Re: "im building a kadet seniorita and was wondering if the steerable nose wheel is a necessity or not? "< not if you remove it and convert the plane to a tail dragger which is better on grass runways anyway, no nose gear to get bent!
Re: "where i will be flying it wont really pose any need for taxiing around, it will be point it towards the wind and open the throttle. "< sounds good in theory but in practice there is always something pushing against the wheels to move the plane in a different direction than you planned. You will probably need around 50' for the plane to reach takeoff speed and a lot can happen in that distance.
Re: "although if i dont need one, i was also thinking of rigging the cable up so i could just hook the cable up to the servo if i decide to use it."< if you have the cable any way why not hook it up?!? Btw, when you do hook it up, set it up so that the wheel will only move about 1/8" to 1/4" in each direction. It doesn't look like much but trust me, its all you need! Any more than that and the plane gets too touchy to control at higher speeds. [8D]
