That's a long trek up there..Your easy star was obviously stalling and if you would have given a little up elevator she would have stabilised.

We guys fly there early mornings about 8 on weekends..Meet prady he will be able to help you out and teach you like he taught me..

cheers

Hey, you should first give me some credit for dodging that pancard clubs board
Yes that was a long trek, but i am used to it as i have been going on that hill almost every weekend for last 3 years.
The stalling was due to wrong model selected on the tx which had exponential throw on the elevator, which i had set for my SPAD. That was fixed later and i was able to get a good stable flight.
But seriously dude, 8 in the morning on weekends!!  I get up at 8.30 on weekdays

hmm.... cheers for Multiplex for holding out against crashes. From a newbie point of view, I have being scratch building and each attempt has resulted in near total destruction. Now, looking at the video, I am impressed by the damage resistant quality of these planes.

Am into my third scratch foamie (a pusher), so lets hope I get third time lucky. BTW, have got hold of a local hobbyist and I think this time things might turn out better.

PS: SunLikeStar, the guys in Delhi/Noida start around 6:30 am

This is confusing. The plane looks like it is tail, rather than nose, heavy. Notice it's tendency to "porpoise". Though that could just be too much control input. But you say you have expo on the elevator.

Secondly, how come the test glide was ok if the CG was out?

Finally, what did you do to continue flying satisfactorily "tiill the TX battery was drained out"?

Ok guys, so it was not all piloting error and it was not the vertical stab....
...

Then I fixed a coin under the left wing and the plane took off without any input
....
...
The plane was later recovered from the hill and flown till the Tx battery was drained out.

Came back to thread after long! Glad that you finally made the Easy* to the skies. The video was nice! Keep it up!

wow 

Hmmm. So for planes without ailerons, even a slight lateral imbalance is such a big deal ?  There would be no way to handle the situation by pilot skill alone ?

I don't think so. For a newbie, handling a aileron is lot more difficult than just rudder/elevator control. But yes, I would think if one of the wings was heavier, then then it would be an issue.

Anwar has posted that it is without ailerons. And it is very difficult to imagine any ARF to have one wing so much heavier than the other.

My questions still remain unanswered by SunLikeStar. They would be of great help in trying to resolve the real problem.

I am sorry Sushil, i totally missed your post.

It was totally nose heavy, actually it is flying with a little up elevator trim. What you are seeing is just me panicking after the first stall.

The test glides were never ok, in each test, the plane just banked and fell, right first.

Finally, i did nothing to the plane, if you see at the end of the video, you'll see that i am comfortable with the control by then. I just moved further away from the hill 

And i totally understand your concern, i also do not believe that one wing is heavier that other. But still i know that i tried to fly that plane ten times and each time it banked right. Then i fixed a one rupee coin half way under the left wing and now it flies easily every time. i'll try to get the wings weighed, but for that i'll have to carry it to the grocery store.

Absolutely the opposite in my experience !  Having ailerons instead of rudder helps the beginner control any "banking to the sides" of the plane while flying. The rudder is of limited use for the same ! 

So I always ask people to start with ailerons and elevator, and use rudder mostly to line up with the runway for landing (that too when I feel they are ready to handle one more control).

A nose heavy plane will not necessarily dip downwards but will be sluggish on the pitch axis. Whereas the video seems to show high sensitivity on the elevator. As you have yourself said, you have got used to this sensitivity. "Up trim" again does not indicate that it is nose heavy. Have you checked if the dihedral is the same on both wings by viewing it from the front? A one rupee coin doesn't weigh much and , "half way under the left wing" shouldn't have much effect.

I have not checked the dihedral, i'll do that tonight and let you know.

Here is the picture of the dihedral. Flew the plane again this weekend without any problems.

With or without the coin?

With the coin. I wanted to have it filmed but as usual the cameraman failed to cooperate. However i have one video that might interest you. I'll upload it in a few minutes.

Here is the video of the first flight last weekend. I had the coin moved aprox 2 inch inwards(towards the fuse). The result was the plane banked again but was controllable.

Anwar,
If you say that having an aileron to adjust or trim the bank/lift on the wings, then yes I agree, but my experience (with the crashes) is that for a newbie making the plan turn by banking is way too difficult - specially if the model is flying at appreciable speeds. I have tried and it and the result is that the plane turned very sharply which was overcompensated on the other side, so then it banked sharply the other side - net result was a wobbly flight and finally a crash

Pankaj

My point was that having rudder only puts the planes in orientations that cannot be corrected by rudder alone even by experienced pilots... unless you have enough height to TRY to do something, OR you prevent the plane from getting into such orientations in the first place (which is again tough for beginners).

Over use of controls is usually just for the initial couple of minutes, and can be handled with dual rates and/or sim training.

 ...I want to learn how to crash an easystar from you......I did my best ...not even able to force it for a hard landing.......awesome videos. Anyways that was a joke but yeah never seen an easy star so difficult like a bull chasing the ground all the time.... . ...hope you will find a solution soon for it....

Bring it to me i'll do it for you, BTW the thread is an year old.

 ....thats Y I was surprised to this thread started by you... ....things have changed a lot in last one yearI guess....

yes, a new member post in it and it got bumped, believe it or not I still crash every week and yes have been flying for 3~4 years now. I am special
