New X2 Up Trim

[X2guy]

OK...Here it is.
I've worked for weeks perfecting this. Unwilling to pay the high price that the Maekawa up trim costs. I've designed up my own. I've machined up the prototype and the CNC shop is in progress.
It took me a little while to perfect but now I've finally got it.
The pictures show it installed on my X2. From the neutral position I get full up trim to the point where the nozzle almost touches the hull. This is even with the back chopped 1.75" and the pump set back 2". I could even get a little more if I wanted with a little more hull hacking.
I'm still sourcing a good cable and lever combo for it. Any BMX Left side brake lever will do the trick.
I'm doing a limited production run and am initially giving the option of purchasing the trim unit only without the lever or cable. I figure some some of you might want to find a lever of your own.
The trim units will be ready in a week and about 2 with a lever and cable setup however it will be about $50 more.
The trim lever alone is $250 made from billet 6061-T6 aluminum and stainless hardware. The production unit will look much better than the prototype and not have the gash in the base where the prototype jumped out of the chuck.
Contact me with any questions. You can email me at larmourx2@hotmail.com or PM me. If you want to ensure you get one you can send payment plus $17 shipping to the same email address via paypal or contact me for my address to send a money order.

One more.....

Damn... that trim has some throw on it. :cool2:

Do you know how many degrees you're actually able to obtain with this setup?

[X2guy]

I'll throw an angle meter on it tonight and measure it. Basically you'll be able to get as much trim as your X2 will allow. Like I said above my pump is set back 2 inches and another 1.75 is cut off the back of my hull. I even had to relieve some interference inside the nozzle so it would go that high. I wanted this setup to work with both stock and modified hulls. The more your hull is chopped the more trim you'll get.

Nice!

[SuperJETT]

Very very nice, and simple so it will last.

[tom21]

oooh pretty, making that my new Precious!!! my precciiiiiiiooooouuuuuus.

hope you sell a ton of em. :bananapowerslide:

[dbrutherford]

I will send you some money tonight. I want one!

[X2guy]

Just got back from the machine shop. It's good to go. I should have the finished product in a week. I'm also thinking about doing some up with black anodizing. I thought that would make it a little more corrosion resistant when in the salt. That and it looks cool as well. If anyone wants black anodizing add $15.
Also forgot to add that if paying by paypal please add 3%. Paypal is hosing me for the fees and it's starting to add up. I have no problem with money orders. Just let me know when you mail them out and I'll put one on hold for you.

[dbrutherford]

What's the word on the streets about these Doug? :)

[ADDict]

The word is good my friends. I picked up the black anodized one that was one in the Chickenbone raffle, very nice. Just like he said, you get as much as your ski will allow. I clearenced and modded more on my hull and trim rod to get as much as I can possibly get. So much easier to pull and hold than my stock modded piece. Thanks X2Guy!

[dbrutherford]

I got one too. I will fill you guys in once I try it out.

[shawn_NJ]

I have snapped 2 steering nozzles in half with the trim. I might have mine set a bit too aggressive....lol Becareful with how much uptrim you set it for.

if your nozzel is hitting the hull you may break it

[shawn_NJ]

Not hitting the hull. The nozzle broke where the allen head pivot is for the trim. The threaded insert pulled out of the plastic.....violently.

[madscientist]

ok, i see now we may have to find a fix for that

[ADDict]

So far I haven't busted mine, and I have as much up trim as possible with this setup. Atleast I think I do. I'm going to go pound on it some more today, and hopefully won't have any breakage. Someone should make an aluminum trim nozzle. Or some type of small reinforcement for the stocker.

Any interest in a co2 version, I plan to work on this over the winter that will go inside the hull. http://www.clippard.com/cylinders/Default.asp

[X2guy]

What I found is that you have to be careful that you set the up trim position so that it clears the hull when steering from side to side. When the steering is straight you will get a little more trim than when turned to one side. If the nozzle hits the hull while steering it can put a lot of extra stress on the nozzle pivot.

We used a bunch of air cylinders at my last job. I showed another engineer there the Ski Clinic system and he said he could make one easily. I was going to estimate the force needed to move the nozzle under full load. I planned on using a small air tank somewhere inside the hull. That way you just pressurize it with a pump or air compressor before each ride. AAll you need is an air cylinder, relay, switch, air tank, hoses, and some brackets. I was all gun ho on doing this until I transfered jobs. It all but slipped my mind until Griffnasty posted in the old thread. Makes me wish I saved the video. All in all it couldn't be that hard. I should look back into it....

[X2guy]

Dave...Slap together a few vectors to figure out the force. I believe a stock 650 has about 600 lbs of thrust and some of our modded skis about 30-40% more. I think you will find it's pretty high.
My lever ratio is almost 1-1 and with the hand lever there is a little additional leverage and I can not even pull mine in at anything over 1/8 throttle.
It would be interesting to know.

[dbrutherford]

Yeah that is all I was going to do. Just take the Cosine of the nozzle trim angle and multiple it by the force. Max thrust would be with an angle of 0 degrees. I think if you played with the angle from 0 to 45 degrees you could get a min and max range of thrust. I was just going to use 45 degrees and then multiply the force by 1.5 for a safety factor. You don't want to spec out a cylinder and it not to be powerful enough to throw the nozzle up! I think I looked at a cylinder with a 4 inch stroke, double action, and a spring return.

All in all, it isn't that complicated. But I was lazy and didn't feel like calculating anything. Key is how much volume of air do you need, and at what pressure. No since and building a system and you only get two times using the nozzle. I liek air over CO2 because it will be cheaper but I imagine the CO2 has higher pressures since it is a liquid in the tank, Who knows. Someone else make one, I will jsut use your system Doug until you make one :)

[X2guy]

Without doing any calculations I have a feeling at the very least the rods on the end of the cable will bend if activated at full thrust. I've bent mine last year with my modified stock setup. I think I'll let someone else try as well.

[crab]

Problem here is the push, my feeling is it needs to pull the cable to work right.The throw need only be 1.5 inches.

[madscientist]

pushing the cable seems to be the awkward point right now.

w/ all the skillz in here this should be no problem

[RAGS]

we originally set x2addicts up to pull, but had problems finding a cable long enough. and the ride was to close so we had to focus on function at that point and just make it work with the stock setup. it will get changed in the future im sure. the hull is ready and willing ;)

[crab]

My guess is 200 pounds of force would hold it fine, but may have to be activated off throttle.

[dbrutherford]

If using an air cylinder, you can have it set up to pull back. Might need to flip the nozzle over so it is pulled to activate the trim.

[ADDict]

Well after using the bejesus out of my trim, I noticed a couple days ago the trim rod was bending. I caught it before it snapped, but it's not far.
I should have re-enforced it like Shawn and I talked about with some small stainless tubing.:banghead:

[cattledog]

i am using x2 guys trim and it works great , we have had some good waves up north and it sure makes the ski jump waves much easier, i like using the trim when slashing thru waves

[WFO Speedracer]

I have to interject a stupid question here,what do you guys use the trim for exactly,I have the modded stock trim and on flat water I have very little use for it,is it mainly a surf mod?

[X2guy]

On flat water I use it to drop the rear end down to make a larger setup wake. Also when hitting any type of wake it really helps getting the front end out of the water. I use it less in the surf as it has a tendency to flip me over to far and land upside down. (Remember our may long weekend ride cattledog). With no effort I completly landed upside down. I truely believe a back flip will be possible if I tried but I'm having trouble getting out in the right waves and having the guts.

Hey Mario, how were the waves on Sunday afternoon. We left around 1pm, and you were just pulling IN I think. But the wind had just picked up and I was wondering if we missed out on some good waves.

Anyway, was nice seeing you again.

Anyway, was nice seeing you again. THE WAVES WERE REAL BIG BY 5 O CLOCK AND ALL NEXT DAY I WAS LOOKING FOR YOU GUYS NEXT TIME HANG OUT A BIT LONGER

[gkeats]

Anyone have one of these to sell? X@ guy, are there any new ones still around?

[3rdgearpinned]

why not just ride with full trim all the time?

[kevbo]

Moving the bars aft does more good than adding a lot of up trim.

[X2guy]

Still have some...Ha...I just realized you sent me payment today Greg...LOL
