Nice Len, very clean build!

Thank you Gunny, Its been a real pleasure building this plane. I almost forgot how much enjoyment you can get out of building with balsa wood.

Thanks Len...that will keep me going...I am done with both wings ...now doing the ailerons...I am finally figuring out to build one thing and then match the control surfaces to what they actually are...not what the laser etching might suggest...
Your pictures are so helpful....hopefully my beast will fly this season but like the old saying goes: " the last 10% can take another 90 % of time...dang..

Oh yeah-uhhhh! The yellow and red will look great!

Ahem....pictures?

Hi Guys.

Sorry for the lack of posting. It's been a whirlwind last month or so getting many things accomplished, both personal and model related.
I now have the Smelly Yak heading down the homestretch, I expect to paint the cowl red this weekend, which will be the last piece to the puzzle.
Its been a great build, a ton of fun and a reminder of how much more enjoyable it is to build your own plane than to just assemble one. This kit is well thought out and even though there are a couple small corrections you must make as you progress, there is nothing the average modeler can not handle.

Its a big plane... Lots of covering.



Tail wheel setup, the servo driving the wheel is inside the tail.





Snap Latch installed for quick and easy field setup. After chatting with Jim, we decided the best access will be through he inside of the cabin, next to the fuel tank.



Rudder horn was painted red to match.



Flaps are MOVING!!!!


Servo for the throttle. Easy to remove with 4 bolts, remember to keep the plane light. Peter says it needs tail weight, so no extra stuff in the nose


I added a fairing under the fin, so its permanently attached to the stab. I LOVE IT





Pinstripe, pinstrip and more pinstripe




Finished wing panel. ( almost) I have to add the wing walk tape and maybe LE de-icing boots

[ARUP]

De-icing boots for those 'to the moon' tows!

[Swiss1]

NO, for the Cumberland Spring event!

THIS IS A 6" WHEEL......





THIS IS AN 8" WHEEL



DA 150 ready to pull



Since the DA150 has a low tone, unlike the DA 100 and especially the 120, I'm going to try just can mufflers. We were paying attention to Peter's plane during the event last fall and it sure seemed pretty quiet. Of course my ears could have just been damaged from listening to Kevins Pawnee.

[Asher Carmichael]

Looking good, Len. Should be a “stump puller” as we say down south.....

[kjkavaney]

Awesome Len...glad you mentioned the wing fastener gig...I still can do that yet...once again, you have inspired me to keep going on this build...

[stevekremer]

I dont know? There was an awful lot of talk about making cans mandatory. We want quiet so we reduce the chances of annoying neighbors! Also it looks like you need 7" wheels.

I'll be flying the quiet Pawnee at Windy Ridge, we just instituted a noise limit... I don't think your Smelly Yak will pass!

[Steve P]

What? What? I can’t hear you over your tow plane.

[lenb]

I knew I would bait you two in!!! Mahwahahahah

ill put the 150 on mufflers against the 120 on canisters any day
Kevin, did you get the bill I sent you? It was from my hearing specialist.

[ARUP]

Put the letters 'G-O-T-C-H-A' on the side of your Smelly Yak! Like on the AT-6 race plane! lol

[LRFitch]

Len, Can you share what airfoil Peter used on the Czmelak?

Thanks,
Larry Fitch

[lenb]

Pete says it was his own airfoil that started life as a Clark Y\

Plane flies fantastic, it towed for about 10 hours at the recent Horizon Hobby Aerotow.

[lenb]

BTW

The wing fastener was a FAIL.
No mater how loose or tight we made it, the think kept coming loose and eventually I just put a bolt in the wing.

Like Peter says, the harder to put the wings on, the harder for them to fall off.

[kjkavaney]

Amen to that...I will send the cabinet things back to McMaster Carr if they accept returns !!!
Appreciate the pioneer work you and Pete put into this beast that I have yet to complete...slowly getting there...
Really enjoyed seeing both yours and Pete's in action this past week in Illinois...more incentive to complete mine.
