Since I'm on my iPad mini,I can't have mods.So the fine tuner isn't available to me.And I've been having issues with the size of car wheels in sp.The main issues happen when I'm building an aircraft that is a little smaller than I accounted for.So when I go to slap some car wheels as the prime gear on,I size them to the absolute smallest size available,and they're still to big.I've started using spherical balls as the tailwheel,which works quite nicely.But I cant use them for prime gear,because the tailwheel is so small,you don't think about it being spherical.And I thought it would be nice if we could simply have a larger sizing scale than we do currently.It's just a simple suggestion that would be very helpful.But it isn't necessarily a necessity.So I hope you take this into at least some consideration.
