Align 3G Programmable Flybarless System on 450 Sport?
<div style="margin: 0in 0in 0pt">Exact placement/attachment of the 3G Control unit on a T-Rex 450 Sport is the question.</div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt">Aside from the trivial Rotor Head replacement, the Align 3G FBL system consists of a Sensor and a Control Unit which are to replace the GP780 stock Gyro. These components are of the following dimensions:</div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt">GP780 Gyro: 26x25x11mm</div><div style="margin: 0in 0in 0pt">Control box: 42x26.5x14.5mm
Sensor: 22.3x21.7x14mm</div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt">For T-Rex 450, there are two versions of 3G system, H45110 black metal for 450 PRO and H45109 blue metal, but the brains are the same for all. Both are supposed to fit any T-Rex 450 version, from SE to V3 and PRO. After a lot of search online, I could not find a manual for the H45109 version; however, there exist a manual for H45110 which is specific to the 450PRO version of this upgrade.</div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt">It shows the 3G sensor placed exactly where the GP780 Gyro normally sits. It also shows the bigger 3G control unit attached to the right hind side where the tail boom comes in.</div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt">While the small sensor having comparable dimensions to the Gyro can simply replace the GP780 directly on any T-Rex 450, the larger Control box is a different story. The arrangement of servos which are mostly inside the frame on the 450 PRO allows the big control box to find a place on the body where that is not the case on 450 Sport. Is it true that the dimensions of the control box are just too large to fit inside the sport’s frame, and the servos attached on the outside just don’t leave 42mm X 26.5mm room for the control unit? Or does it in fact perfectly fit in the frame, under the boom where the tail servo sits in PRO and is vacated since that servo is conveniently attached to the boom on 450 Sport!!!</div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt">Any insights?</div><div style="margin: 0in 0in 0pt"></div>
