What Motor Do I Need?

[Joseph Lever]

Hello,

I want to get into this hobby so I made my own plane and I dont know what motor to use
the plane weighs just about 300g without any electronics inside (I don't have them yet) what motor
could lift my plane I was looking at this... https://hobbyking.com/en_us/brushle...943&indexName=hbk_live_magento_en_us_products Does anyone know if that is sutable I just don't
want to have to buy a 60A esc for a more powerfull motor as I don't have a very big budget.

Flute Test power pack B will give about 12 oz. Thrust for your 10.6 oz plane. Depends on your type of flying. I'm a shakey oldster that builds motor glider type planes. I try to have thrust equal to weight. My latest planes.

I would go with a slightly larger motor with a lower Kv, something in the 1200-1600 range.

For what that sounds like, you shouldnt need anything near the 60A esc range. I would say get something like this: https://www.banggood.com/Racerstar-...-p-1083190.html?rmmds=search&cur_warehouse=CN
That motor has a theroetical total thrust of 885g, which should be lots for a plane that size. also that is assuming you are using a 1047 prop. You might not need a prop that size, but there is another thread somewhere about choosing the right prop. Also, that motor should work with a 25A esc just fine.

^^^^this.
Something like this is with 30 to 40a EsC and 8x6 prop is more versatile for planes. And make sure to buy motors come with X mount and prop adaptor.

2000 kv and above is more suitable for quad or park jet.

Keep in mind the 300g weight is empty, by the time you add motor, battery, servos & Rx, the AUW (all up weight) will more than double. It would be good to add up the weight of all the components to get a better handle on the AUW. Then look for a motor that will give a 1:1 thrust to weight ratio.

Thats probably the safest way to do it
