Nope it is not a Nitro or Gas twin, but an FE twin with enough juice to run against any power plant......hopefully.
This project has taken a couple years to get off the computer screen and onto the build bench and it's finally to the point where I can share some pics.
The tub measures 45" by 7" and is built from laser cut birch ply, reinforced with G10 and then carbon to wrap around all the walls.
Power will come from two Lehner 2260 size motors spinning 1/4" cables in the same direction. ESC's are a matched pair of the newer Schulze 40.161's.
The controllers have two pairs of battery leads for each ESC, one pair will go directly to a battery and the other pair connects to the other controller for IMPBA legality. Joining the controllers has the benefit that power will be drawn evenly from the batteries. It also allows me to run 3 or 4 packs in parallel for added capacity or just available batteries.
I intend to run this as a Q-hydro for IMPBA or T-Hydro for NAMBA both on 6 cells with at least 2 parallel packs. The RPM range should be similar to a big block nitro motor on 6 cells. I can always increase to 8 to 10 cells with higher RPM's if needed. A small electric water pump driven off the third channel will provide post run cooling.
Hardware on the back is from Mark Grim.
Next steps are to paint and then build front and rear sponsons.
