I have the 1105 and my mate has the 1107 and we both run 4s. Both machines are ballistic but we can not tell the difference in performance....both running a 9t pinion. If you have not already bought cells, I would recommend 4s as there is no heat probs at all and the power is superb.

"I have the 1105 and my mate has the 1107 and we both run 4s"

Surely the run times are different on these, any possibility of getting specifics: temp, time, head speed.

What are the KV's of these motors?

Thanks.

Yes, we both run 325 blades. As for specific temp, the motor and batteries are not even warm to the touch, so no need to check that really. It does feel like the motor has not been run at all, I know that sounds strange and was not what I expected, but that's how it is. My eolo on 4s runs a Hacker C40-9L and that does get very warm, but the Trex is stone cold, yet has awsome power.
Regarding headspeed/run times, I will do a check this Sunday at the field on both machines and give you the data Sunday evening.
