Awesome! I am close with mine, but just fighting the cg with 5000 packs.

How far off is the CG? Holding by the flybar, what is the difference in height from the front of the skids to the rear of the skids?

I have the flybarless version. Grabbing onto the mainshaft and holding it horizontally, I have to throw about a 203 gram weight on the back to get it to cg out right. I am gonna go with a little more weight because I have the 5000's as far inward (seriously) as I can go, so I want a little more room to work with.
Sorry for the Jacking cd5, glad to hear your maiden went well and hope it continues to work well.

I had the same issue with CG & ended up having to scrap my 5000 packs & go with 4200 packs which balance perfectly.

I am still confused how others are using 5000 packs. I have tried Hyperion & TP.

Most probably aren't worrying about the balance issue and just flying the model.

True with a good pilot you can still get around it, but why? That may be great for all around sport flying, but a better balanced heli will fly better for 3d. With a flybarless your system doesn't have to work as hard trying to keep it level in piros and in flight patterns.

I am using some 4500 volt packs and it balances perfect. I can see where 5000's would make it a little nose heavy.

Volt 5s 4500 35c are 630g each = 1260

TP 5s 5000 45c are 675 each = 1350

I am running the Hyperion 5S 5000 packs in my Logo.
Specs say 621 grams per - but I haven't actually weighed them.

That's kind of what I mean, I would rather fly a slightly nose heavy model than put close to 1/2 lb (200 grams) on the tail of a model. That's why I put up for Kyle and Bobby (and now more are chiming in) what packs they are running and how the model balances. With the new and ever changing lipo technology, 5000mah packs today weigh the same as 3800 mah packs of 2 years ago. And pack more punch.

I would rather run the 5000 packs & yes having a slightly nose heavy model isnt generally a problem (it still flies) but with FBL it tends to want to dip the nose in strange ways.

Its not comfortable at all.

If I add 35grams of weight to the vertical tail fin, then it will balance out.

MA to machine steel trans. clamp?

Can Brian from Miniature Aircraft have a 128-155 transmisson clamp made out of steel. I'm not sure how much weight this would add, but most will only need 25 to 35 grams as it sounds. This would be an easy way to add some weight for balance for those of us using larger packs. Or some steel weights machined that could attach the transmission clamp, to be secure. Would be a nice option that MA could make happen

It sounds to me that the batt. size range for the Furion (4000 to 5000)was introduced for the flybar model, then when the FBL head was made, and that kit produced, those 4000 to 5000 pack sizes remained without thinking about the CG and how it affects FBL flight using the 5000 packs.

Kyle Stacy is flying the 6 flybarless with 5000 packs and says he doesn't worry about balance, just flys.

If only we could all fly like Kyle, we wouldn't need to worry about balance either!!

To tell the truth I've never worried about CoG on the Furion 450, just correct on the sticks in flight, that way I could swap pack sizes no problem. Not sure how much of a difference this makes on FBL though, I'll find out soon enough!

kcordell, if you do not set a helicopter up to be at its best/best for you, how do you know this is the best helicopter for you? Why because it sucks the least? Basically the number one thing to have is a pilot that can fly and a heli that is properly setup. This has been stressed as long as I can remember when I started flying, along with practice, practice and practice. When you are starting to learn inverted flying it is easier to progress with a heli that works with you, not against you. I like to set my helicopters up to be at their best so I do not have to troubleshoot or fight the heli.

All is cool!! im using 4000mah 5s in my set up. i not worried about the lower capacity and it ability to deliver current. The heli balances and flies nicely but id does have a flybar so balance is not as crucial either. (even though i have good balance). Bigger packs will deliver more "c"s but i dont know if im going to have a big amp draw that will require monster packs.. im running 10 degrees of pitch and a 12 tooth pinion and radix standard 600mm mains and it suits my style of 3d. (i try and fly more like Colin Bell rather than Tareq.).If i went to a bigger pack, id be adding weight and still not calling on the amps that a bigger pack will deliver. So for me a big capacity pack will tend to evoke the Law of Diminishing returns (and diminishing bank account).The set up wont bre foreveryone but im happy with it.

Good to hear, I was up last night doing all of my soldering so now it is time to start setting up and get ready for a maiden. I went for with the 5000's for pure flight time and 620 blades for stability. I am just starting to do more 3d (piro manuevers). To be honest the 5000 30c packs were just about $20 more than the 4000 40c packs I was going to use. It seems if you use a pack that has a constant output that matches or exceeds the maximum motor amp draw, then the batteries do not puff as fast and are ready for recharging faster as well. Just my take.

raptorwoody:
Yes, balance can be a key issue in how well a model flys. Back in the olden days, we had fuel tanks up front and the CG dramatically changed during flight. Made keeping the model trimmed very difficult during fuel burnoff while doing a contest schedule of maneauvers. Then as designs progressed fuel tanks were located more towards the main shaft reducing this issue. Now we have electric and this issue is gone altoghether (how much do mah's weigh, anyway?). If you are going to fly nothing buy 5000's, have the model set up best you can, you will adapt and still get the best out of the model. Although many don't believe it (I will send Castle log data to anyone who wants to see), I am running FlightPower 3800's, perfect balance, and I get 5 minutes of flight time with mild 3D flying. When recharging, I am only putting back in about 2500mah's so I am well under the 80% rule and probably could get another 30-45 seconds flight time if I wanted. My view, I don't want to push it, I like my batteries and I am kind to them (I never charge over 1C either).
