really, really cool

planetary gears need a complete chassis rebuild, because the rear axle on the stock volvo is placed to much in the back. so you use better my 350 moc

two things use the link from the share button on youtube use a media tag instead of teh URL tag [media] [/media] and use http instead of https

have you used http and not https?

Sometimes for the look, sometimes for structural needs.

The diff is in a 5x7 frame and is driven by a 20 tooth double bevel. And this 20 tooth is drven by a 12 tooth double bevel above. These two gears should normaly placed between two triangles, but this is not the case on these axles and under high load they jump over. My last setup was really rocksolid, but the frame was really high and the chassis was zero kat 1, and i want a kat 1 chassis. So i have to use one driveshaft.

The planetary gear is the same like in this axle. Yes thesse are the u joints i have used, And yes these are my ansmann tires.

there is no plastic killed. on every axle i have a 12:20 combination which seems to jump over when the load is to high.

I at Play? has this something to do with IP car?

now its weight is 4850g with batteries, and the drivetrain is sometimes a bit overloaded

The weight before the flatbed was 3,6 kg. The reduction in the wheels is 4:1 and in complete roundabout 11:1

the set isnt optimized yet. more than 10 euro would be saved. flatbed is mostly done

Lowering of the outriggers is manually?

I use an older version of the cyberlink power director. It can all what you want and it works very fast. But unfortunately you have to pay for it. Edit Do you cant edit the video for your foldable crane?

like this? to large edit: after some dissassembling i know what was the reason for the most friction Someone has put a nylon washer between diff and 5x7 frame to avoid the juimp over the 20 tooth doublebevel gear. My 4 bevel gear diff has this washer in the mold. and this washer surface has made the friction. some grinding and it works much better now

thanks guys

I use one lipo for two xl and a third lipo for the receiver. Sure, more amps result in more torque, but killing the friction is first to do.

Yes, only one receiver for four xl motors

One receiver which powers a servo, which switches two pole reverser, wich are powering the 4 xl. Steering works with a pf L.

this is exactly what i have done, fortunately the springs of the large shock absorbers are fit inside, but unfortunately this results in a lot of friction. And you see in the video that the 4 xl are nearly stalled in some situations

the large driveshafts are arrived the slide works perfectly, unfortunately the printed balls are to small and my two pieces 2907 sliding off the crossaxles

It is a 4 to 1 planetary in the rim and there are 4 bevel gears in the diff. I will se how much torque the diffs can take before something is cracking. And diffs are not evil, loosing ground contact is evil. The steering angle on the front axle is roundabout between 35 and 40 degrees

a offroad truck with some on the back btw, the cab is done with working steering wheel
