dx3s not getting enough travel on both channels?

[junkman]

I just bought a dx3s, I admit I was dazzled by the gadgetry. Up until this point I really just used whatever was laying around, had m8's, nicer jr's & such. I had bought a losi mini lst2, and a few extra receivers, and have been using it's stock radio on an e-revo, and homebuilt e-revo-slayer, and 1/5 scale, and everything worked fine. I binded up the recievers to the dx3s today, and noticed right off the bat the 2 electric cars were not as fast, and would barely turn right. I can swap back to the stock losi radio, everything is fine. I can max out the travel, to the right, and throttle foward, and can get the esc's to go full throttle, but even with the travel at 150%, it will not turn to full right lock. Is there something I am missing here, did I get a bad one? I have never ran into a radio that had to have the travel increased out of the box, and the fact it is just foward, and right turn seems even stranger. Thanks for any input.

Was that the EPA you were adjusting? Are the trims on those channels centered? Is there a neutral band setting? Just brainstorming here...

Not sure, but you might have to reprogram the ESC for the new radio. I would think you might since the whole point of programming it is so it knows what full throttle, brake, and reverse are.

^^ Yes. But what about the steering problem?

Thats what I can't seem to figure out...

Thanks for the replies, The only thing I have been really messing with is the "travel" Right out of the box it would turn all 3 cars left to full lock. If I turn it right, and hold it, then turn the "travel" up it will increase the throw, but still not all the way. The trims are at 0. I haven't messed with the exp, honestly I don't really remember what that is for. I didn't even think about relearning the esc, one of them is a mamba max, the other one is one of those cheapo yellow 100a ones. I was thinking they just armed at neutral and self set. I guess I have been used to just plugging it in and it being calibrated close enough to work properly with whatever radio I was using.

Are you using Spektrum recievers? It's a shot in the dark, but if you aren't, then maybe the Rx is the problem. It really does seem like a neutral band issue; with the Tx neutral being more to the "left" on all of the channels. You can probably correct it with the trim if it isn't wayyyyyy off. That's really just a patch though, the problem still exists.

Ok here is what I came up with. I took a servo put a really long horn on it, cut out a piece of cardboard and dropped it down in it. I took 4 radios, 0'd out the trims and started at their out of the box epa/travel. I moved the servo back and fourth, and marked their max sweep on the cardboard.


dx3s @150% on travel, is pretty much equal to the stock losi spektrum radio, you can put a bit of pressure on the losi radio and it will go past the dx3s max endpoint.

A futaba 2pl, at 100% is in between the 100 and 150% endpoints of the dx3s, and the 2pl's max of 120 it is pretty much equal to that of the dx3s max.

Last I tried my m8 with a spektum module, at 100% epa it was about where the futaba was at 100%. At 150%, its max, it def travels the farthest of the bunch, roughly 1/16" past where the others stopped.

I guess what it boiled down to is the dx3s endpoints are just a lot more conservative at out of the box specs. When it wouldn't hardly turn it got me paying closer attention to what was going on. The other radios just had enough thow I really didn't notice driving it I could have gotten more steering. I still don't understand completely why it takes so much more throw to turn the 3 cars I have tried to turn right than left, I guess that is just the way the steering is set up.

So far I am happy with the radio, happier now that I know nothing is wrong with it. I need to get some servo extensions to get the telemetry working on the baja, got the sensors mounted but need more leads. I have a wireless pet fence that had been giving me fits with the the brushless cars, that seems to have gone away using the spektrum stuff- the m8 with the module, and the dx3s. It doesn't bother any of the brushed cars for some reason.

Thats kinda strange. I personally always set it to 0 and 100% EPA, center the servo, then adjust the EPA up or down till it hits full lock. Usually up though. Just got to be careful not to put the servo in a bind at full lock.
