Flexdrive cable adjustment

[shotimes95]

How much grease do i use on the flex shaft? I know too much is not good and not enough is just as bad. Also when looking at the cable when it passes through the hull, the cable is not centered in the tube thats part of the boat. Its at the top and im not sure if thats incorrect or will ruin my hull? The boat has only been used twice and i want to make sure everything is right before i run it with the new lipos.

Does anyone have a picture with the shaft properly adjusted?

Also is it best to use timing on high or low when using the x642? I have it programmed at high right now but dont want to burn ur the electrics up. The boat is stock except for Darins tweaks on the fins.

Thanks in advance!!

Start out with low timing and check you're heat after a couple of minutes. The 642 is a popular prop choice for the fastech, and should be fine. As far as the stuffing tube goes, are you talking about the motor end or the prop shaft end?

[shotimes95]

Prop shaft end. The flexshaft wasn't even greased from the factory!

[forescott]

Can you loosen the strut and adjust it up or down a touch until the flex shaft centers where it exits the brass tube?

[forescott]

More lube is better than not enough. Kinda hard to put too much because most of the excess will come of as you slide it back into the stuffing tube. I've never had issues caused by too much lube. If you're using the right kind you shouldn't have any problems.

I adjusted the cable and centered it and it looks great! The grease I used, until the proboat grease and gun come in was TRI FLOW. Its a clear synthetic grease thats waterprrof for packed bearings, cable assemblies and gaskets. I hope it doesnt load the motor and burn it up...

mine always seems to break the solder joint loose, it only seems to happen if i have a little positive angle on the strut.

[Deserthobbies]

here is where it spins loose.

[shotimes95]

Great advice! I saved myself some trouble by noticing it up front lol This forum is soo good!

[shotimes95]

Thats on the motor side rite?

[Deserthobbies]

no its on the other end , the prop shaft goes into that coupling in the photo. ill upgrade it if OSE has a new strut and propshaft that will work. i have never spun it loose from the motor end in the collet.

[shotimes95]

ok i got ya... had to look at the boat. its still new, only had it for a month or so. When i pulled my cable out it was completely dry and after i lubed it, it was so much quieter. go figure

[shotimes95]

do you need a pair of 4200mah proboat batteries only used twice? I bought the boat on my honeymoon and they didnt have the programmer card so i bought them instead until the card came in.

[Deserthobbies]

guess ill just clean it up and silver solder it with some 15 percent silver solder, drill a small hole all the way through it and drive a small pin in it. sure would like to put a 3/16 strut and driveline on it and i can throw them little brass prop adapters away. LOL

Steve or anyone else that reads this can you steer me straight on a upgrade. ?

how much, im sure my friend will take them for his, I run lipos in mine thanks.

[shotimes95]

Ive soldered things like that before and using the hole drilled into either side will allow the solder to flow into the joint as long as the temp gets hot enough. In my opinion a pin may not be needed but theres alot of guys on here that know more than i do lol The engineer is coming out

65 shipped there on the swap shop but ppl want em for 40 bucks for the pair shipped and shipping is 15 alone! I really want to trade them for a x642 s/b and some $ but no one wants to deal... 65 isnt firm

[shotimes95]

im willing to deal and help someone out if they can do the same for me...

I may have an extra X642 prop, i balance my own , first one took me 6 hrs , then i bought a Stainless Steel and have about 8 hrs in it, its very time consuming to do it correctly sure glad i'm retired. lol

[shotimes95]

that helps! If he wants em give me a call. ill give u my number, i dont have paypal but will do whatever is needed to help a fellow rc modeler out! Ive been told a 642 will make a big difference. Im running a stock prop with darins tweeks and 2 7.4v lipos

[shotimes95]

wow ur a retired EE!! Im sure you could get a electric boat to scream! Im a body engineer for Ford

I also ran Darins tweeks and they made a big difference , if you havent seen it i made my own tweeks but it does best with a 440/3 three bladed prop, im running Track Power 5000mah 40C lipos, got 42.6 mph today on the glassy smooth pond

[shotimes95]

40c is more than im running... i got 2 7.4v 4000mah 20c lipos. Just hope they make the boat run good!

[shotimes95]

One heck of a job on ur boat. Retirement really is paying off for you LOL Ive raced rc cars and trucks for the past 14 years and boats are new to me. But a forum and trial and error is paying off

[Deserthobbies]

the boat actually calls for over 25C batteries, watch your temps.

[shotimes95]

i didnt know that. proboat told me that the 20c were ok. they run losi 20c in there proboat video on horizon hobby. mine have a burst rate of 30c.. now u got me worried

[shotimes95]

and i have the timing on high and havent ran it yet

This is my first boat too, they are a blast , my Helis stress me out too much. I am considering putting floats on my Bell 47 for a boat recovery system. lol . yep too much time, ill sure be glad when Darins Stiletto gets here. i'm running out of stuff to do.

[shotimes95]

ill go pick up some 40c packs tomorrow...

[shotimes95]

would 5000 mah 50c be overkill?
