long time ago.
i have experience on tamiya clone that previously build
such TL01 rtr for 18$
i think 80% is a waste on this rtr.
i would throw useless transmitter and speedo.
replace almost everyting but chassic and arm and some gear
i have to replace the planetary gear.
any of the material was verry disapointed crack able,
since it was planned for toys.
because it was planned to run on 540 can, without parts replacement suppplied by the factory.
Big disapointed, better use mchassis
and i think http://www.toptoys.cn/en/
was the same
i guess they were plan to run on 20C only,
as the name was toptoys, they were plan for toys, not racing.
there is no prove that this TK416 is race able for mod's yet,
as a tester i would pay
TK416 for 50$ or less
and must be parts supported supplied.
and as clone it should be compatible to all 416 tamiya factory.
other reason not to to buy, i could not trust china,
will stay with this kit for long term.
unless there is video to show :
2.5t test for 15 minutes on race circuit.
worn out test.
remember i have been there testing between tamiya tl01 with china tl01.
and china tl01 is very disapointed on cost and quality.
