Im happy to announce that we have a successful maiden! I finished the build today by adding the tail and the leading edge extensions. I also added these extra intakes on the front, the real su-27 and most of the derived versions of it had these foldable intake grills to prevent stuff from getting sucked in on taxing, so sure enough Im using those as my advantage. Static thrust got increased by 200g. I planned to use 4 4s drone batteries at once since I have a lot of them but I kinda messed up the cg so Im using only 3. At least the wing loading is lower. Should have placed the fans 50 mm or so further back. Anyways, it flew really beautifully, feels really gentle in the air and it has a lot of power. A bummer it has only a flight time of about 2-2,5 minutes. I was supposed to fly two flights but unfortunately on the landing one of the pushrods got ripped out by the grass. Really easy fix though. Now the next step is to throw some paint and decals on this thing.
Oh and btw those mosquitoes really sucked...
Here are some numbers:
mass 1950g
thrust static 2350g at 120a about
wingspan:1010 mm (scale 1:14,5)
length: 1450 mm
edfs:12 blade
Batteries: 3x 4s 1,4ah 45c
esc: 2x hobbywing 80a
Servos: 2x emax es09md
Man, you are really good at this designing and building stuff. Great work!!! That thing flys so well!!!
