Brushless Twin Pico (highly hacked)
Brushless Twin Pico Stick
Well...I'm just about ready to "maiden" my newest experiment.
I have been having a ball "hacking" numerous Pico sticks, and have several dual aileron, brushless wonder motors, and even a wing!...etc...anyway....this is my first attempt at a twin conversion.
One of my best flying conversions is a dual aileron Pico, single motor with flying weight coming in at 9.1 oz....and all of these "hacked" jobs fly really really well!
This twin comes in at 14.3 oz....so I wanted to take some photos to "memorialize" the build in the event it does not survive the "re-entry".
Coming in at 150% more weight, but 200% more thrust than a Pico rocket I've already got in the fleet is going to probably be a handful.
Its been a kick..LOTS of small custom components....can't wait until the 3D printers are more affordable!!
I'll post "after maiden" results in a week or so...waiting for counter rotating props.

I received my counter rotating 8x4.3 GWS props, and bench tested the power system. The flying weight is 14.5oz
Using a 3 1300 mah cell lipo....I was pulling about 11-12 amps combined
Or about 122 watts/lb
I'm thinkin it ought to have adequate power....

The Brushless Twin Pico flew right out of my hands....and I started with just a few clicks of "DOWN" elevator (nose up) to help in the hand launching.....it flew fantastic actually...no trim necessary.
The speed was slower than I thought it would be....but it flies with "authority".......maybe not unlimited climb...but I didn't push it too much to start....
The one big thing that totally surprised me, was that as while I was putting it through the "stress test", I could NOT make it stall....at throttle off....the glide was straight and true...glides very well...but not a glider.....it loses altitude pretty quickly with the props wind milling, but the forward motion is very slow....making landings really pretty easy....it will take me a few times to master a "flared" landing, but man ...I'm a happy camper.....there were a number of points of concern I had....but everything worked great.....
If my "cameraman" is able to load video...I'll post a link a bit later.....ohhh...and aerobatics...yeah...very very snappy...pretty much anything I wanted...it did....
