RE: Angel S EVO Build Thread
ORIGINAL: quist ORIGINAL: Dave Kelly Hi All, Strange thing i notice despite Knife edge being almost perfect and the c of g at (or very near where its supposed to be ..145mm or on the fuselage cross brace).. i need to hold a little down elevator in inverted flight..Does anyone else have this? best wishes Dave It is good to see that everyone with this plane is having a good experience. I wish they could make an inexpensive 2m plane with all would construction. Mike |
RE: Angel S EVO Build Thread
I don't remember saying I have an incedence problem other then the twist at the wing tips which I twisted back.

Quist
Relax, you did not say you had an incidence problem, all I was trying to point out is, that if you are confident you have the right C of G the need for up elevator trim can be either the thrust line or an incidence problem. Mike |

ORIGINAL: Dave Kelly <edited> I need to hold a little down elevator in inverted flight. Does anyone else have this? best wishes Dave Yes is the short answer, every plane I have needs negative push to hold level while inverted, including my C-ARF 2M pattern plane. interestingly enough someone told me this was wrong, they said a good plane trimmed out properly will go inverted without any push. Quite frankly I never knew if that was right or wrong, seemed a fair enough argument to make but nothing I've flown will do that. While at SEFF this year I had the chance to talk to QuiQue Somenzini, I asked him if this was true and he said absolutely not, He said sure, you can likely trim a plane out so that it flies the same right-side up as well as inverted but you'll end up with a poor flying (and tracking) plane. he said every plane needs a little push when inverted to hold its line and you should spend the time trimming the plane to track properly...

RE: Angel S EVO Build Thread
ORIGINAL: BaldEagel On the FlightPower packs, why is it when you buy four packs all the same the cables come out in different places, some on the same side some on different sides, some with both wires at the bottom of the pack and others with them one top one bottom, it would be nice if they where consistant then you could shorten them to suit your installation and tidy everything up. Mike I've been annoyed by this lately as well, they NEVER did this in the past, the wires always came out the same on every pack, one out each side. Lately I've gotten some packs with both out the side opposite the balance tap and other packs with the wires coming out opposite sides. I've decided every time I order I specify in the notes section which I prefer (I actually prefer the tap on one side and the lead wires together on the other side). I don't know if Flightpower has a second assembly plant or may be changing over to the other way and we're seeing the results of the change over but this back-and-forth is annoying (especially given their quality, seems odd that they would be inconsistent)...

Jack I had another two flights today (thats 3 and 4 on the ship) the wing tip balance has made vertical manouveres better but i still get a slight pull in uplines to the left...(requires a smidge of right rudder) only 2500mah pulled from both EVOLITE 4270 V2 packs in 8.5 minutes.... Does anyone else get a resonating buzz when they apply rudder in knife edge flight? brgds Dave p.s A smidge is a very small quantity (of anything) in Scotland!!!! |
RE: Angel S EVO Build Thread
Mike, Jack, I have many flightpower packs and all have the positive lead and balance taps exiting one side and the negative the other. I have never liked this but, at least it was consistent. Oh, I just checked my two newest packs. all leads exit the same side on these new packs, hmm.
I got five flights on my Angel yesterday, mine also pulls a little to the left on uplines and requires a smidge of push inverted. Love the plane! Dave. |

Does anyone else get a resonating buzz when they apply rudder in knife edge flight? brgds Dave p.s A smidge is a very small quantity (of anything) in Scotland!!!! No "buzz" in KE on mine. Check that you don't have something loose (cowl, trim, covering, canopy, etc.) that may be effected by airflow in the KE position. The lateral balance actually has minimal effect in up and down lines. This is surface trim (incidences, etc.) and thrust angles. For lateral balance, first check it on the ground, then pull tight inside and outside loops (in the air :eek:). Check for a dropping of a wing, check which wing it is and if it's alway the same wing . . add a little tip weight to the opposite wing (or remove it if you had added too much on the ground). PS. this has to be done on calm conditions or at least fly the loops directly into the wind (calm is always better for this stuff). Mine was pretty good, and didn't need any tip weight. The thrust angle could do with a slight change, but at the moment I have just mixed it out. Cheers, JB |
RE: Angel S EVO Build Thread
Jeff, could you tell me how you check lateral balance on the ground? Do you suspend the plane buy the prop shaft and tail wheel?
Thanks Dave |
RE: Angel S EVO Build Thread
My RC instructor always taught me to trim the rudder when pulling straight up away from you, in essence you would remove any pull to one side during proper rudder trim. The idea being when going straight up, the only effect gravity has on the plane is pulling directly down, not affecting the trim, making it "true". So I have to ask, if you notice pull in any direction going upline, isn't this an indication the rudder isn't trimmed properly? I can't see how the pull to the left wouldn't be seen flying straight and level as well...
Jack |
RE: Angel S EVO Build Thread
Jack, the pull to the left is very slight. And no, I do not notice it in straight level flight. I use right rudder to correct this slight pull to the left. Right rudder also keeps large loops on track. I will try more right rudder trim today.

RE: Angel S EVO Build Thread
ORIGINAL: 172amd Jeff, could you tell me how you check lateral balance on the ground? Do you suspend the plane buy the prop shaft and tail wheel? Thanks Dave I have found this method to be very close, with possibly only minor adjustment after the "inside/outside loop" test. Cheers, JB PS. The rudder trim I test by flying away from you directly into the wind (no wind is always better) in a 45 degree upline. Trim the rudder until it flies up straight, then roll to inverted half way up and see what it does. If it veers to the left or right, adjust the rudder trim again until it flies straight while inverted in the 45deg upline, then recheck the upright. If you end up with a compromise where it will veer slightly one way upright and the other way inverted (which is actually still the same way), the model is llikely to need a thrust line adjustment. |

RE: Angel S EVO Build Thread
thinking of using a scorpion 4020-12 outrunner on 5S (5250 mah F3A pack).
http://www.flyelectric.com/Scorpion4020-12.html would this motor be sufficient? |
RE: Angel S EVO Build Thread
mikedsilva, I am using a scorpion 4025-12 in my angel. I am running it on TPX 5000 6s v2 packs and a apc 16-12 prop. This gives me all the power I want. I did a couple flights yesterday with my wattmeter on board the angel, peak amps of 65 and peak watts 1400. If I had a 5s pack I would run a test for you.
Dave. |
RE: Angel S EVO Build Thread
oops, er disregard my last post. Mines a 4025-12. Sorry!
Dave. |
RE: Angel S EVO Build Thread
Should work. I'm using a 570 Kva motor(Torque 4014-T570) on the same packs with a 15X8 prop.
61 flights to date<g> |
RE: Angel S EVO Build Thread
I am using a Hacker A50 12S with a 15-8 prop and it works very well on 5S packs. I think it is 570kv also.

RE: Angel S EVO Build Thread
I use a 17" APC prop cut down to 16" - stops the very thin/flexible prop tips of the 16" APC prop 'buzzing' in certain manoeuvres.

RE: Angel S EVO Build Thread
Hi
I was out with my Angel today and on the second flight I smacked a particularly strudy thistle on landing which knock one of the lift thingies fairings off one the undercarriage legs. I was having such a good time that i decided to fly again accepting that i would probably need a click or so of aileron to compensate. Plane took off and needed zero aileron trim. So my question is do these things actually do anything or are they purely asthetic? David I also get a resonating buzz in Knife edge. Mike |

RE: Angel S EVO Build Thread
Any opinions on how an E-flite 60 would work on the Angel? I've ordered the airplane and am considering various power options. I'm new to electric, so I need all the help I can get, but it looks to me as if the E-flite would be a good match. What do you guy's think? RS

RE: Angel S EVO Build Thread
Jack,
Thanks for taking the time to run the numbers on it for me. Sounds like the E-flite might not be such a good choice after all, when compared to your A50-12L. I'm just curious about how it (the E-flite) would measure up to the recommended A-50-16S? Thanks for your help....RS |
