We use to run VTC (previous speedo from Orca) and the VX while being quite smaller run as cool as the previous one but with a much flatter powerband meaning more torque available on the whole band. So much that my 7.5 has become too much motor and I started using 10,5 again as on track I don't feel a hole in mid band as I was previously.

Freq drive is a must too as it allow a very smooth power delivery.

Was expecting a lot but got much more, for me one of the best on the market today by far.

Hi tomtom do you find the mtors stay as cool with the new speedo compared to the VTC? It sounds like you've gained more mid range power, very interesting....

Yes it stays as cool as the VTC.

The VTC was cooler than the motor (still run one on my 4wd) but the VX run hotter than the motor but far from thermaling.

I ran a fan this summer with boosted 10.5 but it's fine without one. my buddy didn't use one with a 7.5 and so far no issue (he does run a lot).

Very impressed with this one, they really did a great job and it may be even better with the 3.0 firmware update.

Indeed the VX offers a very linear powerband with a huge midband power I didn't expected as I haven't found that kind of feel in any esc i've tried so far.
may be due to proprietary fets (at least this one is not a rebranded esc).

Can't wait to try the new TX motors too.
