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.

About this product
PRECISION AEROBATICS QUANTUM EVO 35 PRO HV-SBEC
PA Quantum EVO line features outstanding quality backed by equally outstanding service since 2003.
The Quantum EVO range has developed over the years and has proven to be reliable and efficient. Unfortunately, however, this success has also attracted companies who have sought to copy our ESCs. Customers are being confused by similar packaging and instruction manual. Some vendors are suggesting these copies are in fact PA Quantum, or produced at our manufacturing facility. Beware of cheap imitations!! Bad ESC = Crashed Plane!

Notes
It is essential to allow good air flow (using the supplied air baffles and installing the gear per the instruction manual) over the motor, ESC and batteries under normal RC hobby use only, otherwise, ESC will heat-up and reach the thermal protection threshold or may damage.
