sorry i dont even have a heli here but wondered why there isn't more talk of lightening frames since the biggest complaint is flight time. i see there is plenty of stuff plucked from the rear of the heli to increase speed, but no one seems to have taken a dremel and cut out some of the dead weight aluminum? chopped leds out?
are the frames fragile? from pics they seem over built and a candidate for weight loss.
6025-1 should be here in a week...looks like fun!

I actually don't have an issue with the flight times.
An average flight for me lasts less than 2 minutes, give both the heli and pilot a little rest, then maybe another 2 minutes. At this point I'll let the heli cool and fly another one. Honestly, I don't think I'd even want to fly one of these little guys more than 5 minutes on the trot.
Anyway, there are quite a few people putting their choppers on diets through various means, some of which you mention. Of course once you start monkeying around with the structure a number of things will change, not all for the better: a properly located CG, good structural rigidity and durability are more important to me than a few more minutes of flight time and higher speed.
That being said, I did modify an S107 with a bigger tail motor, replacing the stock fuselage with a light weight one to end up about where a stock S107 is in weight. It's a blast to swoop around my LR:

Of course once you start monkeying around with the structure a number of things will change, not all for the better... One thing I find that if I fly a helicopter with the canopy and other things taken off (so that it is very light) is that it gets more buffeted around by rotor wash coming off furniture, walls, the floor (with annoying ground effect) etc... The standard weight of the 6010 is better for that, and the slightly heavier S107 is even more stable yet again. I'd like a heavier helicopter, not lighter. I'd also like onboard sound effects to make it sound like a real helicopter instead of whirrrrrrrrrr, but thats not really relevant here. |

Well, based on some ideas I've stolen from "the other forum" I'm working on one S107 to a super modified speed racer:
Frame plates replaced with Lexan.
All tail deco's removed.
Excess plastic removed from skid mounts and bottom tray.
Canopy trimming/possible recreate from light materials.
Picooz.AirHogs tail rotor with boom flip.
The heli I'm executing this on is out of commission right now and I'm waiting for my scale to arrive so I can track/log these changes. I've started to fab the new lower frame plates but that's as far as this has gone so far. I'll post back as things go...

very interesting that the weight reductions can drastically take away stability. my only experience was the fun little picoz and that one did pretty well after weight was taken off. it too got a little squirmy but overall the trade off was good.
i watched one video that showed the tidy bowl effect ive read about. thats a pretty big change in behavior. its kinda disappointing from a tinkerers perspective that they just fly well out of the box haha. i will try some reductions anyways...its no fun leaving well enough alone

 How's this for weight reduction?  The skull and wings are made of Crayola's super-lightweight foam "clay" -stuff, and painted silver.  You could use this to make a small canopy with, too... This is made from an 8818 copter.  I added a San Huan 6020-1 GYRO-eq'd PCB to it. More: www.air-sharp.com/helisangelcopter2.htm |

ah i see what you guys are saying about making them too light now. the 6025-1 came in and as i learned and you all already knew, it flys perfect in stock form.
all ive done is cut the plastic between the landing gear out (the main spur gear protector) and taken the tail struts off. i also cut the canopy back so the front motor can receive some cooling. i may try to cut the frame up a bit but flight times are already plenty of fun.
neutral flight is almost as fast as stock forward. reverse now puts on some good brakes and can slowly fly in reverse. forward flight of course has gotten alot sportier and i can even get some blade strike if i really work it hard.
ive parked my blade mcx for the time being since the 6025-1 is so much fun! tuff little bugger too!

That last line should be quoted somewhere...it would get ME a ding over at...I forget where...

taking the inner al. chassis plates off the S107 saves about 2.5g and doesn't seem to affect the structural rigidity much if at all. Definitely quieter with much improved throttle response! www.youtube.com/watch?v=Fm8f9TR4NkMAttachments:

I have seen many, many and I mean many custom modeller's do creative things...this takes the cake! Brilliant work - my hat is off. D. |

Edit: would you be willing to try your creative hand with a Litehawk? Plz pm me here (or via our forum)...pretty sure I could arrange a "sample" for you.
David.
