Common Fault and Crash Checklist 

The MCPX although being a fantastic heli does have some common issues, and things you should check before flying your new heli. I also have included an MCPX repair tool kit, which is objects I think are essential to have in your toolbox in the event of an incident.

• Shaking & Vibrations – Check Gromit Mod in Repair Guide
• Loose Motor Screws – Some reports of loose screws from factory, simply remove apply thread lock and replace.
• Rolling – Helicopter rolls violently and without warning, Rebinding is and unconfirmed repair.
• Loose Feathering Shaft Screws – Lateral play in grips, loosing screws in flight, remove and replace with thread lock (Should be less common in newer models.)
• Shaking – Easily fixed with the Gromit Mod (Highlighted in the Repair Guide Section)

Crash Checklist

Ok so we’ve had a little crash, heres our crash guide. Check this things before your proceed again!

• Linkages Check – all linkages are correct and in place without damage! (Often this parts will break instead of causing further damage to the heli)
• Ball Joints – ensure all ball joints and intact.
• Main Gear Position – in the event of a crash the main gear will dis engage, this can easily be realigned and pressed back into mesh. If your heli requires large amounts of collective to lift off then this is probably this issue
• Check Grips – ensure the grips don’t move laterally, this often means that bearing is failing
• Check Tail – Ensure the tail boom is intact, this is an area often broken during a whoopsie! Check it is intact if splits are appearing you can use some CA to prolong the life of it.
• Check Battery – ensure your battery is correctly affixed and intact

These are the main checkpoints, although if you still have further issues flying your heli then there are some further things that could be affecting it.

• Feathering Shaft – this could be bent, an easy way to check this is to remove 1 blade and use a phillips to turn the shaft in a clockwise motion, if the blade stays stationary then its ok, if the blade moves/wobbles in a circular motion then the shaft is bent.
• Clean the wipers on the servo – this is highlighted in the Repair Guide.
• Still having issues? This could either indicate catastrophic failure of a main part, or simply try to rebind this can almost “Reset” the helicopter.
