Talking WD200, they have two options of steerable drives: the 'stinger/arneson' version and the 'Lenkstrut' version.
Looking at the drives and their sizes, I am a bit afraid that the propellers would be too far from the transom of my 1500mm Waverider Apache. What do you think?

I will also drop an email to Mr. Park, to see at what stage they are with their drives (that look beautiful). But, after more than a month waiting for the Z-drives, I am a bit over waiting...
Looking at pictures from Germany of the large arnesons on the transom of an 84" apache the scale looks good - I do see your concern if the boat is under 1500mm as how the scale will look. I have not seen them fitted on a smaller apache - could be interesting!! http://imageevent.com/justaddwata/mo...ics/bigapaches

I share your feeling with regard to waiting - I have waited too long for too many things in this hobby (one time over 6 months for some items from MHZ). Waiting is no fun at all.

I just measured her: from transom to bow she is exactly 1430mm

How would such big drives impact on the boat's performance?

Here are a couple of pics: I rebuilt a hatch to look like the 2010 Cigarette Racing AMG boat. She will be professionally painted as so too.

Thank you Mart,

it took a LOT of work to make the back part from scratch! In the end I think it will be a decent replica...

i have the MHZ drive on a 57 " Apache and it handles realy well the prop face is about 3 3/4" to the back of the transom i think as long as you get the CG right it will be a verry fast and well handling boat your hatch looks great to

Hello mate, thank you for the hatch!

Unfortunnately the MHZ Z-drives I ordered are no longer available, therefore I am considering the steerable drives from WD200.
The Arneson style is over 180mm from transom to props.
3 3/4 measure you are talking about translates ina bit less than 100mm, that is almost half the leght of this Arneson option.

The other drive, here: http://www.wd200-modellbau.de/?Antri...ives:Lenkstrut
This drive has a total lengh of 130mm, and should be about 80-90mm at the prop.

It looks to me as this second option is more appropriate to the size of my Apache, although the Arneson style looks better...

This is how the lenkstrut drives looks on a 1260mm Titus from MHZ.
I like the scale looks of it, although (as JAW pointed out) I don't really like the idea of those drive calbes flexing under all my power...

Picture courtesy of WD200 site, this is a boat he built:

Cables should be fine with the power of a single 520. If you had one 520 for each cable you might start seeing failures though looks like they are running them with inline zens to each already.

If you went with that setup id run a teflon liner all the way into the drive or your cables will be subject to all that salt water [:'(],they do look good though .

Good to know about the cables JAW.
Yes, also I would run the plastic all the way back: both for the salt and for the boat's hydrodrag!

I just received an answer from RCMK, regarding their new unit:

Dear Adriano,
Thanks for your mail
We will ready to supply the "Trimax Surface Drive unit" to our all customers at the end of November.
Thank you.

It could be worth the wait...

Cheers Mart,

will come together as soon as I get the drives!

Thinking of the RCMK option, I don't really think there is much that can go wrong apart from the joint... If they proposed the part at the beginning of the year, and start sales only now, I should think they have been thru a bit of R&D testing...

Still have not made my mind up on the exhausts, did you receive yours from HOR racing?

Yes, but I wouldn't want to save some money upfront to then find a bulky part that brakes down on me.
If the quality is poor, it no longer is savings, but a lot more expense and hassle!
Anyone running these Korean gas pipes and accessories?

Just got the answer from Mr. Werner at WD200, he stated that the Arneson-type steerables are infact too long for my hull.
This takes the decision down to his Lenkstrut (as picture above), or the new parts from RCMK

The quallity is fine m8 i know a few guys running these pipes in fact about 5 of them in my hulls that i know of.Fact is most of the dealers over here and the States are selling this stuff,they just dont let on where its made and then bump up the price by 100% .At the end of the day its your choice and your money ,maybe see what MHZ have?.

Just a quick update: I have ordered the RCMK drives, and should receive them at the end of this month. Still don't know about pricing.

Mart - have also ordered the exhausts and some other parts from Frank. He treated me good, thank you ;-)

Cheers,
AJ

Yes, I am taking many pictures!
I think these drives will be very well performing: by the way, they measure 12,5cm from transom to drive dog. This is appropriate for your hull.

I hope they will also be reliable: to be sure, I already ordered a replacement drive line/joint for each drive.

Yes, I am also very curious to see how these parts are. From the pics, they look great!

- RcGuy - Measurement-wise they should fit perfectly on your Apache 65!

RCMK told me they are now building the hydraulic dummies: the drives should be ready maximum within November!

Am here trying to find a new/different way to absorb more of the vibrations going from engine to hull: those are bad vibes for handling!
