I had an Osiris 47, and replaced it with a World Models Super Tai Ji. Not bad.

http://www.rcuniverse.com/magazine/a...rticle_id=1446

Super Tai Ji looks a nice plane. How did it compare to Osiris 47" ?

Lots of interesting options popping up here. Not sure if my puny 700w power system is enough for the Rainbow or Super Taiji?
So far the ML400 is looking like my answer but that Rainbow looks cool!

I've only been flying for a few months and so don't consider myself nuanced enough to know the difference yet, but at my level, they seem very similar.

One thing about the Tai Ji is that the battery compartment is small and there's not a lot of room to move the battery around to adjust balance. People have resorted to moving the servos from the tray in the front to positions in the rear, or adding weight to the tail. That was not necessary in the Osiris. The fit and finish seem pretty good. There are some nice touches in the design. The guy at Airborne Models is helpful and responsive. Go over all the joints, especially near the LG, with glue.

There's a pretty good [link=http://www.rcgroups.com/forums/showthread.php?t=1516967]thread[/link] over on RC Groups about this plane, and some of the participants, who are more experienced than I, have had both the Osiris and the Tai Ji. Check it out.

Did we forget about the Sequence?

<span style="font-size: medium">NOW, THAT GREAT PLANES SEQUENCE F3A -LOOKS REALLY NICE ...
</span> -did not really know about this plane ... How does it fly ?

I note it is: wingspan 50" -1270mm; Weight 3.5 - 3.75 lb/ 1590 - 1700 g. Is only $159.99
Fits in between 30-size and 50-size ...
So is really a 40-size plane ...

Uses a RimFire .32 motor - Weight: 7oz (198g) andKv800; D42 L50
-So motor is also in between a 30 and 50 size motor...

A very similar motor would be the Turnigy SK3 4240-740kv, 10T (208g) -which is exactly the same motor as Hacker A40-10 S Kv 750

NICE ...

There is a lot of information on this plane:
RCU Build Article: http://www.rcuniverse.com/magazine/a...rticle_id=1169
RCU Thread: http://www.rcuniverse.com/forum/m_90..._1/key_/tm.htm

I did take a look at that one. There is a very long thread here and after reading all of it there seems to be a large variation in quality. Many loved it and many had problems losing canopies and cowls. Severe warps and terrible covering we're also frequently mentioned. Given the price and all of the Tower coupons it could be great if you luck out and get a good one.

The real problem now is F3A unlimited just dropped the price of the Monolog 70 making me seriously consider upgrading to a larger plane. Unfortunately my winter field has a very tight overfly and I could imagine a larger plane being flown too big.

Yes, $175.00 is great price for this plane... (in the UK, it is <span style="font-size: small">&pound;143.20 =$218 </span>... - http://www.bondaero.co.uk/product/monolog70 )
-I have Monolog 110, love it ...

For this Monolog 70, NODOUBT ABOUT IT: I would use <span style="font-size: medium">Turnigy SK3 5055-320kv (369g)orGens ACE Mars BL4850-340KV(370g)</span>
-with 6S LiPo
-These two motors are almost IDENTICAL to Hacker A50-16 S motor -but cost only $49, 1/3 the price of the Hacker.
-Except they have a 5030 stator and they will be more powerful than the Hacker
-These 2 motors are identical to each other
-And are made in the Sunray Tech factory along with Hacker, Torque, Z-Hyperion;and LiPolice, OK Hobby Infinite, Shulman Aviation FURY,Common-Sense-RC etcetc etc

-And I would also use a Turnigy dlux 80A ESC -which is also made by Sunray Tech -and better than a Hacker or other ESC ... and is only a fraction the price ...

Cheers. Good Luck.

The Commander 40 was on display at Toledo today, totally worth looking at. RTF version available for $160 - really nice quality, nice lines, a lot of attention to detail. It is basically a foam version of the Super Tai Ji.
http://www.thewingsmaker.com/

Yes,that COMMANDER EP 40 -Looks like a nice plane
Notice there is RCG thread about it - http://www.rcgroups.com/forums/showthread.php?t=1786321
-some seem to prefer it, to Super Taiji 40 EP

Something else also caught my eye - the blue/black motor that World Models supply for this plane:
-the "Outrunner 37/48 Deluxe Motor 40" ~172g, Kv 770, D37 L48 (some webpages show it as Kv 750) -also called a KM0 3748-11 motor ...</p>

<span style="font-size: medium">The World Models "Outrunner 37/48 Deluxe Motor 40"
</span> There are very good pics of this motor at: http://www.servoshop.co.uk/index.php?pid=KM0374811 (see bottom of page)</p>

Also: This World Models 37/48 motor has a VERY similar "look" to the:Sonic Electric 3525-810 (this motor is also 37mm diam, 48mm long; it has a 3025 stator; the name "3525" comes from a combination of the approximate external diameter, and the length of the stator ...)
see: http://www.sonicelectric.com/Merchan...de=SE-3525-810
-this Sonic Electric motor is also a "3748" on external dimensions, has same weight ~178g as the WM one, and a very close quoted Kv of 810.
The two motors have a slightly different style front housing -but we know that one single factory can often produce motors with a slight difference in end housings -when the the actual motor underneath is <u><span style="font-size: small">exactly</span></u> the same ... e.g. http://www.rcuniverse.com/forum/fb.asp?m=11449011</p>

The front housing style of the World Models 37/48 motor is, however, very similar to the style of the Foxy C3025/12 motor
see: http://www.puffinmodels.com/product.php?prod=2150-and this is another 3748 motor,and this one has EXACTLY the same quoted Kv of 770, and weight, as the World Models motor ...</p>

NOW: the interesting thing is that we KNOW that both the Foxy and the Sonic Electric motors are made by the SunRay Technology factory ...
-and so it looks very much like this World Models 37/48 motor is also made by SunRay Technology.
One of the "give aways" of being a Sunray Tech-made motor is a brass washer and horse-shoe &lsquo;C&rsquo; clip on the shaft just outside the front housing -and the World Models 37/48 motor has exactly this feature ..- http://www.rcuniverse.com/forum/fb.asp?m=11426913</p>

-Since this World Models motor will therefore be completely identical (internally)to the Foxy C3025/12 to and the Sonic Electric 3525-810: - Then it is also EXACTLY THE SAME IDENTICAL motor (internally) as these following 3748 motors: Hacker A30-12 XL Kv 700 =Torque 2812T/720, 12T, Kv 720 =HYPERION Z3025-12T 665 KV =Turnigy SK3 3548-700kv, 12T =LiPoliceLP-3025/12T-770KV=Infinite A3025-770, 12T
- http://www.rcuniverse.com/forum/fb.asp?m=11427116</p>

This World Models 37/48 motor costs $48.90at: http://www.rc711.com/shop/outrunner-...ne-p-2585.html
-whereas the Hacker A30-12 XL costs $113.32 (anywhere in Europe)
However, the Sonic Electric 3525-810 motor only costs $54.95

<span style="font-size: small">The World Models 37/48 motoris only 43% of the <u><span style="font-size: medium">totally identical</span></u> Hacker A30motor -and the Sonic Electric is just 48% of the Hacker A30 ....
</span>
-And also I note this World Models 37/48 motor can be bought on eBay: for just$49.99

Dr Motor, please stop invading every thread with these broken logic equations that claim these motors are all identical - YOU CAN NOT PROVE THIS BEYOND REASONABLE DOUBT. How do you know the copper windings are the same exact copper, wound with the same tension, the same pattern,? How do you know they all have the exact same bearings, with the exact same lubricant, with roller balls of the exact same material? How do you know these all went through the same quality checks? How do you know the strand counts are the same in the wires? How do you know the solder is the same chemical composition? I could go on, but I hope you get the point.

Everyone here gets your point that these motors may likely be made in the same place, and that companies like Hacker may possibly be charging more money for the exact same motor.

YOUR POINT IS UNDERSTOOD, YOUR LOGIC IS FLAWED, SO PLEASE STOP, IT IS FREAKING ANNOYING.

Why don't you just start your own thread about motors - when topics like this 4S practice plane come up, you can do your little research and add to your list, and you would be creating a resource for people who actually cared to know about this. It is not right to take over threads of different topics and turn them all into these illogical motor debates.

Hello Joe, I have done exactly that; <span style="font-size: small">see: </span><span style="font-size: small">http://www.rcuniverse.com/forum/m_11426913/tm.htm</span><span style="font-size: small">
</span>

Joe: Let me point this out: Indeed,<span style="font-size: small"> I <u>CAN</u>prove they are ALL totally identical motors ....</span>
Formal objective, very careful and very thoroughscientific testing of: Hacker, Hyperion-Z, Foxy, Gens Ace, &amp; Turnigy SK3 motors
in the sizes from 1709 stator, to 3020 stator, to 4025 stator (-and I will soon test 5025 motors -i.e. A60-size ones)
<span style="font-size: small">has shown that they are ALL totally identical absolutely the EXACT SAME motors....
</span>
<span style="font-size: small"> -On the Motor Thrust Test stand,Hacker, Hyperion-Z, Foxy, Gens Ace, &amp; Turnigy SK3 motors <u><span style="font-size: medium">ALL</span></u> give absolutely indistinguishable readings for current, watts, RPM, Thrust -for 7 given props which I have tested for allmotors ... </span><span style="font-size: x-small">(seehttp://www.rcuniverse.com/forum/m_11463161/tm.htm for details of test stand )</span>

Also -they all have EXACTLY the same bearings,exactly the same windings, exactly the same magnets, -in many cases the same identicalX-mount and prop apaptors <span style="font-size: small">-INSIDE, ALL THESE MOTORS ARE COMPLETELY AND TOTALLY IDENTICAL</span>, Joe

I will be publishing all these results on RCUsoon, just as soon as I can write them up, do appropriate graphs etc ..

Also see:http://www.rcuniverse.com/forum/fb.asp?m=11465548 which shows the Hacker A30-12 L, 1000Kv is IDENTICAL to the Turnigy SK3 3542, 1000Kv motor
<span style="font-size: small"> -I have manymany, more resultsjust like this, I have done 5 runs in each motor, and they both give EXACTLY the same readings for everything .. absolutely everything ...

</span> I am afraid the conclusion is inescapable:
<span style="font-size: medium">That underneath the outer shell, the Hacker, Hyperion-Z, Foxy, Gens Ace, &amp; Turnigy SK3 motors are <u>ALL TOTALLY IDENTICAL EXACTLY THE SAME MOTOR
</u>
QED, Joe

Just finished a ML 400
<a href="http://www.f3aunlimited.com/webstore/index.php?main_page=product_info&amp;cPath=8_70&am p;products_id=595">http://www.f3aunlimited.com/webstore...roducts_id=595
</a>I'm really happy with the results can't wait to fly it.
I'm pretty confident that I have a rockin setup to get er to fly with the authority that's usually missing in these smaller planes.
Notor is a G Force 32 with a Hobbywing Opti 60A esc. Looks like it has a ton of power.
The WS is 47" and length 49".
Now I have to wait for a good day to test.
We've been looking for a small plane that actually simulate a larger model. So far all have been a disappointment.
Fingers crossed. Mike

<span style="font-size: medium">Looks REALLY nice, Mike
</span> -Looks like the canopy is further forward, than on previous versions of the Monolog 400

The GForce G32 (4250-800KV) is 214g, D42 L50 -it will have a 3520 stator

Other same-size 42mm ext diam motors to consider are:
Turnigy SK3 4240-530kv, 14T
Turnigy SK3 4240-620kv, 12T
Turnigy SK3 4240-740kv, 10T -these are all 195g</p>

Also more expensive ones, which are the exact same motor as Turnigy SK3:
Hacker A40-14 S V2, Kv 530, 14T
Hacker A40-12 S V2, Kv 610, 12T
Hacker A40-10 S V2, Kv 750, 10T -these are all 208g</p>

and also the:
O.S. OMA-5010 Kv 810,
this is 234g, has a 4010 stator, and is a 50mm ext diam motor

see: http://www.rcuniverse.com/forum/fb.asp?m=11428699</p>

Thanks Dr Motor for all the suggestions.
It looks better than the earlier versions.BJ Craftmadewith it with 2 options. One is for3D and one for pattern. We only stocked the patternversion.
At $150 it's a real value.
This plane is the first and I have had many of smaller practice planes to give me the feeling I desire.
It flys like a big plane. The motor I put into is is hot!!! Power is amazing on a 4S 3300 30Cpack.
The only thing I didn't like is the canopy attachment spring. I'll put a better latch on it soon.
For now I'm really pleased. Mike Mueller

..and I imagine this bird will make it out to some contests for public viewing?

Yes Joe as long as I stop killing it like I did the other night. Our field is a mess from the winter and the rains and it has not been kind on landings. Oppss!!!!

Well at least that's what 4S planes are for!

Mike,
Will this accommodate a 4S TP 3900 ? I have a good supply of batteries, ESC and motors that I use in U/C Electric Stunt that make this an interesting /inexpensive practice aircraft.

Do you feel a Horizon E-32 would suffice in the power department ?

Thanks

Yes that E-flite 32 would work just fine. The one thing that needs to be said is that these planes fly best when kept light. I wouldn't go any larger on the battery on this size of plane, of course that also depends on the pattern you're flying. As a point of reference I'm flying a 6 lb. plane with about 1200 watts power and I can fly say the AMA Sportsman in under 8 minutes and my 6S 3.3 mAh 40C pak reads approximately 3.8 volts per cell after flight. What has work best for me has be to keep voltage 3.8 volts on the cells after sequence completion.

Hi Frank,

The only downside to that power 32 is its weight. I used an 800kv Fury motor in my Vanquish but it is only 143g and happily spun a 12*8 putting out 700W. The batteries also might be a little heavy. I used 40c 2650mah 4s packs and was able to complete a full P/F sequence and usually one or two maneuvers in 6 or 7 minutes. I did fly in a little but my auw was a little over 3 lbs.

Too much going on to mess with practice planes now. I plan on ordering a ML400 after the Nats when all the other stuff settles.

Hi Anthony,

I agree that the E-32 is on the heavy side. I have one in use and also have a supply of 5S 3300 packs which I'm currently using for U/C stunt.
The E-32 has over 100 flights and works just fine with a CC Phoenix 45 ESC. The 32, from what I've heard, can get by with 4S.

Like you, I want to stay with the setups I already have. My cellar already has enough lipos. For that reason, my preference would be to use 4S in a mini-pattern bird. As we all know, they are generally lightweight and cheap and charge up quick.

The new, improved Vanquish has my attention, too. I especially like the fact that it has an airfoiled tail group . I've yet to compare wing area, weight, and size of battery compartment. That'll be the clincher for me. The ML 400 is also quite capable- the landing gear seems , well...

You are right when you say that its time to focus on 2M while we're in that season.

Frank
