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

Isn't there something in the lit. that limits amps to like 50 or so?  What
does 80 do to it?  Curious minds need to know...

  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.

          Has anyone tried a Hacker A60-20 S in a pattern plane and if so
what were the results.
