On 25/Sept/2006, my "collection" grew with the Micro Mosquito. I bought it from Radio Shack for $69.99. The very first flight was worth all that money.
This little helicopter from RadioShack delivers pretty much everything it promises. The packaging was sturdy and the instruction manual is well written and easy to understand. There are 2 different frequency ranges available for the controls; 27 and 49 MHz. It's about 16.5 cm and weighs a mere 20 grams.
After unpacking, you'll find that the first flight is only minutes away... You just need to charge the battery... There is also a spare prop for the tail rotor as well as a beefier one for slightly faster movements. I use rechargeable batteries on the go...
... and a 7.5V transformer at home for the charge station. Flight time is indeed at the indicated range, 5~7 minutes for about 25 minutes of charge. It's a lot of fun for sure.
In September/2008 I had to replace the battery in the Mosquito. The old one didn't
take the charge any more and eventually wasn't even able to lift the helicopter.
I bought a FireFly at CircuitCity on a Clearance ($7.99) with a half-broken blade and
did the heart transplant in 20 minutes. Now my old Mosquito is back buzzing again!
