Hey James,

The V-24 is not a mono hull under the mono hull definitions of all the model boat organizations. Might be the only thing all three model boating organizations agree on.

He's got a larger fuel tank so the answer would be once you run out of fuel!

Status: offline 		Toyotatruckin, You might be suprised after you see the missvegas run. I ran today on the pond out back I normaly run on and there was a 4 to 6 inch chop on the water. This is rough for this pond. The Thundercat31 handled it with ease and then I ran the Missvegas. It handled it with ease also, didn't even have a close call with it. Installed the grim racer turn fin today and can turn any direction I want now. Still in break in as just ran the 5th tank of fuel through the engine today, but the boat is getting faster. One sprint today was 25 on the gun and at this speed running this boat is like going for a Sunday drive, as smooth as the cat with the chop I had on the water today. Jerry

Status: offline 		guys,

One thing I noticed is that the way the pushrod for the rudder is mounted now, i will have more throw or movement in one dirrection than the other..

Should the arm that the pushrod is connected to that controls the rudder be parallel with the back of the transom so there is equal amount of left and right movement.

Another way to ask the same question is where would the rudder arm be when the radio is on and in the servo in neutral position.

Status: offline 		The rudder arm should be parallel with the back of the transom or angled just slightly away from the transom. You don't need a whole lot of left rudder deflection.

Be careful making corrections to the left with the stock turn fin.

Status: offline 		The servo might be off-center. Put your rudder trim(s) in the neutral position and see where the servo arm is at. It should be 90 degrees to the case side. Once that's done, you can reposition the arm at the linkage at the rudder so that it is square to the transom or parallel to the strut.

I have the grim fin sharpened as per russ's description in the first post in this thread.There is a little movement in the fin but I have my fin flush with the top of the mounting bracket is this a good spot to start.

I am not even going to try the stock fin.

after the first hour or so of testing here are my results.

motor started and ran flawless and ran 2 tanks thru really rich and thin started in 1/8 at a time till she ran nice.

I had no turning issues at all as fas as loose or uncontrollable

I had the rudder slightly tilted out from the transom.The strut with a little negative thrust and the c/l of the prop nut parellel with the water pickup hole in the rudder.

The boat seemed tohave to be eased on the straights until the prop gets a bite.The engine seems to rev and then it's almost like it hooks up or shifts gears.When making a turn however ,The boat would slow down and the prop seems to cavitate (for lack of knowing what is actually happening)the engine speeds up ad you loose speed.

I tried the rudder in different positions and tried the strut up and down and it seemed to work the best in the location above.

I would like to try some neutral and positive thrust angle put when I loosen the coupler the strut angle has to be forced to either get neutral or postive thrust.

is there a trick to get neutral or positve.

Any input would be appreciated.

Thanks
Terry

And does this ever get changed?
If i loosen the cap screw and lock nut my rudder can be tilted in and out.

James,

I tried seting my strut with a slight bit of positive like you suggested but i was not comfortable forcing on the brass tube that houses the drive shaft tube.I'll try again tonight if the rain holds off.

I was making all my adjustments one a t a time but could have been making too much of an adjustment per try.

Status: offline 		Yes Terry it seems alittle tuff to put some positive rake on the prop and move the strut around "like you might break the shaft". Did you take the shaft lose from engine to stop binding? I did not see you mention doing this. Second it is very nicely machined by AquaCraft where the strut meet the drive shaft tube. You can remove the strut and sand the inside of the strut tube...not alot, just take off the edge, also the drive shaft tube its self. just run some 600 around the end of the tube to not make the end of the shaft so blunt. when you do this you will see that the fit is not so tight.

Now on your rudder....let her lay back a bit...this will not affect speed or your performance in the straights....it will only tighten you to the water when you turn....this is good, but yes it will slow you a bit.....your issues are not with the rudder.....in you prop setting and angle i believe..

Status: offline 		Hey Terry....burning off zip ties on the Vegas muffler I assume you are talking about is not normal no.....you have a heat issue here. do two things....check to make sure you have not picked up some trash in the pick up on the rudder, and also see that to have flow thru the head on the 18 OS power plant. First remove the rubber line on the rudder and blow thru it to see it is clear....if so...then take the Vegas out and run her....bring her in close to you when operating, and see your water flow from the outlet tub on the port side "left" of the Vegas. you should see underway...a nice constant stream of water shouting out past the sponson. I believe in my photo gallery I posted.."Miss Vegas at Half Throttle" you can see this water flow I speak off. If this post does not help you...I am sure the phone call we just had, will.....LOL....thanks for the call and HoooooRaaaa for having your friends order the Vegas in your neighborhood.....Lets see if next month we cant come up and get with the vegas's there....hope this helps...

Oh Ya....almost forgot....We remove the head on the Vegas last week..to discover that the inside of the cooling head has many catch places for debris to collect....see that you cooler is not jammed with trash.....although you will have water to engine....it may not be enough....and this will not show clogging, but does not allow enough water with small trash collecting in the head....in our case it was duckweed....LOL and dandelion pollen....

Status: offline 		The Wing?

Our test result of the wing on the Vegas....in a open one here at Twisted Liquid....Does it need to be there? Well it depends on you....it works for me because I am a power driver...I push the Vegas and I need the extra down force to stay in the water, but on the other hand, my other testers say take it off......DRAG!!!!! No real meaning. So in this case I say....take it off... if you like it off, leave it off....but for the record....indenticle Miss Vegas boats....one with tail...one without....I won with the tail installed. But also for the record...only because he flew off right behind me as he tried to catch me....so you figure out if you need it or not....MY U8 Vegas will keep her tail....plus I think she a bit more SEXY with it....

P.S. Thats a SEXY VEGAS xStream70....NICE!!!! oh is the 70 how fast you plan to make her go? LOL
