So my Leo is too heavy and looks like it's leaning back rather than being level after a run. The picture does a better job of describing it.

Any suggestions?Image

open it up and stick a bit of sticky lead weight in the front
that will help

Better yet but the uprated spring kit!

Or you can try clocking the springs first

Cheap and easier. How much do you suppose the weight would be?

In reference to both your replies? Updated kit?
And how do I check the suspension springs?

This tip wont help with your problem but if it is always advisable to support a Tank when it is on display to take the weight off of the suspension to prevent it sagging.

Nothing worse than a lot of weight causing sagging. . . .

Personally. After looking at the picture, I would beef up only the rear two pairs of suspension springs either way Tom suggests, but I would also beef up the front pair while I was at it (it can be seen in the picture the front wheel is being pushed up by track tension alone).

That evident, eh?
Any threads I can refer to to help me do this?

Thanks gunner. I'll have a look at the arms when I get the chance.

You can use fishing sinkers or tyre balancing weights (or since you're in America, perhaps buckshot :haha: ), add them gradually until it looks like the tank is no longer leaning backwards.

Oooh I'm staying far away from buckshot. Let me see if I can find those sinkers.

It could possibly be track tension too tight. The front roadwheel is being pulled up because the tension is overcoming the spring rate. If the metal sprockets and tracks are new, you might find that after you have run it around a bit and it has all stretched and bedded in, that the ride levels out again.

They're Taigen tracks, default size. Meaning they're the only size that won't make track slippages a daily thing. One more link and it becomes too big. I've run this around quite a few times, still hasn't sagged even a bit.

Do You know if the springs can be locked in a different hole? I havent had to remove my Leopard’s roadwheels, but on my T-90’s the rear two springs, and the frontmost spring are in the hole that increases the tension on the arms, and it balances the whole affair, metal reargearbox plate (Wecohe), heavy steel gearbox, fairly heavy speaker and all.

By now one T-90 weighs in at about 4,5 kg, and no sagging whatsoever.

My Leo also doesn’t sag, but it could be because the heavy rear gearbox is evened-out by the big FRS7 speaker up front. I run the lighter Tamiya Leopard tracks, by the way.

Oh, before I forget : did You check if all arms run free, and there are no broken/unseated springs in the rear?

If none of the ideas help, it could be necessary to switch the springs around, rears to the front, fronts to the rear. I can imagine the metal roadwheels wearing-out the springs due to their sheer weight.
If all else failes, a bag of stronger Heng Long springs is about €9,- or about $10,- I usually need only 2 springs to even-out sagging rear-or front ends

Just remember. The running gear doesn't contribute to the sag. Be it metal or plastic. But hull interior and turret do.

Is there a Corley suspension for the hen long modern tanks like for the Tagen ones?

Quite right sir. That's because roadwheels are unsprung weight. Gravity goes down, not up. We haven't got a black hole close enough to change that yet.

With the tracks being metal and so tight and the suspension springs so weak, they will pull on the further most suspension arms.

Metal tracks can cause this problem. With real tanks, the tracks are so heavy they sag above the roadwheels causing a slight tensioning effect. For the same to happen with our tanks using metal tracks, we'd need them at least twice the weight, and because we can't imitate scale mass of metals because atoms usually stay the same distance apart (there are exceptions, like star type gravity and some manufacturing processes). Therefore, we have to clock the suspension at the ends and fit tensioners to gain as near to smooth running as possible.

Lastly, listen to real tanks, you can hear the tracks clatter, and can hear some tracks trying to ride off.

Mr wibblywobbly is right, that's why clocking will help. Surely when you got the tracks you received a few spare links and pins? Sadly after your efforts to sort this problem, you'll possibly need tensioners.

You mean to change the preloaded on the coil springs? Would that be useful in regards suspension lifetime? I would assume you would need stronger springs, not just more preload?
