As for a guide to the tail brushless conversion due to ptern's software, see

Nice explanation.. I am planning to add a fuselage to xk 110. What shoul be the max weight of the fuselage? Can you please advise
Thanks for a comment. My aim was the RC conversion of some 1/48 Airwolf plastic model (for example, AMT) by using an XK K110 mechanism. I have already built it, and the all-up-weight is about 103g. The motor power of this Walkera brushless is not so large, but the size is small (inner motor). So if you use the original motor and blades of K110, you might get more lift power.
@@k2tokyojponce again thanks for the reply and suggestions Mr. Hino. I am planning to use stock esc and controller board from xk 110 also planning to use blades from xk 123 much more longer and more lift power... anyways I will keep updated on my progress
Hi k2tokyojp. Where did you buy the concave-bottom blades for the XK K110? Could you post the link? Thanks!
Hi, Tuan Do, these blades are not for the XK K110, but hand-made blades by using the blades of some fixed pitch helicopters due to Walkera.
What heli are the concave blades ones from?
Hi, many fixed pitch RC helicopters have such concave bottom blades, but concave bottom blades are weak. So usual (scale ) helicopters have reflex blades (a little concave):

For 3D flights, one needs symmetric blades.
Almost all fixed pitch helicopters have concave bottom blades. On the other hand , variable pitch helicopters have symmetric blades for 3D-flights. Only some large scale helicopters have S-camber profile blades, which are almost concave bottom blades.
