Flyer 2.4 meter Motor Glider.
The Release Candidate #1 was developed based on the 1.5M prototype which first flew in November of 2018. It features a longer thin profile slightly under-cambered wing and a V-Tail. With an all up weight of approximately 2.25 Kg (5 lbs), including a 450 watts power system and 2200 mHa LiPo battery.
Following the 1.5M prototype, more than 200 design changes were incorporated in the design to improve printablility and assembly of the model.
Flyer 1.5meter Motor Glider.
The prototype developed in 2018 first flew in November of that year. It accumulated 40 flights over the next 5 months. The aircraft proved to be a stable platform with adequate control authority over a broad flight envelope. The short under-cambered airfoil allowed long power-off glides of approximately 10 to 1.
Plank 1M Pusher. The goal of the project is an aircraft that is capable of substantiating flight for more than 30 minutes with a 2-cell 18650 lithium-ion battery pack The prototype which is under development since mid-2018, completed initial taxi tests in early 2019. The power system proved inadequate to propel both the aircraft and its launching dolly on a grass runway. The model is being re-engineered to incorporate a tricycle landing gear system.
