@otayahiromo8211 I use the Colour Editor mod from the Simpleplanes Mod page. all you do is click download and when you start the game next, you'll find it in the Mod section. I don't think it works if you download through the steam "Shift+Tab" menu though. @TheHawk119 In the fix version I made, I did the opposite to solve that issue by raising the CoM up to be level with the engine. I also angled the engine downward to line up with the CoM more. It works but it looks weird when you roll.

@TheHawk119 thank you for your advice!

If the engine is on top it naturally thrusts the plane forwards in a downwards direction so if it is put underneath the plane it will push it upwards. Hope this helps a bit. (I recommend hiding a “real” engine inside a fuselage or something similar).

@greasytortle I got ot, thank you so much! You made cockpit glass mirror, but I dont know how to do it. Did you use xmL?(I dont use other mods)

The problem of the nose dropping so fast Is that naturally they would do that but your center of mass is too fair towards accelerating the rate of the decline of the nose of the aircraft

@otayahiromo8211 I made an unlisted version with some fixes. Here you go:

Very nice replica . Great job .

@otayahiromo8211 I already fixed the landing gear. I'm trying to work on the engine so it doesn't constantly push the plane nose down. are you alright with that?

@greasytortle oh really? thanks!

@otayahiromo8211 I can help you with the landing gears if you like.

much too long

@OndrejNedoma thanks, but it is not complete.
