Default Phoenix Models Tiger 60 Test Flight

First flight of the Phoenix Tiger 60.

This a sports low wing plane originally designed for a 60 2 stroke IC engine. Wingspan is 1.7 metres and weight around the 3.5kg mark although I have not put it on the scales yet. Usual controls plus flaps (included in the kit). Very good quality kit with no problems encountered at all during the assembly. I would have liked to have seen a two-part wing just to make transport a little easier.

I have installed the Tower Pro 4130-6T motor using simple alloy stand-off mounts at the front end. Very easy install with no modifications required to fit the motor.

All the weight was needed up close to the nose, so a hatch was cut just behind the firewall to accommodate the 5S 5000mAH TrueRc battery.

Performance on the 5S pack was acceptable with short take-off runs, loops and rolls etc. However, I will install the 6S for the next flights to provide an increase in performance. Initially used a 13x7 and 14x7 prop (14x7 the preferred option) but I will try a few other sizes with the larger battery pack.

The flight characteristics of the Tiger are excellent and it is very stable in flight, especially when established on approach with the flaps down. Handled the windy conditions with easy and inverted flight required only a touch of down elevator to maintain level.

The only modification of the kit I did was replace the small wheels with some 78mm Dubro light weight ones.

This plane is basically a test-bed to try different combos with the 4130 motor to use in other scale aircraft down the track.

Looks interesting Keith. Your post got me thinking about a Blackhorse model conversion. I have started another thread on that one.

Hi Aussie E flight ,
I just got my Tiger 60 out of the box.
I am using a towerpro 4130 6 T motor with two 11.1V 4200 mah lipos in series .
I would like to know how the batteries were accomodated into the space for the fuel tank in the GLow version ,It would be great if you could post a photo of this set up here.
I have noticed fuselage support member in the space behind the firewall . Hence I feel if I create a hatch I might weaken the area since I would be cutting the lower part of this member.

Hi Keith ,
Well I had a look at your photos posted above and have done the same thing of cutting out a hatch behind the firwall and reinforcing the side wall edges to distribute the load with some strong wooden slats.
It looks ok.
Thanks for the help.

Hello Sai,

Here are a couple more to help. I ran a couple of lengths of square section around the inside edge of the hatch area, and put a length of spruce at the rear for the blind nuts to bind into.

I removed the former, as it was there to support the glow engine fuel tank which is of course, no longer required. I also added an airscoop to the bottom of the hatch increase airflow into the battery area.

Great flyer and plenty of power with the TP outrunner. I am using a TrueRC 6S 5000 for flights of around 15 minutes, with plenty to spare for a missed approach or two.

Hi Kieth ,
Thanks these photos , I started off doing the same thing. Only thing is I have not taken off the supports completely.
I will review my mods based on these photos and post some photos for your comments.
I have another basic doubt : should the ESC be isolated and insulated from the batteries in the hatch?

Hi Keith ,
I was looking for a motor set up for a 40 size plane the VQ Megafly.
What do you think of this :
http://cgi.ebay.com/950rpm-v-BL2826-...742.m153.l1262

Any Idea of Turborix as a brand ?

Sai,

I'm not familiar with the Turborix brand name, but it could just be another brand re-named. I have had great success out of the Tower Pro range and the Turnigy range from United Hobbies. Value for money, I don't think they can be beaten. An excellent 40 size glow replacement is the TowerPro Brushless Outrunner 3520-6 700kv - I have 3 of these in different aircraft. I have just ordered a Great Planes 1/4 scale RV4 and it will most likely be powered by a Turnigy 50-65 350kv motor. Another TP 4130 is going into a Sportsman Aviation Victa Airtourer.

All of my larger aircraft use TP or Turnigy (except for one e-flite Power 46). Check them out before you decide would be my advice.

On the subjuct of the ESC, I run mine against the side of the fuselage past the battery and have not had any problems to date. Always ensure you have adequate over your ESC and battery to give it best chance of cooling and performing at their best. How much air exits the fuselage is just as important as the amount that comes in!!

Good luck, and I hope that helps.

Hi Keith ,
Thanks a lot for the prompt reply and advice.
I will look for the TP 3520-6
Which ESC should I use with this Motor and what is the battery and prop that powers this motor to have decent performance in terms of power.

Hi Keith ,
had a great maiden flight of the Tiger 60 . except I had a problem with the motor mounting screws getting loose thus altering the line of thrust.
Once I get it fixed I think the motor should deliver sufficient power in the right direction .
I am planning to take a video of the plane. Will post it here.
Thanks for all the help it was very very usefull.

Default Phoenix Tiger 60 Electric Conversion

Here are a few photos of the Tiger 60 after conversion and its maiden flight.
Did some minor tweeking after the Maiden still have to do the final and touch up finishing ( hence looks a bit messy in places ) and a video of the flight.
Set up is : TP 4130 13 T BL with a 100 amp ESC and 2 nos 11.1v lipo 4200 mah in series swinging a 13 x 8 prop.

Sai,

Using 2 7.4v batteries in series will give you 14.8v with the same battery capacity as you have said. I have used the 3520 motor with both 14.8v and 18v LiPo and the 18v gives a fantastic leap in performance. Have you looked at the 4000mAH and 5000mAH batteries from United Hobbies and TrueRC? Good value and performance. Higher C rating from the United batteries (Zippy brand). I have just ordered some of their 5000 6S for my Turnigy 50-65 motor in the GP RV-4.

Default Battery usage

Keith ,
I am seriously considering the use of considering using 2 X 14.8v 2200 mah batteries in parallel to have an effective 14.8 v 4400 mah for the TP 3520 motor .
The reason I prefer opting for 2 battery set up is that the chances of both batteries suffering damage in case of a crash is better that damage to a single 5 or 6 s one .
The weight factor is about the same .
What do you think ?

Sai,

There is no reason not use the 2 x 14.8 batteries in parallel to give you the capacity you are want and the reasoning behind using 2 batteries instead of one large battery is very sound. I have lost one 5S pack to a crash (see my post in http://www.wattflyer.com/forums/showthread.php?t=24203) provided the size is right for your installation. I have done this in my Phoenix Rainbox when using 2 x 11.1v 2200mAH packs - it gave me about 30 minutes of flying time!!

If you try the 5S packs though, you will see a big difference in power.

Keith ,
If I want to acheive 5S can I use 1 X 11.1v 20c 3600mAh 3S2P 6 Cells and 1 x 7.4v 20c 3600mAh 2S2P 4 Cells in series . Can we use 2 dissimilar voltage batteries in series with other factors being the same .

Sai,

Apologises for the delay Sai. The short answer to what could be a very involved and in depth question is no. Batteries can be wonderful accessories for us when all is going well, but they can also be a huge pain the neck, so the best way to treat them is keeping everything equal and in balance. Alway use the same voltage and capacity packs when connecting in series or parallel.

In fact, it is even better if you can use 2 new packs right from the start so you know what condition (in theory) your packs are in. It is of course always possible for even new packs to fail or have a faulty cell - if you have them in series your motor will soon let you know by dropping off in perforance almost instantly, where as if you have them in parallel you will suffer a decrease in your flight time.

Always use a good quality balance charger when re-charging your Li Pos.

Default Phoenix Tiger 60 Electric Conversion

A couple of data figures from my Tiger 60L;
  • Tower Pro 4130-6T 477kv;
  • TrueRC 6S 5000mAh battery.

13*6.5 APC prop 41A / 880 watts / 8400 rpm.
15*6 APC prop 48A / 960 watts / 8800 rpm.

Running the 15*6 at the moment. The Tiger is a great sport flyer and handles gusty conditions with ease.

Hi Kieth, I have been reading your posts with a great degree of interest. I have chosen the Tiger 60 as my next plane - (learning on a .46 glow trainer at the mo.) Have flown several electric foamies in the past and feel I would prefer to not have the mess associated with fuel planes. Can you let me (us) know what kind of flight times you are achieving from the 6S 5000mAH combination. I am looking at using the Turnigy SK 50-55-580 motor from HC here http://www.hobbycity.com/hobbycity/s..._580Kv_/_1580w

I don't see the motor you used at the site anymore. A lot of the Towerpro motors seemed to switch labels to Turnigy?

Anyway, please let me know the flight times. The combined weight of the LiPo and BL Motor exceeds the weight of an OS .61 by some margin, this I would guess increases the wing loading. Does the Tiger still fly without bad habits?
Thanks in advance,
Bruce....

Bruce,

I was actually flying the Tiger today at our field - it is a great flyer with no bad habits at all.

It would make an ideal step up from your trainer once you are completly confident. I use the flaps all the time (the exception being very windy conditions) and with the power configuation will easily become airborne on half throttle.

I was running a Zinger 13*10 wooden prop this morning and that seemed to be a good combination as well, but I will drop down to a 13*8 or 13*7 to bring the current down a little.

I have the timer on my DSX9 set for 12 minutes and today I found that I had used just on 50% capacity of the 5000mAH LiPo. That means that I have plenty of scope for a couple of extra circuits or a missed approaches if need be. I do not like to stretch my batteries to their limit.

Don't be too concerned about the weight - the Tiger will handle a little extra and not even notice. Any motor that runs power figures around a 60 2 stroke equivilant will easily fly the Tiger.

I used the same motor in my Victa Airtourer and it proved to be an excellent setup in that plane as well. There is a review in Airborne magazine a few issues ago showing the same plane and motor. Alas, my Victa is no more, but I will be building another one!!

I am not familiar with that particular Turnigy motor, but I have several others which I am very happy with. I am about to test fly my 1/4 scale Graet Planes RV4 with a Turngiy 50-65 350kv motor and HXT 6S5000, and 50-55s in a Great Planes Revolver and the Hanger 9 Piper Pawnee so I have no problems with Turnigy. I have also noticed that there is no link to the TP 4310 anymore.

Hope this helps, and best of luck with the flying.

Aussie, could you give us some more info about the rv-4 and the gp revolver?

I have a turnigy sk 50-65-380 in a senior telly and I love it, and I'm thinking about the 50-55-600 on 6s for my .40rv-4 kit Im building (around revolver size).
What prop are you running on the rv-4 and at what rpm? My 50-65-380 turns a top flite 16x8 at 7200 rpm for 34 amps on 6s.

Hey Guys. I notice that you are putting your batteries in from the bottom? Doesn't it become awkward to have to turn the large plane over every time you change a battery? On one model I suspect the wing has to come off to change said battery.
I found it easy to cut the tank area top off,... carefully from just in front of the canopy. then insert a tray in the tank area, with screws, with enough room under the tray to velcro the speed controller to the underside of the tray. The top I cut off, I reinforced with shaped balsa and clip it back on with magnets. If you are interested, I could take some photo's to show you.
I really enjoyed your comments, as it helped me to decide on a tiger 60...... We have a lot of windy days at our field. (Noarlunga model aero sport club).
I also fly calmato 40's and sky raider 40's. I have 2 of each so I can fly 1 while I am fixing the other 1.(Wind and trees).

Best regards to you all,

Fabio.
