Hello
Just thought I would add my 2 cent, the model has a 4inch opening in the first former that allows access for a canister with no tunnel built in.Out the box the plane was tail heavy on the aft range of the CG, this is with 2 2cell A123 2100mah up in the nose of the engine box
. The EME 60 which was awesome on the pipe in another plane was not so on the regular muffler with this 19lb plane, as such I made the decision to build the tunnel and install the pipe. Now with all the trying of different mufflers with this un-usual inside structure of the cowl I had to cut out 90% of the bottom of the cowl to fit the mufflers and as a result this now gives full access to the tunnel opening.
