Help with Eve spaceplane troubleshooting

[s_gamer101]

This is my spaceplane. It is supposed to be able to take of from Eve and gain some altitude using its propeller engines that are inside those 3 service bays. (Before anyone is going to say anything about Eve SSTO's, this isn't supposed to be an SSTO, it only has to reach a suborbital trajectory over Eve) Problems:

• When I teleport it to Eve for testing, most of the times the landing gear gets overstressed pretty soon and just explodes before I even accelerate. How do I make my landing gear more reliable?
• For the reason mentioned above, I haven't done a proper test flight so far and therefore I have no idea if those propellers have even nearly enough trust. The current propeller setup is as follows:
  • 6 medium-sized breaking ground rotors, each of them has 8 ducted-fan blades attached to it. The deploy angle will be manually adjusted for optimal trust during the flight
     

Also if you see other stuff that you think is wrong with my design, feel free to tell me

Moved to KSP1 Gameplay Questions, it'll make more sense here..

Wait, where did I post it? I wanted to post it in KSP 1 gameplay questions in the first place

Two comments:  First, add more of them.  Eve is brutal on landing gear, whatever you think you need, you probably need twice as many.

Second, if you're not already doing this- You'll get better results if you mount all landing gears to the center fuselage.  Then you can use the offset tool to move them where you want them.  But the game is much happier if the landing gears are initially mounted to the center fuselage.

You probably have enough thrust, but the only way to know for sure is to test it.  Propellers work amazingly well on Eve.

I found it in KSP2 Gameplay Questions.  It's all good!  I'm assuming you aren't offended that I moved it then.

Okay, I will implement the changes you suggested and do more testing tomorrow

Good luck!  I've had a lot of fun with propellers on Eve, they work great, but require a lot of trial and error.

The only times I've ever managed to recover a crew from Eve was using the BG propellers.  In my case, I used the propellers to do a vertical launch.  I was able to climb straight up to above 15 km using only propellers.

If you get frustrated with the big design, start smaller and gradually make the thing bigger as you get a grip on how aero works on Eve.
