Ditch the Expo

Lads, if you want to fly one of these under control, then no expo

Set the ailerons, and elevator to about 5mm up, 5 mm down, then fly and make up your mind

You may even reduce these throws, once you have flown

Was it outdoors ?, in a shed or garage ? As white stuff is generally

Aluminium Oxide

Trouble is, that leaves a pitted surface

It is likely just the inner casing, and not involved in the running of the motor, where the powder originated

Check with 4max on dismantle

Hi.I am fitting a Laser 70 4 stroke engine in my Tigermoth inverted.Does it matter which way up the carburettor is fitted,ie needle valve at the top or bottom?

Olav, Kevin suggests that you post your question on the Laser thread, where it will be seen

Cliff, any idea what make / model that twin is?

I am on the lookout for something like that.

Looks like a Seagull Twin Comanche Simon

Thread: Best way of drilling fibreglass and carbon fiber strips?

Masking tape, sandwich with plywood sheet and firm support on the drill bed Chris

Assuming the area is flat

Masking tape, one layer, top and bottom to prevent scratching

Then thin ply, top and bottom, G clamped the the drill bed

Nice sharp drill, set to highest speed

Then don't punch it through, but gently allow the bit to make its way through

Ease the bit through allowing this to cut

In the olden days Fox, we just fitted one shaped u/c wire down, longer than the prop, even without a wheel

Just to save the blade

You can barely see this in the air

Martin, receivers are so small and light nowadays consider fitting it in the clear

Two of my models have the receiver in the canopy

And just as revision

Microwaves are line of sight reception, so any metals are a shadow or barrier to these,

Though we always compromise with the best fit

Thread: Charging rx packs
21/06/2019 13:34:43

No more overnight charging Martin, Nihms cannot tolerate overcharge and heat without damage

An auto charger will charge and switch off at the right time

The numbers you need for supervised charging are obtained by

Your charger output, with ref to your pack capacity, that you don't mention

Thread: Heli clutch advice
20/06/2019 14:25:26

You know the clutch unit could be near 20 years old Jon

Though looking at the lining, it was virtually new when last used

Again, my comment, that a novice tempered that brown and blue on the steel

With multiple tentative lifts

It looks as if that assembly barely flew,

Posted by Denis Watkins on 20/06/2019 07:30:48: So rebind with the throttle down

Denis, I am sure you meant to say initialize (the esc) with the throttle down. Binding is the process of connecting the Tx and Rx, and has nothing to do with the throttle position. This to clarify it to Daire.

Thanks Max,

We do try to explain so much in a few words

It is simpler to do than it is to explain

20/06/2019 07:30:48

Just to add, while the lads prepare to answer Daire,

Take the prop off, it will harm you indoors

Your failsafe is upside down, throttling up with no signal

So rebind with the throttle down

If the motor still springs into life on switching the Tx off

Then reverse the throttle

Your battery pack does appear adequate size at this point

Dont go spending yet

With respect to the owner Jon, this usually happens with the novice, just lifting then not, then lift then down.

The metal linings work by friction

Less obvious wear with the accomplished heli pilot

As they fast idle to get the motor warm, then smartly into the air

So far far less slipping

Wow Nigel

You have been ahead of the game from the start of this project, and there is the result

Don't skimp on the horizontal stabiliser

There is no need for a weight saving surface on this one

The horizontal stabiliser is subjected to huge forces, so build it rough and tough

Lads ??? Lads ??!

Your opinions and posts make this forum worthwhile, and helps keep my sanity !

You two are both sides of a very vital discussion coin, selfishly, my continued education

Please continue my daily upkeep

At most shows the " groupies " sit just along the fence, with none standing unless, flyer, spotter or Marshall

I am sure this was a over site this time, as at previous shows at Weston, the pilots could clearly be seen during there spot

Thread: Elevator joiner wire plastic tube bearing
18/06/2019 17:55:18

The elevator has to move, and is typically shaped either by a radius or a " V " with very small gap

It is your build, so offer up the work to test for full movement without an appreciable gap

As surfaces work best in air with no gap

The final covering will seal any gap

But set too close, the elevator may not be able to move

Test it

Thread: Seagull Turbo Raven
17/06/2019 21:31:40

A good OS55, as they had some problems, will exhilerate the Raven

The 91fs, is more akin to a bigger more flowing model, Astro Hog, big Cub, Warbird, World Models Super Sport,

XL, Wots

17/06/2019 20:14:10

Glen, you already have the OS55AX, that the turbo was made for

What are you looking for

Do you have a difficult airstrip
