Miss Budweiser FE Conversion 59.4mph 4s Ride Attitude Insight Needed

**Gary** · 12-01-2014, 11:22 PM

I did a couple like you and they did the same thing. Those hulss where not really made to go that fast. 72mph was the best I could get out of mine but it was pretty crazy on the water sometimes.

I have one as well, two actually. One has not been converted yet. Mine does the high speed 'walk' too. I was going to try lowering the strut a bit but I am pretty sure it is from the Canard wings trying to lift the nose. As Gary said 'they were not designed for this high speed.

If it were me I'd try adding a little weigh at the 4 far corners... try a little at a time. Sticky wheel weights. Put masking tape down so they are removable. You may have to add power to overcome the extra drag. Will be a balancing Act. If this helps and gets you where you want, remove the weights and add epoxy on the floor in its place. Just an idea

Weight isn't going to fix it. I've converted a Miss Bud, Miss Elam, and raced also a Nitro Miss Formula. These hulls all suffer from the same issue. The entry angle of the tunnel is about 10-degrees, then breaks sharply about 3" into the tunnel and transitions to a nice 3-degree or so angle in the tunnel, back to the proper breaking point about 5" forward of the transom.

If you take some flat material (I used carbon fiber, of course), you can fabricate some plates to fill in the tunnel areas from where this break occurs up to the front of the canard wing, essentially making the tunnel-floor extend from the break forward, which makes it ONE plane at the front of the hull. This will get rid of that lifting point under the nose of the hull, resulting in a much more stable airflow under the hull. Should help eliminate that "sponson-walk".

Make sure all the regular things are correct as well. All of the ride surfaces need to be FLAT, and have SHARP edges. That's just standard.

That's great info Darin. I actually took the front canard off, put more of an angle in and re- fiber glassed it back on. Then I cut off the rear sponsons and made it totally flat and these things helped allot to keep it flat on the water.

What batteries were you running yours on 4s, 5s, 6s? I love this boat and to be honest I started out just wanting to have it to play with because most of my other boats are speed run boats and to fast to do figure 8's with and just carve out waves. I set my goal at 50mph but ended up with trying different props at 59.4mph! I haven't touched the original strut height , angle, or anything. I figured since i'm so close to 60mph on 4s , why not try and go for it you know. LOL

I see that we all are not alone here, I love the look and the boat period. LOL

What are "Carnard Wings"?

10-4 Captain....... Keep the ideas coming....... I'm not trying to do 70mph with it because then I would be back in the same "BOAT" (LOL) with having faster boats that I can't "PLAY" with on the water as loosely.

Thanks Darin........ can you send me pics of what you are referring to "Carnard Wings". I'm not a newby to this RC thing but I'm not a Vet so I have much to learn and this is my 1st Hydro. Thanks sir!

Canard Wing is the front wing... between the front of the sponsons...

Gotcha! Those are the ones the other gentlemen talked about cutting off, changing angle and fiberglassing back on. My question is how does that angle impact the "Walking" that occurs? I would think it would create the lift. Are the Carnard Wings disrupting the airflow ( i think someone mentioned something like that ) which is causing the boat to become unstable? Would adding weight on one side assist at all in your opinion?

I apologize for all the questions, I have a good idea with V Hulls and Cat's specifically so I am venturing out to the this Hydro thing so gotta get my knowledge level up so I know what my next move should be. Again with this hull, its just a fun play hull that I'm pushing 60 mph with so I am just really focused on creating a stable ride as much as possible if you know what i mean.

**Gary** · 12-02-2014, 02:27 PM

I also added a thin ride pad to the sponsons because the AOA was off so that helped as well along with taking off the rear upper wing.For me speed is not a factor...although I still kinda push for it, run time and fast full throttle ovals what I am after right now. I am in the same boat....my SAW boat drives me nuts and my little Miss Bud is alot of fun,no stress for speed,much much cheaper with $70.00 ESC'c and cheapo batteries. The boat is so balanced at this point that in 2 years of running her silly, I have never flipped it. Now I just jinxed my self LOL !!!

Hiya Shawn

, and as always, Thanks for the insight Darin

.....

I wasn't exactly sure what was causing the sponson walk on those Proboat bud hulls myself after installing updated power systems in them, but now we do

. As usual I am afraid it goes back to the age old dilemma of taking a vintage boat that was originally a low voltage low power design from back in the day and slap a new updated power systems in it and it creating a whole wealth of new problems because they simply can't handle that kind of speed and/or power .

For me it doesn't really matter much because I always run alone anyway. I may be playing with an old villain or super Hawaii or old Budweiser or even an old Nikko hydrofoil that can't handle newer faster power systems, but it sure is nice to give him just enough they got a little kick in the but because sometimes it makes them a lot of fun to play with

2 Questions for you:

1). What does "AOA" stand for?
2). Do you have pictures of the mods? Ride Pad?
3). Any additional mods made with balancing .... ex. weights added , battery distribution, etc.
