you very much for your very informative and entertaining videos. I'm a beginner and own a Joysway Rocket v2 and had no idea that the teflon liner was not supposed to move! A while ago the tube moved towards the motor after greasing the flex shaft. Just moved it back and thought nothing of it. Right after this video I scuffed the tube and used super glue to fix it. You saved me from a lot of trouble due to ignorance on my part! Thanks :D

[@IRONCLADRC]

Super glue works and red lock-tite, you get the best results with the grease completely removed

[@cyclonerc1625]

That UL-19 is Sweeeet looking boat. Can't wait to see what it does with that new cable. Thank's for Sharing Big B 💯👍👊✌

[@IRONCLADRC]

Yea man with the extra power it's a much needed upgrade. 👌

[@garryhodgson2614]

Loving your channel big B. I am running a joysway alpha got loads of tips from you bud on setting it up it's running sweeeet now top man big B👍

[@IRONCLADRC]

Those are nice boats build it ironclad, Glad I could help brother. Boat gang

[@h2omechanic]

30 secs before it broke, it sounded louder than normal. It was spinning the liner probably. Mine did it too. I just installed a 3/16" cable last night in my 29. .150 cables cant handle high rpm & big props. Fine for 4s just not 6s. 3 of my boats don't run liners bc of this same thing.

[@IRONCLADRC]

150 cables will/can handle 6s power and big props in lightweight boats.

[@jefferyferguson9232]

Sorry for your breakage. But glad to see it. Sorry, but your video kept me from breaking mine tomorrow. Running the same motor as you 200 amp seaking, 2 5000mah 120 batteries. Just received a 48mm cut down to a 44 with a good cleanup and thinning etc. If it wasn't for you I know I would have destroyed the shaft. Tried to order the upgraded shaft from Ose. Backorder...sorry again, but thanks. 10 second Jeff..

[@IRONCLADRC]

This cable will work this is what I'm putting in mine. Just have to cut the cable to length www.offshoreelectrics.com/proddetail.php?prod=ose-cable-1190

I have my old joysway surgecrusher it is a 24'' cat i used to love so much... last time i ran her was 10 years ago... I remember i ruined batteries and smoked a few esc's before i got her right... last setup was 4-5 s using 120 amp hobbywing boat esc and a 36-60 1900kv out of my motley crew boat... i had changed the stock 5mm flex to aquacraft 4mm which ended up breaking wear the solid steel connects to flex...Anyway i actually found the old 5mm yesterday which is very solid still...not sure why i changed in first place... I popped out a brass sleeve out i had put in when i change to 4mm ...the deal with the stock 5mm is it has to been installed from the front since it has solid maybe 5.5mm 2.inch steel before it tappers down to 5mm where prop is... so i have to remove drive dog and install from front... i think this i why i changed it,but actually its a good setup since if flex broke the prop has no way of falling off...My question is have you come across similar flex drive designs and what do you think?? thanks again for helping me figure out the best rc boat fixes... Happy boating!

The UL-19 is my first and only RC boat. I just put together a 2 man raft. Made a wooden carpeted floor, stool with hinged top for storage, motor mount with small utility table for putting the RC boat on, and a 46lb thrust trolling motor. My 12v battery will be here today or Monday then I can take my boat out for its maiden! Well both boats out for their maiden :) plus I'm gonna do some fishing from my raft while I'm out..

I’ve been running OSE 187 cable for a year now with no issue in my UL

[@IRONCLADRC]

.187 is the way to go. I've never spun/broke a .187. Cable.

[@hoofarted8709]

SO FAR i like using the shaft liner...i lubricate the drive shaft properly and after i install it into the motor or "callet" or whatever i lift the bow and use a dropper with synthetic oil in it and put it on the shaft that is exposed just before the "callet" and then i pick the boat up and hold it with the bow pointing to the sky and rotate the shaft so that the oil will run down the shaft...i dont know if it helps but after i had my shaft get hot at the motor i started doing this and its been cool ever since:)...just like Mathew Mcconahay said in daisied and confused "hey man do you have a joint on you"..."well you would be a whole lot COOLER if you did"...lol!!!!!

[@IRONCLADRC]

Yea man it helps with a drop of oil in the tube I do that with several of my boats I've noticed a considerable difference in sound and vibrations..

[@Abdelshafyelkomy]

Big like to see you my dear friend 🙂

[@xillianto]

i think this is what has been happening to me aswell, thats why i am going with brass tube only

[@georgem.6136]

What’s the easiest way to remove Teflon liners you think, Cause some can be a bitch

[@IRONCLADRC]

I like to use a tight fitting drill bit in reverse should spin it right out

[@georgem.6136]

@@IRONCLADRC Thanks Brother!

[@nsvaluto48328]

Big B, I don't know if it is this video, but there is one that you discussed unwarranted water entry in your boats. specifically a silicon tube over stuffing tube to prevent water entry at motor coupler end. I need some suggestions on that when there is not enough room between coupler and end of stuffing tube.

[@IRONCLADRC]

Hmmmm not sure what you could do there? Make sure your shaft is tight in the strut! Alot of times water will enter thru the shaft/strut. May need a new shaft or strut or both. I don't know with out seeing & looking at the boat. You could always trim a very small segment of the stuffing tube to accommodate the silicone tube. But not to much? Hope this helps. Just throwing ideas around

[@nsvaluto48328]

@@IRONCLADRC thanks I will consider all ideas right now I tried a second bushing in the motor end of the stuffing tube. Unfortunately I tried seating one end and the other end pushed out may have to trim the one to the point where it does pust out.

[@jamesstuarttolford1978]

What got to be done to discard the liner? Please advise. Thanks

[@berrymucuckiner4890]

Regardless of heat and strain on the motor… Does forward CG typically give better speed and handling?

[@IRONCLADRC]

On these hulld CG needs to be at the back of the turn fin. Forward of turn fin will hinder its turning abilities

[@roadstar499]

Is a.187 cable bigger than a 4mm cable? and what is the stock cable size for this boat?? to me it seems around 4mm... I am only familiar with sizes 3.17mm 4mm and 5mm ...thanks again ...this is a great video btw...

[@IRONCLADRC]

Yes sir .187 is the same exact size as 3/16 which is 4.76mm

[@IRONCLADRC]

.150 size is 3.8mm. I use Google to convert .150" to mm = 3.8mm

Need yur help. My sr80 has very slow speed after I change the motor and esc. The new motor is turnigy 3674 2200kv and seaking 180a. Do u think the drive shaft or something is wrong? The engine rev is amazing but dont know why the speed is too slow.

Weight. It may be to heavy. Boats like to be light

[@Otis5115]

What size coupler is used for the stock shaft? I’ve bought a couple from ose and Oxidean and I keep getting the wrong ones 🤦🏼

[@adamcrazski]

Do you feel there is extra wear on the stuffing tube without a liner?

[@IRONCLADRC]

Not yet? I keep her greased up.

[@adamcrazski]

Thanks buddy. I'm currently upgrading my ul19 and veles. I will be receiving my new power systems today. Sss4074-2200kv with seaking 180's and 42mm x 1.6 cnc props. I went with the upgraded .150 cables instead of the .187 because I was worried about wearing the thin copper stuffing tube without a liner. Have you used this system combo yet in either or both models? If so what was your experience? I appreciate your videos, they helped me a ton on the little niche things with boats that I haven't experienced with cars, planes, or helis. Lol! Your mono tuning video saved me with my sr80 pro.

Hey Big B, what motor your running in that boat??

She caught some wind and flipped, both fins broke off. They don't float, & I lost one. Tip! Fill wings with foam 😆

[@dylanhefferon415]

is there any advice that you could give me on my veles? Like drive wise and anything else? I also put a water pump in it.

[@IRONCLADRC]

Ose sells a "HD" flexcable that would beef up the driveline or run a .187 w/o the liner.
