I am making a plane for the fixed gear fighter challenge, and I added a cockpit to the plane, but when I try to fly it, there is too much nose drop, and I cant even lift the nose up slightly! Can you please help?

@jamesPLANESii I tried your idea. It does reduce the wing loading quite a bit. I will try it a bit more, but so far it doesn't really help that much, but I do see a bit of a difference.
@QingyuZhou the problem is that it IS angled.
Rotate the stablizer a bit, like 5 degrees would work.

@jamesPLANESii I meant no offense. I was honestly surprised you didn't mention it. Your Beaver is the first float plane I've seen on here that worked.
Anyway, good luck to you and @Trijets Modifying the horizontal stabs should drastically fix any problems here, whatever the cause.
Ok. That is rather high. Reducing the wing load could help make it fly better. It may not be causing the nose drop, but it will help it. Try doubling up the primary wings. @Trijets
Most of the aircraft I build have fixed landing gear, so don’t you think I’d know a fact or two about fixed landing gear aircraft? I can easily tell that those wheels aren’t anywhere near large enough to pull the nose down to the extent that it can’t even pull up. Maybe I already “know better”. @F104Deathtrap
Apply a tiny bit of rotation with rotation on 1% with the fine tuning tool on the horizontal stabiliser until there’s no nose drop.
@F104Deathtrap yes, i will try that out
@Trijets 32 is fine. The Spitfire had 26, but you've got 2 engines. Did you read my explanation?
@jamesPLANESii 32lbs/2ft
This is just my opinion, without having flown the plane and assuming your wings arent too small or the nose too heavy, but your landing gear is probably pulling the nose down.
The fixed landing gear has drag, and as the plane is pulled forward by the engine, the landing gear is pulled backward by drag, causing the plane to "trip over its feet" so to speak. This happens a lot with float planes and @jamesPLANESii should know better.
There are two ways to improve the situation. Either XML edit each part of the landing gear to have no drag, or enlarge the horizontal stabilizer and angle it leading-edge-downwards by around 1 or 2 degrees. Setting the air foil on the main wings (not the tail) to "flat bottom" may also help.
W8 what is the wing load
I see. Yeah this is probably because of a CoM bug. @BogdanX may be able to help you there. Trust me, none of this is your fault.

@Botfinder ?
Upload a pic to imgur and send a link in the comments @Trijets
@jamesPLANESii how to send pictures
Wait can you show me a picture of it plz @Trijets
@jamesPLANESii it rolled to the symmetric side, so that isn't the problem. I did hear someone say something about dragging the plane out. Perhaps you know anything about this?
@jamesPLANESii okay, I will try that.
It might be that your primary wings are upside down. To test this, make one wing flat bottom, and the other wing symmetric. If the plane rolls towards the flat bottom wing, then the wings are upside down. If the plane rolls towards the symmetric wing, that is not the issue.
@RailfanEthan the CoM and CoL are literally touching, the CoL slightly behind the CoM like it was supposed to be
Move the wings to near the CoM
