Props

[SteveMcK]

Hi Guys Im new to the forum.
Just cut me teeth with a Quattro-X and decided Im going to jump in and build a Hex.

Ive done a good bit of hardware reading and i';ve built with the following
Tarrot 680 Pro
Tarot 4006 620 motors
30A Hobbywing ESC
with
Naza -M lite +GPS and DR8-II rec

My question is (as I know nothing about props) what props should I go for? And what Battery?

Thanks  in advance

Here is a similar build to take a look at. The math for working it out is individual motor thrust times number of motors divided by 2.

So if each motor has 1kg of thrust your full load could be 3kg

Right, but what he wants to know is what props he needs for his proposed rig. What you mean (I assume) is that starting with an estimate of 3kg AUW (all up weight, inc. drive, batteries, etc) for his rig then he will need a prop that gives him hover capacity for a 3kg rig at around 50% throttle without dragging out of the battery enough amperage to illuminate Vegas for the next 40 years. What is needed, then, is an idea of which prop will best achieve this efficiently (i.e. resulting in decent flight times) for the setup proposed.
I don';t know what Tarot suggest for the 4006';s but there should be a spec sheet available providing stats for suggested prop sizes. In addition it is worth plugging the specs into eCalc (available online) and playing around with different prop sizes both in terms of length and pitch to see what figures you might expect to achieve.

You shouldn';t be building a hex without knowing the basics

Give a man a fish....... And all

Get a good estimate of the total weight of the craft 600g plus for a battery and then you can start looking at the right props for your setup, using the info supplied by Dr Phibes

Tarot TL2829 1355 carbon fibre props are what Tarot recommend for the 680 pro with 4006 motors. These are what I have, but not tested yet as my build is still in progress.......

By the way, these were perfectly balanced, straight out of the box.

Blimey keep it simple for the poor chap !!! 12" props i.e 1255 carbon, and i would prob use 5000 mah 4s batts for the setup you describe !!! Hope this helps...
