Hey Y'all...

 

Just got my second bird, with two more on the way...these things are addictive !!!

This is great fun while trapped indoors by the sub zero environs in which I choose to live...

 

So far my favorite is a 109G that looks a lot like this...chopper (that's me @ the controls)

 

I spend most of my days building cabinets...a cabinet shop is a great place to fly, with 20' + head space. The only downside is the constant sawdust in the air.

 

I did a mod that I haven't come across before, not that I've done a full perusal of everything on the web with regard to these little spinners, but I have been lurking for a time, & haven't seen anyone else post about it.

 

I used Scotch magic tape (like used to wrap X-mas prezzies) & made a tail rotor sandwich by putting the rotor blades between two layers of tape that stuck to itself when folded, making the blade HUGE.

Then I trimmed it with a small scissor, until the blades were about 1/8" larger on the leading & trailing edges, & also the ends.

 

This really seemed to help with forward momentum. 

 

I then did the same, to the trailing edges only, of the main rotors. So far, I've only noticed a little imrovement in lift, with no appreciable decrease in flight time.

Thanks for the welcome...double-thumbs-up-thanks-smiley-emoticon

 

After a few more flights, I've noticed no improvement in reverse, which seems kinda odd, as the blades have nearly twice the surface area...sco_hmmthink

 

But still, with the 109, any improvement in fwd speed is good.

 

Also, when the leading edge of the main rotors gets a little chewed up (for "whatever" reason..embarassed), I smooth em out with an emery board, & tape that edge so it's smooth again. Dunno if it helps all that much, but I think that at the very least, I might get some "placebo effect"...wink

I posted pics here, but they're kinda small.

You can still get a good idea of how much surface area was increased.

HA...it looks like somebody thought of it before me...check out the linked pics.

dwntgrnd says:

I’ve tried all of the speed mods including the flybar. The newer flybars make it impossible to remove weights without cutting plastic and throwing out of balance… But I did come up with a different mod that I haven’t seen anywhere else and I wanted to share. I’m surprised no one else has posted this. Or at least I haven’t seen it.

The Picooz tail rotor blade was disappointing for all of the trouble (finding, purchasing, inverting motor, etc.) It didn’t give me the improvement I hoped for. However it did inspire me to try making one of my own. It turned out to be one of the most effective and simple mods I’ve tried. In fact, if you do only one mod at all this should be it. All you need is some masking tape or painters tape and a pair of scissors. Simply fold the tape over the stock tail rotor blades and trim to shape. The added weight is negligible and it can have a dramatic impact on acceleration and cruising speed. The best part is that you can experiment with different sizes, shapes and curves. Fun stuff. (Hint: If you extend the length of the blades too much the thrust gets countered by main rotor downwash. Best to keep to stock length)

Here are a few photos. Not very good but you’ll get the idea.

I own a few 107s so I like to try different mods side by side. I always keep one stock for baseline comparison. This is the best mod i’ve tried yet. Especially when combined with other mods. I may post some video someday when I get around to it. But I wanted to share this and get it out there. It’s a great mod and I haven’t seen this posted anywhere. And it’s super easy to do. Have fun!
