Thought it was a .60 but just couldn't remember...C@$P day in the office yesterday so didn't even have a chance to do the research again. I have a few .60's, possibly even a McCoy so one of them will go in. It is an interesting shape Mike which will make for interesting sheeting. I don't like the way the fuselages are sheeted on the threads I've looked at on RCGroups, I'm planning on planking it in the same way as the Valkyries fuselage is planked, it just means the planks will have to be narrower to be able to conform with the "S" bend, it also means it will take longer to plank and it will more than likely have to be done wet.

It's been a long time since I posted guys but a LOT has happened on this bird. I'm not going to post each detail as it would take forever but she is at the point where her wings are complete, tail assembly complete as well as it's mounting, undercarriage on, wing seat laminated from .6 ply/carbon/2mm balsa/carbon/.6ply, now I just need to mount the wings and then get going with the fuselage planking. That done she will be ready to cover and then it's maiden on the 22 July.

Absolutely Amazing
Hi guys I am gobsmacked with the amount of detail that goes into building one of these Goldberg having just built my first ever full frame model Tomboy 36 FF, so I did some research and this is a 20 feet span Golderberg Valkerie on Flying Giants WOW if a normal version isnt enough work this is an 8 year project involving several builders!!
I ask myself who would have the balls to test fly this once completed?

Well guys there has been progress going on, LOTS of time consuming fuselage planking. Have five more planks to do and then add the front former, mount motor and do the infill to finish off the nose.

Great looking planking Brendon! When you cut your strips do you make the cut at 90 degrees or at 45 degrees to interlock the pieces? What kind of stripper do you use? I have the SLEC Thrifty Stripper I ordered from Hobby People thru my LHS as well as the Master Airscrew stripper. The SLEC channel is mounted to a 1 meter piece of 1/4" Masonite.
Off subject I just had to order replacement Swann Morton Super Tool blades (non-sterile Scalpel blades) for my SLEC Balsa Stripper. I find it more accurate then my Master Airscrew stripper when doing a lot of uniform strips all the same size. I ended up ordering a 50 pack of them from the UK because in the USA you can't buy them because they are considered a medical supply. Now I'll probably have a lifetime supply but I didn't want to risk a availability issue in the future with a 10 pack. Price wise the 50 pack was not much more than two 10 packs and I got free shipping. Ship time is nearly 3 weeks with two of that to be blamed on US Customs..

I use the Master Airscrew stripper and never had any accuracy issues. Should I build another one though I will be looking at getting someone to turn me a solid plug and try joining sheets, then soaking them for around 24 hours and then wrap them around the plug and let fully dry and then cut along datum lines and sheet the fuselage in quarters....that will of course depend on if I build another one and if I do it will be a bipe
There is just one issue around that though, the guys here already want to send the men with the white jackets to come collect me and take me to the funny farm
As for blades, I only use #11 surgical blades...cost me R100 for 100 blades and I get them from my chemist around the corner

I was able to get the #11 surgical blades and a handle to boot from Brodak but the stripper uses a Swann-Morton major surgical blade which evidently is made for Orthopedic surgeons. I think UK is one of the more lax in their controls than a lot of other countries. I know the supplier had a whole list of countries he can't ship to.

Sorry guys, I haven't updated this thread for so long as I was too busy getting her finished for our annual memorial. I won't go through all the build stuff as there is just too much, but she is finished and ready for 22 July annual. Unfortunately I was not able to get the O&R .60 started so did a mod and fitted an ASP .52 FS

Here are some pics of the maiden which took place on the 22nd July...also the hardware she brought home, best large plane, best scratch build (her little sister took this one last year) and pilots choice, she also took the maiden trophy.

Congratulations on completion, maiden and winning the trophy!
You are a glutton for punishment for sure, that has to be the most difficult and labor intense model plane I have ever seen. Years ago, in 1975, I saw one uncovered at a Hobby shop in Augusta Georgia and it was mind boggling even then. With the built up ribs, it's like building several dozen rubber powered ships. Did you get a count on how many pieces are in the wing?

Been almost a year since I posted here. She did it again this year, took the best large old timer trophy only this time it was on my late fathers birthday, he would have been 79 last Sunday.
As for the Cobra, she has come a long way.
Will do a small thread once she's done, but first off to hospital again on Monday
