well 1st the sound of course was mixed in post edited, from another sound source. the electronics and all basic parts are from the FX070c, I just removed all the wiring as it was not heavy enough gauged wire, so replaced with a bigger gauged wire, tricky to solder on, but got it done, doubled the anti-vibration foam that the receive board sits on, removed the cheap stock heat sink, installed one for a 390 motor from a P979 truck, beefed up the interior with light weight aluminium shafts, used my famous "fix it all" super glue that is tough as normal super glue but drys like rubber cement. I used those on the pods and landing skids to beef them up for any hard landings. added fron and tail LED lights, using a 1300mah 3 cell yellow zippy battery and a voltage alarm,remounted the battery more forward, made the from cockpit cover removable with velcro for esay battery access.
