Bob sent me an e-mail and I replied to him right away, but he hasn't replied back.

Neither should be any worse than a HV 4.5 on 5s.

Alright . The motors are ready and they'll be shipped on Monday. SpEEdyBL was right on the money with the Kv values. Here is what Bob has just sent me:

"Here are the KV tests I did on the two motors.



Input voltage measured at Speed control power input





Motor Vin Aload KV

2.5 5.0 3 7900 Free running (no load)

2.5 4.0 30 7125 Loaded

2.5 5.0 43 6960 “

2.5 6.0 57 6700 “

2.5 7.0 73 6515 “



1.5 5.0 9 12,630 Free running (no load)

1.5 4.0 91 9750 Loaded



As you can see the 1.5 is pulling a lot of current at 4 volts so I did not want to run it at any high load. My suggestion would be to run the 2.5 for most of your runs and then use the 1.5 for the last few runs in case it blows up.

We will ship the motors Monday."

FWIW, ALL linear BECs will have the same efficiency ratings, and as such, should be disabled when running over 2s (so 3s, and higher).

Just going by what the factory has told me. They said the BEC is good with 3S.

I run my MM with 3s w/ & w/o bec and i don't notice a difference in temps. I've also ran my novak hv max off a single 4s pack with and without bec and have not noticed any difference in temps. Could be the servos im using however. Cheap servos have always worked great for me.

The 2 custom Novak HVs will be here today and I'll be posting pictures of them. It should be cool to have the first ever HV1.5 and the 2 known in existance HV2.5 motors . I'm going to rub this in here for a while .
