Revolt flex shaft problem

[Doby]

Hello Doby
The problem with that is the props and prop shaft are on the bottom of the lake.

OK,,,then that creates a bigger problem!!!!!

My opinion is that's not the proplem only because one of the flex shafts was mine i ran it 10- 15 runs in my boat with no issues when we put it in his revolt 2 seconds and it was gone. Something else going on here. Not to mention an expensive issue when you calculate the cost of 3 sharpened and balanced props and the flex cables.

I've had a bushing that liberated the props from my flex shafts....is this using the same bushing?
If not...
I think at this point I'd remove the strut and inspect it, then pull the tube/liner and replace it....
If you have the gumption, this would be a good time to lower the motor and move it aft....I picked up a little speed and performance with about 15 minutes of cutting and grinding the original. I was also able to move my packs a little further aft and carefully align the shaft/motor.

Also going to add that the revolt is brand new and has a total of maybe 15-20 seconds of run time. For it to go through 3 shafts in that little time something is !#%# up. I would be pissed if this was my first boat. All that money and boat has went 50 yds!!!!!

Like I said before all three cables broke right where the flex meets the prop shaft.

Oops... sorry... I misread... I thought it was at the top of the suffing tube.

Are you getting the bushing lubed well enough in that area? I've had them come apart there when they got heated up on the teflon and the material weakened. Put the shaft in without the motor in place and make SURE it is free of ANYTHING extra rubbing on it...

If this is china manufacturing then question solved. Get a good one built by one of us..or ed hughey but this would not be the first of crap shafts made by them...just being real here.

Did you buy the boat new? If you did I would contact the place where you bought it. You should be able to return it and get it replaced for free. There has to be a serious misalignment to cause this to happen.

In all fairness... I've been running standard Pro Boat flexshafts in almost all of my Pro Boats, and even have one in my P-Ltd Hydro, and haven't had one fail yet.

It's usually NOT the shaft... It's usually something rubbing ON the shaft...

All that said... Jeff IS right about ours being "better"... The mass produced ones aren't generally as "true" and are usually of an inferior metal.

Make no mistake, it's a manufacturer's defect.
I recently purchased two Revolts for myself and a friend, and on both boats the shaft fell off of the flex on the first run. I replaced them with aftermarket flex shafts and they have been fun little boats ever since.

It must be the latest "batch" of boats/flex shafts that had this issue.

That always sucks... Guess it's something to keep an eye on.

Hello keith and darin
I have checked this boat out from top to bottom. There is nothing out of wacke. I did mic. the flex shafts and they are all different.
I did buy this boat at tower hobbies. I talked to there service department and they said they had not heard of any flexshaft problems.
Tower was good about it to send me two new props and two new flex shafts. Flex shafts are on back order. Bottom line I ordered
a hughey.

I had lost a brand new m445 on my Pursuit because the previous owner had a AC cable in it, not knowing at the time, lesson learned. All the after market flex cables sold here at OSE and other sites are good products, had no problem so far. I had Jeff made two for my Pursuit, BTW.
Having said that, I had my Proboat stock cable in my MG with a 4082, 2200kv motor and had no problem, but since the Pursuit incident, I changed ALL my cables to after market ones!

a hughey.

Your problems will be gone. The factory flexes were just improperly glued.
For any onlookers to this thread, OSE sells a pre-cut, drop-in upgrade flex shaft for the Revolt. If you replace it BEFORE your flex failure, you wont have to replace the prop too.

I am glad this came up the other day when I was looking at mine I thought it looked like the flex cable was moving slightly in the shaft but then I thought I was trippin lol... I guess here is my sign..

I have also got caught grabbing an AQ shaft at my LHS to "get back out" and poof,25ft gone with my 645 prop. ALL my .150 glued cables are still in use today. The 3/16 ones are all from Steve and welded.
