I posted a while ago about this team in France building a flying replica of the Mosquito. Didn't realise how advanced they have got. Check out the engine runs and taxi tests!!!!!

Its a pity it suffers the same problem that many scale replicas have, that the Cockpit enclosure looks badly out of scale. overall, looks OK though. I'm puzzled about what they were trying to acheive with the taxi runs. Short bursts of power and suddenly closing the throttles, with the tail firmly held down - its no wonder it was a bit wayward directionally. They had plenty of runway... I wonder what the plan was?

I'd like to know how they are cooling the engines as the only intake seems to be under the engine (Carb intake on the real one)

The smallish cutouts behind the props are possibly enough , although I'd have thought these would be covered by a spinner a some stage , but possibly not . I have seem some RC planes with engine heating issues , and often its not getting the air in thats the problem ( even a small opening passes a lot of air when flying ) , but its getting the air back out . You need a bigger hole behind the engine , than at the front . |

I'd like to know how they are cooling the engines as the only intake seems to be under the engine (Carb intake on the real one) I see the replica has the same cooling air intakes in the leading edges of the wing roots as did the original Mossie. I do not know what engines are installed in this little machine but if they are Rotax 912s then they will have liquid cooled cylinder heads which would help. As for the taxiing trials, I guess it pays to have directional control on the ground and effectiveness of the brakes etc all sussed out before venturing down the runway in earnest for the first time. Edited to add: Here is another video showing the assembly of the Mosquito junior at an airfield. At about 5 and 6 minutes in you can get a good look at the leading edge air intakes which seem like the real thing rather than dummies for appearance sake. A very impressive project. |

Thats pretty impressive. It sounds pretty good too, considering the lack of a merlin. After a quick jaunt down to Tyabb to look at the scale Mustangs the subject of gearboxes cropped up, I was wondering if there are V6/V8 engines purpose built for aircraft that could be used?

The engines are air cooled " Flat 6 's " . Not sure what brand , but they look like something you might find in a Fletcher , and dont appear to have any form of water cooling . Thats what the humps in the engine cowlings are ( where the exaust stubs on a real mosquito would be ) . Its clearance for the cylinder heads , and the exaust stubs hang down from there . ( At least thats how it looks to me from some pictures I,ve seen ).  |
