Herr Doc's Various Questions

[Jofaur86]

Mr. Prifesseur, if I could give you a little help? you see me delighted

[Herr Dr. Professor]

With much patient explanation and graphic help from Jofaur86, I now have my otherwise RTR HengLong Challenger 2 (in Nato camouflage) running with HL TK7.0. I have upgraded quite a few Taigen/Torro tanks to the latest (now outdated and outdone) Taigen MFU, and those were a whole lot easier to do. But I have made modest progress in skills of soldering and changing various sorts of connectors. My toolbox grew yet a bit more, too. Thanks to Jofaur. I am now eager to learn more about the Challenger 2 (Like Paladin: "Have Books; Will Peruse") No pics of the Challenger because it is going to be a budget-minded unremarkable build.

[Herr Dr. Professor]

I have a thread started pertaining specifically to my WCP SdKFz. 251. Please see viewtopic.php?p=368428#p368428 if you think you can help.

1) Is there a source for an MG barrel correct for the Challenger 2 turret "Chain Gun" coaxial with the 120 mm cannon?

[Herr Dr. Professor]

What is the small circled connector from this Readytosky 40A Bidirectional Brushed ESC 2-4S RC 40A x 2? It seems to be 1/3 of a servo connection? power only? signal only?

Yes. I have one on mine.

The single connector is just a Dupont connector with one pin. For an ESC, you only need one connector (3-pin) to provide power to the receiver. The full 3-pin connector would provide the 6V to the receiver so that you don't need a battery pack (battery elimination circuit - BEC). If this is a dual channel ESC, the yellow would be the signal cable for one channel for one motor and the other 3-pin would be the other channel for the other motor.

Amazon review of this ESC are horrible complaining mostly that the BEC (battery elimination circuit) cuts out a lot. Also says it's a frequently returned item.

[Herr Dr. Professor]

Yes, Meter rat, that's the look of the "chain gun," which term "chain,: I guess, refers to what we Yanks would call the "belt" of ammo.

Thanks for the tips, tankme: I will be on the lookout for troubles with the ESC. I though I had read all that stuff on Amazon, but I will check again.
