Hello,

My name is Mr. Michael Mccarthy, I have contacted you before without any response from you. Please replied if you receive this message. I have something very important to discuss with you, I have a vital information to give you. Could you please get back to me on (mmichaelmccarthy4@gmail.com ) for full details.

Michael Mccarthy.

Thank you for the information, I am a ways out of needing an engine but want to do some research to find an engine that will work for the 750 and not cost more then the plane.  Any input you have will be appreciated.  I also like your modified wing design and plan to use it on the plane rather than the slats.  Thank you again for your response.

Thanks Ron,
It is challenging to work out how to create the parts. It is quite satisfying when they are done and they match the dimensions of the drawings within a fraction of a millimeter!

Hi Ron,

I checked the photos...Ok for the elevator. I went to the Savannah website and checked their VGs on wings. They are all spaced equally for the entire wing...I guess that if you wanted the wing to stall inboard first you would want to have more VGs (spaced closer) near the wingtip compared to the ones installed near the cabin...

 Since the 701 has washout at the tip and flaps are somewhat down (compared to the ailerons), our wings will always stall from the cabin outward to the tip, we can also use the equal spacing for the wing VGs. The 701 wingtip and aileron should continue to stall last thus retaining full attitude control.

Still pondering... and with the weather being so-so, not yet ready to install.

Hi Ron,

Single, doubles so ...For the placement between 8% to 12% It is fine. For the SPACING it does not add up I will run out of VGs before the whole wing is done.

Still have to check for correct spacing .

I'll let you know.

Hi Ron,

If you were to put 1 Vg every 60mm (6cm) you would need 5 per foot X 12 feet per wing = 60 per wing (120 for 2 wings) !!!

The wing kit only has 46 aluminum VGs... If I wanted to put them at equal distance, I would have to put them 6 inches apart for the whole wing... (23 per wing = 1 every 6 inches)...

I understand that if you wanted the center part of the wing to stall first, you would put the wingtip VGs closer together than the ones near the wing root... But how close and is it needed for our CH701s?

Your thoughts ?

Norm

Hi Ron,

That's where I took the info but the placement is for their PLASTIC VGs and mine are like yours Aluminum...So, I'm still trying to figure out the spacing. The placement on the wing is OK but the different spacing (outboard/inboard) is still being debated...

Any toughts ? Regards,

Norm
