Hmm, intersecting runways in the Tampa area, sounds like Bay City Flyers. Thats the only field that has intersecting runways I am aware of. There are several more clubs in the area with many more instructors. CAN-AM, West pasco, SPARKS, TRAC, Triple Creek, all are in the Tampa vicinity. If you bring your plane to TRAC, I am sure someone would be happy to help you get your plane set up at no charge. There is still a lot of people that havent realized the advantages of larger electric aircraft, unfortunately, those are at times instructors and they convey their opinions to new people. If a person wants to learn to fly RC airplanes, their best bet in my opinion is electric power. The electrics are not so troublesome as the glow engines. It can be very frustrating for a student who wants to fly to instead spend his time with starters, glow plugs, tuning engines, glow drivers and cleaning fuel goo from their planes. I learned to fly with a glow powered trainer but if the availibility of good electric power components and prices had been what they are now, electric would have been much better. Most people get into this hobby to fly, not to become engine tuning experts. If a person prefers the sound and smell of glow fuel engines, then thats the direction they should go. You have to decide for yourself what you want. As far as using the rudder, I have never heard anyone say not to use it when learning. I can understand the first couple flights having a student use elevator and ailerons just to begin learning the basic concepts of moving the aircraft in the air but rudder has to be part of the training at an early stage or the first crash will come much sooner once the student starts to learn to land especially. In this hobby as with life, there is no shortage of opinions but there is a real shortage of good advice at times. Good luck.
