Hello everyone... I am new to this fantastic world of Gopro and like many other I am considering getting a Karma drone. So before spending a lot of money on the drone I started reading and watching reviews and fairly soon it became clear to me that there is something called horizon tilt issues and after some thoughts I came up with the following...I believe that the Karma drone and the integrated Karma grip use some form of gyro in order to keep its position in space and one of the things you learn in flight school (I am an airliner pilot) is that gyros like many other systems have drawbacks and limitations. I do not know exactly what kind of gyro Gopro use but with regards to the price it certainly is not one made out of lasers i.e it is fairly simply in design. Without getting too much into detail there is something called "Gyroscopic wander", as the rigidity of the gyro system want to keep the spin axis fixed in space, the gyro will either "drift" or "topple". Drift is when the spin axis turns in the earth horizontal plane and topple is when the axis tilts in any earth vertical plane. Furthermore there is something called "real wander" and that is when the gyro axis is not staying in its position in space mainly due to imperfections of the gyro.
But the gyro also appears to drift due to the fact that the gyro tries to keep its position in space as the earth rotates. This is a function of latitude, Drift=15 x sin latitude/h. So in Sweden where I live a gyro is drifting:
15 x sin 58/h Equals approximately 13 degrees/hour this means that if you have a directional gyro in your sports aircraft (airliners use more stable platforms) the gyro will drift about 13 degrees in the example above and the pilot has to calibrate the gyro every now and then, for example 4 times an hour in order to fly in the right direction. So with the above in mind, why does a Karma gyro drift or wander or both? is it due to imperfections of the system, yes very like, is it a gyro like the one I just described and has to be calibrated prior to each flight with the drone, also very likely.
More reading on various forums on the internet seem to point out the horizon tilt issue not only on Gopro but a also on the competitors gimbles. I think in this price-range we are focusing on the tilt is a fact that we need to address and if I had a drone I would certainly calibrate it prior to each flight in order to get the most of it.
Anyone else who have a similar theory?
