Nobler electric-First flights
« on: June 02, 2012, 11:57:04 AM »
Well my top hat is now in the ring. I flew my first electric flights on Friday the 1st of june. Everything went well wxcept for a few things that showed up that I didn't know about. I even charged a battery at the feild and it didn't take long. My system for this project was a eflight 15 moter with a RSM controller and two Thunder poer batteries. 3300 milh at 25C with timer set a 6.20 min. at 9000 rpm. My first flight was with an 11X5.5 prop which made it pretty slow so changed to 7 pitch for econd and got 4.9 lap times. What I liked most was the constant power in Manuovers.I also had very good line tension. I think I will now try the eflight 10 on my Arctic Fox as soon as I figure out what battery to use and I already have an ECS and timer for this system. I will then move on to bigger and better things but am now an electric freak with a passion for more. S?P S?P S?P HB~>

Andy,
How many amps did it pull on the 7 pitch?

Best,      DennisT

WAY TO GO LEO!   CLP**

I suggest you go back to the 11x5.5, program the timer to deliver about 9800 RPM and give it a go....

I think he's running three cells -- at least that was what he started with.

Hey Leo -- how many cells?

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

Sorry I have no way to test the amps I am using with the 7 pitch prop. The battery is a Thunder Power 3300 mAH 25C 3 cell lipo. All I am concerned about is getting thru the pattern and I did it by not using Andy's ECS. Doc ya gotta try it. It is like running a four stroke withoutall the fuss and mess. I dont have much paint on this because it is just a test bed. And I found out that Noblers don't fly too well when nose heavy so will have to do some trimming. At least I won't have to trim the motor much  and I will try Dennises suggestion of uping rpm and running the 5.5 prop. Thanks for that Dennis and tell your dad hi for me. Z@@ZZZ Z@@ZZZ HB~> HB~>

I wil do pictures as soon as I have time. Sytem runs really cool because everything is out in the open. I cut off the motor mount and made a breakaway motor mount and the control system set between the motor mounts in the plane with ruff opening for cooling of ESC and the battery sits above the ESC  and is held on by velcro and a velco strap. It doesn't look pretty but it works and will worry abot esthetics when I do Arctic Fox. UIsually test beds arn't pretty.so beleive this was a good choice. My Fox will have a eflite 10 in it and should have plenty of power. It will use RSM controller and 2200 mAH battery which should fit in it where the tank was. I will need to hog out the motor mounts so I can mount the motor in it. I think it balance almost where the balance point was before. I hoe this will yeild a very good electric stunter that is easy to haul around and flys well. I will do pictures as I make the changes. HB~> HB~> HB~>

Does your eFlight 15 have a k/v of 950, if so you should be using a 4 cell battery, not 3. (For proper governing.)  ;D

Or, if you are using four cells, check whether 3300mAh is more than you need -- a 3300mAh, 4-cell pack should be good for something like 58 ounces of plane.

Not that the extra capacity is bad -- just the extra battery weight that gives it to you.

This is a coincidence.  I have a UHP Gieseke Nobler Component Kit still in the box.  I have pondered making this an electric model ( my first) and leaving it in the raw clear covering to avoid doping, recovering and painting.   I will be following this thread with interest.

BTW, Dennis, if you or Big A have any words of wisdom about such a combo, feel free to enlighten a castor soaked veteran flier.  Thanks.

Yes, if you go to 4 cells, you should be able to use a 3000mah battery (or even less). Just keep the usage below 80%.  y1

Well, you don't need to make it fuel proof because of your own motive power, but at the Regionals a friend of mine mentioned that he was fueling up his plane, pulled the syringe off, then committed a dumb-thumb that resulted in a healthy squirt of fuel right into the center of some nice graphic on someone's electric ride.  He said he was in a (very short) quandary about whether he should reach over and wipe it off (and maybe take the finish off with it), or call the plane over and fess up (which he did).

So -- you still need to make the plane fuel proof, at least until we start having all electric meets.

Hi Dick
Go to the "List your set-ups" thread, Check-out reply #90, near the bottom of page 2.  Bob Branch posted his UHP Nobler conversion.  Bob did as you suggested, adding some vinyl trim stripes and graphics to the otherwise clear SLC covering.  Rick Sawicki had previously did his UHP Nobler in a similar fashion - both look cool.

They had to notch out the LE of the wing to get the battery pack far enough aft to achieve balance, I think the both did this AFTER assembly o it was kinda rough.  Modifying the wing before installation should save a lot of grief.

The next project for this package is my Arctic Fox. it's a tight fit but balances the same as engine and tank in the plane. This will make a small package that is easy to fly and fits smaller cars. I was wondering If I could get some package sizes for 15 size motors that can use 2500 MAH batteries?
