|Thread: What's flying over your house|
Greetings from up the road Nigel
Those Galaxies are a pretty impressive sight and an amazing piece of hardware.
|Thread: Warbird Replicas Bf 110 club.|
The inboard exhausts on the starboard engine are placed underneath the wing to provide uninterrupted airflow to the supercharger intake. This arrangement was not repeated on the port nacelle, where both exhausts were positioned above the wing.
|Thread: Hobby King Venom|
Yip yip, the Vamp makes a neat sloper. You can fly it as is with some EDF back up. Or, if you want a bit better performance, or your slope is a bit iffie about liops, you can make a dedicated sloper by blocking off the intakes - like so (maybe paint the intake covers black though):
Might pay to wait until you get it and see how tough the tail booms feel as they have been strengthened in this version - HK does occasionally listen to us.
"Although the initial version of the Vampire was a very stable flier Durafly have tightened up the tail booms and elevator with carbon fiber support to give even better control."
|Thread: Forum members' new models: Let's see them.|
Thanks for the link Mark, awesome work and pics.
Yes the trick with painting film is to roughen it up a bit first with steel wool (gently) and then give it a coat of primer. Tamiya make a very nice primer product for plastic and their acrylic paints adhere well to it.
Here is my DH-1 painted up.
Yes Mark, a very nicely presented SPAD - would love to see a shot from behind if you have one handy.
|Thread: Mike Trew ASW 20 (Traplet)|
Thanks for the link to that website Mark - quite an interesting one to wander through, if only for the colour and decoration ideas.
|Thread: im not sure what to make of this|
This looks like fun too - take-off is at 3:30.
|Thread: Mens Sheds|
A local club has done just what you suggest having used some club funds to build a shed for storage and as a gathering place for building sessions and to act a focal point for club members to hang out. As with most clubs, they have a membership "of a certain age", but actively encourage younger members and the shed also comes in handy for this too.
|Thread: photo size|
Actually, you don't have to worry about resizing photos now as there was an upgrade done a while back which allows larger vids and pics to be loaded and the system resizes them for you.
The larger pics take a bit longer to load in your gallery, so just be patient.
As an example, this pic was 3000x2400 and 1.2megs - when loaded here it was reduced to 1024x768.
|Thread: Zagi Bash 2017 - Slope Combat Competition|
I'm all tooled up ready to go
|Thread: Measuring thrust angle?|
You might be overthinking this Tony - just whack in a couple of washers and go flying.
One trick you can pull if you have a model that climbs significantly under power is to turn the climb into a spiral which has the effect of reducing the lift created by the wings and will avoid any stall while keeping the model in close proximity.
|Thread: 15th September|
Mention could also be made of the Hawker Board of Directors who, in early 1936, had decided, in the absence of official authorisation and at company expense, to proceed with issuing the design drawings to the production design office and to commence tooling-up for a production line capable of producing a batch of 1,000 Hurricanes. This action resulted in an additional 180 Hurricanes being available when war broke out.
|Thread: Sigma EQ Twin/New Lipo Balance issue|
You are welcome Mark - good find on that link!
Just to recap on the single cell charging.
Say you have the following (3S):
Balance lead wires:
You would charge/discharge the individual cells like so:
CELL1 = BLACK/BLACK & YELLOW/RED
CELL2 = YELLOW/BLACK & BLUE/RED
CELL3 = BLUE/BLACK & RED/RED

Hi Mark, it is unusual for the lipos to get out of cync straight out of the box, although the"four button charger" you have does tend to do this.
These chargers work by having a magic number of 12.6v set (for 3S) as max charge and, once this is reached, they see how the balancing is going. As you noted, the cells had an aggregate of around 12.6v when you stopped the charger. The reason it had been charging so long is that when the charger has a look at the cells and sees one overcharged it starts a discharge process to bring the overcharged cell (the one at 4.24/6 in your example) down to a level where it can start charging all three cells again to bring the whole shebang back up to 12.6v. The discharge process isn't very efficient or fast, hence the 3hr time taken on your charge.
The only quick fix for this (apart from buying a more advanced charger) is to charge/discharge the cells individually once the 12.6v threshold has been reached. You don't have to do this every time as it doesn't really matter if the cells are a little out of balance. So, in the example you gave above, you would discharge cell 1 down to 4.2v and charge cells 2 and 3 individually up to 4.2v. Bit of a pain, but once balanced exactly you might get 4 or 5 cycles out them before they need adjusting again.
To do the individual charging you need to make up a harness with a two pronged pin which is used to charge the battery through the balance lead. I'm "busy" at work at the mo, but will see if I can find a pic on line later.
EDIT: Just a note while I think of it - when charging the individual cells you have to set the charger up for single cell charging as opposed to 3S.

|Thread: Youtube, Vimeo and Photobucket videos|
Just go ahead and load it at 560x315 John. The system seems to cope with that OK.

|Thread: Swastika decals for FMS Stuka|
Due to the dark colour on the FMS tail, it really needs a white border. Tricky, but not impossible.
That's interesting - FMS must have physically omitted them as they do come on the decal sheet.
|Thread: New 78" Vulcan for twin 90mm DF|
There is this one **LINK**
|Thread: Glossary - your forum needs you!|
Really enjoyed reading through the Glossary - a lot of great stuff there.
There were a few basic things I noticed missing and I wonder if they would be worth adding to aid some relatively inexperienced readers. Here's a few notes I made:
Camber: when activated the flaps and ailerons all drop down a few millimeters, all together and by the same amount. The result of dropping the entire trailing edge of the wing slightly is to increase lift without increasing drag too much.
Crow braking: also called 'Butterfly braking', this wing function is used when landing. When Crow is activated the flaps drop down and both ailerons deflect upwards, all at the same time. This gives a very effective combination of drag from the flaps and reduced lift from the up ailerons, now acting as spoilers
Decalage: term used to describe the relationship or angle between the main wing and the rear horizontal control surface. Commercial measuring devices are available from model shops to gauge this.
Dope: a type of paint or sealer used while covering aircraft, there are two types - Nitrate (not fuel proof) and Butyrate (fuel proof). Nitrate dope can be painted over Butyrate dope, but Butyrate can not cover over Nitrate.
Fan swept area: the internal area of an EDF shroud, less the spinner area. The EDF influx area should equal the FSA and the efflux area should be around 85% of the FSA.
Incidence: the difference between a surface (wing) being parallel to the center line of the aircraft and a wing offset from the center line. If the front of the wing is up, its positive, if down its negative.
Pitcheron: wing type where a model uses a separate servo for each wing (both of which are fully moving) using a delta/elevon mix. Both wings are driven together for pitch (there is no elevator) and in the opposite directions for roll.
Reflex: this is the opposite to camber and when activated the flaps and ailerons all move upwards slightly, in unison. Changing the airfoil in this way results in the model becoming more 'slippery' through the air, hence you get a slight increase in speed.
Spoilerons: a control surface that performs the dual function of ailerons and spoilers. Like flaperons, spoilerons are on the trailing edge of the wing, but move upwards to 'spoil' the lift to assist with landing. They are activated by a switch on the transmitter and require an elevator mix to keep the model stable in pitch.
Tailerons: in this set up (which is often used in jet type airframes) the model is controlled by two all moving horizontal stabilisers. These are also referred to as stabilators and are set up with an elevon mix and provide pitch and roll control. The main wing on the model can be set up with or without ailerons.
V-Tail: often used on gliders where the model has two rear stabilisation surfaces in the shape of a V. These work together by way of a movable airfoil at the trailing edge to give both elevator and rudder response - often referred to as a ruddervator. When setting up the rudder movements, the surfaces must move in the opposite direction to the ailerons. The elevator function works in the conventional way.
VTPR: Voltige Tres Pres du Relief - a French slope soaring term that has gained worldwide use and translates as "aerobatics very close to the ground". Models have been designed specifically for this part of the hobby and world champs have been held.
Wingeron: wing type where the model uses one servo to drive both wings (which are fully moving) in opposite directions to control roll only. The model has a standard elevator for pitch control.
Mmmm....... getting writers block now. I think that will do for the mo
