Limited time/condition Offer Exchange / Upgrade
This is a special offer for existing registered WookongM owners to upgrade/exchange an v1 IMU for >5kg drone (v1 IMU is worth USD480) for the A2M Metal style "Wookong" (later known as an A2M then A2 IMU- same item different logo) V2 IMU (v2 A2 IMU is worth USD720)
Operating at or near this max legal weight can amplify out of balance props/motors, increased resonance and out of track props (all user errors in set-up) causing IMU to receive junk data - so this new IMU v2 has been designed to further resist issues . If your drone is well balanced and your operating safely below the max weight of 7.0kg then this upgrade is NOT necessary.
The main difference is a) is made from metal which does not allow sunlight-flicker to effect the barometer in some sun/shade runs b) has 2 side mounted static ports to provide BARO sensing free form high speed pressure in-equality from a single port. From our tests we did not notice any difference in flight characteristics
great for a Post-crash IMU fix.
Bottom line for >5kg - is if you don't balance all motors and props and remove ALL vibration - this IMU will NOT help you, and the entire process will be a waste of time. You must balance ALL motors and props and then do this upgrade/exchange
1. ONLY valid for WookongM
2. Order this exchange/upgrade
3. Return your v1 IMU to us - signature delivery
4. When we receive the original IMU from you un-damaged - We will then Ship an exchange v2 IMU to you.
Note : in fairness this is an exchange program - If your v1 IMU - marked with your name and RMA number - does not arrive in a reasonable amount of time the order will be cancelled & fully refunded and the v2 offered to the next person.
