DSM has been berry berry goot to mi!
My Helios has a SPEKTRUM DSM PRO with a MICRO RX and it matches the speed of the Helios's module and reciever. The only time I've had a glitch is when the battery pack needed charging.
If your glitching? Start with your battery pack. If the wires are frayed or it doesn't peak as usual, change it. Check all the connections on it and re-do them if neccessary, then use shrink rap to keep them together should you crash. In my experience a good battery pack will stay that way as long as the connections are true.
I'm placing emphasis on the battery pack because of my own and my close friend's experiences.
Say your full throttle on the straight and your car suddenly steers one way or the other then gets back in your control.
This is caused by LOOSE OR BROKEN BATTERY BARS on your pack.
My buddy Bert bought a pack from a local hobby shop in Brooklyn, NY that was put together using braided laces or string coated with solder. This becomes brittle once the solder goes onto the string and when it cracks or comes loose you have and instant on-off switch causing glitching. When it completely breaks off a connection? Bye bye car...
His just fractured and would intermitanly loose contact whenever he was full throttle due to the vibration. He thought it was the reciever and replaced it... Still glitched so he replaced the servos... Still glitched... $300+ later, I gave him a 2500mah battery pack I put together using thin but solid battery straps and no more glitching. That was in '06, and he's still using the same pack without incident.
Moral of the story is, star the process of elimination at the battery pack.
Don't be afraid to take it apart and re-solder it with the best wiring and battery straps available. Make sure you shrink wrap the pack as well.
Hope ths helps
