For the purpose of cross wind take off, it’s very hard to keep your rubber slider over and at the same time retract gear with out letting go either the rudder slider or using your other hand that’s on the throttle to keep the nose from whipping over.
It is alittle unrealistic but for the sake of the mobile device.
Well in real life the co-pilot would raise the gear lever, unlike in IF where there is only you to do it all. I personally have never found a reason to need this feature, but like I said, it would be like having a co-pilot which technically would make it more realistic in a way. If it were to be added, I would definitely want it to be optional.
Also consider decoupling your ailerons from the rudder whilst on the ground. If your accelerometer on your device is super sensitive you may be fighting on take off! Setting switch in General ‘Auto-Coordination’. Wow the spell check gets me every time.
