I haven`t been on this site in months and Nothing Changed.
-I thought everyone would have put their Pro 4`s away by now.....?.....I was wrong.....Ha Ha!
There`s very little Pro 4 parts available out there; so be carefull when you Run/Race it. . . . .-My Pro 4 is on a Shelf(I`ve had it for 3 years). I don`t want to take the risk.
For a good Set-Up: -Stay very close to the stock build.
-I don`t use the 1-Way(it`s crazy).
-The Spool works very well on Asphalt that is prepped(a good sweep). But you will kill Ring Gears if you`re hard on the throttle and brakes. . . . .Best with Stock and 19-Turn Motors.
Take Care
