Just watching how the aeroplane handles at that cg looks spot on,would sound better with a twin in it.

Yes the CG is good or the plane would not handle as well as it obviously does.

Question is, W/the short nose of the J-3, would the FA180 be heavy enough to not need added nose ballast? I think not, hence the comment on the heavier twin needing less nose ballast to achieve proper CG.

I'm hoping my 84" WS 1/5 Wings Maker J-3 Cub flies like that W/a CDI fired FA91S on the nose. It makes 15# of thrust W/a scale diameter 15 X 5 prop. That's about 2X the all up weight so it should.

Here's the clueless "student" & the obviously unsettled instructor that will be piloting my Cub..

Yes that picture is not of my airplane.

The originals are buried in a file somewhere & I can't post as "attachments.

Here are my Photobucket images of "Pamela" & "Goose" in their proper seats.

I would go with the O.S. 160 for the best combination of size and power. I have one of these in a GP Sportster 90/120 and it runs great. I also have an O.S. 240 4 cylinder in a Sig cub on floats. The extra engine weight nicely balances the airframe/float combination and sure sounds great (will fly at very low throttle settings). With either the twin or the four, I would recommend a Keleo custom exhaust to keep the plane largely free from oil.

A flat four? Are you kidding me? What a sweet engine! I had to look it up. There are even YouTube vids of guys breaking them in. Sounds like music.

Thanks for the recomendation of the OS 160. I missed a couple of oportunities to get one while I was working to save the money. Now I am ready, so we are looking...

Should have looked a few months ago. They were going for just over $600.

Well..he did say it took him some time to save up for it and he's still better off than we are here at the moment as the aussie dollar has fallen behind the greenback for the first time in years.Luckily i had bought most of my engines when our dollar peaked against yours.

Hi!
Yeah!
The OS 1.60 twin with 5% nitro fuel and a 16x6 prop (not MA)is perfect for the 1/4 scale CUB!
