It's a hardware limitation.

Gesture-Enhanced Single-Touch, also known as "Dual Control", "Gesture Touch" and
often "Dual-Touch" describes the ability of a touchscreen to register certain
two-finger gestures, even though the display hardware does not have full Dual-Touch
capabilities. A very common application is the pinch-to-zoom gesture, which
allows the user to zoom in or out by moving two fingers farther apart or closer
together while touching the display. An important technical reason for the
limitation to Gesture-Enhanced Single-Touch instead of allowing Dual- or
Multi-Touch is the type of sensor hardware in the display. Many touchscreen
technologies obtain two independent measurements per touch to acquire a
2-Dimensional position. Given two distinct touches, however, this returns two
pairs of measurements, which can be combined in two ways, producing an ambiguous
result. Thus, it is not possible to exactly determine the position of two
distinct touches. Still, the average position can be approximated, as well as
the distance between the touches, which suffices for some gesture applications.
This is the reason of the default touch layout.
If your phone is real multitouch you can select a more natural layout of the sticks on the menu option: Multitouch layout

The conversion is made by Leo's RC Simulator for PC. Please, download, install and read the tutorial (In the Import tab).
There is also a addons option on the main menu. This option connects on internet to addons repository. This repository is a free service. Please read the following disclaimer:
Leo's RC Simulator make a heavy use of 3D capabilities. Not every phone has the same 3D power.
The Scenery textures are big (1024 x 1024) and can be a great problem for 3D accelerator.
You can reduce the resolution of the Scenery textures.
Options, Settings, Scenery texture resolution
There are two options. You can send me the addon file (You must have the rights to do it). And I will convert as needed.
You can make you own repository.
