Ok!!!! Didn't mean to offend you or sound like I was putting down your piloting skills, and you didn't mention dropping the tx before!! But my advice is still the same. For the room you have to fly in, you would be better off with a Super Cub. The J-3/Decathalon is not as good in the wind and is more fragile. But since you already have some parts, you might look at a PnP J-3 or Decathalon as an economic choice! I have 3 parkzone j-3 bl's and have some interference problems in my area on channel 1. I changed the rx/tx in my channel 1 j-3 to a 72mhz tx/rx from a Stryker. Servo's and everthing else are compatible, just dropped the rx right in, no problems. I bought the rx/tx on e-bay for $20, which is cheaper than you could by a stock replacement tx! Lots of people who buy T-28's, Typhoons, and Strykers, are selling the radios cheap on e-bay because they are using better radios like Futaba which they already own or they are changing to spectrum radios. You also might find another J-3 on e-bay cheaper than you could buy a new PnP. Just something to consider. Wish you luck, keep us posted!!!
