Seahawk Posted January 6, 2009 Posted January 6, 2009 Happy new year to all of you ! Let the new 2009 be full of prosperity ,generous and nice in everyone's ocupation , who deals with our favourite sport -the aeromodellin! Lately i've started a project for the building of a copy of dual motor amphibia MARTIN MARINER PBM 5A in M 1/12 Wingspan: 2850mm Lenght: 1880 mm Engines: 2x20 sm3 RCV-120SP The model is made from extrusion moulded foamed plastics with a GFK covering. I hope That i would take place with it in Nessebar Seaplanes Model Cup 2009 - the only competitiion for models of waterplanes in Bulgaria on 12. and 13.09.2009. http://rc-bulgaria.com/index.php?topic=541.0
Grzesiek Posted January 6, 2009 Posted January 6, 2009 Przepraszam a co to za silniki??To chyba nie sa WANKLA?Przykro mi ale nie znam Angielskiego.
kreis84 Posted January 6, 2009 Posted January 6, 2009 Przepraszam a co to za silniki??To chyba nie sa WANKLA?Przykro mi ale nie znam Angielskiego. Grzesiek asks what are these engines? Are they Wankel engines?

f-150 Posted January 6, 2009 Posted January 6, 2009 Trochę opisu The RCV60-SP RCV90SP and RCV120SP were designed with the scale modeller in mind. This quality CNC machined engine has a similar power output to conventional poppet valve 4-stroke engines and can be used in scale or general sport models. Models that would normally use a 4-stroke .60 or a 2-stroke .40 can use the RCV60SP, models that would normally use a 4-stroke .90 or a 2-stroke .60 can use the RCV90SP and models that would normally use a 4-stroke .120 or a 2-stroke .70 can use the RCV120SP. The engine still uses RCV's unique rotary valve system - which has only one extra moving component to a 2-stroke and so is easy to maintain. One more benefit to RCV SP engines is the behind the prop starting facility (now included with engine), which allows the modeller to stay behind the prop at all times A tu dane techniczne Z opisu jest to czterotakt z wirującym cylindrem,w googlach jest film z pracą tego silnika A tutaj PDF z dokładnymi danymi i przekrojami

mammuth Posted January 6, 2009 Posted January 6, 2009 I belive that many of us will be more than happy to see some more pictures about building fuselage engine mounts etc. So... do not hestitate;)
Major Posted January 6, 2009 Posted January 6, 2009 engine is amazing. That what I want to say about this project.
Seahawk Posted April 7, 2009 Author Posted April 7, 2009 Hi Szymon, Thanks for the interest you are showing !
madrian Posted April 9, 2009 Posted April 9, 2009 Sorry for my English, i never can learn this, but try for many years. :ble: I look photos. Is very nice plane. How big weight you want get on finish? U can show photos inside? Very good work. We waiting for progress and more photos. :wink:
Seahawk Posted April 11, 2009 Author Posted April 11, 2009 Hi everyone , I beg my pardon I write in english .I hope there are no insulted. Reccomended full weight for this model is 9 kg.To my regret i don't have many pictures ,but my goal was to build it ,not to show how it's made step by step.This is probably an oversight and further I'll take more pictures .Inside the ribs are hollow,and the board wall is 30 to 35 mm foam. The glider of the model with the stabilizers ,the centreplane and motogondolas/without engines/ in the moment weighs 2500 g. There will be progress ,but there is still the landing gear to be done and its fitting in the body.This slows the co vering of the body with fiberglass. [
beaver79 Posted April 30, 2009 Posted April 30, 2009 9 kg?? Ok, my idea is to use this great machine to transport Your fine Bulgarian wine to Poland It's Mariner, so we can use one of near lakes ;P. Sorry, but my opinion is, that it will be crime, if we (begginers) won't have photo-story with clear directions how to build plane like this. Off top: how did You get to this forum??? thera are few Germans, as i know, but nobody from Bulgaria, i think... Best Regards
