HOR 41" Zonda twin cat build

[sampit]

Well I bit the bullet a bought myself a HOR RTR hull less the motors and less the escs, arrived safley in a 3 days
the price was good and a cheeper option hopfully be running a little quicker than a full build.
I indend to use two Fightercat 300A 2/6s risky I know but no other choise as Fightercat keeps ignoring my emails redarding the reliability problems some folks have had with these escs, so hopfully be running on 8000Mah 35c/70c
2x4000 packs hard wired in parallle. or maybe better on 3s2p and smaller props for a little less RMP

Motors are the Trackstar 6 pole 4069 2650kv custom macined to fit 40mm x 40mm Leopard water jackets
the Props that came with the hull are 42mm CR CNC

Apart from the mototor mounts being set a long way forward this makes it hard not to run the lipos on the tunnel floor without more work moving the mount back to run the packs in the spoonsons, as its not really being build to handle but just fast staight runs im hoping I can get awy with it at lest for the time being.

I got the escs timming set at 10 degrees not to sure if this is right ? also need help with the pw setting?(CANT REMBER WHAT ITS CALLED) without looking setting is either 8 or 16, I think most motors run on the 8 but im not sure if I reed that these motors need to be set at the 16 setting?

Any help or a Mentor would be a great help, do you think the setup is a bit hot for a 4s setup, any idea of speed? I am sue these motor were ratted at 2560kv when I bought the first one.
more to follow with a few pictures at the setup.

8k PWM
3 deg. Timing.

Thanks Keith,
Do you think the setup will work, I followed your lead when you bought these motors last year, it worries me a bit because i think you sold them

[twissted]

I did the same. 3 days Wow That was fast. I hope I get mine soon. I went with the kevlar Zonda. Here is what I have waiting to run my boat.
82037 This is a pair of 200 esc's and a set of cap banks and 1 BEC @ 7amp that will run the titanium HV servo.

82038 This lower picture shows a KV meter to tune the motors. It is the orange box.

Haha Sam you can't stop buying boats (just like me!) have you finished the cheetah and apparition yet?

Did you get stung for import tax? That's one of the things putti me off buying a hull from abroad, post some pics up so we can see, I love my twin apparition and a 41" version should be awesome!

[sampit]

I got the Kevlar lined hull a little disappointed I thought I was getting a full carbon hull with a Kevlar lnlay
Turns out the Zonda is a figberglass hull with a carbon/Kevlar inlay and painted primer grey
Still for what it cost it's a nice boat
Not sure about the square drive lines yet but they should be ok no more losing cables and props
That on it own is bonus I lost 2 cables and props last week,starts getting expensive

[sampit]

Matt nothing extra this time £285 to the door so nothing just a knock at the door with a 41" box bonus!
Luck on my side again
I give you a ring ,if your around in a bit

[twissted]

So the pictures showing the side walls with the kevlar is part of the inlay?
Could you show a picture of this inlay?

[twissted]

I ran a search on google 41" zonda pictures and came up with some videos that showed a zonda with prop change and running 6s clocked with a gun going 110 klm.

[twissted]

I would think that having the batteries in the center would be a better handling boat. This is my first catamaran and so this is some of the things I will learn. But it would seam to me that unsrung weight would aply to boat as well as cars.

[sampit]

All the lower part of the hull is lined including the side walls
It would have lined before it was joined so it's a proper job no need to panic you will like it
No realy an inlay sorry.

I just ordered the same boat last friday and will be facing some of the same challanges. Is it ok if I ride along on this build?

[twissted]

Do you think that there will be cooling issues with the rudder pickup? I was thinking of drilling hole and installing a pair of pickup tubes, next to the stinger mounts.

[twissted]

Well radio signal should be good.

[sampit]

The water line goes from the rudder to a three way splitter each one feeding an esc and motor it has two outlets one in each sponsons
I'm going to change it might get another three way splitter a send it all in to one esc then the other and only use one outlet
I'm not sure if each esc would get even water flow the way it is now maybe ok for the T120 escs

[sampit]

2.4 radio works with no problems with range issues
Fm might be dodgy!
Same Kevlar hull as my Cheetah works great!

[sampit]

Had another close look at the hull it think it might be all Kevlar and no glass
There's no joining seems and the top i think is also Kevlar not 100%
Would need a second option

[twissted]

I have mirror that is pretty handy for this kind of thing.

[twissted]

So could you show the stingers?

[twissted]

So you don't like the motors that it came with?

[LOVE6S]

Sam, how much was the boat with shipping, minus motors and esc's? Did you have to call them to get it that way?

[keithbradley]

Thanks Keith,
Do you think the setup will work, I followed your lead when you bought these motors last year, it worries me a bit because i think you sold them

I still have 4 of them, just haven't gotten around to building anything with them yet. They should work well. Keep the props small and the timing low.
I did notice some problems with certain ESCs when using higher timing and somewhat high RPMs. On 4s you should be fine if you keep the timing down...it still doesn't hurt to do a bench test on any setup though.

[sampit]

Thanks, just waiting for the other motor to turn up

I Set the timing to 3 and set the PWM at 8 on both escs

I have soldered together the two black 8AWG esc leads in to a 8mm bullet
but not happy the wires are to thick to get a nice solid connection

What do You think I need to make a set of 8mm esc connectors ?
or can I buy them?
Might be ok on the battery side,hard wiring both black and both red lipo leads in to two 8 mm bullets

Because I have conected the two escs together on the FC escs do I just use a
Y lead?
and do I need to remove one of the red wire?

Twissted:

If you want to post other people's pics to a thread, you can link to the original, or if you pull the pic you should let people know where you got it.

[twissted]

Ok I'll do that. I pulled these from my photobucket files.

[keithbradley]

Ok I'll do that. I pulled these from my photobucket files.
Why do you have my pictures in your photobucket files?
That's the third boat you have posted pics of that I have built.

[JrValente]

Keith, I think its time to get a watermark..... Sucks as I hate drooling over pics with them but......

[Jason4636]

Get'em Keith

[sampit]

I just emailed Jonny at HOR nd asked for price less escs and motors
$440 delivered I think mine was!
I think that was xpress delivery around $50 more than the snail post.
3 days and no duties to pay
I got lucky as I often do. but put some extra mony aside just incase you get hit with a customs bill

[Mattwarner]

Sam sorry I missed your call the other night will call you over the weekend, that's not a bad price for the hull and setup I especially like the stingers and doesn't look like you would need to replace anything just chuck in a decent set of motors, esc's and good to go almost.

There's a few places in the uk that stock this hull (bare) so this maybe my next build unless Sam sells his cheetah!

[iamandrew]

Ive had some pretty good results with dealing from HOR racing.
Once was sent a 1/4 collet instead of a 3/16, he said he would ship me one out :)

So the boat comes with 2 peice flex drives?

[keithbradley]

Sam, I'm going to tap out on this thread. If you want, you can reach me on my forum and I'll answer whatever questions you might have. I'm not interested in sharing info with one of the posters in this thread at this point.
Sorry for the momentary derail.

:focus:

[Mecka1990]

where you get the servo holder/mount from? got the same boat (ordered, hope it comes this week) and dont find a servo holder -.-

[Mecka1990]

and you know the stock motors that comes with the boat? im searchign them already 5 days but there is no information what manufacture they are and what detailed information they got :-(
