finished and crashed the model 8-), AUW was 13.5 grams. It flew well with limited control (rubber only), had i used elevator it would have been a different story

will post the video link.

Nice mini micro plane, Sahil.........The model flew quite good.....only all of a sudden it went into a spin, what was the reason?? did you find out? the blue baby has enough lift due to the under chambered wing. What were the wind conditions when you flew your model,Is it not possible to fly it indoors, say in the living room??

Plenty of reasons, too big a motor, lack of elevator, rubber only control, poor dihedral. Actually it was a loop which made the model uncontrollable.

there was a bit of cross wind and due to high AUW/DD motor setup i doubt its possible to fly in a room.

The best part i felt about all this is i still got my model trimming skills  ;)

Since my last post i build a full size blue baby 24 inch model out of balsa and Foam but was waiting for 4ch airtronics receiver to finish the model. Original plan was to use HK super micro brick with 250mah battery and 10g RCB BLM but the setup needed MOP. Right now in the process of modding the fuse to accommodate 3.6gram servos, 2S 300mah pack, 6gram ESC, motor & RX.

it is one of the most successful 1st time beginner model on the net and "RED" was to enforce the rudder

Post by: rastsaurabh on January 22, 2015, 09:04:12 PM
I know but put it in a way which is in line with aerodynamics!!!!
 this way you are obstructing air flow..... the plane will still fly, but might show unnecessary uplift.
lie them down and sand them so they are not obstructing air flow.

Post by: sahilkit on January 22, 2015, 11:04:35 PM
will do some patch work to make it more aerodynamic !
