Very nice...... looks like you have to be on your toes with all those trees around :-)

My flying spot is similar... but i think that makes it even more challenging.... adrenlin is my drug of choice and getting close to the trees gives me a good dose of it :-)

No doubt. lots of trees here, I try to stay above them and it makes it hard to try alot of stuff like inverted flight, I fly in a cow pasteur when I want, but its just easier sometimes to go in the front yard rather than packing things up. Man this is really getting my adrenaline going today. I'm pulling off some loops already. I tried holding it inverted and it came right at me, then I recovered. Man I'm shaking pretty bad. Havent done any rolls yet. I still need to work up the nerve. You know, I've found that one beer actually helps my flying alot. Slows the heart rate just enough :)
Sorry about the video quality I'm not sure how to make it great. It looked good on dvd, but then I had to convert it over to avi. I used avi.net to convert. I'm sure theres a better program out there for this.

I have been practicing loops and rolls on the simulator.... the G3 is very touchy.......in real life i find it easier to roll than loop and also to go inverted from a roll than a loop. I dont seem to jam the collective as much rolling which helps me hold steady altitude instead of shooting the bird straight up :mrgreen:

i still need to either get a tach or lose the stock woodies.... i am scared the blades are gonna come flying off everytime i switch into idle up :-)

scared is good ... no? LOL

Everything seems easy on g3. I use it all the time. I like an overpowered motor on the mx400. Seems like a good one to practice with. The real things always a bit different though.

My tail don't hold as good as the one on g3. It does fine until my headspeed drops coming out of the flip or whatever. I know for a fact I shouldn't try any tic tocs with the stock motor. I might get in, what? one or two before it hits the ground? It just needs a bit more power, I'm using stock all wood blades, without the holes. I noticed some are all wood and some have the holes all the way across (which tend to flex too much IMHO). My throttle curve is about normal in idle 1 but in idle 2 is almost flat (100 inh 95 inh 100). It handles a bit better with higher headspeeds. But still lacks alot of torque coming out of flips and stall turns.

I really put my packs through hell today, Flying 4 dnpower 2150's 3s (2) 15C (2) 20C. Good packs but the 15C's (actually learned on these 15C packs). I'm guessing 80 flights atleast of figure 8's, circuits, and stall turns. I can start seeing the power loss now. Especially after what I put them through today.) I got exactly 4 minutes on one of them today. The 20C packs are kind of new, so I'm still getting around 6 minutes on them. Leaving them at around 11.2 - 12.2 volts at the end of each flight, otherwise my heli gets to heavy to fly. DN power are actually ok packs. I think my efficiency will be better with the align 430L 3550kv - 11t pinion. ( Align cf 315 blades)

I am currently running the 430L w/12t pinion on the stock blades .... thats what scares me :shock:

plenty of power with the cheapo HK 1700mah 20c packs (all i currently have) after 5 minutes of hard flying the motor is barely warm :mrgreen:

i plan on getting some better batteries in the near future and hopefully extend my flying time.

yeah sounds like you have some insane headspeed, are you running 35amp esc? I was gona try with a 25amp, I'm hoping the parkbec will take enough load off it to work. I think I'd be afraid of other plastic parts flying other than just the main blades (which could be pretty damn bad). Plastic blade grips, and blades on the tail don't look that strong either. Its a constant upgrade. I'd sure like to have a 450 xs.. Guess thats what it will look like when I'm done:)

[racerman27410]

yes i am running the matching align 35amp ESC...... the headspeed is insane.... cant use full power since the tail blades start making a bad vibration/harmonic whenever its over 90%.... smooth as silk up to that point though.

i really need a tach.

Well, I've ordered a 430L 5330kv motor and 11, 12, 13t pinions.. I'll be using the 11t when I get it, I figure just hover low for a half pack or so, see how the esc holds up. I really need a 35amp but I'm flat broke as it is. First sign of throttle being cut and its out of there.

:dontknow My mx400 pro broke last night in the air when doing a pointed loop nere the top it bogged some . I just starting loops 2 weeks ago. Mostly damaged , just using a spare x400 and putting the pro parts on it with aluminum center hub. The mx400 seems to have a slow roll rate. I never tried one. I,d be up real high to try a roll . I was always worried about the ball links hitting the blade grips if trying to get to much pitch or roll. Know I'm going to be scarred to do tricks with it. Something broke in the head or mabe I had a blade strike or the stock blades broke. Iv'e been thinking about a trex head and blades, to get better roll and I'd feel more comfortable with an all metal head. Cool video.

Thanks.. I just started rolls a couple weeks ago, If you can loop it, you can roll it, Just start up high with some foward speed, slightly at a down angle, and down wind, then initiate the roll with confidence. Just keep the aileron to one side until it completes. You hardly even have to touch the throttle side. It rolls pretty good. I'm currently trying to overcome the fear of holding it inverted. I do it up high for a couple of seconds but its harder to gain bearings when its high. I think it will be easy down low to gain perspective. I just need to overcome the fear and commit to doing it. Best thing I done to the 400 head is add the trex grips. Gives it better tracking and allows for the align blades to easiely be bolted on. Other than that I'm pleased with it, a bit on the heavy side when comparing to the trex ccpm but hey.. Its a good flying machine when its tuned properly. Just go over the head really good, check every nut, bolt, screw, belt, mesh, and links. I like to use a flashlight to inspect closely, maybe even a few warmup flights, slow and low working it faster and higher. First sign of trouble bring it back down and figure out. After that just have confidence in your machine. You will overcome. Also it seems easier to fly with a higher headspeed. You might try running it at a flat 90% or so. But do so at ur own risk:)
