How does the 2S LIPO compare to a 6 or 7 cell NICAD. (Weighs less with more MAH but likely has less voltage than a 7 cell NICad so what is net performance.)

LiPos are much lighter than NiCads or NiMHs.

As far as voltages, NiMH and NiCad cells are 1.2 volts per cell - LiPos are 3.7 volts per cell - so, in order to have somewhat the equivalent Volts (which is what "pushes" amps through the circuit) you will need 6.16 heavy cells vs 2 lighter LiPo cells for the same amount of power if the amps are the same (P=IE)...

Performance should be better in the lighter airplane...

However - 7 cell NiCad with 8.4V will provide 28% more watts than 2S 7.4V LIPO.

So the question is whether the reduced weight of LIPO offsets power loss of lower voltage.

Test it... it has been my experience that lighter weight improves performance a lot more than a few volts extra from the Nicads. Also, the delivery of power from a Lipo pack seems to be better.

Have fun...

Multiples EZ Glider Pro with Scorpion, CC Phoenix and 2200 pack. First sailplane and loving it. Nice and relaxing after flying the helis. Love the way it go vertical.

Just finished a BOT ARF conversion to electric and it's ready for shakedowns. The Watt-BOT was a scratch and dent special and needed a bit of work other than the conversion. The covering was messed up in quite a few spots on the wing and I didn't care for the original color scheme. So off it all came from the wing and horizontal stab and on went new. The servo for the flying stab was moved forward to under the wing with the rudder servo and a new pushrod and bellcrank setup installed.

Spoilers were cut into the inner wing panels before recovering and each has a micro servo for opening them. Power is a Head Up R/C 3542-10 BL outrunner with 40 amp ESC swinging a AeroNaut Cam 11 x 6 folder. Amps are supplied by a Maxamp 2100 maH 25 C LiPo. A couple test flights with this setup proved this to be plenty of power. She isn't a rocket,but don't waste any time either. The transparent yellow with red trim Mono-Kote is easy to see with the yellow almost glowing when backlit a bit. Balance was no problem requiring only 2 oz. to bring her to specs. She weighs in at 70 oz. putting her 10 oz over the stock weight,but still only has a wing loading of 8.5 oz./sq.ft.

Default Condor

I got an old Scorpio Condor Magic 29 at a swap meet early this year and am just now getting some parts to get it going.

It needs a motor and a servo and some slight repairs. I'm adding a wheel and some skids on the wing tips and tail. I'm also going to beef up the wing attachment points. Then I might add some paint instead of the plain white that it is.

I plan on putting an E-flite Park 480 with an 11x7 folding prop in this glider. The chart says it should fly with this.

Hope it flies good... It's a big one - 2.9 meter wingspan.

Since my last entry, I purchased a 74" span glider which I believe was kitted by Airtronics a numbr of years ago. The person I bought it from has had to get out of the sport/hobby with advanced CPD Has a Medallion .049 in the nose.

Maybe not technically a glider or sailplane, but I've started to recover my old Lanzo R/C Stick. 9' span, about 1184 square inchs area. Used to have an old Fox .59 on it, but I will be replacing the Fox with an older Saito .52. The chart says the Saito should spin a 13 -4 prop about the same RPM as the Brown Jr I believe Lanzo used back in 1936. I've seen these planes get hour+ flights with only about 5/8 ounce fuel at SAM contests.

Default My babies...

I live near a somewhat massive soccer field, my hometown glider is none other than the Speedo 1200mm from Revolution shop, I have been wanting to do a proper review on it, however, I 've got a really good camera but I fly solo and the winds are not very forgiving at low levels... I'll do a full write up later at some point to help out other owners.. great little thing, handles wind like a champ, I'm using a Futaba 9CAP with zero speed offset (its an RG15, its going to get a little draggy for sure) however, fast fast fun...

Now if and when I end up at a bigger field, I use two more Revolution shop gliders, the passer-x, it floats, quite simply its beautiful, sleek, and zooms and loops and does all the fancy stuff...

The other one I fly is actually, thanks to the courtesy of Revolution shop, the prototype Bulero Pro Hi-Wind... its a very casual flyer, VERY capable, fun, light, and beautiful... I have landed this one during sunset, beautiful, final approach looks like a hawk coming in... this one I will recommend like crazy to anyone, its not a euro glass slipper, but oh my, delightfully ol skool yet so contermporary at the same time..

Keep in mind, none of these are dlg type launch gliders, they're easily adaptable to ol' high start however, they're pretty much enjoyable in javelin toss form...

Once again I'm terribly sorry, I fly alone, ergo no in flight pics...

The blue and yellow plane is my 2meter Electra ARF with a Graupner speed 600 race also running on 8 cells but a Sub C pack.

The big white scale thingy is my 5 meter Nimbus. Still haven't figured out how to get that one in the air but she'll probably get a slimer on a pod or something.

Then the in flight yellow and balsa colored one is my Quickflick IID scratchbuilt discus launch glider designed by my good friend Paul Daniels in Aus. More info on this one can be gotten from me as short kits are now available for the lucky folks in the states. I am working on a Eflite park 370 outrunner powered fuselage for this one.

Other than these I fly a bunch of slope gliders mostly wings.
Sweet gliders! Do you have any video's of them flying?

My latest sailplane is a Spirit 100 converted to electrical power. The battery will sit on a platform under the canopy and above the servos. The plan for this conversion was not to gain long duration cruise but to use the motor instead of a High Start to boost the acft to sailing height. Using a 1300 mAh lipo, the hope is to get 2 to 3 boosts/battery. Conversion's AUW added just a very few oz's to the unpowered version's. CG fell right into place with no adjustments (dead weight) needed. Still need to add cooling provisions. It has the capability of deploying crow configuration.

Here are mine. The Graupner Electro Jr. was my first. It is ancient by model standards.

I can't believe I haven't posted my e-BoT here!

So here she is. I electrified her with a AXI2820/10 in the nose, swinging a Graupner 12x6 CAM, getting juice from a 3S2250 Zippy through a JES40 ESC. I also installed 2 spoilers with a micro servo each.
I added some blue stripes to the bottom of the wing, the elevator is removable for easy transportation, and both elevator and rudder servos are up front.

She flies like a dream.

I think your wife is right. You should pack up 5 of them and send them to me.

hello AEAJR,
-----You should pack up 5 of them and send them to me.---
then i have only 45 gliders left ... and must take one of the 40 motor-planes
and what should i do if i am old and finish my job? (in 2 years)
may be ... back to the roots ...balsa woodcrafter

I'm flying a 20+ yr old Gentle Lady with a Slimer .061 (throttled) on the nose and a Wright Brothers RC "Gambler" DLG. The GL is great for gettin high and thermalling and the Gambler is just plain F-U-N!!!!!!!!!!!!!!!!!!!!!!!

I have 3. An ARF I can't remember the name of, a GP Spirit, and a Riser. My first 2 meter was a Gentle Lady. She bit the dust when a strong crosswind flipped her on the high start! BOOM! Balsa confetti!
