Gearbox's

[Moogie]

With being new to the tank world, i have a few questions.

Getting ready for my T62 3D print build i have been looking for a suitable gearbox and came across a couple of Heng long on E bay.
Do Heng Long use the same gearbox on all their different models ?

Would the plastic variants be strong enough ? The T62 will probably live most of its life on a shelf or on a trailer as a load but i would still like to be able to drive it onto the trailer if possible.

I take it most tanks are controlled by two ESCs and continuous turn servos for the turret ?

Not sure yet if I'm going with an aluminium hull or 3D printed in PLA+ . Metal would probably be more stable and robust.

That's it for now, will have more questions as i get further into the build.

no they dont use same gearboxes for all their models there are differant types of gearboxes ie a tiger 1 gearbox wont suit the panther/jagdpanther

I don't kinow if you can get Heng Long/Taigen Gearboxes or Control boards or Turret motors on E-Bay but that would be my start point, Certainly all the tunning gear for a T62 is available from dealers such as www.forgebeartanks.com

"Would the plastic variants be strong enough ? The T62 will probably live most of its life on a shelf or on a trailer as a load but i would still like to be able to drive it onto the trailer if possible."
If you don't drive the T62 outdoors or on thick carpet, the plastic will suffice. My AFVs are similarly inactive, but I still go for the best quality I can get--within reason. It's my quirk.

"I take it most tanks are controlled by two ESCs and continuous turn servos for the turret ?"
It would be much easier to choose an "MFU" compatible with whatever transmitter you are using. If you are in the UK, then, just as jarndice recommends, www.forgebeartanks.com is the one. If you are on the continent, you have some German retailers from among which to choose. I have used at least two of them. (However, the current political conditions make my buying from UK or EU dicey.)

"Not sure yet if I'm going with an aluminium hull or 3D printed in PLA+ ."
Metal would probably be more stable and robust." Metal might be a better choice for a modern MBT.

Here's what I would choose unless I were determined to make the T62 compatible with my own transmitter: HengLong or TongDe (seem to be the same) dedicated transmitter and TK7.0 (available as sets, not too expensive at all). HengLong true metal (not zink alloy) transmission and motors. That would give me a decent running tank at relatively low cost. Just my 2 cents worth.

Thank you very much for the reply's , it will give me an idea for what to look for.
Just need to work out which models gearbox in going to use. Going by dimensions the T90 seems to be the best candidate . Opinions ?

[Moogie]

I see Forge bear tanks have a TK7.1 radio and sound system (i think that is what it is) Is the TK7.1 ok or is the TK7.0 better ?

[AlanWhite]

the tk 7.1 is supposed to have more functions and is an upgrade from the 7.0

[Rob59]

The 7.1 can take servos which the 7.0 cann‘t
Thats the main difference!

[Moogie]

No problem, 7.1 it is then.

@Moogie Are you 3D printing the T62 and if so what files are you using? If they come from a certain designer (Inkor), there is a standard set of gearboxes he uses. If the files come from someone else then you need to find out which ones the files were designed around as there are several types. There are different motor mount heights like High/Low and Mid/Low. Then there are different gearbox gear materials like steel, pot metal, and plastic. Then there are different shaft lengths like 25mm, 49mm, 59mm, and 65mm depending on which gearbox you go with. Inkor's tanks are designed around ML49mm gearboxes (Mid/Low 49mm shafts).
