I have done Dynamic Soaring in over 55mph, and quad flying in over 25mph with the right equipment.

Is weight *that* important to battery life...

Hi Everyone,

I have fitted two 5000mah batteries to my big quad, and now, it weighs a ton. I have identified a few areas where I can strip weight, and I recon I can reduce its weight by about 400g (at the moment its 3.3kg)

What im wondering, will this 400g reduction make a noticeable difference in the flight time or flight behavior?

I have put tennis balls on the quads feet, this stops the legs digging into the grass or knotting up in the grass, which confuses it when it takes off. The balls make a real difference, but they add 250g to the weight. I used to have carbon fibre arms, but changed them to wood as the carbon was so strong in a crash, it caused the chassis to fail. If i change it back to carbon, I can save another 200g or so. I have a few steel pillars that are not necessary, I can either change them for plastic, or take them out all together, saving another 100g or so.

Shall I make these changes, or shall I leave it be, will the increase in battery life be 20 seconds or 5mins?



I always think any weight saved on multi rotors is worth saving, do you need to run with both batteries ? have you tested the flight time with one pack against the flight time with two, I would be interested if your loosing some of the extra capacity because of the extra weight  ~~
