These are some articles that i have dug up and found usefull over the years
A guide on how to setup the initial pitch curve on a Mini-Titan E325. It could quite easily be adapted for the T-Rex 450 or any other 400-450 size heli.
A guide on what to do when you first get your Venom NightRanger 3D helicopter. Some very useful tips, specially for the first timer (Although after flying both the Nightranger 3D and Mini-Titan E325, I WOULD NOT recommend the Nightranger 3D as a first helicopter - This is my opinion!)
A short guide on some initial settings to help you with your Venom NightRanger 3D helicopter
A short guide on the history, types and setup of gyros on helicopters. I can't remember where I found this article, but will gladly give credit to the original auther if anyone can let me know.
