Try and figure it out. What will happen to the model's balance as the fuel is expended?

Tail heavy when fuel tank is empty but if one balances with fuel then after tank become empty model tends to be nose heavy so...........

Edit: Wait

1. Balance model with out fuel and then add fuel becomes nose heavy and when empty balances again.
2. Balance model with fuel and when empty tail heavy.

.....and better nose heavy than tail heavy, especially if your fuel unexpectedly gets over and you have to make a dead-stick landing - then you sure don't want it tail-heavy 

correct don't want it tail heavy especially in windy conditions starts acting bouncy and hard to control.

With due apology to Sahilkit (not aimed at him!)
This is THE BEST ADVICE to newbies who won't make the effort, and expect to be spoon fed.

its okay even if it was aimed at me 

Sanjay sir....  Again a beautiful build... Hats off....

What to say, I have no words.

Thanks Doc; Thanks Nitesh 

Maiden washed out today - heavy rain since 4 am

Wrong place. Post your question in the appropriate section/thread. Better read RC Gems: http://www.rcindia.org/rc-india-forum/the-rc-india-gems/

Missed the thread sanjay sir,
awesome build .

Thank you Manoj 

When I first saw this I thought this was an RTF!!!!! But then I realised who was posting this and I knew it couldn't be :-)

You sir, by far, are the most amazing builder.

Sanjay sir, mods will have to run a separate sweepstakes for you, where all your models will qualify, the mods wont need a judge and we all know who will win. That is one of the finest builds. I love the stars on the empennage. Lucky to have seen this model in its making.

best of luck for the Maiden
