IS it possible to use 25amp speed controller instead?
 AlbEagle007 542 points
Depends what motor you are using. If you are using D2822/14 than 25 Amper is fine. Even 20 A is ok.

Hi Muhd, The only downside to using a larger than necessary ESC is the added weight. You won't draw any additional current than what the motor is rated for so it won't hurt the motor or the ESC. My general rule-of-thumb is to use a ESC that's rated 20% higher than the max motor current rating to ensure a bit of safety margin. For example, If the motor has a max current rating of 15A, you would want to use at least a 18A ESC to avoid possible ESC problems during long full throttle periods. Hope this helps you make your decision. Cheers, EA!

ok need help with my setup connect all the servos to receiver but have no left aileron movement tried changing the placement with no affect tried different receiver no change servo works fine help
 AlbEagle007 542 points
Try another servo, or maybe it is radio's fault.

This EPP is kind of uncharted teritory for me as a newbie so my question is if regually thin CA is ok ?
 AlbEagle007 542 points
I have used regularly thin CA on this with activator and it works fine.
 tjolle62 2 points
Regular thin CA & activator it is then ! That i have plenty of , Thank you.
 AlbEagle007 542 points
I have glued the elevator and rudder servo with hot glue gun but it is to hot, it melts the epp, so for the aileron servos I used only CA & Activator. Also I put a carbon rod on top of the hole for batery to make it stronger because if it brakes then the battery will fall down and you can imagine what will happen.

Thank's for the info about reinforcment , i have a nice collection of carbon fiber in rods , tubes , flats square in a varity of sizes and shapes so i will follow your recommendation with the battery issue.

Like it! But using the 2822 and Zippy3S1000 this EPP must get alot faster, so not recommended configuration for beginners. Make it lighter if you can. Flying with a 2200 s3 would be very fast. I didn't quite pull it out of a 20ft no throttle dive and kind of blew the front end open.

Anyone know the Reaktor prop saver size? I've never had to reorder one before. I've used rubber bands but would like to get the right thing Thanks Jason
 AlbEagle007 542 points
Hi Jason, depends what motor you have, If you have the D2822/14 as suggested than the size of the shaft is 3.17 mm.

Great flying little airplane. The thicker foam and carbon fiber keep the plane stiff enough not to twist the tail in mid-air as a lot of these little flat epp planes do. With a Turnigy AE-20 ESC, C20 2050kv motor, 9x6 EP prop, OrangeRC 6 chan reciever, 4 Hextronix HXT500 servos, a Nano-Tech 460ma battery and no landing gear mine is 300 grams and will hover at 1/2 throttle. I initially flew it with out the 'winglet' (yep, that's what they call it in the instructions) on the turtle deck and it flew very well, but wouldn't do an inverted flat spin. Adding the winglet made the plane pull one with ease, as well as knife edge effortlessly. The plane is very responsive to the control surfaces and a true joy to fly. Instructions were clear and build time was just over 4 hours. NOTE: The rudder and elevator use a string pull-pull setup, they send you some silky, lightweight cotton string. Frustrating to build and very cheesy. I used 2mm carbon fiber and some wire from the hobby shop to make push rods on mine. By placing the ESC all the way forward and looping the motor wires out of the way, I was able to slip the reciever into the pre-cut slot, place the battery into it's pre-cut slot, and have a perfect CG without the addition of any weight. Using the C20 and AE-20 ESC provides 6-8 min flight times with minimal heat buildup even in aggressive flying (Battery slightly warm but it's nested in the foam so that's not unexpected). The thick foam is very durable, I haven't crash tested min

This planes a 2cells li-po and you better use a 800mah battery, as for the motor the best one you could use is the HobbyKing 2612 Brushless Outrunner 1900KV(as suggested) and as for the ESC the TURNIGY Plush 10amp and 4 htx 500
it is my configuration and it is perfect :)

Fantastic plane!!! Just finished the build and will fly tomorrow if the wind cooperates. Overall, this has been the best quality foamie I've come across in terms of design, fit, and finish. Every part was straight and fit like a glove. I have several of the Red Eagle foam planes and none of them compare in terms of stiffness and straightness of the individual parts or finished plane. The only complaint I have is the way the landing gear is attached. Flimsy little ply plates came loose the first time I flexed the the landing gear. I replaced them with 25mm x 35mm ply plates epoxied on and the landing gear is plenty strong. The recommended motor (HK2612) has plenty of power with 3S batts. Using a Rhino 610mah 3S, the plane weighs exactly 300g and literally leaps vertically with this motor/battery combo on a 8x4 prop. I file a flight evaluation later. Thanks HK for another great plane! Cheers!

Okay, here's the flight report I promised. No wind and perfect flying conditions ... I'M IN LOVE WITH THIS PLANE!!! Trimmed out with just a few clicks of Elev/Aileron and flew like it was on rails. Very stiff with no noticeable flex at all. Hovers with almost no inputs, will turn 180 within a 1 metre space, flies same inverted as upright. Would do every 3D trick in the book if I knew how, yet it's just as happy to fly general pattern style. No tip stall at high or low speed. Landings can be as slow as you like, as it just settles down flat when air speed gets too low. Hand launches straight and true with no torque roll. When word gets out about what a bargain this plane is, HK won't be able to order enough stock. Cheers!

A quick final note on some minor tweaks to my Reaktor. The little winglet on top is flimsy and flutters at high speed, so I added a 100mm long piece of .5mmx3mm CF strip to the top. Very stiff now and seems to improve the handling, especially when inverted. I've been switching between 3S Rhino 610mah and 750mah batts to see which weight/CG works best. The 750mah battery gives nice long flight times and perfect CG balance. AUW is 315g, but the plane still floats down to a crawl without losing lift and the extra power means awesome 3D capability. Cheers!
