Looks pretty. Why not decorate it with some coloured tapes etc to give a complete cessna look...
Just a suggestion... Also, post videos of flying.

@docnayeem
Well done sir.
Consider adding some nose weight.
Regards.

Even I thought for this once. Try re balancing the CG.

mod = model as I could understand.

@docnayeem
Appears to be flying in a tail down attitude. Reason could be:
1. Tail heavy, needing forward pressure on elevator stick to prevent zooming
Or
2. Nose heavy, requiring lot of up trim and/or need to hold some back pressure on elevator stick to maintain height. If so, will nose up when speed increases.
Or
3. Needs some downthrust, ie, motor pointing 1-2 degrees downward.

Where is the CG presently? (as percentage of chord from leading edge)

The cg is 25 % of cord ...
