A quad I built for indoor flying. Designing cam holder/canopy was the most challenging and satisfying part. As usual I made it from high impact polystyrene bent using hot air. Camera is fixed in place by putting its lens between two pieces of adhesive foam glued to the inside walls of the canopy. 29 grams dry + lipo. I fly it on 1S HV 450mah Gaoneng batteries. Had to increase minimum power to make motors spin on arming. Maximum cell voltage also needed to be increased to 4.5 in BF. Otherwise BF considers HV lipo to be a 2 cell battery with extremely low voltage and gives voltage alerts even though battery is fully charged to 4.35V. Warning and minimum cell voltages needed to be lowered in BF too not to have low voltage alerts flashing right after take off. I didn't know what to do until I saw Nick Burns' video. Thank you Nick!:)
