No, quite the opposite. Flaps increase the local camber at the root area of the wing, which in turn increase the local angle of attack. Meanwhile the wingtip is at a lower angle of attack than the root, making tips stalling much less likely. The slight downside is that flaps also increase drag, albeit take off flap of circa 15% amounts to only a slight increase. Nontheless, heaving the nose up too high on the climb out is slightly more likely to induce a stall since the model will decelerate a little more quickly than when clean. However, this is only likely to be noticable on a marginally powered model.
The prevoius advice is good. Use flaps and be careful of the elevator. Allow the speed to build up and clean the gear away quickly.
Also, the rudder has a part to play in scale models. smooth coordinated turns are unlikely to cause a tip stall whilst slipping or skidding turns can and do lead to tip stalls.
I hope this helps,
