Hello Brad and thanks for chiming in,Ken, Tyler, Bruce,
I'm skeptical the leading edge of the rear sponsons is not the cause of any launch issues with this boat. While I can't speak for the Warlok in specific, the Warlok and the BlackJack are virtually identical for this vintage of Warlok. They both have the same origin inspiration. Jon strayed from that origin a bit, even before handing the design over to Chris Wood, who then took it in a completely different direction, where I never deviated from the original concept, aside from minor tweaks. There's more to this story, but that's for a different thread. With the design of this particular boat, at this time of its evolution, my BlackJacks have essentially the exact same set up, with that leading edge being within 1/8" from the bottom of the tub. We can give it a flat, vertical drop, and the boat will launch without a problem, assuming right prop and needle setting. There has never been any need for any Herculean throw for a successful launch. We have not seen that first indication that water was washing over the rear sponsons at launch, causing any problems during launch.
Thanks. Brad.

Tyler,Hello Brad and thanks for chiming in,
There may be more going on with my particular boat. Initially I built it just as Jon described and copied hints from other Warlok builds as well as Bradley's 21 rigger. The only change I made was running a square drive. I don't have a good picture showing the stock rear sponsons besides this picture below and if you take a close look the outer edge of the rear sponson almost looks like it is below the water line. It might just be the angle of the photo, but the leading edge was awfully close the bottom of the tub.

Compared to other electric and nitro riggers these designs have a fairly low tub height relative to the water level. I know that's on purpose, but it likely makes them more sensitive for poor launches.
I will say for the 2 of 4 heats at the Nitro Nats this boat was running strong and looked awesome. The other 2 heats I had a cable slipping in the ferrule resulting in DNS's. The last heat though it was strolling! I must have cut three buoys in different turns because I was thrilled with how fast she was going and did not care about the cuts.
Since changing rears and running a lower drag driveline I have not had any issues.
Bruce,We ran it the other day It would launch fine we were fighting the needle with some old fuel tried a few different props we need to get some fresh fuel and try it again.Once we get the needle right be a great little rigger.
Is that Brad Maglinger?My BlackJack never had any issues with launching or anything else for that matter.
Easily the best overall heat racing 20 hydro that I've had!
While I won't make claims of an 80mph boat, it did run very consistently 72/73 and surprisingly that was fast enough to win a lot of races
Brad needs to build more!
???Is that Brad Maglinger?
You said "Brad needs to build more"

Ok, sorry,Brad Christy!
