Guys I have a .25 size sunrise that I have had built for awhile now but the cg is totally off from what the book says (the book says 2 1/4" +- 1/4 from the leading edge at the center section of the wing). I don't want to pile it up on the first flight because of improper setup. The model is setup with all standard 3004 futaba servoes a custom battery pack that I made to fit this little thing and an older K&B .20 that I had . My problem is that it is way tail heavy I added every lead weight I had for setting cg (about 7.5ozs.) around the firewall and it still didn't come out right. Where should the cg be and where should i set it from? That much extra weight seems excessive to me on such a little plane. The sunrise is only my third plane that ive built so i'm not very knowledgable yet. If anyone has experience with these planes and can help I would greatly appreciate it thanxs.

Do a search on cg tequilla sunrise arf . You should find information concerning the CG. I have a OS .25FX on mine. The CG is as the manual tells you. But I had to add 1 oz to move it forward. This plane handles very different from anything else. I was able to balance with no weights to begin with. I moved my engine forward and used the regular battery pack just over the fuel tank.

You’re probably not going to get much response on this. The Tequila's were an early ARF that got a bad rap and deserved or not, many people despise them. I've had two .25 Tequila's, probably the only person around that can say that, one is enough for most. I had a very light Norvel .25 on my first and a OS .32sx with a very light Mac's pipe on my second. Neither of which did I have to add nose weight! I was also using a very small NiCad pack under the tank. I don't have any instructions left but I'm sure I used what was called for on the plans. You should be measuring and balancing it at the wing root, not the tips. Right? I don't know what else to say other than I had NO issue with mine being tail heavy.

This plane is a handful to fly, I think that's why I liked it. Go easy on the throws, especially the elevator. Too much up and it will snap roll even at high speeds. It glides like a lawn dart and you have to keep the speed up on landing. Wheel landings are obviously preferred. Ground handling is okay but I wouldn't recommend it as a first taildragger. Hope this helps.

After reviewing my old RCU Tequila posts I'm kinda' gettin' the urge to find another one. Click below...

when i built mine i dug some of the foam out of the floor of the fuel tank compartment and put my flat battery under the tank. also i had a norvel .25 b.b. on mine and the cg came out good. beware! the sunrise is a handful to fly even for experienced flyers . that small wing has high wingloading it does not float down for a landing and it's high speed and small size means you will have to stay right on top of it!........good luck!

i told the poor guy about the same thing you did about tg sunrise's flying qualities. hope we did not scare him in to not flying it. something of interest. two years ago i was in a hobby shop in orlando florida. this place had so many kits and arfs you could hardly walk around in the store. i was surprised to find of all things in their store...........a tg sunrise .40 arf. i did not know they made one?. i opened the box and checked it out and it had a quite different scheme on it as of the .25 version. the store owners son told me it was a old arf and were not manufactured anymore. he told me it did not fly like the smaller version(speed wise) and it lost it's popularity. i just thought this was interesting.

Yep, Global did make a .40 size but not anymore. I can’t believe they still make the .25 but all the big mail order shops are still selling it, in stock. For $89.00 you can have another one! Global also sold a biplane version of the .40 size Tequila in a KIT. It was called the Global Tecate (Yes, the BEER) I guess Global’s marketing dept was targeting the US Alcoholic RC Aviator demographic.[sm=bananahead.gif]
Anyway the Tecate had even a worse reputation than the Tequila’s. Take every bad thing said about a Tequila x2 = Tecate. These cool looking, quick, quirky little planes from Global’s Old-School Dept. still have a small cult following. Of which I guess I’m a member.

guys thanks for replying, I did alot of searching before buying this plane and know the reputation of the plane. dont know if i can actually handle it or not but thought the k&b needed a home. The plane is built according to the book and I am checking cg from the center of the wing and 2 1/4" back from there. The batt pack is four nicad aa cells mounted individually along the fuse(two on each side) as close to the front bulkhead as i could get. This got the batt weight as far forward as possible without going into where the fuel tank is. Was thinking about a bigger tank in the future and saving room up there. I built a thunder tiger trainer 2ooo and a UCD 60 both of which came out needing virtually no weight. This is why I can't see this one needing so much weight that it dosen't fit on the firewall. Also another thought when I got my plane the manual that came with it was for a 40 size did any of you use these specs instead? I got a 25 size manual from global before I put it together.

Your manual is correct 2 and 1/4 inches + or - 1/4 inch. I found this old review in MAN.

Try and get a flat pack battery up along the left side of the tank. A Hayes 4oz slimline tank may help. You probably won't get much bigger than that in there. And you may not want more then 4oz. You'll be pretty rung-out before that 4oz goes dry. I used a too small 270mah nicad with the stock tank, I think. But I had to check the charge before every flight. Now with NIMH batteries you should be able to find around a 500mah to fit.

hey edh13 did you ever weigh one of yours what did it come out to if you did? is it possible that the little k&b is to light for the front of this plane. would it be underpowered anyway, i know that bushinged k&bs were not known for being powerhouses. there is an os .40 on the bench to. I already test fit it and wont take any mods to put it in. i've got a 4oz flex tank on order thats all the bigger I thought i'd get in there too. you said go easy on the control throws how easy? according to the book or less than that. I set them up to as far as they would move didn't plan on flying it like that though. i know that these planes weret built for speed not 3dish aerobatics.

No I never did weigh one, they are heavy. If you are forced to add nose weight with the .20 I would definitely install the .40 instead of the .20. Especially if the OS.40 is a .40LA. It is small and relatively light for a .40 and it will put out a little more power and more torque than a BB.25 size engine. And it's about half the price! Not too much to worry about when, sorry, if it crashes. I had a .32sx w/ a pipe on my last one and both were ruined in the crash, that hurt. If the OS .40 you have is a .40FX/AX I think it would be too much for the plane / pilot combination.
I don't remember what they give you for throws in the instructions but you may want to use those for the high-rate and about 60 percent of that for the low-rate
