@Adanene idk, best thing is to get a better phone or to get a computer, tanks take parts.

@Mmdben @Minecraftpoweer
Also you too guys

@Ryn176

Maybe you can give me your opinion about my mbt imperion2

You either make accurate replica, or come up with a nice idea for a fictional one

How to make a good tank? Idk. Just look a real tank up
.
Proportion are key

@Adanene I think you'll have to to go through the lag buddy...

@Adanene
If your device can't handle the part count, I'm afraid you'll have to suffer through the lag. A detailed build will generally reach over 500 parts.
.
I'll have to go to greater lengths to explain everything you've asked me, but generally making an interior requires that you physically make a hollow hull of the tank in SP. This is already going to accrue you quite a bit of parts, especially if the vehicle you're making has a strange hull shape.
.
Recoil is an open path. You can model it with pistons, like most do, but I personally prefer impactForce recoil systems.
.
I'll stop here, you get the general idea.

how to make some interior, recoil,and other details if my phone become lagg after make 250+ parts on a tank? So sorry I don't know how :(

1.> Nope, they are not underrated. Just put a ton of effort.
2.> Add an Interior, Recoil, Turret, and Gun stabilizer, Markings, Realistic-ish reload speed, small quirks, little details, custom scope, realistic performance.
Ask the guy below me if you need any help (heheheh)

@SnoWFLakE0s Only kinda, it does show a a tank that was well recieved by the community ;)

@Minecraftpoweer Shameless self plug. Lol.

are they? I think its like how @SnoWFLakE0s said, but its the same with everyting, doesn't matte if its a plane or tank, people look for what works and is appealing.

First of all, tank aren't underrated. They receive substantial amounts of upvotes. It's just that Bronze or Silver users are bronze and silver for a reason- their quality isn't high enough.
Most tanks are also replicas. If you aren't faithful enough to the real thing, you likely won't receive good feedback.

1. Yes ,most people don't know how hard it is to make a tank so they don't take the effort into checking it out and on the other hand ,they can be very very laggy, like my Pc can't handle a 500 parts TANK TRACK but can handle a 1500 parts plane.
2. make it fly !!!!!!!-seriously I don't know how to make them enjoyable :(-
