    RE: AquaCraft U-18 Miss Vegas Hydro Thread_Make it Fast!

    Take it easy on the Aqua .18 mods.....it doesn't take well to heavy mods and the weakest link in that engine is the crankshaft...trust me, the rear of the crank will say bye bye to the front end of the crank and make a drive through window in bottom of your crankcase real easy.

    RE: AquaCraft U-18 Miss Vegas Hydro Thread_Make it Fast!

    We just race for fun within our club, no points or anything. Two classes: Stock RTR Hydro and Mod RTR hydro. THe only thing you can change in the stock class is the prop and fuel tank. In our mod class, the sky is the limit - any engine size, equipment changes, etc.

    Heck, we even had one guy put a OS 46 in his! Unfortunately, he had a major steering malfunction, and it drove straight into the side of a concrete culvert shortly after launch. So, we didn't get to see how it would really run. Should be interesting though!

    mod is mod i guess!!!!!!!!! that cool though! we have to stick to .18 in mod class round here, not only that but the motor has to be under $100 witch really takes the fun out of mod class.

    Anyone tried the new Deuce engine in the old boat yet?? It is less than 100 bucks... I am curious to know how it compares to the old engine...my guess is that it would be slower.

    The new engine is faster, especially with the new pipe. But, the trick is to keep the jetting consistant. It needs a different (O.S.) carb.

    Well...I have not found the needle on the one I got for my kid yet. I spent a lot of time trying to find it without noticing that the carb was not opening all the way.

    My point...I have seen a few folks mention getting speeds over 40MPH with the stock engine and a sponson mod on the old MV. The deuce has a sponson mod built in, and most of the speeds I have seen posted are high 30s. 4 to 6 MPH slower than the speeds I have seen quoted for the AQ engine.

    It will take some time, but I will eventually get around to doing some more testing on the different engines, and see whats what. I was thinking that the new pipe was holding back the new engine.

    Anyhow, how about sharing what you did to compare the engines to say that the new engine is faster...

    according to tower...that shaft is only 12 inches long and the vegas shaft is 15.4 inches long.....however, if you have modded your engine mount and location, all bets are off...

    No. A 3/16"(.187) shaft is what we used. I have an Aeromarine one, but you could also use Octura or a Hughey. I bought mine at the LHS. The Hughey and Octura ones are available at www.offshoreelectrics.com

    You need to remove the teflon liner as well when you use the 3/16" drive shaft.

    RE: AquaCraft U-18 Miss Vegas Hydro Thread_Make it Fast!

    Ran the .32 again yesterday - second time out. I am still running the Grim 42 x 55 prop, and we are starting to lean her out a little at a time. She is definitely picking up speed - blew over once on a full throttle pass. Decided to put a little negative angle on the prop to keep the nose down - worked great. Nice and fast, but no blow overs. Lowering the turn fin helped alot as well. I tried an M445, but hit the rudder and dinged the prop good. I had to restrict the rudder travel a little (with the radio) to avoid that. I should still have plenty of rudder for the turns still. I'll try that M445 next week when I get it bent back into shape. I will also be trying the ABC H-4(42.5mm X 66mm pitch).

    Will try to get a speed on her. My GPS flew out out of my R/C truck and hasn't been the same since. We have a radar gun available as well. I'll give that a try next week.

    My Aeromarine drive shaft was 18" to begin with, and cut down to the length I needed. Since all these mod boats have slightly different engine placement, one size doesn't fit all. Once you get the engine mounted, then you can cut it to size. I also use an Aeromarine coupler, along with the stock flywheel. I will try to get the part number for the collet. Probably not till Monday though.

    Flex Coupling (collet): Aeromarine No. AEM1732 /OS21 X 187

    There are a few you can choose from depending on you local hobby store, but I use the Octura .150 flexshaft with the 3/16 stub. I also use the Octura .150 collet. The flexshaft has to be welded/silver brazed in with the kind I use, but I think they make it already welded too and about 18 inches long...mine is exactly 15 3/4 long (from end of flexshaft to the end of the threaded stub) after I silver braze and cut it to length and goes up into the collet until it hits the end of the crankshaft..also I leave about 1/8 inch space between the drivedog and strut and my engine is in the stock position. If you do go with the Octura brand, pay attention because they also make them in the .130 size too...just make sure that the collet and flexshaft are the same size.

    TrEsPaSS: Are you running the Deuce Vegas? I measured my MV Ver2 flex shaft and its 15.5 ish inchs. But maybe with the different flywheel and collet that makes up for the 3.5 inchs?
