I find nose up trim helps a lot on take-off in all aircraft and that includes the JF Arrows. There is a tendency to wheel barrow that in real life can be compensated by light back stick but in game can only be countered with nose up trim.
In terms of landings in crosswinds they seem more manageable in the Arrows if you do a slipping power on approach rather than crabbing.
In real life, crabbing is not really recommended in high crosswinds for very light aircraft anyway - it may be easier to maintain the centreline but because there is no momentum in the direction of travel the transition when you yaw can put a lot of sideload on the undercarriage and tires. ( Airliners are the opposite, a slipping approach risks a pod strike but crabbing is fine as the aircraft has enough momentum to continue in the direction it was pointing on short final no matter how you yaw it. )
