Dany,

I've flown the X-tremejets and the FB Rafales. They are nearly identical except for a few differences in the way the hatches attach, paint finish and steering (gear). What I've experienced is that you can make a good landing in a short distance if you manage the throttle well through the landing pattern. You can make the landings on your short airstrip no problem given that your approach is at the right angle of attack and speed. The external tanks will require you to relearn the pattern and approach with the throttle at a different position on the transmitter. Fortunately the Rafale airframe is so forgiving in terms of stall characteristics that you can "work" the landing over the runway with the throttle at idle and slow it down if you come in to fast. As for your take-offs, I think your airstrip is too short for a scale take-off. You’re likely going to have to leap off the runway by the time you reach the end. If the nose wheel steering is perfectly trimmed and can go full throttle from the start then you are in good shape. I typically do a slow ground roll to establish good tracking straight down the runway and then go full throttle for the takeoff about (122-152 meters) 400-500 feet down the runway.
