Well done - you'll be a shoo-in for the A. The 8 does not have to be dead accurate, just a reasonable attempt, and at a fairly consistent height. I find it's best not to make them too small to give you time to adjust, and to make the crossover fairly nearly at 90 degrees to the other leg. That forces you to make the circles fairly wide and gives you more room to get them consistent.

And yes, the rudder is a bit of a forgotten control if you fly with ailerons - as most do. I've got a 1/4 scale Auster that needs rudder in the turns, and a couple of twins that benefit too - but you can mix that in on the radio.

Rudder is most used on takeoff - otherwise the prop effect can take you all over the place - DAMHIKT. (Took me a while and a close encounter to get better at the rudder).

So well done on using rudder on the approach to keep it straight.

Cheers Andy

I need to use the rudder since I'm just putting the finishing touches to a cheap Chinese 3 channel v-tail foam/ply eagle thing that my daughter bought me for fathers day. It's taken me ages to get the the surfaces moving in the right directions, you'd think it'd be easy but I could get either rudder input movement correct or elevator correct but not both until last night.

It'll be interesting to see if it flies since I struggled to the V aligned equally.

Have been working up a plan for a smallish span kit scale model - there'll be a build thread over on HPA in due course...

Finally. Some decent footage of my Lacey M-10. Last time out the nose-button had worked loose and wreaked havoc with the behaviour. Unsuprisingly. Nose button down and right thrust reset and is now held with epoxy.

For those who need to know. Motor is 2 strands 3/32", 16.5" long. Turn counts were 1200 (42s, ROG) & 1300 (46s, ROG). Gives a decent altitude without having to worry about hanging up in the rafters.

You're cheating. The string you've got fixed to a nail in the centre of the floor is so fine that you give the impression that the model is trimmed to fly in just the correct radius circle to miss the walls by about 300mm.

Ahem. That's bloody impressive. Beats anything I've ever built. Chapeau, sir.

No, just different. I couldn't build or fly a multi-engine oily job with n-channel RC where n = lots whereas you used to without thinking twice about it.

When you get your aeromodelling mojo back you'll find that your VMC SE5A will make a good indoor model.

This is one of the blokes trimming out his VMC SE5A yesterday.

It's a bit stally at the moment but it's fresh off the bench and the iffy launch didn't help the flight either. When he's sorted it, it too will fly ROG as well or better than my M10.

Oooooooooo. Wonder if I can get mine to do that?

Hello!

I follow this thread with interest; I was an aeromodeller in my 'teens. I'm impressed by The Lurker's video. Well done.

I have a query: it looks like there are scratch builders here. Where do you get your materials? I remember using very thin birch plywood in high stress parts of structures. I am currently working on a project (that has absolutely nothing to do with flying!). Very thin (about 1 mm) ply might be useful. But I don't know where to look for it! If a any of you can tell me of a good web-based materials supplierI will be very grateful.

I generally use SLEC (https://www.slecuk.com), but Balsa Cabin (https://www.balsacabin.co.uk) also have a good reputation.

I tend to buy stuff in quantity to minimize the post and packing overhead.

This really should be in a the "not really a rant" thread, but it's a bit niche for there.

Now, if I'd managed to finish this last weekend or even, as originally planned by the end of Dec., then I could have test flown it yesterday, but I didn't so now I'm sitting kicking my heels waiting for a weather window that coincides with some free time. Grrrr.

andytheflyer · « **Reply #138 on:** 11 February, 2020, 09:16:19 am »

Now if you'd have put an OS52 4 stroke in it, you could have gone flying in Storm Ciara anyway.

I just happen to have one of those engines on the shelf, doin' nuttin'..............

(Alternatively I can offer you an OS56 alpha, I've got 3 of those going spare.........)

That's what the right hand (or LH) stick is for - you don't have to push it all the way forward.....

Some of these works of "art" are mere bodgery. I am in the annoying and deeply distressing situation of having to add _tail_ weight to the Pichiatello. Yes. Really. _Tail_ weight. I really don't know _where_ to put my face. For those of you looking for a little Sunday Night Schadenfreude the whole sorry debacle is on the build thread at HPA. Pages 8 & 9 refer.

tl;dr - Tail weight needed, but wing loading and AUW likely to be OK so not an utter disaster, but still too shaming for words.

I'm appalled. Tail weight?? Tail weight?? How did you manage that? You really do need that OS52 up front. Then you won't need any tail weight............

RIAT cancelled.

However they're still flying U2s & B2s in and out. B2 taking off right over the house this morning. V. unusual as most take-offs and landings are, unsurprisingly, on the main runway line which is (more or less) E-W aligned and for landings they're usually lined up from tens of miles out. Mind you we do get the odd landing where the base leg is over the house. As I said quite unusual.

That's Agent Orange (aka POTUS) ordering an all out offensive on those great big orange virusy thingies, them with the blue knobbly bits.

Wouldn't like to be in their shoes (the virusy things) when the (the B2s etc) find them.

As a distraction from the fact that the weather is near ideal for flying and no bugger can fly at all a Walt Mooney Cook-Up is being run on HPA. I chose to do his peanut scale Chiribiri No. 5. This means spoked wheels, it also this means small spoked wheels, i.e. 13/16" dia. or ~ 20mm in new money.

I have never built spoked wheels* wheels before. I think the most complimentary thing one can say about my first attempt is that it will be usable.

For your amusement.

Wasn't sufficiently satsified with the 1st, went back and redid it as well as its mate. Still a long way from perfect, but I can live with these.
