I've had some interesting results with the Cub variants so far - I'm not sure if it's just my lack of expertise or if there is a problem with my setup. For starters I was using FSX + SP2 until two weeks back when I noticed that the Super Cub was developed for Acceleration. So I uninstalled SP2 and installed Acceleration. As far as I'm aware all my other payware aircraft perform as before plus a few prior quirks like door opening and closing now work properly.
However, I do find the Super Cub Extreme versions to be hard to control on the ground and on take-off as others have described. I think I'm beginning to get the hang of things so I guess this is true to life and just my lack of experience?
One thing that is very noticeable is a problem with trimming the Super Cub. It seems very nose heavy and trying to balance weights realistically doesn't help. I can get by using the hardware trim on my CH Flightstick and then fine trimming in FSX but is this correct or is something wrong with my setup?
Any comments appreciated.
Hi Rob,
The only issues with the airfiles were two variables, prop pitch angle and drag coefficient, and I believe the rest is accurate.
Tom had commented on the trim as being a bit slow to react, but as there is no way to control the time constant in trim, it reacts at the speed FSX wants it to.
Super Cubs are light aircraft with big wings, and at light weights would appear to be quite sensitive. Small aircraft like the Super Cubs are not airliners, or even C-172's - they do require 'flying'.
I believe the nose-heaviness with just the pilot on board are accurate, too. These aircraft were designed to be loaded heavily, and landed at low speeds. Loni Habersetzer, of the famed CubDriver videos, actually added 30 lbs of weight at the tail of his aircraft in order to help keep the tail down. I noted the nose heaviness as well, once Tom had done his first tweaks of the airfiles, but I found that at low speeds and higher weights the aircraft was fairly nicelybalanced, and so assumed that was as it should be.
The tail of a Super Cub on the ground is
very light - hence the ability to do brake-stands with ease. If you look at videos of the Super Cubs doing these take-off, you'll see the tails just
jump off the ground (much faster than they seem to do with the Flight Replicas, at times). This also translates to very effective use of propwash to steer the aircraft on the ground - it is indeed very sensitive. Between the very strong brakes of the Super Cubs, and the very light tail with a highly effective prop-wash-over-rudder (which FSX models quite well, unlike the stab and elevator), plus more powerful engines and larger props, you end up with an aircraft that is indeed very sensitive on the ground. If you gun the throttle or taxi too fast, especially in a cross wind, it will have interesting results.

). The Real Air Scout flies like the Cessnas too which was why I was wondering, as I suspected there might be a problem with my install of Acceleration...
