I have put this Rx/DMD into an older ,non S/S heng long Tiger......wished I would have gone with a plain ole S/S Heng Long controller unit(at least I would have gotten the sound and all).I personally was NOT happy with it for a few reasons.
First, the setup gave me a hard time! I followed directions to a "T",took many tries to get it to work the way I was happy with.
Second, I DID install the caps that come with it, and it still has that electrical sound/humm as if a transformer is about to blow!
Third....I now have NO turret rotation, gun elevation or BB fire capability........again, should have just got a S/S controller from Mato toys!!!!
All just my own opinion.......plus I gave up on most of my HL and am concentrating my time on my 3 Tamiyas(Tiger,King Tiger, Sherman) and my 1/6 Tiger
