I would like to run some big lifting blades.
I have the extended boom , ie 33 inch on my X-Cell gasser.
I am told that 800mm blades would be suited but when I measure 800mm from the blade grip I see that this size blade will interfer with the tailrotor. (not a good thing)
Have I missed something or am i getting fed BS.
Who runs 800mm blades on there X-Cell gasser and can shed some light on the subject for me please.

You might be better off with a set of 710 or 720 non-symmetrical. You will get a lot of lift from the flat bottom and better head speed response with the shorter blades. Unless you are running a heavy fuselage, the 800's might be over-kill.

You will need a much longer tail boom than the 33". Also you will need to change the drive ratios. The stock.6.4:1 will not work well at all with those big blades.
xcellgasman101, has done this mod and he hangs out here and in the Remote Video and Photography forum. I believe he called up MA and talked to them about this same upgrade. They provided him with the longer boom and different gear ratio and other info on beefing up the airframe to take heavy payloads. You might send him a PM and find what he did to get his heavy lifter in the air.

If you are wanting to run 800 or 810 main blades,, you will need the extended boom, I think it is somewhere around 35",,, torque tube, and tail rotor push rod, Also MA redesigned the lower main frames, so I could run the newer clutch stack with a differant pinion gear,, I'm running the 11 tooth with 93 main gear for 8.45:1 ratio.. Also, I have carbon upper main frames, so I needed the stiffners to support it,, All in all it is about 450.00 to change everything out like I did.. If you are running 33" boom, then 720 main blades are as long as you will want to run,,, Hope this helps.. XGM
Also, I'm running metal main blade grips.. drilled out to 5mm bolt hole.
I'm running about 1600 head speed now...

Thanks Fellas.
yer that info does help.
As I don't want to fork out $450.
I think running maybe 720 Semisymetrical blades might be a better option.
I have looked at the 695 SAB's but they are black and I would like an extra few mm.
The TG Drehflugel 700mm SS blades might be a better option for me.
Can anyone recomend a SS blade of the 720 size.
Oh and it is for a camera ship.
Thanks Carl

torque, I have never tried a Auto with it since I upgraded it,, have the camera mount under it all the time,, except when I first get to a job, and make sure everything is in good working order, Next time out, I will, and give you the outcome,, I'm sure it will hang forever.... XGM

The only reason I opited to do it this way, is I have a boat load of Xcell parts. and I wanted to stay with Xcell, I really wanted a Spectra G, that would have solved alot of problems (Gear Ratio's), But I'm very saticfied with the way things are going as of now,, I'm not to sure I like the MAH 810 blades.. alittle to aggressive, maybe more Expo, will help..

Well good luck on your AP ventrue, I'm having a blast.. XGM
