This model was originally built by me, then sold, then retuned to me at the last SUBFEST event. It started out as a stock Thundertiger Neptune, but underwent cosmetic modifications to turn it into the "Silver Stallion", paying homage to the paint scheme that mimics the P-51 Mustang of WW2. 

This submarine has an upgraded scimitar propeller and a brand new brushed ESC. It has a FrSky receiver, ready to accept a Tandem or 900mhz receiver for unequalled control. 

I can't say enough about how well this sub runs. It is quick enough to be fun, but smooth, stately and very easy to control as well. Turning radius is just abou it's own body length, making it perfect for a pool or other enclosed body of water. 
 
The package also includes a custom hard-sided plastic carry case with foam inserts for safe storage and transport... a $300 value!

These Thundertigers are near impossible to find, and certiainly nothing as unique as this boat will cross your path any time soon. Move fast!
