Hi Jim,
Sounds like a neat project. I have recently converted an Artemis to 10 cell
and it is a lot of fun.
I use an Aveox F10LMR in it with 10 GP2200s. That's all that will fit!
You should consider trying out the various combinations in MotoCalc. It's a
great program that lets you test drive your combinations before you buy.
I think you will find that the Hacker motors are lighter for the same output
as the Aveox. Due to their better magnet design they can spin faster, and
using the higher ratio gearboxes, spin a larger prop than the Aveox. Larger
prop disc results in moving more air = more thrust.
You will want to keep the setup as light as possible for best sailplane
performance. The added weight will also make it more challenging to spot
land the ship. It won't be the same as landing the TD ships. A landing
that would be normal for a TD ship DID result in cracked fuse on the Artemis
due to the added mass.
All that said, I too had an F10 and an F12 hanging on the wall when I went
to convert the Artemis. I found the F10 to be the better option for me.
Commercial plug warning --
If you are in the market for a new speed control I'd like to suggest a
Castle P-80 for this project. It is a sensorless design, as are all
controllers these days. They work, and they have great support both for
setup and for troubleshooting should you have any difficulties. I think
they are priced comparably to the Jetis, but I'd better find out for sure...
There are a number of reasons that the P80 is a good choice, but in sum,
it's very flexible and options may be selected in the programming that will
help you have more fun and less trouble from your ship.
Yes, I do have a relationship with Castle. I also have some LMR
knowledge...
Good luck, any questions, please don't hesitate to contact me.

Subject: [RCSE] LMR motor for Pike Superior
I am setting up a Pike Superior for F5J next season and am looking for
some suggestions as to what drivetrain to put in it. I have in my
collection a couple of Aveox motors that I have never used: An F12LMR
(10-16 cells) and F7LMR (7-10 cells).
So far, my experience with unlimited F5J planes is with my molded E-
Graphite, which uses a Hacker B50S LMR (7-10 cell). I've been running it
on 10 cell GP2200 packs and it gives the Graphite a vertical climb. I'd
like the same sort of climb with this new Pike.
Few questions for you F5J experts out there:
1) I want to run this plane on 10 cells so as to keep the weight down.
Am I better off running the F12LMR or the F7LMR with 10 cells? What are
the pros and cons?
2) Will I be better off simply putting a tried and true Hacker B50SLMR in
this plane?
3) In addition to the three large wires, the Aveox motors have a five-
wire connector that apparently connects only to the Aveox controllers.
But all other controllers I've seen have only the three large wires.
What are the 5 small wires for? And can an Aveox motor that has them be
controlled by a Jeti or other brushless controller?
Thanks for any suggestions and advice!
