Re: Slow forward, fast reverse

Ok. Got all this checked out last night. Same problem. Runs like a scalded ape in reverse and a wounded dog forward. And not sure if this is a normal problem but when I rotate the turret and raise or lower the gun I get a horrible beeping noise from the speakerJimigood wrote:Jay-Em wrote:In the FAQ-sheet it states as follows:
Faster forward than reverse:
Forward movement is slow but reverse is faster, even with stick controls correct.
The solution:
The left and right motor wires are plugged in wrong way round AND the throttle channel is
reversed. These two errors cancel each other out so the tank moves forward when stick pushed
forward, but the IBU2 is thinking it is reversing and reducing the speed.
.
If plugging the mini-molexes in the other socket doesn't help..well..
hmm..
*scratching head*
WAITTAMINUTE!!!!
Start by setting all channels back to "normal, return the mini-molex to the config they had when the tank was original, ie. red in the left, black in the right when looking at the raised arrow-like thingies on the mini-molex. Red should be in the side where there's a notch in the mini-molex' side. It's hard to see, but it's there. Also check if the red cables are, indeed, soldered to the " + " of the motor. (not unimportant..)
If all's well we are back to a "normalized" state.
Now take-out the Mini-SD card.
Put the mini SD card in your PC card reader, locate the IBU2.ini and open it, look for the entry named "PowerMotorScale = 100; [1..100]% Check if that's at 100. Change to 100 if not.
Next look for ReverseSpeed = 50; [1 ... 100]% check at what percentage that is set.
For ease of control, I'd set both at 100, in that case odd motor connections won't make a difference.
You could also check CurrentMotorTreshold = 10; [1..15] I keep that at 12 It's the max amps a motor can get. Some powerful motors use more current when running forward, and the IBU will throttle them if this setting is wrong.
When editing the .ini, be careful with spaces, they totally confuse the IBU2.
If stuff keeps running wonky, it's also advisable to check
RadioCH1InverseCmd = FALSE; TRUE / FALSE
RadioCH2InverseCmd = FALSE; TRUE / FALSE
RadioCH3InverseCmd = FALSE; TRUE / FALSE
RadioCH4InverseCmd = FALSE; TRUE / FALSE
Stock should read "FALSE" change it if it's not as such.
Those settings are sometimes adapted by the seller to fit a particular transmitter, with the net result that using a different TX results in the weirdest stuff.
I had that problem (or rather HEADACHE!) with a Carson redflex 6ch stick. Couldn't get it to work whatever I did. After dilligent tweaking of the IBU2.ini I got it working for a bit, but was so frustrated by the ordeal that I threw the Carson in a box on the attic, and ordered a Turnigy i6, set everything in the .ini back to default, and haven't had any trouble yet (plus the great sounds of a custom Jagdpanther sound set..)
If You haven't got a cardeader for mini/micro SD, You're in trouble. Luckily usb card-readers with the correct slot are aplenty and cheap. Most computer shops have them, I even spotted them at the local "Action" (China crap outlet)
Lemme hear how it went with my tips.
