T25 R&D Record -Documenting the development of an electric VTOL

T25 R&D Record1 -Electric VTOL load 3-5KG, range 150-200KM

T25 Introduction
T25 is the abbreviation of beta 25KG class VTOL, which adopts a 4+1 power configuration in pursuit of high reliability. v-tail aft thrust layout further enhances cruising efficiency.

The whole machine is composed of aluminum alloy, carbon round tube, carbon square tube, carbon sheet, wood panel parts and EPO foam.

Design parameters:
Wingspan 3.3 m, fuselage length 1.75 m, fuselage height 0.36 m (with carbon fiber tripod)
Wing area: 112 g/dm²
Wing Load: 223 g/dm²
Economic cruise speed: 22m/s(25KG takeoff weight), 20m/s(20KG takeoff weight)
Load bay size: 300×213×135mm (lightweight LiDAR can be carried)
Battery compartment size: 340×220×152mm (can put four 6S30000mah solid state batteries)

Application Scenarios:
1.Carrying 3KG LiDAR mapping
2.As VTOL four types of aircraft teaching training
3.Carrying 3-5KG as a prototype for logistics and transportation.
4.As a research platform with large load and long endurance.

looks really nice. It would be great if camera gimbal can be attached to the nose.



Thank you for your feedback, we will design a similar structure as shown.

@makeflyeasy considering the applications of this aircraft it would be great if you included a cabin for installing a parachute. This would add a layer of safety for the aircraft. The V-tail concept is makes it look cool just like the MFE hero.

I don’t know if at this stage of your R & D it is possible to extend the length of the nose a little bit. This will allow for more battery travel. There were instances where weight had to be put in the nose the hero to balance the aircraft. Considering this is a bigger version of the hero it think there could be similar issues could arrise

Thank you for your reply. Currently there is no parachute design, if you need a parachute you can DIY it yourself later. a parachute that drops downwards can easily get entangled by the propeller, maybe a parachute that pops upwards is needed.

The current nose has increased capacity to hold 4 x 6S 30000mah solid state batteries, and the limit supports 4 x 7S 30000mah solid state batteries.

Referring to the recommended battery and load weights it is easy to level the airplane, if the batteries and loads are too light it will require additional counterweight blocks.

Thanks for the interest, the T25 has had a second generation upgrade and I’m sharing some photos of the test.



















Ok so the V-tail version isn’t being developed any longer?

The V-tail version was changed to the T-tail version. The strength of the foam machine is not high. Our customers mainly use it for surveying and mapping, which requires high stability and reliability, so we finally chose the T-tail structure with the best wind resistance.
