If you build lite and keep the aircraft lite it will fly like a dream. Usually people use payloads:- Cameras:- a GoPro HeroHD2 or HD3 , a Panasonic GH2/GH3 or Nex5/Nex7 or a NikonV1/J1 camera. SLR cameras can be flown but their large heavy mirror designs are irrelavant in the air when the pilot is actually on the ground not using the mirror box. The new generation of mirrorless cameras such as the GH2/GH3 and Nex5/Nex7 which produce Pro quality video as minimal risk - a 1-3kg multicopter has far less energy, less noise and risk to person and property on the ground, compared to a 6-9kg copter carrying a DSLR. In making your Airframe its recommended using a Quad as a trainer aircraft - followed by a 2nd aircraft later - a six engine Multicopter like Vampire or YSiix to conduct professional photography as this offers single engine redundancy - should an engine fail then a six engine multicopter can fly on the remain 5 engines. A light fpv quad is 650g and a larger Scarab Quad is 1350g with LiPo and mirrorless camera onboard. Above this weight we recommend Vampire and YSiixKopota for better payload. If you are a beginner you CANNOT jump past the training phase - you must start with a SMALL QUAD TRAINER
The MultiWiicopter team commandments - We wrote this list in RC blood - this is not some cheap cut-n-paste - read and pilot-up - multicopter are complex aircraft not toys ....
TO KNOW:-
-Balance all Motors - dynamic - you must do this step.
-Balance all Props - static on a prop balancer and also dynamic by running them to check vibration and eliminate it - if you have not balanced your props you are an ameatuer hack - sorrrrry - but it's true - you will create a raft of problems for your IMU and your video productions - just do it and accept that this is part of multicopter culture and setup - Do not bullshit yourself.
-Check all Prop adapter collets and shafts are true - not bent - check each prop & motor combos are
