Hi Guys,
I've finished building my Ultra Stick 30cc size from Horizon and been flying it now. I came across one issue with the model and that is the landing gear is not long enough for 18" to 20" props. Our Pu'unene flying field usually gets trade winds usually by 9:00 am...and most the time it can get a bit gusty. So I am usually hard on landing gear, but hardly ever break a prop. I have broken four wood props on this model so far and that is getting expensive. Also the foam tires did not last more then a dozen landings...and started to show damage, so I replaced them with DuBro, 5" balloon, air filled tires. I am still dialing in my VVRC twin cylinder 40cc gas engine....but it is also brand new. So needs to fly more to really get all the power will have. I love the model...just making it a bit better. My model came out to weight at 16 lbs ready to fly.
Soft Landings Always,
Bobby of Maui

Maybe something like this, I have a 25% pilot edge and i put yak landing gear on it for prop clearance

Hi Guys,
I've been flying my Ultra Stick now for a dozen flights....and ran into a few issues with the model. I ended up going to United Auto and picked up a spring and installed it between the landing gear, about one third down the landing gear. I pulled the wheels off and I was surprised at the ware and tare on the foam tires finished in the kit. I installed a pair of DuBro air filled, 5" balloon tires. On the second flight after the modifications ( first generation, VVRC 40 cc twin cylinder gas engine) my engine seized up and broke one of the connecting rods. I had oil at a 40 to one mix Royal Purple 2 cycle oil on alcohol free 89 octane gas. I had a we bit of Lucas gas booster in the fuel. I had a good 2+ hours run time on the engine. I pulled the engine and sent it back to VVRC for repairs. I have had the engine for more then two years so I have no idea what it will cost to fix the engine. I have broken a few props because of the low prop clearance....five prop tips were broken or split. That is why I went to the larger wheels and spring. The winds here blow 15 kts. all the time and cross winds are common. So I know why my foam tires ware down like they did....landings are a challenge at times and I'm hard on landing gears.
Soft Landings Always,
Bob

I recently received a Great Planes Big Stik 60 built in the mid 90's that I am giving a thorough going over before committing to flight and would like to know what is a good starting point for the CG.

I have the Midwest Sweet Stik 40. I balanced mine on the center of the main spar. I can do snap rolls with mine. In my opinion, balance on the spar for most planes seems to be a good place to start.
Enjoy your stik.

You just beat me to it. Balance it on the spar and fine tune it from there if you need to.

Hello guys!

Count me in on the Stik Brotherhood. I up until recently have been without. Past Stik's were GP 40 Big Stik kit built, H9 Ultra Stick 120 Heavy, Scratch built Sweet N Low.
I have recently acquired a GP Big Stik 40 ARF from a club member to help train up a buddy and get him in the hobby. I also have on the bench a Kit Great Planes Big Stik 60. For power I have a Saito 100 laying around collecting dust but my spring for a 20cc gasser. For now I am thinking build light and the Saito will be a fine choice. Modifications will be the usual tail dragger conversion, build the wing flat, one servo for each aileron, and I am going to do some more Ultra Stick looking tail surfaces and I am getting rid of the scalloped control surfaces. I covered those before and it just isn't worth the fuss....plus I am increasing the size of the surfaces anyways. I think that is about it and will get some pictures posted once I get the build going in the next couple weeks.

i built a GP Big stik 60 and put an OS 90 on it. Not quite enough power. It had enough, coupled with extreme throw on all surfaces, that flew in any wind most would not. Im going to build another with a Saito 1.50 on it. That should be just about right??

My Great Planes Big Stik 60 that was built in '93' started out with a S.T .60, then an ASP .75, then S.T .90 and finally now has a Zenoah G20 which really makes it move with lots of authority. As the years rolled by I modded it quite a bit but it still flies great just like it did in its original state.

Ah! You are following Phil Kraft's example. He built the original as a test bed.

Gentlemen,
I wrecked my 30cc Ultra Stick. All my fault...finally got the VVRC 40cc Twin to run like a top...and I landed short, hit the top of a WWII aircraft bunker, flat...and did a number on my landing gear and fuse. The wing has slight damage, and will recover, but the fuse is another story all itself. I ordered a new fuse and tail feathers. I cleaned out the carb and intake area of the engine and all seems clean. Since the airframe hit flat...all I did is peal the gear off clean, and near perfect condition. So all I need to do is RNR some gear and switches, mount the engine, and cover one wing tip. She will fly this coming weekend. All the electronics seemed to have made it ok.

If I could figure out yow to post pictures I will post pictures. Any help here would be nice.

Soft Landings Always,
Bobby of Maui

When you are posting from the quick reply box at the bottom just click on the little picture on the left side of the happy face. A dialog box will pop up for a url to the picture or the option to upload. Otherwise instead of using the quick reply box click on the Go-Advanced button just below it. Then there will be a button that says manage attachments for uploading pics.

It seems to me that not until the late 80's or early 90's did plastic hold down screws become more popular.

youre correct. The Big Stick I built in 92 had the nylon screws holding down the wing

2nd place club fun fly
