Finally. a shot of the tail wheel. I did not use the standard hardware in this instance, this is the first change I've made and not because the included hardware is cheap but because I don't like tail wheels that mount to the rudder. The included tailwheel is a metal rod that you bend and insert into the rudder before you glue the hinges. I've always steered away from those because you can't do maintenance on them without affecting the rudder and in my opinion, they put too much strees on the rudder with a hard landing. I've gone with a Sullivan tailwheel (12 lb size, I like the larger wire and higher stance) with a matching 1" tail wheel. I like the Sullivan because of the reverse bend, I find no matter how hard a landing, I never bend or distort the Sullivan gear...

Hey, good news about the aileron servos, too . . I'll still use a 1/8" ply packer under mine, just to be sure.

RE: Angel S EVO Build Thread
 

To secure the nuts holding the screws through the ballinks I use CA. But I apply CA to a needle and then let the needle touch the threads beside the nut. Never apply CA right from the bottle, it is to ask for trouble.
I replaced the pushrods for ailerons and elevator with 2mm and did NOT use the E/Z-connectors at the servohorn! You ask for slack, and I don`t trust if on anything else than small depron-toys... Instead I prefer a L-bend and use things like these to hold them: http://www3.towerhobbies.com/cgi-bin...?&I=LXAZC3&P=0 I would not use Z-bends either when I want slack-free connection, because when you Z-bend a pushrod you squeeze it enough to destroy the hole in the servohorn when you attach it.

Here's a shot of the Dimension Engineering VHVBec (Very High Voltage), I use these with all my electric planes, in larger ones I use 2 wired in parallel. These BEC's are the only ones I know of that can be wired this way without special circuitry to orevent damage (Ultimate BEC reuqires a seperate part to wire in parallel). Also a shot of the remote receiver for the Spektrum 6200 RX, mounted to the side of the fuse with velcro.

RE: Angel S EVO Build Thread
 

More shots of the Hacker A50 14L and Jeti Spin 75. The motor box was shortened by 10mm (it was quite easy after all) so the clearance is now eactly that same as if using the standard A50 16S that the model was built for. The ESC is simply mounted to the underside of the engine box with a wire tie, plenty of air flows over this area so there shouldn't be any issues with cooling.

RE: Angel S EVO Build Thread
 

The landing gear is a snap to mount, 3 screws in each. The wheel pants are great, they've even glued in the ply doubler for you and glassed over it, slightly different from the manual that shows you need to rough up the inside of the wheel pants and glue on the doubler yourself, it's now been done for you. The gear also has "lifting body" cutouts that get glued to the gear with thick CA, a nice touch and pretty!

Jack

RE: Angel S EVO Build Thread
 

OK, done! Here's the beauty shots with the graphics applied per the manual. They included some Hacker and FlightPower graphics in full color so I added a few as well, very slick looking graphics printed on heavy clear vinyl, nice touch. I plan on summarizing the build in a following message with any gotcha's and reminders for anyone interested. Calling this a build thread is somewhat of an exaggeration as most of the work is done for you. I didn't even have to re-shrink the covering before assembly, it was that well done.

Jack

RE: Angel S EVO Build Thread
 

Nice job Jack . . looks great. Can't wait to here what you think of the flying part :-)

Looks like it was a pretty quick build . . might make a start on mine next week. I'll post pics of my set-up on here as well :)

RE: Angel S EVO Build Thread
 

So overall I'd have to give this plane an A+, fit and finish is excellent, covering is top notch and all the small details that are done in advance just make it a dream to assemble. I calculated that it took me 7 hours of actual time, that includes me cutting the engine box and removing 10mm for the longer can Hacker motor. There was nothing difficult about the assembly, it goes together easily, the parts fit and nothing has to be cut, clipped, sanded or altered for a perfect finish. I replaced 3 items, the wheels (I like rubber, not foam), the tail wheel bracket (I don't like the rudder taking the weight of the plane so I used a Sullivan 12 lb.) and the tail wheel itself (again, rubber).

Tips;

1.) Don't forget the wing tube when unpacking, it's taped to the bottom box section. I almost threw it away!

2.) The Aileron servo cutouts are shallow enough that the servo bottom hits the ply layer on the top of the wing. My experience was that you can get them screwed down without bulging the top surface without packing out the
mounts.

3.) Use 6" extensions for the aileron servos, the standard leads hanging from the servos almost make it to the wing edge so only a little extra is all you need.

4.) If you use the included control rods and ball joints (I did, they are fine), make sure to use thread lock or CA (wicked with a pin or something similar) to make sure they don't come undone.

5.) When deciding on the motor, feel free to use a larger can and cut out a section from the motor box, it's quite simple to do (thank you Jeff, I wouldn't have tried without you suggesting it).

6.) When mounting the cowl, make sure you hold it UP rather than pressing it down against the top surface. You need a slight gap for sliding the canopy in at an angle before it drops into place (thank you jooNorway, wouldn't have thought of it first and I too would have had no room!).

7.) When mounting the "lift surfaces" to the landing gear, use gap filling or medium CA like they say in the manual. I thought at first this wouldn't last 10 seconds but it has proven very durable with drops every half inch and held in place for 30 seconds.

8.) When running the 24" elevator extension through the fuselage, cut out one of the small holes in the air dam at the bottom to route the wire by using an exacto knife and accessing it THROUGH THE BOTTOM AIR VENT HOLES in the fuselage. You can get in easily and if you instead run the extension up high, you risk getting in the way of the pull-pull cables not to mention having no extra room to get to the receiver comfortably.

9.) When running the pull-pull cables, cross them over themselves in an "x" pattern. This is not evident from the manual but if you look closely at the 2 possible wire paths, running them without crossing actually causes a bend where they pass through the fuse tubes. Likewise when you run the wire, only poke a pin hole through the covering where the tube is located rather than cut out the covering in an oval. The pinhole is all you need to push the wire through to run it and it looks tight!

10.) The APC 17" prop fits fine with 3/4" to 1" ground clearance at takeoff attitude. If you fly from grass go smaller but if you fly from something hard, a 17" is not a problem.

Flight info to follow as the maiden is this Saturday @ 7:30 AM!

This is interesting . . I am just putting the finishing touches on a Comp-ARF Impact, and then I am going to put the Angel 50E together . .

Looks like you did much the same, Jack ! ! :D

Hmm, I knew I liked you for a reason! ;-)

You'll love the Impact, sweet flying plane. You doing yours electric or glow?

*********************************
*** FLIGHT REPORT - ANGEL S EVO 50 ***
*********************************

I took it to the field this morning and got 7 flights on it, wow is all I can say! The plane tracks superbly, not a wiggle or flutter, it locks on a line and simply holds it, very nice. Takeoff was very gentle, I came up to half throttle and it just lifted slowly off the ground with just a hint of elevator. I've got the recomended throws for low and high rates, 30% expo dialed in and it feels and flies like my other pattern planes, the only exception is the aileron which is a little sensitive, perhaps a little more expo to work that out. landing is slightly hot, I don't mean fast but ever so slightly hot, it won't hang in the air (like my inspire 60) with its' thin wings and needs an slight heavy touch of elevator to flare at 6" above the runway. To be fair, my CG is 3/4" forward because of the heavier EVO 5000 packs I am using so this may play a factor but I think the wing profile is most of it.

The Angel looks awesome in the air, the colors are very elegant, not just a bunch of colors layered on top of one another, it looks very nice in the air. Contrast is good, the completely different pattern on the bottom is easy to distinguish and the dark tinted canopy easy to use as reference when going high, tumbling and trying to get a straight downline out. The canopy hatch held tight, with the force needed to pull it loose to change the battery, I doubt there is any chance it will come off in the air. I did notice a little rubbing off of the color where it slides under the cowl, I plan on adding a layer of 8 mil clear (3M clear used in auto detailing) to prevent more color rubbing off. This would actually be a great use for the left over decal material, there is a fair amount of clear left after you cut out the decals and the thickness is perfect to use to protect this area, I'll go back and edit the tips post for this one.

Motor temps never got above 100 F, the massive air flow is probably the most cooling of any of my models and evident in the low temperatures of the electrical components post flight. The ESC never got above 105 F and the batteries barely broke a sweat at 90 F, mostly due to this extra cooling. I do have to add the Hacker A50 14L setup I chose is not going to cut it, I think going overly safe at 44 amps swiging an APC 17 x 10 is evident in the overall slow uplines and hard pulling over high loops. Another look into MotoCalc and it looks like the Hacker A50 12L is what I should have chosen (not a big deal, I have one here for the next test) matched with a smaller APC 16 x 10 prop. The RPM/Volt on the 14L just isn't high enough to get the RPM's I need and if I tried to prop up to an 18 x 10 and get more thrust, I'd likely hit the ground not to mention that would only decrease overall speed, which I feel is too slow going into a tall upline.

Some background on the motor choice, I didn't mind the 16S they recommended but a bad experience with one recently made me worry about over amping. My battery arsenal is mostly comprised of 6S2P EVO 5000 packs, they can push current like nothing else I have and they will fry anything that can't hold up. I think running the recommended 16S with a 16 x 10 would be a viable option if you were using something in the recommended capacity (under 4000) but knowing I was going in with 5000's, I wanted to be safe. When I compared the long can motors, the 12L stood out as "the one" but when I went to order one for my Inspire 60 and the Angel, only 1 was available so I got a 14L as well. Bottom line, the 14L draws low current, has potential if I could prop up but in the end the 12L is what I need, I'm going to drop one in, drop down the an APC 16 x 10 (though there was no issue with the 17 and clearance, if I don't drop down I'm looking at close to 60 amps again, a little too hot if you have a long, demanding flight in the wind) and fly again Wednesday.

Here is a MotoCalc comparison (the important part, the bottom half of the comparison page) showing the difference between the 2 setups. The one on the left is the current Hacker A50 14L with an APC 17 x 10, on the right is the Hacker A50 12L with an APC 16 x 10. The amp draw is fine for both (knowing I have more-than-adequate cooling, I am not as concerned about amps), the efficiency is plenty on both setups but the watts per pound and thrust on the 12L setup is really nice for the amp draw. I'll be moving closer to 150 watts/pound and the vertical gets another 1,000 FPM, these numbers match my Inspire 60 which has unlimted vertical and can pull out on slow uplines, I think I'll be happier with this setup. Bottom line the Angel holds so true on it's line I doubt I'll fly my Inspire 60 that much anymore. Adding more power is the only thing lacking on this setup and I'll get that fixed, anyone looking at one of these as a possible pattern practice plane or just for fun can't go wrong!

Jack

RE: Angel S EVO Build Thread
 

Sounds, great Jack . . I have only flown a glow version with OS55AX, and it was awesome. Very strong vertical . . . . almost over powered at 2.4kg (5 1/4lb).

How many Watts static is the current set-up ? I am expecting my set-up will be propped to a about 1000W. This system flew my 3kg (6.6lb) Katana Freestyle vertical without issue.

I will be using 3700mAh 5S1P . . at 430gms/pack it should be a "little lighter on the wing".

I want to use it as a pattern practice plane. The '09 schedules are shorter now, so it should be no problem.

The Impact ?? 140RX glow . .

I have an Integral (in the box) as well . . and I am not sure how to power it. Was thinking about YS170 but it is very narrow in the nose. Electric?? have been thinking about that too ;).

JB

RE: Angel S EVO Build Thread
 

Geez, mine weighs in @ 6.6 lbs so yeah, I imagine a 1 1/2 lb lighter plane would be ballistic. I have a few electrics with unlimited vertical, I expect once I make the change to the motor, this one will be as well.

I measure 942 watts in with the Whatt Meter, 44.8 amps, a little light for a 6S setup but I really wanted to try one well within limits for once. I always end up with 1,250 to 1,400 drawing 65+ amps when I don't plan it out, hot but a little too demanding on some of the components.

Well, like I said it will fly but I think you'll want 6S. MotoCalc shows that setup (5S 3700, assuming Hacker A50 16S motor and APC 17 x 10 prop) pulling 803 watts and only 144 ounces of thrust (121 watts/lb), pretty much what I'm seeing now with my current setup which feels heavy.

I don't know if you saw my build thread but I ended up going electric. Axi 5330/F3A, 12S EVO 5000, Jeti Spin 99 and Mejzlik 20 x 12. I ended up propping down to an APC 18 x 10 since the Mejzlik was drawing 84 amps (I wish they made an 18" or 19" carbon prop) and with that setup it's a much lighter 65 amps, still unlimited vertical.

So your a collector like me, seems like I can't turn down a pretty plane. I've been looking at the Oxai Beryll EP and Zeque EP but the prices are insane. So I started comparing the Integral to the Shinden, it seems they are both pretty nice but the Integral needs a fair amount of work compared to the Shinden. Either way I'm going to go all white this time and get a custom paint job on my next pattern ship (of course all electric!)...

Jack

RE: Angel S EVO Build Thread
 

The Integral is DEFINITELY not the same build/kit as the Impact. The Integral is a true ARF with very little to do. Just fit the firewall, or electric mounts (which come with it in Carbon Fibre) and fit the horns and radio gear and it's pretty much done.

The wing/stab tubes are fitted and anti rotation pins are aligned and fitted. A pretty quick one really.

The fuse is a laminatede glass/balsa sandwich. Very stiff and VERY light. Pretty good value considering that two of these were in the finals of the world champs (the 3rd one was a ZN Line version with one piece foam wing flown by the designer, Stephane Carrier. His version is a fair bit different).

JB

RE: Angel S EVO Build Thread
 

I think you have described the Angel perfect Jack ;) I am so happy we can buy decent ARF pattern-trainers. Most of the stuff "out there" is 3D-stuff [:'(]

Btw; I liked this Sebart-gadget too much I think. Yesterday I bought a Katana 30S from Sebart. Just to have a plane to do hovering and playing with to avoid stretching the limits with the Angel. The Katana will be a cheapie, using stuff from UH.

RE: Angel S EVO Build Thread
 

I had a chance to fly the Angel with the Hacker A50 12L (over the 14L I purchased which I feel doen't provide enough RPM's) and it flys great! I got 8 flights on it last Wednesday and the additional RPM's really make the difference. I guess in the end if you use the recommended packs (3700's), then stick with the A50 16S but if you have larger capacity (i.e. more amperage) packs, go with the 12L...

Jack

RE: Angel S EVO Build Thread
 

Hey Jack,

Actually, there have been several now that were designed from the ground up to be electric first and then converted to IC if desired. SebArt's Katana 50 a little over year ago was one of the first such. You actually had to buy a kit to convert it to IC. Since that time there have been several other manufacturers that have gone this route in the 55" to 85" WS range.

SebArt was one of the first though!!

Great thread BTW!! The pictures are nice to see. I like the airfoiled tail surfaces too.

BK

RE: Angel S EVO Build Thread
 

Joo, you'll like the Katana 30. I did a review on it on another RC website, including a build thread that I still update and post in on a regular basis. It's a great plane for it's size and weight. I've put probably 200+ flights on mine.

BK

RE: Angel S EVO Build Thread
 

Bill,

Thanks for the nice words on the build thread, seems not really fair to even call it that given the amount of work done for you in advance. I never knew about SebArt until the Angel came out but I hope this is a sign of what all manufacturers start doing for us e-fliers...

Jack

RE: Angel S EVO Build Thread
 

Jack, I could not agree more, I hope that more and more follow the lead of companies like SebArt!!

BK

RE: Angel S EVO Build Thread
 

I think there will be many more quality products coming from SEBART in the near future.

I am already a fanatic of the Sebart product. Seba is an excellent designer and pilot, so the combination of his designs and his manufacturing company will see me fly many more of his planes in the coming years.

What about his NEW Sukhoi ???? . . . 194cm Span and Length (76" ) . . VERY NICE [sm=thumbs_up.gif]

Ohhh, hadn't seen that one yet. I'm liking that a lot!! Love the colors too. Hmmmm

RE: Angel S EVO Build Thread
 

is there a version that are for glow or is there easy to modify to glow ?
could not find it as glow!
