Hiller run up.
Hello again,
I was going past Vanguard Helicopters whilst up at Henstridge the other day and watched them start the Hiller 12 that they have beautifully restored. It sounded very nostalgic but I noticed that the blades also ran up straight away when the engine fired up. Is there a direct drive with the Hiller as this does not seem to happen when they start either the Enstrom or the Robinson 44 that they also have.
The Hiller has fair old size blades on it and was wondering if the engine would benefit from being warmed up before it felt the weight of the rotor system.
Nevertheless it still looked impressive and its nice to see a classic restored to flying condition.
Will it be staying at Henstridge or nearby?
Thanks.
