is the belt too tight? or is the motor gear too closely attached to the main gear? not sure if these may cause problems but i Have seen that when these are thight and when i turn the rotor in my hand, its a lil hard.

Vinay, thanks Will look at that today. Should i bother replacing the feathering shaft ? could that be an issue, or perhaps work on blade tracking ?

y dont you check the current consumption using a watt meter?

I do not have a Watt meter. This is my first electric model, so i will need to get one soon now. I tweaked the heli and i think the belt was too tight. I will fly this tom morning to see, but I read through several forums, and i think it should be better now.
Will post here the results, first thing tomorrow.

BTW is your HK450 T back in the air ?

It was built long back but could not goto jakkur. will fly this sunday for sure also awaiting the plastic 450 for that careless flying.

Ok, I loosened the belt yesterday and also rechecked the motor pinon-main gear mesh.
It made a huge difference !! Got back my 10 minute flying. Thank you so much !
I didnt know that a tight tail belt could rob so much of power !

Even I didnt know that was a issue, I just suggested that based on my experience with turning the rotor with hand with a tight belt

Also was your pinion-gear mesh tight as well?

BTW I am getting good at side hoverings. SO now i can hover for the entire battery pack, with the heli pointed straight left or right. I am happy with my progress so far. Just a month back, side hoverings looked so tough !
Also practising little forward flights. Coming from airplanes one thing i realise, is that with helis you can loose orientation much much easily. So very important to keep them at whatever distance is needed for a clear vision.

I have 4 battery packs, and so did 40 minute of flying this morning , and will do the same in the evening.

One more thing, i would like to share, is that mini Titan is a "Terrific" heli. Rock solid, and good quality parts. The price isnt that much too, so I would recommend this heli to everyone. The spares arent that expensive too.

pinon was not that tight. The main culprit was tight belt.

Orientation wise Iam can fly in any direction any minutes, though I get confused 10% of the time. Tail in nose in, sides are no prob on hte sim. Practising inverted hovering tail in now. You are lucky you get practicals every day

On sim, I can do Nose-ins for a long time. But in real I still get nervous.
I think practise will improve.

BTW Is it a good time, i should move to using the the full pitch curve ? Ie the Ide-up one ? Right now my pitch curve is -2 to +10 and hovering at midstick.
Would it be better for me to change and practise with the idle at center stick ?

Ujjwal always used to say sim is not a very very good idea, though he supports sim upto an extent, I recently visited his house and tried playing G4.5 on his 4 year old Laptop. It was crap. I couldnt even hover my favourite heli for 10 seconds believe me. THe Frames Per Second was around 8 to 10, and it was jerking. The graphics was crappy. Not even grass was displayed properly, forget the CPU expensive physics calculation-simulation. The PP Joy connection he had made was working like as though he had set the TX on -ve 80% exponential. No wonder many people hate it.

G4.5 requires a high end system to look good and the physics to work best. You have to select in the options to simulate good physics.

I have a high end gaming system with 4gb ram 22"LCD and a 512MB GeForce 8800GT series graphics card with a very good DYNAM 6Ch simulator. And it really rocks.

Tomorrow I will know the diff b/t sim and real for real, since I have better orientation now, I can confidently hover, if I find Rajesh in time, before I loose patience and start trimming myself.

Oh God, give me some patience.

If someone wants to go with this heli, i would recommend reading through this entire thread. Has a lot of valuable information

My mini Titan's ESC has an option I do not understand. It is Flying mode :
Helicopter with governor
Helicopter without governor.

What is the difference, and advantages of each ?  What should i use ?

I read about it some time back. Its like its tries to keep the head speed constant under varying load and eat batteries, does not allow the heli to boggle. Not sure if governor can be used on 0 50 100 throttle curve.

EDIT: Did some reading and came to know that its used to set a flat throttle curve. SO when flying no matter how you fly or even in 3D, the governer will maintain that same head speed. So no need to have that V throttle curve if using governer. Beacause of this flat curve, rather than the V curve or the beginners 0 50 100, governors tends to eat up more batteries.

Did my first nose in hovering today.
Was only for a few seconds before i got nervous, but at least i started on it !
I do not have anyone around to make a video or take pictures. I am thinking will put my camcorder on a tripod and then fly.
3 flights down and hope to have at least 6 more today.

Guys,
I did a total of 7 flights yesterday in my garden. I am now being able to confidentially hold a hover with tail in , and sideways with both sides. I am also doing some forward flights, as you can see, and next target is to master nose in hovers.
Then i will be attempting to do squares ( or rectangles ) .

Following that, will go to a bigger field and start doing stall turns etc..

Anwar, Vinay, Rajesh and all other heli fliers, please do comment on my video, on what I can do to improve.
Thanks
Gaurav
Oh, here is the video :

It is natural for most people to get into fast forward flight and smooth figure eights before they do nose-in hovers. 

Either way, I would strongly recommend that any significantly new move should be tried at a bigger field, with the heli at a higher altitude than what is you are flying in the video   For banking turns with both aileron and rudder, you definitely need more altitude to recover in case you get disoriented.

Also, it seems you are always turning in the same directions (left turn when the heli is on your left and right turn when the heli is on your right). This is OK for now, but you should make a deliberate effort to do it both ways at the earliest.

Thanks Anwar.
I am keeping the heli low, so i can land in case i get disoriented. But i will go to a bigger field and practise, but after i am confident with nose in hovering.
I have found that going to a bigger field, gets me more relaxed, and hence invited trouble. I go to far, get disoriented and crash. With a smaller space, i feel i am learning to fly in a much more controlled manner. I havent crashed flying at home, and yet crashed thrice on the field !

Regarding turning, When the heli is on my right, I make a left turn and when its on the left, i make a right turn.
THis is to avoid getting the heli to nose in .

When the heli comes nose in , i do get a little nervous but i guess will be better after a few flights.

Whether you realize it or not, the heli is already nose in for about 50% of the time ! It is not in a "nose in hover", but it is "nose in" !

The way you are turning give you the feeling that the heli is "turning away from you", which is comforting to many (the same applies to airplane flying), but it seems to have not much to do with "nose in" itself.

I still do not think that in the above video I got the heli to face me nose-in at any time. It was either with the tail pointed towards me, or one of the sides...Yes i am turning away from me on both left and right, and that is to avoid the nose-in at which i am not very comfortable at this stage.

What I meant is from a "heli coming towards you" (or "closer to you with the head of the heli leading the way") perspective, which is exactly what happens in a nose-in. You right as in it never directly pointed towards you, but the way you apply controls is the same.

So what you are NOT doing is a "nose in hover", but you are already controlling it as if it is in a "nose in".

I get what you are saying. After i practise not getting nervous with the heli facing towards me, i will start doing turns on both sides.
My next agenda is to get the heli to hover with the nose towards me and keep it in one place so i can get comfortable in that orientation.
Of course doing everything but not crashing !

Where did you buy this from? How much did you pay?

I came across this : http://www.littlerotors.com/flyinglessons/index.aspx
Looks like some nice tips for myself, Vinay and other heli learners
