I was not happy with the result, and abandoned it after several test flights. Vufine display is not convenient to look at during the flight. Instead, I mounted AON2 on helmet front. This configuration works pretty good.

No

15 liters fuel bladder. Will be on the lower back, right behind BOC.

I need to make openings for engine mounts. You can see some details here – https://www.facebook.com/photo?fbid=2906758286118203&set=a.678091862318201 https://www.facebook.com/photo?fbid=2697855983675102&set=pcb.2697856870341680 https://www.facebook.com/photo?fbid=3098818256912204&set=pcb.3098833303577366 I will ask advice from our riggers, but cannot ask them to do the job. They don’t have materials and experience to modify wingsuits.

I need to do several significant modifications on ATC wingsuit. Since it is going to be continuous research process, I decided to obtain all necessary materials and skills to do it myself. Thereby several questions: Main surface material (like 210D Ripstop) – what are my options and where to buy ? What thread (size, type) should I use, where to buy ? Needles for sewing machine – type, size ? Are ball-point needles preferable ? Sewing machine – for start I intend to use household Bernina machine. Does it makes sense ? If not, what do you recommend ?

Well, I already ordered C4 suit. And I think jumping from ATC to RACE is too much. I will use C4 for a year or two before considering further upgrade.

Wow, you made it very clear. Thank you for comprehensive explanation. I will go for C4.

I own ATC2, pretty happy with it and intend to keep it for any-style flights. But I’m considering to buy additional, larger wingsuit for single purpose – to stay longer in air. No acrobatics, no base and no flocking with it, just cloud surfing as long as possible. Which one will be better for this purpose – Freak or Colugo ? Or there are other brands which are better matching my purposes ?

Indeed my intention is to stay high above terrain. I booked Eiger WS flights, which is considered skydiving rather than BASE. Obviously there are still several dangerous situations which can develop, such as quick loss of altitude due to bad exit, or flying in wrong direction. Are there other dangers which I should be aware of ?

Thanks, this is exactly what I was looking for.

Can somebody recommend skydiving clubs in Alps area (Switzerland / France / Italy) which offer wingsuit jumps from helicopter and have well established flight lines over terrain at safe altitude ? By “safe altitude” I mean that terrain has slope similar or steeper than WS descent angle so if I will exit at 3000 feet above and will fly in the right direction, I will continue to stay at the same altitude above terrain all the way down until deployment.

Photos of helmet with Vufine HUD installed and connected to smartphone. The display of application running on phone is mirrored to Vufine. A lot of work to properly install it in helmet.

Great, thanks ! I will post update as soon as I will have chance to test it in flight.

Maybe I will end-up with RPi, but meanwhile seems that smartphone applications are working pretty well. Their accuracy is better than mine ability to exploit accuracy advantage :-) But presently all tests I did were by car running up/down the hill, not sure it represents well enough wingsuit flight conditions. I’m awaiting for HUD arrival to test these applications in real flight.
