What is interesting is that we have little to no emails to our help desk on issues with the P51. If people don't contact us through the appropriate channels, we cannot help. Personally I fly the P51D quite a bit and have no problems flying it. Takeoffs are challenging, as they should be, but not too difficult if the tailwheel lock is applied properly and throttle introduced sensibly. From what we have seen with the customers that have contacted us, these two areas are responsible for most mishaps. Jamming the throttle full open will result in poor ground roll behaviour, due to torque. Not applying the tailwheel lock with the flight stick will result in unusual behaviour. We have also discovered that some customers' system setups and peripherals setups can contribute to difficult handling. There is nothing wrong with our P51D but if you have an issue you really care about, then contact us with as much information on your system etc. as possible. Also has anybody ever wondered if maybe these other "mods" etc. might be providing a conflict?
