Will the Heng Long 7.0 or 7.1 work as a replacement for Tongde 2.0?

Having problems with my Tongde control board and it was mentioned to me that I can replace with Heng long which some feel is a better board.

Yes, any HL radio later than TK-6 will work with the Tongde RC tank. The HL are functionally equivalent and has longer control range. You must replace both the transmitter and the MFU together.

I use a TK-6.0S transmitter and MFU on the Tongde M60A1. It replaced the TDX2 radio because I want the longer range. The HL TK-6.0S became available when I upgrade the Leopard 2A6 to servo recoil and TK-7.1, The Tongde changeover is very easy because the 2 MFU are plug compatible.

Or you can wait to get the Tongde 3.0 board and install it in. I plan to do that for my early Tongde tanks.

Issues are popping up with the TD 3s. One big one is their range is limited to ~1/3 that of the 7s. Better to stick with 7.0 / 7.1HL systems still.

How is the TDX3 improved over the TDX2? The TDX2 is pretty comparable to TK-7's in feature and driving quality.

It has the servo ports activated, is more IR compatible with both HL and Tamiya. It's also supposed to have slightly higher grade of electronic durability(?). There are some driving algorithms changes that appear to have been done as well. It's reportedly smoother driving, but that is subjective because every tank drives differently and it is only out in a few tanks (no in M60s yet).

Its about equal in the level of changes that HL made going from the 6.0 to 7.0 (6:1 ot 7.1).

Reports from those that have them are mixed so far. They are still too new and too few to make any solid conclusions. The best bet if changing MFUs is to go with the proven HL 7.0/7.1 systems as these are at present very reliable.

The TK7.1 will cost you over $60

If servo recoil is NOT in your plan, the TK7.0 works perfectly fine and will save you some dollars.

I share 3 HL 7.0 transmitters among 6 HL tanks, both TK7.0 and TK7.1. Just watch the binding process when switching them on.

The main reason I swapped out a HL 7.0 was the better speed adjustment and in my opinion smoother running and turning
