After 3-axis gyro debuted, T-REX600E PRO is the first promoted type, it has many latest designs, as expectation, these designs will be used to Align¡¦s entire series of helicopter, and come out many V2 versions in a short time. 700E V2, 700E F3C V2, 550e V2, 450PRO V2 have come out before the article published, now we are going to introduce the upgrade of T-RECX700E F3C V2 and V1.
There is no big difference between 700E F3C V1 and V2 from the above two pictures. The key point is the colored painting of canopy which is leading visual impression does not change, and so as the vertical fin. Therefore, they are almost the same at the first impression.
Rotor HeadThe rotor head changes a lot, the adjustability of V2 is better than V1, and it is easy to configure the rotor head to the characteristics to your own preference

700E F3C V1 
The differences between V2 rotor head and 700 New Designed Main Rotor Head (HN7114)Align had released 700 New Designed Main Rotor Head (HN7114) for 700E the other day, but V2 rotor head has slight differences, which is the direction of the washout base and the SF mixing arm is opposite. Because the previous long linkage rod of 700 New Designed Main Rotor Head (HN7114) is easy to make linkage rods interfere with the screws of SF mixing arm if the angle of cyclic is too big at negative pitch. Now the problem of interfering has been solved, therefore, the range of configuring of V2 will not be limited anymore.

700E New Designed Main rotor Head 
Battery MountV2 is different from 700E. V2 continues to use the same design as 600E PRO, and the material is aluminum alloy.
V2 V1 
Carbon Tail Control RodAlign started to use carbon tail control rod from 700E F3C V1in order to less the vibration than steel rod, and provide precisely tail control.
V2 also use carbon tail control rod, but the difference is the amount of the tail control guide, V1 has two, while V2 has one.
It is an improvement for author, less friction between tail servo and tail rotor control arm is better. The author has a 700E F3C V1, and he/she found that there are two guides added between tail servo and tail rotor control arm. However, the two guides are not high as each other, so these two points cannot link to a line. The tail rotor is easy to flutter because the friction is too much. After the author fixes and adjusts the guides, the problem of fluttering has improved. V2 use one tail control guide and it can let the friction reduce to the minimum.

V1 
Tail BoxV2 used brand-new tail box, the frame became thicker, and the quality became better, also, it is easier to take apart. Besides, there are abrasion-resistant pads in the port of linkage ball on tail pitch slider; it makes the metal linkage ball more durable.

V1 
FrameFrom the real product of 700E V2, the frame has little difference, which is that, the position of fixing Velcro blow the frame became double-hole. Also, the carbon fiber frame is bigger, so the structure will be better than V1.
Is the frame of 700E F3C V2 the same as 700E V2? The author thinks that the formal sale version may be the same.

These are the differences between T-REX 700E F3C V1 and V2. The other parts such as M1 slant main gear, mental elevator servo mount, mental rudder mount, carbon flybar paddle, F3C main blade, and MX700/470KV brushless motor, etc are totally the same.
