The ones someone posted earlier might be an option,cross between a z drive and direct drive.They also do some scale looking struts but not sure if they have em in gas size.

Right on Mart .......... I have had a set in my hands and I would not use them on a twin ... good quality just look fragile in some areas.

These from Werner are quite a bit better

Neither the RCMK or WD are sold in USA that I have seen .. WD link takes u to their site - prices are cheaper than shown as they include Euro VAT tax - we (US and Canada) do not pay VAT tax so around 20% less.

Werner is good guy to deal with and Hendrix (on here) works with Werner for any English translation issues.  Both are great guys.  The WD is proven in some BIG boats

WD (Werner) stuff can be ordered direct and takes about 10 days to get here

Oh
 The ONLY way I know of guys getting those drives from RCMK are from Mr. Park direct - I do not or have not seen them on any site.  Pair I seen were when I was overseas this year.

compared to the build the little hassle of getting werner to get them here will be easy, those drives look great and should be worth the wait.we just ordered the gear box i will post as soon as i get them and you will have an idea of time fram, 10 days sounds pretty good,

wantariva

ok so that settles it...wd drives it is...they're cheaper than RCMK too by the looks of it I like his radio box too...

IMHO you are headed for big trouble with any steerable drive. S520's under best conditions stress 1/4" driveline parts well past their limits. The only way to keep the cable in one piece is to keep the cable under control. Running a 1/4" cable in a 5/16 tube will NOT work. The cable will whip around and blow out everything between the engine and prop. Any drive that has unsupported area of the cable and bends the cable to steer will have a very short life behind a 520. Standard stinger drives with a seperat rudder are the only way to go.

Keep in mind that all of the available drive hardware was designed with a 260 Zenoah in mind. S520's at ten hp. more than double the power of a 260, a modded S600..more than quadruple the power.

WD drives were NOT designed for just a single Zen - even boat in video is no Zen ...

wantariva

do the wd drives bend the cable to steer or do they have a universal joint at the transom like the rcmk pieces

martno1fan

Good point mate,most eoropean guys like there Mathes and big power so might be an idea to get Hendriks view on this,im wondering why he hasnt allready found this thread and replied.

we did go thru a lot of cables in the beginning,the 520 will exploit all weaknesses in a drive, we have even sheared the dogs off of stainless steal drive dogs, thats pretty bad when the drive dog is the weak link and still breaks,

wantariva

do the wd drives have universal joints at the transom?

RCGasBoat

this mean machine is going to be a disaster in the making.....good luck!

wantariva

why do you say that

expresscraft

am i missing something in the video?its almost the same build and the boat looks to be running pretty good. i cant remember if he had steerable drives,its on jims rc boat dock somewhere

blizard05

What 's up with that???

expresscraft

just looked they are not steerable drives, they are 2 fixed drives with one rudder in the center, but his post indicate that he is doing fine with it, last post they burned up a thrust washer, big deal its a nice boat, im sure glad there are some willing to take risk, thats why we have some of the great things we take for granted,so your build will come down to how good is your universal joint, or a hopped up cvd type drive,i dont know that my plan would include a cable. but i would not call it a day either.

Expresscraft said this build is on JBD

wantariva

what is JBD? I keep hearing about it but I have never been on that site before. Im starting to gather funds for either this boat build or eventually a built shortblock for my Mustang....I dunno which one I want more right now lol I like the simplicity of the stinger type drivesbut they just look so out of place IMHO. I was thinking about the shaft durability too...what about a 1/4" piece of steel square stock? Provided I set it up with no arc in the shaft of course...

As far a drives for a home built, W/ two doubles small dia pipe would fair better in a shaft housing IMHO

the cables work fine in a fixed drive line, the inline twin, twin build WOW..is in the 60" boat section under project builds and it was a couple of pages back,its a great thread,
