atomic 58 inch catamaran motor question

[forescott]

My motor was running hot @ 18degrees timing. I ran it again today for 5 minutes with the timing @ 22 degrees, swapped all the stock 4mm bullets for 6.5's on the motor and 5.5's on the batts. Also raised the strut about 1/4 inch to free up the prop. Temps came in at 130 on the motor, about 105 on batts, and under 80 on the esc. top speed increased from 40mph previously to 43.7 today!! uploading some video as we speak.

Here is some not so good video with me filming by myself....

Good to hear about the temps.
Vid looks pretty good to for the first time on the tx,
The boat looks like it is riding nice to.
It will get better and easier the more you use it like a side arm gun,
Or like shooting from the hip.
Keep testing with more timing and see how it likes it,
What size prop are you using ?

Ok what is the hold up now ?

It is 02/10/2014 and still no new, Info or Pictures or Video's.

I spoke to Ken and Damen today and we were talking about going out next week or the week after. We will not let the cold keep is away.

I know may be next year we will see something.

W T F
Come on What's the facts 3.5 week and still no Data, Pictures, Or vids.

Spoke to Damen today, he said he would upload the pictures tomorrow. I knew I should have used my video camera. Ken did the video. I will call Ken tomorrow to see when he maybe uploading the video's.

Hey Rob do you need some batteries for the flash or may be a bigger mirror ?

I spoke to Damen, he is working on the pictures. I have not spoke to Ken yet. It has been crazy over here. It was my daughters birthday this week. I will be calling Ken tomorrow.
I will be checking the data tomorrow too.

I also use a GoPro using the head strap. Your head is always following your boat.

Ok hey you guys, It has been two weeks now.

So what the hell happen ?

Do you need a flash light and a mirror to look for the data, pictures, video's that Damen & Ken have ?

I went out today. It was low 60's here in south central NJ. Unlikely that we will see that again till spring. The Atomik had a glitch on the first pass. The water feed line came off going to the water jacket. The boat filled up with some water. Brought it in, fixed the line, topped off the batteries, watched Ken fly around with his Genesis.
Reset the GPS, secure everything and try it again. Off the work bench into the water the boat appeared to be on the money. I was using two 4s 6000, 25~50c Turnigy Nano Tech batteries. I know they are under in the C rating. Surprised after a 3 to 4 minute full burst straight away runs, the batteries were at 85 degrees, the motor was at 90 and the ESC was at 88 degrees.
With the GPS tuning off but recording the max speed before turning off due to low battery, I recorded a max speed of 59.3mph. I was a very smooth ride. Ken did the video and Damen did the still photos. When I receive them, I will post.
All in all, I am happy. No tweaking was done today. I just enjoyed it. I will now tweak it a little to see if I can hit the magic number that we think it can hit (70mph).
I did roll it, which landed right side up. I think after the first roll - the battery tray separated. The boat was leaning when accelerating from a stop. After moving it would level out. The problem was when I would release the throttle the boat get loose. The boat rolled two more times - always landing right side up. No other damage or problems to report.
I did use the data recorder. I will check that tomorrow.

I just picked up one of these, bare hull and wondering what would be a good motor, that would bolt into the stock motor mount? Plan on running 6s.

I was looking at this motor, seems comparable to the stock motor, or should I go with a different KV or different motor?

What speeds are you looking for with that hull ?

[birdy233]

What speeds are you looking for with that hull ?

Around 45 would be good,

Was also looking at this motor too, just unsure of what KV to get

Also, what sized flex shaft does the boat have, I haven't picked up the hull yet, just want to get what I need beforehand

Thanks for the info in advance

[forescott]

you want the 1100kv version of that turnigy out runner. Are you getting the ARR version of this hull with the stock hardware or just a bare hull. The stock flex cable is 1/4" with a 5mm prop shaft.

[birdy233]

I'm getting the ARR version. Would the fightercat motor be better than the Turnigy?

[forescott]

They are actually the same motor. You'll notice the fightercat description says t600. They just have his logo on them. Either one will work just fine.

[forescott]

Doesn't the arr version come with everything but the radio,motor, and esc?
