I green lock-tite my one way bearing gear, waited a day, and had to try it again today. It is 32 degrees outside, damn cold. It's a bit windy too, 10mph gusts. I had to try it anyway.

This is my first CP heli, moving up from a corona. I was a bit nervous to say the least. The one way bearing held this time. I managed to hover for 6 minutes with only a few minor problems. The wind kept pushing the heli around and once a big gust made the heli drop pretty quick, the tail lightly hit the ground. I stopped the heli but there was no damage, thanks to the snow.

I was real shakey even after hovering for a bit and telling myself to calm down and the worst that could happen is I crash. I think the wind didn't help. I even flipped into idle1 for most of the flight but believe me, my finger never left that throttle hold switch! :shock:

The only problem was a small tear in the plastic covering the wood blades? Where the heck did this come from? It's on top near the tip of the blade? I never hit anything, maybe a bug I didn't see, lol. Any ideas? I'll have to put a piece of tape over it and rebalance the blades.

Overall a successful flight. I couldn't believe how rock steady the heli was even with the wind. It's nothing like the sim. Not even close to as twitchy. Now I'm going to go check my elogger and see how much power I have left. I can't wait til my eagletree display is delivered! :):)

Congrats! Nice to hear the 550 is rock steady. Hope to make my maiden flight in a week or so.

i'll bet the tear in your blade covering is from a very small pebble or peice of sand kicked up from the rotorwash. like you said just tape it and rebalance. i don't know about yours, but my gaui woodies were balanced dead on out of the bag with no tape.

My blades were extremely close out of the bag. I think a piece of tape less than 1/2" was needed. I simply took off this tape and moved the tape to the spot where the slit was. Blades were still balanced!

I just flew again, winds are much lower now! No where near as much nervousness. I hovered fine, loved jumping up and down with the pitch, still haven't done much else! Slowly but surely! No need to rush!

I love the z20-980kv. Last flight after 7 minutes I used 2100mah from my FP 3200's. Voltage low was 20.5, 22.5 after flight. How low can I go with these batteries. I'm sure I can go lower, I've read 3.0v per cell is limit, so 18v. How about mah, is there a number I should stay below?

The motor got to 86, batteries 90, and esc 93. Head speed in idle1 was 1950rpm at hover, is this ok with woodies? Max was 2000 at 0 pitch using 14t pinion.

The thing is rock steady with no wind. I could let go of the controls and it would stay in place for quite a while. No vibes at all, thanks to Finless and his videos setup went perfect!!

My corona was fun but this is a whole new level and I'm completely addicted now. I just have to learn how to fly for real! :YeaBaby::banana:banana

Most people use the 80/20 rul on mah used. meaning you can safely use 2560 mah from your 3200 pack without damage....there will/might be times the voltage drops lower due to loads imposed on the pack when your already at a lower voltage.

I just use my Eagle tree with monitor as a gas gauge...I stop after the 6 -7 minutes and see how much has been taken out...I usually get to make another go around or two.

I set my timer for 7 minutes of fairly aggressive non3d type flying on my 3300 poly's

do the batteries discharge evenly? i should say packs not batteries. this will probably be my next heli. my eyes aren't as good as they used to be, so a bigger heli is a plus. my 30 size is just fine. that is if i could hover. i gotta get my trex finished, and try hovering again. i'm down to final setups. the gyro is confusing me currently, but my rex is for another forum.

i wish my tax return would show. oh man. just relised something. i'll now need another 401. AAAAAAAAAAA well hopefully i'll be able to set it up easily after i do this one.
