Hi everyone !
I am looking for a Nosemount which would fit our Chopper AS-355/TwinStar and can handle the Varicam with the short Zeiss DigiZoom.
As far as my research goes, it´s very hard to get that mount here in Salzburg/Munich or around. And unfortunately the production company cannot afford to fly it in from far abroad.
So if anyone has an idea.. please let me know !The One-Day-Shoot will happen in about two weeks... All best

Lutz, You didn't specify what type of Nosemount you're looking for. I assume from your mentioning the camera type and the cost factors involved, you're talking about a Tyler Nosemount. In order to install the Tyler Nosemount, the helo must be modified, and Al Guthrie's tabs installed. It's not a difficult proposition, but first the aircraft owner must purchase the STC from Al and then have the work done. In any event, no type of nosemount will fit a an AS-355or AS 350 without some modifications or the shipping in of external brackets for such mounts as the Wescam or Spacecam, as well as the rigs themselves. The most cost effective way to proceed would be to find someone who has a Bell Jet ranger or Long Ranger, since the Tyler Nose Mount is designed to fit these aircraft without any modifications.

Be very cautious using a Varicam on an un-stabilised nose-mount with the Jet/ Long Ranger. The combination of vibration from the twin rotor blades, and the small diameter head drum on Panasonic cameras can cause the heads to lose contact with the tape. Unless you use a VTR inside the cabin, of course ... Cheers, Andrew McClymont

I don't want to get into the number of blades myth again, but the number of blades -- Jet Ranger vs A-Star or Twin Star etc. -- is really unimportant. The only factors that count are the condition and maintenance of the aircraft and the tracking/balancing of the blades. I recently shot with a Varicam (no deck inside) on a Tyler Nose Mount on the world's highest time Jet Ranger flying, N206BH, built in 1968. It was also one of the smoothest flying helicopters I've ever flown in. Other than bugs on the lens, there were no problems.
BTW, tape lift is usually caused by maneuvering of the aircraft in such a way that wind is allowed to enter the tape chamber. If you can't use a deck, the simplest cure is to seal the edges of the cassette loading door with tape.
A couple of other points regarding the Tyler Nose Mount and Jet Rangers :1. You can see the camera and lens through the chin bubble so if anything is going awry -- such as bugs on the lens -- you can see it.
I agree with Brian.....I have rigged tape based cameras in a lot of high vibration environments including of course Jet Rangers. In my opinion...if the mount or entire aircraft is vibrating enough to induce recording errors...the pictures you are capturing are most likely quite marginal anyhow. The Tyler nose mount really needs the most amazingly balanced chopper money can buy. Most of the time you don't get a chance to test fly a bunch of aircraft and be choosy. Also, I have had better luck with small drums rather than larger ones (ie.Varicam v. F900). The light weight and small diameter of a Varicam drum give inertia less to work with. I mounted an F900 on a roller coaster and had dropouts in the high vibration and high G areas. I did not see these problems with a Varicam on the same rig. Ultimately the best solution was a separate dampened recorder and a T950 head with a prime. Less weight less inertia to jiggle the mount. Carlos Acosta
Tyler nose and Jet Ranger with Varicam should not give you any problems. You must stay on wide angle lenses though.You can rig a libra head to a Jet Ranger as a nose mount. It's a pretty attractive option in my opinion and only marginally more expensive than a Tyler nose mount. I don't know who does it in Europe but I can refer you to a guy who likes to travel...

My experience on that has been a little different. People routinely and successfully zoom with the Tyler Nose Mount. In fact, Tyler has offered a zoom control with the Nose Mount for years. (I prefer using a Microforce video zoom control rather than the Tyler control myself.) However, good results at longer lens focal length depend more on the condition and maintenance of the helo, than on focal length alone. Good results also depend on the experience and skill of the pilot -- since the pilot is really the camera operator -- and, of course, results depend greatly on the weather. With everything in your favor, you can zoom in quite a bit; on the other hand, if things are against you, then even 4mm is too long .In any event, with an RCU, you can check your results and adjust the focal length accordingly without having to land.
P.S. If you do use an RCU and a Microforce, bring lots of Velcro to attach the RCU & Microforce to the Tyler controller, and extension cables.
>> You can rig a libra head to a Jet Ranger as a nose mount.You can rig anything to anything on the ground. But for aircraft it's a very different story, and it's not so simple.
Brian Heller :>>Back to the original post:? Isn't MHS (Munich Helicopter Service) right in Munich? Yes, MHS is in Munich. They have Tyler Mount, Wescam , Continental Mount and Nose Mount.
