Anyone using 600mm blades on a 550e? Do i need to get the bigger boom or can i do it stock?

Thanks!

you`ll need to stretch to be safe , fit a 600 boom , TT n boom supports , you can use the nitro control rod with a couple of mil trimmed off it , or use the carbon 600e pro tail control rod , you need a quick uk long ball link to make it fit , cheers ady

I went ahead and tried my 600mm blades on my box stock 550e and it worked. I won't say it worked fine because I didn't try any traveling tumbles or tic tocs that might flex blades or boom. But, it sure had better hang time on the one auto I tried before I took them off and put the 550s back on.

I'm very curious about this trial.

With the original 600 electric, people said the packs would puff very quickly because the weight of the machine was too much.

With a 550e running 600 blades you have a much lighter airframe, so is it weight that is the issue, or is it simply the blade size itself?

I started thinking about this after I saw two guys at the field with the Logo 500se. This is a smaller heli stretched to carry 600mm blades. Very nice birds and what really caught my eye was the significantly better hang time for autos. However, they are expensive and being the cheap, lazy guy that I am I thought i would just try asking here about stretching the bird (a 550e) that i've already got. I had a 600esp align (which is where my 600mm blades came from) that i crashed last year. I didn't notice an early puffing issue with the 6s 5000 hong kong batteries that i used on my 600esp. But then I'm not a real battery expert, i just like to fly. Maybe if i was paying 300 dollars for each battery instead of 60 i might be more worried about it?

Depends on the type of flying you do. If you fly 3d there is no reason to stretch a 550. If you are sport flying then go for it. I am running 620 a-sym blades on my 550 stretched to 700. It is so much more stable and graceful now. I have a Scorpion motor on standbye for running lower kv when I decide to fly sym blades over 550.
