Gas Scale hydro builds

[SayMikey]

I'm my opinion the t boat class is a joke. Until guys start putting up. 5 bucks and tear a few down. Cheating will remain. Gas scale will be 5 mph faster sure but. Much more than 65mph and your looking at self destruction in a crash.

31cc with GX engine specs, I like it. It does leave the door open for some really serious horsepower. The big engines will be more forgiving on setup for the average guy. The drawback is the better than average setups are going to be fast, maybe faster than people are going to be happy with. Having spent some time playing with a 30.5 zen, I see no reason these boats won't easily top 70 mph. I watched a thunderboat with a good G-1 engine run 77 dead stable last October in LA.

If you're willing to do some research and a bit of homework, there's no reason guys can't build their own 29.5 or 30.5 in the 7.5 HP range for under $400. Significantly more if you're willing to work at it. But you have to be willing to do the work yourself.

For the guys who don't want to do the work themselves, they'll be paying the guys who did do the homework. Horsepower will cost you, time or money, your choice.

Lohring, can I still drive your new boat in the fall? I'll even bring my own engine and pipe!

Phil, I agree. A round nose may be the trick setup for the class if setup properly.

See you guys at the D-8 meeting this weekend.

I understand what you are saying about price on the type of motor you have Mike. But whats to stop someone from getting a, lets say M&D cast engine full mod still under the 31 displacement? This can and will get out of hand some people have deep pockets and will shell out the bucks to win at all costs. When I first saw this class come together I thought it would be a fair and cost effective way to run scale. I am sorry to write my concern on here but I have talked to many people interested about getting into the class, but they and I feel it is going the wrong direction. I write this with the most humble of respect to Marty and all that have worked so hard to make this work. However it is hard for me to answers question posed by interested people about the class. So I am asking, and the main opinion for all was speed. Not that they wanted more speed but all felt anything over 60 was way to much. Please Marty, Mike, and Phil I am not trying to be rude or be an a$$... just would like to know what is going on and be able to return some answer to myself and those interested in the class.

Thanks Don McKay

Don What would you propose? Not a stocker? I would like to mimic the West coast or Namba rules so when possible someone could run either org and be in the hunt. While its possibleI dont see a gas guy spending the time and money to build a realistic boat and then put a crazy fast motor in it. After all we both know its takies a lot more than speed to win in the 1/8 scale class

I thought the old rule with GX 1 engines was fine. The solution if you want bigger engines is to allow GX1 and G2. Everyone is afraid of checking engines. It's easy with gas engines compared to stock outboards and the threat to check the winners seems to work. Applying the PNWTBA's unsportsmanlike conduct rule will help as well.

Hey Phil, With the engine bay offset so much to the inside of the boat are you mounting the strut in the middle of the engine bay or putting it in the middle of the boat? Also are you centering the motor in the engine bay or offsetting it?

I am looking at centering the motor and putting the strut in the center of the transom and putting the rudder on the right side of the engine bay(looking from the back of the boat)

I will keep the motor on center in the engine well and set the rudder 3 inches left of the strut. This keeps the rudder mount bolts inside the engine well.

If you wanted to move the strut and inch to the left it would work. Set the rudder on the right side. What motor will you use? check how the exhaust would exit.

The exhaust can exit right of the strut using a 100 degree header on a Zen or a rear exhaust motor.

"I'm my opinion the t boat class is a joke. Until guys start putting up. 5 bucks and tear a few down."

Hey Mike,

If a boater wants to cheat in any class, they will find a way.

For those of us to not hold all to the rules is the "Joke".

Our hobby depends on all of us speaking up or do something every once in a while to ensure a level playing ground for all. Eliminate the "Bone Heads", don't condemn the class because you don't want to take any action. Once we identify the "Liars", we can publish their names here on IW, and have them wear a Big "C" for Cheater on their T shirts.

If it takes protesting a few engines to weed out those that choose that cheat - so be it. I have a pocket full of $5.00 and don't mind one bit protesting when I believe someone is cheating by modifying a stock motor. If I'm wrong - - - I'll apologize. If I'm right - - I"LL GLOAT !!!! To win a race, or a trophy isn't worth dishonoring one's self. If you want to run a modified engine - take your Classic Thunderboat (CT) hull and race it in Gas Sport classes.

I am very pleased to see the inclusion of the new RCMK and the new 29 Zenoah included in the ScaleThunderboat allowed engines. For myself - I'll run the RCMK with exhaust over the shaft and carb forward. Being an old 1/8th Scale guy - this configuration appeals to me, and makes working on same much easier;.

I have run 1/8th Scale boats pretty much from the conception of the class. I don't believe that I have ever seen one protest of a .67 cu. in. engine in that 30+ years or so. I look forward to some decent competition in the Gas Scale Class, and hope to race CTs as the class defines. The worse day I ever had modeling, is still a quantum leap over my best day at work.

Mikey, - - send me your direct e-mail address again please. For some reason the ones I've tried to send, keep getting kicked back to me. I just returned from California yesterday, saw your request for pics, and have them to send. I sent all of them to Tom when the 1/8th Scale boat was done. CHEERS !!! Bob

I am not protesting just asking if allowing 30cc in this class is wise. I am neither engine expert nor clam to be one. But 8hp in a scale boat seems to me a disaster waiting to happen. I have run scale for a very long time and I do remember a time when they proposed scale going to 80 size engines and that failed horribly. As for me I have planned to use my mod M&D 26 zen and will finish it that way. I think I will win all the time because all the others will be having yard sells.

Mike, to answer your question I have no idea what to do other then keep building and we will see you in May.

 

[Dasboatman]

Hey Don,

I believe allowing the 30 cc engines to allow inclusion of the new engines will be just fine. I don't believe they will be any faster than a good 1/8th Scale nitro boat. Hopefully there will be more of the Gas Scales to race against here in Texas. In the 9 years I've lived here in Houston area,I have seen 1/8th nitro Scales race exactly once.

I don't recall the vote to run .80 cc engines in 1/8th Scale hulls. I've run .60s through 67s for the entire time.

My previous comments was referring to the comment made by Mike Schlindler about Classic Thunderboat class being a joke because of boaters cheating with modified engines. I heard the same line of rationale at the last Lone Star race I went to 3 December. I didn't agree with the thought then, certainly not with it now.

I think most of us would like to see a decent set of rules adopted by both sanctioning activities. Marty and his group have done a fine job to date, and a few little changes along the way will only improve the class. To some, the most expensive engine may be thougt to be the answer. I think that if I start and finish every heat, we can see who has the best package in a Final heat - Heads Up. CHEERS !!! Bob

 

[Gale54]

Hey Bob, it was in the early 90's David Lee and his group was pushing for the scale class allow 80s. It went to a vote I remember filling out my paper ballot to vote against it. I was still living in my fathers house. I am hoping the class takes off I have a lot of time and money already invested in it.I am building plugs and molds for my boat, 1979 Squire Shop & my good friend Chris is building 1979 Circus. I think Marty and the guys out west have been doing a great job too. I love my T boat and the class I have fun running in it. In our club in Madison it is the biggest class and is still growing.

The exhaust can exit right of the strut using a 100 degree header on a Zen or a rear exhaust motor.

Carl has a RCMK K30 rear exhaust motor coming from Gizmomotors. After looking at Mike's motor the coil on the left side of the motor takes up all the room for the pushrod going to the rudder. So I think the best solution would be mounting the motor in the center of the engine bay and mounting the strut on the center of the transom then place the rudder on the right side. I believe the exhaust will have enough room to exit the boat on either side of the strut( I hope). Motor should be here soon, and your cowling fits PERFECT.

I have a thought, just thinking out loud. I am not currently building a gas scale but I plan to in the future. What if instead of calling it gas scale, we introduce a 1/6th scale unlimited class. Back in the day, the big boats where an unlimited class and it made for some interesting power choices. I think it would be pretty cool to have an actual unlimited class in rc boating. Set rules for single shaft, prop driven 1/6th scale boats. And let the power plant be up to the immagination of the builder. 26cc, 30cc, mods, twin, turbine, electric, whatever. Think of the possibilities. I get a stiffy thinking about it. What do you think???

Im sure it would work either way with that motor.

Hey Mike...

i think this is a grand idea

tho gas scale is less than ideal because of the size of the boats... (eff'n wagon to get it to the water? no thx)

the choice of power plant might be irresistible for ppl into "setting a boat up"...lol..im all about setup/testing/learning

Bad idea turbines are not allowed,lets just leave it be! Max 30cc gas only

 

[Bigbird]

Are ya scared. Hehehe

 

[Hydro Junkie]

Consider this, Bigbird, I have a 1/6th scale 7325 sitting in my garage and it's 57" long. If you figure that the full sized boat is 28.5' long, that means any of the modern turbines and boats like the Thriftway Too would be in the 60-64" range. That's getting extremely hard to handle as I found when a friend and I were running his 60" Wildroot "Charlie" on Lake Washington several years ago

 

[Douglas P Shepherd]

1 boat and 5 grand later :wacko: we are at the lake ready to race ! Maybe

 

[Lennard Cuenco]

i agree Doug...

not to mention the lack of interest here in northern california

I am building the Thriftway Too and per the rules it has been reduced down to 59.x inches in compliance
