NOTICE
This is an electronic duplicate of the Thunder Tiger Manual for the Raptor 50 V2 kit. In contrast
with the Raptor 30 manuals, a Raptor 50 manual has never been made available in electronic
form by Thunder Tiger. Therefore this manual was constructed partly by scanning in parts and by
manually creating the pages, and partly by copying and modifying the Raptor 30 V2 manual. I did
avery careful job in duplicating the manual, but of course I can not assume responsibility in case
of errors.
The duplicate has been kept as close as possible to the original manual, but at numerous places
errors and typos were corrected. At many places the English text was improved, as well as the
layout. Some part numbers have been corrected. A few sentences where correction would need
more than changing a few words were left unchanged.
The front page has been recreated in color, where the original manual is all black and white. A
colored front page is so much more inviting!
I hope you enjoy the use of this electronic manual.

INTRODUCTION
Congratulations on your purchase of the Thunder Tiger Raptor 50 V2 helicopter. This model was
designed and engineered by the World-renowned Mr. Shgetada Taya. It combines elements of
his previously successful designs with today's advanced technologies.
Raptor 50: the best 50 class 3-D helicopter is now even better! The Raptor 50 V2 is the
cumulating result from all customers' feedback and tremendous research and development effort
by the Thunder Tiger design team. The Raptor 50 V2 is more rugged and has even better flying
performance than the original successful Raptor 50. The Raptor 50 V2 has the best power-to-
weight ratio of any 50 class helicopter on the market. Buckle your seatbelt and get ready for
incredibly fast accelerations and climb rate. With the new main rotor, 3-D pilots will enjoy
executing crisp maneuvers like Climbing Tic-Toc, Chaos, Death Spirals, and any radical
maneuver that pilots can dream of. Key new features include stronger mainframes, bigger fuel
tank, reinforced pitch control arm, new main rotor with 6 mm spindle and bigger radial and thrust
bearings, and a fresh new look body. The V2 includes a constant drive auto rotation gear for
doing aerobatics during autorotation. Beginners and advanced 3-D fliers will be very impressed
with the new Raptor 50 V2.
