I'm proud to show my latest MOC...
This model is based on Tim Cameron's "Showtime" and other similar Rock crawlers.
The chassis utilizes NXT motors geared down 3:1, and one servo for steering the front wheels only. The NXT motors are connected using adapters that allow connection to regular PF elements.
This project started out as a "quick" experiment that soon got out of hand!!!
I enjoyed trying out ways of joining liftarms and seeing what shapes I could get out of them.
Things that I'm not too happy with are the shortness of the model, and now that I have found some better pics of Showtime I can see it should be 3-4 studs longer, and lower too.
The seats were far more leaned back, but due to the rear motor needing more clearance I had to pull them forward making the cab a bit cramped. LOL
As for performance, I was amazed, The Reaper will easily go up 45 degree plank of wood, that is quite smooth with no major tweaks.
Turning isn't the best, but that is to be expected with no diffs; and I tried to tune it to a nice balance of turning and NON wheel tearing.
This crawler has no gear grinding at all, and I am very happy with the new type 2 8t. also I rigged the PF lights to the steering so it kind of flashes when steered!
Edit: The shocks were made from combining Unimog and old bike sets, just to keep it black.
Weight is 1.320 KG.
After I have made a video (prob next week, Wed) I will reuse and tweak this awesome chassis, and hopefully make something a little lower.
Please feel free to comment, and ask any question's. If you would like a particular pic please ask soonish as I have the lights set up hahaha.
Thanks for looking.
