Sukhoi Pak Fa T-50

Hello everybody,

I would like to open this topic for the new Sukhoi Pak Fa T-50 model.

There is a topic about the birth and evolution of this model, prior to releasing it on the market. You can view it here:
http://www.rcgroups.com/forums/showthread.php?t=1431834

Hopefuly by Wednesday I'll be able to finish the MK2, that will be up for grabs.

Few details about the kit:
- XPS high quality foam
- Vivak cockpit
- Wingspan - 850mm
- Fuse length - 1220mm
- Twin 64mm EDF (or pusher prop)
- Empty kit weight - 280gr range. I'll post exact measurement of the MK2 as soon as I'll have it
- Price - 35 euro

This kit, continues the Podium Jets idealogy. It is an easy to build platform, that offers the builder many possibilities. The PakFa structure, is a step beyond our Mig 29 kit, since it benefits from way more experience. To make things even better, the PakFa's unique shape is an even easier build, that gives you even more building options.

In this topic, I plan to make a short "how-to", that will hopefuly benefit from all the customers, different building ideas.

For the finish:
The link of the second flight video, and few pictures:
RC Sukhoi Pak FA T-50 (6 min 10 sec)


Thanks for watching,
Mitzu

Interesting ... how much will be the shipping to Poland ?

Are you planing to make a EDF with moveable wings (open for glide/landing) and delta (for high speed) .. like some advanced F-18 have ?

Hi guys,

Thanks for the nice words.

e_lm_70 - The coust would be roughly 15 euro to Poland.
I don't understand your question related to the wings. The PakFa doesn't have moveable wings. It's fixed all the way. Even the F18 has fixed wings. You mean something like the F-14? If so, no I won't give it moveable wings. I'll keep it like the real aircraft.
At least, this my understanding of your question. If you meant somenthing else, don't hesitate to ask.

Take care,
Mitzu

Sorry I confused which model has original moveable wings and which not.

So my question is:
Do you have plan for an F-14 with moveable wings ?

Or a Tornado with moveable wings? ...

Thanks

Hello,

Not in the near future. Maybe further down the way.

Take care,

Thanks

Yep, worldwide.
Australia is arround 25-28 euro per model.
If you want fast EMS, that's arround 45 monopoly money. (euro, that is).

You can check out my Mig 29 here
But, the Sukhoi is a much much easier build. Tomorrow I will start posting pics on how to build it. But as I said, very simple, like Lego.

When I started Podium-Jets, I had few things in my mind:
- design kits that are very easy to build
- design kits that you can't go wrong with, no matter how unskilled you are as a builder
- design kits that offer a large spectrum of posibilities
- design them to be semiscale/scale
- design them to be the cheapest

I think I succseeded in all these steps.

Though, this is way different then China models. This is a building kit, not an ARF kit.

I would go for a building kit for reasons like (personal - subjective- reasons):
- you don't buy electronics that you don't need, or that work just few flights
- you either way have to work on ARF models too. Usualy they need some tuning, strenghtening here and there etc.
- if I'm up to modify something, I prefer this BlueFoam rather than EPS
- I have a lot of fun building it, and when it flies, I know it's me that built that plane. That makes it special for me.

The minus is, that in order to get a surface like on those models, you have quite some work to do. Panel detailing, riveting, painting etc.

So, it's a plus/minus situation.
It's your option.

Take care,
Mihai

in the mean time, you could get a 64mm Tornado from places such as Nitroplanes.com . they have a pretty nice one and not too expensive. I'm sure there other vendors, but that's one that comes to mind.

Hi guys,

I'm 80% finished with the job. Unfortunately these small modifications that had to be done, turned out to be more complex, since every small detail is linked to some other detail, and so on.

I also changed the whole canopy. Didn't like the shape of it, and also I didn't like those warbird like pannels on it. So I've made a totally new one. This took most part of today. The pannels are now scribbed in. It looks way better.

I've remade the whole thrust tube. Added abit more place for the LG (if desired), I also had to enlarge that area of the tube, since it was just too squeezed.

But while I'm here, I was thinking about the landing gears. There would be an option, that I would cut out the bay. People who want to fit retracts, will take that part of foam out, and install them. Those who want it to belly land, can leave that foam in there.

My main problem is with the sizing of the retracts. For a rotating sistem, the wheelbay should do the job for a 48-50mm dia. wheel. As for the pivot bay, where the retract is fitted, there I'm not sure about the measurments. There are those 33 by 35 and 44 by 40, or something like this, I don't remember exactly. Don't know wich one to go for.

In the attach you have the 2 slices. Basicaly the retract will fit between these two. The first one is the wheel bay, and, 100mm after, you have the pivot bay. This means the whole strutt/wheel assy shouldn't be longer/taller than 100mm. If so, then it would probably need some dremmel to go on the other slices of foam. I can only cut in 100mm batches, so.

As for the front wheel/pivot bay I'm abit affraid of the battery pack. The foam thickness is 10mm. I could go over that, but, just don't know how much. I have spare room of 68-73mm over this 10mm thickness.

I would highly apreciate some help from those of you who wanted this option in.

Thanks in advance,
Mitzu

What is the area of the narrowest portion of the duct?

Could you post a side profile from the two cross sections you posted?

I'm not sure if you are limited to creating the mount to scale. A cheat that both the F-35 and T-50 use is angling the strut forward. This allows you to lower the mount to obtain the necessary height, while still remaining under a strut length limit (in this case your 100mm).

The pop out that you mentions would be useful to custom possible differences.

Common Etracts for 2.5Kg AUW.

ChangeSuns Retract
Width X Mount Depth X Length
17.6mm X 21.4mm X 65mm

Mount Plate
Length X Width
32mm X 36mm

PZ15090 Retract
Width X Mount Depth X Length
17.8mm X 23mm X 66.7mm

Mount Plate
Length X Width
33mm X 35mm

Eflites 10-15 are similar.

100mm? From the trunnions pivot point or from the top of the retract mount floor?

Will the empannage be 12mm thick?

As for the forward Nose bay, You have the battery mounted thru the canopy which is why the 10mm of foam?
I add 1/32 ply or hard balsa with holes in it in situations like that.
If you do the same cut out as you suggested with the main would be useful.

Is it hollowed internally from the canopy to the lower ordinance bays? Or solid foam?

And one last question, till the next post, what's shipping to Ontario, Canada?
I can't help but give it a try even if it takes a few years

Hi guys,

After some playing, it seems it can take the retracts.
I did some trials with the ChangeSun, because that one is a bit bigger. If that one fits, any other smaller LG would fit.
I think it's doable, so I'm gonna start more detailed work.

What I must say before this, is that it will deffinetly require some dremmel in the other slices too, dependig how tall you want the plane to stay on the wheels. Even if do the cuts, it will still require some ammount of work: plywood inserts, fitting, etc. There's no way I can do this as a just click in sistem.

It will only work with rotating LG sistems. If you go for straight ones, then wheel size should be smaller.

So, delay again, but hopefully, it'll be a better jet in the end.

Maxthrottle:
The smallest size on the intake, at this point is 32.90 square cm. A circle with 64mm diameter has the area of 32.17 sq. cm.
Though, I will have to increase the sqeezed area. So probably at that junction, the tube will have something like 30 sq. cm. Still, it will be ok.

Shipping to Canada would be roughly: 15-20euro. I still don't know the package's full weight.

Take care,
Mitzu

That is just excellent

So when will you have these Jets ready? Are they ready for purchase/pre-order on your website?
