Ordered up a set of these bad boys... YHR on RCUniverse gave them high praise as powerful, quiet and FAST...
AFAIK they're the only high/low motor configuration gearboxes in regular HengLong ratio with drive shaft bearings. These also have bearings on EVERY reduction gear shaft. A bit overkill if you ask me but why not?
Hopefully they can give my limping Pershing a bit of a boost!
Ed my initial thought is that these gears will turn a KV into a speed demon! Which is fine if that's what you want
The gears I'm pulling out of my Pershing are the same ratio as my KV-2, and it's plenty quick for a 15 pound tank... but I've also installed the faster motors onto the Pershing gears while my KV-2 are stock from Taigen. Would you want to try those out first? I think they'd make a nice fit... does yours have plastic sprockets (long shaft gears?) Remember the KV's sprocket is about twice the circumference as the Pershing, so everything else being equal it will be faster.
....also I want to sell you my gears Bwahahahah

Steel gears as well. Way too fast for WWII armor, but good for the Modern stuff.
These motors turn faster and have more torque then the HL Standard motors. On Par with Promax would be my guess. I had HL Steel gears with Promax, and I pulled them out and put these in resulting in a Faster Leopard.
These boxes, because of the bearings, actually free wheel. I had my leopard 2 on an incline and it rolled down the hill. The lack of internal resistance in the GB, probably makes it easier to turn resulting in more RPM.
I never scale speed tested either GB so have no idea what speed they are running. The Hobbyraw ones are very smooth and quiet.
Sorry that I do not have time to put them on website, like those M1A1 track, Leo Track, Patton Tracks, also those Torro KV2 turrets, upper hulls. and many parts for Panthers and JP. Then will be on the website later when I have time to set them up. if you interested in, really feel free to let me know.

So now Hobby Raw and yourself carry these, who's building them?
Any idea if they'd ever produce a 4:1 gearbox in the same style?
That would be sweet. I find these boxes very fast. They are OK when installed in a Leopard, but put them in a WWII tank (other then Hellcat) and they would be way too fast. Although with a digital radio you could adjust the end point to save the situation.
