Status: offline 		I finished my test jig. It looks pretty good.

What it is: just two 2' long 2x4 pieces of lumber. Around these are these 4 'springy rings' I made from scrap iron clothes hangers.

The foam training gear balls just fit under the rings. One for each. Now then, there is no freaking way this heli could lift those 2x4's, but I put two more 1/2" boards across those! Suffice to say, we are totally anchored, but the rings allow for a few inches of movement. I really doubt the heli could tear its skids out of the training gear attachments, either. Let's hope!!

Ideally, I should be able to hover freely just an inch or so off the skids, but be unable to blade strike or move off the wood bars.

I'll take a pic when its ready. If this works, I'll recommend it for any Maiden flight on any kind of small experimental aircraft or any newbie looking to get a feel for the micro heli controls in the living room with complete safety.

Muhuhahahaaaa... * batteries charging *

Check out the pics!

What we have here is a Helimax dynamic test stand. It allows a couple inches of free movement for the aircraft in complete safety and there it is right in the living room, freakin out the wife!


What I learned

My settings were conservative - at full up stick I could barely lift off. Good!

I made lots of adjustments and came up with a new Throttle and Pitch curve that should allow for a tame platform to learn the hover.

I needed more control Cyclic control throw.

The EXP function helps tremendously, compared with the stock radio.

When I get this all dialed in, I will post all the settings. That should really help the next guy to try this. I thought a bunch you had already converted to DX6, but I guess I am one of few (I doubt the first!).

I have now confirmed that the heli is safe enough to try at the large clubhouse, on the smooth flat floor where I can hop and slide around enough to see if the vehicle is ready to hover! I really don't think it will get away from me!! I will conquer the hover is short order!! BOOYAH!!

Semper fi, carry on!

Status: offline 		instant carnage with my first flight when i ran into a wall. ordered new parts from tower hobbies and am ready to replace blade grips, flybar links, and stabilizer control hub. can anyone give me the "easiest" way to do all this? i've tried to unscrew the blade grips, but it seems as though heli-max torqued them in there pretty good...and used a whole bottle of loc-tite.

Status: offline 		Sharp eye! I made some makeshift flybar weights. The are exactly 2.2g each and seem to be too much... The head is still balanced and spins smoothly at all RPM.

I want that extra stability...

Status: offline 		Waksail17 Sorry about the crash

I don't know the best way to fix those broken part because luckely the only thing I've destroyed is a set of blades.

But you said it happened on the first flight so some advise on learning the fly is when you get the Heli fixed try to adjust the gyro if the helicopter wants to drift all over the place.

I just bought my Axe Cp (first heli) last week and messed around with the gyro, got it almost perfect, it helped me greatly. Now, five days later I can almost hold it in a steady hoover.

Status: offline 		This is why I'm going through the extra work - I don't wanna crash. I intend prove its an avoidable thing, by maximizing odds for success in every feasible way that can be thought of. Real heli pilots crash only in the sims - its just too costly to crash the real thing. And since the real thing behaves so differently than the sim (especially with my non-stock radio gear), I am taking this very methodically.

My approach is that this aircraft is a purely experimental and wild animal ready to spring off in a random direction the instant it has the opportunity. I can deny this opportunity and build up reliability of operation and control skill very gradually.

I plan on getting my hover down pat on the original blade set. Anyone wanna bet I don't have to buy another set? Remember, I'm a total nOOB at RC helis...

Status: offline 		Markind I wish you all the luck!! I had my AXE CP almost a month before I got Realflight G3.5, the sim is remarkably similar to the real thing. After the practice on the sim my hover was much more improved. For me the Sim paid for itself pretty quickly. Between the sim and hands on with my heli I can hold a tail in hover dead on, that is until she(my heli) decides to take a short trip and then I have to bring her back to me. I still crash, but a lot less often . I am working on my left and right side on hover and then NOSE IN!!
Don't get me wrong, I hope you never have to buy another repair part, that would be great but from my experience crashes are going to happen. It's part if the fun and challenge of flying a heli.
Ever see anyone scratch thier nose while flying a RC plane? I bet you never see that with someone flying a heli!

Must be lots of fake heli pilots out there in heli world crashing. Like Curtis Youngblood,Alan Szabo,Danny Szabo................

Status: offline 		Yep should've qualified that - real heli pilots do crash but its a very rare occurance. Very very rare because of all the safety procedures - checking and double checking everything - knowing what the aircraft will do given all the conditions.

That's great news about Realflight - I am very encouraged by this because I am getting in an hour or so of sim time every day, and now I can fly fancy circuits, dabble with inverted flight, and generally not crash while flying around casually with this sim model.

But the real thing needs to be treated like the space shuttle - and even that thing can crash and burn despite the best efforts of the best people in aeronautics.

In short - it will take some luck to be able to get to the point where I am comfortable with the hover and not have to replace parts. I'll maximize this luck by minimizing the chances for bad luck where ever its feasible to do so. The test jig really helps here: I have a good feel for what the model will do as it spins up to the point of lift off. Much better than going into the maiden flight like a blind date!

I hear your caution about this model wanting to leap out in a random direction and then need to be pulled in again. It's a twitchy bird going into this project, and here I am ripping out the stock radio... heh

But I figure the long term advantages in smoother control and enhanced safety are worth the effort to convert to DX6. Its a good feasible move in this case, and should increase the odds for success overall.

Status: offline 		I was just messin' with you about fake pilots. I hope your test rig helps you out. You will crash at some point but do not let that get you down. The stock radio leaves much to be desired. The news that Spektrum is making modules for other radios is good. Now I have the motivation to purchase a JR9303. Now if I could quit spending money on tattooing,homebrewing beer,DIY tube amps,DIY speakers,and my koi pond I would have that radio soon

UPDATE:

I reversed the blade grips, disconnected the motors, adjusted pitch, and was able to get it back to hovering* in less than an hour. Note to anyone though who might want to take those darn grips apart, the factory really did tighten those buggers up pretty good, and it's a small step between getting those screws out and stripping the heck out of those tiny philips heads and wanting to pull a 'HULK SMASH!' on it.

WOOO!

Thank you all.

*Note: Hovering, at this stage, was proof of vertical lift and proper throttle control. Me? Hover? Already? HAH. maybe in a month or so. I Just don't have the money to toss another 200$ into this for a sim at this point.

Rock on.
