Or you can do it yourself by using this website. By the way how did you determine where the location of the CG should be? Dan.

Hi Dan,
The CG was marked on the plan. The wing area was also given, but I enlarged the plan to make the size that I wanted. In calculating the area with the formula on the website you gave me, I come up with 1340 sq. inches. Maybe you could cross check me? The dimensions for one wing panel are: span=40", root=23.5", tip=10", now both the LE and TE taper, so if I align the TE on a straight edge and measure how much less the LE is at the tip. I get 12". Thanks for the help! Bob

I also get 1340. With a weight of 22.2 pounds your wing loading is 38.19 ounces per square foot which is very good for a pane this size. It will go up as you complete the model but anything around 40 ounces is great. Using the numbers you have posted and the below website, I get a CG location of 9.61 inches behind the leading edge at the root. with it placed at 25 percent of the Mean Aerodynamic Chord. How does this agree with the location on the plan? Dan.

HI Everyone!
Well there's nothing left to do!! I even brought her downstairs to my second airplane room! I've put the Gee Bee back on the table to finish it. Ok i guess we'll talk about the finished numbers that Dan has been helping me with. I'll be using two batteries at 8.8 oz. apiece, and a pilot bust, i'll guess he'll be around 2 oz.. that's all that should be added to the first 22.2 lb weight. That'll bring the weight up to 23.6 lbs. i'm rounding the decimals to the next higher number. I think that will still be in an acceptable wing loading number range. Now what worries me a bit is that Dan calculated a CG location of 9.6" behind the LE at the root, and my plan is showing a measurement closer to 6 3/4" back from the LE. Hmmm... I'm going to go back right now and check that number! Hope you All have a Great weekend! Bob

DEFINETLY and I mean DEFINETLY stick with the CG on the plans. It looks like the leading edge sweep back of 12 inches is off quite a bit. It's probably closer to six or less. Has the prototype of the model you are making flown before? Is it modeled after the short wing version or the long wing? Dan.

Using this website and changing the 12 inch sweep back to six instead of 12 I get seven inches which is just right. Dan.

Hi!
Thanks Dan, I checked the way that I figured that sweep back. I did it incorrectly.. It is around 6", so I'll stick with the 6 3/4" that's shown on the plan. I really appreciate your input and help! Have a Great night everyone! Bob

Hey Bob I found a set of plans and a companion article on AeroFred are these the plans you started with? The plans were designed by and the the article authored Col. John A. DeVries USAF (Ret.)

Add the root and tip chords and multiply by 1/2 span. If the tips are round (I think) don't include them in the 1/2 span but figure the area of the circle(of the two tips together and add it in Circle area is Area=Pi times the radius squared

Hello!
Yes, Mike those are the plans that I used... I took them off of a plans site called "Outer Zone", then had my stepson enlarge them on our shop printer. I was able to get everything, except the wing, so many times, I was here, at my desktop, measuring right off of the 19" screen in front of me! I couldn't find the article that you were talking about though. I'd like to read that. Well today, my pilot came, I did some surgery, installed him, and finished the canopy. He looks a little like Clark Gable, but when I put this leather cap, and flying goggles on....well I'll just pretend it's HH! I stuck the cigarette in his mouth just to complete the picture. So now it's just a wait for the receiver, which my buddy at Hobbytown can't tell me when will be here. I've noticed that many supply websites that deal in JR products, are out of everything. I went to Horizon to find some extensions, and they had nothing, as a matter of fact they had very little in the way of JR accessories. It says everything is back ordered, date, TBA. Does anyone know what's going on? Ok... here's a couple of pictures of HH! Have a good night, Bob

Okay, okay, this is nit-piking, I know but...HH didn't smoke and filtered cigarettes weren't common until the early 50s. Of course Howard would have been able to afford filters even though they were rare and expensive. But, it does add to the pilot's devil-may-care character that would have been necessary to maiden the real H-1. Smoke 'em if ya got 'em, Howard.

The cockpit is looking good Bob. Thanks for sharing, again.

Horizon no longer is the JR distributor Look for JR Americas and you'll find it.

Bob, contact Ray Thompson (he does a lot of R/C Swap meets) he goes by Big Dog R/C Parts. I buy his stuff he uses uses two different heavy duty wires and if he doesn't have the length you need he'll make it. His prices are very reasonable I came home from the last swap meet he was at with a bag full of extensions, connection clips and Y cables and only spent about $20 to $25. He is located in Mansfield, TX. bigdogr(at sign) sbcglobal.net 817-453-8110.

Tom, I'm sure Howard was a filterless smoker, the man bought his suits off the rack at Sears and JC Penney!

Their is a story that HH never carried any cash on him, one day he was at a TWA terminal and needed to go to the John and didn't have a dime to open the stall door. Howard had to crawl under the door to use the toilet! The next day he had all pay toilets removed from TWA facilities.

Hey Everyone!
Thanks for the help Doc, Mike. I went to JR America, and they told me that the 11 channel, dual battery receiver I was looking for has been discontinued! What a bummer. I already paid for it through my Hobbytown dealer, who only gets JR products through Horizon, now I have to ask him for my $ back, so that I can find a different receiver and dealer. I use HV servos on all my planes, so now I'm going to have to adopt into this new XBus system that JR offers. I know it's probably an efficient, better way to set up larger planes it just much more expensive. I don't mind spending money to do things right, but I've never had any problems with the way I've always done it. The Xbus system employs a central "hub" in which your receiver(s) and battery(s) plug into, then multiple end leads come out of it, to your servos. You also need a programmer. My $200, 11 ch reciever just jumped to over $400 for this system. I just wish they'd make it a choice, not something that I am now forced to do. Today, when I was just about to pull the trigger and order this new thing, I was informed by JR America that the wiring that I'd need was out of stock, and would be back ordered for 3 to 4 weeks. Alright, alright enough cryin'!, I did go to my field today, it was 85 degrees out with no wind!, and flew the Habu turbine for a perfect flight! so that was good! Mike, that's a great story about HH crawling under the stall door! , and I am going to paint that filter white! Thanks for Listening, Everyone, Bob

Sorry to hear about all your radio issues. Picking a radio brand can be a bit of a crap shoot at times.

Hey Everyone!
I'm still waiting for JR parts, and I had to reconfigure the radio system due to the fact that they've discontinued the 11 ch I was going to use. It's very close now, I'm thinking in the next couple of weeks we should see a successful maiden! I'll surely video it and post! Thanks for the support! Bob

Bob, how about a few images of your radio installation while we're in a lull. Dan.
