I've been building a series of prototypes over the past five years & we now hire the current dolly out. Mainly on features, dramas & music videos.
The vehicle is totally based around use with Steadicam & MK-V, either hard or soft mounted.
Step on & off is a breeze & the smooth motors make it a very safe piece of kit to use.
We rig around the Steadi Op & then the focus-puller.
We have our own Klassen for hard-mounting & rig the scaffolding to create better balance for different surfaces; camber on pavement etc.
DP, usually wants to hop on too & that is fine.
You can see a taste of our work on our website: www.flyka.tv
We are also hoping to take pre-bookings for our 23mph model through Kickstarter.
I'd appreciate feedback, but i can assure you that all that have used it, have really enjoyed it & created some lovely shots from it...we just need it to go faster, which we are in the process of doing.
