6 ft Miss Budweiser hydro

[shrop2222]

New to forum. I'm trying to find out info on this hull. Got on a trade. It was gutted but apparently it did at on time have a gas engine. I want to make it brushless and have been searching for the right motor and esc. Would rather hear from the experts than waiste time and money on my own. 5 " rails. No marking on who built it or anything. Found a piece of wood in it while cleaning up the deteriorated foam. Any help would be appreciated.137065

Do you have a budget that you want to keep?

[Mxkid261]

That is so awesome, curious to see what you do with this.

[srislash]

ProBoat did put out a big one but I think it was 4ft

I think I would start by seeing how many mah's you can squeeze in there. It is going to take quite a bit to get it up on plane. Geez I would think 20,000 would be a small battery bank. Maybe 12s and 20,000mah. A 600kv 2230 should do the job. ESC though, Mmm.

[ron1950]

Think id go with a 2028 on 10s but not sure of the esc

[shrop2222]

Im trying to stay under 1k. Depending on the motor size, I have space to line the inside with about 10 hard packs. I have no idea what size prop to use. I ordered 1/4" drive system hoping it will hold up.

[srislash]

1/4' drive will be fine shrop. With that budget a Castle 2028 would be the ticket. Can you fit any of those packs in the sponsons? And how many packs do you own currently and at what cell counts?

[shrop2222]

I can fit them 2 wide in the sponsors and still reach them. I have to leave room to replace the flotation foam.the rest I layed out on the outside rails as forward as possible. I currently have about 6 2s packs 5200mah and 2 3s packs. I would be buying fresh packs.

[srislash]

So, a car racer guy are you? That's cool. You may be best plugging 2s&3s together for fitment in there. If getting new batts that is going to put a huge hole in your budget. 4x 5or6s (decent quality) is going to take $500+. I would look into maybe a Swordfish 300lite and look around for a deal on a 2028, they can be found.

[shrop2222]

Yea I know. Been running around with the Spartan on 6s and that boat is a blast. May compensate some cost by selling some of the car stuff. $200 sound about right for 2028?

Yeah, may find a better deal. I have seen $170

And Simple Green in the spray can to clean out the old gas goo,;-)

[shrop2222]

Didn't take too long to clean up. i don't think the boat was ever run. Can i get away with a fan cooled esc? The hull interior is so large and i have a ton of air flow due to intake.

You will have to plug that intake.
Boat should be air tight.
If or when it flips, you don't water running in through that intake.

Also plug that exhaust hole.

thanks for that info.

OP, I hate to break it to you but you are getting advice from folks who have zero experience with a boat like yours. In fact few FE folks anywhere do; some others not posting here may have successfully built a 1/6 scale boat but yours is 1/5 - much bigger. This is a build for an expert, not a relative newbie like yourself. Running an RTR around the pond does not make you able to complete this build successfully. If you do not understand the need to seal the hull, then you are not ready for a successful build.

While a cat or mono can at least get on plane with a marginal setup, hydros can be difficult to make run if the design is a bit off, if there is not enough power, or if the setup is off just a little. I can guarantee you that you will not be happy with the outcome unless you enlist help from those who have actually built large 1/6 scale boats. Plus there is probably a reason why we don't see this hull running much at all, it may be cool looking but be a poor design for available power. (Actually I seem to recall seeing this very hull in a build a year or so ago, either here or on another site.) It's your boat and your money, spend it as you like. You've been warned, I hate to see a fellow boater headed for failure. Whatever you decide, good luck.

[kfxguy]

I was thinking a 2028 was too small myself but I didn't comment because I have no experience with this hull.

[Doby]

While whatever you choose to do is your decision, personally, that hull would look nice, cleaned up and hung on the wall for display purposes.

[shrop2222]

Not trying to break a speed record, I want to enjoy it on the water. it will become a man cave item. I want to build a 1/8 hydro.

[srislash]

Jay kind of shut me down there a tad. Man cave item is good. But always good to day's he runs'.
Awhile back I was looking at the aforementioned ProBoat 4ft hull locally for cheap, look up some vids and see how they run. These large hulls are so buoyant with the light gas setups they just kind of run different at nominal speeds.
Jay is right, hydros are a completely different beast to setup. But really, look up ProBoat 1/4scale Miss Bud on YouTube or Google.

Here's a link to two built by mudl and Christian, some very costly hardware though. Hard to build a "budget build" with this size hull.

6 feet? no way,

in my opinion at least, way too small

Pretty sure there is one of these in the for sale area. It was awhile back but you could check.

And it would depend on the KV, Flier is the only ESC out there above 16s

I have a TP100. I was holding on to it for my "Larger" project as an alternative to the LMT3080's but I could let it go for the right price. You still need a pretty beefy ESC though.

[shrop2222]

What are you looking at for right price?

[Hotrods]

I would be curious as to how this boat is built. I have my concerns as well on the construction.

[shrop2222]

Boat is all fiberglass with 2 wood spars running from rear of sponsors to transom. 3 crossmember.

[jj2003]

I could do $450 shipped. It's one heavy motor......!

[flraptor07]

I have a little experience with larger Hydros, I built a Mountain Hobby's 48" Hydro with a Leopard 56110 1100kv on 10s with a SF 300 Pro Plus ESC the boat ran about 70 and it was heavy @ almost 20lbs.

[Fluid]

Uh, 48" is a long way from 72".

[nichismo]

If it were mine, Id go with a twin motor setup, perhaps dual Leopard 5698s, or even better, 2x TP Power 5670s, perhaps 750kv or 820kv. the latter you can pickup for around 160$ brand new, pretty darn good deal. Just need powerful enough ESCs to boot, but this thing would MOVE with that setup.

https://www.youtube.com/watch?v=B5jBwhMZ3V0

This boat^^^ is wicked fast and its about 61 inches long by 30 inches wide, and is a whopping 40lbs!! running the aforementioned dual TP power setup, and only 200 amp escs each. 10s would be ample too id imagine

[shrop2222]

Any good websites for the gearbox?

A few of us here in the Pacific Northwest built some 60" FE scale hydros just to see if it was possible. It was a few years ago and the availabilty of HV esc's were miniscule compared to today.
Key is weight and prop size. With larger FE boats the margin for error is much smaller. Don't worry about making it watertight as long as your radio and esc are protected and you running in freshwater. Start small on your props and work your way up in size. I think a Castle 2028 on 10S2P could be workable if the hull isnt too heavy.

[leonard feeback]

If it was mine, I'd put on a shelf and save myself a lot of money and grief on a dead horse. IMO.

[shrop2222]

I think this project is going on the back burner. Too many variables and opinions on setup. It's going on the wall. Think I'll start building a 1/8 scale hydro.

[leonard feeback]

Much better idea, a lot of good boaters on the site to help you. Much easier to transport also.

[ls1fst98]

id put a gas motor back in it and let her rip!!! or do twin 2028s or similar.

[nichismo]

Theres an incredibly abundant amount of information on 1/8 scale hydroplanes in general, though not quite as much for brushless and lipo powered renditions, but still alot nonetheless. Its a much better route to go with if your are overall unfamiliar with the nuances of building like I was, and just the whole process of learning and gaining perspective will grant you very fulfilling understanding of it all that will prep you for a project like this down the road should you choose to tackle it.

I didnt really consider the whole transport issue of these things too when I first starting going to the lake with my 1/8 scale. Although 15lbs doesnt sound like much weight, it was suprising to me how difficult it actually is to simply carry the boat from your car to the water.... not to mention hydroplane hulls in general (and especially scales with the extra wings and offset ride surfaces and hardware, etc.) are just very cumbersome and awkward to handle.....
