re: JD moving strut on Sport 20 to transom

No, I race under NAMBA's Sport 20 guidelines.

I don't buy that at all. The hull definitions between IMPBA and NAMBA are miles apart. I run sport hydros in NAMBA that would get DQed in IMPBA, some are modeled after UL's like the Pocket Mechanic and baby Bud.

And when establishing a BRAND NEW CLASS, that was already defined by NAMBA, what did IMPBA do? Did they look for ways to bring the two organizations closer? Did they pattern the rules for the new class off of the NAMBA rules to encourage people to build boats that could run in either organization? NOPE, the decision was to create yet another incompatible class.

Sorry, didn't know NAMBA raced sport 20. Regardless of the ruling you still have the option of putting your strut under the boat if you race both Orgs. But now racers will have the OPTION of mounting the strut on the transom and could lead to the rule spreading to sport 40 and NAMBA.

I've got boats set up both ways and the only advantage between the two is ease of setup. I belive once people try mounting the strut on the transom they will prefer it over under the strut on a sport hydro.

I can recall only one instance in recent times that NAMBA changed something that fell in line with IMPBA & that was expanding the X class (F class in IMPBA) to 30cc & that was NOT because of what IMPBA was doing. I seriously doubt that NAMBA will ever change a rule just to follow suit of IMPBA. This is another example of what's good for the few being more important to them than what's good for the many. Not to mention our international friends who come over here to race. Like I said before, once again we drive that wedge further in between the two groups instead of trying to grow stronger as a whole. It goes way beyond where you stick your strut. <_<

I know how some of you feel,,The strut placement in the two places shouldn't make any diff,,as a matter of

fact a NAMBA Dist 8 "Hall of Famer" tested both arrangements and found that it didn't make a difference :blink: :blink: So why does it have to be so "concrete"in the end.

In NAMBA also you can't have your pipe exposed,,Why? Probably in an effort to keep some amount

of cowl in place,,I don't know. I think Phil T's statement was right on, "some people think scale, ain't

scale enough and sport boats aren't scale enough either.

The cool part is that the club I belong to will let you run just about anything you bring,,they're glad to

have the all the boaters they can get.

Personally I like the look of a sport 20 with it's pipe stickin' out, it reminds me of the fact that we're

actually running models :lol:

Hi Don,

I seriously doubt that NAMBA will ever change a rule just to follow suit of IMPBA.

I don't belive it's a NAMBA/IMPBA thing, I think it's a member thing. If people like it they can put it to vote. If they NEVER get a chance to try it how will they know if it's a good or bad idea. You want to race both Orgs put the strut under the boat, EVERYONE HAS A CHOICE. Is that such a bad thing?

Paul.

It was the members vote that chose the rule.

Bill, I'm curious. What is the position of the leaders in IMPBA about seeking commonality with NAMBA? Do you and others think this is a good thing? If so, are there active projects trying to make it happen? When opportunities come up to try to align classes do the leaders advocate doing so? Are there efforts to steer the organization in this direction, or is it just wandering whatever way the small number of members who actually care to vote take it?

Edit: And if any of the leaders of NAMBA are reading this, what are your thoughts on this?

 

[Jerry Dunlap]

re: commonality with NAMBA

One thing that appears to have support is replacing the alphabet for engine size with numbers. This change has been discussed previously on IW.

I raced at both the NAMBA and IMPBA national events in July and I don't think there's really all that much of a difference in the nitro racing classes. The most noticable difference was the starting procedure - 1/2 course mill for NAMBA, full course mill for IMPBA. Personally, I like the full course mill. NAMBA's rule book does allow for a full course mill. The mill pattern is at the descretion of the Contest Director.

Nothing like getting completely away from the original topic of this post.

[piper_chuck]

Jerry, you're right, this is a bit away from the original topic. I started a new thread in the general forum and have responded to your observations there.

 

[Don Ferrette]

It was the members vote that chose the rule.

............ and it was by such an overwhelming majority.

But Bill is right, it just a damn shame how pathetic the vote turn out typically is regardless of what is being voted on. <_<

With our electoral college style of voting, who knows whether it was a majority or minority?

Will the results in the roostertail show the district vote totals? those 15 votes were the directors votes not the whole membership.

Why all the whinning and worry?

Im sure anyone that wants to run Namba will leave his boat strut setup under the hull.

Mark A already reported no advantage to setting a sport boat up strut on transom.

The option passed because there was enough intrest in setting up the boats that way, maybe because it makes it easier or maybe they think it will be faster.

It just amazes me that anytime a rule is brought out like this it is thought to be a must do from now on.

 

[Ron Olson]

Phil hit it on the head, if you already have a Sport 20 and don't want to fill and drill, leave it where it is, no one is telling you that it has to be moved. Now you have the option to hang it off your transom if you wish.

To those saying that it will make adjustments easier, how? In my Sport 40, there is only one bolt to loosen to change the height and angle.

I agree with Chuck also, I don't like and never will the Electoral College style of tabulating votes.

 

[Chris Thomas]

There is only one advantage to mounting the strut on the transom. It makes the boat longer without adding hull. It changes the lever of the boat. And turning radius. And weight distribution. And CG. And....well the percentage it changes the boat depends on the hull design itself. And this option may be negligible, it is a small percentage of how close the the hull is to being "dialed in". Probability being : un-noticeable......

Hey Guys,

To those saying that it will make adjustments easier, how? In my Sport 40, there is only one bolt to loosen to change the height and angle.

Ron, belive me that the adjustment is much faster and WAY more conveniant to do when the strut is on the transom. Every sport boat I have is built that way, the only thing built thru-hull is my 1/8th. Building the boat is also a joy when you don't have to worry about cutting the slot in the bottom of the boat.

There is only one advantage to mounting the strut on the transom. It makes the boat longer without adding hull.

If you need to mount the strut 2 or 3 inches off the back of the boat then you've got the wrong boat. ALL of my sport hydros have the strut tight on the transom, the difference between under the hull or on the transom is no more than an inch. I've tried running extended struts and they upset the boats handling. Like I've mentioned, I have a bunch of experiance running hydros like this (well over 50 boats built) so the advantage is in adjustment and assembly.

This is for all the guys that like to run the sport class. We all know setting up a sport boat isnt easy and can be frustrating at times, you know (fall off pipe, the transum rides heavy) tryin to find the right strut depth and angle, ( .P.S. after the correct needle setting and pipe length for sake of argument.)but for me,,I find that this is challanging in setting up a sport ,with the strut under the transum. which in a way defines the true nature of the word "SPORT" and seperating it from "riggers" and all the other classes. dont get me wrong a strut off the back of the transum only an inch farther back is still keepin in the realm of sport with no extra advantage, is just find with me! , (just easier access for strut adjustment). But you put a 3inch strut bracket, with a strut with a 1/2inch protrusion on the transum and your talkin about 3 1/2inch of strut stickin out like a rigger. giving a little extra lift with less strut angle and less effort ,just takes all the "SPORT"!!! out of it. :::::::::: but on a nother note, im almost done with the plug for a new sport 20 hull its 30 inch long, 16inch wide,the sponson ride pads are 13inch wide for more ride stance to keep it more stable in the corners, the engine bay is only 4inch wide, sorry for that, for those who run F.E. my be you can make it fit ???.it should be out before april before race season. just to give you an idea of what it looks like.its looks like a supersport 45, just smaller. BUT NOT A COPY!!!.I wouldnt do that to phil or anyone else.

[Paul Pachmayer]

Hi Scott,

the engine bay is only 4inch wide, sorry for that, for those who run F.E.

LOL, My 1/8th scale only has a 4 inch wide tub, on a sport 20 that's plenty of room for an FE boat. Your biggest challenge would be to keep the weight to no more than 2 pounds bare.

Paul.
