   Tim (IHB) dropped around the other night for a Show n Tell and a Coffee. All I can say is they look even better in real life than they do in the photos. Well done Tim.

More progress on the Broussard. The covering is on, went better than expected. Next up is getting the clear coat and then the decals applied, as well as fabricating landing gear and wing struts.

Coming together very nicely Dan.  Did you find sufficient pictures to do the Portuguese scheme?

Thank you for the kind words folks, I humbly appreciate it! Smiley
Mike,
I mostly followed the scheme I found, however it is a complete guess on the wing as I couldn't find any pictures of the top of the wing. There was one shot in those you sent me, thank you, that showed the red cross roundel on the underside of the right wing. So, what the hell, I'm going to put one on the top of the left wing as well and call it a day.

Once I get the windows installed I can attach wing, tail feathers and wing struts along with ventral antenna and it'll be ready, "Gulp!!", for flight testing.

P.S. - This might be the last time I try to use decals. They do NOT like to stick.  Next time I'm going to try printing on the tissue again.

That looks great Dan!  A decal setting solution like Solvaset can help get the decals down tight.  That said, I've come to prefer printed tissue markings.

Good luck with the trimming - mine flew well on two loops of 3/32" rubber.

Got a video up on YouTube of a series of trim flights on the first day out with the Bellanca last month in Wawayanda, NY:

https://www.youtube.com/watch?v=PKHvQCsSoUo

Surprisingly easy to trim -- I was worried with the relatively high-pitch balsa prop and short tail moments but Mike knows how to design models that fly. Hope to fly it again soon, this plane is so much fun to get in the air.

Wow! Lovely to watch those Bellanca flights, Oliver. It looks great in the air.  I’m jealous of all that treeless space. Thank you for explaining your trimming process as you went too.

PB_guy, I'm calling the Broussard finished. But sadly, unless I can figure out a cure, it may never fly! Sad Sad Sad

Why, you ask? Well, I guess I done screwed up. After getting it fully assembled including wing struts and making the motor, I decided to give it it's second coat of clear to seal everything. Only thing I can figure is it was too heavy a coat, as the wing warped badly. It ended up with major washout on the left wing and zero to maybe a touch of washin on the right. I'll dig out the steamer and give that a go, but not real optimistic.

Another reason is I didn't pay enough attention to weight during the build and it ended up a rather portly 52g.  Shocked gives a wing loading of about .74g/sq in.

But I am happy with how it turned out. It was fun to work through the challenge of modifying the fuselage and making small detail like the radiator, scoop, venturi and steps.

Oliver - those Bellanca flights are just great to watch - each alteration you made makes sense and you can see the results. Nice work. Dan - congrats on the Broussard!

I can now add a flight video for the Bristol https://youtu.be/GTz4YE4AJ9Q.  it was a bit gusty. And we were a bit off trim for sure! I had some better flights - and some worse ones too - but this is the video I have thanks to son Hugo!

I do not have a video for the Yellow Cab. It flew really well straight off the board. Third flight on good winds it hooked a thermal and just kept going UP. Hopefully Mike was watching!

cheers

Broussard looks really good Dan. I like the color scheme and hope you're able to work out the warps.
THB, the Yellow Cab already went OOS??! That's what Embryos tend to do but still... Bristol looks promising. Glad it didn't nose-dive too hard in the gusts.

Sorry about the difficulty Dan. But congrats on the finish. Of course, you could remove the wing and recover and reassemble, or rebuild just the wing in entirety. But all that is in your ballpark, not mine. It is an attractive plane that I might like to attempt some day.

Don't give up on the Broussard Dan! 

If you've got a Monokote heat gun you can heat the wing panels while gently twisting them back, then hold them for a minute or so after removing the heat.  I've successfully removed (and added) warps and washout on several models using this technique. 

Was the 52g with or without rubber?  If without, it should fly ok on two loops of 1/8", or maybe a loop of 1/8" plus a loop of 3/16".  Won't be a floater, but you can still have some fun with it.  It came out looking really nice - it'd be a shame not to see it in the air.

Thanks Mike, will give t he heat gun a try. The 52g is with motor. It is one I had made for another model I think 4 liops of 1/8th. Is that too much?

Assuming your empty weight is about 40g two loops of 1/8" should be fine.  Give it a shot!

That’s great advice Mike. Dan if your heat gun will stand straight up on its own, turn it to med high and hold the wing over it while twisting. You fingers will tell you how close. Don’t try directing the heat gun by hand instead hold the wing over the airflow and for Pete’s sake keep it moving! Good luck!

Nice flights Oliver, thanks again for suggesting this cook up.


It ended up with major washout on the left wing and zero to maybe a touch of washin on the right. I'll dig out the steamer and give that a go, but not real optimistic.

Dan, definitely give it a go - you might find it flies in spite of the warps. In fact it sounds like all the warps you have will give left roll effect. Try flying it in tight-ish right circles with plenty of right rudder and the warps may just give you the correct 'hold off' aileron you would need anyway.

Holy Moly, Batman!!

About 20 seconds with the heat gun then holding the twist for another 20-30 seconds and the warp was GONE!! Hope to get it out for a trimming session this weekend! And the repaired MO-1 will be out as well.

Thank you Mike Kelly, Yak 52, Crabby, PB_guy for all the encouragement and advice. And to anyone I missed, Thank You as well.  I really enjoyed figuring out how to implement my version of Mike Kelly's design enhancements.

P.S. Mike, the weight without prop/motor is 37.4g The prop is 8"

Yes - I followed it for a while - but was still going up when I lost sight. It was a great flyer!

Ian - Please mark me down for a flight video (Bristol) though I hope to post a better one later on!

So sorry to hear about the OOS THB. I can honestly say that the last OOS I had was a Goldberg Ranger 30 almost 60 years ago. Flying with my Dad at Rogers Dry Lake in California. It had a Cox .020. I t was during a contest and the Air Force had one of their optical tracking rigs there for the contest. The Ranger was last seenin a thermal at approximately 2000 feet headed up and southwest!!

Dan - Woah! - 2000 feet! I'd be excited by that. I reckon I'm happier to have an airplane disappear into the sky than rot in the shed where it ends its days because I dropped a box of rubber on it :-)
I've done that too.
