What is the current draw of the ignition unit on the DLE 30 and can I use a single LiFe battery to supply the engine ignition and my receiver. If so what would you reccomend as a minimum mah (my track number says I get my plane and engine tomorrow i'm so excited!!!)

Hi guys,

This is my first post on RCU!

Does anyone run their Edge 540 on electric power? What is your setup? How do you like it?

Ihave a lot of 6S 5100 mAh packs from my 90 size helis and would like to run 2 of them in the Edge 540 if possible.

Can someone tell me if the plane can accomodate 2 of those large packs?If yes, what motor/ESC combo do you recommend? I've seen the recommended combo in the manual, but I'm looking for other high-end alternatives. I'm looking to get really good power out of the system and can live with shorter flight times... Iwould like to get at least the same power as the DL30CCgas engines if not more... Is this achievable?

Any help/advice would be greatly appreciated.

Regards,
G

ps, I've talked to a good friend who flies lots of different aircrafts, and he suggested that Iget the Hacker A60 18Lwith a CC120 ICEHV (Ihave a NIPspare one). Would this be a good combo?He also suggested a 24 x 12 plastic prop. What do you think?

Overkill? That is a setup for a 33% plane. An A60 18L on a 12S setup is going to put out something like 30lb of thrust with a 24x12. This is a 10-11lb airplane.

Some quick, back of the napkin numbers here. This plane is designed around a 30cc power plant. Let's assume a 18x8" prop. At 8k rpm, you are going to get (theoretical) 18lb of thrust. Real world will be less. To get 8k rpm you need around 360 rpm/V if you use a 6S pack. Accounting for losses, 380-425 rpm/V might be a good target range. My electric stuff all uses Scorpion motors, but pick your favorite. Assuming your packs are rated at 20C or higher either the Scorpion S-4035-460 or Scorpion S-4035-380 might be reasonable starting points. At maximum amp rating, you should get around 1600-1800 watts from a 6S packs from those motors. At eleven pounds, that would be 171 W/lb. I'm sure someone will chime in and say you need to be over 200W/lb which is theoretically what a DLE30 would put out, but then I am not a hardcore 3D type person. A 1.5 power to weight ratio is plenty for me.

As with anything on the web, take the above with a grain of salt. It is likely I made a mistake somewhere along the way that makes the whole thing wrong.

Thank you for taking the time to respond.

The reason my friend suggested that setup is because of the fact that Ialready own lots of 6S 5100mAh 45Cpacks, and a NIPCCICE120HV.

I'll keep researching!

Thanks,
G

Nothing to stop you using the 6S packs, or the ICE 120HV, though it will be a bit overkill for a 6S pack. If you went with a Scorpion 5535-190 and 12S setup, you could use a 19x11 prop and get around 20+lb of thrust at a prop speed of 80+mph. That would work out to around 3600W. At almost 5 lbs of battery, motor, and ESC, I think you would be stressing the airframe beyond it's limits.

gorgin4325

So you're saying instead of the hacker motor and 24 x 12 prop, get the scorpion and 19x11 prop?Icertainly dont want to stress the airframe!

wpmcnamara

My Feedback: (9)

I would think that 3500W into a 19x11 is going to stress the airframe pretty good. Aeroworks does give recommendations for a 10S setup swinging a 20x10 prop. Their suggestions is for a Rimfire 1.60 motor. Based on it's specs, you are looking at around 9k RPM, probably less, limited by current capabilities of the motor. I am guessing they are speccing it out to match a 30cc engine, somewhere around 2350-2500W.

It all comes down to what equipment you have, and what you want to do with it (the plane).

gorgin4325

Thanks again.

What do you think about the setup that Iinitially mentioned in a 50CC Edge 540 or Extra 300? That is always a possibility! Would the system be sufficient in that plane?

wpmcnamara

My Feedback: (9)

I suspect it would make a fine power plant for one of the Aeroworks 50cc planes. Your thrust to weight would end up somewhere in the 1.5-to-1 range. At around 3800-4000W you would be on par with a DA-50 from a power perspective. You may want to look at prop sizes though. I don't know what kind of airspeed the 50cc's will need to actually fly well, right off hand. A 24x12 with 4kW put into it is going to get you around 5700rpm or ~64mph theoretical prop speed. Dropping down to a 23x12 loses you about 1.5lb of thrust, brings you up to about 6100rpm or about 69mph, for the same 4kW power budget. Trolling around Google, it looks like the Hacker A60 16L/18L is a pretty common motor for 50cc conversions, run on a 12S setup. Random reports put you in the 8 minute area for flight time for heavy 3D.

I don't normally deal in electric that big so you probably want to get at least one other opinion as I have just been running numbers based on theoreticals and quick Google searches.

Thanks again for your help, Iappreciate it.

7 flights yesterday and it flew great(with the exception of a dead stick once, but the gliding characteristics of it, was shocking) and the last flight, my batteries were draining, so hair raising/pucker factor scenerio). Extremely floaty or should I say, doesn't drop like a rock when the throttles cut. Quite the opposite, as it will and did countlessly float extreme distances, to the point of having to adjust my approaches, as she kept her speed and altitude so well.

On the deadstick, I think I might of course need to adjust my motor, as on the low end, I leaned it about 1/4 and after that, on the low, at points, I would give it throttle and nothing would be there, whereas, previously, not an issue whatsoever. It would be a little burbly sounding on the low, but, always there strongly and "bat out of hellish" type of performance on the 18*10, so this morning, I will back the low end out some to where it was previously. Maybe a little less.

I also, think I need to investigate another battery, as my flights, all of them weren't that long, and in total, I ran only two tanks(though, I have to admit, this thing burns up no gas whatsoever even moreso with my "slower" flying style. Hmmnnn, I think I will go and adjust it now, now that I am thinking about it all!

Im a bit confused....you say that the gliding characteristics are shocking but then you say its extremely floaty????

HelividD

My Feedback: (1)

Yes, both. Shocking, and both cool, because I did not expect the plane to be able to glide as far and as well as it does. It was weird because as much as I have flown it during the winter, it never exibited these characteristics. I was basically just blipping the throttle, after a high speed pass, it was coming across me from right to left, I turned towards me(left hand turn), it died about half way through the turn. I then tried to bleed speed, while keeping the nose down, and it gently(figuratively speaking for this model.. LOL) glided past me, I executed another left hand turn, maybe 200-300 feet to the right of me, and "then", it was ready to come down, and I landed it with a 3 pointer in the little rough..

Maybe I didn't explain it previously, but I figured anyone that had dead sticked a plane of this type, in my experience thus far, they don't glide like that(or anywhere near that far to be honest), and they are more like bricks falling out of the sky. But this thing, I mean, it was almost like a trainer, it was insane.. My flying buddies(guys with more plane experience than me), were like "wow, that thing landed great!".. I think that this is only the second dead stick landing I have ever had, so I'd have to say that it was more of the plane than me, because I was sort of shocked as it flew past me, how fast it was still going.. It was actually kind of comical...

But it was great! I know that I am going to re-richen my low end the 1/4 turn that I leaned it, because, though it burbled a little, I got no dead sticks, and the power was immediately there "always"..
