Kevin, I am familiar with electric motor calculation programs: http://brantuas.com/ezcalc/dma1.asp Is there a heli-blade program? That would be awesome and...
... With a powered prop, the blade design on these ag's are NOT what you'd want for a ff hd rocket design. Most of the autogyro blades of late are designed...
I am very familiar with autogyro blades. Below is a video link to one I designed about six years ago. Although the blades could be used they have no twist in...
... Right. A few ways to look at this and probably a few in between. Either more >3 smaller blades (and look for higher rpms), fewer (3)bladed models (look...
Actually, that is possible but it would require a lot of "hardware to make the arms. Dave Fitch ********************* In a message dated 12/3/2009 2:29:19 P.M....
John, Bullseye . . . You hit the nail on the head. Personally, I prefer the fine adjustability and being able to lock in adjustments rigidly, Dave Fitch ...
John Wouldn't it be intresting if you made a combination of the two. This way you can dial it in and still have some freedom with the launches. Sent from my...
I need to build a tower but I'm not convinced which type might be best I would like feed back from people who have used both types of towers. I am sure there...
I am actually thinking about doing a two blade version. The large twist of my blades -25 degree at the root and +2 degree at the tips makes for a really...
Bob, It really doesn't matter; 2 vs. 3. Actually a 2 blade of the same material and span would come up to speed faster than a 3 blade and therefore reach...
Hello John, Lift is proportional to the number of blades; and so is drag and weight. The more blades, the greater the lift but there is also more drag created...
... I would think that 2 blade rotors might have stability problems, particularly coming up to speed. More than 3 blades is a losing proposition. According to...
How they're rigged probably makes a big difference too. I fiddled around with Venus (Petrovich's) Pancakes a few years ago. Nifty little 2-blade design, but...
It appears most of the US helicopter designs I've seen have 3 blades with the Europeans going with even more blades. What are the pros and cons of only using...
Bob and Dave, Thanks for the information. I new it was going to be stupidly simply. I hope someone else takes a look at this big plastic bag since it's huge...
John, The term "mil" is 1 / 1000 of an inch . . . 1 mil = .001" 1/2 mil = .00050" 1/4 mil = .00025" Dave Fitch *********************************************** ...
DO NOT REPLY TO THIS MESSAGE! I'm compiling a list of c'Roc members, by state, who want to help NAR competitors (especially newbies) in their area. I'll build,...
I picked up our real Chritmas tree a few days ago at The Home Depot and next to the check out counter were packages containing "Christmas Tree Removal Bag and...
Please direct your replies directly to Lee, just on the off chance that our 400+ members do not wish to watch each individual record on this list get built,...
If you would like to volunteer to be on a list of contacts to help local competitors, please send me an email. I'll build, publish, and maintain a list. Joe...
I'm stuck on a slow internet connection, so I can't really check the Fox steam to see what it is, but NASA TV is likely to be better for shuttle coverage. ...
