Overview
The FMS 1400mm T28 is going to get its fourth remarkable upgrade after it was launched three years
ago. The 1400mm T28 V4 is coming!
No matter whether you had an FMS T28 or not before, the coming V4 is full of surprises. First of all, the
foam ratio has been upgraded from EPO 40 to the lighter and larger EPO 52, which alleviates the
airplane's weight, without weakening the airplane. Moreover, the original oil paint which has an
unavoidable negative side effect of corrosion has been replaced by the latest environmental water-based
paint.
Let’s take a look at more upgrades below. The latest FMS multi-connector is also used for V4, which
makes the assembly easy and simple while leaving the wires orderly and user-friendly. The 1400mm T28
V4 adopts the new design of ball linkage to remove the clearance and hit an accurate flight. The updated
4258 motor drives the power and speed around 30% higher. In addition, it could work with 4S, 5S, and 6S
batteries to satisfy different customer requirements. Both front and rear landing gears are metal, with a
shock absorption function for hard landings. In terms of construction and performance, the 1400mm T28
V4 is totally different to the old versions. It is certain that the latest version greatly enhances flight appeal.
Don't miss out on this thrilling experience.
