Got a couple runs in today with a little video. Still poor quality...what format do you all save your youtube videos in? This is mpeg 4 but I can save about any format.

Anyway...this is the China cat 32" HOR with 8XL 30C lipos, Etti 125 amp ESC and 062 wiredrive with one of my bearing struts. Faster with the X442 but gets warmer. This run is with a M440.

Looks great, fun speed also.

going to be setting up a 32" cat in the future, wondering what your amperage you are pulling in that setup, mAhr and/or run time.

Nicely done man, nicely done:bowdown:

Getting ready to reload the lipos so I will see. They got warm but that was all. Motor was pretty warm. Prop was pulling a bit so need to put a better edge on it.

Etti 125 amp ESC was also warm but no issues. Need to take my pocket temp unit with me and GPS on Friday. It is a big lake and it traveled it pretty fast. No issues with the tactic 2.4...man I love no antennas!

Guessing I would say it was pulling 80 amps or a bit more.

Jeff ,

The cat looks real good on the water mate.
What sort of speeds is she doing.
Needs some paint or decals.

I've got a octura y537/3 prop sharpened and balanced.
Its bran new , i bought it for 1 of my sv27 ran it once but the sv27 did not like it.
It yours if you want it. $30
Let me know

With that prop...M440 I think it is only running about 42. I still need some strut tweaking and might get her up there but with only a 125 amp ESC I have to be careful. Once I get a bigger ESC I can prop it up a bit.

I heard a 937/3 is good to with fecalc but the ESC will not handle it.

Looks good Jeff!

As for the 937/3, are you talking about the "V" series? If so its probably not going to like it at all. Way too much lift. I ran one on mine and it was horrible.

Your HOTR catamaran looks good, may be something wrong with the propeller or strut adjustment, try Octura X442 and X642 :thumbup1:

It is running a m440 and I did run the 442 and certainly faster and lifted more. I just need a little strut adjustment.

Nothing too special except it is the first boat I have finished for some time.

I will get it tweaked and it should be okay. Need some paint soon.

I only have the strut 1/4" from the sponson bottoms. Not sure I like the rudder behind the prop....I thiink it torques the rudder when wide open.

i have mentioned in other threads about the inline rudder needing a good servo and a thick servo rod so it has no play, but the hull still gets squirrely under hard exceleration, you can see it in your video coming out of corners and accelerating hard.
think the best i got for short speed runs was a x447/3 cut down to around 43mm and detounged, bit of a wild ride but dam fast and fun :buttrock:
