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

To select a motor - first start with Power required - watts

Then Thrust. For your kind of plane even thrust > 80% weight should be adequate

Use a Calculator to estimate thrust with different props. Ensure that the power consumed for that prop should be within the capacity of the motor

Here is a RC Plane Calculator :  https://rcplanes.online/calc_thrust.htm

One prop should be CW other CCW. And motors should rotate in opposite directions. Otherwise the model will pull to one side

Which ESC are you using? How many Amps?

You could try using a pair of these motors, with 30 A ESC's

http://www.rcbazaar.com/product.aspx?productid=4108

It's a common motor, available at many hobby shops

Hi, you can use simulation link below and get an idea of your set up before you go maiden.

30 amp esc sir
Normal one that comes in 450 rs

Sir does the motor for clockwise and ccw different motor comes
For both different model motor comes

Sir can I use multistar elite 2204, 2300 kv
Maximum watt 350

Interchange any 2 wires between ESC and Motor and the motor will reverse direction

Avoid high KV motors. You want more thrust at low Amperage

Why don't you read? There is a whole section in this forum on Electric Power. Plus I have given you a link on a very good post by Mr. K K Iyer

Just remember your basics

V = IR
W = VI
T (Torque) = F*R => Torque X RPM = Thrust
Prop Outer dia => thrust
Prop pitch => speed

A "small"  outside diameter motor will give less torque, so less thrust. If you increase the RPM you will get more thrust, but at higher amperage, often beyond the capacity of the motor. Every motor has a rated maximum Amperage

Sure sir...
Sir but it's a request please can you provide me your number so that I can get a proper help.
Or if you don't want to share your number here in this pannel....can email me your number on my email id:
Thankyou sir

There are no easy fixes here

At the end of the day it is only you who has to figure out which motor/prop/ESC to use, and only you to get the model airborne

Read, study, experiment. You have enough to start

Thankyou sir

Sir should i try this one

And dys 30 amp esc

The specs seem OK, and the price is attractive, but I have no idea about the quality

Yes sir

https://www.electronicscomp.com/dys-1100kv-bldc-motor

Sir is this dys a reliable brand....should i go on with this one....speed controller that I have is also of dys

Sir for 1800 kv motor if I use 10.45 prop with 40 or 60 amp esc will it fly then without the same problem...then can the motor take load of 10.45 prop

Sir as i can see in this link their are 2 motor one is Clockwise and other anticlockwise...
Sir when I am connecting my 1800 kv motor for CCW it's giving the air front side opposite direction instead of throwing back
