Had to see it again, it is a very nice boat , hope for more videos , hitting the 200 kmt ...
Sounds sweet running and super nice boat👍
Looks very cool guys! Look forward to follow along the project.
What you think is a small amount of rudder movement is a TON of slop for a 100kmph+ boat. You have to fix that. My suggestion is to move the rudder back further with an extended mount then go back to pull-pull directly on the centre-line of the pivot (servo AND rudder) vs all the offset bracket compromises you're making. If that's not possible then go to a push-pull. On an aircraft that is a slow flying scale plane a small amount of control surface slop is masked, however the same slop on a 150kmph EDF will rip the surface off. You have the same issue. With the amount of slop you have the servo is taking a beating at high speed. My 0.02c
Sick boat bro. New sub here
Man that rudder movement will make the boat dance at top speed and flip😂Nice boat but,rudder play big issue
Rudder is fixed. Watch the latest video to see and yes I agree.
I had the same issues with the push pull system. I decided to use push Rods and it worked.
I’ve changed the connection points again and it seems to be sorted.
you should try to put some pivot points in wire tubing too, making the wire rotates freely even you servo arm are bit bigger. then try to run your prop in inside rotation i think prop with outside rotation only works if it has 1 rudder in every prop
i had the same thing happen to me in full size boat hit the wake from another boat on a angle. i noticed in your footage a wave from your run before
It looked to me like the boat took a slight hop from the passing wake and only one sponson caught the water forcing it to spin against the side of the hull.
Amizing you have for sale?
the motors look like gattling guns with all the wires
To correct the rudder problem maybe cross the cables ???👍👍👍
look at the other video's to see what we did, but we did think of that
Explain to the the geico proboat 170 kmh Stok mode owners l how much did you spend for this boat. You make a real speed .
I am going for 150 kph , but my setup Mystic 84cm is the same price as 1 MGM controller.
@@dangullik1 easier to get a smaller boat to those speeds than a big boat and cheaper. I’m just a crazy fool who likes to do it the hard way😄 the aim is actually 200kph
@@radiocontrolledevents Not a fool...a fool would build "nothing ..just a big boy like me🙃
what size esc n motor u use sir??
LMT 3080 motor 860kv, MGM esc400 amp pro edition
Luar biasa.itu motornya berapa rpm?....
rpm about 35000
New update on the boat coming soon!
You spun out because you hit the chop water that you made on the pervise pass. I csll them waterdevils little swirls in the water.
What if you spring load your rudder system
Thanks for the suggestion but it won't work on a boat of this weight size and speed. to many forces going on.
Bonjour pas mal mais là vous n'avez pas pris les 123 km/h donc je reste sur ma faim 🙄
What’s happening is the rudder slack and bad geometry causes the servo to quickly hunt for center making a wobble or better known as flutter . This is a common problem for us flying large scale planes with large surfaces that apply pressure to the servo forcing it out of its center point . One easy fix is to tighten the surface so it will not have any free play . Make the rudder stiff at its pivot point I know this goes against what rc believe but it will work. Best of luck.
I fly big scale RC as well so I agree with the comments. The boat is undergoing some mods since the crash and a lot of this has been sorted.
Must have caught an undertoe u got lucky at that speed that demolishes rudders like nothing
Nice, the inside of your boat looks expensive.
Maybe you hit a big fish?
I see your running prop rotation out? That can cause walking issues. Looks like the front end hooked with the forward weight transfer, getting out of the throttle with some left steering input, and the right prop had the grip. At our weekly club races, majority of boats run props in. Greetings from SoCal 😎
Awesome feedback. I agree with the your info. We are going to try changing the rotation and did have the boat set that way initially in build stage. 200 km/h here we come!
