New Typhoon MkII

[Hill Hobbit]

Had 2 hrs+ in 30mph on Saturday with the Forza, then 2 hrs yesterday with my 10 year old Typhoon in 10mph with crazy thermal activity. Lots of very high speed hooning both days!
Bring on the Toccata asap!

 

[Hill Hobbit]

Gotta say I’m pretty exhausted today after going for it big time!

Well my patience lasted almost an hour. Ordered the yellow checkers Forza from Aloft which will bear a strong resemblence to the yellow with wavy checkers Magnus I'm building now. While I was hoping for a 2M, that may have resulted in having two gliders that were too similar. This should make a nice pair of slopers that can cover a lot of wind conditions.
The Magnus has a nice setup sheet, but the Forza doesn't have one posted. Is there a setup guide for throws and CG on the Forza?

Hi JJ - Forza setup is here and the instructions for the Schwing which is pretty much identical except for the Forza is newer and easier to access at the back

Let me know if you need more info.

Cheers,

Doc..

Good move going to the larger ship! The Aloft sales page list the CoG at 90mm. What more do you need? Set the flaps for 90° or as much as you can. Elevator 8mm, Rudder for all you can get (max 45° each way). Ailerons 30° with about 30% differential. Test fly and make adjustment from there.

Regardless of the values do use solid mechanics in your build.

Wayne has one, he might be persuaded to publish his numbers. Please remember this is all predicated on personal tastes. None of these values is set in stone.

Thanks for the info. I've designed quite a few planes and was a test pilot for several powered combat planes so I have my own techniques to dial things in, but I like having a starting point. In particular, for gliders I like to know the most rearward CG point before it tucks. I use that to determine my fixed nose weight, then add more as needed from there. The aileron throw differential is good to know so I can hopefully eliminate the need for rudder mixing.

One thing I wish that hadn't changed for this glider was the name. Forza sounds like a car made by Fiat (Fix It Again Tony). I took my Private Pilot flying lessons in Aurora, Illinois, which is the fictional home town of the Wayne's World TV show. So for me the glider name is a Schwing.

If I take both gliders to a slope (Magnus and Schwing) and anyone asks about them, I'll be able to say, "They're both nice gliders, but my Schwing is 13" longer than my Magnus!"

Party on Wayne.

Epic post... we're not worthy

I too have had issues with Aeroic nomanclature, I think we all do.

Aileron differential and CAR are speed dependent settings. These change day to day, hour to hour and slope to slope. But generally the Aeroic vertical tail volume is more than adiquate, there are a few exeptions, so things don't change too drastically..

The Forza's long name was Stormbird as it was originally the replacement for the Typhoon and originally had a 2 meter span with plans to eventually offer it with a 2.5. When the 2.5 came out, Doc added to the name calling it the Stormbird Forza, and now just the Forza. There you go, quick history on the model. You can call it the Stormbird if you like.

Wayne,
If the bird is near your desk can you provide your set up values?

 

[Wayne]

LOL - Seems like that would be easy, but I have not yet programmed it into my new Tandem radio, and think my old radio was given to a local kid, so all is lost until I reprogram and test fly. But nothing all that special as I recall. The Corsa settings should be nearly identical as the Corsa was a very similar 2.5 meter wing at the time of that writing.

 

[Hill Hobbit]

Without measuring throws etc, right now I can only say that on my Forza I initially had the CG at 100, then settled on 102mm from the l.e. It requires a gentle push for inverted (is definitely not neutral), stays in a vertical dive with no pullout and no tucking, and is one sweet plane to land. A good choice.

 

[Wayne]

Sounds perfect to me..

I generally have a slight pull up on a dive, and people that fly my planes complain that it is too tail heavy. If I'm going to lend a plane to someone for flying all day or an event, I usually add a bit of nose weight for them, and let them adjust how they like.

No he can't. Zhou is stil bootlegging the 2M version, the bloody thief.

OK!

Peiple are still acting like ther was no information given, so I guess the files I sent with my last post didn't go through, so here is the setup:

Forza setup values:

• Dimensions in millimeters
• Angles in degrees
• Measurements from inner edges

Parameter: Value:
CG *90mm from LE

Position up Position down

• Ailerons +10 -8
• Elevator +5 -5
• Rudder 45º 45º
• Flaps +2º -80º or more if you can get it.
• Snap flap -5

Butterfly:

• Flap -80 º
• Ailerons +5
• Elevator -5

*Note: CG start position is 90 mm – this is very conservative.
Please do not glue in all of the nose weight until the model has been flown and the CG adjusted back to the pilots preferred position.

Doc.

Most of my ships have two preferred CoG locations. One for smooth coastal air and another for more turbulent inland slopes. This and I like to see my CoG move aft a bit as I add ballast.

 

[Doc J]

Actually, JJ if you want the updated settings the best person to talk to is Jonty - "Hill Hobbit" on this forum.

Jonty has a 10-year old Typhoon, and I think about a year ago he got a Forza. He is a great pilot (Thats why he has a 10 year old Typhoon) and is well known for hooning around and wringing the models out on the slope - Jonty will have the latest/best settings, but they probably wont be conservative.

Doc.

Well, the instructions Doc sent said Schwing so I am calling it my Schwing no matter....

And it sounds like 100 to 102 is the magic CG reference for initial nose ballast. Will probably test fly at 95 initially, bit I prefer an aft CG unless things get windy and turbulent, in which case I toss a little tungsten putty in the nose.
But all that is weeks away.

Nice that we have some gliders with enough character and performance that people really care about them.

Noooo....anything but that...why not call if "Fluffy"

Crikey I'll have to really write the instructions now...

And...as if by Magic... I did.

Thats because The King's English is not your native language, Konrad. You speak 'Mercan.

But me?...hot damn, I not only do speak the Kings English, but I'm also phenomenally gifted at spelling and grammar, and my diction is...well Byronic... and if you believe that, well...

I like nomanclature a lot - is it similar to nomansland, or possibly an ancient term for an unmarried male?

You never cease to amaze me...

JJ, might I suggest you start at 98mm, it won’t bite you at all at that CG.
I bought mine on September 1st 2020, and it was maidened, I think, the second week of November. I’m pretty sure mine was the first Forza flown in the UK, it was definitely the first sold by T9. One thing I did when fitting it out was to use a normal 10mm thick servo for the ailerons (with blistered covers) rather than the recommended 8mm, as I always have doubts about gear strength of tiny servos used on primary control surfaces at very high speed.
The wing servos are in Servorahmen bearing mounts, with conventional clevises and 2mm stainless threaded rod. I have modded some carbon blistered servo covers to use the blisters as shrouds over the clevis exits on the wings, making it very quiet even at really high speed.

Doc, you are too kind!
