Hi,

I am currently working on a Heli but for my son i want to get a plane.

So i am considering a very low cost and entry level model , although i tried a x-twin pro for some time but it was difficult to control and was almost eaten by a dog thinking it is a bird.

1. Kindly suggest me a simple model which is low cost and easy to build
2. I have rx, servos, motors(outrunner) and esc from the heli thing lying with me.

How can i reduce my initial investmnt and which is the fastest plane to build.

get a MR moss airframe from Mr Sai of rcforall.in  . It cost me just rs4000 with all the electronics( the electronics are worth rs3000+)  so since you have the electronics  just  get the airframe from him. And about the plane, its absolutely stable for a beginner and easy to learn , i got a hang of it in just minutes with no prior flying experience and one more thing is that its very very cheap to repair even with the most horrid of crashes,(trust me on this)  Grin !

I guess the Mr Moss frame alone would work. 

Scratch building is another option (the cheapest option, just need to invest your time).

Not sure this can be confirmed with just KV and prop size alone. One would need thrust/wattage of the motor too.  Do you have the model number details of the motor ?

One can find motors of various thrusts with the same KV rating and a similar range of props.

This should give you a fair idea of the prop choices and corresponding thrust available (where thrust indicates how big a model it can carry).

Note that 6x3 seems a bit big, so watch out for overloads.  And the 30A ESC might also be borderline, unless you are on a smaller prop.
