RE: Blade 130X wobble
I just discovered another little tidbit of info. I took off my CF tail boom because I'll be replacing the tailbox with a Rakon heli upgrade. To my surprise the tailboom was completely split in half almost 3/4 the length of the boom from the tailbox end. I would surmize that this would be a major source for tail wobble. I have no idea how long it's been like that. The tailbox was literally holding it closed. I never could even detect a hint of that by looking at it when it was assembled because to me that dark CF can hide a crack. Better start wearing my reading glasses when inspecting this heli I guess. I'll pick up a new boom this week.

RE: Blade 130X wobble
New update: My tail started to jitter back and forth violently during a recent flight. I replaced C and D gears along with new metal A gear. I made sure that the tail boom was adjusted so there would be minimal slop between gears and it still did it. I was up against a wall trying to figure what it was. I put it into a hover next to me and observed the linkage rod vibrating back and forth in a rapid manner, so I took off the recent new tail servo that for a while corrected my earlier problem(with no crashes), and I replaced it with my supposedly bad servo ( I kept it just in case). I spooled it up and the tail was rock steady. I put in two more flights to make sure all was well. No problems. Go figure. Since there were no crashes with the new servo, I'll probably take it back to my LHS to see if I can get a new replacement and keep it aside just in case.

RE: Blade 130X wobble
Thanks, and I know what you mean. 30 years ago during the dawn of the new 'Cricket" heli that some people had at the flying field and was even at that time outside my budget, I remember mentioning that it would be neat if someone invented a palm size heli that you could fly in your house or small yard. Some pretty much scoffed at the idea saying that it would be an impossible task to miniaturize all the components needed to make it happen. Electric flight in general was very limilted then. Witnessing the advances made in this hobby since then are incredible. On the gyro, I went ahead and decreased the yaw(rudder) gain by four points and it stopped the tail from trying to overcorrect itself,something I see referred to as "tail wag". Despite the critisizms that I've read (and some of them have merit), I think these little machines are great learning tools for people like me that want to advance into CP helicopters after flying the 120SR. I've read arguements that their price point might be high for what it is, but being that I dumped it into the ground about seven times, I know that I would have been shelling out at least the equivalent cost of the 130X in replacement parts on a 450 size helicopter by now. I've greatly improved since then and have been flying cicuits around my front yard and actually did my first inverted on idle up mode. Not a big deal, but a big advancement for someone trying to learn coordination skills needed for flying these neat little guys. Take care.

RE: Blade 130X wobble
The problem has been solved. I went ahead and put my old gear in and flew it. Couldn't wait. Still shook around like crazy which means the tailbox treatment didn't work either, so I decided to go to another HH stocking LHS that I've done business with before. He turned on the Tx and heli and waited for it to initialize. Worked all cyclic controls okay and we noticed that the tail servo was acting a little hesitant. This time he disconnected the motor after turning heli off and then reinitialized it once more. Tried cyclic controls again. They moved a short distance and then FROZE. Wouldn't move at all with input. He said that on these analog linear servos that if you have one giving you a problem, it will affect the others as well. Kinda like a cheap set of Xmas lights. I didn't think it could do that. He suggested a new tail servo, so I went ahead and put out the 16 dollars for a new one and went home and did some remove and replacement. Put in a fresh battery after installation and powered it up to check all functions. I went ahead and lifted it into the air and now it's hovering as smooth as silk with absolutely no in flight vibration whatsoever. So this analogy can be added to the list of possible causes for in- flight vibration problems as well. I'm just glad I didn't have to ship it out to HH. I did have some small mishaps in thick grass before and I would guess that the tail servo got damaged in the process. Nonetheless it's working fine now.

RE: Blade 130X wobble
Actually, based on the advice of my LHS owner, the grommet swap was the first thing I did when I got the heli. Like you said, I just substituted the o-rings for the canopy grommets to eliminate the play before I even did my first flight a couple of weeks ago.

RE: Blade 130X wobble
I'll see what I can do. I just ordered one of the new optional metal tail gears if for no other reason just to have a more resilient gear. Since it's apart I'll wait until Tuesday when the new gear arrives and put it in. One thing that I did this afternoon was notice that on the tailbox, I was able to push it in a little further to seat it into the boom. I've read about this occuring with other owners, so I put a very small dab of ca glue on it to keep it there. Hopefully that might have solved it. The wobbling was not a tail wag or spool up vibration, it was the entire copter shaking while in flight every five seconds or so. It did it in both normal and idle up modes, whether it was hovering or in forward flight. You could see the landing gear shake side to side a good half inch during some of the worser ones.

RE: Blade 130X Upgrades
Any idea when your Hughes 300 kit is coming for the 120? It could probably be retrofitted to the 130X

Blade 130X wobble
I've had my 130X for about three weeks and have been doing mild circuits around my yard, being this is my first CP heli as a step up from my 120SR. I've had a few crashes into soft grass and aluminum siding, but generally besides the vertical fin snapping in two, nothing has phased it. Recently I've been noticing a wobble that happens about every five seconds while hovering and forward flight. Sometimes it's mild, but sometimes it can shake much more significantly. I went ahead and inspected my main shaft and found it had a hairline crack. I thought this might be it. After a new mainshaft, along with a new main gear and feathering shaft unit installed, it's still doing it. All my other gears are fine. My LHS owner inspected it and even flew some 3D with it and said this is normal, but I know that it isn't, as I did not have this problem when I bought it, and I don't see it happening in other 130X videos being posted these days, even after they have crashed their's. Any experts out there have any clues as to what it might be? Both main and tail blades are new, so that can be ruled out also.

RE: 120SR I has 1
Hi. First post in this forum. I too bought the SR 120 and the UM T-28 about a month ago. I think the 120 is a great little heli. Even though I've been flying here and there since the early eighties, I just got into the "bind and fly" stuff recently and really like it. I started out with a Team RC three channel heli for about thirty dollars and went straight to the 120 afterwards. I've been flying outdoors at dusk here in Southern California and have been flying over my house a lot practicing forward flight and nose in hovers into the front yard. I have a DX6i with the new DSMX technology and was thinking of later getting the new Blade 450 BNF as it comes with the new 6115e receiver and start to slowly train on that day by day. I've read that the electric tail motor on the 120 is fine but when you step up to the SR it has to work harder at counteracting the torque and wears out sooner, so I'll step up to the 450 since that's the size I'll probably stop at due to budget constraints.

RE: Assistance required...
Hello. First post here. You're not alone Kodiak. I'm 53 and just got into EDFs myself, and electric flight in general. I bought a JPower T33 in kit form from Toysonics before practically everything went out of stock there so I could use better electronics. I could have saved more if I got the ARF version but I wanted to use my own tried and true units. I installed a Hitec 55 servo for the elevator and two Towerpros for the ailerons. I've had a few of these on hand and have never had a problem with them. ESC is an EMAX 25 amp unit along with program card to make things easy. With free shipping and great service from Hobbypartz in L.A. county I went with Sky Lipos and got a few 1000 mah batteries to try out before I use a 1300. the 1000's seem to balance the plane very well while the 1300 puts it nose heavy. But I'll try it later nonetheless. Deans connectors on everything. After selling an eleven year old Hitec radio along with some misc O.S. and K&B motors and supplies that were about 28 years old and NIB, I just went out and bought a new DX6i from Evolution Hobbies here in Redlands,CA that has the new DSMX technology along with a 6115e receiver. I have seen these used in other planes that have been taken out to surprising distances for what is termed as a parkflyer receiver. I'm new to computer radios and all I can say is that I think the technology through the years has just made this hobby better. After I get around to doing a maiden flight I'll post pics and a review from a newbie's perspective.
