Hi

I flew my Savoia marchetti sm79 for the first time yesterday . It's 1:5.3 scale,(13 foot, 33kg, 3 zenoah 38s) I started building it at the beginning of April this year and the airframe was completed at the end of June.
It's a two piece wing and a fuselage with a removable tail.
She flew well, she's a little tail heavy however this is being addressed.

Below is a you tube link to its first two flights, please take a look.

That my boy is your best one yet!!! Brilliant creation

Ian.

Vary good.

Bonzey

Real nice I enjoyed watching that, well done.

Thanks for your comments , much appreciated.

I'm now struggling with my next project, think it's going to be a dornier 335, there's unfinished business with this model.
This version will be smaller than my last attempt at 1:4.5 scale, with a one piece fuselage and wing ,powered by z62s with reduction drives. I've already had a 140cm prop shaft machined so I'll be able to place the rear engine over the c of g. As always though the sticking point are the retracts, they're long and the nose leg goes through 120%. Century jets do a set, though they're not responding to my emails. Anybody with some unwanted large retracts please get in touch.

So we will see this one flying on YouTube. Next week then Karl?

Bonzey

No , give me at least two weeks , I've got to finish decorating the house before I start on it.

Karl

Lo,

Karl,
Well done looks and sounds great I never thought that zen 38s could sound that good ? how are my servos doing ?
cheers Euan.

Thanks Euan,Your servos are working well in the Savoia.
Hope you were happy with the glider.

Karl, the Lunak is nearly finished just waiting for a conformal tank to be made so I can use a P20 turbine on it ,
cheers Euan.

Hi Karl love the Marchetti - can you give some more info - weight , engines used etc,flies brilliantly - give the video master a raise - he,s getting really good

Hi Pete
The marchetti is 13 foot span blown up 13% bigger than the normal Don Smith plan.The most difficult part was building the fuselage as I had to design formers for the rear fus. It's a two piece wing and the fuselage has a removable tail. It's powered by three zenoah 38s, weighing 33 kg it flys on tickover. The undercarriage are unitracts Lancaster units that fit perfectly. I've added a little extra weight to the nose as it was sensitive on the elevater. I'm keen to get her flying again it's just difficult juggling work/weather getting vodders there to be a witness.
Yes the camera work is getting better.
Started on the next project already a 1:4.5 do335.

Hi Karl,

Thanks for the info - really flies well at that weight.good luck with the Do 335 I seem to remember that one!
If you want some inspiration have a look at Carl Bachuber's website,just Google his name.Especially the six engined pusher prop B36 - how unusual can you get.

Cheers
