Is the Ultimate Gearbox from Heng Long worth it? These ones-https://www.forgebeartanks.com/store/p1100/Heng_Long_Ultimate_Edition_II_Long_Shaft_Steel_Gears_for_1%3A16_Scale_RC_Tank_Challenger.html

I'm looking at the ones from Forgebear tanks, but they are M+L, not H+L. I assume that means Medium and Low? Will that fit in an M26 Pershing with a smoke unit?

And finally, are these gearboxes worth it? Are they reliable, strong, etc?

Thanks

Hi look again at the THREE Heng Long Ultimate 11 gearboxes on http://www.forgebeartanks.com and you will see that there is a choice of short, medium and LONG shaft boxes available,
The list of Heng Long Tanks that the Long Shaft boxes fit are the challenger, abrams, PERSHING, bulldog, kv1 and the leo 2a6,
I bought a pair for a Panzer 4 to replace the Heng Long Pot metal originals and they are well engineered and they run quietly and the added bonus is that they were the easiest gearboxes I have ever fitted to a Tank,
All the mounting holes were easy to access and the power cables because they come separately allows the two motors to face each other without any interference from the cables which can then be easily slid onto their respective spades,
Do remember to keep hold of the old gearbox mounting screws because they are not included in the box.
In my opinion they are worth it.

Mr jarndice, any idea whether the gear ratio is different to the old boxes? I don't mean the 3:1 or 4:1 useless misleading nonsensical crap, I mean actual ratio, is it still the 39:1?

Mick I truly have no idea,
I work on the suck it and see principle when it comes to 1/16 gearboxes,
Indeed if the makers of these devises were to advertise a full size lashup using the same flowery language that they use on us they would soon be in court for breaching the trades descriptions act. :lolno:
If you were to show one of our 1/16 gearboxes to a Roman miller of the 1st century after he had stopped laughing he would point at the wood and stone handmade gearbox that had been working 24/7 for a hundred years with just the odd daub of animal fat for lubrication before selling you and your gearbox to the legion for spear practice :haha:

I'm not sure about wood and stone gearboxes but Asda still have Christmas stocks of goose fat.

I couldn't agree more with you regarding the misleading labels applied to the current range of boxes but, even with accurate ratios provided we would still need to factor in the diameter of the drive wheel. Maybe some one here who has access to all the currently available types could do a gearwheel tooth count and then calculate the final ratios and publish a table? Maybe!!

As to the quality of the new HL steel boxes, Dave of Forgebear showed me one just after they were released and they are solidly made, nicely finished and with smooth gear operation and shafts ball raced they appear to be as good as the best competition. Plus they are bright red! I just wish the build quality of the brushed motors were as good but they seem to work fine, as do the new steel geared boxes found in the latest RTR tanks, though not red :(

The ones I'm looking at are the ones that say "Heng Long Ultimate Edition II Long Shaft Steel Gears for 1:16 Scale RC Tank Challenger"
It has the long shafts, and it says they will fit the Pershing.

But the motors are blue?

The motors are indeed painted Blue BUT the Gearbox frames are RED.
Historically red is Hot and blue is Cooool,
What more could you ask for :haha:

Just one thing- The motors are mounted centrally, as opposed to the very end, or so it appears. Will that leave enough space for smoker unit?

Hi, The wording for the Heng Long Ultimate Edition 11 Long Shaft Steel Gears starts by stating---
"These Gears are from Heng Long and are for their range of 1/16 Tanks",
As this set of gearboxes is specific to the Heng Long Pershing and assuming your Pershing is a Heng Long Model and that the smoker is an original heng long smoker and is fitted correctly then all will be fine. :thumbup:

I’m going to crawl out onto a small limb here but smokers look so fake with the “out of proportion” appearance. The first thing I remove is the smoke unit. Makes more room for serious electronics or cleaner wiring. Just an old graybeard’s opinion.

In the early days of Heng Long Tanks you could measure the life of the smoker in hours so lots of us did as you do and used the space for something useful,
After all a Tank fitted with a properly serviced petrol engine should not make smoke especially one using fuel injection.
And now one of the selling points of the latest Heng Long Tanks is a smoking gun barrel which seems to ignore the fact that Tanks use smokeless ammunition and have done since WW2. :lolno: and yet most of us (Including me )paint a matte black smudge around the muzzle brake when it would probably show very little sign of use in service.
And as we are often reminded Tamiya Tanks are the epitome of accuracy and they don't have smokers. :shh:

If you go to "3:1" gearboxes you can't fit the smoker in there, unless you get the H/L. Just so you know, gearboxes come in three basic configs, High/Low, Mid/Low and Low/Low. In my Pershing I run the black steel, ball bearing Gearboxes from Imex, in the H/L configuration. Have you seen this thread?

You might find it informative. Hope that helps. 8)

OK, first, no offence but you're in Maryland, why are you trying to order from the UK? Go to Imex in Florida. Free shipping over $75 and you'll have the stuff in two or three days. I run the 3:1 H/L in my Pershing for a bit faster top speed (I run the same GBs in my M41 Walker Bulldog), but the 4:1s in your link will also work fine. Here's a link to Imex

And if you order from them make sure to write RCULOVE in the promo code box and Erik will send a free gift.

If you're looking for alternatives, FMP has been offering their double differential gearbox for some time, DKLM offers same exact gearbox under their brand & Hooben recently jumped on the bandwagon with their version due this month.

As always top advise from Max BUT perhaps a cautionary word,
Imex Florida is a Taigen Dealership and Eric is probably the most helpful person in any dealership in the lower 48 but not all Taigen parts are interchangeable with Heng Long Tanks so before dipping into your pocketbook I suggest you always check first :thumbup:

The sight isn't working for me right now. (Imex)

I think I'm going to get the Taigen ones. Thoughts?
