What's the price for ?

Well, DE has the "Anyvolt" micro, which steps up or down as needed. Probably not enough current handling capability as-is, but they could beef it up if the market was there. From what I can tell, it is meant to be a high efficiency version of the linear regulator LM317T with similar specs, except it has the added bonus of stepping up.

Some of the switching regulators that I'm planning on using for a ESC I have plans for can provide plenty of current. This is one of the ideas I sent to a couple of people, one here in the US and another in Europe. None of them makes anything for the hobby so this will be their first project. The only thing, it'll be focused more on a higher voltage set up and plans for a 20S ESC is in there.

Most 1s racers use the Novak Smart boost 1 lipo module.

Making a BEC really isn't that hard, even an HV one. It's making one that can handle the potentially huge braking spikes and doing something to protect the components attached to it if it fails.

That's why I've contacted 2 of the best in the brushless business. One has a few patents for various designs and the other has a product that will take sometime for anyone to match. None though like I mentioned have done anything for our Hobby. At the moment we're just going back and forth with ideas.

From what I have seen with pretty much ANY competitive sport where an organization strives to level the playing field is that people find ways to unlevel it again. This 1s lipo rule seems to me to be one of those. It's a lot like the old car audio competition days where people used "cheater" amps designed to run down to 1/2 ohm loads. Yeah, the amp may be rated at 20w into 4 ohms, but run it down to 1/2 ohm and you get 8x the power. Really, the only way to make things fair for everyone and not rely on how much cash you can throw at it would be to specify the exact battery, ESC, motor, suspension, etc to use. Basically, give everyone carbon copies of the same car and the only thing you can do it tweak the suspension for handling. That's it. What's next; the 1 NiMH cell class?

I still have my Orion and Memphins 25W x 2 cheating amps. I ran the Orion all the way down to 1/4 ohm and yes it was sick.

Like I said before, if ROAR wants to keep everything fairly cheap, they should handout esc/motor and now packs lol.

The part I put in bold is where the oval pan car racers are really hypocrites. They want the ESC, motor, and battery to be equal but the chassis/suspension open.

The 1S rule has nothing to do with leveling the playing field. It was instituted so that carpet racers can get the benefits of Lipo (over NiMH) without so much voltage that the cars are too fast for the majority to drive. The 2S LiPos make the cars too fast with the available motors. Changing just the battery voltage, was the simplest thing to do.

You guys talk about power motor outputs of 1000 or 1500 watts for your RC Monsters. Running at full throttle the whole race, a 1/10th pan car with a 13.5 motor runs on around 75 watts input to the motor, maybe 65 watts or less after you factor in motor efficiency.

Handouts only work at big races where the entry fees can cover the costs. Handouts are not feasible for club races.
