Hi, are any of you using the 'high lift' type of main blades on your heli's for photo/video work?

I notice when I carry my Sony VX1000 that I don't have as much lift as I do when I'm carying my lighter still camera. My engine has plenty of power.

I was considering trying some of the 'high lift blades' which are available.

Are any of you using them? If so, what differences have you noticed when you switched to the high lift blades?

I may try my semi-symmetrical wood blades which I have in my shop, they may be a step between my symmetrical carbon blades and the high lift blades.

So do you have special blades which you use for photo/video shoots or do you just use your 'everyday' blades?

I have been using 810mm SAB industrial semi - symetrical blades that have a reflexed trailing edge.

When I first installed them on my Benzine based camership I was amazed at the climb rate when compared with the 730mm Vario symetricals that I had been using up till then. Although difficult to quantify, I would guess that I have between a 20% and 30% increase in lifting power/climb rate.

I have read a thread here about semi-symetrical blades inducing rocking (not good for video) but have not noticed this with my head set up.

Cheers,

Paul.

I remember posting this question here when I was getting started carrying a camera - the responses were that the semi's provided more lift, but bobbed around more in the wind, so it wasn't worth it.

I never did try them after that!

I use the TG Drehflugel flat-bottomed 840's from cyberheli. I dremel them down to about 800 and then re-balance. That way I get the nice wide chord blade with tons of lift and easy autos.

Daggit uses them during particular weather conditions (Hot & Humid). He seems to like them. PM him to find out more.

Vicks 800's seem to work quite well. Hard to get ahold of, so we order them in three's and fours.

Like Polarman said, the high lift blades are nice for poor lift conditions like hot, humid... but for really windy conditions they get pretty pitchy. That's with high-lift symmetrical . Semi's would be more pitchy.

In windy conditions like we have so much of around here, I actually switch to regular sport carbons (mine are TG Drehflugel ). The built-in forward velocity of the wind adds a lot of lift on it's own.

The other factor of course is the wieght of the heli and gear. If I added a couple-three more pounds to my payload, I'd probably be reaching for the high lifters more.
