My Scale MD 500E
Finally got out today for the 1st test flight after changing rotor rotation. My friend helped getting the settings set up. I let him do the testing as I don't want to have it go in!! But got it just off the ground when the main gear stripped. And of course I didn't bring a spare. So will have to take it home to change out. I also had to strip the paint off the main blades as the color scheme was backwards now. Will work on repainted them this week!

Got a new main gear in today. But not sure what is going on, the new main stripped as well.

We had a bad batch of pinion gears a few years back. While I wouldn't think this is the problem because we handled all the complaints at the time, why don't you send me yours for inspection? If it's defective, I'll replace it for free (and replace your spur gear while I'm at it). Meanwhile, since you'll be pulling everything apart anyway, you can double check for anything else, which may be causing the problem. Please don't respond via PM and instead, contact me via email (or give me a call) and we'll coordinate. Fear not, I have your back pal.

I just got this new clutch bell and pinion from you in October or November after the pinion came undone. That was because I had the rotation going CCW. Sunday was the 1st time flying since changing to CW rotation.

And thanks John, you have excellent customer support!

I know exactly how you feel. Mine has done the same thing (different chassis though) but at least yours was only inches off the ground when it let go. I have much heavier gears on the way and the smallest pinion I can get. Hope the new gears sort this out for you.

Got the airframe out tonight to figure out what was going on with the stripped main gears. Well, I figured it out. The mesh is WAY OFF!!! My option for the upper pinion bearing turned out not to be such a good idea. Too much slop. So I have to order a new frame now. Last fall when the phonon backed out from the main going CCW, I cut up my spare airframe for the upper pinion bearing block.

So I will look at doing the P6 airframe I hope. Will have to call John and talk about it.

Also found my clutch piece that goes on motor was a little loose as well. I even made a second flat on shaft so it would be stronger. I used red loctite on set screws. Don't know what else to do on that problem.

Well, just ordered a P6 frame and bearing block from John. So hopefully I can have it back together by next weekend.

Well finally got the new P6 airframe swapped! Now my gear mess is WAY BETTER!!! So hopefully no more stripped gears. Will do a test tomorrow if weather is good. Spent about 4 hours to get it all together. Had the frame all together and forgot to put the pitch lever in, DUH!!! I lock tightened all screws that went into metal. I even added nuts on the motor mount plate. I hope this bad boy flies nice now.

Its late now, way past my bedtime. So till next time..

Don't feel bad, despite designing that helicopter . . . I've done it too.

Went out to the hanger today to do a little photo shoot. 1 of the City counsel members came by. He loved it! I told him I would like to sell it to the City, as I am not a good pilot, and it would look awesome at City Hall!!. He will think about it. Hehehe.

We were going to do a hover with both heli's. But I fat fingered the throttle hold without realizing it. So they had to leave. Its a good thing because when I did figure it out and was going to do a hover for the other guys, the horizontal tail piece came loose. It caught the tail rotor. So will have to make a new end piece and a little body work. Oh well, I am going to plan on doing the seats and some other detail work.

Aw, that sucks. Just as you have it looking like the real one shrunk, too. Hope the repair goes quick.

I've followed your Pantera scale-build with great interest because you're one of only a few modelers to have chosen to base a scale build on my product. This, despite scale being one of the Pantera's priciple design goals.

Moreover, as both a model and full-scale pilot (I've even got 1-hour of logged right-seat time in a Sikorsky S-52), I know what you were attempting to accomplish (getting photographs while hovering both rotory-wing aircraft at the same time) is much harder than folks may appreciate. Anyway, I also hope you get the repairs done quickly, and that beyond finding time to add some of your planned cockpit details, you'll also bring it to IRCHA because we're attending this year where I hope to see your work in person.

By the way, don't look for our commercial presence at IRCHA, e.g. as a vendor because we pretty much attend fun-flies only as modelers. This is because like the rest of you, we work hard enough during the week and while we're happy to show what we have, our real goal is meeting and greeting fellow modelers (regardless of the brand model they're flying) and enjoying the fellowship of the event.

Finally, let me add this . . . attaboy!

Thanks John. I will try to get the repairs this week.

I am VERY impressed with the new P6 frame, LOVE IT!!! Like I said earlier, I don't have that resonating sound I did before. I can't wait to start getting some flight time with it!!

I am pleased you like the new frame design. As you know, my history is of making gradual improvements. This time around, a key refinement involved making the bearing block above the motor removeable (as are the 5 others). This opens the door to future enhancements vice gear changes. Also, you may recall we made two iterations of the Tiger 50 frame set before finally making a clean break with the past and retiring the design in favor of the radically different Pantera (though we still offer Tiger 50 spares 6 years since ceasing production).

Anyway, this is the first major update to the Pantera side frame set and quite frankly, at present I really don't know what else I can do to improve it (though, as usual, time will teach us). That said, I don't see any weaknesses, e.g. where beefing it up would be of realistic benefit. And while making it lighter is easy enough, it would comes at the expense of durability, which I don't think customers would willingly sacrifice.

One thing I have been considering is offering a carbon fiber side frame upgrade (because it could be much lighter and far more rigid, which is of benefit to 3D customers, who far outnumber scale and sport modelers). But for scale, the plastic is so much more forgiving it doesn't make sense to me. Not only is our plastic much more flexible, which makes it tougher and more durable, but it's also significantly less expensive to replace side frames when they do break.

Frankly, other than a modest benefit achieved by reducing weight (again, great for 3D customers, less so for scale customers when the deficits of carbon fiber are taken into account), I fail to see whare scale modelers benefit. For example, CF is so much more rigid it breaks more readily in a crash (recall the children's fable regarding the mighty oak versus the flexible willow during a storm). What's more, CF more readily transmits vibrations (versus damping them) and worse, it's more critical of misalignments or any small imperfection in builder technique. Moreover, it's also more difficult for builders to modify (plastic readily cuts and glues very nicely), plus carbon fiber also has issues with shielding receivers from radio signals. Nothing which can't be overcome, of course, but why make life harder?

Regardless, 3D customers want carbon fiber (and they far outnumber scale customers), so it may not matter what I think. Thus, I suspect I'll ultimately end up offering the option. However, in a scale model, especially, I continue to believe the engineering-plastic we use (fiber-filled Nylon 6,6 like that used in Glock handgun frames) is a significantly better choice principally because it absorbs vibrations much better. Thus, if your model has relatively fragile scale details, like antennas, wipers, steps, brake lines, as well as pilot figures, instrument clusters, etc. this may be important to you.

Anyway, once again, it's nice learning you appreciate our efforts.

What mechanics is the heli is it a 500 or a 550? 600?

The mechanics are 600-700 class. It's a Pantera P6 from Audacity Models, which is basically a 700-size model being marketed as a 600-class helicopter. Thus, with the stock boom you may install it into a 600-class fuselage and with the extended boom, you may slip it into a 700-class fuselage. There is also an electric conversion available. Anyway, we're a Florida company located 350 miles away from you (in Sanford, FL, which is on the north-east side of Orlando).
