Hello guys!
I whant to build a new boat and because I had good experience whit my last vhull whit hardware offset I whant to try on a catamaran hull.
Any advice?
I whant to use the strut rudder sistem from MHZ https://www.mhz-powerboats.com/Antriebe/Struts/ but the propeller lock to close to rudder blade,it's someone here that use this sistem and giveme some feedback?
This it whill be a SAW one
i use the 4.76 strudder from mhz on the mystic 84 and works great (i run this hull with a TP 4060 1380kv on 8s)the only thing is there is limited space from drive dog and rudder blade with octura or prather and cnc prop it's no problem but with abc props you need to adjust the rudder blade (tfl rudder blades work aswel)but the boat runs great and 130km/h on a small lake is for me ok
Hello. Thank you for your reply, it's amazing a baby mistyc with only one engine and a rather large one, I want to build a DF Pathfinder 28 inches, but I want to offset the drive line between 2 and 4 mm to the right as you look at the rear hull. It would be interesting to see some pictures of your mystic and I have built two baby mystics but twins, I will use a TP 4074 engine on 8s and the maximum propeller will be ABC 18 maybe I will try 19 but I think it is too much
greetings, with some news and a delay in the project the boat was finished and raced a few times
the boat came quite thin and had to be reinforced but on the outside everything is very well made and very flat underneath that's a good thing
the transom received 3 layers of 200g/m² carbon and the rest of the boat 2 but from several stages and patches, I tried to make everything as dry as possible
the cover received two layers of 160g/m² glass for gps signal
the cover received 4 m4 screws with countersunk heads for better safety against flights

so after hardening everything is stiffer now
on the outside I didn't need to do anything as I said the boat sits very flat and all the steps touch equally
after a little placement test on the inside the assembly of the parts started
I decided to shift the running gear 3mm to the right I know that on V boats this helps
I mounted the rudder as close as possible so that the biggest propeller I could use wouldn't interfere with the rudder blade when turning
I mounted the strut starting from the neutral position trying to be perfectly perpendicular as well as the rudder

after correctly aligning the motor as far forward as possible as the cover allows, I rolled a piece of flexshaft into the coupling to find the exact holes and angle for the brass tube
for easier bending, the tube was heated with a gas lamp and cooled several times to become more malleable, then I inserted the teflon tube and the flexible shaft and bent it slightly to the desired angle
the motor support bonding and the tube sealing were done with resin and glass flakes, I did not have carbon flakes for a better look

after mounting the rudder followed the hole for the drive rod and securing the servo support, from a carbon battery support I made the esc support and a small receiver support followed the water circuit with the exit in front of the boat and up not on the side for a better view, a single circuit because I will use a water pump

the boat weighs 3.6kg with a 2x3s6000mah setup
the boat was filled with pool noodles and the batteries will be secured with them as well
for the first run the boat was balanced for a 2x2s 5000mah setup for the 4s which reduced the weight significantly

maiden run and the only run,it was a good one,setup 2x2s5000mah cnhl 70C for 4s,TP4050/2350kv ZTW Seal 200A esc and ABC 1916-17-45
