When removing covering film to attach stabiliser or fin, use a
soldering iron to melt the film away. This stops a blade digging
in and weakening the wood.
For MPX MC3030 users:
The strap hangers you can buy for this radio do not give a
very good balance to the radio. I have an alternative method
using 6mm aluminium tubing available at hobby and DIY stores.
I think the pictures give enough detail, but if not get in

For those who use air cans for airbrushing, there is an
alternative if you already have a 12 volt compressor for your
car tyres. Using a 2 litre soft drinks bottle as a reservoir and
fish tank fittings available at most pet stores and the
compressor, you can make a unit which will provide enough air to
run your airbrush. I set my compressor to about 35 psi and that
runs my Badger airbrush.

Foam Cutter Power Supply
I use a dimmable transformer for low voltage lighting
controlled by a dimmer switch. The transformer I have is 105VA,
but 150VA might be better and give an easier control of the heat
Cheap Wheel Collets:
Use a strip of terminal strip, cut off one "set", remove the
plastic coating and split the brass between the screws using a
dremel or hacksaw. Cheap and you can use a normal screwdriver
instead of an allen key
(6) If your clevis won't go
through the holes in your servo arm or horn, apply a small
soldering iron to the back of the clevis and gently squeeze the
clevis. It will slowly melt it's way through and if you turn the
horn gently will produce a very nice, snug fit.
(p.s. ONLY works with metal
Cautionary Tale from the Club
Corrosion: Until last Wednesday evening this was only something I had
read about. I launched my large electric glider and it set off happily
towards the entrance gates. It then demonstrated a disconcerting lack of
response to control inputs and continued in a gentle descending right-hand
turn towards the car park. It just missed the cars and crashed into a tree
from which it was fairly gently deposited on the pavement. Lucky
On examining the electrics,
I thought that my soldered joint between the negative battery lead and 4mm
socket had failed, but on cutting off the socket I found that the whole
wire part of the lead had been reduced to a sorry black mess!
Perhaps in pre-flight
checks, we should include a jiggling of the black lead?"
