Amazing!

Makes me want to grab some PVC and the largest motor I can find, check back next week for a flying sub :P

Out of curiosity, what is the power plant to this sub?

For a brushless motor for a model this size I would say a CD-ROM size outrunner of 2-2500kv on 2s would give you very good performance. Or alternatively a 26mm inrunner of similar KV.

Hi,
This is a spare part of RC Jet Boat.
http://happysuntoys.en.alibaba.com/p...at_R03916.html

I bought it in local bid market, with or without motor.
Please search "RC jet boat drive". You will see a lot on the web.

There is a big metal one on HobbyKing.


Love to see you building a BIG torpedo.

Arthur,
Thank you. It looks fun enough that the Scout kids could have fun with and maybe the adults too! Great work on this!
Peace,
Tom
