e-HeliDirect Outrage - HDX 300-600 > HDX300, continuing saga

So the HDX300 is going back together, slowly but surely. I start to check out the servos for centering and begin to make new links last evening. Hmm, no tail rotor control. Plug the servo into the receiver and the servo is OK. The darn E-Flite HH gyro is toast.

Even when I think I'm getting it back together, I'm still finding broken bits and pieces on this heli.

Worst crash I've ever had with a heli and I never even left the floor! Dang!!

Mastic, I needed that smile. Thanks for the boost. It's the stubborn Irish in me. I refuse to let this little monster get the better of me. What bugs me the most is that I had it flying pretty good on my composit mainshaft. I popped a V3 shaft into it to get back to back flying impressions. BIG mistake!

Today's project will be to start making new link sets. I hope to get it flying again in a couple of days

With the new V3 out, I think that all of us that dealt with the V2 and made it work with all its shortcomings should get a free V3. We've spent that much in parts. Or at the very least we should get one heck of a discount on a V3.

What do all of you think?

I wonder what version I have considering I just got it a month ago from helidirect? And my saga continues also...I finally got the proper drill bits from DrillCity and 4 bits broke but I got a hole drilled and I FINALLY got this headache together and started to fly but dam what a handful..this hdx300 has very slow reaction to my inputs,I dont know if its my crappy micro servos or what plus I even put in positive expo on my 9C. I havnt gotten any weight for the flybar and I guess that helps alot? man I got so many questions but thanks for helpin with these .

To my knowledge, the V3 uses a different airframe and lipo mount.

As for lack of response, that is one issue I haven't had. You might want to check out your head setup. I found that the T-Rex 450SE head setup instruction quite helpful. Certainly not for link length, but for overall setup.

I run flybar weights on mine as well as expo and dual rate on pitch and roll axis.

I completed the head link setup this evening as well as installing a TeleBee 6G HH gyro. The E-Flite HH gyro that was installed on this heli is toast. There was no apparent impact damage, so I have no idea as why that failure. I hope to have it airworthy again in another evening or two.

Thanks again Gerry ,,yeah gyros cant take alot of beatings and my 401 im using is taking tons of it ,I crash everytime I fly this 300 but I luv the way I pick it up straighten the flybar and im flying again. So the flybar weights keep the heli more stable? I need that. but yes I cant understand why my responce is so slow ,it must be my generic Futaba servos. Paul

back in the air!

After a long rebuild, my HDX300 finally flew again this evening. All went well, with the need to complete blade tracking, flight trimming, and fine-tuning the gain on the TeleBee 6g HH gyro.

There are some setup changes. The little $6.00 servos are working great. Quite surprising! I've used the little TeleBee gyro on other helis. The setup and gain on this gyro is slightly different that the E-Flite HH gyro that was damaged in the crash and replaced. The mainshaft that is currently installed is one of my own stainless steel/carbon fiber composite shafts. I've NEVER had an issue with one of these shafts and as such will NEVER again use a stock steel shaft on my HDX300. This is regardless of how "hard" replacement shafts are touted as being.

I hope to complete the final tweaking tomorrow evening and have my HDX300 back to full flight status.

Funny, in a way. The one-way bearing is probably the only item on this heli that I haven't had problems with.

All flight trimming is completed and the world is now fine. My HDX300 is once again in fine flying condition.

There have to be others that have worked through the difficulties with the HDX300 and have a good flying little heli. The issues with the soft mainshafts have been the biggest hurdle. The mainshafts made from injector pins seem to solve that issue. The remainder is just carefull setup and adjustment. As you might notice from my more recent photos, I've raised my heli 10 mm by inserting spacers between the landing skid legs and the frame.

I hovered through three LiPo packs this evening. It's running dead-true with no vibration or runout. My one remaining chore is to paint up a new canopy.

The other issue is to keep monitoring the performance of the cyclic servoes. I have a S75 on the tail. No idea as to the origin of the cyclic servos. While they were very inexpensive, they appear to be no worse than the S75's I was using.

As for my composit mainshafts, plans are in the works to release them as a commercial product. I have plans and hopes to become a RR advertiser when all is ready.

ON AND ON AND ON...So I get mt new one way gear and I also got the blue smaller tail gear which I thought would be bigger put it all back together and go outside and NOW the tail shaft bends .Ok its the original stock one sooo now its time to use my injector material..Gerry I got a new tail shaft from helidirect in this order and its way to big but the pkg says HDX300TPY ,,,what is it? Does it fit a different tail case? plus how do I get the pully off the old shaft to use on my injector rod shaft i cut? Thanks Pal

not good quality,but here are some pics of what i did.
stock hdx canopy had that horrid imho hump on top which made the canopy appear very short and ugly.i ran some ca in the seam to seal it up,and put it on my belt sander.went down past the rivet keeping a sloping curve to it.
to me it now has a much sleeker appearance to it and really fits the look of my heli.plenty of battery room and great space around links so no quetion of link binding.
plus here is a pic of another guys build shows the old shape and how low it was with the bottom battery mount.

Mastic, to my knowledge, the hardened tail shaft fits the narrow tail box. There are two tail boxes. The older design uses two idler pulleys. The newer box is narrower and uses only one idler pulley. I did make the change a while back. So far, I've had no issues with the narrow box and hardened steel tail shaft.

From examining all the failed components resulting from my recent "incident", I believe it all started with a failure of one of the short link that run from the blade hub down to the mixer arm. This allowed the blade to flip. The resulting aero and mechanical imbalance caused the very quick destruction of the heli.

For year in racing R/C cars, we always boiled our plastic/nylon components. This removes the brittleness from the plastic allowing it to survive impacts and/or bending without cracking. I've started doing this with my heli links. Certainly can't hurt and can only help. At worst, there will be no change.

Regardless, my HDX300 is flying quite well as of this writing. As a matter of fact, I'm off to put a couple of packs through it this evening. Bye for now!

Oh, cool canopy, Aristo!

well my latest dilemma is my 401 gyro just wont hold , how much vibration makes the 401 not hold because my tracking is out a little because I never used a pitch guage and I did it all by eye,,,but a guage is in the mail. Also what is the strongest known adhesive ,I need to glue my canopy mount back on and I had to drill out the broke off screw part out of the frame and now its not threaded. Thanks Pals

Eyeballs just won't cut it, as you know by now. A pitch gauge is the way to go. If your vibration is excessive, I'd also check blade and paddle balance. Does your head spool up without runout? Also, you can have your blades too tight as well as too loose.

The mount you've broken off should be replaced. If you still have the broken threaded section in place, MicroMark has miniature screw and stud extractors. This is a great tool set to have and has saved my behind several times over.

The only 401 that I'm flying is on my T-Rex 450SE. I've had no issues with it at all. The only gyro failure I've had was with the E-Flite HH unit. This was installed on my HDX300 and was fatally damaged in my "incident". I've replaced it with one of the little TeleBee 6g HH gyros. This little gyro is working well.

well well well

I got my pitch guage in the mail and I really didnt even need it ,I had everything right where it should be but it was nice to see what my pitch was at mid stick. Buuuuut whats up with this wobble ? I can hover with medium headspeed but when I hit idle up 1 which is 100,90,80 ,90,100 and my HS gets up then I get the wobble of death .Now I have no clue what the HS is because I havnt tached it but it doesnt seem like its blazing fast. Gerry you got and help for this one? My flybar is nice and lined up good with the paddles and my main blades are the carbon ones from Helidirect and they weight the same on a scale. Im lost

Sorry about the delay in answering. I've been putting a bigger motor in our showcar, getting ready for our last big show of the season.

If I understand you correctly, you are true and vibration free at lower main rotor RPM but pick up a wobble at higher RPM.

If the wobble is circular around the main shaft, I'd check the side-to-side measurement of the flybar. While the paddles might be the same weight, if they are not equidistant from the center hub, you are still going to have a dynamic imbalance.

If the wobble is primarily up and down, then I'd check the balance of your tail rotor blades. You have checked their balance, right? LOL.

Thx Gerry , yes my flybar is exact , but no I did not balance my tail and did not balance the heli plus I did not use the tail boom struts. I am using a TP 1350 battery and a 401 gyro I have mounted on the tailboom as for the helis balance it does seem to be tail heavy..I guess I can move the battery forward some and I did not balance the tail either. The wobble of death as I call it starts at around 75% stick just after I get in the air and it definatly seems to be just in the main rotor. Im so pissed at this heli I almost want to just put it on ebay and be done with it but I cant admit defeat yet. HELP!!!!!!!!!!!!!!!
