First, I think the best bet would be to ask FW directly. I will venture a guess, though, and say probably not for a variety of reasons. The canals are generally clogged with duck weed, which would be a bit of a mess with a remote controlled boat. There are numerous waterfowl which could be harrassed by these boats. Occasionally alligators go into the canal system, although rarely, which could be a hazard to children going near the canals. There are several species of poisonous snake at FW, and they may be lurking in the weeds near the canals. And finally, Disney likes to have a LOT of control over their waterways, so outside watercraft are not allowed, keeping people like me from using our own canoes. I know the remote boats you are talking about are small, but they may take issue with it none the less. I know at times there has been radio controlled boat races at FW, but these have been held in the pool, not Disney's waterways, and it is under Disney cast member supervision.
