Hi Kelly,

Seems like the prop depth with the M435/3 was the 7/8" I normally run. I haven't done much more experimenting with that prop. I don't believe I've experienced any air leaks through the bushing in the pull start.

Russ Williamson now has the Miss Vegas I set up for an O.S. VZM 21. I was talking with him today and he said he's got it running pretty nicely. He's put a 3rd channel mixture control on it.

I'm hoping to bring some of this cooler Northwest temperature to Wichita in a couple of weeks.

Hello Jerry.
I have a question for you I have miss vegas its about two weeks old, run maybe six tanks of fuel, by the way this is miss vegas is number two, as great planes replaced the first one.my collet assembly seemed not to stay tight like it had a problem, the 12mm wrench that can with the ARF kit didnot fit the fly wheel nut looks like poor casting,so I used a adj wrench to snug it down but it never seemed to stay tight, today the whole drive shaft assemble fell off into my back yard pond, I dont want to spend money shipping boat #2 back to Champaign, But I think hobby services needs to address this issue, what do you think.
Thanks and God Bless.

Hello Nitro,

from what I am told AquaCraft plans to change the coupler in future Vegas boat, but its takes user of the Vegas to get a change made in the manufacturing of the Vegas...One Person has issue, not a problem, but more then one, AquaCraft will change it I am sure.

Short Note on pond meeting today. Kelly has got his Vegas on a rail. Was the only Hydro on the water that could handle the chop. Wind was 20 today at our pond. LLumar, Bud, And Thunder Cat 31...all had a hell of time.."Our Vegas was left at shop, we were testing and tuning some of our port time jobs on ProBoat's today"

Wish we would have brought her out, but watching Sam run was nice. In a video of Sam we will put up, I was doing editing tonite, it's funny..you hear Kelly six million times...slow down, slow down Sam, slow down!!!

sam is Very agressive, but in control for sure.
We will be putting up the crash videos in couple days...some amazing wipe outs...but no boats lost...Low and behold Sam was running strong....only blew out twice, but thats because the Vegas does hit a point were no matter what you do...The Vegas turns into a plane at some point.

GO VEGAS!!!

While you're waiting for an answer from Jerry, it would be a good idea to contact hobby services. Sounds like you have their number already.

When I tighten the flex hex coupler on my Miss Vegas, I really "snug it down." As Chuck stated, reporting issues to Hobby Services at Tower is the only way the company can document things about the Miss Vegas.

Hobby services have replaced my drive line componenets and coupler but a better coupler would have been nice.
If they make one to fix the problem that would be great.

They helped me out with some other Nitro hammer issues as well.

They seem to be very good people to deal with.

Thinking..........

You know we might be able to cut off, say, 1/8" or so of line off the water line (fuel line) and slip it over the cable between the coupler and the stuffing tube.. If the coupler comes loose the fuel tube would hold the shaft from sliding out the back of the boat.

Great idea. Do you think the fuel line will withstand the punishment if the line comes loose? Thats a bunch of rpms to hold back.

The problem with wheel collars is the set screws have been found to deform the flexshaft. Listen to the voice of experience, Grimracer's, and try the fuel tubing method. Works great and doesn't get much cheaper!

Edit: I hate it when I can't type!

Bruce,

Its not so much the RPM but the speed of the boat at shaft ejection.

man im just diging me a bigger hole...

Fuel tube for sure... also you want the rubber tight on the shaft................. im done now..

hello all, quick question, 2nd time running my new vegas. trying to make all adjustments i have been seeing in this forum. had it at the lake today and just found out about the prop angle. this ajustment is very mynute. does it make that much difference in the performance? also, the motor seems to be working harder than the boat is moving. I CAN SEE THE BOAT ACTUALLY GO FASTER AT TIMES. when i first tried the boat, it would take off in the corners and die out in the straight away. any help here maybe, or do I just keep at it (ADJUSTING). THANKS. Also I see these boats in the pictures with the strut very high. i tried this and got nothing but cavitation (bad).

Not too far, perhaps 1.5 hours. More important, the nearest club is North of Greensboro in Walnut Cove. Here's our web site: http://www.geocities.com/ptproptwisters/ . Our next club race is August 13, think about heading up there. Not sure what boats I'll bring. I'll definitely have my TS2 and 40 mono, possibly my sport 40 and cat. I may see if I can bring my new Vegas to run with the pseudo A monos. They owe it to me since I've let them run in the Sport 20 tunnel heats just to give them more water time.

The strut depth on my Miss Vegas is 7/8" from bottom of hull to c/l of strut. It takes 5 or6 tanks of fuel through the engine to break it in.

When you get a hydro operating near its performance limit, very small changes can make a huge difference. For example, at the second club race of the season, something was happening with my sport 40. I had made absolutely no setup changes since the last race other than new bearings in the engine, which I think made it run better. I could not keep it on the water. By the end of the straightaway, it would go airborne. One time it did a complete 360 in the air and ended up still running! To cure this I lowered the strut a bit. This raised the back of the boat and it stopped going airborne. This is just a general answer, Jerry and others will probably elaborate on what they've found to be best for the Vegas.

Prop shaft angle and height....Here is what works for us. In testing and tuning of the Vegas we found that placing the Strut C/L 7/8 from the bottom of the Vegas is perfect, but of course the smoother the water the closer you can come to the bottom of the boat. As far as the angle of prop shaft. We have ours set at 1 degree positive. this makes the front of the Vegas rise a bit to get over the chop in water and boat wakes. Below I will list our exact set up for our Vegas.

Twisted Liquid Racing Vegas Set Up

7/8 from C/L of strut to bottom of boat.
1 degree positive prop angle.
Rudder tuck is a 4 degrees under boat.
Turn Fin tuck is 22 degrees under sponson
No Tail fin
435/3 prop

I want to take a second to tell everyone how cool I think it is that all of you want to make your Vegas fast and fun. I realized the other day at the pond and weeks in the past, that every body wants to go faster and faster. It seems the serious hobbiest have this in there DNA. What we have created here is a bunch of competitors to us a Twisted Liquid. I am just blown away at the fact that we were the fast ones weeks ago, but now look at competitors that are passing us. I think its a wonderful thing, and when I see guys in other parts of the world doing the same...its a real thrill. When people work together, you get fun....Keep em Smokin

GO VEGAS!!!

twisted.....i dont have any upgrades (YET). Does the stk rudder tuck that far? it moves ever so slightly back and forth. Is the stk turn fin ok at 5 degrees (or just slightly angled inward)? just trying for now to get the boat to go accross the water like its supposed to. thank you all for your info. I will be at the greensboro nc races on August 13th, Thanks

Vics,

We have 3 Miss Vegas between three of us and the first thing we did was replace the turn fin and sharpen the new one.
We have the strut aprox.7/8 " from the bottom of the rear of the boat.
I removed the styrofoam from the rear turbine and removed the fibreglass in that area.
I left the small peice in the top of the canopy and that will float it but test it in shallow water first.
I sharpened the rudder and strut and am still using the stock prop.

MY buddy has the same mods except opening the rear of the canopy or the small vents in the side.

The run almost exacty the same and the engine are almost the same temp.

Ours ran like yours at first but just kept getting better the more fuel we put through them.

It did take some time but i am a newbie and got them dialed in.

My friend was beating me around the corners and straights but last night was the opposite.

Good to hear you have the Vegas boats working well. It does take time to get the engine broken in an the hull dialed in.

We have the boats working well and the engine temp varies but they have been up to 133F is this a reasonble operating temp for these engines we are running 30%N. The os #8 plugs seem to work the best in our climate/sea level.I've tried several types and heat ranges.
The odonell red dot is close..

As james has said in past posts the faster you go the less water comes out the pee hole.
I am contemplating all the twisted updates but for now we're running great and pretty much stock.

Kinda like nascar

Thanks to everyone that has helped me out...

Terry
