Beast sucks in the cold

[millerman]

Well both myself a G-bru battled with the cold and both our beast helis (velo 50 and gaui x5) suffered with head wobble the which neither had last week and were perfect so be warned also learnt that gaui STD tails snap off doing pyro flips in the freezing cold don't the grant lol still nice save mate tt gear and skids from 150 ft fall was impressive :0)

Just a thought before you codemn that there Beasty If the air is damp and its very cold you may have experienced blade icing which kills your lift/headspeed and would cause wobbling.

That or you need a FBL system built and tested in Germany!

good save lads

[GravityKills]

check your receiver pack. Cold can have a dramatic impact on its ability to maintain the required voltage. Proof to that idea is the raptor in my signature, rest in pieces...

Did the heli's have time to acclimatise prior to flying? its damned cold, but nice and bright and still however i did not get enough packs charged to make it worth the trip - its been weeks since I last flew. However I did finish the cloak room plumbing with no leaks (proper copper pipe and solder joints)! So was no a wasted day... still lots left to do though

I flew yesterday after updating the Beast to V2 and had no issues whatsoever, it was about -1 all day, no wind. The heli sat in the car for a few hours before I flew so had time to get cold.

I did not fly the velo for about 45 mins b4 going out and g-bru the same I did not however have the same problem with the velo 90 which has a v-bar installed batts were fine as were receivers I'm going to have a closer look later to check mech's and make sure they are ok it's odd because it was only a few deg warmer last weekend and it was fine ??

Strangely mine did not wobble yesterday and I have also updated to v2 however grants is still v1 grant still flew his and the wobble went away but he snaped a tail doing a piro-flip lol very impressive :0)

agreed what really upsets sensors is temperature change. There is compensation and temperature measurement in the software but it doesnt cope very well with fast changes as the temperature of the sensor can be different to the thing measuring the temperature. So with any gyro be that tail or flybarless your best to take the heli out of the car for a while to let it settle at ambient

hmm, I regualry nip out the back of my house in sub zero temperatures and fly my 500 (flybar) from toasty warm in my house with not time for the temparature to soak through. Never had the CSM720 do anything wierd!

[G-Bru]

Very odd behaviour from both our Beast units indeed dude.

Thing is guys, we had both our heli's sat outside on our setup tables so they could aclimatize to the sub zero temperatures. At first Kelly & I thought it had something to do with the upgrade he did on his Beasty, so I got the X5 with V1 up in the air and had the exact same problem!

Not sure if it has something to do with that thick rugged aluminium base of the BeastX units, if I had put my tongue to it, I probably would not have been able to get it off it was freezing cold!

I disregarded Kel's warnings and decided to fly the X5 anyway on the 2nd pack did my first piro-flips for real after lots of practice on the SIM, on the 3rd flip I was about to pull out when CRAAAAAAACK, WTF!!! Hit TH and got the X5 down right way up, I was buzzing piro-flips and my first auto all in quick succession!

As I walked over thinking boom strike, I was expecting the worst, to my surprise the only damage was broken landing gear, boom, TT, crown TT gears and tail blades. First crash I ever walked away from with a smile on my face.

I reckon 1 of 2 things may have happened:

1. Tail blade snapped off whilst flipping causing loss of control to heli?? or
2. Stripped TT crown gear due to incorrect backlash??

Hmmmmmmm................ which one is it????

Hi Ade

sensitivity should be a thing of the past for most modern sensors but can't say for sure on the microbeast. Maybe dampers extra stiff in the extream cold!?

Cheers

I've put a few (OK 6 'cos I'm soft) flights on my Beastx-ed Gaui 550, no issues at all, flew just like normal (original firmware still - if it ain't broke .......)

[tourerjim]

I was out flying 8am till gone eleven this morning no probs with 3 of my heli's with beastx & no probs with the 500 3G & between them I used up 12 packs turn out lovely morning with nice blue sky's

Ordinarily I would agree, but if they have released V2 then they have fixed problems, improved the control loop etc. After flying mine yesterday there is a definite improvement in rolls and it feels very locked in. I would recommend updating your Beast you'll not regret it.

Thanks Dave - I hadn't heard of any "real life" feedback yet - good to hear
