I've done 4.5 hours total flying now and over Easter i will ( hopefully ) mount my dummy Lewis Machine gun . So I guess that'll be a good reason to do another little vid.Hey Jim.... more vids please.And when you see Kev next tell him I'm still going to finish my pilot cert.Hopefully this year if he will still be teaching.Kev is still teaching , i will let him know your intentions.
Cheers

Thanks Pete , I had found those , my baffling is a mixture of that and cheating some Revmaster methods .I'm going to run it with a water manometer set up to measure the pressure drop between the across the heads etc. and see what i have got .The Baffleing was on the KC Dawn Patrols web site.cheers

Great work Mark , Danny sent me a couple of youtube clips about 'balance beads', used in tyres , to understand how it all works . Amazingly simple once one understands the process.
I don't think it can ever be perfect though, because of the ' hunting ' gearset used in the gearbox . That means any imbalance in the engine will be in a different place at the prop shaft every engine revolution .
I suppose an extra Balancemaster mounted to the engine flywheel may take care of that .

Thanks Pete , the new prop may take a few rpm off it but i would still expect it to be 4K+ . The valve train and reciprocating components will do this easily ,even the inlet port doesn't reach peak velocity till mid 5K with the 458cc cylinders . The biggest challenge is dealing with the lack of cooling fin area.I thought the vw engines were ment to rev lower then that( 3400-3800)?cheers

Hi Pete , the engine is doing 4700 rpm at full power climbing and at 4200 rpm I have about 62 knts in level flight.How many rpm is that engine doing in take off?cheers

Thanks All for those replies and well wishes...most appreciated.
I'm very surprised at how well the Nieuport flies straight out of the box , although I must confess I had the benefit of years of experience and testing the
guys in america have done . So I implemented most of the changes they had discovered and it all seems to tame it nicely.
cheers

Hey Pete , I was hoping no one would notice ! , I'm carving my own prop 80X47,not quite finished yet and was keen to get flying so I just put a Powerfin on .cheersIs that a 3 bladed prop I see?JG

Over 4 long year since I purchased a partially plans built GL 7/8th scale Nieuport 11.
Here is the first day of flying testing at Watts Bridge , QLD
Cheers

The sprag clutch is just for the starter motor , has no effect of the power transmission from the engine to the prop shaft.

This is the most recent Discussion Paper that I have and it is also closed.
So if a weight increase in RAA is a current CASA project , I'm unable to find it .

Yes, the speed is amazing , and explains why the 'Galloping Ghost ' impact, when viewed in normal time , doesn't show the aircraft at all .
