[NSRCA-discussion] NSRCA-discussion Digest, Vol 11, Issue 244

[Chris Moon]

Well, before I crashed the plane in August it was great.  Well, great 
when it was not ripping the nose off the plane...twice.  Actually, I 
like the motor.  It does take a different set up from the "typical" 
electric that runs a 21 or 22" prop.  The 20S needs a smaller prop and 
higher rpms to make its best power.  Here are some numbers I got on the 
test stand:


	
	HACKER A60 20S 	
	

	
	
	
	
	
Prop 	AMPS 	RPM 	WATTS 	H.P. 	WATTS / 11 LBS

	
	
	
	
	
18-10e 	71 	7200 	2500 	3.3 	227
17-12e 	68 	7100 	2300 	3.1 	209
19-10e 	80 	6750 	2700 	3.6 	245



Dave Lockhart is the 20S expert.  I can just say if you want a setup 
more like a glow as far as speeds and prop diameter, this is a good 
motor.  One thing is that you need to do is make a back support for the 
rear to keep your plane form losing it's nose.  You need a VERY strong 
and stiff fuse if you are going to try and run one without a back 
support.  Even then you won't know how strong is strong enough until you 
fly it.  By comparison, the Axi F3A motor is stronger and easier to 
mount but heavier. I think what we are finding out is that there is no 
"best" setup.  Depends on weight, plane, but most of all your flying 
style.  I prefer Dave L's flying than the super slow way some people 
have their electrics setup.
