Traxxas Titan

Keith, what's the turbo avatar about?

My last avatar was of a boat that I no longer have, so I felt it fitting to change it.

I had to do a turbo swap in my daily driver after the center section went on me and bought that precision turbo in the pic. I love the look of a billet compressor wheel when its brand new so I had to take a pic...just decided to use it as an avatar until I get pics of the boat I am building now because I think it looks cool.

Even though I have hard facts (personal experiences, not data) about this situation (both partial throttle and reverse) I don't think I'll be able to change anyones minds or beliefs. As far as this boat goes. I hope it lives up to the hype.

I dont buy into that "50% power makes more heat" stuff. I have heard the theories and they are riddled with holes. It just doesnt make sense and I have yet to see real evidence of this. I do, however, beleive that running at part throttle can require just as much dissapation efficiency as full throttle, meaning that you cant "under esc" a setup and just run it at part throttle.
Twisting on the cable back and forth over time is obviously going to have an effect regardless of how much power is replied in reverse. 15% power is better than 100%, but I would still disable it personally.
Besides, reverse is useless in FE boats (some uses in scale boats maybe...). All it does is suck the back of the boat under water and push water over the transom which is undoubtabley going to leak into a boat that uses body clips to hold the hatch on.
If you need reverse on your boat to maneuver it where you need it to go, good luck running 50mph

No doubt

[Brushless55]

I'm not going to keep bickering about what the wrong direction of spinning a flex cable will do.
If your prop is loaded with weeds, you should be more worried about the amps that will be reaking havoc on your gear anyhow.

The esc isn't going to do me any good in ANY of the modes anyhow. Unless it has a hovercraft, or snow mode.
When is the release again?
You really are going to need a "Snowride."

I'm a little slow at times, but I get it!

It's not a conspiracy. You don't have to "believe", you have to observe controlled facts. Hopefully this reasonable conclusion based on the observation of controlled facts makes sense:

Bottom line: The ESC measured in this case operated hotter at half throttle than full.

I have observed controlled facts...I have personally done the same test and found results not at all consistant with with what you linked. The only difference is I did not use a controlled power supply, since I dont have any RCs that will maintain a constant voltage regardless of load.

The realitiy is that testing one ESC in one scenario is not going to provide a rule to all of them regardless of what your findings are. Tests like this one are good, but hardly something to jump to conclusions about as I said there are holes in the test protocol. I assure you the same test could be done with different results realized when a couple different variables are presented.

Thanks for the link... interesting read. Makes me want to do more testing

Keith there is an electrical engineer on the forum that at one time made esc's for a living. He has also backup all the data.

A couple of other points,
1. I think this is all useless banter until the boat hits the market.

2. By the time the Spartan does come out, Delta Force will be out with its Almost ready to Run Cyber Storm 33.

Guys, Get Ready ! the DF Cyberstorm ARTR is going to be the REAL DEAL!!

So what may I ask does this have to do with the Spartan? No wonder things get confusing around here.

Exactly.
