I have been racing RC since 1991... no time off...
all scales and all types of tracks ( 1/12 electric to 1/4 scale (gas)
Carpet, concrete, blacktop. concrete with soda pop coating.
also flew RC aircraft for 6 years.... electric and nitro.. 40 size to 120 size.

Radio and Servo's ..... Futata.... all that time.

3 years ago I moved 1,800 miles
and started to race Dirt 1/10 scale. SC5m

I installed a Futaba 3305. .. it lasted 2 years... ( sad )... replace with same...

next one will be a Tekin.

fyi.. I have NEVER had a sponsor... except for my wife.
I do know may Sponsored drivers,, then and now.
from the US Indoor Champs..... Cleveland Ohio...
raced with them for many years, at the local tracks.
<< I NEVER race a big race... just wrench for friends that are / were sponsored.>>

MY OPINION, and is worth what you paid for it
