I thought about writing a short construction report about this MULTIPLEX plane for a long time and finally decided to do so. Because the new GP-14 VELO by MULTIPLEX is significantly better than its reputation. In a german forum the aircraft and the construction are being trashed, which I personally cannot understand. I built the plane and I`m absolutely convinced by the quality and the flight performance. I think the development team at MPX did a great job with this model, and that’s why I’m sharing a few pictures of the building and nice flights in the mountains.
First of all, it is very commendable that there is a detailed, illustrated instruction manual available for the GP-14, which is a rarity these days. Various installation options are described, whether landing gear, FES or retract EDF, all information can be found in the instructions. The cockpit tub including panel is available as an option from Multiplex. Also a special carbon spinner and a white painted carbon prop is available. For this prop, the hacker service recommended a suitable engine for 6S setup, the A50-16S.
For the linkages in the wing, I didn’t use the standard linkages with Z-wire and fork head, but rather the extremely high-quality installation frames including rudder horns and pushrods from heizkoffer.de. It couldn’t be more playful, rigid and elegant!I still had a pilot in 1:3.5 from Tailored Pilots which fits perfectly into the GP-14 VELO. I drew the rudder pedals in CAD and simply printed them out of PLA and painted them. Thae same I did with the linkage and control horn covers on the wings, they are also printed from white PLA.The 5000 battery is located directly in front of the wing joiner and with the pilot in the cockpit, not a gram of ballast is necessary in the nose for the correct CG!The finish is entirely realized with plotted vinyl stickers.
The power unit by Hacker allows very easy hand launchs and in headwinds, two steps for takeoff were enough. The A50 offers enough power to climb a good 45° with a current consumption of approx. 70A. So with the 5000mAh battery allows 6-7 climbs per flight.
The GP-14 performs fantastically both in thermals and in aerobatics and the pulling power is also very good for a model of this weight and size. With the help of the ACL glider lights on the bottom of the wing, the model can be perfectly recognized or found even at high altitudes or when flying on a slope with a changing background.
All I can say about the GP-14 is: Well done MPX!
Hallo Robin.
Sehr schöner Baubericht, auch dein Kommentar zum
Forumsbashing gefällt mir.
Fliege selbst eine GP 14, mit Jetec 90.
Fliege das Teil extrem gerne, ist ein geiler Flieger, mit super
Durchzug (8,2 kg). Ablasser aus 400 mtr. sind kein Problem.
Ich bin auch sehr zufrieden.
Grüßle

Hallo Robin,
auch mir gefällt dein Baubericht sehr gut. Besonders deine Fotos sind prima und werden mir beim Zusammenbau meiner GP14 Velo (Standard) helfen. Tolle Luftaufnahmen mit den Bergen im Hintergrund.
Ich fliege viel am Hang beim MFSC Ludwigsstadt aber auch in der Ebene, auf dem Flugplatz des MMFG Mallertshofen / Unterschleißheim. Ein Handstart der GP14 sollte, auch ohne Gegenwind, in der Ebene möglich sein und da bin ich noch auf der Suche nach einem geeigneten Antrieb. Du schreibst in deinem Bericht, dass der Handstart mit dem Hacker A50-16S und der Klappluftschraube 18×8,5 problemlos ist.
Ich hatte an eine größere Luftschraube GM 20 x 13 gedacht und als Motor den Peggy Pepper 3226 -1600KV mit Super Chief 6:1 von Reisenauer, um beim Start sofort einen kräftigen Grip zu haben.
Mich würde deine Meinung dazu interessieren?
Viele Fliegergrüße,
Jürgen
