I used these digitals on the ailerons http://www.hobbycity.com/hobbycity/s...idProduct=5502 and found them excellent (will be fine for rudder/elevator too), and I used JR DS821 (standard Spectrum Digitals) on elevator/rudder, because I had them laying around. All worked fine for this plane.

Cheers, JB

I used JR 9411SA's on ailerons. 3421SA's would probably work, as well.

I have the Spektrum DS821's in mine and they work fine for aerobatics, I can't vouch for 3D as I use other planes for throwing about.

Mine flies fine with the humble JR539s ... I got all I need there.

Four answers in 29 mins, not bad going chaps. LOL

Let's keep it up old sport ...

Regarding the incidence problem:
I've heard of one or two flying with up elevator in the UK (Wing L/E's DOWN by .5-1deg). Check/ measure the stab/ wing incidences carefully. If they're out, you have two-three choices: (in order of preference)
1. Contact the supplier and see if they will replace the kit as it's not right;
2. Adjust the wing incidences by elongating the fuz holes and then reinforcing with ply/ carbon washers; and
3. Fly/ trim as it is, though it'll not be perfectly trimmed for all manoeuvres.
The supplier SHOULD be understanding if the kit is proven to be incorrect.
Let us know.....................You're not alone!

I have been in touch with the importer who has agreed to send me another kit. Not sure if it will be just the fuse and stab or the whole kit (which would be nice). This time I will measure the incidences before gluing the stab in place. I am pretty sure that it was the stab cutout that is off. If needed I will recut the stab cutout and recover the area before mounting the stab.
I haven't heard that it has been shipped to me yet but I will report when I get it so people will know if they stand behind their product or not.

821's are fine for 3D in this size plane . . although they are a little slow.

JB

Thanks guys for all the great choices. My mentor has convinced me to buy my first set of high end servos so looks like I'm going for the JR 9411sa's.

Phewww . . . sure hope my wife doesn't read this [X(]



Anyways [link=http://www.s4a.ch/eflight/motorcalc_e.htm]eflight eMotor Calculator[/link] estimates the 16x10 on 5s will push the Hacker A50-12S to 1400 watts and 78 amps max. I'm a crazy fool when it comes to over driving my Hackers, but I'm curious if anyone has tried this in real life.



Thanks for all the great info on the thread. Makes it all much easier for those of us coming to the game late



Joe

You don't need 1400 watts of power. Downsize you prop choice. I think my combo is around 1100ish watts @60A static. It's been a while since I measured it so I'm not 100% sure on those numbers. Torque 4014T-570/15X8 APCE. Good enough to fly Masters. 8 minute flights.

Join the Electron Club at Atlanta Hobbies and you can order most of your stuff there at slightly lower prices with free shipping. Your order will probably cover all the cost of the membership.

I've got a Thunderpower 1010C with balancer for sale, $160 shipped, here on RCU. I am still keeping a few of these chargers in addition to my two new Cellpro 10S's I have.

With 1,400W you are talking unlimited verticals for sure. You calc must be showing the 16x10 at about very close to 7,000 RPM. That's a lot of power for the Angel. I think mine is only pulling about 900W WOT.

Sadly, I already ordered from Esprit, but I think you are right on the prop so I will try a 16x8 and a 15x8 just for good measure. Also, I will look for your balancer right now as that sounds like a good bargain to me. I'm only sorry I missed out on buying the Angel this spring, but I look forward to entering my next contest in '09 in NJ Thanks for alll the good input!


Joe

Don't have too much time so let me write this fast. . .

Flew with a 4s setup because my 5s batteries didn't show up in the mail yet . . . 4s on a 17x10 and an A50-12s and the graph is below.

Empty Weight (no battery) 4 lbs 12 ozs
Angel + 4s 3300mAh TP 5 lbs 8 ozs

Had the same problem regarding elevator trim as shown one or two pages back. Checked the incidence and found stab is more than 1 degree nose down different from wing.

I hate building so I always have complaints about the build, and for me I will never again buy an ARF with a pull-pull. Otherwise the quality and the flying characteristics were outstanding.


What is the concensus on incidence problems? I hate building so repair of the incidence is out of the question. Should I buy another model and hope for better, or is there something else to be done?


Thanks,


Joe

Looking back on the thread I see that others reported using up trim with the recommended CG as well so I am beginning to think the incidence issue has been around for awhile, but not heavily discussed. Anyways, I'm curious to see what those with more experience have to say . . .


Joe

See my post #306 above. Those are pretty much your options.........................
Do check your incidences carefully though, before taking any action!!!!!!! It's worth doing something though, 'cos they DO fly very well indeed. A new one can be checked "outta the box" by "dry-assembly" in a coupla minutes.
Regds, Bill.

Here are pictures of how I checked my incidence.

1) Set the plane on a table and used a level on the wings to insure I did not change the attitude during testing.
2) Used the stab as my reference line and set the laser pointer to zero (see second picture)
3) Checked the wing incidence against the zero reference line as established by the stab incidence


Result = 0.8 degrees down incidence wing versus stab.

Is what I did valid? If not what should I do differently? If yes, I guess I'll ask to send my plane back []


Thanks for the help!


Joe

Hi Sunny. That won't tell you which one is out, BUT it does tell you that one or other is not correct, and so is valid as a check. Apparently they should be "zero-zero" according to what I've been told, but most Pattern planes are about 1/4 to 1/3 deg wing pos relative to the stab, so gross error is in the order of 1deg (wing l/e down rel to stab).
Action as recommended above..............................
Bill.

Thanks Bill!

I missed your post #306 yesterday, but the advice is now well taken

By the way a buddy of mine bought an Angel last week as well from the same supplier and has found an indentical problem. Hopefully he'll chime in today as well.


I'm going to contact the seller and Fedon Aircraft today and see what they say. It still flies well, but it is a minor annoyance for a ship I have invested over a $1000 into.


Is there any chance the incidence differential is intentional?



Joe

Why not email to Sebart directly to get it from the horse's mouth? Might get you an accurate answer ...

Flew 4 packs worth today and then went to the hobby shop and bought an A50-16S. Gonna try 5s with the 15x8 prop on the A50-12L tomorrow and then the A50-16S on 5s with a 17x10 the next day. Gotta love those hobbbies


Also sent an enote to Fedon directly. I'll be sure to post when I get a reply.


Joe

Can someone check their Angel 50 wing tube with a caliper and post the diameter please. My tube broke and I need a new one. Fedon has not answered me you about a new factory one and I don't want to wait on them. I can get a cf tube from other places. Thx

Looks about 16mm OD with a wall thickness around 1 mm.

Got a response from Fedon:


So I'll check against the canopy line, and make some adjustments with the help of my buddy UAL767 then let everyone know how it goes.





In other news . . . I flew two new 5s5000TP batteries on the A50-12s with a 16x8 APCe. This was soooo much better than the 4s, because the 4s could only get to a CG of about 155mm and weighed in at a low wing load weight of 4.75 lbs. On 5s the CG was at 140mm and weighed 6lbs so she tracked much better even in slightly gusty conditions today. Below is a graph of the Hacker A50-12s with an APCe 16x8 on a TP 5s5000mAh battery:

Mine was more out than that.
I am suprised that you received a note saying .5 is fine. .5 degrees wing negative compared to the stab. Seems to go against most other pattern designs where the wing is positive up to .5 degree compared to the stab. I would be curious if anyone flying one that does not need any significant elevator trim can confirm that the wing is normally negative compared to the stab (leading edge down)
Thanks,
Stuart
