i would definatly recommend changing the Jumper settings if you have your co-ordination skills sorted
all the Jumper is doing is electronically compensating the elevator in a turn,
if you have been flying a while i am sure you will be able so feed in a bit of Up during a turn,
question 2 i cant help you with unfortunatly [&o]
question 3 the Stryker is fast even in Stock form and you have to learn a whole new launching proceedure,
it is Great fun to fly, and as it has 2 elevon rates controlled by the Tx i would imagine you could fly it on low rates untill you are comfortable with it,
i always suggest trying it on FMS as they have a good F27 available and its Free
