So you're flying with no weights in the paddles?

I'm currently flying with 10% expo on aileron and 15% on elevator (all weights in the paddles) just to make center more soft or I screw up my nice wide round curves... well I manage to screw them anyway... just a little touch to the aileron and the bird goes on knife edge. Thats why I find myself supprised to hear you don't use any weights. If my is that agressive with weights how will it be without them? Uncontrollable?

Cheers

I flew with no weights in the paddles and then switched to the greenies which are even a bit more agressive.

If you have flown the model I posted earlier, then the reaction of the heli is similar. Or if you can fly the Dominion 90 in G3 then you should have no problems whatsoever without weights.

If you are overshooting on your rolls through turns then it's just a matter of getting used to a more gentle touch on the sticks or add more expo.

I spent soo much time in G3 doing figure 8's every which way that it became very boring. I would also always do them close to the ground so that it gave me less room for error and it was easier to see what I was doing (my reset button has a lot of wear). Now they are quite easy to do and I don't have to really think about doing them anymore. They just happen.

Hi All!

More time on the sim is what I need. L.O.L. I crashed EVO last week, I crashed my XRB many times but yesterday and it drop like a rock 8 feet high. This time the landing skids broked into many pieces. Good thing I received a spare skid the other day. Today, just finished the jigsaw puzzle with epoxy and tooth picks. Just missing two small tabs in the back for the tail truss. I need more epoxy.

I think I will spend more time on the sim before flying my EVO once I get it. But this time I think I'll just hover it for awhile.

Man you guys are killing me with the talk about removing the weights and trying different paddles. It makes me .

At least we are learning, right? BUt you guys are getting to test it.

Hi BTDT

Well, after spending 2 hours on the sim today I'm not so sure I'm going flying tomorrow. I think I crashed more times today than all other days together

figure 8s were a joke, stall turns ended looking more like corkscrews, loops resembled inverted high speed crashing and rolls... well, lets say they would look cooler if I did them head down strait to the ground.

I even checked twice my transmitter settings to make sure I was on the correct model... couldn't believe all the mess I did today.

On the good side, my duzi parts arrived today... Man... an entire X3D without glue! finally

Cheers
Tony

Watch out for the next day. That's what happen to me. The night before I was crashing left and right o n the sim. I said to myself, it's only the sim I'm having problems with. Watch yourself and take it slow on the first tank and not whip it around after take off. You all know what happen.

Glad you got all your duzi parts. I'm still waiting for my package.It's schedule for the end of next week.

The Force was with me today
Hi folks.

You won't believe what happend to me today. I was saved not once but twice today by the heli gods.

Here is the story:

I went to the field today to fly a little and to try to setup my ailerons for a future roll.

1st flight everything ok, bunch of FFF figure 8s, piro takeoffs, walking piros etc.

2nd flight - did a couple of loops, everything ok. I then proceeded to my third loop. As the sun was at the same position as the wind I had no choice as to perform loop with the wind. I increased to full throttle, pulled a little back cyclic and there I made the mistake... I inadvertely gave rudder too!

When I realise I'm doing a lateral loop I somehow manage to stop at the top of the loop INVERTED!! I imediately give a little more negative and now its sitting up there inverted!! My friends scream "WOW HE IS TRYING INVERTED!" while I'm thinking "OH GOD what the F**k am I doing?!?" Well, I started to think "how am I gonna go back to normal?" Finally it hit me. Full negative, little back cyclic and hop! I did my first back flip or should I say back jump?

Uff. I landed and had to smoke two ciggs and sit down for a while, my friends came to me saying: Wow man, 4 seconds of inverted for the first time is great and I thought... it took me 4 seconds to recover from that?! Jeez!

On my fourth flight I decided to remove the led weights from my paddles and try to fly like that. Somehow it started to feel bad... really bad and I thought "Man, I don't understand how those guys fly without any weights in the paddles, the heli is extremely sensitve. You just need to look at the cyclic stick and the heli makes a sharp turn".

After that thought, I landed and decided to increase a little expo. I went to the menu and to my suprise I already had 30% expo on elevator and 20% on aileron. I asked myself again how the hell do you ppl fly with no expo and no weights in the paddles? Anyway, I gave a little more expo on aileron (25%) and things started to get better but I had a bad feeling, so bad I landed with the tank half full and packed up my stuff.

When I got home I decided to check my aileron and elevator pitch... then it stroke me... I had 8 degree on elevator and 7.5 on aileron. Way too much. I reduced atvs to 75% and 80% respectively (6 degree ail and elev) and reduced expo to 15% on ail and elev. I hope that will make the bird softer.

I was almost finished when I noticed a shadow under the canopy. What the heck is that?! I removed the canopy and there it was... one of the pushpull links of the aileron servo was hanging down. The screw that holds the ball at the servo arm had broken off. The remaining screw and nut was still loctite to the servo arm but the screw head had broken off. The entire ailerons were depending on one link to my 9202... I guess the servo wasn't up for the job doing steep hard turns and was starting to loose its holding position during those maneuvers. Probably thats why I felt the bird wierd and my battery consumption was way higher than usual.

Man was I lucky today... UFFF

How are you ppl doing?

Cranium: how much expo/degrees cyclic do you have? Is your bird in stability or agility mode?

Cheers
Tony

Congrads on your 4 sec inverted hover. It doesn't matter how you got there. You did it mate!!!!!!!!!!

Nice catch on your heli. If it don't feel right land it.

Glad to see things are going good for you. The Force Is with you.

Thx BTDT. Actually I was terrified and I'm going to stiff up my rudder stick so it doesn't happen again. One thing is hovering inverted on the sim and another is seeing that in real life. I felt totally hopeless thinking "It's going down, It's going down".

Today is raining alot. I spent the afternoon at home installing Duzi parts on the X3D. It's comming out great. I hope that sucker will fly better now and won't twitch that much. I'll post some pics when its finished (during the week I hope).

Btw, I took a peak at your gallery. Is that the Dead Evo? It doesn't seem that beaten up to me. When is your new kit going to arrive? Did you order the SWM or HPM version?

During next week I'm going to take the Freya for a ride. The engine needs to be run in.

Hey Tony,

I suspect that you got the cyclic stick into one of the "corners" and broke the link by getting the swash jammed against the mast. 8 degrees on either of the cyclics is pretty close to the point where the swash hits the mast, so if you had those settings I wouldn't be surprised.

For "normal" aerobatic flying (low ATVs) I have 6 degrees on cyclics and -30% expo (it's a futaba radio). For hotrodding, I have about 7 degrees and -20% expo. I'm flying with just the brass weights in the paddles. Roll/flip rate in low rate mode is about one full roll per second. In high rate mode it's double that.

Even if you reduce the ATVs on the cyclics to 6 degrees, you may still be able to bind the swash to the mast if you push the cyclic stick into the corner. I made a cyclic limiter (circular travel limiter) as an alternative to a cyclic ring to prevent this. You can see the details in the following link. Circular Travel Limiter

I will say that the stock M2 bolts that Hirobo supplies for the link balls are VERY soft. I sheared several of them just tightening them down during the build. It might be a good idea to look into some replacement bolts. Being in Europe, you should have an easier time finding M2 bolts in your local hardware store.

Hi All!

Yes that's the dead EVO in my gallery. The cost to replace all the damage parts are very close to a new one. So for a few dollars more I got a new one. Maybe one day, it'll come back to life, so I'll have two EVO's. Delivery is scheduled for the end of the week. I order the HPM one. I figure to keep them both the same incase I need a part. Not a good way to think. I was told it does not make that much of a difference for my flying or now hovering.

It was pouring rain two nights ago and last night it snowed a bit. Weather is getting colder fast. How's the Esky?

Funny thing, most of the time on the SIM, I can save my EVO. But in real life the heli just drops like a rock. I think it's me, ALL ME!!!

Hi Lief.

Thank you very much for your input. I have limited now my settings to 6 degree max and yes it binds a tiny bit in the corners. I'm going to make myself a cyclic limiter

I don't believe I went into extremes on that flight. I never give max inputs on cyclics not even during a loop. I even was suprised of the little amount of back elevator I needed to back flip into upright position. Since I use anodized hardened aluminium servo arms it is possible that the screw cracked on install and just broke off from some maneuvers I was doing (like full climbout and a strait stop with negative collective). I was pushing it a little I admit.

Thx again

Tony

Tony for exponential on Futaba you have to go negative numbers.. -25% would be a good start for cyclics.Naomi

Yes I know Naomi. What wondered me is that it was touchy with -30%... no wonder with 8 Degree cyclic

Cranium: how much expo/degrees cyclic do you have? Is your bird in stability or agility mode?
Sorry for the delay in response...was out of town for the weekend to help my sister move.

I believe I'm running about 6 1/2 degrees of cyclic. I'll have to double check when I do my rebuild this week to be sure. When I set it up I did verify that I have no binding in the corners and at max pitch on both sides. I set up the bird for agility mode when I built it. I'm also running no expo.

The rebuild I'm doing this week will include some Infinavation dampeners and the metal washout set. I'm hoping this will remove all remaining play in the head and reduce the chance of another boom strike.

Hi All!

What happen to all?

I'm still waiting for my EVO delivery, it's close by. UPS show tomorrow. But it sometimes come a day early. I just tracked it and it's in the next state.. Hope they didn't update the barscan and will be here today.

Do you guys have the XTR sim? I know you've post some G3 files.
The problem I'm having is that the tail vain in flight. Maybe it's me not knowing how to fly. I go left in FF and turn right. The tail swings around 360 at times or if I get it 90 degree, it wether vains back to the same left FF heading? I have to admit that I rarely used the sim. Now I want to get more sim time and to save me money L.O.L. I've played with the radio settings and also the settings on the computer. I'm using HH settings. Which one is the correct one to adjust?

The problem I'm having is that the tail vain in flight.
What you're describing is either a bad radio setting, some rudder trim offset or you're bogging the head down so much that you lose tail control.

With heading hold, you NEED to steer the tail to keep it pointed in the right direction. When performing a turn, you need to input some rudder. For normal Mode 2 flying (upright), you'll push the rudder stick in the direction you want the nose to turn. If the nose goes the opposite way, you've got something reversed in your radio/simulator setup.

When doing hard stick-banging maneuvers, it is possible to have the headspeed drop to the point where the tail becomes ineffective. When this happens, you'll often get a wild spin or two before you can recapture control of the tail. Get used to this... it happens on the real thing too! To avoid this, learn to manage the collective so you don't stall the head. I've seen guys on G2 who set the engine torque specifications at 200% for 3D practice. This teaches very bad habits because it allows wild collective movements that would cause a crash on a real model.

It's worth it to get the simulator settings sorted out so you can learn properly. You never outgrow the simulator. There's always some new maneuver that is best to learn the inexpensive way. Personally, I'm working on backwards/inverted flying in preparation for the spring flying season.
