Unlimited hydro rear wing

[ChuckG]

Can someone please clarify for me, why almost all of the hydros out there now don't have an unlimited style rear wing? Is it because it affects the handling of the boat too much? Hydros always look infinitely better with the wings. They look like they are missing something or unfinished without them.

I agree with you mostly. The ProBoat UL19 looks decent with just the fins. But I don't have an answer as to why...

wings are for scale hydros. model replicas. They're not for function so sport hydros dont use them. scale hydros in model form are a kind of a show-boat class that go much slower than sport hydros without wings.

We did a lot of testing on rear wings. It adds stability to the hydro and helps prevent blow overs in full size boats. In model size it doesn't seem to help.

Good info Lohring - Is that a printed model? Have been developing something similar here lately too. looks Cool. Have been not using the wing though..

That was a 1/4 scale test boat for a proposed full size electric record hydro. At that time we thought we needed to run lead acid batteries. When the rules allowed any commercially available battery, we researched lithium polymer batteries and realized we could run a standard outboard hydroplane. These days we could get an easy 500+ hp electric setup with a standard hydro design. That basic design without the wing was used on a record setting gas hydro.

I think there are different reasons why folks might opt to have no wings on their boats and they do definitely have an affect on the boat. Whether it's a good or bad, like anything else, depends on how you set it up. There's no way you can have a wing surface traveling that fast on a relatively lightweight boat and have it not make any difference. The weight of the wing alone is going to make a difference on a boat's performance. Many people like the look of a wing, but are afraid they either don't know how to make it adjustable or set it up with the boat, don't know how to deal with mounting it to the boat, or have told me they don't want to have to deal with the damage to it if they flip the boat. As a scale racer, those are the reasons I've seen and heard from other scale racers. It's one of the reasons the 8255 hull is so popular as a scale build. It's one of the pickle-fork modern hulls that is wide and ran without a wing in the front or in the rear. It's an easier build and It also makes a ton of different boats.

Thank you so much for all of the in depth information. Finally, someone has answered the question in complete detail so that I can understand the issue. I've got an old MRP Miss Budweiser that I bought back in 2008 on eBay. I took extra time to reinforce the mounting base of the rear wing before attaching it, but for the plans I have for it speed wise, I still don't know if it will hold up. If it doesn't, I can always make a new one out of composite materials of some sort. Thanks again for the great info!⛵
