What power system will you run in your Angel 50??

RE: Angel S EVO Build Thread
 

I think that Luigi is sending me a motor that is comparable to the Hacker in KV and weight. It's an off brand motor that he's going to be carrying. I've also got the recommended Hacker that I'll likely play with as well. :)

Hi Joe,

Did you had a chance to fly this set up yet? I am looking at the same motor/ESC combo to go with 5S on this plane, and your input would be a great help in the final decision.

TIA,
Kevin

RE: Angel S EVO Build Thread
 

Plane is not done. Tied up for a while. It's winter of course.<g> My gut feeling based on my E-F Extra 300 is that it will pull just fine. I just quickly thru a bunch of stuff on the scale and it all added up to about 6lbs. THe E-F 300 was all up 6 lbs 5 ozs on a Duralite F3A 5350ma 5S pack. Plus Angel S is aerodynamically cleaner. Same Torque motor from E-F 300. It bolts right in place and has to be offset by about 5/8". The Torque specs out right around the same as our friend from Norways' Actro I believe. On the E-F 300 on a 15X8 APC it was turning around 7700 rpm, 60ish Amps, and around 1000 W plus. These readings were at temps in the 40's.

RE: Angel S EVO Build Thread
 

Thank you for the input, Joe. I am looking at this plane as a practice plane during lunch time, since the field near the office is a little small, it doesn't quite fit the 2M, but Angel S fits just fine. Since I have the charger and balancer up to 5 cell already, and the possibility to use the batteries in the 2M later, using the 5S packs seem logical. The only concern I had was the prop choice, but if 15x8 APCE is pulling 60ish amps to get 1KW, it seem to have some room to try out few different props.

jffter. I have several evo25 5000 batteries I use in my Trex600 heli and would like to build an areobatic plane that would take these batteries. I don't care for 3D stuf but was a little concerened with your comment about a slightly hot landing. I am looking at the inspire60 and possibly extra300 free style and would like your opinion on these planes and possibly other choices. I would like a plane that slows down with a flare for loanding. Thank you in advance.

Bob,

I wouldn't be the slightest concerned over that comment, it was more me not being used to the Angel combined with having flown the previous 100 flights on my Inspire 60 with a fat wing that slows down to walking pace. The Angel comes in nice and slow if you like that, you can get it down to a comfortable speed but certainly not as slow as the Inspire 60, the wing is just too slim. Both are excellent flying planes but I give the Inspire an edge in stability, both are excellent in calm conditions but the Angel looks just a tad skittish in a breeze compared to the Inspire 60.

Both planes are perfect candidates for 6S 5000 packs but I'll give you this guidance. If you use the 5000 bricks (each cell is 5000 mAh so you have a fat 6 pack) then you will be happier with the Angel as the pack fits perfectly in the plane as do the longer 6S2P "long" packs that use 2500 mAh cells, so you can use either. The inspire 60 has a lot of room over the wing tube to mount a tray so the battery can slide fore and aft for balance but only a long pack, not a brick. You can use a brick but you'll have to get the balance right and make a pocket for it, my experience says it wants to be over the wing tube so you'll have a harder time with a decent location for a brick-type battery.

My power setup on both is identical, Hacker A50 12L, 17 x 10 APC e-prop, Jeti 75 Spin controller and they both have unlimited vertical, pulling a max of 68.5 Amps and an average of 45 over the entire flight. The Spin controller shows 7,520 RPM's and the performance edge goes to the Angel simply because of the weight savings it has over the inspire. Quality goes to the Angel simply because the Inspire has crap covering that needs to be shrunk out of the box. unfortunately this also warps the HUGE surfaces (cheaper wood it looks like to me) so you'll have to take you time and warp them back. Inspire also suffers from weak laminated gear that will delaminate over time no matter how light you land the plane. It just flies so darned well that you will get over these issues but I'd recommend both, they are all I fly anymore...

RE: Angel S EVO Build Thread
 

Hi Jack. Thank you for the reply. Thgis is very good information from someone with experiance with these types of planes. I have sent you an email to ask you for your phone number for further discussions.
Bob.

RE: Angel S EVO Build Thread
 

Sure, I will gladly answer any questions I can...

Jack

<NOT ANGEL RELATED - SKIP>

Bob,

I took 2 pictures of the Inspire 60 with both the EVO long and brick packs in, turns out the brick pack has just enough room to fit over the wing tube on its side. Both of the pictures are shown with the packs in the right position for correct CG...

Jack

RE: Angel S EVO Build Thread
 

Anyone can advise what is the spinner size? Starting to put together a list of parts needed for this plane, and I hope 5S is going to work.

TIA,
Kevin

RE: Angel S EVO Build Thread
 

Kevin,

It comes with a white spinner in the box, I was tempted to go CF but the supplied white one really completes the look. As for 5S, as long as you spec the motor out you should have no issues, I'd recommend you switch to the A50 12S over the A50 16S if you are going to go 5S, it is rated the same except for the 500 rpm/V instead of 380 rpm/V, the extra rpm's will offset the loss you'll have dropping from 6S to 5S...

Jack

RE: Angel S EVO Build Thread
 

Hi Jack,

Thank you for the information. I will hold off on the spinner purchase since there is one in the box already.

My current plan is to go with the Extreme Flight motor, it has a 570 kv rating, and by running a 15x7 or 15x8 APCE with 5S battery around 4 to 5KmA, should be able to deliver 1+KW, which I hope is enough to fly this plane through advanced schedule. But I am new at electric, for sure not familiar with Hacker A50 12S, eventually I will consider getting a software like MotoCalc to help me figure out different setup, but for now, the EF motor/ESC is the main candidate. Any comments or suggestions?

Kevin

RE: Angel S EVO Build Thread
 

Kevin,

I think you're on the right track with that motor, I don't know enough about the physical size so I can't say it's a direct bolt-on replacement but the kv rating is what I'd want for 5S. I think you might want a more agressive prop (pitch) but you can always do that later, I am flying with a 17 x 10 APC currently but don't suggest you go that big, perhaps just more pitch on your 15 (forget what you know about glow, it doesn't really equate to electric as far as prop selection goes)...

Jack

RE: Angel S EVO Build Thread
 

Jack,

I think the 15 inch by something prop should be the right starting point in my case, but the only thing I am not certain is the difference in P-factor between the 15 inch vs 17 inch like yours. Did you had to add more right thrust on your setup? One more question, could you comment on the incidence on the stab and the wing, I mean did you had to do any adjustment?

Kevin

RE: Angel S EVO Build Thread
 

No, I didn't modify the thrust angle nor the incidence, the plane flies perfectly out of the box and your setup isn't different enough to change that. Do me a favor and post your power setup (batteries, brand, C rating, motor, impedance, rpm/V, resistance, etc) and I'll run it through MotoCalc and post a side-by-side of mine to give you an idea of performance...

Jack

RE: Angel S EVO Build Thread
 

Jack,

The batteries are:

ThunderPower High Performance series
4450 mA
22C Continuous
40C Max

or

MaxAmps
4000 mA
20C Continuous
30C Sustained
50C Max

Motor:
Extreme Flight 4014T-570
Resistance (Ri) 17.5m Ohm
Continuous current: 45A
Maximum current: 80A (20sec)
Maximum efficiency: 85%

These are all the parameters I can find, hope is enough to run MotoCalc.

RE: Angel S EVO Build Thread
 

Good thread read..thanks for all the info's.

I have recently finished and flown the Angel 50E , with the 'standard setup' on 3850 6S Thunder Power / APC 16x8.
Off the board, flew very well, now just a bit more 'trimming' to do.


Good flying
Tony

RE: Angel S EVO Build Thread
 

Kevin,

The most important data out of everything is the internal resistance of the LiPo's, that really determines if you've got a dog versus a hot setup. I've looked up the other TP's and some other newer packs and made a guess based on that data and here are the results. Pretty good if you ask me, you're going to get almost the same performance I get with 6S packs (you'll be pushing more amps though) with only 5S, not bad! I'll be curious what you think once you fly it, from what I see, the numbers look great...

(Make sure you use the "expand to actual size" button to read the results)

Jack

RE: Angel S EVO Build Thread
 

Jack,

Thank you for running the simulation, which confirms the information I have gathered to this point, and more. Your data really adds significant level of confidence to this project.

I have ordered the plane yesterday, which should be arriving sometime next week along with other components; hopefully I can report back on the performance in couple weeks. Meanwhile, I am going to work hard to keep it light and see if I can hit that 89oz AUW as showing in your data, which I think is doable.

Kevin

RE: Angel S EVO Build Thread
 

Given the precise reliable setup required for this type of model I wonder if you guys here went with the standard pushrods and connectors that are supplied with these kits:



http://www.srcmc.co.uk/images/Extern...Connector2.jpg





http://www.srcmc.co.uk/images/Extern...Connector3.jpg




I know a lot of people do not like the integrity of this type of pushrod connector, particularly the fear of things coming loose, however, they do seem to be the designers choice in the majority of these tpye of kits. - Sebart, Fliton etc.

Do you have any recommendations for a successful installation -



http://www.srcmc.co.uk/images/Extern...Connector4.jpg



- Should the locking nut underneath be done up tight, or will this prevent the connector from turning in the servo horn which I think it needs to do?

- Is it advisable to use a dab of thread lock on the lock nut and or the grub screw?

- Anything else to watch out for?

- Would you replace them?


Thanks,

Russ

RE: Angel S EVO Build Thread
 

Absolutely not. Linkages are POS and have slop. I used NMP ball links from Central Hobbies and Hangar 9 4-40 Titanium turnbuckles. No slop whatsever.

RE: Angel S EVO Build Thread
 

Russ,

I used the stock hardware and it works perfectly. Forget about what kind of connection they use and ask yourself when installed, is there any play? The answer is no, they are solid, firm and perfectly sized for this plane. I didn't tighten the lock nut so tight that it wouldn't swivel (though a little firm), what I did was use a drop of CA to make sure it doesn't back off. I did replace the tail wheel because I don't like the weight of the plane on the rudder (I switched to a Sullivan) but other than that, all stock with 25+ flights on and no issues...

Jack

RE: Angel S EVO Build Thread
 

Thanks Jack. You have confirmed pretty much what I was thinking - if installed correctly they should be fine. They are perfectly sized and weighted for this plane and so I think I'll persevere with them.

Russ

RE: Angel S EVO Build Thread
 

Hi Jack. I just got back from a trip and I now see your reply about fitting the EVO25 brick in the Inspire60. Thank you for your efforts to verify that the EVO25 brick will work in the Inspire60. I have one comming this week. Later. Bob.
