P-Limited Motors - Im going to jump on the hot seat.

[raptor347]

Hey, are the Typhoon motors easier to find?

Terry,

I'm going way off topic for one post.

The Typhoon motors are very easy to get, www.highendrc.com. Best shipping and customer service short of OSE.

The reason I recommended they be removed from the list is I know what they are capable of. I've run 114mph with a 650-58 series motor on 4 cells. 3400W burst, no problem. I love the reliability, they are every bit as capable as the first generation Neu motors. They are not even close to on par with the rest of the motors being considered.

Now if you're looking for Neu like performance on a budget, there is no better bang for the buck. True P-T motors for $130-$170. An HET 700-83-1445 and a Seaking 180, $270 Q setup that goes very well. Here's the budget option for those who want to get into the open motor classes and not give up performance.

I having a problem seeing how a change from a current P-limited 36mm motor to a 40mm motor would cost anyone $500 to $1000 to change. (or were you saying $500 to $1000 to change ALL 8 to 12 boats?)

The motor itself would cost $80 to $90 and if needing to upgrade from an AQ 60amp, a new SK180 costs $120. So we're at a $200 investment. For those that need to make a change from 0.150 to 0.187 shafts... another $100 tops for stinger or strut (if necessary), stuffing tube, flex and collet. So we at $90 to $200 to $300 investment per boat.
At MI Cup I took my Pursuit with a SK180 and swapped out my AQ2030 for a $75 Leopard 3674 2200kv with an X642 prop. Boat was running just under 55mph and I did okay in P-Offshore. At the back of the pack, but I was happy to be racing at an increased speed.

As far as why have 40mm motors in a limited class??? Because that is basically just open P???
I don't think someone running a $80 to $90 motor on a $120 esc is going to be able to compete with someone having a $250+ Neu motor and $250+ speedo that allows them to prop up much larger and thus go faster.

And the answer there may be to limit both the motor and esc if we go to 40mm motors so that things are affordable with even competition. Another benefit of limiting the esc for limited class is that those still running 0.150 shafts probably wouldn't need to upgrade since there wouldn't be that outrageous of a load increase.

Just limit the motor list to six to nine 40mm choices and cap the esc at 180amp. Any brand esc just not over 180amp. Maybe even a 120 amp limit (which would decrease upgrade expenses by another $35). That way people could bring a new IM31 and only need to change out an $80 motor assuming that ProBoat motor wouldn't be in the list.



Sorry if I'm off base and missing the point here. But it just seems that a continuation down this road of 36mm P-limited is just going to die a slow death and we'll be left with nothing but people that want to put the time and money in to open P.
Yes... there WILL be less of a speed gap between P-Limited and Open P. BUT... costs of motor/esc in P-Limited ($150-$200) will be drastically less then Open P ($500-$600) and we'll hold people's interest in the class because these P-Limited boats won't be running slower then off the shelve stuff coming out.

And if members have a problem with the change, why can't we just expect the local clubs to start running specific spec classes that are necessary in their area? You know much like the expectation that it should be up to local clubs to keep up with the RTR models coming out.
In other words... we are going to loose future new members because we refuse to have a cost effective class that runs as fast as their RTR boat? All over some people wanting to still run outdated slow boats/motors when they could still run those in their local club if they want to.

With a 40mm upgrade and limited esc, we're not stopping people from continuing to run their current boats at their local clubs. But if we don't upgrade we are leading P-Limited to a slow death. Once existing people start switching to Open P, no one will step back to a P-Limited class that was upgraded to late. Thus clubs will start running Open P only, leaving a cost effective class a mere memory.

So in the end, just propose what you're going to propose. Really doesn't matter because this class will be dead in 3 to 5 years with or without these additional 36mm motors. IMO...

I feel your kinda missing the whole other side of the story that we've been talking about all along. What your suggesting (to me...somewhat newbie that belongs to a solely P-Ltd club) equates to huge expenses, in the end, for everyone involved in P-Ltd. I for one definately don't see the limited class 'dying a slow death' as you put it. There is currently WAAAAY too many people involved in this area to consider them/us eventually all go your route.

Darin; I do feel (personally) that the motor list MIGHT be getting too long......but I continue to follow. I'm sure once we find a result, there will be much testing for parity.....

just my thoughts.....

Please keep in mind that we're just bantering about motors. No list has been set. Just trying to flush out options to consider to meet the concerns of those wondering about availability.

[dethow]

Guys, can we PLEASE stop even considering 40mm plus motors? Those of us who REALLY DO know about how this stuff works KNOW that this would blow the current performance parameters of the class completely up. Can you PLEASE just take our word for it?

Okay, I'll shut up about it. After one last point...

I'm sorry I don't understand why everyone should go spend $80-$100 to upgrade to a different 36mm motor that they are just going to burn up trying to get close to 50mph (in mono and cat). When that same amount of money could be spent on a better 40mm motor. Limit the motor list to cheaper/cost effective choices and add a 120amp limit to the esc and we have the future of limited class that has distinctive limiting factors compared to Open-P.

The 40mm motor costs are about the same and a SK120 is actually $2 cheaper then a new AQ60amp (according to OSE prices). Besides the future savings because people are not burning there $hit up as often. This is not a cost issue as far as I'm concerned. The only point to keeping the current limited motors is so that the existing guys with 5 to 10 years experience can continue to run their boats 5 mph faster then newbies because they know how to tune a boat without burning up motors and speedos. Meanwhile we get a new guy on the pond and after the second motor or esc burn-up they just stop showing up because this inexpensive limited class just got costly real fast.

My biggest point of this suggestion is to help stop the amount of motor burn-ups and actually save money for all of us. At our last MMEU race we had two experience guys burn a motor and I burned two. One of mine went because I lowered the strut on my pursuit not understanding that was going to lower the bow and increase load. The other was in my UL-1 because it took a noise dive on take off, stayed open throttle with loose of signal, submarined to the bottom, got the prop wrapped in weeds which burned my motor and broke the flex shaft.

How is the limited class cost effective, if newbies are spending $$$ replacing motors and speedos all the time in an effort to keep up with more experienced guys who also burn stuff up sometimes?

And that is all I'll say on the subject. I guess we'll come back to this in a few more years when people get bored of running slower then RTR boats and sick of spending $$$ burning 36mm motors all the time when they could just go buy a 40mm for the same money.

This is a false predicted result. I race one of these motors in "Open-P"... I can assure you that it's NOT a "limiting factor"...

I'm going to stop discussing larger motors by simply saying this... There is a REASON why Nitro doesn't allow 7.5cc (.45) motors in the 3.5cc (.21) class...

There is already a class for these "Open" sized motors.

Dave, it's a tremendous expense for some. I have 8 to 12 boats to retool if I want to keep up with the 40mm guys. To make it worse, I would have at least 5 boats that can't run that much power. So I would have to start over on those. It's not all about the motor speedo "replacement" cost. Transfer that expense into say a club with 25 or 30 racers whose boats are not going to work on that much go juice. Suddenly a club is looking to rebuild (conservative) 40 boats to deal with more power.

I'll do what ever the rules say but there is no reason in my opinion to flush the setups of the most populated classes in FE history.

Also, burning motor after motor shouldn't happen. There's something wrong usually. Either a motor build glitch or a boat build glitch. This is where a club comes in to look at a setup to try and figure it. 3 of us looked at Benjos boat before we figured that sucker out.

[Darin Jordan]

To make it worse, I would have at least 5 boats that can't run that much power.

And, NOT RUNNING that much power is exactly the point of P-Limited. Always has been.

Hey, this discussion has taken on a brushed vs brushless quality.

If we do this right (like using the motors on the currently drafted motor list... TP, Leopard, TFL or ???)... Then you'll continue to use them in some boats while you slowly replace them in others.

I would have NO ISSUES putting the PB Dynamite 1500KV up against any of these, in the right application.

Well, I could but they would explode on re-entry into earths atmosphere.

Somewhere in Shooters' New P sport thread there is a picture of what happens when you just throw more ponies in your paper machete LSH boat.

[T.S.Davis]

Darin, I meant that based on Dave's notion that we should just replace 36mm with 40mm since the market is creep'n that way.

You and I are on the "keep our brushed motors" er............36mm crap side this time.

What do I do with my old brushed setups if we go BL?
What do I do with my Nicd setups if we allow Nimh?
What do I do with my 700 motors if LSH goes to P limited?
What do I do with my Nimh setups if we all go LiPo?
What do I do with my 36mm boats if we go 40mm?

Never really ends with FE. I'm not saying we ditch our 36mm stuff but I am saying it's happened to us umpteen times. What Dave suggested isn't that nutty.

[dethow]

What Dave suggested isn't that nutty.

Thank you, Terry... I was feeling totally beat down.

I really do get all the points, but what you are eluding to is correct. Where would we be if we stopped progress...???

With a switch to 40mm we'd probably have more blow overs and less burnt motors/speedos until guys actually learn to bring their prop size down a little and/or learn how to self limit their throttle finger. In which case either method would result in far less burn-ups in efforts to push the P boats to their limits.

I feel new people would much prefer a chance at winning if they can learn how to not be up side down... over a chance of winning if they can spend the $$$ burning stuff up learning how to tune a boat.

Ummm... learn how to drive, or learn how to tune a boat? Learning to drive better costs nothing, while learning to build/tune a boat can cost a lot.

Open-P is the class for tuning, not P-Limited. The way things are P-Limited takes more tuning then open. Makes no sense to me.

[Darin Jordan]

What Dave suggested isn't that nutty.

See any Brushed Motors or NiMH these days?

36mm x 60mm motors are a standard size across the industry. We're not talking about a dieing technology here. RTRs don't define racing. Their power systems were convenient at the time.

We now have the formula. I say let's keep it.

You know me, I'm all about RTR boats (You won't BELIEVE what Pro Boat sent me THIS week!! ), but their inclusion in the race day needs to be handled at the club level.

Imagine, if you will, if we had pushed to have a NATIONAL class for Spec-SV27? Where would that be today??
