Thanks... I think if I were to do it again, I'd take the time up front to lay some reinforcing cloth to the inside of the ENTIRE HULL... In my opinion, it's layed up way too light for racing... It's fine for Sport running, but for all out competitive racing, you need more strength to survive things like this.

It COULD be repaired, but it would be a LOT of work. I already have the hull stripped down. Weighs just 5lbs 4oz, by the way... Would be fun as an FE hull...

Here are some action shots taken by Jerry Dunlap (gotta LOVE racing with a legend!!) before the demise... Was really having some fun!!

Since this will live forever as "the" Hypersport thread, I'm going to show how much I'm enjoying mine. Only thing I upgraded was steering servo and push-rod. Runs 35 all day. Not real fast, but it boogies.

great pic. ive noticed on a few vids as well that owners are running them without the canopy,looks awesome and i bet it runs alot cooler as well.

Ya know, I'm kinda new at this - the only reason I'm running topless is because I am still working out some kinks - I thought the cooling water wasn't flowing with the positive pressure from the exhaust, but it turns out the over heating was because I was running lean.

If you decide to rebuild this or another I wanted to recomment soldering the nose piece, or as we called them "ferrell". I always soldered mine on 60 and 90 nitro boats and never had a problem with the "Ferrells". I also found a guy who would weld an aluminum stub onto the tuned pipe, made for a very secure connection. Nice writeup with a sad ending.

Hi Darin,

I am new to the site as well as R.C boating. I have running RC’s all my life things such 1/8 cars and truck various scale size planes and most recently 1/5 scale stuff. I picked up a hypersport 48 and I love the thing it’s my first ever RC boat. The only issue I have with it it’s slow to me and I want much more speed!!! Believe it or not this is the only forum I have found on the web for this boat. I have a few questions about the mods you have done. I want to add a tune pipe setup.

1. Do you know quick draw Hot Pipe deep vee pipe (shown by crabstick) will fit in the hull without any mods?

2. How did you plug the hole for the can pipe?
3. What kind of pipe mount did you use for the aftermarket pipe?

I would really like to use the Quick draw pipe (mainly for looks) but only if it fits with no mods. But if not would you recommend your set-up?
Thanks for all your help!

1 => I looked at the QD Hot Pipe and I do think it would fit. Might require a few mods, and some careful thinking about how to get it to exit cleanly.

2 => I just used a rubber stopper pushed into the existing coupling hose, and ran a zip-tie around it. Was going to glass up the hole in the side once I had everything in place and working and knew I wasn't turning back.

3 => I made the mount myself out of some aluminum material I had.

The BIGGEST increase in speed and performance came from updating the engine with the Gizmo Motors GZ-1 Top-End Kit... EASY to install, and increased power up to around 5.5hp with the pipe... REALLY woke this thing up.

Hi Darin,

Did you try increasing your strut angle? Mine at neutral was running 31 and felt slow. With a positive prop angle it's on the chine and feels fast - running 37 last time I checked, but that was still only my third tank of gas or so. Might be able to lean it out some more.

Quick Q for Darin: How much work is it to install the Gizmo sleeve kit out of curiosity? I can't easily find info on the procedure.

Hey guys thanks for taking the time out to give some much needed advice to a newbie. I will to try out some positive angle on the prop strut, Also might go with the QD HotPipe and have the guy from my LHS install it for me just to retain to look (I not to great at fabing stuff). Quick question, If I upgrade to the Gizmo Motors GZ-1 Top-End Kit will I have to upgrade to a tuned pipe to get aleast 85%-90% of the 5.5hp you were getting. Once again guys thanks for the help.

I would definitely get a tuned pipe, without one you wont have much of a powerband due to the increased supercharging effect of a tuned pipe.

the QD or redline or CC racing Steel hotpipe will generally give you gains over a normal alloy pipe too.

Thanks Crabstick, I just wonder if it will fit nicely inside? I really wish more people who have this boat, were doing mods to it so I could have more to go off of.

[crabstick]

you can only try, the DV hotpipe is reasonably compact, but as the name says runs "hot".

Here are some good pics of a redline DV hotpipe..
