Hi,

Just getting back into R/C after a long, long time. (I built a
"Gentle Lady" glider about 20 years ago).

Well, I have two basic questions regarding a glider that I am
currently assembling.

1. I have a 5 channel receiver and cannot figure out where the battery
connects to! There are 5 sets of 3-pin connectors labeled "1" through
"5", and then a 2 pin socket for the crystal. My servo's have the 3
pin connectors, so they look like they plug right in.

Could someone please tell me where the battery connects to?

2. This glider uses these tiny servos that attach on the wings right
ahead of the ailerons, on the outside of the wing. The instructions
suggest to double-sided-sticky-tape them to the wing. Is this really
a good way to attach the servo's? I'm not sure if I should introduce
extra weight by, instead, using a small mounting plate and screws. I
was wondering if using silicone rubber might be a good option as it
would be possible to remove. Note that the wing is balsa covered with
heat-shrink.

Regards,

MB

The battery can be plugged into any of the servo sockets, 1 thru 5. Make
sure the positive and negative match the positive and negative of the
servos.
You can use double sided tape or silicone, whichever works for you. They
make a double sided with foam in the middle servo tape just for mounting
servos. You can also use double sided carpet tape. If you clean both
surfaces real well, that stuff is VERY difficult to remove and shouldnt
come loose when you dont want it to.

If you run out of slots, plug a "Y" cable into any servo slot, and
plug the servo and the battery into the "Y" connector.

Same thing as having an additional slot in the Rx.

Spot on, Fred...

But be sure the "Y" cable is heavy enough to carry the load of all the
electronics, at least on the battery side. Most "Y" connectors used for
tying two servos together are really too light for the job..

A few years back, you had to roll yer own but now Futaba makes one (Tower #
FUTM4135; Futaba # AEC16 Dual Heavy Duty Extension) from 20 ga. wire. Plug
the battery in one side and the servo in t'other and you're good to go.....

Cheers,

Bill

I have wrapped servos in carton sealing tape(wide scotch tape) and glued
them in with shoe goo.
These were very small servos in a Super Flea.

The battery can be plugged into any available channel. Usually, if
you look at channel 5, it will say "CH5/BATT".
If you are using all 5 channels (say because you're mixing your
ailerons), then take the least critical channel and plug a Y harness
into the receiver, then the battery and servo have a place to go.

Depends on the model. Usually (but not always) the kit maker is
recommending something that has been proven to work IF done properly.
I personally don't trust servo tape, but you haven't told us enough
about the model to know if the extra weight would be an issue.

I'd probably cut a hole in the wing and try to mount the servo
normally.

Thanks all for the advice!

I was reading some other articles on the newsgroup yesterday and
noticed some mentioning that the speed control for the motor also has
a connection for the battery. I have a speed control for this plane
(which I didn't mention) but haven't looked closely at it yet.

In any case, now I understand how power gets to the at receiver!

I started to build the kit last night and, contrary to what I
initially had stated, the aileron servo's actually get mounted inside
the wing, just ahead of the ailerons. I'll give the sticky tape a
shot and see how sturdy it holds. The tape around the servo idea
sounds good too, as I could use an adhesive and be assured that I
could peel it off the servo later.
