I can concur. HK radios and receivers are great for Tanks. I use the Hk T6A that has 6 channels with 5 and 6 being fully proportional with rotating knobs. For my DBC3 equipped tanks this means I can use channel 5 to control gun elevation with a servo and channel 6 can be mixed to run a recoil servo when the gunfire is activated.
I don't know why anyone would bother with the Factory upgrades to 2.4 gHz offered from Taigen and Heng Long.. The HK T6a is a far better radio that moves you in to the proper PWM standard and away for the proprietary signals that are used on the HL or Taigen tanks..
I can understand the concern if I was flying a $12,000 jet, but for a land based slow moving tank that is typically within 100 metres, these HK radios are more then adequate. This is the radio I decided on when I sell packaged units of DBC3/TBS/receivers to customers who just want a completely plug and play experience. It allows me to program the radio and the DBC3/TBS combo into a simple drop in electronics package. I have never had a failure of the radio or the receivers in this time, and in fact my Spektrum is the radio that is having issues with the potentiometers right now.
So yes, you can buy the electronics and servos from HK with no fear.
Thank YHR
yes i have had a couple of those radios they work pretty good i will probably check out the servos from them
