Bee 490 ( wing )


I glued one of the Bee 490 wings together ( just the foam bits )
Really wanted to get some idea on weight ( 34 grams for the foam bits )
And what I was going to do with the wing ?

1s Brushed or 2s Brushed / 1s brushless or 2s brushless

F949 F959 or something else ?

Hmmm , to many choices !

First I need to do more 1s brushless testing ..

Planning things out ( The best laid plans and all that )

34 grams for a base weight ... ?

Motor choice - Do I go for something small and light ? 3 to 4 grams
And then expect thrust in the 40+ gram region ( limited testing so far )
Or go for a heavier motor 10 gram , and maybe get 90+ grams of thrust . ( 1s )

Oh dear , if I go for Uber light , then I will have ? thrust .
But if I go higher , I may have better than 1:1 thrust to weight .

Small motor 4 grams ? Rx 3 grams , ESC 3 grams = 10 grams maybe ?
This would make about 44 grams ..
Then add ? servos and battery and hardware .. Possibly 60 something grams flying weight with 40 something grams of thrust .

The other way , with a 10 gram motor .. It would be only 6 grams more weight for the motor , but a heavier battery needed for CG possibly ..
So maybe 70 something grams with 90+ grams of thrust ..

Interesting .. No?

All up I have 4 wings to put together ..
One wing will be FPV and I did hope to put a flight control board on it .. ( Flight control board ??? - no idea where it is - post ? )

Oh well ! things to mull over ...
