Status: offline 		Well now i know. The swash plate is inverted. In idle up, i have full -10 when the stick is totelly up. a +10 when the stick is full down. How can i change that ?

Status: offline 		it would, perhaps, but did you set the radio to the right heli and swash type as above? Please verify that the left and right (front) servos are plugged into channels 1 and 6, and the center (rear) servo is in channel 2. That done, then you are halfway there.

Move the right stick (assuming mode 2, North America) to the left and right- if the servos move in opposite directions, you're golden; if not reverse either channel 1 or 6. Then move the right stick fore and aft- if the swash tilts, then you're good; if it goes up and down, then reverse channel 2.

Lastly, push the right stick forward and verify the swash tilts forward. If not change the sign of the ELE AFR- i.e., if it is -60 change it to +60, if it's -50 change it to +50, and so on. Then move the stick left and right; with the stick left, the swash should tilt left, and the stick right, then the swash right. If not, change the sign of the AIL AFR. Finally, DISCONNECT the motor from the ESC, and move the left stick up and down; moving the stick up should increase pitch (all servos move down) and down should decrease pitch (all servos move up). If not, then change the sign of the PIT AFR.

With the above done the radio is programmed. Motor still disconnected, move the left stick to the middle position and adjust the servo to swash links so the blade pitch is zero and the swash is level. You can then proceed to set the AFRs to the range of motion you want.

Status: offline 		Thanks Oster.

I've heard a lot about the Kasama head. The thing is, it supposedly wont work with the stock TT woodies and that's what I'm planning to run until I stop breaking things. I tried some Align white and red "Pro" blades but they caused the heli to vibrate a bit. I have a black set to try but haven't yet.

Apparently the Kasama head requires CF blades and I'm not ready to fork out $30.00+ for blades yet since I'll need them often. Then again, my instructor/guru thinks they are a good idea as they do not break as easily from small tip-overs. I'd have to really drive it into the ground and then more than just the blades will be destroyed. Only problem is if I have the Kasama head, I can't even USE TT woodies.

As far as the head, I'm thinking the best/easiest route might be to buy the Thunder Tiger metal head that the SE uses. I don't think it's head is available seperately yet but hopefully when I need it, it will be. I really want upgrade parts that fit/function properly from the beginning. I hate the idea of having to cut/file/bend to make something fit correctly. Too many years doing custom RC models I guess.

In reference to the Sonix parts, can you give me exact part numbers as I'm still having trouble finding them on Helidirect.

Also, why can't I find the Helidirect "deal of the day" stuff? I've looked many times around their website and can't seem to find it.

Thanks!

Dave D.

Status: offline 		I would skip the se head and get the kasama. For beginning, you really don't need the metal head yet though it might not break as often when you hit the ground with it. IMO you should be able to get by on the stock head though you may replace a part here or there.

Contact kasama directly if you want to find more info about this but I have heard that they will soon offer 5mm grips instead of the 4.5mm grips that have been standard with the kasama head up until this point. The red and white align blades you tried are the way to go with the stock head. The tt woodies did seem to track easier/better right off but you should be able to get the aligns to track as well also. You will need the TT spacers and I run them a bit tighter than I would the TT wood blades. You may have to make a slight tracking adjustment after installing them but if you simply cannot get them to track I would suspect another problem.

My MT has a funeral this week, I flew it on Monday and had some kind of failure that pretty much so totaled it. I was up about 80 feet or so doing flips and rolls. Ten backflips or so and a few rolls, then I started to pitch for a forward flip. As the heli came vertical (nose pointing at the ground) something failed. There was a quick snap/clunk noise and I lost all control. Could see the blades losing RPM very fast and flapping around. The heli stayed nose down like an arrow and fell all the way to the ground. Impact nose first, almost needed a shovel to get it out of the ground. I hit throttle hold to minimize the damage but it didn't really matter.

The only thing I found of any interest in the inspection was the two links going to the blade grips were popped off. I think one or both came off in flight (though when I popped them back on they still felt very solid). No damage to the Kasama head system aside from a slightly bent main shaft/feathering shaft. Gyro and servos are mostly out back so they survived. My ESC, CC BEC were both destroyed. Everything in front of the motor just crumbled. Motor mount plate bent 90 degrees. Frame is trash, boom is bent, broke one boom support. The radix blades survived, partially. There is a nick in one of the trailing edges but other than that they would have been ok. Trash now though I suppose.

I think the motor survived, and the battery was ejected on impact so that is ok. So much damage to the frame and the rest that its going in a trash can after I pull off the electronics. Funny thing, the heli never chicken danced but the main gear is completely shredded. The gear stripped in flight, or in the fall, when this happened.

Status: offline 		Well i had a crash today with my mini titan, broke the landing skids, canopy, bent the flybar and one of the blades struck and bent my tail boom, I was fling in winds up to 10 knots but i was high enough to make corrections, i flew the first battery and landed very smoothly, But the second battery did'nt go so well on the landing, i had a strong gust of wind slam it nose first on my landing approach , it was still fun while it lasted anyways parts will be in tomorrow

Status: offline 		Guizmo- set the AFRs as in the third paragraph above and you should be good to go.

Dave- yes, the Kasama is sized for 4-4.5mm grips, which means FG or CF blades. The Align 315/325 FGs work well for puttering around blades, and they're fairly cheap. All of the gray anodized aluminum parts on HD are the Sonix brand. Sadly, HD discontinued the DoD I believe.

Sorry about the crashes, folks. redvtr, it does sound like something malfunctioned in the head in flight. I had the pitch ranges set too high on mine and managed to bang the flybar levers against the grips (also doing flips, unsurprisingly). Mine didn't crash, but it sounds similar to what happened to yours.

Status: offline 		Osterizer,

After some careful inspection, I'm believing that is what happened. I was around +11 -10 or so from my best eyeballing on the pitch gauge. There are a couple marks on the flybar levers and a small mark on the headblock where it looks like the grip made contact. I found nothing else that pointed me to that thinking aside from the stripped gear before the thing ever hit the ground.

Its a wash, The whole heli is in the trash can. I was shocked last night when I went through the disassembly. Even my 401 took a whack. I had it mounted underneath the boom in the hole towards the back. In the crash, it broke free and went up into the tail drive. I suppose its off to futaba for the gyro. The servos are ok so thats a positive. All I have left of my mini titan now is the CF tail fin, the stock landing gear, and the kasama head. I kept the screws as well but everything else is in the trash can.

I suppose I'll have to pick up another kit sooner or later.

Status: offline 		Got my parts in today and i have my titan back together, I 've noticed there is some vibration on spool up but it stables out at mid stick, i'm guessing my main shaft or my feathering shaft has a slight warp to it ? or maybe even both, i have 2 spare main shafts and 2 spare feathering shafts, I'm guessing the slightist bend would cause it to vibrate, even tho it is'nt visible while spooling up.

You guys think it would be in my best intrest to just replace the main and the feathering shaft and be on the safe side ?

Thanks

You had the Kasama head on it? Wow. Interesting, though- I haven't had a problem with that one. My incident was with the original head. I'll have to recheck my settings before I go out and fly it hard again. Still a shame it got smacked.

Got it

The main shaft was slightly bent so i replaced it and now she's smooth as molasses again.

Status: offline 		redvtr100 & Crossfade,

Sorry to hear about your crashes.

I will look further into the Kasama head. My other concern is that the Kasama (or any aftermarket) head will require custom modifications to work. If they come out with one that accepts stock TT woodies that would be great though and I might try it. What is their website URL and who do you guys order them from? I would really prefer to order from a USA company.

Oster, it seems the stock TT woodies fly GREAT for me so far. I will try my black Align wood blades soon and buy some of those FG Aligns to try too though. The white and red wood Align blades made the heli vibrate even after balancing them so I'm just keeping them for emergency.

Update on the MT... I replaced the stock plastic mixing levers (after one broke and caused the crash) with TT aluminum ones. While she was bladeless, I spooled up and noticed quite a shake at low RPM. Turns out the darn flybar paddles were .2 grams different! I added tape to balance them and now spool-up was SMOOTH! (I now remember reading a review where the author said the flybar paddles were out of balance.) Then I decided to add another set of Align flybar weights (my instructor has 4 on his MT). I had one set against the paddles and put the other set about 1" in from the 1st one.

I also added the HRPoly X Visual/Audio Lipo Low Voltage Warning Device.

Took the MT out in the gym today, flew 4 packs great and the HRPoly alarm worked pretty well.

Now I just need to get a couple more batteries. I'm not too happy with the "top of the line" Thunder Power eXtreme V2's. I'm getting less time from 2 of the 3 packs after 12 flights than I did when they were new. The revolectrix pack from FMA however has been AWESOME! I plan to get a couple more along with another 4S charger.

Status: offline 		Glad the box blades are working well for you, Dave. The Align FGs are kind-of flexy for hard maneuvering, but they have a decent feel and still give a good pop from collective . The Align woodies I have are OK, nothing special.

Shame the TPXs aren't working out- I have a bunch of ProLites that I swear by, 1320s and 2100s.
