Tiger 50 canopy
Hi, I have a Tiger 50 that is collecting dust.. I intend on making it electric, but I have several questions, can I use a pantera canopy in the tiger?

Also, is there a way to make it a 700? I want to buy a flybarless head, and would like to stretch it to 700..

Alejandro,

Yes, the Pantera canopy fits the Tiger 50. This is because I was very careful to ensure the mounting dimensions remained the same. Frankly, my desire at the time was to make it as easy as possible on my customers despite the dramatic changes when I updated the product (enough so that it became an enirely new product since the drive train changes necessitated a complete change in the side frames, as well). However, for these same reasons, the electric conversion we offer for the Pantera 'also' works on the Tiger. Similarly, so does the 700-stretch conversion. Anyway, below are the part numbers for Stage I or Stage II electric conversions as well as the numbers for the longer boom and belt.

Stage I: http://www.audacitymodels.com/Produ...16/Default.aspx
Stage II: http://www.audacitymodels.com/Produ...26/Default.aspx
700-boom: http://www.audacitymodels.com/Produ...F7/Default.aspx
700-belt: http://www.audacitymodels.com/Produ...-2/Default.aspx

Note, however, both the above e-conversions are for motors with a 6 mm shaft but we offer them for motors with a 5 mm shaft as well. Also, we're working on a 700-class flybarless head. Finally, while I hope this information helps guide you, if you have further questions, please contact me directly.

Yes, that head will work fine. However, you may wish to experiment with the RNFBL conversion instead. Why? Simply because it flies just as well and by repurposing standard Pantera head components (along with some special long M2 screws we sourced to accomplish the task) costs virtually nothing. Many have done it and it works beautifully.

And don't take my word for it because a review of this very inexpensive conversion was recently performed by Sikorsky engineer Dr. James Wang (in a the April issue of Model Helicoper World magazine). Also, retired fighter pilot, Paul Tradelius has writtten about it in his column within Model Airplane News magazine.

Anyway, this is proven way to get an FBL head, which costs nearly nothing and works very well. Thus, unless your money is growing on trees, it's worth trying. Here's the link to how it's done: http://www.audacitymodels.com/Produ...53/Default.aspx

The herd isn't always right and thus, just because it's not mainstream doesn't mean it isn't a good idea. This really works!

And John, I want to swing 700 mm blades, would the Tiger 50 head be capable with the RNFBL?

700-class blades weigh significantly more than 600-class blades so the answer to the question is - not at 3D RPMs. However, the upcoming 700-head will, of course, because it's been envisioned from the beginning with 3D performance in mind. Anyway, I slip a set of 700s on the smaller head all the time - but expressly for farting around only - like for shooting autos because I am careful to keep a close eye on operating the head at lower RPMs. However, thusly equipped, the model simply floats down . . . seemingly as slowly as a mapel leaf and is, quite frankly, loads of fun.

Not planning on using it for 3D, would like to fly it at max 1700 RPM

I hesitate to ever recommend RPMs, so you're on your own with this because it's outside the design envelope.

That said, if you're mindful of what I am saying and only fly it with low-ish RPMs, you should be fine. As an example, I fly and shoot autos with my Tiger 50 (using the MkII head, which is to say, the Pantera head featuring a 6mm spidle) at 1450-1500 RPMs and have never had an issue. Also, because a 7 pound model is a lot lighter than the typical 700-class bird, the performance at these relatively low RPMs is quite good (some might even say spectacular). Anyway, I only give the model +/- 7 degrees of pitch, hover it at about 4 degrees, and get simply great performance.

Regardless, be mindful of what you're doing and always keep spectators, children, and pets away. Moreover, always hover the model a prudent distance from you and with the main rotor blades above head level, especially while you're becoming used to it.

One final caveat; just because the grips of my model haven't failed doesn't mean yours won't (and quite frankly, I never really trust any model helicopter - not even mine - and neither should you fully trust yours). I'm just saying.

John, one last question, how does de LSD works on the Tiger? I want to have control over the tail.. or could it be possible to put the autorotation hub of the pantera on it?

The different spacing of the shafts precludes the use the Pantera drive parts. This is related fundamentally to the redesign of the Tiger drive train, which led to the Pantera in the first place. Anyway, the LSD works just fine and will quite nicely do what you want, e.g. drive the tail rotor when the engine is off. This allows you to steer during autorotations, which is what you're wanting, right?

Regarding the autorotation hub, the Tiger and Pantera share the exact same part, which exists for a completely different reason (having nothing whatsoever to do with what you are inquiring about above). This means the AUD0032HD autohub fits your Tiger as well.

It attaches below the main gear. Just remove the Jesus bolt, put the LSD in place, replace the bolt (the hole in the LSD is slotted and thus, you can adjust the tension for driving the autohub during autorotations). The downside to the LSD design is it drives the clutch bell as well, which absorbs a tiny bit of energy but since the clutch shoes aren't engaged it's a trivial consideration. I, quite frankly, thought this was a perfectly acceptable design compromise but the market (Raptor owners at the time) said otherwise. Believe me, it is a nice way to accomplish the task (from an engineering viewpoint because it greatly reduces complexity and parts count). However, consumers, e.g the modelers (who aren't engineers) always have the final say. Thus, I redesigned the drive train to do it the way they wanted. In the end, it was machts nichts.

So if it drives the clutch bell, and I'm doing a electric conversion, I must use stage 2 right? because if not, it would drive the electric motor....

With an electric, there's really no concerns about autos because it's not like there's an engine, which may die. However, yes, if you want to retain the ability to practice autos, the stage II would give you that bonus with an LSD.

No way would I bother converting a Tiger to anything. At least start with a Pantera. I had two Tiger 50's and they hold the distinction of being the crappiest helicopters I have owned in 20 years of R/C heli flying. The Pantera is a much better starting point. I put an RJX flybarless head on mine. It is a bolt on fit. It would be a good starting point for converting to 700 but if I was going that route, there are way too many good 700 size helis that I wouldn't bother trying to convert a 50 into a 90 size heli.

I find this a rather harsh judgement of the Tiger 50 because I continue to fly one and far from being crappy, it's a fun and relaxing model. A lot of folks agree too, which is why we support it with spare parts going on 6 years since ceasing production!

Meanwhile, a 700-conversion is an inexpensive way to play around with the benefits of a larger model (they are universally judged to fly better) without significantly increasing your crash costs. Especially because you can do it while repurposing your existing investment in equipment via a quick upgrade of the base model. Seems a lot of pilots end up flying more model than they can afford to crash (have you checked out tail boom prices for a Goblin) for reasons, which elude me.

Is it really because they're sheep buying the hype of others, or do they actually believe eating Wheaties means they'll performance like the guy pictured on the box? Regardless, mental masturbation explains it neatly.

Happiness isn't having what you want, but wanting what you have!

I think it's fun to take a semi-retired bird and change it.We have lost way too many guys because of the cost trying to keep up with whatever is new.There is no fun in crashing but the fear of it because the price is too high is very damaging. Experimenting and changing is really more fun than you might think. TimT

That's a very astute observation Tim.

I occasionally see what I think you're speaking of at our home field where newbies sometimes show up with $2000 worth of 50-class heli. And incredibly, these are models for them to begin learning to hover!

As a consequence, they're mentally a mess and it's entirely due to fear of destroying their shiny new toy. For example, I've many times overheard them say things like, "I've gotta be careful because my wife will kill me if I crash it." Or, "I can't fix it until after I make my truck insurance payment." E.g. they're basically flying models they really cannot afford.

And if you think about it, a newbie buying the most expensive model available is akin to buying a Formula 1 race car with which to take driving lessons. And it's especially sad because there are no bad models on the market (they all fly well) and it doesn't matter because they couldn't possibly tell the difference between the most and the least expensive the market has to offer - not yet - and many will probably never be able to tell the difference!
