I'm proud of my new Pentathlon! Just had 2 flights yesterday ahead of a cold front that is gonna make it unflyable here for a couple of days. Here are some photos of the bird.
This is a new power system for me. I've been electric for the last few years and decided to try "Gassifying" a pattern plane. This is the "proof of concept" bird and does it ever "prove the concept".
Power plant is an OS 160 modified with a walbro carb and using a ProSpark ignition system - Mueller header and aeroslave light pipe- standard length. With a APC 18.1X10 it is turning 7800 on the ground and has excellent power in the air. Running gasoline
il at 16:1 I set a 14 minute time and had about 1/4 of the 12 oz tank to defuel. It's early to comment on reliability with only two flights on it, but I had good power, linear response and steady runs through both flights. Idle is very low and reliable- so low that I'm gonna have to put an ignition cut off on it to kill it.
Total all up weight is 4950g.
Thanks to Dean Funk for the vinyl masks and graphics!
