hi I've just bought my first drone the spark and love it. Just added crystal sky 5.5 and the mount but find each time I turn it all on no matter which sequence it's turned on it won't connect the heli unless I disconnect the otg cable from the RC then hey presto. Tricky pulling and replugging the otg once the CS is attached and stressing the cable. Any suggestions ? My first post here , sure first of many ! Thanks
