4 stroke seams a little slow lately. I had a little fun Sunday. I took my Saito 30’s out of my Heinkel 219 and installed  two Saito 40’s. What a difference, first flight on 64 ft. lines about dragged me across the circle. Half ounce tail weight and 70 ft. lines now this is fun. I need to take the 2 1/2 oz. tanks off and install 3 or 3 1/2 oz. tanks, cuts off in the first overhead eight but keeps on flying with one engine.

Hi Willis,

This thing flying gotta be very impressive!

Love to see that flying on youtube

Martin

Martin I E-Mailed you a short flight. Hope you don’t mind
Willis

How bout me.

From memory, Time Machine 60 wing 660 square with a strait leading edge twin push rods both flaps and V elevators, Tom Morris controls. with the Saito 30’s 64 oz. a few more now. I blew up a side view of the heinkel to the size I wanted then stretched it to the length that I wanted. I got carried away with the rudders They are way to big but this is SEMI scale. The fuselage is covered with 1/64 plywood and does not twist at all.

Willis, received the video.
Willis, do you play the blues-because brother, your groove is outstanding!! Either you, your plane, or your engine combo is laying down a seriously good track. Your plane is definitely in the pocket-a winner.

Funny the only time the rudder didn’t break off is when it flipped over on the grass and broke the stab.

 Great stuff Willis!

 Could I ask you to measure up and give us an accurate spec on the wing and stab spans and areas? I'd really like to compare your Heinkel to my PBY. I've been debating making the exact engine swap you've done here, Saito .30's to .40's.

 Thanks!

 Thanks Willis. I've currently got 1.8oz machined stainless spinner nuts plus another 1oz of lead in the nose compartment on the PBY. I can afford the extra weight of the .40's and then likely take away some of the dead weight. You've got me thinkin'! 

Neat plane.  I particularly like the last pic of her, she looks like she's rounding out on final.  Very nice.

 Willis,

 I've got 3-1/2 ounce wedge tanks on it, that's the biggest "off the shelf" ones that will fit. If I end up needing bigger ones I'd have to make them, yuk.

 I'm going to have to start all over with the prop selection process, but I'm hoping that the Master Airscrew three blade 10x7's or 10x5's I have will work out. I've got some black Tornado three blade 10x6's I can try too. I know you can't tell how many blades there are when they're spinning, but it just doesn't look right with anything but three bladers on it.

 It will be a while yet but I'll post a report at some point this spring.

 'Til then, 

 Thanks for the advice once again Bob, sounds like a reasonable plan. But what Wayne might do though is try the same basic process, but starting with the new black Evo props since I can get them readily at the LHS. Maybe like a 10x6 or 7. Another thing is that I've only got room for a 10" prop, maybe 10.5" at the absolute max. I'm really curious about the Evo props because I had great improvement with them right at the end of last season but I ran out of weather. Right away though I got a feeling they might be a great prop for a lot of applications, I'm also anxious to try them on some .35-.40 single engine stuff too. They also ran real smooth and quiet. Anyway, I'm just hoping that in the end one of the three bladers will work out for the PBY, we'll see.

 BTW Bob, I think you mentioned it before, but where is the best place to get the TT props from. I'd never even heard of them until you mentioned them.

I found the Evo props to be not that great but might be OK if they were repitched. The TT props can be ordered direct from TT  see the "Props for Saito 40" thread below..

When I tried an Evo 11-7 on one of my 40's I had to run the RPM up past the point I was comfortable with to get the lap times back up. This told me it wasn't really a 7 pitch, would guess something less than a 6. At the time I was looking for a stock prop I could recommend to replace the Rev-Up 11-7. The TT needed a little RPM increase over the Rev-Up (100 RPM) but was better than the Rev-Up overhead so now all my 40's are running TT 11.3 X 6.5's. Bolt it on and go fly, not bad for a $2.00 prop if you buy them 6 at a time. This prop should be your standard from which to judge anything else you try. If you have to put 3 inch wheels on for a few flights, so what at least you will have a good reference in which to work from.

Bob,

 Three inch wheels won't do me any good, it's the prop to fuse clearance that's the issue. When I designed it I wanted to keep the engines as close together as possible and didn't think I'd ever need bigger than 10" props, because I was going to be running .30's.

Ya that would make it a bit difficult, hope you come up with something that works. Keep us informed..

Go to three blades.
