    Help! Ideal weight deviation range for FT Scratch Builds to get similar performance.

    My scratch build FT Simple Scout AUW is 603 grams with 1300 mAh and 665 grams with 1800 mAh - that is 12% & 24% respectively more than what is mentioned on plans i.e. 535 grams. What is the weight deviation range that can be taken in Flitetest scratch builds to get similar Flight performance as...

    Best Procedure for PID tuning

    I have a naze 32 on a 250 race style quad. Basically I want to get the most out of my PID tuning. I fully understand the P-I-D coefficients and what they do, I'm a mechanical engineer by training, but that doesn't give me the hands on to PID tuning procedure. So how do I start? zero...

    Optimizing flying wing design

    My question is fairly simple: how does one decide on the ideal dimensions and ratios for a flying wing given the target cruising speed and payload or other relevant flight characteristics. For a more conventional aircraft, I feel like I have a fairly good intuition as far as changing the wing...

    2S/3S & Motors?

    I have a motor that takes a 2S and 3S batteries. Will the motor react any differently to a 3S than it does a 2S? Is there a difference in flight time? I realize the 3S has higher voltage but how does that play into the performance of the motor? Thank you
