Castle HV Hydra, but where is the car version!!!!

To be honest, that is not a very wise way to do business. I would never allow a employee to say anything close to that if I owned Castle.

Personally I like the fact that Joe acknowledges that we are going to try to use stuff out of spec and tries to help us with it anyhow. I hate calling up companies CS and ask "if I did this, how would it turn out?" and get "it is not covered under warranty" as the only reply...At least Joe says "well if you do that I'd do this to prevent this, but just so you know, if you do blow it its not under warranty when being ran like that."

I do, however, find it true that a very small, select group of the RC population, basically the users of this forum (which is very small even in comparison to just the electric RC population, in fact), are going to run anything more than 6S on a very consistent basis. And I still haven't even ventured past running 4S on any of my vehicles.

BUT - and a huge BUT here. I think at the very least CC should take Pheonix HV controller, give it some car programming, and up the current rating to at least 150amps, and make it available. It wouldn't hard to do (they just have to wire more fets in to add amp rating - its basically what they did to make the 110 in the first place). The only hitch they should imply is that mechanical brakes are REQUIRED. To be safe they could call it a 10S max ESC and that would be fine too.

Hey, at least they are bringing out HV controllers. The boat guys are crazy, if you look around you will see that they are running the huge lehner and neu motors on ridiculous voltages in tiny boats! A guy did 140 in a park pond with an outrigger for petes sake. I have played with the non-HV hydra and it is a nice controller, can handle 6s and the water cooling does help the heat issues. My 45 mph supervee running lipo and the stock esc/motor does not even get warm. I think that the car controllers are the most difficult to get right due to the massive current spikes and partial throttle running. Air cooling tends to be much less efficent than water cooling. Imagine how cool a car esc would run with a constant flow of 60f air over it. Larger capps seem to help with the heat issue due to partial load, but even they heat up eventually. And we have to remember that not everyone is crazy enought to buy 10s worth of lipos to test out a theory!

I've been running HV for a while now. My first HV (Not like HV to current standards) was 12 cells NiCd with my old Aveox system. Most of my HV set up (When I'm not trying to break 100MPH LOL) runs cool due to less AMPs required for an HV system to run. I will put together my HV buggy and run a SPIN 75. I will not use my Jazz 55 mainly because a member have posted great numbers from it in another thread.
