Default What does your Funtana 40 weigh?

Mine weighs 6 lbs. 3 ozs. with a Saito 91 and JR 537 servos throughout. At the moment I have a homemade much larger landing gear made from 1 1/2'' aluminum stock, waiting for the cf gear come available, it weighs about 5 1/2 ozs. by itself, plus 3 1/2'' wheels to deal with our gopher hole laden field. Please note your motor type and size, servos and any changes to original plane.

5lbs even with the .46FX

Switched to .61FX due to fuel problems

5lbs 5oz with .61FX and Macs Muffler.

Switched to 7 fl oz tank so I'm carrying about 3 less ounces of weight and flying at the equivalent of 5lbs 2oz dry

5lb 4 oz

Mini servos all around(hitec 5425's in the tail 225bb's on the wings, HS 81 micro on the throttle, OS 50sx (sx stands for sucks), 720 nimh battery (light).

I am not impressed with the OS 50. I was expecting alot more power then the 46 fx, it was only a slight increase.

It's hard to get any power out of an OS using the stock muffler, they are soooo restrictive.

5 Pounds, 9 ounces, with a Saito 72, SlimLine pitts style exhaust, , Aluminum spinner, remote glow driver, and remote fuel filler.
Using S3004 servos, with CF push rods, and a 1450 mah battery located in a CF rack under the wing hold down brace to off set all the extra metal in the nose. I also added some plywood to triple the thickness the front dowel holes since I noticed some wear on the dowels after engine break in/ run up tests. I hope to maiden the thing this week if I can sneak away.

Well, weighed mine at work this morning and was a bit disappointed but it came out to 5lbs 12oz. Saito .72, APC 14x4W, Hitech 5245MG Digitals, aluminum servo arms, steel pushrods w/ball links on everything, 6 volt 1250 Hydrimax NiMh pack, Hitech Electron 6 receiver, stock gear & wheel pants & tires, Sullivan tail wheel bracket, plastic spinner, cowl on, remote fuel filler, inline filter, wing dowel hole doublers and brass tube over wing dowels.

Pretty much built it per the book and used hardware I had already, have to change to carbon pushrods, TruTurn, gear and some other things and see where I can get it down to now.

Default dcronkhite - WOW!

Hi Doug and all,

First, I'm not picking on you Doug, you're a well know figure in the giant scale ranks so I know you know what you're doing...but...

Are you sure you didn't mean 5lbs 15 oz? Either that or there's a huge discrepency in the weight of the airframe as we're getting them. I figured the equipment differences out between yours and my plane and you have a minimum of 12 oz more equipment in your plane, but it only weighs 2 oz's more than mine. That's a huge difference in airframe weight.

I've noticed that a few other of the posts here are also way lighter than others. I wouldn't have thought there could have been so much difference in the weights when the bare airframe and wings only weigh 3.5 lbs. Can everyone please start saying how you weighed your plane. Digital scale, calibrated or not, fish scale, bathroom scale. I'm sure everyone is being straight here on what they think their weights are, but they're pretty meaningless if they don't correlate more closely. If you have a plane that seems way too heavy, or way too light, you might try and get ahold of another scale to double check.

BTW, I'm using a digital, .1 ounce accuracy, calibrated scale. There's no big trick to calibration. You just need to get some accurate weights (I borrowed a some calibration weights from my post office) and see if they match up to what your scale says.

Bill,

I do think there is a large swing in the weights from kit to kit. I checked mine on 2 different scales to be sure. My scale says 4lb 15oz, the other scale said 5lb 2oz.

Default Thanks Doug.

That is great then. I remember that there was a big difference in the airframes on the Dave Patrick Extras when they first came out. The same must be true here.

Realistically it doesn't take much to make a big swing in the weight of an airplane this size. Change the density in the plywood used to build the fuse and you add several ounces. Seems I just got lucky on mine.

I'd really love to take the autocad drawings used to manufacture this airplane and build my own. I'd bet I could do it under 4 pounds if I really tried.

I weighed mine on Sartorius Digital computer controlled scale used in our body shop that is zero'd every couple of months, its purpose is mixing automotive paint formulas and is accurate from 0 to 25 lbs and reads to the 1/10 of a gram and is accurate to +/- .05 grams, I just wish it were off by about 8oz!! LOL

Not holding my breath tho...

I don't think people realize how much all those "little" savings add up. When I build and ARF I have an accurate digital scale near by and weigh any suspect parts.

For example, on the Funtana the wheels, axles and nuts were HEAVY. I saved over an ounce by using lite wheels and 6/32 bolts instead.

I think the throttle pushrod was nearly 3/4oz from memory? Left that off too and used a micro servo mounted on the engine mount.

I did leave off the wheel pants and spinner to save about 3 oz.

I didn't make any structural mods.

All those small savings do add up.

Default weight

southern_touch9:

...and my T3D isn't a Funtana and it weighed 5.4 oz......SORRY southern_touch9, I couldn't resist.

geoharry:

I plan to switch out the axles for 6-32 or 8-32 hardware too when I get my CF gear.....and I wanted to find lighter wheels but didn't know which ones would be best. Which wheels are you using?
