MHZ Mystic M 1140mm build

Imagine the howl of twins on this lake !!
It's alright mate, I'll give you a head start

Kent is camera shy "dont show me on the video" and coincidentally FYI iPhone video is garbage.. there's not much worth watching between the edits where I removed the man

I'm far from shy! And don't need a head start either. I'll lay low about the RRP sorry top speed you did this afternoon.... haha

[nata2run]

You'll probably like the extra pitch Kent.That is my next choice.Hopefully next weekend with Andy from AC Boats.BTW That lake looks awesome.Is that the new house over there?

Hehe not my house, but I live just around the corner. I have just ordered some 1816/3 from Steve. Should get some ok speed if all goes well.

i just have in my hands a pair of octuras 450/3 r+l reduced to 46mm.those will be my next props testing, first with 5S and later with 6S.i will inform you about speed and ampers data by my eagle tree.i have on way to Athens a pair of propshop 4518/3 l+r for hardcore runnings.....hehehe...!!!!

[nata2run]

Sounds good dino, keep us informed are you running Leo's or Lehners at the moment?

[DINO7]

hi nata.leos are in.... my mystic sit on the shelf 3 months now.i was tuning, playing with my intruder twin cat....but now is mystic time.when we have better weather in Athens-its raining now with 3 celcius-i will do some test with all props and i will post here....
lehners are going in a new 1 meter cat that im ordering tomorow....hehehe more drug-building twin cats for me....

[nata2run]

Dino, any reason why you pulled the lehners out of the mystic? Are you getting better performance with the Leo's?

talking lehners.. what size/Kv are yours ?

[nata2run]

Hehe mine? 2280/11 so around 680kv ish loaded. Would be good on 12s with big prop

[DINO7]

i have 1950/5 2500kv.they run hot in my mystic so updated to bigger leopards..lmt motors are the best for saw ,they need full open gas for not being hot.i wanted something bigger motors for every day runnings..

[nata2run]

Could it be with the your Lehners or any other motor, that you are spinning bigger props (for the motors) but once the boat is on a plane and the props are half way out of the water, the resistance eases?? and motors spins more efficient? pulling less amps. I could not imagine that a motor was just designed to run flat out. The load is what pulls current, true? just because a motor is rated 5000w or 200A dont mean it will pull it. but even if its rated 5000w it can pull 8000w just not for long.

Hi Nata,

I thought it is better to continue in this thread. So as for your setup with 1717's with 1580kv on 6S I think flat out it should reach ~105km/h with X447's. As you also mentioned a runtime of 11min (may be a bit too optimistic) power consumption is really low and therefore enough potential left for using bigger props. The X450/3 should definitely work but I think they won't be enough for 130km/h - just give them a try.

Therefore I'd try props with higher pitch than the Octuras like the ABC 1816/3 you already seem to have. They might be a bit tricky for finding the right trimming, a quite good option are the PropShop 4518/3 (same as Dino mentioned).

Best regards,
Manuel

The max speed with the 447 was 96.7 woul like to get say 130 would I get that with any props or do I need to jump to 8s? Where can I Get the propshop props? And why woud it be tricky with the 1816's?

Hi Kent
The Prop shop UK address is http://www.prop-shop.co.uk/

With alum 445 props from your friend Joe I got max speed 108.50 klm on 6s

[nata2run]

Hmm but you got 2200kv motor right? So you are spinning the props much faster. It would be like me running on 7s have you ordered the propshop? Would love to see what they do.

[nata2run]

Just ordered the 4518/3 SS L & R not cheap! But should look good polished hehe. Starting to have a collection of props LOL this better be good
Thanks Nick 4 the tip
