e-Ikarus Piccolo-Eco 8/16 > inverted ???

Hi.

Finally got the headspeed and power to start having some real good fun with this machine but its taken so much to get it to run and fly like it does i have lost loads of faith in the model.

so hees my question. Whats the best way to get an eco inverted without damaging it getting it there.

ive almost gone to do a loop then i back out as i think its gonna cause a boom strike or something like that.

same when ive about braved doing a roll etc.

i always back out just before im about to do it as i seem to have to sort everything out for whatever im doing at that time.

is there anything that should be done before i go for it or is it ok to just do it.

I have done the bell hiller mod to get the pitch so thats there, the brushless is giving me wads of power and headspeed so in theory i should just be able to plan my route in and out and go for it.

but why do i keep thinking that something on the heli is going to give

cheers any help will be greatly appreciated

Just do a side flip to the right. With clockwise spinning rotorheads the heli will flip quickly to the right and back but more slowly forward and to the left (at least someone told me this and it seems to be the case for me). If things go hairy hit max negative and do an arcing flip to upright with the heli facing you nose-in then swing the tail back around. For me this seems to be the least risky entrance and exit strategy on a new machine. Of course a half look to inverted might be easier but i have the feeling you lose more headspeed on the loop climb to inverted than you do on a quick flip and with the back cyclic used to do it that way i agree that if you are gonna have a boom strike from something like this its more likely it happens this way then flipping to the side or forward.

Hi

You kinda confirmed what i was thinking of doing.

that looks like its gonna be the route as soon as the wind drops a little.

cheers for the advice

Hey bro. Me again. Do it 3 mistakes high first. With the mods you have done, you will have no problem doing this. One of the main problems I had was thinking "Oh man, if I crash this thing, it's gonna cost me!!" Once I did it once (after practicing on the simulator for hours!) I was inverted ALOT. Rolled it, looped it, etc. No 3D machine in my hands, but it did what I was capable of at the time. This will be hard, but repeat after me...... "I will fly this thing inverted today or it will go home in a box." Repeat as many times as necessary. Then DO IT!!! Once you get the initial butterflies out of your stomach and roll it, you will have a blast. I have confidence in you. As for the boomstrikes, use SMOOTH control inputs ie: NO JAMMING THE STICKS!!!!! I never had one with my eco. Only had 1 with my rex (Due to hitting the ground and bouncing up!!! Don't ask ) Take a deep breath , repeat my line, and go for it. You won't be dissapointed. I look forward to your post about your first invert. Bill

Also, to roll it in FF, just get some speed and roll it right, drop the collective to 0 degrees at the invert stage, while still holding full right aileron input. As you complete the roll, add some collective and forward pitch. I know you fly planes. Almost the same entry. Pull the nose up a bit before starting the roll and you will exit without loosing altitude. Practice on your sim first to get the stick movement down. What I used to do was fly from left to right in FFF and pull it up into a hammerhead. When it came down, pull up a little and roll it. The thing had some crazy speed at that point, so it rolled pretty fast. Keep us posted. Bill

Bill... Your a funny guy lol

I totally agree with what your saying I have kinda resigned my self to the we'll find out if it does'nt if I end up with a pile of bits aproach.

I was just a touch unsure whether the rolling or looping aproach was the best to try.

I have total confidence in my inverted skills as I often just sit on Reflex XTR doing inverted piros not a million miles off the ground inverted figure of eights and stuff like that and I can hover it as well inverted on the sim as I can verted... Is verted the opposite of inverted lol.

I dont know what it is its just like I have had to do so much to the heli to get it to the point it is now I have lost faith with the model if you know what I mean.

It's like I've had it in its new setup for about 4 flights and I'm sure the tail needs more power now i just seem to be going along this long road replacing, modding and rebuilding to get the model somewhere near to have to do something after ive got that sorted.

The setup I have now is:

401 gyro.
ali side frames.
not 1 but 2 frame braces.
fully sym (BBT) carbon main blades.
AXI 2814/12 motor with 23T pinion giving about 1850RPM on stock head.
120 degree swash setup.
Hardened shafts throughout.
10 cell GP 3300Mah NI-MH packs.
Boom braces.
Tail mounted rudder servo with carbon pushrod.
Ali swash.

And then theres other mods that ive made myself like the bell hiller mod, tail slider and that and its still not right lol.

you know I have a £1000 (well ok £900) setup and still it needs more money throwing at it. its hardly a way for Ikarus to give us much confidence lol.

Or am i just too much of a perfectionist and worrying about nothing at all?

Hopefully you've got thrust bearings installed in the stock head at that rpm! If not you're begging to throw a blade...

Bill's right, don't be afraid to ball it up - it's only money

I had a 30-3 motor with 11.1 lipo and 24 tooth pinion. Did it have a fast headspeed? Not sure because I never tach'ed it. Would it do what I have stated it would do? Sure would. Never had a problem. Is it possible something COULD be waiting to happen? Maybe. I'll never know because it was destroyed by my dumb hands! Just go for it man!!!! I want to read tomorrow that you rolled her inverted.

1600 rpm is the max recommended without thrust bearings - that's with the stock woodies, which are pretty light too.

Unfortunatly its a bit windy to fly at the moment as sonn as the weather is good enough again itll be flipped over.

wouldnt mind but it looks as though its gonna be like this for a few days.

i used to run 1850 with MS CF blades on a stock head and an ali head, ran like that for over a year with no problems. MAybe if it was nearer 2000 then I would of considered the Thrust bearings.

its the tail blades im tempted to be more cautious of they just dont seem to have very much to them. i actually thought about putting a washer onto them just to add a little more support when i originally built it. is there anyway of making the tail blades a lot more secure?

For the tail try the thrust washer /washer combination from Boca Bearings, its a common mod, doesnt cost the earth and works a treat,
site is - http://www.bocabearings.com and the order number is F2-6.

You will need a couple of 12mm stainless cap head bolts to take the extra length of the thrust bearing, takes all the play out and makes the tail a lot more stable

PS - SAB 80 mm tail blades are also a good upgrade, much better than stock (quickuk)

Don't worry about loopingor rolling the heli with your set up. I keep doing it with a stock model, still all plastic!!!!!!!!!

Motor is 2814/12 the same and 22 tooth pinion and it will loop and roll no problem. On ten gp3300 cells it's easy, it will loop and roll on 8 cells without any problem either. The only boom strike I've ever had with my ECOs was also when hitting the ground from a great height so don't worry about that. I don't have boom or frame braces on my stock model either and it hasn't fallen apart yet.

Go for it!!!!!!!!!!!!!!!!

On the Tail I used t run MS GF tail blades with no issues.

Stock grips with two bearings instead of one and hardened bolts (slightly longer than stock to allow for second bearing.

Scoot.

would that be the 80mm glass blades you were running. Ive been looking at getting a set of them with the 35T tail transmission gear.

also i was pointed to some SAB tail blades which i do quite fancy getting but arnt those ones 3mm bolt hole from quick uk?

cheers for all your help guys

yep thats the ones, I tried using a the different tail gear as well but didnt notice any considerable difference so went back to the stock gear.

Not sure about the SAB blades never used them or seen them.

cheers for letting me know.

just ordered some blades just need to work out now how to give myself a bit of confidence with the blade holders lol.

putting the 2 bearings on did you just cover the other bearings with with the second set and were they just stock bearings.

theres no rush at the mo as its windy as hell right now here.... Pesky weather.
