I just picked up my Ultimate kit from the LHS today & will be starting on it tonight. This will be my second kit after my SSE & I will certainly have many questions for the RCU builders.
I will be posting my progress & promise to have lots of pictures. Digital film is so cheap!!

So far, I have purchased:
Kit
Saito 1.25
Futaba receiver with S3151 servo's for the aileron's & elevator
S3050 servo for the rudder

I can't wait to get this plane in the air!

Cool!
I have a few suggestions, if I can:
Make your own firewall of 1/4" 5 ply plywood.
Unbolt your carb and rotate it 180 degrees and bolt it back on so the needle valve is out the top.
After you get firewall in and the fuselage built, install the servo tray, servo actuators (what ever you chose-I used Sulivan), fuel tank, and horizontal stab...this is a lot easier to do than when you put the stringers on.

...just some ideas. Good luck, 'hope to see your build, Tim.

Hi Tony,

My lovely family gave me a GC Ultimate kit for Christmas (amazing how they worked out that's what I wanted). So far I have finisehed the tail feathers and the wings to the point of glassing the centres, one side of each is completed. I will finish them this weekend.

I have found the build very easy and quick to date although I did replace some of the balsa from my own stock and one of the ply wing braces was delaminated so I cut a replacement from lite ply.. I am going to replace the standard music wire U/C and have built hatches for the aileron servos in each wing although I used my own method rather than that suggested in the instructions.

I havent decided on servos yet and I plan on using the new Saito 125A for power. By the time they are released here in Australia the model should almost be finished.

Look forward to following your build. If you get stuck contact me and we can probably nut out any problems.

Cheers,

Colin

Thanks for the tips guys; I need all I can get!

So far, I'm certainly going to upgrade the LG & probably the Cowl & wheelpants. I'm up in the air on the elevator setup, but am leaning towards using the wishbone with a single servo. If I have any issues, I'll tinker with the dual servo elevator. I will certainly use the dual aileron servo's.
I'm also guessing that with the Saito 1.25 I don't need to put any weight in the tail so I'll keep the tail servo's up front.

campbec,
I was a little nervous on the difficulty of this kit because the SSE was pretty easy & this kit design is a little older. I'm glad to hear it's been pretty easy so far.
For servo's I was pretty set on going with digital's and I figured that the standard digital's would be enough for the dual Aileron's & a higher torque would be needed on the rudder. If I go with a single elevator servo, I may upgrade that one but if I go dual's I'll probably stick with two standard's.
That stinks that you have to wait on the engine, hope it gets there in time.

Tonight I'm making the servo tray out of 1/8 5 ply and I'll mount it so that it can be moved for CG if needed.

Here is the obligatory picture of the box before I start.
My first impression of the kit was good; All of the wood seems to be in good condition & nothing is warped too bad or broken.
I will say that the ABS cowl & wheel pants are even cheaper looking & feeling than I expected. I am absolutely buying the fiberglass cowl & wheel pants now. hehe. If anybody wants the ABS Cowl & pants that came with my kit just PM me. If you cover postage I'll be more than happy to send them to you. I'll just end up throwing them away.

I see that www.stansfibertech.com has the fiberglass cowl, wheel pants, & alluminum landing gear. Does anybody have those and are they good quality? Any other recomendations?
Does anybody make CF landing gear for the Ultimate? I have always liked the look of CF.

I also took a couple pictures of my workshop for those that are interested. I built that workshop over 2 years ago & am glad that I finally have a reason to use it.

I managed to spend about 4 hours in the shop tonight & completed the stab & one of the elevators.

The only issue I ran into was that the center platform piece that goes in the center of the stab was about 1/8" too long & was narrower than on the plans. I cut it to size & centered it on the plan's & I'm sure it will be fine.

Stan is the man...you are making excellent choices with his glass. All of my stans stuff has been superb over the years...wonderful glass work and almost no pin holes ever. Very good quality stuff.

As for the CF gear...I have to believe someone is making em...the GB Ultimate has been around for a long time. Sorry I dont know off hand who to point you at. One suggestion...if I may. I know this is your first .60 size plane...and I am guessing your first bipe. I would recommend that you give the aluminum gear a go first. CF gear has a tendency to want to delaminate at the bends on hardish landings. The Ultimate...in my experience...is NOT a floater. I am sure you can handle it...just saying...I would expect a rough landing or two before you get greasy with her. Once you get the landing down on this...THEN worry about tossing on the CF gear. just my .02 cents. =)

Thanks for the advice. I actually expect to bounce a few in and thought the CF gear would be the more durable choice. (shows how much I know) I'll stick with the aluminum. I'm assuming the Stan's aluminum gear is sufficient. (i think he gives a discount if you order it with the cowl & wheelpants)

I do have one other question on the Stans cowl. He has a regular one & one with muffler extensions. I'm not quite sure which one I should order. I have the Saito 1.25 & will side mount it with the exhaust coming out the bottom.

Thanks

I was only able to spend about 2 hours on it tonight. I finished the other elevator half & the fin.
I did notice that both elevator pieces have a more acute angle than the stab, so I'll have to sand about 1/8" from the front outside edge of the stab. I double checked that I built it exact to the plans, but the plans are just slightly off.

I did call Stan's Fibertech to ask them about the two cowl options. They said the muffler extensions cowl was to fit a pitts style muffler & has a chin on the bottom of the cowl. I have the stock exhaust so I went ahead and ordered the cowl, wheel pants, & LG.

I think that was an origianal Goldberg issue because mine, being the older kit, is off as well. Good progress though

I fly mine with an ASP 1.20 and it goes like a rocket, your Saito should go like shuttle launch with full boosters. I look forward to seeing your maiden flights. Great thread.
