Delta 29" copy build -help needed!

[Boogie]

Ah, I know what you mean, I'm trying to keep my budget halfway under control for the moment. I found out real quick that I'm not a fan of the BJ26 or the SV27 hulls, but both seem to have decent electronics. I think I'll end up getting that 29" hull and stick my BJ26 electronics in it, get some speedmaster hardware and a new prop, call it built and quit fooling with these rtr hulls, lol.

Few more pics, maybe these will help you guys to tell me where should the strut and rudder be mounted.

If you have worked with this hull ,great, if not -but you do got an idea what to do, give me some info here!

I get that the strut should be in the center , but what is the correct height?
I did read somewhere that 1/8" from the lowest part of the hull is good place to drill a hole to... -anything to do wrong here...

And the rudder, left or right? -usually on right side, is this because the prop turns counter clockwise?

How low should it be? -lower then prop, but how much?


Is there anything I can do b4 I have the motor and scuff tube?


Oh, and I ordered this too, the mount I ordered b4 looks a bit flimsy. http://www.offshoreelectrics.com/pro...rod=tfl-509b14 -was this good choice, or do I e-mail Steven and change it?

[M.M.]

That mount should be fine


I actually have the 380 mount in a 25" DF copy, but i changed to a fiegao 540 8xl. So i just widened the holes a little bit, and it seems to be fine.

Are those the stock SV parts?

[FastVee]

Are those the stock SV parts?

Yep. I did some de-anodicing and polishing to them thought. -and changed the 3mm stainless bolts to 4mm acid proof ones.

[Rumdog]

Don't get discouraged man! that boat will still be a blast with the SV parts. You can always change the motor/esc later if you want. Rudder/ right side deep in the water= good turning. These boats are designed to turn better to the right. If you wanna make left turns, you'll def. need a port side turn fin. Also, if you just upgrade the esc, You can run 5s on that motor and she'll really rip!

[ksm2001]

I and a couple friends have this hull running 540 8xl (or equivalents) on 4s lipos and the one thing I know is that it likes a rearward CG so plan your equipment placement accordingly.

Steve

I run the same hull as you have and with Steve on the CG , I have mine set to 28% at 30% it runs to wet on smooth water, but you might want to set it back a bit more if you run the SV motor.
I'm running a 8xl on 4s also with a 200amp Himodel esc and a m445 and it spikes at 139 amps at 57mph.

here is my build thread. http://forums.offshoreelectrics.com/...ead.php?t=6414

and a video http://www.youtube.com/watch?v=7G55cKQOHoU

I think you'll really like this boat, it halls azz.

1/8" is good for the strut height. I removed the trim tabs, not needed IMO.

[tylerm]

This is a nice boat, i have one in green but looking back now i would have preferred blue or orange.
For the strut height with the SV strut, try 3/16 - 1/4" up from the bottom of the hull, my one always liked the strut up high. COG like Ken said 28% onwards, you may need to run up to 34% on real rough water.

Dinner now, more tips later.

[FastVee]

Ken. your boat is one of the reasons that made me order mine! -so I have read your thread. -And watched your vids. Sadly there is only a few df 29 on yt

I am planning to install strut and rudder, nothing more at first. If needed, will put turn fins and trims, but want to try w/o them first.

And that 1/8" ,is that at the top of the hole or center? (and still thinking is that high enough... I will use X642, and p220 on this)


And since this is my first rc hull that has gelcoat and proper f/g work(sv did not) I did not belive how heavy this is at first. It really feels much stronger and stiffer compared to sv hull.

It is a bit sticky inside though, like there was not enough of hardener used on resin, any thoughts? -it was delivered inside an airtight plastic wrap so it maybe havn´t dried completely b4 shipping. Maybe I´ll wait a bit more , and add some epoxy to help it dry if it wont on it´s own.

[Boogie]

It may need to cure a bit longer, just leave the hatch open for a few nights, which is probably what you already do anyways. They may not have used enough hardener or they may have just got done with the hull right before you shipped it and it hasn't cured fully because it was sealed up in plastic, who knows.

KSM2001, I was actually watching your vids last night on youtube, your boat definitely hauls ass! I'm getting ready to read through your build thread to steal some ideas for mine, you guys are definitely making me want that 29" hull.

Do you know how the 8XL compares to the BJ26 motor? I'm assuming (at least with that prop) it pulls more than the BJ26 motor since the BJ esc is only rated to 45amps.

[ksm2001]

The 1/8" is from the bottom of the transom to the bottom of the OD of the strut tube.

MY hull was a also sticky inside when I first received it, but like Boogie mentioned leave it open for a few days to cure. Try running it without trim tabs and if you run turnfins set them up higher or tilt them back to stop the chine walking on this hull.

I moved the motor back further to get the 28% since the last pics on my thread. I'll try posting some pics tonight on my update.

As for the BJ motor I'm not sure but I know that the 8xl will fry the 45amp esc with a x642.

Ken

[FastVee]

Ken. I thought that any xl can would fry the sv esc, so I did the slow, but hopefully smart choice and ordered the stock sv can.

The hull is HEAVY ,so I´m still unsure can I use the x642/220 on this, but I do have external bec so maybe.

Are you happy with that 1/8" height, or thinking of lowering it?

And looking forward to see your new motor location pics.

[Flying Scotsman]

I would suggest you start off with an X440 run it for 60 seconds and check temperatures. Interesting that your DF 29 copy is heavy, that is actually with liPo batteries and brushless motors power an advantage. What is the hull dry weight? I would never run more than 4S on your proposed setup.

I dont have any accurate scale here, but it weights a bit more then .5 litre energy drink can ,so about 600-800g -way more then SV.

I have SV´s stock 3-blade, Graupner K45, X642 and P220 . So I should start with sv prop?

How can more weight be an advantage ? -more stable maybe, but wont that draw more amps?
