As a hull manufacturer, and probably the largest Gas Scale kit producer, if not the only one besides the hand full of glass gas scales sold by a few, I would like to shed some light on what I have seen over the last 3-4 years with Gas Scale. (and this applies in certain respects to all classes of hulls I made)
The first year or two of Gas Scale (2012-13 if I remember right) , it was strong in the PNW, and the Michigan/ Illinois area, then Indiana then Texas. Those are where the most of them reside. These are what I consider the core men/ women of Scale hydro hull builders, and cowl designers. They put the class on the map, and are still going strong in their areas/ clubs.
The third and fourth year (2014-2015), I started getting new customers wanting a gas scale (from many other states, and countries), but when they realized there were not cowls for the hull kit they wanted, they backed off and went another route. Lack of cowlings, or cowling molds being made and handed off to those who have the time to make them has been the #1 issue. Not a lack of interest in building, or racing. The cowls, are the issue. 1/8th scale thrives...due to the cowlings.
This year, I have noticed a pick up again in Gas Scale, but mainly the kits with cowling available. The economy has turned around, and people are building, and buying again. Again, lack of cowlings is still holding this class back..it just is, no if, ands or buts about it. If a person makes a cowl plug, get it in my hands, or RC Boat Company's hands, or Phil T's hands...get it to someone who can help the class grow!!!!
This Economy issue took years for me to notice with my business, even when everything around me was failing, including my own day job in 2011-2012, kits were still selling. It actually was amazing to me with as bad as jobs were, that people were still doing their hobby. With that said, around 2 years ago, things really fell down, and are only now picking back up. It was almost a 5 year time delay before it really hit home.
In closing...I will say this, and I am almost CERTAIN Zipp Kits, and RC Model Boat Company would say the same thing...80% of my business, is sport boaters, NOT racers. It has always been that way, and always will be. Honestly, my kit designs these days always have sport boaters mostly in mind, as I know they are the ones that come around more.
The thing that is hurting racing the most, and is the reason why I don't/ can't attend races...is the cost to do so. The boats are not that out of line as far as prices..but when you have to travel and spend $500-2000 in a weekend...forget that..Unless you are just really loaded, spending that kind of money, just is not in the middle class's plans. Face it, our economy, our government, everything around us has tripled, if not more in cost over the last 5-10 years, and our pay raises...HA!!!! Not even going there!
Well, that is my perspective from a supplier stand point as I speak to countless boaters every year, and this is just what it is.
