"I was one of the testers for the Airopult prototype. I started flying in the late 70's and I have large 2.5m to small 1m models and all fit the Airopult with no problem.
A quick tip....As I have mentioned, I fly many different size planes so I have marked the extension arms on my Airopult with set up points for each of my planes so that I can set it up even more quickly.
I also repair model airplanes and regularly have to repair planes which have been damaged due to traditional start up methods. I can honestly say that since testing the Airopult, I have witnessed so many benefits of its use. Now I will not start up an aeroplane without it!"
