Polish or Not?

Thanks all.

Udi......

No gas....295lbs.

Gas @ 8.3 gal=50lbs

Me= 218lbs

total bird, me, and a full tank=563lbs

I figure @ 22 foot rotor system A=379.94 which is 1.48lbs per square inch.

I figure @ 24 foot rotor system A=452.16 which is 1.25lbs per square inch.

To me when I first flew the 22s I felt like I was gonna fall out of the sky with every turn, but I was also flying way behind the power curve.

Now that I've learned alittle about flying mine, the 24s feel great! Even a little floaty on landings.

If you feel the 23 DW are the ticket, I'm in! I do worry about ground strike with the 24s when spinning the blades to balance and tail first, super slow landings.

John,

Here is the calculation for Da Screw, fitted with a pair of 23 DWs, flying at a DA of 1000 ft (calc courtesy CB). The numbers look really good, but you should really get Ernie's blessing before buying.

Udy, The machine Ron was flying was totally different than what John is flying. John, in my opion, will need longer blades due to the lack of thrust. Flyem, then buyem!

Mr. Mike Boyette,

Could you run these wieghts and measure by your Dad and see what he says please? Don't know to go with 23s or 24s. Thanks in advance.

John,
I spoke to him earlier in the week he said he wouldn't go any bigger than 23' disk on a VW powered KB2. I Hope this helps. I think if you went to a 24' disk you would have ground clearence problems. I maybe wrong. When I see hime tommarow I will ask him again. He does visit this forum, however he usually only reads posts. He leaves it up to me to post.

John, just a minor (well, maybe not so minor!) point, gas weighs pretty close to 6.5 lb/gal. Water is what weighs 8.3 lb/gal.

[GyroRon]

Udi, John IS a lot fatter than me. I lost 3 pounds this week and still pushing 203. John has about 15-20 pounds on me.

[Screw]

Dean,

8.3 gal is the size of my tank. I figured 6lbs per gal. 50lbs because 6x8.3=49.8lbs.

Ron,

You wouldn't wiegh 203 on the moon!

Mike,

How much would Dad come off a set of 23s taking on trade-in for my Brock Blades 2 foot hub bar (22ft) and blade box?

John ;D

[Chuck Irby]

Good one, John!

[MikeBoyette]

John,
No trade ins. I posted the price list earlier. You can save yourself shipping if you pick them up at BD.

[GyroRon]

John my scale is expensive and digital - and tells me my body fat percentage as well. 203 baby! It is okay to be upset, I will comfort you over a round of McDonalds double cheeseburgers at Roc....

[Screw]

Mike,

I new the answer...I was trying to be cute.

Ron,

Your on! I'm a sucker for MD double cheeseburgers. How did you lose the wieght? Dr. Phill's new book?

John ;D

I call it the "Working the weedwacker" diet plan. I am back to work, back to walking my Arse off all over peoples lawns with the weedwacker and blowers and fertilizer spreaders etc.... - I get to sit on my mower so I do get a break! -

Winter time is hard on my body with nothing much physical to do. Once I start working I can lose weight fast. I plan - yeah right you say.... - to stop smoking, and cut back on the portions of food I eat and maybe even exercise a little this summer. This beer belly I got is embarassing

[Caribean_gyro]

thats the reason I got 180hp. my pasengers alway tell me I shouldlose weight to carry bigger people but I told them. Iam the owner you want to fly build one.

I am slowly working it out any way.

Question the rotro hawk blades that is mentioned in the thread. are they the new version or old version. I have flow the old one not the new one nor Ernie's blades. But I have 2 guys here that said they leike the new version (I think they are fleck) But thenm I have a guy with an aircomand and he likes the Dragonwind.

I just want to understand more the Naca Foil issues as explained by CB on a precios dicusion plus I am been ask for advice and want to give a honest opinion.
