[RX Dual battery diagram?]

i've recently done this.

plug in the radio receiver, servos, battery and esc as normal, but just physically cut the red wire that goes from Rx to ESC, leaving the other 2 cores (black and white) intact.

thats it really.

[how much dihedral]

i am fitting ailerons and flaps to a previously rudder/elevator model.

question, before i cut the wings in half, how much dihedral can i get away with without affecting aileron performance

span is 78"

section is about a clark y

chord tapers from 9" to 6"

i don't want a flat wing as they look "droopy" and it's a "looks like" a real sailplane

thanks

hi

it's only damaging to the atmosphere if it goes off....and i reckon all the smoke from a house fire would be more damaging

after your fire i had a thought

i keep my pc, server, cctv system and various other computers running in the celler (remote access, bit of a geek in computers)

and i have an automatic Halon fire extinguisher above them. if it detects a fire if dumps the halon into the celler to starve it of oxygen. 

no water etc so no damage

 

 

a word of warning... you MUST isolate the system everytime you go in the celler. if it goes of when you are there YOU WILL SUFFOCATE

 

just an idea.

two Tx  Futaba T6EX  and a Skysport 6.  Both 35

 

i am no longer in a club. the one I used to be in has all but given up on sloping. it used to be it's main stay (competitions, scale, everything) but no longer. it doesn't  even 

have a dedicated slope anymore.

 

i go to the slopes i have known for years and more often than not mix with the hang glider crew..I guess i've been a "loner" for about 10 years now (i'm 64}

cells are 4.2v charged, so i have to go 4.2v or 8.4v

i've stuck an old electric motor and speed controler from "somewhere" in the front of an old sailplane.

it's got a 5 cell nimh battery

this combination will pull the 'plane of the table (i'm old school,,,build em light) and will run for about 7 to 8 mins.

 

i just thought i'd give it a whirl but i had concerns about the battery as this all started as above

 

 

everything charged up ...motor battery (red wire to Rx cut)  Rx battery and Tx battery all ready to go.

now wait for a nice 10 to 15 mph from south to west and i'm out there

i shall also take my faithfull phase 5 sport and my new (old) soarcerer

 

fingers crossed eh?

 

cheers everyone for the help

you was both lucky and unlucky there i guess.

 

all my batteries are either nimh or ni-cads

 

taa

Wow...

It appears that I live in a different world to everyone else.

 

"Sensors are connected to the RX which transmits the data gathered back to the TX to monitor onboard parameters such as altitude,"

"a timer on the TX activated by the throttle stock"

 

I have a rudder, elevator, ailerons and sometimes flaps.

 

somehow I think my age is showing, the world is moving too fast and i want to get of

 

so. thanks to everyone but i'll go with this idea

            "Re using a separate 4.8v Rx/servo battery - cutting the red ESC to Rx wire as you suggest is the normal method".

and when the motor doesn't spin anymore i will know that battery is flat but i can keep flying as long as the wind blows.

"Re using a separate 4.8v Rx/servo battery - cutting the red ESC to Rx wire as you suggest is the normal method".  

 

 

i think i'll go with this one. i understand that, and normally a flight for me lasts several hours once it's up.

so seperate radio battery it is.

hi

thanks to all who replied

in most cases i have no idea what you are talking about.

LVC.timers, telemetry,BEC,ESC..

think i will stick to throwing it of a hill

thanks everyone

 

p.s. built myself a new 'plane over the christmas holidays. a dave hughes soarcerer, with flaperons and i still use 35mhz

sorry guys    i guess i'm still stuck in the old school

[how many batteries]

first off...allways been a sloper (40years)

i have recently cut the nose of one of my slopers (50", thin flat wing section, rudder, elevator flaperons) and stuck an electric moterin it

I have a 7.2v battery to power the motor but when i connect everything up i notice this battery also powers the radio (receiver, servos)

question

 

what happens when this battery falls flat enough to no longer power the motor, wil it also be too flat to power the radio and therefor "crash"

or

if i have two batteries, 1 for motor and the normal one for the radio, then you get the problem of two batteries in parrallel charging each other up

or

do i have the normal battery for the radio and "cut" the red core from the speed controller to the receiver letting the motor battery power the speed controller

 

god, slopeing is much less problematical

 

help

please

taa

[Veron Impala gets a dusting off]

hi

when you say " big impala" is the whole plane bigger or just the wing?

i used to fly an impala when i was new to sloping in the mid 70's

i also had a "big wing" for it aswell. this was another kit

so I had a standard impala with a larger wing

Taa

[Slope soaring sites near a camping site - help pleasee]

callow bank is now a thing of the past

It was a great site for nearlly 40 years but now the current farmer does not want anyone there

he has stuck large fence posts in all over the bank ,,,dozens and dozens of them
