About looking at sanjay sir models , i choose a ft mighty mini plan and build it using sunboard, the total weight is 382gms.
As recommended i have a tattu 3s 850mah 75c battery.
Could anyone suggest a motor and prop combo for this plane.

Who recommends that battery? What is it's weight?

You should be looking to match these specs:

Control Surface Throws: 16° deflection (elevator/rudder) Expo 25%

Wingspan: 20.75 inches (527 mm)

Recommended Motor: 2480 kv 250 size motor

Recommended Prop: 5 x 3 prop minimum

Recommended ESC: 6 amp minimum

Recommended Battery: 300 - 800 mAH 2s minimum

Recommended Servos: (2) 5 gram servos

FT MINI SCOUT
Weight (w/o battery): 4.05 oz (115g)

Center of Gravity: 2 inches (50 mm) from leading edge of wing

Control Surface Throws: 16° deflection (elevator/rudder) Expo 25%

Wingspan: 24 inches (609 mm)

Recommended Motor: 2480 kv 250 size motor

Recommended Prop: 5 x 3 prop minimum

Recommended ESC: 6 amp minimum

Unless you are building another model in the FT Mighty Mini series. Please specify

Sir it is ft mighty mini arrow so according to the design this battery was a snug fit.

Wingspan: 29 inches (736 mm)
Recommended Motor: 2300 kv 2204 size motor
Recommended Prop: 6 x 4.5 prop

1. Your model is very overweight!
2. Motor/Prop/ESC  specs given
3. A 2S battery weighs 30% less than the same 3S battery! Also, a 75C battery is much heavier than a 20C battery, which, for 12 A max load is all you need (800 mAh)

Yes sir it is overweight. I have already ordered a 2204 2300kv motor, with a 5 inch prop. I would consider the battery for later on. Thanks sir . Would update you on it.

Good luck 

Do try to reduce the weight if you can. These FT models are very weight sensitive

Couldn't resist sending you this link

His model weighs 80% more than the original design (both without battery). He will need much more thrust to fly. I don't see how replacing a 3s for 2s battery will help, won't it provide lesser thrust which is more important here than the marginal weight reduction (~25 grams)?  I think he definitely needs a bigger motor if he wants it to fly at all. The mini arrow is a racing wing, I can only imagine what a much heavier, faster version of it will fly like.

Just a hunch. Please feel free to correct me.

I did not specifically advocate the use of a 2S, just pointed out the weight overshot already

No point in increasing thrust without reducing weight; this model at this weight with a larger motor is going to need a real expert to fly

Sir bigger motor in which sense? Are you saying higher kv motor?

Sir could you suggest some of your model build as beginner model. FT plans were appealing so i choose it.

Depends on what electronics and raw materials you have available

Well materials can be arranged sir, and looking at your build posts, i think you can make anything fly sir. So i also want to be like you. For now sunpack(corosheet) and sunboard and depron(6mm) is all i have sir. Electronics and all can be arranged.

There are plenty of Avispad builds on this forum

Have a look

The Newbie Might as well go through the RCIndia Gems on plane building rather, would help him to keep from shooting arrows in the dark. 

You could look at
1. Vortex-rc.com
2. Kinetichobbies.com

Thank you sanjay sir , would look into the avispad builds and if possible build one of them.

sir any idea about ft mighty mini corsair

Ft mini Corsair is one of the good plane for intermediate level flyer's. If you are new so dont go directly on corsair. Even if you are new to this and friendly with controlling high speed and your reflexes are developed to take judgement at high speeds then You can surely go for corsair.

which one do you recommend?

can you share the specs of corsair as sir has done in the beginning of the thread,i need a slow flyer so corsair is not the one that i will choose most probably
