Como distribuidores oficiales de Aling acabamos de recivir este aviso que tenemos que publicar, para los ususarios del T-Rex 600.
Dear customer,
We have discovered a critical safety issue on the T-Rex 600 and hereby issue this safety bulletin.
Abnormal fracture line has been discovered on T-Rex 600 main blade grips during post-flight
inspection.
With the T-Rex 600 mass produced and readily available, more variation in setups and power combinations are
attempted by pilots in real life situations. We have unexpectedly discovered some abnormal fracture lines on
blade grips in certain instances. Upon further investigation at microscopic level, our technical department has
found the blade grip’s structure integrity to decrease dramatically with the presence of these fracture lines.
Flying with these fractures at high headspeed with 11T pinion may lead to breakage of blade grip. This problem
was not detected during our long-term longevity and stress tests since the tests were done with stock power
setups.
We suspect the cause of these fracture lines may be due to over tightening the M4 blade bolt, or stress around
the bolt’s hole from crash impact. Flying high power setup with these fracture is extremely dangerous, at worse
case could result in midair detachment of blade grips.
To improve on structural integrity of these grips, we have developed and tested a new design with thicker area.
The new grips greatly increase the overall rigidity and safety of the head. We are sending these New grips to
you (2 new main grips, 2 M4x27 blade bolts per kit) and please return all the parts H60003 to replace.
Feel free to contact us with any questions.
The original holder is on the left side of below photo. New thicker holder is on the right side of the photo.
We sincerely apologize not catching this issue during product testing, and the inconvenience this may have
caused our fellow flyers. Your understanding and continued support is greatly appreciated.
We recommend that all T-Rex 600 be grounded regardless of the power system being used. For safety reasons
do not fly the helicopter until the blade grips have been replaced with new design.
Best regards,
Wendy Huang
