This is still listed as an R/c ( able ) kit,
The shop owner is sort of right..

What you will have seen is this :
Almost all of the Billings Boat kits that could be radio controllled..
DO NOT COME WITH ANY R/C instructions... thats a fact !
This has always been a major downfall of Billings, who never corrected the issue !
Their " get out " will be their statement about there are so many radio control systems available, it is up to the builder to sort it out !
Anyways, no worries... You will have all the help you need, here on MAYHEM !

There are many models that are "static" that can be converted to radio control.. ( and some that CANNOT !! )
Many Smits have gone before you... so do not panic !
