does raising the punch% decrease mid and top end speed?

[blueb8llz]

i have mine set at 70% punch which is basically 30% power for the punch...and i really hope since i have it at so low power, it doesnt mess with my mid and top end...does it? so when does it actaully give it 100% power...right after the initial squeeze on the trigger?

reason why i have it set so low is because i remember when i just ran stock 7 cells, the truck would haul a%# from the stand still, but now after i went mmm/7xl, the thing flys mid and top end, but doesnt even compare with the low end it had running stock. im thinking of changing the punch to 80% so that i can push the throttle almost fully without it wheelieing so it can take off like it used to but even then i might not because its giving it so little power now. ill have to go try when i get my replacement fan from CC.
for the meantime, does anyone run their punch% as high as i do??? from what i hear, alot of people run at 30%, if i did that with mine, my truck would be slow as a turtle taking cus if i give it any more gas itll flip.
is my batteries just that good? i run neu energy lipos 2x2s.

Punch control on the Mamba line of controllers is basically a spool up timer. The higher the setting, the longer it will take the motor to spool up to its top speed. It wont spin any slower, it will just take longer to get there.

You are still going to need to use some throttle control when driving. punch control is one thing for taking away the hard edge of the power, but if you use it to totally remove any chance of flipping the truck, you will be taking away the acceleration rate throuout the whole curve. Ya just gotta learn to drive it.

As far as what others set theirs at is really irelevant. Every motor, battery, and gearing combo is going to change how the punch controll setting feels. Just find the setting that feels good to you and go with it.

In my track buggy I actually run 70% because it gives me better controll and faster for consitent lap times, but in my bashers I run wide open 0% punch control. Just controll your finger.

I read somewhere that the punch control basically affects the rate of change of the throttle position inside the esc, so even if you squeeze the trigger to full, it makes it think your slowly applying the throttle. Doesnt change how much power there is.

that does sound like what the punch control is doing sammus. it doesnt really seem like i lose much or any power when i have my punch % higher, i just need to press further down on the trigger like sammus is saying.
but jhautz, you say i lose acceleration with higher punch, i actaully gain acceleration because even tho its sending less punch, i just pull the trigger more, but when i have the percentage at like 30%, yes it sends more power, but itll just wheelie causing truck to slow down or lose control, even when i do throttle control , yea i can have my truck take off without wheelieing, but its going real slow taking off any more push on the throttle, and itll just wheelie, nuthing else i can do right? so people keep telling me throttle control but i can do that..thats no problem but the car will just take off too slow. am i doing something wrong here. all help will be muuuch appreicated!

Not only does punch control allow for more controlled takeoffs, it can actually help battery life by not pulling quite so much current.

What samus said and what I said are the same thing. It just controls how quickly the motor can spin up to speed and therefor controling the power at take off. It does however control the acceleration rate all the way up to the top speed, not just at the bottom end take off.

You can do the same thing with your finger on the throtle. Just dont pull it as fast and its the same as punch control, only you control it.

You got it exactly... Punch control slows throttle response, doesn't change end points or max/min throttle points.

I seldom run more than 10% punch control - it works great off the line, but it any higher setting creates a very "muddy" feeling in the mid and upper rpm range, making timing more difficult(the delayed reaction doesn't curve away as rpms increase). I have had good success with the throttle curve, though. I use a mild curve, basically 50% throttle on the trigger yields about 40% on my curve, and 90% throttle on the trigger yields about 80%. The curve slopes mildly at low throttle input and steeply at the end(so if I really want it all, it is available with a hard squeeze). It takes a few tries to get the throttle curve to a nice, driveable and predictable setting, but it works far better than punch control IMO.

THe throttle curve is the best tuning device for the Mambas. I run a 1512 1.5d on 4s in my rc8. I have my punch set at ZERO. With a linear throttle the car is practically uncontrollable on a track. Way over powered and very hard to keep the back end in control. With right gearing I can easily get the car up in the 60s.

I adjusted the low end of the curve to where it is very soft then pretty steep after half throttle and it works perfectly. I can creep around the tight turns and short straights and if I need to clear huge triples or doubles with very little run up, all I do is grab full throttle and it is bye bye nitro.

perfect. thanks guys this answered all my questions. 75% punch here i come hehe

[DRIFT_BUGGY]

Well what is the difference between that and 'start power'?

[blueb8llz]

sounds like you guys have a very good point there mike and edumakated. maybe its the throttle setting that i need to fool around with. so put my punch at 10% (which is 90% punch power...i dont know why CC made it this way, it should have been like the brake %...70% brake means 70% and not 30%.) and then just decrease the first half of the throttle setting?
