I shouldn't laugh .........that WAS an animal lol

There must be something in the air today... or not in the air in the case of both our helis. Commiseration mate, at least mine was only a 450 I binned... I noticed you had to put quite some effort into getting yours out of the ground though!!!

Whoa ady, that was a bitch. Just the usual you say, whoops, don't want your repair bill my son. Be flying again soon though ?

Been thinking about going 550s on my 550dfc for a while but think you just confirmed that idea. I will be sticking to 520s. That was well quick though that's how a 550 should be. Awesome wot esc did you have on there buddy

Did you say it has developed a wag and strange noises prior to this?

[ady]

i was using a hobbywing 70hv , been flying great with 520 mains and DFC , but thought i`d get a bit more use out of the 12s n scorpion 630 by going 550 mains , was blooming quick tho , zero bog , 14 degrees on col and 12 on cyclic

[ady]

yep , this little-un is normally super smooth , no vibes , no wag , just loveliness , but you can here n see in the video , she just sounded wrong n broke , maybe she was worn up from all the previous thrashings

[jago]

Awesome that defo confirms 12s for me wot gens ace packs were you using were they 2600 mah. Oh yer sorry for your loss.

[ChrisB]

Maybe something was coming loose,boom support maybe causing the wag and eventual failure.

Looks really powerful for sure

[aparkin]

it was so quick i had to watch it twice ouch m8 hope your back up there cutting the air again soon ...

..

on a side note if you was a little less aggressive and less wind you may of been OK guess we will never find out ....will we ??

[ady]

Kind words chaps , thank you . Was using two gens ace 2600 , they combined were only a tiny bit over the weight of the 6s 40c 5000 turnigy I was using before , the combo of 12s plus scorpion will be used again , but I'll use the standard head I recon , although the dfc felt fine , it would be fine for less aggressive stuff I recon

[jago]

I might be wrong but in the video it sounded like main blade strike with tail blades. Kde direct did the same as you 550 mains on dfc with 90 tails on 12s and i messaged them to see if they have ever had a problem . They did message back saying no prob but they thought it was close so they were going to mod a 600 boom and push rod torque tube etc. They said they wanted 25mm more than standard 550 boom and tighten main blades in the grips. Kde direct video is on YouTube
