[far] SSTO climb recovery woes

[endl]

so im guessing you use tac fuel balancer to achieve this? this sounds kind of like a hassle. ill play with the wings and see how much my balance gets thrown out of whack ill probably have to redo the landing gear and rebalance the fuel load to get a better placed COL.

from what i can gather the configuration seems good

You should check your numbers at mach 4+ you will see them change, in some cases drastically.

For most of my space planes I tune them for high speeds, and sacrifice low speed handling.

Here is the graphs and CoM vs CoL for one of my latest projects.

CoM and the COL is close, but not right on top of eachother.

In this one the graph is set to sweep mach, you can see the CL drop off as the craft goes faster, this is because the lift drops as the craft gets faster.

This is the information for the craft at .35 the speed of sound, or about take off speed.

And this is the information for the craft at mach 5, see how everything is still in the green but it changes numbers.

my numbers dont seem to be so bad at mach 5 except for one area, tweaking the wings to be wider doesnt seem to help maybe they should be longer?

ok looks like in the second picture you are checking the AoA of the craft. You want to check that and the Sweep Mach setting. I set the upper to 6 and the number of points to 25. And Max Mach/AoA to 5 in the Sweep Mach.

As for the red number, longer wings may help, perhaps a bit more sweep to them. Fiddle around with them a bit and you will see.

heres the other data, i cant seem to figure out what i need to change i thought i had it then i did some touch ups and it god worse, making the wing longer seems to help the most but ever time i fix the wing flaps the numbers get worse

Try removing the canards or changing the size and angle of the elevators on the rear of the craft.
