Bob Sims is the guy who mounted the servo at the tail. He had to hang
his pipe out the front to counterbalance it. Putting it under the horiz
fin puts in the thre tail boom strike zone. Many are mounting the servo
on the boom just behind the frames. Dwight Schilling reports this works
as well as the tail mounted unit.

I have just started building a Gentle Lady sailplane.
I have finished the tail section and I need to decide 
how to connect the control surfaces.  

Should I use a monokote hinge or mylar slots?

Also, I have heard that the wing on the GL can be weak.
The plans include an additional instructions which show how to
increase wing strength by adding more balsa strip to the
first 6 foils on top of the existing bass wood main spar.

Are there any other spots that need strength on the GL.
(I already added small triangular braces to the apex of
the LE of the stab.)

Thanks

Hi all
does anybody out there have any experiances of the BALSA USA 'LAKER' seaplane
they could pass on - building or flying tips. I am tempted to make a built-up
stab instead of 1/4 sheet supplied, and to reduce the span to improve roll
rate (70" -> 58"). also there is a mod sheet on the stab/fin to lift the stab
from the base of the fin up by 1-3/8, but no explanation of why, or how to 
fix them together up there - half-check, or what???

Hinges - use Sig's EZ hinges. All you have to do is cut the slots
and slip them in, then drip a couple of drops of THIN CA into the
hinge area. The hinge material wicks the CA in, it sets in a few
seconds and - voila!

I had a Gentle Lady, built "box stock". It was fine without any
additional reinforcement. Flew it with both high start and with
a Cox Black Widow .049 on a motor pod. Works well both ways. Also
used standard Futaba S-148 servos and a 500ma battery up front.
The plane required about 2 oz. of additional weight in front of the
battery pack to balance. Longest flight was 37 minutes (lots of
good thermal that day).

Good luck with your plane.

pick 'em up again and continue flying. As soon as I see it with my own

RC 56.

Is is a white glue available at all good hobby shops.
It dries clear and has some flex when cured.
But try to only get it where it belongs - clear will still
look bad if you get a finger in it and touch the center of the

Summary: questions
Keywords: faq, rc cars
Organization: Express Access Online Communications, Greenbelt, Maryland USA
Date: Sun, 8 Nov 1992 03:51:03 GMT

I just bought a used rc car and have a number of questions.  The radio is a
Futaba FP-T2NBL, described on its front as a digital proportional unit, and
operating at 29.965 MHz.  The car has a Futaba FP-R102GR 2 channel receiver
that says it has "battery eliminator circuitry".  The speed control is a
Nova 18-III reverse system that allows for continuously variable speeds and
operates in forward and reverse.  I'm not sure about the steering.  I don't
have any manuals or other description, but I know it was bought in Hong Kong
in 1988.

Questions:
(1) Is the radio frequency legal in the US?
(2) How should the antennae be oriented to each other?
(3) How long should the antennae be?
(4) The car uses an 8.4v battery pack (NiCad); how long can I expect it to
operate between charges?
(5) After testing it with the seller and seeing it operate correctly, we found  
out later that it wasn't working in reverse once we got it home.  We hadn't
fully charged the battery before all of this.  Could it be that reverse dropped
out because the battery pack was running low?  Is this usual?  I should have
mentioned above that the car is a belt-driven four wheel drive job.
(5) I've heard that NiCads can develop a memory that prevents full charging,
and that running a pulse of current through the battery at reverse polarity
can cure this problem.  Is there a specific way to do this?
(6) The radio receiver also has large letters "AM" before the frequency; is
this an AM (amplitude modulated) radio system?  What other choices are
available?  What other frequencies can I use with this radio?

As you can guess, I am brand new at rc.  If there are any general pointers
that you can give me, or if you know of a FAQ that would keep me from
remaining clueless, please, clue me in.  I bought this car because I want
to add an attatchment that will require two more channels/axes, so if anyone
can suggest a good solution (such as using foot pedals to replace the pots
and joysticks on the transmitter) that will free up my hands for the additional
axes, please let me know.

Thanks in advance....

No, it is not really a stepper motor -- you cannot step it by applying
various voltages to various contacts.  I believe that if you require
a stepper motor, you may wish to look elsewhere.  Keep in mind that I barely
know what a stepper motor is.

Oh, you can momentarily get maybe 80 amps or so, I guess.  I would guess that
with 'average' ventilation and so forth that you might get up to 20 amps, but
at some point you might have the brushes wear out if you're talking about several
minutes or more at this current.

It indicates an amount of rotation that the brush and brush hood (holder) are
in advance of the magnet positions in the motor can, I think.  If this is not exactly
correct, it does at least reflect the right idea.

I doubt it.  Of course, a motor with 24 deg timing will have neg 24 deg timing while
in reverse, if this matters to you.

It is simplest to go out and buy a $50 ESC.  You can use a pot in-line with
the battery/motor.

 This is a long story.  It means if the FETs are full on, they could pass 100
amps.  You need this number of FETs in the first place to handle the half-throttle
condition where the FET spends a lot of switching time in a high-power dissapation
mode.  So the ESC doesn't need to pass 100 amps at full throttle, but it could.

Rather than dropping power across a pot, the battery energy is pulsed to the motor
at about 2500 Hz, where the width of the pulse is correlated to the throttle.

Well, it is getting to be that time of year when your chances of having good 
flying weather on Saturday is slim.  This summer has been such a good one 
though for flying -at least hear in Utah- that I can't let it end with our 
first snow storm.  (Last Saturday was severe clear and not a hint of wind or 
clouds.)  I have yet to try flying in near freezing weather but I really 
want to this year.  What kind of problems am I going to run into with glow 
engines and all that cold air?  Do I need hotter plugs? Do I wrap the engine 
to restrict airflow?  Should I expect some problems with the radio?  I'm not 
sure what the effective operating temp range of r/c equipment is.  

	Also I would like some hints, advice, suggestions on flying off of 
ice, or snow.  Anyone fly off skis?

I guess I know the simulator you are talking about. I have borrowed it
from a friend of mine together with an Atari 500. It was marvellous! The
graphic is good and fast enough, especially when you don't "fly" away to
far, otherwise the resolution is a problem. I can say I have learned to
fly a heli within a couple of weeks! When I came to our flying ground
with my CONCEPT30 the first time, it took me less than one hour to hover
and a week to start flying along our ground while keeping my position.
I just can strongly recommend this tool which comes with a nearly empty
remote control casing. Only the control sticks and two buttons (for
shooting towards still or moving targets, which is a great way to
practice keeping the heli at a certain postition) are built in. With
that you get the real feeling and not something like "press 'J' for
'left', 'L' for 'right', and so on. As soon as I know the name (it is
just out of my mind) I will post it here.

I just bought a JR radio and it came without a battery connector, so one
quick question....is the middle pole positive or negative?
