Your Falcon needs a lower CG before you see a drastic change in stability. Basically, a Falcon 40 should be almost as stable as a Trex450 without wind, if it properly setup. Try to lower the battery much more, closer to the landing skids. For safety, I still wouldn't fly a Falcon indoor no matter how well it's setup. My 2 cents.

Aw Life it's good to be on the safe side but I see no real problem with flying the falcon inside. I have hit almost every piece of furniture in my living room with it and the only damage is a couple of scrapes on my coffee table leg from when I set it down hard and the blades were barely knicking the leg. With stock or even upgraded brushed motors the headspeed is just not high enough to do any real damage. That said if you hit the drywall you will put nicks in it. Trust me I've even hit myself with it 2 times and it did put a very small scrape on my hand but all in all not a dangerous bird in stock form.

Note - Great life does run brushless so his headspeed will be higher than a stock bird. If I was running BL with woodies I wouldn't fly it in the livingroom either. Brushed motors and plastic blades = a ton of living room run

And that's my 2 cents...

Status: offline 		I run brushless with woody blades and I still fly inside. It's much more fun now for me to fly outside, but inside flight can still be had. Of course, I don't crash as much as I used to. I also should be getting a parts order today, ordered an 11T pinion from USHobbySupply - maybe that'll bring up head speed so I don't need quite so much throttle.

Michael - I see ya lurking! Long time no see

Status: offline 		Broggyr - Oh it can be done I'm sure. I also am feeling confident enough with my hover abilities to do it and not worry about crashing. I suppose I was just saying that with a setup like that damage to surroundings is much more likely in the event of a disaster. Would most likely nick up the furniture pretty bad if it did jump out at'cha

Status: offline 		Ya when I nicked the coffe table I quickly powered down the heli and made a dash for my stain sticks. Good as new before she even knew it was damaged. Don't know why I cared so much anyway seeing as I made that table but you know, better safe than sorry

When I first started flying in the house I would get a nice stable steady hover going and all of a sudden the heli would dart to one side and I would have a hell of a time getting it back to the center of the room. It took me about a week to figure out that everytime the AC kicked on the vent was blowing directly at the heli and kicking it to the side. Man did I feel stupid after spending a week adjusting on the heli and trying to figure out what was causing it.

Status: offline 		There's no way I could see flying in my living room. There is much to much stuff to hit piano, coffee table. glass bookcase doors, family photos -. Nope! Mine's not nearly 17'x17' either. I could go back to the garage, but I never was able to get a hover until I got it outdoors. Too afraid of hitting those hard walls. Even outside in still air, my Falcon seems to have a mind of its' own sometimes. I can have a very still hover for a bit and then it decides to move all over the yard. I can get it back under control, but it takes alot more space that I have in a garage. Sometimes I think a light puff of wind is to blame, but I can't be sure. It's just like a marble on glass. When it starts moving, it takes a bit to get it stopped. I think the FP plays into it some too because I have to work the throttle all of the time and when throttle changes, that makes the chopper want to move.

I broke my 4th center core last night. This time, it snapped off completely right at the top of the steel main shaft. Yep! It hit hard. It may have also made contact with the edge of my patio slab, but I don't know. I lost lateral control completely. Well, I've been flying with a partially stripped roll servo , so no surprise. It was mostly working OK as long as I stayed away from maximum roll stick, but evidently, either I got out of that zone or something else went wrong. I was pretty lucky. Didn't break anything else that I can tell, but did lose one head bearing someplace in the grass.

Oh, well. I'm expecting a shipment today with a replacement servo and 4 center cores. I think I'm going to put a steel shaft thru the center of the two top forks which are already drilled thru and then fill the gap with epoxy as some others are doing. I'm thinking this should make it much stronger where it usually breaks.

I counted up all the bucks I've put into my Falcon since I bought it 5 weeks ago. Yikes!!! $290!! Of course, I bought 1 1/2 Falcons to start and I I still have a bunch of spare parts. I'm on my last tail motor though, so I gotta do something about that. Also, $70 of that went toward batteries and LIPO charger. $20 of that $70 was for 2 spare NiMH packs that won't lift me off the ground anymore. Motor is too worn I guess. Should have gone to LIPO right off the bat. There has to be some major difference between my setup because I need 11.1 v to fly and others are doing fine on 7.4 to 8.4 v. And I'm not in Ablq like Dave. I'm wondering if my gear mesh is too tight, but I don't think I can make it any looser and still fly. My tail rotor turns really hard by hand, but that all seem to be due to the cogging resistance of back driving the motor. The tail motor gets pretty hot, so I'm going to add a 2nd heat sink.

Later,
Jerry

My tail motor dosen't run rough when spun by hand. I have had my share of tail issues and I have found that if I allow a little slop in my tail it runs much smoother and not as hot. I push the tail rotor all the way on tight and then grab the gear and pull out until the gear sits just at the edge of the pinion. It will stay on when RPMs are down but when they are up the rotor pushes against the tail box so the gear gets fine contact with the pinion. If I push my rotor all the way tight I end up running real hot and the tail won't hold as well. My guess is that the gear is not a precision engeneered piece and may not be completly straight or round even though you can't see it. The little slop allows it to move where it needs too on the pinion without binding wheras if you press it on tight the movment is restricted and binding can occur.

On the motor what pinion are you using? 10t(stock) or smaller/bigger. I run 11t pinion on a 370 and my 7.4v lipos are plenty. You may try going to an 11t pinion if you can't get enough lift. This will increase headspeed for you. If you're already on 11t or higher than maybe it is time to change the motor out. I am going to a bigger battery though. Not because I can't fly with mine but because I need a little more weight for COG purposes. I have a LoongMax 2s 1200mah 20C on backorder. Weighs about 89g where my 900mah weighs 49g.

Sorry to hear about your crash. Thats a bummer Hope you get it back running real soon.

HeHe! I did the same thing when I first started flying mine. Couldn't for the life of me figure out why all of a sudden I wouldn't be able to keep it still. Stupid modern conviences

Status: offline 		I set my pinion mesh on both main and tail motors by loosening the motors and sliding them back from the gear, then putting a peice of notebook paper between the pionion and gear then sliding the motor up tight and tighting the mount screws. Then I turn the gear by hand until the paper is ejected. This gives me a good backlash setting between the pionion and gear. It also allows me to repeat the same setting each time so that aspect of the flight is always the same and I don't have to learn a different feel evertime I change a motor.
