What is the brushless kv number that has about exactly twice the power
of a brushed 400 motor? I want to upgrade my GWS Slow Stick and
exactly double its power.

I got out of flying airplanes over 9 years ago and I am looking to
sell all of my stuff.. I know I spent thousands over the years I did
fly.
List of airplanes that are ready to fly.. add receiver and battery

Joe Bridi- Vagabond 40. with a Magnum 46 engine, low wing sport plane

Joe Bridi- Krafty 60 with a K&B 65 sportster engine. I took most of
the dihedral out of the wing while building.. It is a great flying
high wing plane. I have floats for it too. The floats need to be
finished and painted.

Joe Bridi- Warlord 25 with a magnum 32 engine. Great little low wing
sport plane. You cant get this kit anymore. I built 3 of them..

Global- trainer 40 with a magnum 40. Only had one flight. This is the
only plane I will sell complete with engine and radio. a Hitec focus 4
radio on channel 39.

Kits-
Joe Bridi- Sunfly 4 60 size Complete kit ready to be built.

Joe Bridi- Utter Chaos 60 size. This plane is 60%% done. Wing, tail
and fuselage is done. Servos installed Hitec 425 servos.

ill take the lazy bee if he dont want it.

There are so many different options, and the specs are often
incomplete. From my research it seems that the kv number
that all of the brushless motors provide is an incomplete
specification. From what I read what really counts is the
Watts of power, and Watts per pound ranges from 50 to 250
depending on the performance desired. Is there any way to
convert the kv number into Watts?

What other things need to be considered? (motor diameter,
the shaft diameter, the shaft length, RPMs, torque, volts,
amps draw)
I don't know what the final weight of my Slow Stick will be,
I am guessing that it will be somewhere near a pound. It may
go as high as two pounds with a heavy motor and battery. I
am shooting for the best performance for the least cost,
thus I am starting with NiMh batteries.

The best guess options chosen so far:

I read yesterday that these batteries can handle a constant
10 amp draw pretty well. Actually I saw a graph that showed
their voltage drop curve posted on this group, I think it
was a 2002 post. I want to make a battery pack for my GWS
slow stick from these. I plan to use the simple conventional
(spring on the negative end) battery holder. Does anyone see
any problems with this idea?

Can I run a 7.2 volt motor from a 9.6 volt battery if I keep
the throttle low?
I am guessing that If I keep the throttle below 65%% there
should be no problems, is this guess correct?

A great saftey idea for the pages of RC Report (8/2007)

THROTTLE LOCK FOR ELECTRICS

The complexity of the programming will depend on your transmitter and your
familiarity with its requirements.
Note that you must have a computer transmitter with a free mix available,
and the ability to assign the mix to the switch you want to use for the
throttle lock.
You must also be familiar with setting up a mix on your radio. During the
programming I recommend using a servo connected to the throttle channel
instead of an ESC, to make it easier and safer to see what's going on. I'm
using an Airtronics Infinity 660 and a Futaba 9CAP, and the only difference
is in the mixing points.
First the mix should be throttle to throttle, and set the Rate to -100%% for
up and down stick.

Anyone here familiar with Royal plans. E-bay has a Mitchell B-25 plan
listed. Thanks, Ted.

Thanks for the feedback and here is the thread for my restoration
project of the J-3 Cub with some pics.
