There are no other motors that qualify. So if you have an old uncut K&B with the proper lower you qualify. This class is dead and doesn't need to be run anywhere as it CANNOT grow. In the southeast we have adapted to an "outlaw" .45 class that only requires a can muffler. Any powerhead or lower. It is a great tunnel class that boats run and finish more often because of size and more over reliable easier to tune motors. Less brute acceleration than mod but respectable speeds. And obsolete but plentiful K&B motors and older tunnels compete well. Sort of restrictor plate for RC boats.

in 3.5, tower sells complete outboards, aircooled/watercooled os max and thunder tigers, are those allowed because they have lower units? unlike the nova rossi 46 or cmb evo 45, which have no lower unit?

and when will namba change old rules have no place in today's hobby, given engine availability?

with nitro dying off, seems ridiculous to make it impossible to run a class that was so wildly popular in the past

I was incorrect as there is an option. Twin OS 21's qualify for Namba B stock class. Newer outboard options are not complete with a lower and exhaust system and production numbers so they do not qualify. When K&B was in it's prime, the cost and numbers made the class popular. Even in the .21 class a stock OS is $350-400 and add a $300+ hull with support equipment, $40 a gallon fuel and $5+ glow plugs we are seeing a decline. Outboards with low cost and simplicity to rig (no strut & rudder) drew a lot of new boaters back in the day. I am not sure any new .45 with lower and exhaust would be able to sell big numbers as it won't be cheap. As I said the class is dead. Adapt some restricted rules may give it a resurrection. RIP stock and hope for an afterlife in Superstock or Outlaw rules. Close tunnel racing with reasonable cost is here in the SE but not growing much anywhere else.

i agree, cost has prevented alot of people from participating

but that does not justify having rules that reflect a different time with goals that do not make sense anymore

people who do not mind the cost should be allowed to 'buy in'

superstock is patched together motor/pipe/lower?

If you find 2-3 other people in your area that want to buy in at any cost then twin OS's are there. I believe the premise for "stock" class rules was to level competition and keep cost down not having to buy the latest and greatest pipe, carb, motor, to keep up with everyone. Cost. Rules should have a shelf life and need be renewed from time to time as changing them is not popular. When real numbers of people buy in classes will follow.

The .45 class run in the Southeast is simple, any .45 with a can muffler. I have seen Nelsons, Rossi, Nova Rossi, and CMB's with K&B cans, and some pretty fast 8701,8702.red and gold heads still hold their own. The muffler is cheap and levels the field.

So easy a keyboard racer can do it - Good times

I got a 3rd at the first SOS race with a middle of the road boat for sure, thanks Mic

My wife ran for years a 8701 modded just a slight bit and won alot of races, I used the stock muffler on her boat.

There is no need to change rules. There is a stock class and a open class. You fit in either one. A stock boat can run in open. What your problem is people who want to run the class. Not the rules. If you dont have enough people in your area to run 7.5 Mod tunnel, then how does changing the stock rules help that? Lack of motor availability is not what killed off nitro. Because its across the board on all classes on attendance.

Lennard,

Everything you are saying is 100% correct. I have been pondering some of the same questions for a couple of years now. I agree with you. Changing times is no reason to sunset a class that could be just as popular today as it used to be amongst rc tunnel racers. There is such a vast offering of powerheads, and now lower units as well, there is no reason these stock classes can not be resurrected once and for all. Mic is correct as well, the Superstock class is very popular in the southeast and was a result of out of the box thinking to get some type of stock class back in tunnels. It has also been very popular amongst the gas classes. Its a way to bring novice and seasoned racers together on a single unmodified racing platform where setup and prop experimentation can get you into the winners circle, at a reasonable cost. I had this very conversation with Mark Grim at the Huntsville IMPBA Internats earlier this year. We discussed a really easy route to re-ignite these stock outboard classes. With such a vast amount of used and new lower units readily availabe in multiple venues, the simple solution would be to modify the stock rules to allow any previously manufactured lower unit, regardless of manufacturer, as long as it follows the stock lower rules, to be utilizied. Then the existine engine manufacturers would only need to offer a complete powerhead/pipe combination similiar to the OS OB, to be accepted as a complete stock OB. I am sure Nova would join in, as well as many other manufacturers, as the only missing link would be the stock one piece header/pipe to be sold with the powerhead. No need to spend $50-75k on lower mold developement and casting for a new lower unit, when there are plenty commercially available today. You will see such a shot in the arm for these classes. Dont be surprised of they become as popular as the A OPC and B Sport classes at most of the NAMBA and IMPBA races today. I could take a Nova Sport 21 Engine, 5 or 7 port, add a Nova designed pipe/header combo, and have a complete 21 Sport or OPC on the box available for about $295. These would have one peice, non slugged and tuned cranks, similiar to the OS, which helps lower the price substantially. We could also have a one piece 46 crank designed and built, that would drop the 46 OB Powerhead price by at least $75 or so. This would put a 46 Stock Powerhead, with a one piece header/pipe combo, at the same price or lower than the modified powerhead only. The costs for entering these stock classes would not only be limited, but minimized substantially as well since modifying would be prohibited in NAMBA, and limited in IMPBA. Manufacturers would be all over this opportunity. All we have to do is allow any available lower unit that meets the same stock limitations.

that is what i was kind of thinking...not exactly...

and my only concern was unavailability of stock motors for new/interested boaters that cannot find K&Bs

the few people I have spoken with told me that this was discussed 10 years ago, and that there is little to no interest in setting up these types of "stock" motors

rationale for not changing the namba rules was to let those with K&Bs run their non piped stock class; meanwhile, those with other powerplants with pipes have mod class
 
What Lennard is talking about is the pure stock class that required a complete unit and box stock power head. Good idea that work well for a time. But, no one wants to run stock anything anymore. Even if the complete engines were still being made it would be a dying class, just for that reason.

Super Sport or "outlaw" is a great idea. I have seen internally modded .21 outboards with no tuned pipe run as fast as mod boats. I see no problem with a class that allows any power head, any lower and no pipe.

The problem with the outboards now is the cost. At the risk of ruffling feathers, upwards of $500 for a tunnel hull does not help. That takes the "hobby" out of it real quick. There were a lot more racers as well as non racers running outboards when the engines were $100 and a boat kit was $50. Those days are gone. Hate to say it but it is a fact.....when the tuned pipes came out for outboards that put them into a new performance level. Up until then they were the slower, door slammer hobby class of RC boats.

Mark, I am working on the tunnel hull part. I have fiberglass 20 Lynxs in stock for $325 and Leecrafts for the 40 and 60 class for $360 and these are RTR, ready to rig so the $500 tunnel days are over...

The class for all who started racing in it called it outlaw 45 than someone decided to change the name, it's a grate class

2018 Tower catalog lists the O.S. 21 XM VII Marine for $449.99, ad at least $150 for a decent radio and servos, and you're looking at $725 to enter NAMBA's A OPC tunnel class and you still don't have a starter, fuel, equipment. So, you are correct,"the $500 tunnel days are over."
