Glen spickler Quickie 500 convert to Electric

Hello all, I have a Old Glen Spickler Quickie 500 It had a Webra 40 engine with tune pipe with a 9x8 APC prop... It was good for around 110-120 MPH. I do not expect to go that fast Electric cause i do not have $500 on a power system.
I just want something that will still fly well and faster is better. would like 80 at least.

anyone have any suggestions? I know there a lot of cheaper motors, turnigys and stuff out there but not sure how to pick on.

I would like to use 3 cell 2200mah battery's, because I have a few of them, but if I ended up having to go 4 cell it be okay also . or maybe two 3 cells together

I looked today and there is plenty of room in the fuel tank area not sure how the balance will work if i have to cut out some to put the battery's back more over the wing I guess I can.

the plane was 3 pounds with the glow engine mount servo and all. I lost about 1.5 pounds taken all that off it, Not included the wing weight.

Thinking between a 50-70 amp esc
I have heard good things about the ZTE seris maybe I will go with this one
http://www.quantumhobby.com/ZTW-A-Se...ztw85asbec.htm

Just need help figuring out a motor. I think it could swing a 10x6 maybe a 11x6 prop w/o being much of a issue, if i needed to put bigger wheels on it I guess i could.
any ideas?

Similar overall size to EF-1, although they have a fair bit less wing area at max 375 sq in.

If you run it on 4S, with about 3000 mAH and a motor weighing close to 200g with Kv around 1200-1300, and a 9 x6 or 8 x 8 prop, you'll get seriously fun performance

A cheap option is the Hobby King motor approved for EF-1: http://www.hobbyking.com/hobbyking/s...00KV_930W.html

The 85A ESC would be fine

On 3S 2200 for decent sport performance only but no real speed, Kv nearer 1000-1100 and a 10 x 8 if it will fit , eg http://www.hobbyking.com/hobbyking/s...ner_Motor.html

Thanks for the info.. looking at all that my weight would be close to what it was glow, i like to keep it a lil lighter, but that motor is really good? I see it run on 3 cell but watts are way down.
Guess I am not sure what a EF-1 is. okay just looked it up, it looks like it has a tiny thin wing
this thing from the specs i found online says its a 50 in wing span and 500 sq in wing area.
3-4 pounds is ideal flying weight. i didn't weigh my wing guess i should seems it i pretty light

I just checked props and a 9 inch is best but a 10 would also work, a 11 would work maybe but be pushing it, it be cutting the grass if it was not just cut lol... so yeah a motor that would do a 9 or 10 inch would be best.

Guess this one weigh lil more it is 3.5 pounds just the plane and servos, no nothing else... I really need to find some different servos for it. it has old old NES Jr servos and there super slow. aierons really not big deal but elevator and rudder servos could be replaced with something else.

With it 3.5lb airframe only, you're realistically going to want 4S.

Assume a 10" prop (10 x 8 or 10 x 10), on 4S you'll want Kv 900-1000 to get about 450-550W, which will be good sports performance with that big 500 sqin wing. To work well at around 500W, look for motors at least 150g in weight

Yeah well 4 cell would be fine, you still think that one motor would be good for it?

No one else had any input on this. I just got it out looking at it again today and want to figure out what to go with on it.

In the spring or summer of 1984 I built a Spickler Quickee 500 and powered it with a direct drive Astro Flight Cobalt 40 using 18 NiCad cells. While my flying buddy, Keith Shaw, had recommended standard size servos for '40-size' aircraft, I wanted to save some weight on what was going to be a pretty heavy plane and chose to use three Futaba S-33 servos. I had 'heard' that the glow Quickie racers were using them. There specifications were; 28.2 x 13 x 29 mm (measured), 27.8 oz-in of torque at 4.8v and they weighed 17g. I never had a servo problem in this relatively heavy and fast airframe.

The photo of the plane is from Jim Zarembski's Silent Power column in the May 1985 issue of Radio Control Modeler. The photo was taken by Tim Bissell at an electric symposium in October of 1984. Peter Waters, Keith Shaw, Art Arro and I were the presenters to the Plymouth Flying Pilgrims.

With those specs I guess some HS81's would be fine.

I'm now flying 2 electric pylon racers - the Eflite Pogo and the Hangar 9 Sundowner - as noted a fair bit less wing area than the Quickie 500 spec, but hopefully comparable enough for some ideas.

The Pogo has the OS 3825-1200 motor, on 4S with an 8x8 prop. A 3300 pack lasts about 4.5 minutes, and it's about a 100mph model. The Sundowner is a little bigger and started off with a Scorpion Sii 3026-1190, which is a bit bigger than the OS motor, also on 8x8 or 9x6. Those are both about 700 watt setups.
When the bearings got a bit noisy in the Scorpion, I saw a couple of 5S 4000 packs doing nothing and wondered what would work... I am using a OS 5010-810 with a 10x10, and though it's a bit bigger and heavier than the Pogo, this is up around 900W and a faster setup.

You should be able to get well over 80mph without spending too much. Assuming you are limited to 10" max props and 4S, this 3548-1100 motor should work OK on 9x6 (about 600W, good duration, pitch speed 92mph) 10 x 7 (about 800W, lots of thrust but only about 88mph pitch speed) through 9x9 (about 720W, 115 mph pitch speed.

Those power levels are pretty high for a 160g motor, but it's in spec and will have no cooling issues bolted to the firewall of the Quickie.

If you were willing to splash a fair bit more money, I think you'd be very happy with the Scorpion 3026-1190 - up to 9x9 on 4S at about 900W, but also capable of using 3S with 10x 8 for sports or 10 x 10 for speed.

You'll want a battery at least 3300mAh if you're getting up around 60-70A, and an 80A ESC

I've suggested the program cards as well as the ESCs asboth brands are good enough that you'll probably end up with several. The YEP you pretty much need it anyway.

There's a lot of ways to skin the cat, but remember you need sufficient pitch speed as well as power. As voltage x Kv x ~ 0.8 is effectively a rev limiter, you'll want cell count x Kv up around 4800 and 8-9" pitch props. 6-7" pitch won't cut it as unless you go to 5 or 6S, motors in the size needed to handle the power don't come with high enough Kv, and you're also pushing up against motor rpm limits. The good thing is that high pitch isn't much of a problem because there is no minimum idle rpm that wants to keep you flying at 40+mph

Here is a review I did of the Sundowner 36, an EF-1 racer that I flew in full race mode on 4S and in sport mode on 3S. The details and prop/battery specs are in the article. Videos show the performance in race mode and sport mode. I'm a fan of the Spickler Quickie 500, and I'll be watching to see your progress.

For economy, I like the Turnigy motor, HK batteries, and 85 Amp ESC.

Thanks for the info. I am going to have to do more research. and figure it out for sure, I do not mind paying more, for more speed but hate to buy and have it not work how I want. I guess i should buy new servos first and then see what the weight is.

With the power systems I've mentioned above, it won't matter much whether the model weighs 5 or 5.5 lbs. I'd just grab some hitec hs 5485 full size servos that will fit where the old servos were. Cheap and plenty fast and strong enough.

the last few posts in this thread might be of interest, re Q-0500s and the 3548/1100 motor
