Attached is a screenshot from FlightView of one my flights with a stock (receiver and battery connecters have been changed) Phoenix II, using the included battery. The weather was extremely calm, no lift or sink anywhere.

Description:

I was able to achieve a climb rate of 1042 ft/min of a 25 second period during this flight. I typically get around 1000 ft/min climbing somewhere close to a 45 degree angle.

That was VERY helpful. so 1000 feet/minute = 500 in 30 seconds, maybe a little more accounting for voltage sag as the climb contiues. So let's say you could hit about 550 feet in 30 seconds or about 160 meters, all very round numbers.

That is about 20 meters short of a stock Radian and about the same as a stock Radian Pro.

Now the question is what is the amperage to do that and can the stock ESC and motor handle more? The Radian and Pro have 30 amp ESC, so people have been upping the props a little to get them to about 20 to 22 amps to hit the altitude target. I think the Phoenix II has an 18 amp ESC so you would need to change the prop and the ESC if you upped the prop.

Not knocking anything. Just looking at what it would take to make the Phoenix II more competitive in the climb with the least investment or modification to make it more attractive to pilots interested in ALES. I have no idea how well it thermals. That is a different question.

What is the stock prop on the Phoenix II? What is the stock battery size and C rating?

The stock battery is 1500mAh and has not visible C rating. Based on physical size, I would estimate it to be less that 15C. I forgot to check the prop size.

If memory servers me correctly, the motor was pulling 18 amps when static tested using a bench power supply. The ESC heated up quickly, but the motor remained cool. I believe the motor can take a larger prop, but not the ESC.

Pheonix 2 for ALES

We have a growing group and a field about 1/4 miles from my house that has recently gone buggy for ALES type of fun. Although I have been away from gliders for about 15 years and have only been flying my DW Foamies 40 inch 3D Extra 300. I have become a HUGE fan of foam airplanes! (something that I turned my nose up at10 years ago). Times have changed!

Anyway. I have my eye on this airplane as a beginner entry into ALES type of fun. Lighter than the Radian Pro. (I prefer ailerons as I am used to the set up). (and they look way cooler). Aileron plug ins connect easier, spare wings and fuse are available.

Looks like a winner. Looking forward to any experiences out there with this plane vs the other foamy gliders in ALES competition. I think that this model will be my next airplane.

Has anyone tried different props or batteries on the Phoneix 2 to see if it can achieve a better climb with only a prop/battery change?

I had exchanged e-mail with Hobby People about having them test out the set-up for higer amps to get a better climb but they have not gotten back to me with any test results.

Also, how well does this bird thermal compared to Easy Glider Pro, Radian or Radian Pro?

Sorry to bump.

My Phoenix II stock motor is dead. Can someone help me with finding a replacement. I'm okay with upgrading the esc and prop for a beefier motor. Any help would be appreciated.

Anyone got anything used that might work?

Phoenix Motor

Milktruck - check out Altitude Hobbies web site (http://altitudehobbies.com/). I just ordered a Suppo 2814/8 motor for my almost new Phase 3 Phoenix. The stock motor performs nicely but it is a bit weak for ALES events. The 2814 is a stronger replacement for the Radian/Radian-Pro 480 motor. Somewhere in the range of 350 watts. You'll need at least a 40 amp ESC. This is a sailplane so the new motor and 40 amp ESC should be used for climbs to altitude, not extended powered flights.

The Phoenix stock prop, spinner and adaptor was lost on the second flight (I didn't check the set screw) so I tried a stock Radian setup. Fit was perfect and the performance is about the same as with the stock setup.

By the way I weighed both my Radian-Pro and the Phoenix and found the Phoenix is 1.2 ounces heavier at 35.4 ounces, ready to fly, with a slightly smaller motor then the R-Pro. Both planes thermal about equally so the Phoenix gets the nod from me.

My Phoenix needed several minor tweaks (ESC cooling, pushrod flex, canopy attachment, etc.) but overall a real nice model.

Hope this helps,
Ray

Have fun and enjoy your flying. That is all you will need to do. The newer versions of the Phoenix II have Magnets for the canopy already installed.

I picked up a used Phoenix II from a buddy and had an excellent day yesterday learning how to fly in pretty gusty winds while most were on the ground. While learning how to hand launch I did a couple of loops that beat up the nose a little and needed some repairs. Right back out on the afternoon and evening for a couple more flights to test out the repairs. Everything worked nice so I spent the evening setting it up with a gopro hero 3 (in case) in the belly.

This morning, I did a couple of laps around the field and then it went into a spiral that I couldn't recover.

I left the sound on in the video and you can hear a loud Pop at 6 seconds. I tried high rate, low rate switch but no luck. A quick test on the field showed the servos were still working. Who knows...maybe my repair or camera modification or just and old servo caused an issue.

So anybody try burning one of these things to make it rise?

I donated it to one of our locals that has over 40 planes and time to rebuild and test.I'm going shopping.

These gliders make for excellent camera platforms they are so steady and slow. Also great for me since I've only been flying about 3 weeks.

Enjoy it, and bring some water, you'll be up for a while

* Owners Report *

Going on two years now flying this wonderful model! I can't believe it! It does not seem that long.
Sadly about a month ago I completely screwed up while flying on the slope and lawn darted my Phoenix II into the face of a slope. The crash destroyed the nose of the aircraft.

The bright side. I picked up a new fuselage to rebuild my Phoenix II. I enjoy this glider that much. I have noticed several improvements to the glider. For one the fuse is a few ounces lighter than the first gen. The second change I noticed was the thrust line of the motor. That has changed so that the glider does not climb as aggressive on power like the first gen did.

I am now at 312 flights on this bird 2 years later. I hope to get another 2 year out of this great flying glider.

Anyone else out there still flying the Phoenix II ?
