Hmmm, one would think that a vendor would sell customers parts that fit and worked on the helis they sell, without the customer having to re-invent the process.

In an "ideal" world that would be the case..... You having to "adjust" your canopy to fit your needs is not unusual and not "unique" to QWW.....

As a buddy that's been in the hobby for a LONG time would say, "That's modeling " !!

My Posts This: Topic  Forum		When fitting a fiberglass canopy, it is not unusual for there to have to be some "tweaking" going on.....at least that has been my experience. Also QWW has some of the highest quality fiberglass canopies that I have seen, especially for the price.

With the newer Bat style frames all of the canopies have to be cut out on the bottom for clearance. I know that you have the older frames. So the cut out doesn't necessarily apply.

I don't have a problem with doing the cutting myself so that I know that I have everything just right. I guess QWW could instruct their canopy vendor to do this for you and pass the cost along to the customer.

If you put the canopy on straight and level, I bet the standoffs will line up outside of the window areas and will mount fine.

Another thing about having the heli designed this way is that you can put just about any aftermarket canopy on the heli that you like.

Have you ever bought a quality helicopter from a reputable manufacturer? If not, you oughta try it sometime. They sell parts MADE for their helis. Not one-off miscreants.

My Posts This: Topic  Forum		i hate having to drill, n place the canopys. currently my 3 helis dont fly with a hood on. only cause my 60n sport has a milkjug canopy and i would have to do some major cutting to get it off my align pipe ? my 500e doesnt fit well either as i would have to mod the batterie tray even with 2100 mah batts (which would be smaller then sugested) and i have yet to drill,N mount my logo canopy either. so there you have it, most dont drill the holes as every heli and electronics trays are different. how ever it would be nice for them to give you some dimples and say this is the spot if you go stock. i do think most after market canopys come drilled or at least dimpled

My Posts This: Topic  Forum		F6Hawk ,

I have....... and none of them have been completely "cut and paste" as you suggest.... Often times, for example, the MODELER has to trim the canopy for a "custom fit" depending on the type/style of muffler and/or other components that will be used.....

It the manufacturer were to offer a canopy for each and every combination available out there, we would not be able to afford their kits !!! It's just impractical if not impossible to do !!

I don't mean any disrespect to you, sir, but quite frankly, if this little MINOR issue upsets you so much then perhaps this hobby is not for you....

Good luck !!

My Posts This: Topic  Forum		Cut and paste... I DON'T expect. I have PHD in Heli maintenance, and I have to tell you, this is NOT the standard. Sure, things need some tweaking/trimming. But to wait 2 months to get something that fits half-assed.... well, IMHO, that is just wrong. I could see it if it just needed a trim, but it is more.

I will make it work, that is my lot in life. It ain't a lot, but it IS my life. I have to say though, if I were selling heli parts, I would inform the buyer... "These parts you are buying, they are a NEAR fit, not meant for your heli". BEFORE I sold them. Kind of like the boom clamps I was sold that don't fit, cuz they are for a different model.

Thank goodness I only paid for a used heli that I expected nothing about. I got what I paid for. My next one will be a Bergen. Quality DOES have a name, as well as expectations that go along with it.

Just remember to tell your next car dealer that you don't expect the hood to fit the car, or the doors to close completely. I'm sure you will get what you pay for.

My Posts This: Topic  Forum		Well, I didn't want to argue about the canopy any more until I had time to work on it, so now here we are. I cut the bottom out as suggested, allowing the frame to fit inside the hole. Trouble is, the standoffs are still in the windows. Looking at it now, the only way to ever keep the opening around the swashplate AND get standoffs out of the windows is to move the standoffs. Not sure if they will move where they need to, it will be close to the main gear shaft as well as the servo linkages on the left side.

Perhaps I will just remove the standoffs, and manufacture something of my own design near the back upper corner of the canopy, and drill some mounting holes near the servo.

Thanks for the ideas, guys.

My Posts This: Topic  Forum		Shuttlepilot, back when you mentioned headspeed, I assume you can do that because you have a tach installed? Alas, I don't... How critical is finding the headspeed? Shouldn't the gearing be such that it was correct when it was built? I know people buy different pinions and such to make changes, but I have only what was on the heli.

My Posts This: Topic  Forum		Well, it ain't the slickest job ever I saw, but it seems to work. Just not sure about the vibrations, but time will tell. Could not use screws on the back, had to fabricate using a brass dowel.

I guess this makes me a modeler, eh?

My Posts This: Topic  Forum		F6Hawk,

Outstanding ! Nice job !! I really like your method of using fuel tubing as a "stop" and to retain the canopy in place.... You have my vote on becoming a "modeler" !!

Regarding your headspeed question...... even though there are "on board" tach's, most of us use a handheld tach such as the ModelAvionics or Miniature Aircraft models......These units would require a second person present to operate the tach.....

The gearing will be correct for the size motor installed on the heli. If you were to convert your 30 to a 50, then the gear ratio would have to be changed to better use the motor's "power band".... Without that change, going from a 30 to a 50 would most likely overspeed the head.....

So, with what you currently have, the headspeed would be "adjusted" by increasing or decreasing the motor's RPM via the throttle curve. Without a tach , you would need someone with experience to help you achieve a decent headspeed..... I've been at this for a long time and can usually "guess" someone's headspeed within 100-200 RPMs......

I wouldn't go through the expense of buying one at this point, just have your friend Mike give you a hand with that.....

Ok, so what's my headspeed, plus or minus 400 RPMs?

Thanks for the info, I was reading about it and had some PM help that led me to this conclusion already. Hopefully Mike has a tach so we can dial it in. Thus far, I have only had it at about 50%, enough to get it to hover, but I guess RPM could be anywhere +/- 500, depending on the engine speed.

Thanks for the compliments on the canopy, it was fun getting there. I even sliced two VERY thin washers from the fuel line to use on the screws on the front of the canopy to protect it from the metal Here's hoping it works...

Nice Job

I would suggest you move your fly bat paddles to the front holes....
the machine will track much better that way.

That is our original 30 machine, I can tell by the machined-ball bearing washout links that we used before we made the mold.

It is a great flyer..Canopy looks great....QWW

If I survive a few flights, I may even opt to paint the canopy...

My Posts This: Topic  Forum		Well, the heli gods must be upset with me. Got the canopy done, cleaned out the fuel tank, added a kinkless clunk, and wanted to check out the gyro settings after watching Bob's video.... powered it up, only to discover my elevator servo is dead. Well, near-dead; I can move it by hand whichever way the TX is telling it to go, but it is hard to move it the other way.

Oh well, "say law vee", eh? I am off to the LHS to get a new servo or two, as well as see if they have a tacho.

My Posts This: Topic  Forum		Unforturnately, no.........

Those backing plates come as part of the kit....not with the servos...

You can just make some new ones out of a suitable density plastic. Just try to match up the material and thickness to what you have....

As an alternative, you could also use machined screws with washers and lock nuts to secure the servos..... But, that can be a royal pain in the neck to install due to the tight spaces between the frames....

PS-- Did you get that throttle curve stuff sorted out ?? I never heard back from you after my last PM.....

My Posts This: Topic  Forum		That is a nice looking canopy. Irwin, do you make a 50 size version of it?

I don't think we'll have much problem getting the head speed set. If we set it so the heli will hover at 4 - 5 degrees pitch, then it'll be pretty close. Or we can simply buy a tach (which I think we will do tomorrow). I've been wanting a tach for a while now.

Good thing you found that servo! It would have been very bad for it to go out while flying!

My Posts This: Topic  Forum		Well, things didn't go so well today. Not sure if it was a link flying off, or a piece of fuel line that I used as a flybar leveler during setup, but Mike had it running, said everything looked real smooth, and was lowering the collective when the heli pitched forward and right from the ground. Lost one servo link, damaged a blade, broke a servo wheel, bent the flybar.

Took it to the LHS, and they THINK the main shaft may be bent, but I know it was like that all along. If it IS bent, it's not by much, not enough to be discernible while it is rotating slowly, and Mike agrees that there wasn't any weird vibes going on.

So I bought all new rods and rod ends, will take it all apart to check the shaft, and rebuild it again. The good news is that we found a JR main shaft that "appears" to be an exact match, so if I need it, I won't have to wait for shipping from the US.

Gonna give this another go. If it fails to work, I will just scrap the whole project and get a gasser or a 90 class.

Didn't even get a chance to tach it, and when Mike got his 50 in the air, I was so enthralled watching him fly I forgot to pull it out and try it. Newbies! But it was great watching him fly. He said he was nervous, hasn't flown in months, but I thought he looked like a smooth operator. He was prolly just saying it to make me feel good.

Thanks for the day, Mike, for taking the time to drive an hour away to offer your help, thanks for the extra gallon of fuel, and I hope your move to the US goes smoothly. Holler at me if you need me to mail you some kimchi!!
