Head Servos arrived

After installing and checking RC I checked my hang angle and oops 20 degrees!!!

Had to install lead to the Tail to get an hang angle of 16 degrees with all necessary on board.

Complete Weight is 811g (1,79lbs).

So IŽll try the first fly soon, if the weather, especially winds calm down.

But thereŽs one Question left!!!

The plan mentions that the Fire Fly Rotor Head needs a LEFT Trim of around 2 degrees for level flight???

Looking from behind the mast, we got an anticlockwise rotating Rotor, which got the blades on the right side going forward into airstream, so that the right side of the rotor will cause more lift and as result the model will turn LEFT.
So if I add additional LEFT Trim IŽll force the model more to the left than it already will, or am I thinking wrong???

Thanks for help!

Hi Maakus

The instructions are correct, there will be a need for a bit of left trim, this is usual.

Cheers
Rich

Have fun Maakus,

Just try small short hops to trim, let it take off when it's ready try not to force things.

Thanks Rich!!!

Today it wasnŽt possible to try the first hops, because of rain, rain, rain...

Hope tomorrow will be better!

Fire Fly III is almost completed to use up some offcuts just created from a fixed wing build (shame on you Rich)

Stringers added and dummy ribs to the tail surfaces, this is something we talked about doing last time we all met up at Old Warden and has seemed to work out pretty well.
Have also been playing with depron and rubbish and made a very rough 9 cylinder radial with a 5 and 7 cylinder versions in bits. A bit of a practice for the profile kellett.

Regards

Rich

Chris,
Yes it took a while to construct but it keeps the grey matter active, nearly ready to test fly it. I have carved up some foam feet, just need to add the electrics and it's ready to go.

Regards

Oorah! Bill. I'm so glad you got out with your FF. The fact that you had a great flight is just icing on the cake. Makes me smile ear to ear. FF the camera as long as you had fun.

Fantastic Firefly, I like the machined head and of course the radial engine. It would look the business in say a magazine article for example I'm sure your next flight will be a success.
