The Monster Cub!

Gang,

Possibly as a result of making the J-3C more powerful and then back to 65 HP, when I slowly apply power at take-off, the wings hit the runway and it runs off the runway. I still don't have AirEd, but I did change one aircraft.cfg roll setting from 1.0 to 0.3. Like I said I am back to 65 HP and I just looked at the Wikipedia article on this particular engine. The displacements are close and my compression ratio is 6.5:1. Now what happens at take off is a strong yaw to port which is controllable by application of full opposite rudder.

I don't remember the J-3 being a bear to get off the ground when I started flying it although landings always resulted in a wing hitting the runway. Thoughts?

I printed the Wikipedia article and will compare what it says about the engine to my configuration file.

Thanks,

Sean

To keep it simple, ALWAYS back up your files before you start wrenching on them. :)

I'm not sure about FS9, but FS5-FS2002 were not coded for tail draggers (not counting the Pup which is a whole 'nother animal). In some ways, its as if tail draggers violate the laws of FS's universe, or at least it's dynamics.

One thing you could try is to dive into the "gear and scrape" section and set the mains farther apart. You might also try setting the tail wheel farther back (or a combination of both). This is cheating but its easier than goofing with the horsepower and prop.

I'm not sure if this is of any help, I remember seeing it a while ago, it helps the steering of a tail dragger:

Actually, the mysterious 'backup' on my desktop had a 7.5:1 compression ratio (should be 6.5:1). I have FS9 on two machines and I can't remember if I left the other one alone. I'll check that tonight.

I think I could re-install to a different directory, maybe a thumb drive if I had to.

However, the monster cub still wants to go off the left side of the runway after the tail lifts up.

Best,

Sean

"404". What was it back when it was online?

Thanks,

Look at this thread, I got it to activate from there but the link won't work if I post it in a post, don't know why:

The Cub FDEs have been 'done' before. No need to re-invent the wheel. Here go:
