The results vary from plane to plane, but when I make a plane larger, say, by 500%, so it's around a 35' span (just graphically, physics- wise, it's still "stock"), the plane jumps around on the ground like it's, for lack of a better term, on hydros. It'll jump and bounce and then break and fly off into the distance. I have a 3.4Ghz P4 processor and 3GB of RAM. I forget what video card I have, but it does the same thing on a friends laptop with a completely different hardware setup.

Another issue is on the turbine jets, if I give them upwards of 80 lbs. of thrust, they go VERY fast for about half a second, and then the model just shuts off- the turbine quits, and I have no flight controls. It's not out of range, because I have that feature turned off, and it's only 1000' or so away from me when this happens. If I'm very careful with the throttle, it'll fly fine, but once I advance it past a certain point, the model will rapidly accellerate, and then everything on the plane- flight controls and engine- go dead, and the model just slowly floats to the ground as if in a flat spin, acting like the aero surfaces aren't affected by wind at all.

These are two minor annoyances in what is otherwise a fantastic flight sim. The last RC simulator I had was the OLD Dave Brown simulator from the early '90's that ran in DOS on my 286 Kaypro.

It would probably have been smarter if KnifeEdge hadn't given the enlarging function out to the public. You've not mentioned the fact that just enlarging does not increase the strength of anything. When they're larger without being proportionally stronger, they simply break when stressed.

You're lucky the wings didn't fall off before the engine quit.

There appear to be a number of things that you have to do when you use that enlarge function. I'd suggest you go to the KnifeEdge site to their forums and ask what all those things are.

Well, I understand the strenth issue, and I'm not changing the physics size... just the graphics representation. It's on the main menu once you open the edit window, where it shows the scale in %. The wireframe is still the same size, the models still "weigh" the same as their normal size, and on the occasion that I can get them off the ground, they don't break apart in the air. I have also tried increasing the physical strength to 1500, and that still doesn't cure the problem- jumping around while sitting on the ground. They only break when they jump upwards of 30' straight up and come down and break the gear or a tail feather.

Why would it have been smarter for the public not to have the enlarging function?
