Hi everyone
Please guide me i am a beginner

I have completed the body parts of the plane and heading towards wiring part

From today morning I am facing an issue the motor are stopping after a minute even if they are in full throttle
And then motor is making some sound and not starting again...after few minutes when again plugging the battery then again it's starting for 30 seconds or a minute then slowly slowly stopping
Earlier both motors were starting at same time but now one is starting after another that too after half throttle the other one is starting .
Battery is draining very fast in 1 minute from 12.6 volt to 11.5 volts
Esc is also heating too much

Motor I have used 1800 kv motor A2212 8T
I have used 2 motors same kv
Propeller is 10.45
Battery is 11.1 volt 3300 mah battery
And FSCT6b transmitter.

Please someone guide me  after investing 16000 RS I don't want it should get wasted
Please help me

Battery discharge rate is 25 C
Please someone guide me what to do

Use a smaller prop. The 10*4.5 is OK for the 1000 KV version of this motor. You are using the `1800 KV version. Prop down to 9" or lower

Also calibrate your ESC

Sir I used 8.45 but it's not able to lift the plane

Sir can 1000 kv lift 1600 grams

Need a bigger motor. What's the weight of you model (AUW, including everything, battery too)

No

1600 grams is a big model. You will have to use something like a 3542-1100 KV with 10*7 or 11*5.5 and 60 A ESC

About 3.5 pounds, High Wing Monoplane Trainer, You need about 100 watt/lb

So more than 350 Watts

Your current motor is max 160 Watts

Sir the weight is approximately 1600 grams

Sir should I go on with this will it be successful Sir only one motor of 1100 kv or 2 sir

Sir with that should I change the battery also battery is 11.1 volt 3300 mAh battery
And sir please can you suggest me some other motor 3542 is not available online also

Sir please provide me your number
I need someone's proper guidance
Please give me your number so that I can contact your regarding these problems.
I am not able to properly brief you about the problems I am facing while building and airplane.

@raj.dev,

First the bad news
1. If you are a new pilot, don't try to test fly this yourself
2. If this is your first build, don't try to fly it just yet.

The good news
Beautiful model.

Lots of info needed to provide any useful advice
1. Is it an ARF? (Which one?)
2. Is it a kit? (Which one?)
3. Did you build it from a plan? (Which one?)
4. Is it your own design?
5. What's the wing span, chord, total area?
8. What's the all up weight?

Then we can estimate the power requirements.
More after we get these details...

Iyer sir is correct, start from basics

I'm sorry, I didn't notice before you had 2 motors! In that case, the response is surprising

You should get some amount of flying

Are your props rotating in the correct direction? Have a look at this build, specifically for the prop rotation and kind of prop

Not lift, but is motor stopping?

Good morning sir
Sir i have given the shape of a sport one...
I have used my ideas in making it Sir their is no kit at all used...everything I purchased separately
Sir wingspan is 40 inches...fuselage is 29 inches
Elevator is 14 inches and stabilizer 9.5 inches...

Sir they are rotating anticlockwise both are rotating in one direction and throwing the air back
Sir but because of load or don't know what is the problem after a minute the motor is getting slow even the throttle is full and stopping then...and esc are getting too much heated

Sir total weight is 1600 grams

Sir please can you provide me with your number so that I can brief you in a better way Sir.

Depends on Power (torque), prop, and actual RPM. A 2212-1000 KV on 11 V will not swing a 10*4.5 at 11000 RPM for sure! A 3536-1000 KV may be able to

Then you are overloading the motors!

Sir please can you provide me your number
