It is very interesting to see the evolution of products especially in this realm of the RC hobby so its the reason for this topic.

I received an invitation, from this forum, via Email, to post here, so I thought I contribute this thread. Hope it is as interesting for people reading it ,as it is for me writting about it.

I recently bought a PiccoZ because the use of IR, as a form of control, caught my attention.

Before there were any micros on the market I had designed a heli called the Robin IR back around 1996, which used IR for control instead of RF. I made this choice because back in those years RC equipment was still heavy. So I had requested from Z-Tron , a company making DIY IR kits for indoor airplanes, for a 4 CH IR unit that I could use with my small and lightweight heli developments.

At the time, the world was not as interested in small helicopters, as it is today. Z-Tron only had a 3 channel system and they provided me with a 4 Channel unit based on my request. I used this on the Robin IR and some other smaller and lighter helis I developed in later years which icluded larger 20", 4 ounce helis like the MIA Sport LE and even one of my very first House-FLY Sub-Micros and MIA PALM-SIZE(TM) helis that I have posted almost on every other micro heli or RC Micro forum in past years. Keyword search Mario I. Arguello, or MIA Designs or MIA Micro-FLIGHT or visit www.micro-flight.com for more.

The PiccoZ uses a similar IR system but only 2 channels with balanced mixing betwen the main and tail speed control for added simplicity, so it is not as controllable as my original 4 ch IR helis were/are, but it is good enough for a toy.

Designing, developing and making small helis fy with realism has been both a challenge and a long time passion of mine, the PIcco Z flies like a toy, out of the box, it is a toy, but I thought I could improve on such and I did.

Here are some pictures and a video of my original small helis, some have been sold and are still selling in kit form (i.e. MIA Bumble Bee Sub-Micro), and the PizzoZ with some of my own mods.

Hi Mario,
Welcome to the 'town! Nice - It is very interesting to see how a Piccoz flying fast forward that fast. Feel free to post more information about it. I am sure there will be people interested in reading and seeing more about it.

I like the little rods mod comming out of of the side fins. I have been thinking about doing the hammer head mod (another set of foam wings on the nose) to help with fwd flight, but those rods look kinda cool. What would I use to add some rods like 1mm CF ? .. I wonder if that would be to much over all WT for a stock Picco z.

I am using 1mm carbon rods for the skids. Weight is almost negligeable.

You can use almost anything that adds a bit of weight to the nose to force the heli into forward flight.

There are other tricks that one can do to make the heli flight characteristics different, like strategically adding fins, rotor trip devices, modifying the body, mechanics, electronics. I am basing this on my own experimental and prototypte work I've done in past years with my MIA Palm-Sise (TM) helis which the Piccoz is similar to in many respects. So the same mods work for the PiccoZ and other similar size and type of helis.
