LAUNCH! Schoolyard Stuff Nov. 9, 2010


I now have 60 MicroMaxx engines to fly.
This morning had perfect weather - blue skies, cool with just a slight breeze.

First up was the carded GOBLIN with a MMX engine.
With a BT-20 main frame, it doesn't get a great altitude.
But the Goblin is a old, reliable favorite.





The SKY SNOOP is one of the downscale Gooneys I haven't flown very often. It got surprising altitude with a MicroMaxx in it's tail.






Here's a new prototype - The UP! CUP.
It's like the Birdie's evil twin.

Sure, it's just a styrofoam coffee cup with an engine in it.
The engine mount and lug placement took a bit of work to get right.
It flew very well with lots of smoke!

First test was with a 1/2A3-2t. Straight up with featherweight recovery.
It made a strange "roaring" sound during boost.
It's second flight was on a A10-3t. Very stable, but I didn't notice the "roar" this time.

I read some "flying cup" reviews on EMRR. One builder made his out of a 20 oz. cup and noticed a lifting body style "glide" during recovery.
That's something to think about and work towards.
