Looking from behind the prop, you are right, it should be clockwise.  Looking from behind the plane (for a pusher), it should be counter clockwise.

I am little bit confused. Here is a snap of both my build & axn. i have suspended the props such that if the motor rotates clockwise the LE will cut the air first. should i have to flip the prop?

This looks right, how ever it is Smiley

The way I try to remember it is, that glow engines always rotate counter clockwise when viewed from in front of the prop, regardless of pusher or tractor.  So for a pusher, the pitch has to be reversed.  For electrics, the option is there to use a tractor prop, along with reversing the direction of the motor.  Using a tractor prop in pusher configuration is less efficient though.

Learning to Fly



I could never figure out the 'reverse prop'. Anyways, for using normal props as pusher do the following
1) The curved side of the prop (where there are markings) always is pointing in front direction
2) The interchange any two wires in the motor so that it starts spinning in counter clock wise direction

 Grin Grin Grin Grin yipppeeee Grin Grin Grin Grin.  
my plane flied today, it was awesome.
I was very happy & excited to see it flying.

I faced a few issue.
The plane was tilting to the left first (used trim to turn it back) & added, this is the first time i am actually flying an rc plane  Tongue Roll Eyes ).
The plane was little tail heavy, always had the nose pointed slightly upwards. when i push it down a little & leave it, it remained stable. But when i gave throttle again, it pushed the nose up.

Sad part
 Bang Head Bang Head Bang Head I didn't have a camera to capture it(feel very bad, this was my first time flying added this was my own build)  Cry Cry Cry
the plane hit few coconut trees here & there, finally it took a hit on a coconut tree & fell down damaging the battery. that's where i stopped and came back home.

Though it took lot of hits, the plane was intact & the only thing i lost is the spokes on one side of the wing. The last time when i flewed was without the spokes  Giggle that's when it took a hit & damaged the battery.

Congrats on the successful maiden  Clap

This happens mostly when the thrust angle is not correct, you need a little down thrust  Thumbs Up

oh sorry i forgot that it's a pusher; in that case may be you have to much up thrust, making the motor angle more upward will only increase its climbing tendency. Check if your wing and horizontal stab are in the same plane, if the stab is good then decrease the thrust angle by a very small amount.

my horizontal stab plain seems to be little lower then the wing plain. Is that the reason for this?

no problem just make sure both planes are parallel, just reduce the up thrust a little and try tomorrow.

Thanks Cheesy sunlikestar for the advice will try that tomorrow.

Also i have replaced the Aeoxon ESC with 70-80 amps hk ESC.
Cos the Aeoxon ESC was shutting down if i give 60% throttle & use ailerons at the same time. Also it helps in making the CG.

But sreedhar i couldn't find a proper ground to fly again. The ground i went yesterday is totally crowed with people playing cricket today. I went to INCP ground in kariyavottom, The security at the gate told i need permission to fly. We need to find a proper ground to fly  Angry.
