Hello Jesse,
A few more pieces of info. The Challenger 43 was shipped with 6mm thick stringers for a gasser set up. I removed the stingers, smoothed the epoxied fillets, and then epoxied a full length carbon fiber/ Kevlar 5.5 oz fabric into the inner hull. This was done to facilitate the 10,000 lipos to each side of the motor and to keep the weigh lower in the hull. I also used OSE Qiuck Change Motor Mounts for the TP 4070. The typical TP cooling jacket is somewhat narrow and does not fit well over the motor can , so I went with an OSE Water jacket 40 x 70mm long. My Challenger runs with a high temperature of 95 deg F in 80 deg F pond water. Also my COG is closer to 34%. With the COG at less than 34% my Challenger wanted to come out of the water and fly or go sideways. This was not a very good handling scenario, so I ended up adjusting the COG forward about 1/4. This resulted in a much more stable and easier ride. Check out this OSE forum link for more information on the Challenger 43. https://forums.offshoreelectrics.com...=Challenger+43
