You've pulled off a real beauty here. In a way, I had a sense of involvement in this project. You are right, I'm going to miss this build thread. It was something that I used to look forward to every day.

Waiting for the maiden Video in December! Thumbs Up
thanks VC! I was a lil busy:) Yes you've probably been involved in the making bro! thanks again.
looking forward to build a EDF next, just waiting and searching for plans, I like the F15, remember you sent me a huge F15 plan? I want to make that one, but want to convert it to EDF Sad hard job on that one..If you happen to have any EDF plans please send me some Smiley

This is one of the best builds ever in this forum.. cheers!

By any chance, did you replace the tail surfaces? They look thinner than the previous pics

Noted Sir Thumbs Up
In the meantime, I will start with another jet, this time am thinking of a EDF, as I have one EDF with me, but there's a problem, theres no number, no ident. sticker on the motor. Sad
How do I know the Wattage of the motor? a watt meter?

One of the simplest and rough method of measuring the KV is like this:

1, Run the motor at a known (low) voltage. Say around 6 - 7V. (You need a multimeter)
2, Measure the RPM of the motor. (You need a tacho)

As you know, KV of a motor is nothing but RPM/Volt.. You know both the voltage and the RPM of the motor.. so, it should be fairly straight forward to calculate the KV. Note that this is NOT the accurate method but should be fine for our RC use.

Oooohh..hold on. I just missed something.

The RPM should be measured at NO load..meaning no prop. This is dangerous (at 6V) and may burn out the motor, unless you are using very low voltage at around 1 - 2V.. I am not sure if the ESC will power up in that voltage range.. So, I guess you are back to square one.

I am sure someone might know to do it.

If I were you, I would do the RPM measurement with a low pitch prop and use a margin of 20% - 30% on the measured RPM... in any case the whole experiment is just an approximation.
