I'll try that later today just in case ... Thank you for your helpÂ

December 4, 20222 yr Long time without seeing a very smart and simple idea, thank you for sharing it.

December 4, 20222 yr Author After testing I must say that only traditional way works; reduction gubs should be used as hubs like on 42099 set; so only way is to use like on axle that has angled suspension arms based on Pythagorean theoremÂ

I used that basic idea in the rear propellor of my Canadair CL-84 MOC, though it was a non-planetary hub, and it worked well!

Â Honestly propeller has less friction spinning through the air than wheels that are driving tractor that is supposed to pull something (at least)... I feel honored that you gentleman give me suggestions and share your experience.
January 8, 20232 yr Author Christmas time work on front axle to make something like stiffness... sorry for bad photo quality Â
July 22, 20231 yr Ah, thanks Igor! You posted this before but completely forgot about it.... A shorter liftarm with ball socket is needed desperately! :D

A shorter liftarm with ball socket is needed desperately! :D If you are interested how re re redesigning of Fastrac is going; now all motors are placed inside central chassis part which includes 2 XL motors for drive, servo for steering (unfortunately no space to put one servo on each axle) one m moror for front pto and one for rear (you can see that one is turned to front and one to rear). Now since I needed more than dozen iterations toake something like that compact and stiff enough, I assume that until end of year I'll find a way how to make front part that will include battery box below bonnet (it remains unchanged) and to enable some stud, stud and half suspension travel on ftont axle. ...now I realized that I forgot to turn of rotation on ma mobile phone... Special thanks to @Zerobricks, @Philo and @gyenesvi who helped me with their experience when coupling 2 PF XL motors
July 25, 20231 yr Author ...at least right side with stairs and toolbox is finished... ...later I have replaced light bluish gray dogbones with black ones on front axle
July 28, 20231 yr Author Finaly left side is made as I wanted, so @eric trax, @Jundis and @Thirdwigg please tell me if I can make something better.

The front is for my taste too much system bricks, but agaiin, this really is my personal taste. Instead of the slopes maye use these on the upper side? However, it wouldn't be that clean. :-/
July 29, 20231 yr Author @Jundis unfortinately I have only 2 of them (for fuel tank); this idea crossed my mind but then I could not make second stairs Âœ stud positive offset (to inside) because tractor has a bit amgeled stairs to the left and space on 1:15 scale is 3 studs... This picture illustrages how left side looks like Â
July 29, 20231 yr Author Front axle and place for battery are finished (and very sturdy). Front axle has one stud suspension travel, so I think becayse it us a tractor (and not range rover) it is acceptable.
