Pretty sure you will tell us all about the YS bit, but then all you really have to do is don't let that left hand fall asleep. Yes it sure is wonderful how thanks the internet we can communicate worldwide on what I consider as one of if not the greatest hobbys around as I've just now I've been on a posting with Telemaster in France.

First post here. I have a survivor CG Extra 300 kit I purchased back in 1995. It sat idle until 2004 when I framed it up, then it sat again until last month when I became interested in RC flying again and started taking all my RC aircraft out of mothball. Mine is coming together slowly but steadily. I have been working on it after I arrive home from work for roughly about 1-2 hours before dedicating the rest of my time in the evening for the wife and family. This one will be powered by a YS120 NC, NIB/NOS. Thanks for all the great tips and info here.

Flew mine yesterday. It is an awesome plane. Please beware though this is not a trainer. If you know how to fly that's great, consider getting and flying a trainer type of plane before this Extra.

Thanks for the advice but I am well past the beginner stage. Before I bought this kit, I built and flew on a weekly basis a CG Sukhoi. That one is powered by a YS 120AC with a smoke system. I still have it and recently replaced all the dead servos, did some maintenance on the engine and test ran it. Had many other planes from slope gliders, aerobatic EZ arfs back in the late 80s and early 90s, to electric and nitro helis. I've shelved and revisited this hobby thru the years.

Hi your going to love the Extra, yep its an old design but one of the best in my book.
i like you power mine with a YS 120 SC.
The landing gear is the planes only short coming, dump the wire gearand get some Aluminum or Carbon fiber and make the mods needed to use it and go fly.
i call mine the little plane that thinks its a 40% .
it is a very honest plane eith no supprises if built correct.
i hope you enjoy yours as much as i have mine over the years, i dont much fly it anymore with the gas and larger planes in my hanger, but theres no way i would be W/O one. I have several sets of plans plus the ribs plans as well to make sure i could rebiild or scratch a new one if needed.
Fiberglass Specialitys has the Cowls, Canopys And i think the alum landing gear as well, if not its not to hard to come by.
happy flying.

I'm arguing with an I pad, it forms it's own sentences. Fantastic choice in the kit/plane and engine. Mine had the YS NC but I replaced it with an FYI model when it got old. The F was NIB too.
I've moved and no longer have a field/club close enough to fly at.

As said before you are going to love the Extra but even more so how it flies.....like a dream. It's just about the nicest flying model I have ever flown bar none and it has absolutely no bad habits. Mine is powered with a Zenoah G23 lightened and converted to CDI by Ralph Cunningham.

I built several Goldberg Extras when they were first introduced and thought they were about the nicest flying airplanes that one could hope for. That is until I built and flew the Goldberg Sukhoi!

Did anyone realise that this month was this thread's 13th birthday.......it's been quite a ride and an enjoyable read and still going strong. It's also been the catalyst for my making a few new friends here too like Gene (Gray Beard), Steve (Ole Scale Guy) and Richard (Cyberwolf) to name a few.

Lets face it Goldberg made Some very good planes, the Extra, the Ultimate bipe, the Chipmunk, the Sukhoi are some of the kits i cut my teeth on back when. I still have an Extra and a Sukhoi, while the extra has more flights than i dare to count the Suk is almost new just sitting in mothballs so to speak waiting for me to fly it.
it has a gas converted OS 160 for power so it will be fun LOL. I had two of them but a radio glitch cost me the other one of 19 years i wasnt happy to say the least
Karol has brought up some very good points, you talk to folks on here and get to know them just like they were family and build some very strong ties and bonds.
Happy Flying All.

Cyberwolf, I agree Goldberg made some nice building and flying airplanes otherwise they would not have been around as long as they were. I only have experience with two of their kits, the Sukhoi, and this Extra 300. I'm currently searching for a deal on another CG Sukhoi kit. I lost the first set of plans with the fuselage and rudder drawings. But that's a whole other thread to start.

Last night I installed the aileron servos. Today I am staying home "sick". Sick enough to stay out of the office but will see if ok to continue mounting the servos for the elevators.

+1 and to you karolh

Still figuring out the best way to post images. I just finished installing all servos. Wrapped up that job last night with installing the throttle servo and cable to the YS120. Installed dual elevator servos internally at the tail end of second compartment behind the cockpit. I don't like the way other dual elevator servos setups look with the servos sticking out. I had to reverse one of the servos by swapping and resoldering wires from the feedback pot, and the motor. It's really looking good. I have all the colors of MonoKote I want to finish it in, red, white, black, and silver. Photo I am trying to attach is from a couple weeks back. I'll try posting some recent ones later.

I thought the days of reversing servos by swapping the wire positions internally was a thing of the past, but at least reading about it brought many fond memories of my early R/C days when that was the only way, unless of course you bought a reversed servo. Back then some radio sets came with a reversed servo included.

plankpilot

I opted for swapping wire positions in the servo because the LHS didn't have any reverse servos, and I did not feel like ordering one and waiting for it. I could have used another channel and used my radio channel mixing functions like I did with my E Flite P38, but I went old school. It only took a few minutes to re solder.
The next puzzle to solve is muffler and cowl fitting. My CG Sukhoi is fitted with a YS120 and Slimline Pitts muffler w/smoke. It fitted nicely with that nice fat round cowl and gave plenty of room to work in, but this combo with the Extra looks a little more challenging. I already have to remove the valve cover to install or remove the cowl. I never really favored cutting up huge holes in cowlings. I know Fiberglass Specialties makes an extended cowl for Pitts muffler. Has anyone else used a YS120 or 140 with the Slimline Pitts muffler? I am curious to see how it fits with either the stock cowl or an aftermarket fiberglass cowl. Attached photos show how I have the cut outs for now. I cannot even screw on the YS exhaust pipe and muffler at this point without having to do more cutting.

Hi there
i use the YS 120 and the header pipe they originally come with back when. My cowl fits nice and snug around the head just like yours, but i have no need to remove anything to get the cowl off.
its been a while but it seems like i do need to loosen the header so it will turn to clear, but other than that its a straight gorward deal.
On another note i pulled the extra out last weekend checked and rechecked eveything changed the battery and fired it up. That old YS-SC barked to life in 3 flips and ran flawless.
So with a reciever update to 2.4 i did a ground check topped it off and flew it.
i let my son fly it after i had the rodeo under control, supprised me it was that far out of trim.
he couldnt believe that i have had that plane all this time and was not flying it.
He became another GB Extra lover at once.
we flew it off and on for two days over the weekend flyin with out issue.
There a great plane and with the YS in the nose the performance is unbelievable.
Your planes looking great keep up the good work soon you will be posting what a sweetheart it is.

Happy that we were able to help another modeler get introduced to one of the all time best flying models. Treat her well and for sure she will give you many enjoyable flights. Do you have any pictures of your creation to share with us ??
