Status: offline 		Randy, your correct with the pinion choice. However with my set up a 13 tooth pinion will give me around 3000 rpm headspeed, too much for me right now. With the 11 on she is a real nice flier. Just need bigger lipos. Going to have to jump on the Kong powers I have at the store, cause my poor 1800 15C's just can't handle the power draw and I don't want to cook them.

Mark, yes I have had an addition, and it's more than I dreamed it would be. I finally understand why the Trex guys rave about these machines. They are just pure joy to fly. I couldn't be happier with Big Blue!

Now I'm up at the inlaws on an acreage and have been flying battery after battery after battery. I will say this, orientation is a real pain! I lost my #4 in a tree and took out a main gear trying to get her out. I really have to spend some quality time working on slow figure 8's and nose in hovering. Man nothing worse than having a heli nose in orientation coming at you at full speed and having a brain fart. Good thing the #4 is a tough little bird, she can handle pilot stupidity well. Guess I'm off to practice practice practice. With two nice CP machines begging for some loops and rolls I had better improve and quick!

Status: offline 		Stump you IDIOT! It is never pilot error, out in the country the UFO signals mess up the tx, duh! AND that is why you crashed Glad to hear you are having some fun. Too windy this weekend. I flew the CX some in the garage. I am trying to get my neighbor into it also. I let him borrow my Havoc Heli for a few days and then he flew 2 packs on the CX. My CX is hard to learn on since I tweaked it up. Might put more fly bar weights and move the servo horns back.

I understand you are having a good time with your helis but I'm not hearing much about the other guys. How's everyone doing? We are still sitting on significant (not unlimited, but significant) funds in the Iraq Soldier Flight Fund - so if you guys need stuff, give me a holler. And that would include your experimental lunacy. This fund is all about helping you guys enjoy your free time. And I certainly congratulate you on your willingness to look out for the other guy's need first.

Mark,
For an update on our flyers:
Belt CP - One of the Belt CP flyers gave up on it and gave his heli to Curtis. So, now Curtis have extra parts for his Belt CP. He's been flying pretty much everyday. That's the Belt CP I flew into. I think another one just emerged out of hiding and is currently awaiting parts to get his flyable.
Blade 400 - Two new guys got B400s here. Keith is flying his as much as he can from last I talked to him and the other one just got back from R&R and hopefully started flying his B400. My Mentor, Justin is up again after a freak crash from aerobatics and is flying his B400 without a canopy (awaiting one from what he told me this morning). And you know my story of course - mine's broke again
T-Rex - Haven't heard from them in a while
Dragoness - He's been flying here and there. I actually caught him flying one day.
CX2 - The guy who bought CX2s ended up not flying them at all. He said that he is going to give them to his kiddos. Mine is still kickin'!
GAUI 200 - Bruce has this 200 that he's going to make into an out of this world heli - awaiting crazy parts.
Falcon 40 - That heli is just a tough little cookie. Same owner as the B400 guy who just got back from R&R
#4 - My project/problem child at the moment. For some reason the 3-in-1 was burnt when I plugged in an 11.1v 20C 1350 MaH battery. I thought that the EFLH 1031 could handle an 11.1V battery? I finally got the last Y harness, but since the 3-in-1 was broken , the tail did not have enough authority to keep up with the main. So there goes the #4 - still down . She did lift off the ground and was out of control. I just need to acquire a 3-in-1 to get her up and hopefully this one won’t burn out like the last 3-in-1. I'm actually just going to put her back to normal configuration and just use the 7.4 LIPO, that I know works.

So, there's an update on how things are going here. Our schedules have changed and we try to fly whenever we get a chance. I try to talk to others if I catch them and ask about their flying. As far as parts are concerned, I guess people can always use commonly breakable parts. I guess we can always support Curtis (Belt CP), since he's the youngest and he can use the most help. B400 commonly broken parts would always be wonderful, since there are 4 flying here.

Kenn

Status: offline 		Morning all! Hope everyone had a great weekend.

Mark - Good to hear from you. It seems like it's been a while. Love the report on the belt. I've been considering some more heli purchases and was wondering about the stock Tx on that baby. Have been going back and forth between buying a belt or picking up a DX6i first and the cp at a later date. With that report I may have to reconsider going the other way around. I'm still in super training mode with the falcon right now but I can now see the light at the end of the tunnel. Sometime this summer I'm sure I will bel ready to move up.

Ken - Love the 4! Looks like a monster. The 400 canopy is just great. Can't wait to hear about how she flies once you get her back up.

Max - HaHa! UFO's! I tangled with their signal interference this weekend as well! Had the chance to get the falcon outside last night at just before dusk as the wind finally gave me a break. I was having a blast in my back yard. Flew 1 pack almost all the way through doing nose down passes real fast with stall turns and plenty of piros, until the alien signal sent the falcon at top speed, nose-in, directly at my head. I think the aliens were trying to take me out. At any rate as it was coming in I probably could have gotten it back if my piloting skills were better as it was pretty far out when it began it's kamakazie run. I instead paniced and dumped the throttle because not only was it heading at me but I was standing with my back to the house so even if it missed me the wall is a much bigger target. The Falcon skidded to a stop literally 6" in front of my feet. I've crashed it way worse than this before with no damage however no such luck this time. There was no damage to the head, blades, tail, or canopy still I managed to break the frame in half right at the weak point under the aler. servo. It was the only damage. This ended my outdoor flight while there was still plenty of light for another pack. Was a bummer considering I've been waiting all week for the wind to cooperate. Oddly enough I've noticed a trend to my bad crashes. Every time I have done something like this including the day that my uncle hit the brick wall it's always with this one particular battery pack. I run 3 identical packs so I number them and this is pack 3. This is the 4th serious crash that this pack has been involved in. I've actually not had a really bad one on any other pack. I think pack 3 may have to be retired from outdoor flight and reserved for hover training. It was funny, I thought about that very thing as I was plugging it up for the flight Soulda gone with my feeling and put another one in.

Wanted to talk a little about the newest mod to the falcon. I received a new motor from a friend last week. It's the stock motor from the HBK2. I have to say wow! This thing is a torque monster compared to either of the other motors I have tried(stock, CPP 11t) I did replace the 9t pinion that came on it with a 10t. Broke it in and have been running it since Thursday. I'm getting slightly less run time but only about 30 seconds. Looking at about 9:30 right now with 900mah packs. The magnets are very strong in this motor. When spun by hand the pinion puts up very noticable resistance were you can hardly feel the magnets in the other 2 I mentioned. It's noticably heavier also. I don't have a gram scale so I can't say exactly how much but quite a bit. As a result the headspeed is higher at hover but the motor is powerful enough that I am lifting off at 50% stick with that higher headspeed. I did have to make quite an adjustment to the tail to get it in line but now that it is I'm loving it. It climbs very fast when throttle is applied but I do now have to make a rudder correction when I punch it. This is normal as far as I'm concerned. I've not had to do it before because I've not had a high torque motor before. The jury is still out however. These motors are known to run hot and give up early in the kings at least. I do notice that it does run much warmer than my other motors but I can still touch it with no problem after a full pack. I've now logged 16 flights with it and it seems to be going strong. My preliminary findings are, although extreamly underpowered for the king I think it may be the perfect brushed motor for a 300 class FP heli so long as it dosen't crap out on me too soon. Time will tell. Right now though I am enjoying all the power and having a blast.

Have a great day all!

Status: online 		Kenn, more great photos ! Don't take this wrong, but it's not the helis in your photos that stir me. For me, seeing those photos of where you are, what you are doing, and how you cope with it stirs emotion.

Do you guys have any problem with the fine dirt/sand getting into your hels?

After being in contact with Mark the last couple days I'm guessing he has plans to get you guys some more parts, etc.



UTM, reading all your reports are like stepping back in time 1-month for me I crashed into my house three different times It's amazing how much we learn, and improve weekly

Keep us informed about that motor. I know Shane (Stump) has tried that motor in his #4 as well and has reported similar results to yours! If you went to a 11.1V 3S pack you would have MONSTER power, but probably real trouble with the tail keeping-up. If ya do try a 3S battery you will have to drop back to probably an 8T pinion. You think it has torque with a 10T..., an 8T on 3S would probably tear itself out of the frame!

I do really like the Slo-Max motor with a 9T (300gram AUW). I feel like it is a very good compromise of torque and run time for this size and style heli. I get 14+ minutes on my 7.4V 2S 1300MAH batts. and could get more if I wanterd to push the discharge a little more. My batts. go back on the charger at 3.6 to 3.7V per cell after 14-mins.

Status: offline 		RMG - Glad I can take you for a walk down memory lane I've been working really hard to improve my flying, but taking a hit like that just knocks me down a peg or two. I still can't believe I broke the frame in that crash. It didn't seem too bad until I picked it up and the tail was hanging 10 degrees to the left. I crashed it a couple weeks ago outside and trashed it but still no broken frame. Funny how that works. Luckily I had a spare in the parts box and got it switched over last night. Ran 2 more packs through in the garage and everything is satisfactory. It was my last one though so I'll probably order a couple as a preemptory strike against my next breakage. I should have some new head parts in my mailbox when I get home. Can't wait to get that old worn out core outta there and tighten up the head again(mine is real sloppy). I get a little tired of chasing it all over the place. I'm exaggerating it is pretty stable still just a little sloppy in cyclic control and I have to make more than 1 correction to get it stable again after drifts. I like being able to make my inital correction and be done with it.

Happy hovering all! Have a great evening.

Status: offline 		Kenn,
A couple of posts ago you mentioned a Fiber blade that you said was excellent. We sent a couple of sets of B400 replacement blades that appear to be plastic, but the description is a fiber reinforced plastic. I seem to recall that it's actually an Align blade for a Trex, but with shim washers they are supposed to work well in the B400. Is that the blade you are talking about? I'm looking for something more durable than woodies but not as ornery as carbon fiber. I want them on my Belt CP.

Talk to me Kenn.
Mark

Status: offline 		A holiday Monday I'm soon not to forget. So I'm pushing my self more and more into fast forward flight and really really want to get stall turns and basic circuits down. Beautiful day for flying warm, almost zero wind, excellent day. First up the good old number #4. Well managed a couple of ugly stall turns and was half way through a stunning bank turn, come through the turn and totally lost orientation.....down, blew the head clear off, toasted two bearings, and busted up my last guiding ring.....crap grounded!
So out comes the King, worked on side in's having fun doing a tail in box circuit with her then spun over to right side in orientation. Started a nice ff run pulled back on the elevator and got her nose way up ready to do a nice stall turn, spun the tail and those damn UFO's appear out of nowhere over rotate the heli and all of a sudden I'm in an orientation I have no idea how to recover from. Not being a stranger to this, I remain cool and think to myself I can recover this......well one tail boom brace, feathering shaft and an HS55 later I will try again! Being as I'm 3 hours away from parts, it's gonna be a couple days before I'm airborne. Good thing I have no batteries that can fly the CX450 or she would be sitting in pieces too!
Orientation.....what a nasty nasty critter!

I find when I do stall turns and loose my orientation that I just give it more throttle as I spin the heli around one more time. This only works of course if you are over 30 feet up. I always fly above 50 feet. I loose my orientation just on the tiny size sometimes!

I feel for ya friend! The positive to take from your experience it that you know you will never get better if you don't get out and try! When I crashed the FP last week I just told myself, "it's the price of learning this hobby".

Better days ahead Shane, don't let these crashes set ya back bud'!
