practical for pattern (245 KV), but near ideal for running glow props. Between
the V1 and current V2 versions, I’ve probably got about 800 flights. On
10S, the motor can hit 8000 RPM on an 18.1x10 glow prop. At the higher
RPMs (~7000+), the “E” props don’t seem too happy (amp draw
relatively high for the speed and thrust produced). Run an 18.1x12 and an
18x12E and the difference is pretty dramatic.<o:p></o:p></span></font></p>

This was purpose built E by Orland last year with long fixed gear as an
experiment (OMS stands for Orland McKee Special) with a C50XL Hacker running on
4200s. He wasn't nuts about the result and traded it off--was then
converted to the A60. That guy wasn't crazy about it either(but I don't
think he had it set up right). Someone was interested in my last IC
airplane(an OMS) and bought it--I had found this could be had the night
before for not too much more than the other--so I turned around and got it
same day--am now totally E. Had to rework the entire innards to get the
balance right with the 5000s--but I think it will be worth it. I've felt
all along that these older designs would be good for E and am fortunate to have
come up with this one.<br>
<br>
Still learning things like you can put too much power to the larger out-runners
and they can go a little(OK--a lot) nuts (screech) if not set up properly
and there is some experimenting with timing and other stuff that will increase
'milage' without loss of power--of which there is plenty.
Still motors nicely in vertical up at 65-70%.<br>

Not quite on subject, but I've been fooling with an electric OMS (pencil
fuse)with a Hacker A60S20, CCHV85 and Tanic 5000s(had to stack them) and man
is this thing easy on batteries!<br>
