nice pics. these are some of the ones i've saved, its amazing what some people can make! can you find all the planes in the one pic?

i think this would work with aa electronics, like 2 aa's on the same feq, ill try it when i sell sum of my stuff.

someone actually built something just like that. the guy has done some other larger ones that are very cool as well, his site is worth looking around in, even if it is in german. http://www.smartflyer.de/sm.html

20 grams, 4 AeroAce motors and props, 66mm in diameter, 4 channel infared RX, 3 gyros, 2 cell 145mah lipo. he did the programming of the RX and gyro controlls himself. very cool!

micro builder, the picture with the egg and the super small heli, who made it and what did they use to make it.

the maker of that tiny heli is the same guy who invented the Piccolo heli that helped start the micro heli craze, Alexander Van de Rostyne. he's also the guy who inveted the Gyrotor and PiccoZ, here's his site, he's got some cool stuff on it: http://pixelito.reference.be/ the heli in the picture is his own, not likely to be seen on the market for propbably quite a while, as he hand built it with carbon fiber and i believe used his own IR system for controll.

thanx, i'm going to go check his site out.

cool website[8D]. is the pixelito for sale?

micro_builder

My Feedback: (1)

nope, pixelito is a one-off. its an amazing heli, fully controllable, all by two motors and an actuator in the rotor to control the flybars. a lot of people have attempted to build a copy, only a handfull have been able to do it.

the closest we can get right now is his Gyrotor and PiccoZ.

if you like his site, Peter Muren (inventor of the BladeRunner helis) has some cool stuff on his site too, including his 2.5" rotor heli. http://www.proxflyer.com/index.htm

is the bladerunner ll or the bladerunner worth it??

micro_builder

My Feedback: (1)

well, i'm biased, as i love the BR line of helis, so i think they're totally worth it. they're marketed towards younger kids, but honestly, there's a lot of little things that need to be done to keep the heli flying properly, things that most younger kids wouldnt know how to do, so i think its more for people like us! they go forward very slowly, if at all, the motors can burn out pretty quickly (unless its the new KA-50 BR), the rotors can break and the lipo can fail, but i still love it, they're fun to tinker with. the mini BR being sold at Radio Shack is pretty darn good i think, better than the BR, worth the 50 bucks in my opinion. here's a thread on it: http://www.rcuniverse.com/forum/m_4219729/tm.htm

soooo, if you had to suggest one, which would you suggest the bladerunner or the bladerunner ll.

what are all of the little things you need to do to keep it flying properly?

monstermaker13

the blade runner 2 has more "upgrades" than the first. the only thing you need to do is let the motors cool for 10 minutes after each run or youll burn out the motors

micro_builder

My Feedback: (1)

my personal choice is the Mini BR. its only 2 channel, but without the tail motor its lighter, cheaper and doesnt draw extra current. plus, the tail motor on the BRs only work so well to begin with, so not having one doesnt make too much of a differance.
plus, its smaller, so it looks cooler

well, is there any normal maintnance that you have to do to the mini bladerunner?

Seek and Destroy

is there?????

micro_builder

My Feedback: (1)

basic maintenance to the BR helis would be proper lubrication. liquid graphite works wonders, its non conductive so it wont hurt electronics or motors either (probably better to keep it away from the lipos either way - just in case). i got a small can of it at the hardware store for a few bucks and it'll last me forever.

other things would be to do everything possible to keep the motors as cool as possible. removing the body is a good place to start, it'll help shed a few grams and lighten the load on the motors. you can use some sandpaper and scuff up the motor cans, and then color them black with a marker. assuming you're flying indoors, doing those two things can help a lot in removal of heat, which will keep the motors going for as long as possible. some have gone as far as to add their own home made heat sinks for the motors.

the mini BRs motors dont get nearly as hot as the normal BR, so the motors will last longer, but they can and will burn out eventually. you can get replacements though.

i think i'll get the mini bladerunner, thanks micro builder, again.

Just to set facts straight.


Alexander has had a lot of inspiration in other people's earlier creations that he rarely mentions and some readers don't know and believe are his. A lot of ideas implemented in Alex's are adaptations from others.

For instance:

The Piccolo started on the boards as a lightweight heli with the aid of brushless motors a la Pixel style. MIA actually came out with the formula for what is now sold as the basic FP heli, using and publicly suggesting the use of more affordable DC motors and a heli designed in a way that was more robust and user friendly with stock components. If you wonder where 99% of micro helis since 1999 that use standard 90 degree mounted servos and rather squarish frames with underslung battery between two carbon rods came from, compare them with MIA' early helis like the Mee-KRO, Sport LE and in particular the 1999 Robin 280 helis that used MIA's standarized 280 and N20 Motors. Now with the advances of lighter batteries, and heavier Micros, requirring more power than earlier ones, these 280/N20 DC power plants have become 300 and N30, still DC stock motors, sold with later micros.

The IR System for control of a Heli idea, Alex is using on the PiccoZ, is not his and it is absolutely nothing new.

Sergio Zigras of Z-Tron (USA) was the one person I know that created a 2-3 IR channel system for indoor airplanes way back in the early 90's. At a request by MIA, Sergio created a 4 channel specifically made for the MIA Robin IR heli, an early MIA 280 predecessor micro heli. Alex saw this and later on had contacted Sergio for a similar system.

http://www.gryffinaero.com/models/ff...irchopper.html

MIA in earlier years and in particular 2002, had also set out, publicly, the very first standards and formulas for a PALM SIZE Heli (MIA TM) with many posts in related threads for a heli of uncany size, weight, look, design and technically and mechanically similar to this years commercial Picco Z, via pictures and discussions threads posts like the ones below: Alex's never talked about his designs publicly to the point of showing people what would work until people started asking for information about the Pixelito which was after MIA Palm Size heli posts and thread had already mentioned and given away many options including a heli that used a 3 channel controller with mixed main and tail for simplicity using, at the time, an Dynamics Unlimited RFFS-100 3 ch receiver ESC unit very similar to the PC board on the PiccoZ except made to work via RF instead of IR.

Picture that follows is an early tiny MIA 3 channel heli with mixed tail and main motor speed, for simplicity, using an early RFFS-100 controller. But only used 2 channels, in reality, Up/Down and Righ/Left. This was also referened in MIA FREE PLAM SIZE HELI PLANS in one of the links below. Alex picked up on this idea quickly and made a video of a similar one calling it the Pixelito. The Picco Z works the same way except it has the additional help of an adaptation of the "Arlton Gyro" concept.

Following, a sample of an early MIA IR Transmitter built with Sergio Zigras parts, the current 2006 PiccoZ Tranmitter works very similar and it also has 3 LEDs on the front of the transmitter.

The autogyro rotor implemented in the Picco Z and Gyrotor helis is an adaptation of the "Arlton Gyro" used on the tail end of the early LMH 100 helis, to autostabilize the rotor.

See LMH-100 Early helis with Arlton Gyro.

Mario,

On another forum, you try to please me. On this forum you are bashing on me.
I never make claims on your stuf. I think you made and make great helis.
What is the bug that bites you if it concerns my stuff?
Your opinion on history, does not change history.
Even if it were true (and it isn't) that I just copied your stuff and got two worldwide successes with it (the Piccolo that I designed with Ikarus in 1999 and the PicooZ/gyrotor with SIlverlit in 2006), then still remains the question why you didn't do it?

hey guys, there's a new record for the lightest micro plane, new weight is an amazing 0.39 grams, wingspan of 3.12 inches!
