Why the cheapest shipping cost are 35 euro to Greece? for a plane under 1000gr weight. While other planes weight more than 1000gr and shiping cost are 25 euros. i don't understand that.

Did you order a battery? Order in the EU warehouse and the shipping and transport time will be lower.

ElectricAussie. Very interested in your Reaktorette - looks like great fun! Can you give some specifices on the alterations. I can see the trimming of the wings and elevater/rudder. But did you move wing back or cut some out between wing and rear and then reattach? I can also see you removed sides of fuse and trimmed down the top of fuse. Appreciate any comments.

Hi Stanley, There was no grand design plan involved in building the Reaktorette. I had the carcasses of 2 old Reaktors up on the shelf and just decided to butcher them into something smaller that would make use of the fuselage parts that weren't damaged. I cut the nose off of a fuselage and cut a new wing opening. I then cut the outer ends off of a wing to get it down to scale with the smaller fuselage. Used a straightedge along the horizontal stab surface to set the wing incidence. The rest was just making it up as I went along. I had a new C20 motor in the spares box and some small 2S lipos, so it fell together pretty quickly. Surprised it flew so well. I could fly it inside a shoebox if it were any smaller. Cheers, EA!

Thank you EA. Sorry it took so long for thanks, but got ill.

Anyone had problems with the aileron foam hinges, mine look just about non existent, new out box, very little foam holding them on, full of holes, it's like they removed to much foam and only just hanging on by paper thin foam or less. Anyone got any suggestions on how to fix this thanks

Hi Paul, There's pros and cons for the hinge design. The pros are mainly the lack of hinge gap (air leak between upper/lower surfaces) gives better flying characteristics. The cons .... you get about 10-12 flying sessions in before cracks/separations start appearing, usually at the outer ends where the ailerons take the most abuse from rough landings, tumbles, etc. I've built 5 Reaktors (wear out one every 6 months or so) and no longer wait for the hinge cracks to appear. I epoxy or CA 3 short strips (outer end, center, inner end) of tough cloth (fiberglass, nylon, etc.) across the hinge line on each wing half. Lasts the whole life of the plane and is still in place when it's time to bin the plane and build a new one. Cheers, EA!

Thanks electric as you said I might do it from the start put some hinges on

Blenderm tape works really well. Just a strip on top of the hinge. Alot of foamies use only blenderm tape.

A thin layer of "WELDER" glue over the hinge thin spots 1/2" wide will help it stay together.

Looks like they don't sell the D2822/14 motor here anymore. Any other recommendations for a motor? I hate it when they sell a plane and don't even offer a motor in the related items area.
 ElectricAussie 4350 points
Hi Wheelnut, By "don't sell here" do you mean the US or international warehouse? The D2822/14 is available in both (I just checked), but there's been some changes in the US and it's sold thru what is being called the US Western warehouse. Search PRODUCT ID: D2822-141450 and you'll find it. Cheers, EA!

I've run a E-Max 2822-1200kv for over a year. Works great. $8 at Value Hobby.

I have used the HK Donkey motor and 10 Amp ESC combo, 440g of thrust. The plane should be less than 340g with proper size LIPO battery. Check the FILES area for more info and ideas on upgrades. There is also a Thread on RCGroups**** under EPP Reaktor.

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

built mine yesterday and flew today. I went w hextronic 9g servos, 18A turnigy ESC and 1000Mah packs. Weighs in at 312g. Unless you plan to fly indoor, dont bother w the landing gear. I went w the suggested motor. I should have picked a slightly larger one since hovers can be done but with patience. I put my CG 10-15 mm FURTHER back than the instructions ask... Flies a dream. I am VERY VERY pleased with this model. Its a sure bet!! GET IT, DONT THINK TWICE ABOUT IT!!!

This would have to be the best value for money item that HK provide. I have had hours of fun flying mine (outdoors) using the recommended motor and battery size (2S).

When the Reaktor was unavailable and on back order I acquired a TechOne Tempo 3D mini (its equivalent) for a lot more outlay and equipped it with an Eflite Park 370 and 3S 850mA for more punch and haven't regretted it.

For outdoors flying I would recommend fitting a 250 Watt motor on 3S 700Ma - 1000mA still use the 8 x 4 SF prop.

All I want now is for HK to bring out the equivalent to TechOne's Tempo 3D (1000mm span) ie: a bigger version of the Reaktor.

If you really want a low cost fun plane to fly that you can practise your aerobatic skills upon get the Reaktor.
