I am ready to build my l39 ...i read this system is well balanced but does not perform as well as stock motor and fan...They also have a 3s alloy setup which is my first choice http://hobbyking.com/hobbyking/store..._Version_.html I am looking for more power than stock if possible.... I want to stick with 3s ...thax

Screamer LG

Anybody rig their Screamer with landing gear? I'm going to use the mains off
of a Nitroplanes Mini X, but I'm debating on wether to use a modified SA nosewheel, or a main off on a PZ UM P-51. Comments please.

AMX - Tailerons Only?

Picked up an AMX airframe from Hobbyking. Wondering if anyone has tried tailerons only (ie pinned ailerons)?

My experience with the F-18 is that it flies better this way, so interested to hear the views of others.

I tried pinning the ailerons on the F-16 and was disappointed in the roll rate or lack thereof. Not much surface area on the elevon setup. I suppose the F-18 and AMX might be different.

Well, with a balanced impeller, it has enough thrust to stay in the air even at 30% throttle. In that flight I ran it at around 35% because the battery was too far forward and I had to compensate with too much elevator and it would loose altitude and speed at 30%. I will try this again, but will move the battery a couple mm back to avoind inputting too much elevator and thus creating less draw and increasing flight speed, and hopefully flight time above 11 mins. At 30% throttle the motor draws around 5.5 amps (at least in the static test, it is possible for that number to be a bit lower in the air).

I've gotten 8 mins 30 secs with some full throttle blasts, but this time I decided to see how long it will go it I just set the throttle in one position and keep it there until the li-po alarm sounded at 3.5 volts per cell, under load. I run 3s li-pos, and I can only assume the 4s will take it down quicker, due to the higher weight.

Hatetocrash: I have the 3s version of that alloy edf HK sells, and in a word: dissappointed. Stock fan is as good, or better on 3s. These are heavier, but look cool. I have one I run on 4s, just to get the f-86 in the air. Pretty lackluster, really. I would maybe get the 4s dr mad thrust one.....----Metalguy

Everybody is talking about the Dr. Mad Thrust edf unit - please someone get it soon and test it, and SHARE the results. I've got a bad itch to order one, but dont want to make the jet heavier unless the unit really delivers the stated specs.

I hear you...so stock fan is the way to go...i wonder if there is a motor from HK that fits stock fan that would be a superior power plant compared to stock motor on 3s...? i don't need a rocket just a setup with a little more punch...Like better power and another 10mph speed... I will be using a 30amp esc so watts need to be around 300 max...i am not sure what stock motor watt draw is on 3s? any help is appreciated...i will be fixing my f9f also so i will need 2 edf systems...thax

The stock motor on my T -45 reaches around 230W at WOT on a 3s.

you should always say WHAT lipo it is - I assume you are talking about a 40C 1000mA lipo - it will be quite a lot less with a cheapo 850mA 20 or 25C lipo - then it's more like 180W settled on a full lipo. Even better: stating the Volts, not only the Watts. BTW you asked again for the Dr Max Thrust aka Lander aka Cyclone Power 3300kV 10-blade alloy data. I gave them twice, that should do

The Turnigy 4800kv or 5000kv EDF series 2610 .... but you need to cut back the motor mount tube to allow the Turnigy to sit in. The JPowers stock motor is longer in the shaft extension at front.
Second - you swap shafts between the motors to fit stock fan.

Tip : If you do this change - stock LiPo size will not be enough as amps draw whatever route you take will increase .......

The stock motor and above Turnigy's are all 4S capable.

I run the 5000kv in stock shroud but with 6 blade rotor from the $3 EDF from HK. I also use a 1600 4S 35C Compact LiPo ...... about as fast as you'll get on a 'budget' in the T45.

How far back did you give that info? I tried to read from the 100th page, but i just couldn't take it and just moved to the latest.

I am using a Nano tech 1000mAh 3s 45c lipo. Can't really say what the voltage was, but it drew just over 19 amps and the watts were at around 230. I will have to start filming the watt meter tests for later reviewing.

They are some really good packs for me thus far! Just order from the USA warehouse and get them in as little as 3 days! I love not having to swap out the deans plugs!!

There is a little more weight but the performance is way better! I am getting much more punch with these batteries even when compared to Gens Ace which were pretty awesome to begin with!

So far to date my fastest shipping time has been 2 days from time of ordering. I am only a couple hundred miles from the warehouse so it shows pretty quick.

the one factor that u get and pay for in a inrunner is a factory balanced motor, typically.

chuck.
I really don't have an answer to the questions. But in my experience the outrunners with the same size and KV draw higher amps. The RPMS will be similar.

Out of all the 50mm jets that I have had the L-39, t-45, F-16 and Katana fly really well on stock 3s set ups. You really don't need to upgrade the power on any of them as they are since the seem to be perfectly matched to the fans that come with it.If you want to great 3s set up the Himax is a good upgrade and can use the same size battery as stock. The only downside is that it is $60. Don's Wicked set ups are good as well but you need bigger batteries to match. Fly the L-39 stock and see how you like it. You may not need to change at all. It flies really well with stock set up.

The AMX is a different beast! No where near what the F-18 does. The AMX will do great with the tail moving only and the main wing pinned. I opted not to but the surfaces on the wing barely moved at all. The tail was doing all of the work for the most part.
