Control surfaces integral to servo arm

Jan 28, 2007 18 Replies

Hi,



Please read the date below when I first posted this idea in 2006. And if you searched my profile, you'd find the other people's responses.



Also if you have the Feb. 2007 issue of Model Aviation, you will find on page 14 the system offered by John Durant on a no linkage servo. Please read the article to learn about this idea further.



Sort of justifies my "crazy idea" don't you think?

How about servos that are configured to fit the trailing edges of wings, stabilizers, and vertical fins? That way, the servo arms become part of the flying surfaces.

Servos may be built large or small, but with this idea, the servo to moving part linkage would be eliminated, and movements become more accurate.



Of course you may see problems for balancing, but with the design of the plane made to allow for the so placed servos...



Please chew on this for awhile : ) See any problems?

Geez, so many problems where to start. Just try to imagine how many different sizes of servo would be required to suit a large range of applications, and then consider the manufacturing implications, this alone should be enough for you to realise what a impractical idea it is.

If you read the article in Model Aviation, current issue page 14, I believe the problems you are concerned about have been solved. Please let me quote in part, that article "John proved the concept through the most demanding flying he could find: Giant Scale, Unlimited-class IMAC (International Miniature Aerobatic Club). Four years and several thousand flights later, not a single Direct Drive failure has occurred".

I am not a representative of the company, nor trying to make a commercial. Just want to vindicate my idea that I mentioned in the earlier part of this posting.

Furthermore, John DuRant offers custom made cases at no charge. Can't ask for better than that, can you?

I saw that in MA and thought of that thread but I fly smaller planes and would have to REALLY study it before trying it. mk

I am back. A curious friend just called up and said he logged onto the site given in the article (MA page 14) and found some photos.The photos show that your preferred servo is housed in a housing made by that company. The system is almost like my invisioned setup over a year ago.

Honestly, I am not trying to promote the company, but to inform what's out there. If you would like to know more, you have log onto the site youself. When you open the site, you'll find other things in modeling, but click onto "conversions" photo and you will see how it's done.

He he, that company is about an hour from here. mk

I don't get MA. What is the address for that site ?

Thanks

Ken

Ken,

Good to hear from you again. The address is, www.durantdirectdrive,com and I believe you'll find it interesting.

Good flying, Wan

believe you'll find it interesting.

Ken,

The address for the site though appears blue when posted, did not work directly for me. I had to paste it onto the search engine in yahoo, then I found it. Perhaps I should not need to tell you as you are quite savvy.

Take out the "," in front of com and put in ".". ka8jvx

That's an awful lot of words to just say `I told you so!' :)

Didn't want to post again, but what is prat? Wan

Good to hear from you Wan. Haven't see you around for a while. I remember you talking to me about this idea close to a year ago. Went to the site and looked it over , but I still haven't 'chewed' it over enough yet to really comment on it.

Ken

Hi Wan, LOL - Boo got me too. I Googled it and prat = buttocks. Thanks Boo for adding significantly to my vocabulary. Now I may use prathole without seeming vulgar ;-))

Sorry, can't but really LOL at your comment. prathole, huh : )

C'mon Wan , get your head out of your prat lol :-)
