Scratch built maybe 25, 30 years ago. Decided to help Paul out with the finishing. The under coats were Sig nitrate on raw wood, Glassed nose & silkspan covering. Over the nitrate was brushed on Brodak butyrate clear. It was then sprayed with Sig silver. The Insignia white, black red and blue are Brodak, as is the candy blue with silver metal flake lettering. Top coat is Sig Lite Coat. Power is Lew Woolard Fox 36. Adjustable tank, leadouts and wing tip weight box. Shortened nose, larger tail.

Wow !!! That is unbelievably beautiful. Makes me even more frustrated with my lack of patience and skill !!

A beautiful job - I wish my finishes were even half as good as that one! Solid leadouts, though - I'm always afraid they'll transmit vibration down the lines and make them bind, a trouble I used to have before I switched to flexible cable. (But maybe I'm worrying too much - I recall that Juhani Kari once flew a kit Thunderbird to second place in the World Champs, solid leadouts and all!)

Absolutely stunning finish!

Kevin, I must warn you, that mirror finish is extremely dangerous! Your fingers could slip and the model could be crushed to matchsticks under your feet. Be very very careful my friend! LL~
Absolutely Beautiful. Sparky would be impressed.

Beautiful model!!!! What did The final weight come out?
-
Flawless...!
I don't have much experience with dope..especially not when it is brushed on but what you show here proves how good a brushed on dope [or lacquer] job can look.

Hi Paul, you would have to ask Paul what the all up weight came to. I do know the finish from the silver up was under 4 oz and the plane as it sits is balanced at the high point of the wing.

Chuck, it was just the initial coats that were brushed. The plane was a group project. I just did the spraying from the silver coats and up. Ive seen some nice examples of an all brushed finish though. Dennis Saydak's
Fierce Arrow is one of them. Myself... I am horrible at brushing. mw~

Kevin.. the quality of the work beneath the paint was a great head start. It looks deep and flawless.
I took a car that I had done all the prep work to [up to the primer sealer stage]...down to a body shop for an estimate. The Estimator did a quick look and feel of my prep and without batting an eye told me $15,000 to fix all the flaws and then shoot the color.
He said it was "Not bad for an amateur".....
I asked him to point out the flaws..so he had me pull into a paint booth that was set up with "Black Lights"..then he wiped one side of the car down with a solvent to give it a temporary gloss and the black light revealed every tiny little ripple and sanding error that I honestly could not feel.
The $15,000 estimate and the free "quality control demo" was a great motivator for me to put in the work to do a better job..!

My scratch built and modified Banshee, based on the SIG Kit plan, weighs in at about 45 ounces. The clear is still gassing off so that could drop a wee bit. The model was started back in 1986 when I was working out of Montreal's CYUL Dorval (I REFUSE to call it Trudeau na#) Airport, flying the night freight. I got the idea for the colors used on the Banshee, from the old Swearingen Merlin I was flying way back then. 5 moves later and I am back in Winnipeg(Home) where the project got going again with Saturday Building Bees in Dennis Saydak's shop, pre-covid. Mods included a 1 inch shorter nose moment, ribs all like the fully sheeted center section ribs with Cap Strips now on the open bays and the leading edge sheeted with 1/16TH balsa back to the now 3/16TH's square Spruce Spars. Pushrod exit inboard to avoid exhaust, Adjustable tip weight box and adjustable lead outs. Wider root for the flaps and slightly short of full span flaps. Adjustable tin hinged fixed 'flap' tip outboard. Enlarged and thicker 3/8TH's stab/elevator. Balsa nose fillet on the inboard side from the added nose ring to the wing's high point, all sanded and blended in and then glassed. Power is a nice old Fox .36 that I first had in a stock kit built SIG Twister. Had it re-worked by Lew Woolard some years ago. Friend and fellow C/L Club Member Kevin King does truly amazing finishes as I'm sure you'll all agree from his other postings.

Beautiful job Buddies!
Hopefully making it to Manitoba sometime this summer and I’ll get to inspect it in person.
Cheers

Hi Paul;
I agree that is is a really nice looking model! A lot of guys get a little too fussy about the weight thing, but yours isn't remotely what I would call heavy. I built a SIG Twister years ago, and kit bashed it into a profile version of the Shark.45 that I had, painted the same colors, trim and everything. I even did the leading edge sheeting and cap strip like you did, added the round wing tips that actually used the same ones as the Shark .45 did, and added the thick doubler on the nose. Tail moment was stretched out as per the Fancher modifications, added two inches to the span of the tail and reshaped it like the Shark, then silk span and dope for the finish. I used all the kit wood, and the ribs were so hard that I had to cut them with a band saw!! All of that and the weight came in between 45 and 50 ounces. I won a lot of contests in profile, Intermediate and Advanced with that model. I started out with a OS FP-.40, then transferred over to a Brodak .40 when those came out. Flew great with both engines. It's still hanging on the wall and I'll have to get it down this summer as part of my retirement plan, which is to fly everything that I have in house here that is ready to fly. It needs some covering touch up and some other TLC but I have lines and handle for it at the ready so shouldn't take too much to get it in the air. The wings on the Twister and the Banshee are pretty much the same, I think, just different tips, and they carry weight well. We had a friend here that had actually built a Twister entirely from pine, just to see how it would do. Finished weight on that one was 60 ounces or more I think, and would do the pattern!! FP-.40 for power cranking pout all it could, but I'm pretty sure he trophied in one of our contests with in Intermediate class!! I trade emails back and forth with Kevin so I'll be looking for a flight report on it from him. Keep us posted on here also , please.
Type at you later,
