It has the shapes. More wing and tail than would be scale, I think.

Do you have a particular purpose in mind for it?

I used to prefer the red painted version with the elaborate wave in the tail, but the earlier silver and blue paint jobs have been growing on me.
I built a Blue Pants as a kid. Wish I still had it. Might even learn to fly it.

Hi PerttiMe. Its mainly for stunting and loosely based on Dick Sarpolous's Akro. I wanted a design that I knew was a great flier, and ya, I was tempted to make the wing closer to scale, but decided not to take the chance.  From the pilots view it's mostly the fuse shape that you see anyway. Both Tsunami's silver paint scheme and the red are nice, but this one's going to be the red version.

Of coarse Tsunami had to have a spinner. In this case it had to be a 1 and a half inch one. Can't remember seeing a 1/2a model with a spinner this big. So to fit the Tee Dee I had Paul Gibeault make a bushing for this one. At 20,000 rpm even a hole slightly off center could be a problem.

Hi Wayne, I think I've found almost all there is on the web for Tsunami. Skip Holm had a great story. He was flying Tsunami and the engine quit. So he radioed JR and calmly told him about it and asked
 him where he would like him to land it. 😁 If I'm not  mistaken he was going to land it on the freeway. But then the engine started and he told him Never mind.

If you check on Ebay you can find Cox spinners available in the1-1/2" diameter in a few different colors. I've been searching for one in1-1/4" and it's been a little harder and the ones I did find are only available in black, White, and yellow and wouldn't you know it, I'd like it to be red.

Lil Tsunami's catastrophic engine failure: I buy all my 1/2a engines from Paul Gibeault. This engine was going to go in the Lil Tsunami, but that was not to be. In Paul's words here's what happened: "Well as you recall I had one surplus TD that I was willing to let go of and I made a deal with you to buy it. Almost ANY used engine from me MUST undergo an Inspection & Test Run to my personal standards before I am willing to sell it.  That allows me a 99%+ customer satisfaction rating.  So that initial engine looked perfect up until the test run. During the test run, it was noted to putting out superior power than normal. As I was  admiring such excellent RPM's,(something between 22 - 23,000)  the engine suddenly stopped!  Upon further inspection I noted the con rod had snapped in half & punched it's way right through the crankcase! This of course essentially trashed the engine which is why you ended up with the last personal TD which I owned (which is also a thoroughbred) powerful engine. I know where cheap replacement parts are if I ever want to re-build it, but have no plans to do so at the moment.
And now you know the rest of the story..."

Cheers,

Paul

p.s. I've blown up A LOT of .049's in my time, but have NEVER seen a con rod snap in the middle like this one did!"

Adjustable tank and engine detail. I'm not sure if I like the feed tube coming out the top. I will fill through the top and cap off the top. Hopefully it works.

Would have liked to use an aluminum Fox 1/2bellcrank, but the hole for the pushrod is to far away from the pivot point, and there was alot of slop in the bushing. Not really ideal for stunt. Settled for  the Cheap looking plastic one.

 I have used Sig 3" b/crank on a lot of my half A models and they work fine, I use the p/rod hole next to the bell crank pivot post so I don't have a lot of throw.  See what you can do with this, you can also use the same crank with the 2 1/2"  line spacing, hope that this helps..

Time for paint!   S?P After the 3 coats of clear were brushed on and sanded I skipped the filler coats and went straight to the color coats. Joe Adamusko suggested the base coat color to be a light grey. So I sprayed on a coat of Polar Grey but found it to be to dark. So I sanded it off, added white to the paint and resprayed it.
