first flight ina few weeks....ends in crash...

[xcraftllc]

Maybe we should fly with pontoons on when we're out at the rice patties!

Hahaha... It did land pretty hard I think it would of still dunked a'lil... You are the master of crashing because of helicopter failures. You should become a maintenance test pilot...

I broke my landing skids, due to shity GAUI OWB allready 2 time in 30 flights

I use the above OWb and locktite it back into the gaui gear......so far no problems.

just out of curiosity, are you lubing the OWB before installing it? and are you using the 19T or the 20T OWB? the 19T is known to have problems. Also, what is your gearing?

[DerClown]

Im using 19T OWB.
Well Im not lubing it,but the shaft allready has some lube on it. So i gues I have to remove it,when I install another OWB.
But the thing is that the gear has cracked and this is nothing to do with the lubing.
And second thing, I noticed that the new OWB gear is slightly wider than the old one. Maby this will fix the failing OWB problem

[razeyoshi]

I have about $250 in damage due to my OWB failing. Had to set it down in a rice paddy. All electronic damage, no physical damage. A squeeling sound that occurs off and on means the bearing is starting to slip. I figured it was a bearing going bad, the thought of it being a OWB never crossed my mind until it was too late...

**If you listen carefully you can here the squeel in some of the video's I've posted... Well, you can here it better in the original copy. But on this video it does it for a sec right at 16 seconds into the video...

What motor are you using and whats the Head Speed ?
I think mine doesnt jump from the ground,like yours does

In that video, I was running 550cm blades (grab more air than stock), a Z20 motor (980kv), and 15t pinion (+1t over stock, I believe). The rest of the gears are stock... I don't know exact head speed, use the Gaui Head Speed calculator for an estimate...

**You probably already know but when you pull pitch off the ground it moves quicker than doing it after it looses ground effect, be safe if you try it...

yep.. the older 19T OWB was weak and would crack causing failure. switching to a 20T OWB will fix that issue as well as give you an extra 100RPM of head speed. just make sure you wipe the shaft off to remove a lot of that lube, then install the OWB dry.. lubing can cause failure due to the plastic inside the bearing... besides, this is the one bearing that you really don't want to slip

you're in the 2300-2400 range... what kind of flight times do you get and what size battery?

I currently run the Z20a-980 with 15/20/50/61 gearing.. on 2200mah packs I get 4:30 of flight... but the more I fly, the warmer they are at the end of each flight... going to order a couple of the new 3300 Hyperion VX packs in the next month.. at that time I might switch to the stock 42T gear... and be in the same RPM range as you.

here's a video of mine that shows how mine launches... ignore the rest of the video, it was either zoomed all the way out and the heli looks like a dot.. or zoomed all the way in and all you see if clouds...

"one, two, three... " haha that's some good thrust with the z20 i'm impressed!

[DerClown]

First video has more juice
By the way, why the tail drifted ? It should be rock solid

P.S.
I'll try to do video how mine launches.
As for 20T OWB, well... I dont want to put it now with the plastic grips and wooden blades, since my head speed is over the limit anyways +/- 2200 rpm.
But after I brake 2 spare sets of wooden blades that I have and get the CF ones, I definetly try to run over 2500 rpm and hopefully it will perform the tic-tocs like a trex

[mysticmead]

go for it... run the head speed at 2500 or more... when the gears strips remember that you don't need anything over 2300 RPM.. you think a 90 sized heli runs a head speed that high? nope.. they run in the 1700-1900 range mostly. 50 sized helis run in 1800-2150 range... 30 sized helis in the 1600-2300 range... 500 sized helis up to 2500 is fine... the Hurri is a 30 sized heli... the only reason you think you need 2500 rpm head speed is because the trex 500 runs it... that and you're not focusing on collective management... you're stick banging.. if you want to stick bang get an outrage 550 and crank up the head speed.. or get a 500 sized heli (Gaui 425 running at 2500 head speed is wicked)..

I've seen a guy fly the Hurri on a stock Gaui 850 KV motor at 1700 RPM and tic toc like it was nothing.. piro flips.. no problem.. hurricanes and funnels.. easy... this guy could fly the snot out of it.. because he practiced good collective management

[DerClown]

Could you please explain me, what exactly is that colective management ?
You mean, I should find the exact pitch degrees at exact points ?

[xodarap1]

That tail first landing at 4:06 was wicked.. glad she held together.

Good flyers use just the amount of collective needed to perform the manuver....without bogging the motor, or holding hig pitch longer than is needed.

try an experiment.....hit full max pitch and hold it...the heli will jump up and most likely you'll hear the motor bog or the rpm's drop.

Now, limit your max pitch in the radio....or else just don't use full max pitch and watch the heli....it will still jump up at a good rate but the rpm will not deteriorate as much or at all. That is "collective management"....most of us use way too much collective during flight....it strains the motor, batts, and elec system....and shortens flight time.

[mysticmead]

exactly... and by practicing and only using the amount of pitch needed to perform a maneuver you don't need a head speed that is so high that it adds extra strain to the gear train. you'll end up with more flight time and the motor, batteries and the ESC will all run cooler.

yeah... I was really pissed when I saw that he screwed up the video on that landing... I started about 100 feet up and brought it in like an auto... flared big time at the last second and stuck it in place. it was perfect...and I thought it was all going to be clearly seen in video... at least you got to see the flare and stuck landing part... but zoomed in like that it just didn't look as good as it could have...

[razeyoshi]

Mystic, I get 6 min with 20c 3000mAh zippys without over-discharging. I believe in that video I was running WinForce 35c 3000mAh, about 5 min safe flight time without over-discharging. You do notice a very small power increase with the WinForce but I don't believe they are 35c. More like 25-30c. I could probably get an extra min out of each set of batteries but I'm careful not to over-discharge...

Also half-stick in my setting is 85% with 0 pitch. Should be around 2200 headspeed... If my stunt mode setting was 100% at 0 pitch then it should kick out the 2400 headspeed. (according to the Gaui headspeed calculator)

**Looks like I've started a launch your Gaui trend... hahaha... Mystic, you landed that thing as fast as you took off...........
