Title: wanted 11 x 4.7 SF CW and CCw for quad.
Post by: chetanmayekar on August 08, 2013, 07:20:32 PM
anybody have these let me know.

If I use 10x4.5  or 10x 6 What could be the major diffrence in  thurst and motor efficiency?
 Any suggestion

chetan it is like asking, if i drive at 40 or 60 what will be the thrust difference, answer is IT DEPENDS ! depends on what (For driving, for instance the gear you are driving in, slope etc) for motor ? the following

(a) KV of you motor
(b) Batt voltage
(c) Number of cells of you batt (Boils down to previous)
(d) ESC you are using
(e) Amp Draw
(f) Speed at which you are flying
(g) and a dimensionless entity called v/nd

answer to your question, you could use 10x4.7 in place of 11x4.7, no issues, just that you system will function slightly sub optimally

you could also use
ecalc.ch to calculate your performance

thanks guys.
I was confuse as this DT750 motor data shows optimum performance with 11x4.7 props.
 I will surely check tht Thanks everybody..
I hope with with 1 inch lesser my thurst may go down to 900g
well thanks for ecalc suggestion i completely missed that one. i will check ...
