Ordered flishrc cobra. Communication was great. Ordered larger batteries but they were the wrong size. Olly shipped the right batteries and gave a refund for the difference I paid. Couldn't ask for more. Thanks for the help with the order.

The seller knew I was after one and very kindly informed me when they came back into stock so now have a Flywing Bell 206. Fantastic bit of kit. Well worth the wait.
