Finaly finished with this disaster...
I have to admit this was the worst experience in building suspension the I had.
Apart from problems with wheels, rocking levers and springs had no strong points of joint and tended to break apart whole time of assembling.
Supporting rods base, despite that it was glued with super glue, fall apart to layers all the time.
Eventually I managed somehow to glue it all together and make the tank stand fairly straight, but wheels on spring now work only as decorative - the body stands on rocking levers wheels only.
Pay attention, to put dry fit front wheel first. Later it wheel be difficult, though you need to glue it last, to prevent putting all the weight on single wheel.
Also, fellow member on other forum pointed out that idler wheels must also be with rubber bandages, so I painted those in black.
You can see it here.
Wheels and connecting beams assembled.
Everything put together.
Next are trаcks. Wish me luck
Errors:
part 626 not painted as part 617, to imitate rubber bandage.
