I have a NIB Score arf that I was going to sell but now have been tossing around the idea of converting to electric seeing as it has a firewall mount .

I have messed around with a few of the calc programs and looked through the setup thread and have a few ideas of what to use for a power system but thought I would ask here for suggestions from those with more experience converting CL arfs to electric.

here are the Score specs

Wingspan: 56.5 in (1435 mm)
Wing Area: 677 in² (43.7 dm²)
Weight: 60-70 oz (1700-1985 g)
Wing Loading: 12.8-14.8 oz/ft² (39-45 g/dm²)

it depends on what quality gear you want to add to it.... if you want to go one of the cheaper ways - then I would recommend

Motor -Turnigy 35-48-900
Battery - Zippy Flightmax 4s 1p 4000MaH (20c)

ESC and Timer are pretty standard .....
ESC Phoenix ICE lite 50 or Phoenix 45
Will Hubin FM9V timer
APC 12x6 Pusher or 13x4.5 Pusher

Hi Bud,

Wynn's suggestion will work well for sport flying, and is inexpensive, but you may want to spend a few more bucks if your a competitive flyer and want to do the full pattern cleanly.

I have an ECL Score. They have a thick (high induced drag) airfoil and they end up over 70 oz. RTF. It is a very good plane, but it requires a lot of power to fly well. Eric Rodgers flew one in Advanced, he used a Pletenberg motor with a 5S 18.5V battery. I use a Pletenberg 25-14 with a Hyperion 5S 4200 mAh battery, Hubin FM9 Timer with his programmer, Phoenix ICE 70 (I think the 50 would have been enough?), 13 x 7 prop.

You will be happy with this plane, it flys very well. There is plenty of room for all the E stuff. And your right, the FW makes motor mounting easy. It is also easy to make a complete take-apart.

Please take a few min. and read some of the Score threads, they will point out the few changes needed. These are not hard and only take a few hours to complete. (order new 4" BC/LOs and CF pushrods, ball links, from CLC, ..... reinforce LG mounting in wing, or move LG to fuse.)

There are alternatives between these two extremes. Check on the "Setup" thread at the very top of this section. Just make sure you compare setups on modern thick winged, heavy, large planes.

Remember: You can NEVER have too much power! Just ask our current world champ Dave Fitz., or Paul. ;-) ..... Dave's plane is smaller and lighter than your Score and he uses a PA .75 on a Pipe! One of Paul's planes is the Score size, (but of course it is lighter) after watching him fly and talking with him, I copied his (Kim's) E setup for my Score and my P-47.

Regards,

Yeah heh, I was going to sell the Score just due to the fact of all the mods they need. I had purchased a .60 glow engine for it. I will most likely get an AXI motor for it and run some 45C Hyperion packs yet to be determined with a castle Ice Lite 75.

I have decided to shelve the Score Arf for now and have purchased a quick building kit designed for electric.

Funny you should bring up the Score. I have a wet version and just flew it this past weekend for the first time in a year. The Score is one heavy plane and the wing does have lots of drag. The rule on the score wet or dry, you need lots of power! I started with a ST 51 and now fly it with a LA 65. The 51 was marginal, the 65 flies with authority. I would keep that in mind when selecting a electric system for your Score. Oh and by the way it also wants to dislocate my shoulder on every flight.

Yeah I had a couple of guys who fly electrics in contests tell me to stay away from the Score Arf for now, that I would be much happier if I built a plane designed for electric for my first E-control line stunt plane.

Bud,

Great to hear you would like to give ECL a try.

There are many great angles to take with an aircraft this size and all that I have seen posted here will go very well for you.

I would however suggest a different angle. I am a big fan of Turnigy SK motors. They have really worked well for me as for many others in this forum. I would suggest the following:

Turnigy SK 42-50-650Kv
Turnigy/Zippy 20C 6S (22.2v) 2200-2650's
Phoenix ICE 50 Lite ESC
Will Hublin FM-2 Timer
APC Electric Thin 13 x 4.5P Prop
64-66' 0.018" lines

This is a very solid set-up. Set RPM for 9,800-10,200 and that should yield a 5.1-5.35 sec/lap. This will provide a big power feel and be very reliable as well. You should use about 1600-1800 Mah/flight depending on final weight and desired lap time.

Note: This is my set-up for my new (675 sq in) CLPA model. I planned on competing @ the NATS this year, but life just got in the way. A few less baseball tournaments and family commitments, maybe I can compete next year.

Good luck with whatever you decide. The Score needs a bunch of power to fly. This system will fly it like it isn't even there.

Take Care,

I completely agree with Archie's numbers for the Score. My LA .65 powered Score flies with a 13 x 4.5 IC prop and I launch around 9500 RPM and currently getting 4.7 second lap times. I am slowly bring down the revs to get to 5.0 lap times. I know at 9000 RPM with the 13 x 4.5 I cannot do the pattern so somewhere withing the 500 RPM range lives the sweet spot. By the way, the reason I had not taken it out for over a year was the size of the Score. It won't fit in Larry Renger's car. I am about to replace my 87 Ranger with a new truck.

Hi Andy,

Did you make your Score with the wing detachable like it was designed? Or did you glue it to the fuse in the traditional CL way, making it a really big traveling companion?

The reason I ask is that I think E power and take-apart go together like Las Vegas and Fun. Because we can now fly quietly at our local parks while carrying very little support equip. it makes sense to have the plane be easy to carry in our smaller cars, bicycles (with trailer), walk (god forbid, NOT in CA! Actually I think it is illegal to walk in our state! ;-), etc. Smaller cars, like it or not, are in our future. I think E power and take-apart fit neatly into this future.

I'll never forget seeing Howard packing his Prius after a contest. I admired his great act of patriotism in getting such a fuel efficient car to help our balance of payments and helping us get out of the M.E.. He was on a 2 week vacation trip in the car with his lovely wife with all their suitcases, etc. Then he was putting in all the wet support equip. and then this HUGE PLUS SIGN of a CLPA plane was somehow squeezed in. Yes he got it in, but it would have been sooooo much easier if the wing came off (on purpose ;-), and if it was E powered, even better.

If you ever want to fly the Score on E power, Archie's suggested system is relatively inexpensive and will work well for you. But, if you glued in the wing, it may be too late to saw it in half! ;-)

Hi Rudy
Yep I built it as a one piece airplane. But I have solved my transportation problem, this morning I took ownership of a brand new 2010 Ford Ranger. I have have what I need to haul my toys around. Larry will be happy, he has born the majority of the transportation duties for the past year. I agree with you about take apart and electric, they do seem to go together.

Keep in touch buddy, and keep flying.

Andy

Well I came across a Phoenix 60 esc at a good price and purchased it.
Now all I need to do is hunt down a motor.
So as soon as I get a Sailplane off the bench I am almost finsihed with I am going to drag out the score again.

TDM · « **Reply #12 on:** October 06, 2010, 07:06:12 AM »

???So you get a 400$ plane and then a $$$$$$$$ truck to carry it total final price for the plane OMG your wife must be going

by now. Who is the MAN

What kit is that, I didnt know there were any kits available that are designed specifically for electric ?
