Via email to Mayhem...Hi Martin
Attached are some pics of the tugboat I converted, thanks to you help! I'm happy to report it came out great and the first maiden voyage (in the tub, heh) was successful! Just in time for my daughter's birthday today

Although, for some reason the spray hose is not working but it maybe that I have to prime it somehow or the motor may be turning the wrong direction? Need to test more.
I ended up getting a 2nd speed control for the spray hose because it was $7 more and to me it was a simpler install. Battery placement was great with the two you recommended and I ran them on parallel for long battery life. Question, did your have foam to help buoyancy? Mine didn't but I may use some expanding foam, just in case.
Thanks again!
Pete
NB: This was Phil's shopping list:
Evening Pete!1.Speed controller (is reverse needed?)
Yes, reverse needed as you find out on your very first run!
Also best if it "waterproof" - this look OK:
http://www.amazon.com/dp/B00DU49XXS/ref=cm_sw_su_dp - Hobbypower Rc ESC 10a Brushed Motor Speed Controller for Rc Car Boat W/o Brake
This looks better:
http://www.amazon.com/dp/B00LXCM3Q8?psc=1 - HobbyWing QUICRUN 1060 Brushed ESC (1/10)
2. Battery looks OK. Other options are two of these ( for weight distribution purposes) :
http://amzn.com/B00LRUTW92 - 2x Pack - UB613 Universal Sealed Lead Acid Battery Replacement (6V, 1.3Ah)
3.Charger looks gooK too. This one will do just as well:
http://amzn.com/B001G8AIMU - Sealed Lead Acid Battery Charger UPG D1724
4. Radio. I would go for a Cheap 4 or 6 channel radio, just in case you catch the bug and want to build a 2nd boat (or car!)
Make sure you can get additional Rx cheaply!
These look OK:
