ORIGINAL: B.A.D.A.S.S.Force

I received my TK20E-T1 boards a couple days ago, a TK20E-RU board today, & just got the chance, along with a couple of Clark's high power IR010 IR LED emitters, to do a quick test.

For the sensors I had a standard Heng Long battle unit (HBU), & luckily for me, I also just got a Tamiya apple (TBU) in from the AAF Tank Museum today (super quick from purchase to door-step, thanks Karen), so I had more than just a Heng Long sensor to test.

I did this quick experiment outside in the dark tonight, using my Panther's lower hull as a target, just perching the connected apples on the rear of the hull by the exhaust, as parallel to the ground as I could get them to sit. My KV1 was used for the shooter, though the IR LED was mounted inside a small tube, 9mm from its opening, & just held in my hand for aiming.

Unfortunately, the ground I used for testing only has about 50ft of almost perfectly flat cement, then some uneven gound extended beyond the cement. But I was still very happy with the results, & I can't wait to fully install everything into the tanks to do some proper testing, hopefully on an area with well over 90ft of flat ground. Just using the standard HBU sensor I was able to easily get hits at about 50ft with Clark's IR010 IR LED. Using the TBU sensor, I was marking hits at over 95ft, though I have to say, the real issue I had at getting any hits, using either sensor at any distance greater than the 50ft, was more because I couldn't even see the target at longer ranges with the very low lighting in the area where I did my testing, that along with the more uneven ground I was on at those ranges ... so aiming was extremely difficult. I didn't manage to get any hits with the HBU past the 50ft, but I didn't really try too long either since I already got hits over 95ft using the TBU.

I'm expecting to get some TSAL5100 IR LED emitters within the next few days to test as well, & those have a higher intensity with the same 20° angle as Clark's IR010 emitters, so even better ranges should be possible. IR range isn't a problem any longer.
