  • Can you elaborate on why you prefer it now that you've converted to electric?

  • certainly....no glow fuel mess, im converting everything i fly to electric right now. the main reason is that twice with this plane i was in a low hover and the engine quit on me for no apparent reason and required substantial rebuilding of the bottom of the airplane. i know that things still fail with electrics but i feel more comfortable with electrics myself. it really is a personal preference. the 1.60 had tons of power in this plane and i am about equal with the electric

  • Nice flying, nice plane. Good song, too, though I'd rather hear the plane engine. And the OS 1.60 looks like it gives plenty of power - cool! I have one, no plane for it yet. Good to see it can haul a 74" like this. Have you heard of a 1.60 used in larger planes?  I was going to put an OS BSG-1 3500 into my new 78" Texas Hurricane, but decided to go 50cc gas instead.

  • i know it will fly a bigger plane easily it depends on what performance you want to get. i converted this plane to electric now and love it way more!! thanks for the comments

  • Thanks for the response. What size electric motor is the equivalent of an OS 1.60 2S? I have two small electrics myself (a Supercub (with brushless, lipo, ailerons), and a Super Sportster (48"). I'm amazed at how fast the Super Sportster is - electric motors really DO generate a lot of power. Just not crazy about short battery life (so I bring seven batteries with me!). Am now building a third electric - a 57" Extra 300S - designed for gas, but I'm converting it to electric.

  • apc 18*6w

  • hello again, what size prop you got on urs? i had an 18x6 W now master classics 18x6 which is crap, im gonna go for ther apc 19x8W, ur prop looks bigger than an 18 x 6, which one u got?

  • cheers for the info

  • i have the perry vp-30 pump with the bisson pitts muffler. i am a newbie when it comes to pumps so i cant help much there. it takes some trial and error and you have to lean both the low and high end to the point where i thought was too much but it was just right! good luck

  • i have the 74 yak in the red scheme, with the os 160 aswell, but i cannot get it to run right at all, wot set up have you got? pump? tuned pipe?
