    What can I use as a substitute for MLV?

    In general that is a safe assumption. Not saying there isn't something else, but good luck actually getting information out of the company who supplies it.

    Welcome to the IHoP v.2

    Sounds like you may really enjoy his music. Not his music. Long story short, at the time, had just started dating simply one of the most staggeringly attractive woman I have ever met, off the charts and Neal you have a great idea of what I mean. Anyway, she and her best friend wanted me and the other BF to come to his concert. We couldn't, we had a tournament we were long since apart of we had to be in. The good thing was that we could drive the girls on our way, drop them off at the concert a little early, play in the tournament, and pick them up on the way back. Well, we drop them off, and later that night as we proceed to drive back to what was at the time the MCI Center in DC, we get a text message saying that we didn't need to pick them up. So obviously we ask why. The reply was they were on Kenny Chesney's bus enroute to the next show. So.... you can see why it is not a positive thing for me. If it was someone like Timberlake or Maher, I could understand... I never would have guessed that he did stuff like that. Hate to be this guy, but why do you think musicians are musicians? Ladies first, money later. My prom date ended up on the Slayer bus and got slayed. My current wife, the Metallica bus but she was too prude. Her friends not so much.

    Beware, it isn't just the foil. The Butyl formulation and adhesive are HUGE!

    This is my third Nitro truck btw. Just time to make things easier.

    Welcome to the IHoP v.2

    Faster, easier, less maintenance, yada yada yada. I also want to be able to easily adapt it power wise to let my kids drive. Way easier with a battery powered unit. Add that to how often I end up upside down which isn't super for a 2stroke. At this point in time the only reason to buy Nitro is because it is fucking cool or you like huffing the smell of it

    Revo BL power

    Welcome to the IHoP v.2

    And the Revo If you want to see in air control go to 1:36. The buggy video doesn't show this, but they are even better

    I only want a basher and will never race, but the control you have of an 1/8th scale buggy in the air is awesome.

    Welcome to the IHoP v.2

    Then the question becomes do I buy an E-Revo, a Savage Flux or an 1/8 scale buggy and convert it to a truggy.

    And exactly why I have no respect for Ant. You've seen my public discussions but it all stemmed from a private discussion where I offered to do some unbiased tests. Don was all for it and we discussed techniques for a while. The Anthole understood nothing and acted like a dipshit during the whole discussion. Don & I decided not to do it in the end due to the fact that the variables in the test article (not the applied damping) and overall fixturing concerns would create confusion in reading the test results. This is something the OE's battle everyday and don't always understand and why 3M contracted me to help in the first place.

    I'd still take care of rattles but until tire noise or some other aspect is of bother a generic cover all solution I would not employ.

    If you want to spend some time understanding things read Wiki on: Damping Modal Analysis Transfer Path Analysis There are a ton of other topics as well, but this is a start. We own the most advanced test lab for acoustic damping & modal analysis in the world. If I can answer other questions let me know. The OE's all come to me for help regularly. I can't write a dissertation on here due to NDA's but can surely share how to help and understand needs in your situation.

    Do NOT mix up a deadener and a barrier. Creating a sound barrier requires one and only one thing. Mass. The lighter the weight the worse the barrier. /discussion Deadener is a completely different beast. The goal with a deadener is to change the damping and modal frequency response of the target panel. While you can do this with mass, it is a really shitty way to do the job. It would be akin to making your car heavier instead of using shock absorbers. While of course this will indeed stop the car from bouncing around, it is a rather shitty way to do it and will create a terrible riding vehicle. In the case of a panel, something similar will occur as you will change the frequency of the resonance and affect the damping but not in a way that is what anyone would call successful. Instead using a constrained layer you can constrain (ie add damping) the resonance and convert the energy into heat. This is why a viscoelastic material is needed along with STRONG adhesive and a reasonably robust (ie thick) aluminum layer. Of course it is easy to go overboard on anyone of the layers and add no benefit. As for the sound absorber, this normally requires thickness. This works akin to the deadener but for air. Basically we have to convert acoustic energy into heat. You've probably seen acoustic traps in offices and other spaces. These are normally very thick to even be able to "absorb" higher frequencies. In a car this is impossible. The clever engineers at 3M though engineered a technique of taking a long drawn fiber that forces the sound to think it is traveling through a much thicker material than it is. Acoustic Thinsulate is extremely effective when placed inside pillars and other areas where sound is transmitted through. OE's spend TONS of $$ on doing Acoustic Transfer Path analysis to determine what is coupled where, how things propagate and low cost low weight mechanisms to improve them. I've had the engineering team at 3M give me thinsulate for my cars since the mid-90's. Of course I can cheat and mimic tests done by the OE's to optimize, but there are some great locations to use this product. For what you've described and needed so far though this is not where I'd start.

    I RC when time permits which isn't very often. I just gave my whirlybird to a friend as I wanted to see it being used. Still have my 4WD truck. What was the question again?I am done buying nitro methane. I have a Nitro Revo. Question is spend the $$ to convert it to electric or buy and electric. BL of course. Net $$ is about the same which has me leaning towards selling and buying since it then involves no time.

    Randomly and interlocked. Something like this is close to ideal: where none of the spaces are the same. Obviously you won't go that far, but the idea holds.I have to ask.....what is the purpose of bracing like this?This is not something I am at all familiar with.JJ - that is bracing. How else would you do it?The goal of bracing is always the same. Too reduce ANY modal behavior in the acoustic or vibration space that can color sound. A honeycomb structure like the above helps not only mechanically but also acoustically. Obviously at the wavelengths of subs and not mids the structures don't need to be as tiny. Honestly the enclosures I have build have only been for vehicles and usually the port and overall box design braced the box well. I have never built anything for inside the house. J That changes nothing.

    Pfft. Can't find the right one as this is team blueberry, but this is a trailer

    It is SO EASY on my sled. Everything else I've ever ridden is super hard in comparison. I do stand, but that is because you don't really sit on my sled. Doing a Carl's cut on my ski's would help further. To sidehill I don't need to turn or pull, just shift my weight to one foot. If you actually put the wrong foot forward it does it pretty much on its own. Need to counter steer to turn of course
  20. There are plenty of other ways to spend money to give you an edge. Way more effective. Attacking the sonic space is the best method. That isn't cheap though either. I have a few engineers working for me that basically just do acoustic and damping optimization on car bodies all day.

    Anyone R/C here? I am thinking of either selling my Nitro Revo and getting a waterproof brushless or converting it. Cost will be similar. Also contemplating the Savage Flux and Thunder Tiger mt4g3 but that is a different question.

    It was for the first 200 miles. Now I have a ghost.
  23. I'm right, it just boils down to price? Now what about this, Even if it were applied, would there be any appreciable benefits? Extending the thermal rating of the driver. So in competitions where this would be legal and you are limited in cone size theoretically you could then worry about the mechanics of the driver and not the thermal rating. Obviously a driver would need to be designed for the cooling for it to be effective.

    And FUCK me. My sled rusn GREAT on one cylinder. New coil, plugs, checked wiring and still SO FUN to find electrical faults.
