Hi,

Since you've both flown your Formosa, do you have any new recommendation on the CG and control surface movement for the ailerons, Elevator and rudder.

The instructions give a wide range and I'd like to stick with "what works".

Thanks for your help.

Hi Wayne

I set the ailerons for 2cm (20mm) . If you do not have dual rates I would start at 15 mm and increase it as you get comfortable. I set my dual rate at 70% of the 20mm for take off and landing and use the full 20mm for flying. It rolls like a top; can't imagine what 30mm is like.

The elev is also set for 20mm but I use all of it as it is not as twitchy as the ailerons.

The rudder is set at 30mm and I would not reccommend mixing it with the ailerons. 30mm gives plenty of rudder for hammerheads and knife edge flight.

I set the CG at 95 to 100mm behind the leading edge. It flys more in a groove at that setting.

Good Luck

Hi Donwojtas,

Thanks for the info, I'll take your suggestions and use them.

The throws did look like they were an awful lot and I was a little concerned for my first flight. We got snow last night and it looks like there will be no let up for a while, so I don't know when I'll get out.

I'll let you know how I make out.

Best regards,

Wayne Miller

Which speed control are you using for 3 cell?

Donwojtas,

Which speed control are you using with the Astro 010 and the 3 cell Lipoly? It isn't clear from the documentation Astroflight provides that it is safe to use the 3 cell Lipoly although they claim you can.

Sorry for the delay Tweet

I am using the Castle Creations Phoenix 25 with the Astro 010. The Phoenix 10 would work but the BEC can not be programmed plus I like to have extra capacity in the controller in case I upgrade to a larger brushless.

Good Luck

Don

Hi Don,

Thanks for the reply. FYI I think the BEC can be programmed with the Phoenix 10. I just got one and plan to use with a Formosa or something similiar to practice IMAC stuff at my house.

Take care.

Thanks for the updateTweet

Most of the documentation on the Phoneix 10 I have read in the past did not mention being able to program the BEC. I just checked at NES and its write up on the Phoneix 10 indicates the BEC being programmable. I wonder if it is a new model or just not being described properly in most of the older spec. write-ups. In any case I learned something new.

Hi Donwojtas,

I finally was able to get out with my Formosa this week, there was very little to no wind.

With your CG and control surface setting advise, I found it flys very smoothly and I would easily compare it to a stable, larger glow pattern ship as far as the way it performs.

I have a AC MINI 1215/12 with a GWS 350 "C" gearbox. The prop is 10 X 4.7, with 1050 KAN NiMh batteries. I have some 2 and 3 cell LiPo's coming this week and expect better performance with the lighter weight.

I had the Airlerons set at 2cm with 75% expo. Full throw causes very quick rolls.

I'm very pleased with its performance as is, without the LiPo's and would recommend it as a nice transition to electrics ship for any experienced pilot.

I've also built a couple of "foamies" - SPA3DX (spadtothebone.com) and a 3DX (foamyfactory.com) with the free full size plans from the web and will be using them for my "fooling" around planes. They are cheap, quick and easy to build.

Thanks for all your help.

Best regards,

Wayne MIller

Hi Wayne,

Glad you were finally able to fly your Formosa. Sounds like things worked out pretty good. You will really love it with the 3 cell lipoly as loosing a few ounces really improves acceleration and vertical performance. I believe your motor is stronger than mine so a 10-6 or 10-7 APC prop would really spice things up. I will be going out to fly tomorrow morning. We have had a lot of rain lately so its been a couple of weeks..

Thanks for the update.

Happy Flying

Don

This sounds like a fun airplane. Mine should be here next week. Also have an astro flight 020 direct drive that needs a home. May try it with the stock setup for a while then see what happens----

SJN- That is the wildest paint job I have seen on a Formosa.
David E.- The Formosa seems a llittle anemic in its stock form. Running 3 LiPo cells will really perk the stock motor up but will shorten its life. That astro 020 would probably rip the wings off. There is a Formosa ll out now (43 inch (109 cm)wing span) that would be perfect for a geared 020.

SNJ...please tell us what brand, type and method you used on the Formy in your post...that is an outstanding paint job.
Here is mine in stock drab...will maiden with TP 1320 3s and C gearing with 9/7 sf. I am glad I found this post because it will make the maiden a lot les unknown...about the c/g and throw rates and all...thanks for the info...now tell me ..what about the paint you used...!

Thanks guys.

I just used normal Humbrol hobby paint, that you can buy for plastik models.
Only took about 2 hours....mainly because of the flag.
Pretty easy [8D]

The flag, was done by sticking masking tape onto a glass pane about the shape of the wing, then I drew the flag on the tape, and then cut out the bits with a sharp knife, and stuck them onto the wing....then I painted it all black, and then removed the bits of masking tape, which reviels the white checkers underneith

Simple, but looks good

Hi Donwojtas,

Just an update.

I've been flying my Formosa for quite a while now and I'm very pleased with the aircraft.

I ended up with a Model Motors AC Extreme 1215/12 mounted on a MPJ 8000 gearbox with a 5:1 ratio and the GWS 9X5 "square" ended prop which is more than enough power for the aircraft.

I don't fly 3D and found the suggested control surface throws too sensitive, I like to fly the plane as a "smooth" pattern ship.
I fly the plane normally with the low rates shown below and only switch to high rates when I want very sensitive responses.

The control surfaces are:
Elevator:
Low Rate: 10mm up & down Expo set at 25%
High Rate: 15mm up and down Expo set at 50%

Aileron
Low Rate: 10mm up & down Expo set at 50%
High Rate: 20mm up and down Expo set at 75%

I only use rudder for aerobatics and so I set it at the suggested throw.

Some other things I did:

Install next size wire up for landing gear.
Bend landing gear forward so wheel axle is in line with wing leading edge.
Install larger main landing wheels for short grass (I use 8.5 cm ā€“ Iā€™m not sure if they are Dubro or GWS))
Install stronger magnet for canopy (I use ones from old PC Hard Disk drive actuators - very powerful)

Hope your enjoying your Formosa.

Fly4Fun,

Wayne

Thanks Boss,

I'm looking for a better motor....that will fit into the GWS "C" gear mount....


Wayne, did you say you used the GWS gear box ???

Hi Sam,

I only used the GWS "C" gearbox with the AC extreme motor (see earlier post). The motor was a little loose so I streched some thin "O" rings around the motor, then pushed the motor into the gearbox to make it tight. I had to elongate the screw holes in the gearbox a little so the screws would go into the motor.

I now run it with the MPJ 8000 gearbox with a 5:1, its a stronger gearbox with a bigger shaft that does not bend and was reasonably priced.

Hope this helps.

Hi Sam,

I always check the local hobby shop before ordering since I try to support them whenever possible. In this case their price was close to mail order, so I ordered from them, and they inturn ordered from their supplier.

I normally order my motors from ICARE in Quebec. If you order from them, get the gearbox to fit the motor at the same time. Their prices are US dollars, so you have to call them (toll free) for prices in Canadian dollars, they have fairly good prices. The motor I mentioned is here:
http://www.icare-rc.com/m-motors-miniac.htm

I also order from Hobby Wholesale (Alberta - free shipping for MAAC members)and Great Hobbies (P.E.I. also free shipping for MAAC members) and no PST.

If you are a MAAC member, check out the latest add for Ideal Hobbies on page 4, they are selling off their Phoenix Models for 1/2 price.

If I can help with anything else PM me (on bar below) and send me your email address and I'll mail you direct.

Fly4Fun,

Wayne

Its awesome with the throttle on. The only thing I dont like is the landings, with that prop it comes in too fast or stalls. Im going to get a Tp 1900 or Tannic pack so I can run a different prop
