I took my 600 out for the first time last weekend and got one flight in with the Eagle Tree data logger hooked up. The equipment used in this flight was a stock Align 75A esc, Neu 1515/2.5D/F/H 1700kv motor, and a Thunder Power Extreme V2 6s 5000 pack with unknown cycles. I was surprised to see how many watts this system is pushing. My T-Rex 500 tops out around 940w or so and I figured that the 600 might pull about 1300 watts. I was shocked to see over 1700w and an average of 1000w. That equates to 2.3 horsepower with an average of 1.3 horsepower. Now I see why the 600 is so rough on 6S packs. With the 85A spikes, I know that the stock Align esc will not last very long. I have a Castle Creations Phoenix HV85 sitting on the bench waiting be installed. I just have to pull the motor and install some larger 5.5mm bullets that I am using on the HV85 then program the esc. Hopefully I will get it all done tonight and test it again tomorrow.
