The four stroke twin sounds great. The Master Airscrew prop is good for fields where it’s likely to be hitting grass, weeds or dirt but not the best for performance. An APC will wake it up although I wouldn’t have expected an increase in performance. The 30cc gas engine you went to is a much better match. My same sized Great Planes Giant Ugly Stick had a heavy, low power 40cc single cylinder engine on it when I bought it. I replaced it with an EME 35 and it has unlimited vertical now.
Ive got the Great Planes Big Giant Stik which is basically the same plane but with the traditional Ugly Stik Red Baron Fokker theme. I'm running an Inverted Saito FA180 with the Slimeline inverted pipes so our setups are so similar we even have to clean the same spots post flights....
NIce! I have a Great Planes Big Giant Stik with a Saito FA180 on it but have been debating moving it to electric using a Power 180 I happened into. Its really my only gasser left and 10s-12s sounds fun....
These deltas are my favorite planes to fly..i pretty much can set them up super fast or medium power using brushless motors...nitro is cool,but electric is perfect trouble free flying once you learn...Happy flying...
Thanks for the video. I’ve wondered how well the Saito 150 would power a 30cc Stick. I sand the leading and trailing edges of props for self protection. The 150S will bite very hard. The early ones are worse than later engines because they have a higher compression ratio. It’s the scariest engine I own. Too bad that your Ultracote is already failing. Every plane that I covered with UC ended up having to be stripped and re-covered with something else because of delamination.
The Saito 150 is a great engine (not scary when handled properly😉) and would power the 30cc Stick very well. Agreed: Ultracote doesn’t come close in quality to Monokote or other covering brands😏
You will need an RCEXL Twin Cylinder Universal Luminous Driver. It can provide ignition to the spark plug manually or via remote control. It will make the engine work sweetly.
As you probably know by now the nitro engines can be quite finicky to tune and to get running properly. The best way to learn is to find an experienced guy at a flying field to help you with the engine. There’s also videos on RU-vid you can watch if you want to DIY. Cheers🤙
I love how the weather didn't deter you from flying ! Been out a few times myself, just as soon as the Sun came up during the winter, and flew ! Kinda nice that no one else came out to brave the cold ! l ------@--🥶--@------
I don’t know which model of the Ultra Stick this is, probably the 120. If so, AND you want to make it perform and sound cool, just run a YS big block, from a 140 and up. You can find 140’s all over for not much cash. Personally, I’d put a damn DLE20 on it and enjoy the fuel savings. If it’s a current 10cc model, put a 75 or 90 size glow 2c. It will make it as crazy as it needs.
It’s the 120 size albeit it’s the OG version which is several pounds heavier than the 120 light version. I recently put a DLE 30 on it. It rips pretty good🚀
What engine mount did you use? I bought the green ultra stick and it didn't come with an engine mount. I'm going to run a saito 180. Should be plenty of power
The Saito 150 is relatively light in weight. I had to add a big chunk of lead ballast to the nose to get the CG into the accepted range. The 180 might be a better choice if you need more weight on the nose.
@@flyinghighjoe The 180 has a bigger bore in the same sized cylinder and actually weighs 2 grams less. Two grams is insignificant for an airplane that big but don’t assume larger displacement equates to more weight.
really enjoyed watching that….you just took me back 52 years. Well not the flying - I was never that good, just nice to see young guys having fun flying model aeroplanes and I like how you involve your brothers as well. Great keep it up. And yes that engine did sound good especially with the prop tips going supersonic!
I had the same plane but I had a Moki 1.80 2 stroke on mine. It eventually shook the tail off, in flight. OS twins are great engines, I love my FT-300 on my 30cc RV4.
It looks like you are on a farm, acres and acres of land to fly from. Why are you flying in the front yard? Get away from everything, cars, houses, son, and stand back a good bit yourself. No HOBBY is worth hurting anyone. Be SAFE above all.
I had the same airplane, but w a DLE 30cc. Your twin sounds great and makes the plane fly very well. A DLE will have more torque, and will need a bigger prop. I had to bend the legs inward to clear the prop from the ground, it pulled to the heavens.
I’m thinking of swapping the twin for a gas engine. Not sure if I wanna go for a Zenoah G 26 or G38. Thanks for the landing gear tip. I’ll have to do that.
That is a good aircraft . I had a smaller 60 size one . I was given a giant swizzle stick it had the wing broke . I rebuilt it and put big flaps on it . Many hours of fun with it .
