An excellent parkflyer sized EDF jet (EPO). The jet comes 95% pre-built and comes with EDF Unit and steerable nose wheel.
Because this jet is made from EPO, it is very resistant to breakage and will literally bounce in light crashes. The material is also easily repairable and quite flexible.
just pulled this model out of the box great looking jet, I'm trading out the stock edf fan and using a 12 blade unit with a cyclone 2800kv motor, 85 amp esc with 4s battery...looking for speed,,has anyone put retracts on this jet yet?
Hey Craig....watched your video-great....would you recommend this jet to experienced pilots who have mostly flown prop planes ? I recently got a E-Flite UMX Mig 15 EDF Jet which is a micro& enjoy that!
Yes I would. It is very stable and flies like its on rails. I fly mostly prop planes . This is my second edf. My first is the zephyr v70. As long as u set ur elevator throw about 10mm higher and Ailerons neutral, get c of g correct she flie like a dream
Thanks Craig....does this fighter jet come with setup instructions for control surfaces & TX ? If not could you send me a copy of your setup etc etc as I'm looking to purchase this jet.....cheers
Hi pasqua. No it's just th plane and fan unit. My setup: turnigy 2836 3700kv motor turnigy plush 80amp 2 metal gear servos of ur choice and 2200 mah 4s battery. Cut out foam to inside of back of fuselage to slide battery back because of c of g. And just make sure ailerons neutral and elevator up approx 10mm and she'll fly like a dream
Can you please clarify Ails neutral & elevator up approx 10mm ? I finally received the F16 & has 2 servo hsgs which I believe you connect the ails & elev rods onto the same servo arms. Elev rods connect on the farthest servo hole & ails on the most closest servo holes from the centre. Is this correct? Atm I have the Tx setup on elevons...this correct ? Cheers....much appreciate your help!
Thanks heaps Craig....I have last questions for ya....for the CG (4" back from leading edge)should it be slightly nose heavy ? And also you mentioned that ails to be neutral & elev to be 10mm...what would you say max ails deflection acceptable as they are linked to closest servo hole linkage?
Cheers
All planes should b slightly nose heavy. On each servo hole mine r elevator on top hole and ailerons in the next hole. If u think about it. It's common sense. It's up to u on how u want to put them. The nearer u go to the actual servo. The more sensitive it becomes
Hey Craig....I have successfully maidened my F16 without crashing. But came across interesting flying performance which you may of encountered yourself. At full throttle it seemed nose heavy wanting to pitch down drastically but after trimming flew as you suggested but when coming in to land it was wanting to pitch up quite a bit. At this point i'm not sure if I have too much weight in front of CG or if it is a thrust issue ! I was thinking to shift the battery back further even tho I am exposing a hole in the duct inlet to finely balance the CG to be less nose heavy! What do you recon ? Cheers
This plane is amazing. It's cheap and flies great. The c of g is 4 inches back from leading edge of the wing. I carved some foam out of the back of canopy to get my 4s 2200 mah back far enough and it hand launches great. I really recommend this plane to experienced rc pilots. It's a blast
What is the weight of airframe only? I am thinking 4 x 12g servo / 250g of RC lander's old 68mm edf (4370KV for 3S) / 3S-2.2Ahr Batt. I need enough t/w ratio over 1:1 because I have to do a hand launch. Is this set-up O.K for normal flight without CofG issue? Your advice from experience would be appreciated.
680ｇ* *with out battery.
should use 9gx2 servos
250g EDF is too big
I m using 120g EDF on thrust 1360g for 4s 2650mah
F16 is include battery 1010g and hund launch.
Aditya Agrawal the jet comes 95% pre-built and comes with EDF Unit and steerable nose wheel. The EDF Unit: 70mm (Included). I hope this helps. Also you have to buy or supply your own motor.
Anyone fitted retracts to this model?, I am thinking about the Micro Pneumatic set: (PRODUCT ID: LG-9-0001-S) with suitably tuned main legs. I have done this with an IC F16, but lots more room of course.
any comments?
Thanks
How should the sticking be mounted? Aileron and tail (height) are mounted to one servo per side. Should aileron and tail move to the same direction ? If yes, does aileron need to do as less as possible (closest to servo centre) ?
Does anyone have any commendations for motor/edf unit for this? 3200Kv for 3S seems to be a bit low and HK doesn't even have a 3200kv motor with a 4mm shaft for the 70mm edf. I suspect the combo motors are not the ideal choice. I am planning to use 3S/2200 batteries and a Plush 60amp ESC.
Would the 2627 4200kv edf motor coupled with a 64mm edf make sense?
From my understanding - at the core of motor and fan sizing is the issue of rpm's vs. torque. RPM's are relative to the Kv rating which is relative to the voltage used. Torque is relative to the fan size vs. the rpms' it can take.
In general the smaller the fan the higher the Kv rating of the motor the less torque required. The larger the fan the lower the Kv rating and the higher the voltage required.
I am using a 2100KV motor with a 22 volt battery on my 70mm fans. An 14 to 18 volt system
Great value. The EPO is very good, soft and not brittle, but the paint could be more uniform. Fairly straight forward build for builders who have done it before. I inserted 2x15cm carbon rods in while joining the wings. HK2839 motor, Plush 60A ESC and HK70mm EDF along with 4 metal gear servos. I also replaced the landing gear with the "Landing Gear Set - Shock Absorbing" - a smart move in hindsight. Flying of a paved surface, I first tried to fly with 2x3200mah 2S LIPOs in parallel(400gr weight) but as soon as it rose, it was evident that it was very very nose heavy. Experimented with a 2200mah 5S setup(360gr) and it flew much better but still nose heavy. I am settling for a 3000mah 4S (300gr) setup with CoG of around 10cm from the LE of the wing at its root.
Very forgiving plane to fly, no tip stall and can fly very slowly. Need to carefully setup the surface throws and add some expo(30) for the ailerons and nose gear steering until one gets used to it.

Hi,
Plane looks cool painted, but foam seems a bit fragile to me. Have put some blank waterproof coating on top. Manual is poor: - How should the sticking be done ?? Aileron and tail are together on one servo per site. Which holes to use on the servo ?? Should the directions of aileron and tail (height) be the same ?? - CG not mentioned ?? (ok, will take 10cm) Used 70 mm EDF HK 3300 kV instead of supplied edf and on 4 cell 2350 mA and measured 60A (esc is turnigy sentry 60) Need to balance EDF.... To bad that shipment costs almost equal plane price...

Great plane for value, setup pusher turnigy 2836 3200kv, apc 4.1 x 4.1, 4s 2200 20c lipo. Fly like rocket. very fast. very stable, easy hand launch. very happy with plane and setup.

great base to build a semi-scale edf jet. forget the base setup - it is useless.
split control to 4 servos - 2 for elevator and 2 for aileron - so you can mix up
any combination. adding rudder is a good idea - works very well. put rudderservo direct into side stabilisator. placing aileron servos into wing for direct linkage will be better, original linkage is a little weak, but works also fine.
cutting away moulded wingtip-rockets will add 2cm wingspan; build and add your own wingtip-rails and rockets ...
use a wemo-mini / het 2w-18 4s based setup and you will be pleased! great turbine-like sound and a t/w ration over 1:1 will give you the ability of vertical speedup. topspeed over 150km/h but also the thrust needed for crazy vector-like aerobatics. set the cg following the 1/3 rule will be a good choose
(1/3 of wing at base from leading edge). got 745gr with this 5servo wemo/het
setup without akku. using 4s 2200 will keep weight less then 1kg and give cg
without adding weight anywhere.
adding tanks and rockets underwing give great scale look for display flight,
without for highspeed fun.

We used these EPO platforms to test different engines, With a weak battery and the HET fan coupled to the ARC 28-48-1 with hit 113 MPh on the datalogger . With Nano 65C 2250 battery it goes even faster!Surprising stable with the ailerons linked to the elevator . Poor video on Youtube but you can see the speed! http://youtu.be/yt6FB4HUxkM Great value for a foam kit.
