Averaging the two weights I got with mine, 10lb 11oz on a postal type scale and 10lb 6oz on a bathroom scale, mine is around 10lb 7oz. That is with a full tank of fuel as well. With the changes I have planned on mine, I will be right around 10lbs fueled. With the removal of the flybar when I switch to flybarless, I am sure I will be under 10lbs fueled and ready to fly. So I do not see his weights as being incorrect at all.

You'd be surprised how much the Flybar and it's mechanics actually weigh. The Stock Flybar paddles are what 30grams (1 oz) each. So that is 2oz right there. I be the flybar is over an ounce as well. I can see it would be very easy to take 4-5 oz out of the heli by simply removing the Flybar and its mechanics.

The above weights that I talked about are with 2 x 6 oz batteries as well.

I think you have to go with the postal scale

The bathroom scale is not accurate in my opinion. The postal scale is dead on I know because when I ship packages out to people all the time I measure them at home and when I go to the post office its exactly the same as to what they measure there on their scales.

I tried measuring stuff with my bathroom scale in the past and #1 its not significant enough (not down to the oz.oz) and #2 it doesn't always give the same reading.

I believe you're at 10 lbs 11oz as your postal scale says. Mine was 10lbs 5.2oz with no fuel no generator and 640 mains (you probably have 620's) and 3oz less for muffler differences so with a full tank and smaller mains the 10lbs 11oz make sense to me.

Its snowing today and I could go fill the tank and tell you how much the fuel adds to the heli if you want.

First off, my postal scale is a cheapie. Its max weight is 11 lbs. The Radikal is on the extreme end of its "range". When it comes to things like this, the further you are on the extremes of the range of a device, the less accurate it is.

Just weighing the Radikal on my bathroom scale it is also on the extreme of it's range. So to compensate for that, I put a 50lb weight on with the Radikal. This is a digital scale and weighs in at 10ths of a LB. IE: 60.4lbs = 60lbs 4oz.

I have weighed my Radikal on more than one day and numerous times over those days and the weights are damn near always the same.

Since neither of these scales is "calibrated" or "certified", taking the average of the two scales is logical. So I will stay with my 10lb 7oz weight

Scales

Yeah my postal scale is a very high quality accurate scale, so I trust it 100% and it also matches their scales in the post office down to the same decimal point as printed on my receipts. Some people also go to the post office to weigh their helicopters, say you want to mail it and stick it on their scale....so that's an option if you want another opinion.

OK on yours, 10 lbs 7oz it is. Do you know how much the gas weights? I never weigh mine with gas, always dry.

What's the whole tank worth?

I'm not even sure how big it is.

Can you weight it empty too so we know the difference?

Flight Time: More than 30 Minutes with consumption of 300ml
300ml = 10.14 fl oz

so you are looking at around 8oz of fuel. Figuring that oil is a little heavier per volume than gasoline.

CnB

You're right in the same weight range I am. Here is the weight of the stock canopy (no decals) as I wrote it down when I weighted the individual parts:

Don't have a trex canopy handy, but I expect that its lighter though can't be more than 2oz max lighter I'm guessing.

I guess I am not as shocked as everyone else. When I install these new batteries I got yesterday and swap out my throttle servo, I am going the shave close to 7 oz off mine. That will put me right at 10lbs. That is fueled and RTF

I don't know sparx

The kit comes out of the box the way it comes out of the box. The only differences are the electronics you put into it - whether your gyro is 2 piece (611 for example) or 1 piece like a Spartan, if you add a governor or not, whether you use battery monitors or not, and the size of your batteries. Besides that there isn't alot to wiggle with if everyone is using the same canopy, muffler and aircleaner unless you swiss cheese the motor like Rodney did to save more weight there.

If I go with what I have, its 11 lbs fueled with no Jewel generator based on your saying the fuel is about 8oz. So I can lose 3oz for the muffler going to the Century. Maybe 2 more oz's going to 620 blades instead of 640's. And make it flybarless and then its another 5oz you say, and that includes adding the flybar electronics? If so then it would be sitting at 10lbs 6oz. Lose the gv-1 and its down to 10lbs 3oz I guess (haven't weighted the gv-1), what else? Not much, batteries are already pretty light, at 7.5oz for both. maybe another oz there going to lipos, so down to 10lbs 2oz. Oh yeah I remembered I have landing gear spacers, so they probably add another oz. Yeah, trade the 611 for a Spartan and you could make it pretty close to 10lbs, its not impossible that's for sure but now its also flybarless to ge there.

By the way

If you guys want to save more weight, you can get a Hanson ignition for it -- that's what I'm using. Its lighter than the stock system from Zenoah and also uses less battery power if that makes any difference.

So are you insinuating that we are not being truthful with our reporting of weights? Because I am sure getting that impression.

Some people are just more weight cautious when building than others Raja. I am one of those. It is not hard to rack up .5 - .75 pounds of extra weight if you are not careful.

If you use a lot of zip ties, that will add up. All that plastic spiral wrap everyone loves to adorn their helis with will rack up an oz before you know it.

Those GV-1s and GY 601/11 have those heavy ass controllers. I bet right there you are around 2 oz more on just those two items.

I do not run an air cleaner either. That is a matter of choice. But it is my opinion that a gas engine is of no more danger than a nitro when it comes to this.

Yes adding all those "gizmos" will make it more convenient to fly your heli, but you have to pay for that convenience with weight. I am just not willing to pay that price.

Servos can make a huge difference as well. Take the 8717s. Those things are just over 2oz. The servos I run are just over 1. Well, there is 3 oz right there.

How about the RX? You could easily see .5 - .75 oz difference in those as well. Chuck in a few zip ties with it and it could be more.

Now look at all these other little "gizmos" people put on their helis. Voltage watchers, Temp sensors and the like. Again, all that does is add weight.

When I build a heli, if it does not contribute to making the heli fly, I do not put it on there. I do not mind having to carry a DMM to check my batteries. All this stuff does nothing to enhance the flight performance and only contributes to taking away from it.

This is a "nickel and dime" game. This is the same thing that I have to explain to my wife all the time. If you go to one store and spend $100 you spent the same amount of money if you went to 10 stores and spent $10. For some reason she has a hard time grasping that concept.

No that's not what I said

So are you insinuating that we are not being truthful with our reporting of weights? Because I am sure getting that impression.
Reread my post, I went though it step by step and came to the fact that I can get it down to 10lbs if I do all the things I listed, so its quite possible to be there. But that's all equipment that I had on the shelf, and I want to have all the other electronics that I put in mine.

You're also right, some people build heavier than others with wire dressing, tie wraps or whatnot. Your weight savings methods I'm sure are alot better than mine, as I'm already heavier than yours even if I do all those things to lighten up.

The truth of the matter is the heli flies very well at 11 lbs, no worse than the Spectra or 1005. The only downfall I see is the autorotation hang times which are slim. I'm sure it can benefit more by losing a pound for that.

Ok I put mine on the scale and it weighed in at 11lbs 2oz, no fuel with 620's keep in mind my pull start is permanent and added aprox 4 oz. even if I took all my batteries and gv1 off I would still be over 10 lbs remove the gyro too and I would be just shy of 10 lbs. I must be a heavy builder.

The only way Im getting mine in the low 9lbs is to remove the engin! But that may impact climbout!!!!!!!!!!!!!

I have the alu Head, that may add some weight also.

Not mine, but I know whose it is.

Now we cannot see if the blades are on it. Definitely does not have a Canopy. So add those in and you are still under 10lbs. I am not 100% sure, but I think he has the blades on it. Shadow seems to look that way as well.

There is something more to your guys weight than you are thinking. Because getting this thing under 10lbs fueled and RTF is not impossible or all that hard to do.

it flys very nice at 11 lbs, I find it to be a relaxed flyer, I am very comfortable flying this thing around, compared to my vibe which weighs about 8 lbs. Even in confined spaces, in my back yard, its a pleasure to fly, Less of a chore than a 3d machine. It still loops and rolls great, but the way mine is set up its more of a sport flyer than a 3d monster, its a nice change from the vibe 50 and 90. It seems to be getting more stick time, I feel like i could sit down on my couch with a beer and a smoke and fly this thing all day. Only problem, its a b%tch getting a couch to the flying field, and the other members think its a little strange.

LOL!!!!!!!!!!

Funny!

Hey CnB...you need to take your truck to the field and you'll get your "sofa". Mine has a bedrug in it, its like sitting on the floor at home . I've taken it to drive-in movies in the summer, throw a couple of comforters in there and you got something soft and a cover to sit on, its like watching movies in bed, except its in the truck bed, on a bed rug!

Here is a link of me sitting in the truck bed while I fly at my field:

http://www.youtube.com/watch?v=vM6a...feature=related

I do alot of flying and the truck sure comes in handy while working on my maneuvers . As you know those things fly for a long time and while you can stand all day long its just a little more comfortable to sit - in fact, I almost think I fly better on my "sofa" than standing up sometimes. I just more relaxed

Incidentally, for what its worth, my canopy and blades add up to 1 lb 1.1oz with no decorative stickers on it. Not really sure what this guy's scale reads, looks like 9 pounds something, is that 1oz? Is it complete ready to fly with all the electronics? Not obvious from the photo.
