Servo sizes for 40 tunnels and bigger

[rumrunner]

Ha guys I've ever flipped my hornet with the Mac 84 , and it's on a 45 lawless and it pulls a full x460 , ive broke one flex ,it's problem was it ate the lower unit up , in that I run two of the standard airtronics servo that Otto mentioned earlier ,

Gabe and mic it hurt's that you guy's have no faith in me not to flip this boat. (LOL) my record proceeds me

 

[topfuel443]

You'll flip it Shane, but it will be SPECTACULAR.

36"Length + Tunnel Boat + CMB 101outoard = Shanes next headache

Kidding aside man, it should turn out to be a rocket. (literally?)

 

[rumrunner]

Guys i'am not sure now what should I use one 1/4 scale hitec hs5755 mg or two hs5755 mg or one of those servo city geared servo? I just want it to be realible

Shane

 

[julianconde]

use 2 of them

 

[rumrunner]

use 2 of them

That's what I was thinking ,but the gear servo form servo city has 1715 ounces of torque and .72 sec. And like gabe said it just real strong and beefy ,do you know if these gear servo's are realible ?

Thanks

 

[julianconde]

well with everything is trial and error i have not had any issues with the gears at all. it all depends on what you wanna do and how much money you want to spend i think both set ups will work just fine

Use the same setup that you have in your Hornet with the .84. If it hasn't failed yet then it should be fine for the bigger motor too. If it's the lower like Otto's then you actually might have less resistance against the servos than the lawless on the .84.

Thanks, it runs two standard size airtronics

Ok it's not a45 lower and it's not a gas, it a custom go devil lower like otto's 40 boat , it use 1/4 flex's,Mic are you saying the servo city geared servo's are to slow, when I use 2 servo's I never link them one to one arm one to the other

I hate to break the news to you, but that's NOT an outboard!!!!! Outboards are meant to be mounted OUTBOARD, and not INBOARD on a turntable. It should be mounted on the transom of the boat and fully visible. Outboards bring a dimension of issues such as COG that takes a lot of time to figure out. If you are building it to run in a Hydro Class, that's great, but if you are building it to run in an outboard class, get a lower unit from K&B, Lawless, Hyper Performance, or OS, and figure out how to get it setup, consistent, and competetive, like the rest of us that love the outboard class. You could also petition the IMPBA and NAMBA to maybe create a new class, like maybe an inboard/outboard class, but what you are building has no place running with outboards.........sorry........

 

[rumrunner]

Sorry but i'am not the first one to do this , i'am just doing what some else has done before me, as for not following rules I think your

Wrong there, if John Otto runs this in setup in 40 tunnel and open tunnel and there's other that run it gas tunnels, I would think Otto knows the rules, right know I run a Mac 84 on a lawless , this is a E/F class tunnel at the world tunnel champs , there's not al lot of people that run in this class but it still is a class ,so I can run it .

No hard feelings

Shane,

Just because others may be doing it doesn't make it correct. This isn't about feelings and it's not personal, it's also not right. If you can send me a picture of a full size tunnel that runs an inboardnengine on a turntable, in the outboard tunnel class legally, then I will stand corrected. Think about it, where does the term outboard come from? If you really consider the class of boats the outboard tunnels represent, and not make this personal, you will agree. Just go and pick up a lower like the rest of us, hang it off of the transom as the class represents, and let's run outboard tunnels......... If you want to make it an inboard, just run it with the hydros. If you want to develope a competitive OUTBOARD tunnel edge, do it the old fashioned way, by hours of testing different hulls, props, engine/pipe setups, COG, and tilt, not by running an INBOARD setup that automatically gives you a technical edge, not intended for this class.........

 

[Kris Flynn]

I think Ron is scared to race you Shane. lol

 

[rumrunner]

I know it's not personal, and the only thing I run is tunnels ,so I understand what your saying, but this is the old fashion way of thinking which is the way I thought till I saw one run ,there will always be people doing things different then all the rest of us , boats have changed , motors have changed ,I just think of this as change

 

[rumrunner]

I think Ron is scared to race you Shane. lol

Now that's funny

you coming to the tunnel champs this year

 

[RonShaw]

Shane,

I am all about change, but we need to stay within the basics. I know I have been away for a while, and believe me, it's great to be back.... I have always been partial to tunnels, that is why I spoke up on this. I want us to keep the integrity of the class intact, and running inboards against outboards doesn't do that. Yes, the out drive turns with the motor, but the reality of it is, it's not an outboard, period. My reason for speaking up wasn't about you at all, so I am glad you are not taking this personal. I saw John's boat in Charleston, and I said right then to a couple of people, that is not an outboard, and should not be allowed. I have known John for many years, used to race against him and consider him a friend. This isn't personal against him either. I don't blame him for trying, just can't believe no one else has said anything. I just dont want to see this get out of control, and with you building one tells me there are probably more.

This to me is just like trying to run a hull with multiple wetted surfaces, in the mono class. Let some one try that and I can assure you, it will be squashed right away by many of the mono guys, including the Mono Technical Director John Finch. The IMPBA Hydro, (would include outboards), and Tecthical Director positions are open. John Equi used to be the National Technical Committee Director and I am sure if he was still in that position, he would agree that this design is not an outboard. In my discussions with others, it seems as though this position has been weak since he took on other roles within the IMPBA. With all of this being said, and until these positions are filled, I think we should all try our best to uphold the integrity of each of the classes and the types of hulls and designs they were intended to be, don't you? I'm not saying you shouldnt build whatever boat you want to build. Just keep in mind the rules and intent associated with the classes where you intend to compete. Get your competitive edge by hard work and skill, not by blatantly ignoring the rules and intent of the classes..........

 

[topfuel443]

Otto talked to me about his design before he built the boat a couple years ago to be sure it would be legal. It is TOTALLY legal from a rule book stand point, and thats the bottom line as to why it is legal to run with us. I understand your point Ron, and agree with much of it from a historical standpoint. However, its legal as the rules are written. John is also not the first to do this either, it was done a few years before out west for a straightaway outboard. Is it pushing the rules? Sure. but thats what happens with any level of competition.

If someone isnt happy with the way the rules are written that allow such different designs to be legal, you have every right to propose an amendment to the rule book to re-word it to disallow the "out of the box thinking".

The words 'intention of the class" has ignited much bickering in year past (mostly with the Sport tunnel class). Its impossile to argue with someones perception, especially when the rule book leaves so many things wide open.

I take it as a challenge - to step up, even with the more conventional outboard set-up. Lets be honest, Otto would be a SUPER competitive person, even if he were racing a 2x4.

Thanks for keeping it civil guys.

Gabe,

I'm glad everyone is keeping it civil as well. No need to put Otto on a mountain...... He is an awesome competitor no doubt. Doesn't matter if he can beat someone with a 2x4 as long as it has an outboard engine and not an inboard. Please don't make this about him because it's not, it's about what's right. I have spoken with several outboard people and they ALL agree. I guess me coming back after being away and seeing it made it blatently obvious to me. I consider John Finch one of the best mono racers ever, but just because he is John Finch, I don't see him expecting other fellow boaters to allow him to break obvious rules. Its well known by now, (.... ), that I consider Tommy Lee another one of the best outboard racers ever, and when he experimented with inboards on outboard tunnels, he raced them in the inboard hydro class. Again, I think the world of John and this is NOT about him. I am not trying to squash "out of the box thinking", just "out of the box thinking" that breaks the rules.

My point, it automatically breaks the very first rule that does not need to explained in the rule book, it is NOT an outboard. It is an INBOARD. Just because it meets the rule of the drive shaft turning with the engine, it still breaks the known rule of NOT being an Outboard. If it is not fully visable and hanging off the transom of the boat, it is NOT an outboard. If we allow these "known" rules to be broken, you are opening up every class for the same to happen. If the rule book needs clarification to point out the most obvious, then we need to do just that. But obvious rules should not need to be explained and this is where the technical committees come into play so they can make these rulings and keep personal feelings out. If not, inboards are going to continue to show up at the races and bleed over to other classes as well, such as outboard hydros. If you put the respect we all share for Otto aside, not make it about him, and think about the hobby we all enjoy, you being one of the most competitive true outboard tunnel racers I have met since returning, and the fact that although you are not officially in the technical area of the IMPBA but you are the Outboard Director, you have to agree.........

 

[rumrunner]

Thanks for clearing that up

 

[RonShaw]

Thanks for clearing that up

Shane,

It's not really cleared up, just out there for opinions such as Gabe's. Since you are in the process of building one of these, would you start a thread on this discussion as many outboard racers will probably need to join this conversation? Not many people are going to see this discussion here....

 

[moparbarn]

WHEW, where to start, where to go????????? i'm as much of an outboard purist as anyone, rc or full scale. i can wholeheartedly agree with ron's opinions, it does not meet the "CLASSICAL" notion of an outboard. but, without thinking outside of the box, this hobby will stagnate. if the engine, lower, flex, prop & skeg all turn as a unit, it is technically & LEGALLY an outboard, as the current rules are written. ron, just keep doing what you're doing, your boats are fast & handle well B) . make them beat you, it will take some doin', imho!! like terry keeley says "if you do what you have always done, you will get what you always got", or something close to that . nobody's asking you to like it ron, or run it. but, as long as it's legal, you will have to race against it. i'm not trying to pick as side here, hell i don't really like a lawless or rek lower, just because they cant the engine foward. looks nothing like a "real" outboard, they all stand up straight, & my ob tunnel engines will also . but this hobby needs all the foward, out of the box thinking it can get, as long as the rules are followed & enforced. see ya'll at the pond .
