PC650 undercarriage gear problem solved

 original straight bevel gears known to be not good,

 and now we found the solution to it..

 Changing to bigger and better hypoid/spiral bevel gears...

 upgraded undercarriage jumbo gearing, look alike a grinder head..lol.., no problem to smash anything on its path..still using same high tork geared motor, super power

climbing 30degree angle with no issues, see below:

My sick-baby...track system waiting to be upgraded..

also upgrading the radio system, changing to 9Ch TURNIGY TX/RX system...
smaller, more hi-tech and complex.. fuh..too many switches now..

 Zoom in to TURNIGY RX..using glider mode, coz EXCAV mode is not available at this moment..sigh!

 all the stick functions work exactly as per real EXCAVATOR, so if you know how to drive one, this one just a piece of cake.. the track function is mod to use the 5th and 6th Ch... extra Ch for Hyd pump/motor, and left 2 more Ch for extra things in future..
