KPQRC Ghost B2 Fighter 950mm Wingspan EPP FPV Delta Wing RC Airplane Fixed Wing KIT
A part of the review has been auto-translated.
This is slow beginner cruise wing, may work for LOS, its not speed build due to soft foam and thin surfaces. But great for beginners or as a cheap one for experiments for 1/3 of the ArWing price._CG is somewhere between 200 and 230mm from the nose with 2mm reflexes - but there is plenty of space to move the battery inside to get it perfect; the distal 30% of wings are soft, control surfaces are too soft and thin for high speeds._Kit weight 240g without taping, 420g with components I have, 450 laminated, 750G total weight with 3s 21700 pack. Im using 2205 2600kv motor with 5152 gemfan prop, thrust is okay, noise is okay, this setup gives me 280g of thrust on 50% throttle on the bench; the same motor with the stock 6 inch prop is extremely noisy but cruises on 25% throttle. I guess 2807 motors with 7-8 inch props will also work. Glue the wings tight and tape the connection to have some rigidity, it wont work well if made portable anyway. There are two fiberglass rods to connect wing and the main body and three (?) for wings, one is probably spare. I also tape the lid each time so it doesnt fly away. Ive rotated the motor mount and cut it to move it a bit back so it has some air to move and Ive made the back of the plane if better shape - this abrupt fuselage ending will cause horrible air movements. Efficiency on maiden was 160mah/km with 30km/h wind, very stable. Default Inav pids work great.
Very durable EPP, the photo is after many crashes. The nose is glued. Travel speed 10 .. 17 m/s, endurance 45 minutes with 3s1p 18650. Hard to take off from hand, it must be thrown straight forward ahead.
