I'm with you, Nigel. I like multi's myself but they have to have 3 or more engines for me.

I would dearly love to build a twin and am probably missing out by not building them, but I've seen the situation you described quite a few times. As far as I'm concerned about engines, the more you have, the safer it is!

I've had a bit of experience with 3 engined aircraft so I thought this info might help.........

I built and flew a Junkers Ju-52 about 6 years ago, built from enlarged Graupner plans. It was 1/14th scale, 90 in wingspan, weighed about 12 lbs and was well-powered by 3 O.S. 26 four strokes.

I'm now almost done with a bigger one, also from the same plans, about 1/9th scale, 120" span, on track for 30 lbs. There is a Ju-52 kit on the market that is about the same size and weighs 35 lb that uses 3 .70 four strokes.

Since 90's cost just a little more than 70's, and are the same size(Saito), I'm going to go with the 90's and have a bit of reserve power. I have been told that reserve power will help if you do have an engine out.

Right now I'm flying a Stafford B-24 with four OS 26's...weighs 14 lbs. and it flies great. I lost an inboard (#2) engine and didn't even know it until I did a low pass and saw it! Didn't even affect left turns...felt normal.

Good luck with your project! Ford Tri Motor? Ju-52? Savoia SM 82?
