Halmos	starting	building	his	quick-built	
kit	 four	 years	 ago	 and	 made	 its	 first	 flight	
	
	
in	 May	 2014.	 He	 started	 thinking	 seriously	 about	 its	 instrument	 panel	 during	 a	
weeklong	RV	builder's	course	in	Eugene	at	
Synergy	Air,	where	he	met	Gary	Worrell	of	
Aerotronics,	 who	 taught	 the	 avionics	 section	of	the	course.	
"I	 was	 nowhere	 near	 writing	 the	 panel	
check,	but	he	was	ready	to	sit	down	and	talk,	
to	go	over	my	thoughts	and	ideas,"	Halmos	
said.	"He	gave	me	his	cell	number	and	said	
to	call	when	I	had	questions	along	the	way."	
When	 Worrell	 retired	 from	 the	 shop	 in	
Billings,	 Montana,	 before	 Halmos'	 first	
	
flight,	 Jason	 Smith,	 who	 took	 over	 the	
	
shop's	 experimental	 division,	 continued	 as	
his	 always	 available	 sounding	 board	 and	
avionics	guide.	
There	was	never	any	question	of	building	 the	 panel	 himself.	 Building	 a	 reliable,
