Ultra Stick 120
I have recently replaced my Ryobi 31cc on the front of my Ultra Stick 120 with a recently acquired Quadra 35. Weight is about the same, but couldn't ever get the Ryobi to run quite right.
Is anyone flying the US120 with a Q35? Right now, I'm about 14.5 lbs.

RE: Ultra Stick 120 prop
I have a us 120 with a 33cc homelite. I have an 18-8 prop that came with it. I only have
about one inch of ground for the prop. Could I lower the landing gear to gain prop clearnce?
Also there is a 12 oz gas tank, does this have to be up close to the firewall or could it be in
the very front of the wing section where it bolts on? Could anyone help me with this?
Thanks

I had a new taller landing gear made for this plane. As for the tank, you can place it in the back if you have the room and the carb will have no problem pull the fuel becuse the carb has its own pump. I have my tank in the center ( about nine inchs back from fire wall to front of tank) with no problems.
Weight is 14 pounds 5 oz.

RE: Ultra Stick 120
Hey Volture
It is a Jim Feldmann design which you can get at R/C Modeler Magazine, plan number 1307.
Stan's Fiber Tech sells the canopy, cowl and wheel pants.
It is a very easy bulid, just flip the fuselage up side down and bulid the front and rear turtle decks and recover.
This is a fun plane to fly! With some wind it can be airborne in as little as ten inchs with the Fox 2.4.

RE: Ultra Stick 120
Ground clearance with 18" props is always a problem with this model. Does anyone know of a source of CF (or Al for that matter) gear that will provide better clearance and is not too wide (at the fuselage end)?

RE: Ultra Stick 120
I've got an ultra stick 120 I salvaged from a wreck. I'ts pretty much stock, except for I'm using a Brison 108 cc Twin up front and a lot of plywood beef-ups here and there. I'm using a custom made landing gear from T & T. They will custm build you a gear to your dimensions. My "altered stick" weighs in at about 19 1/2 pounds and has about a pound of lead in the tail to balance out the Brison 108. I put some aluminum tubes in the wing leading edges and split the exhaust through them with a custom smoke muffler. Looks kinda neat with the twin trails of smoke out of each wing tip. I can't take credit for the idea, I copied it out of numerous magazine articles by flyers who have done the same thing. I'm currently flying a mejzlic 25 7/8 - 10 prop. (Custom diameter by groundstrike)

RE: Ultra Stick 120
Here's some pictures of my "altered stick" without the final smoke muffler hooked up. It just has some Bisson canisters in these photos, without the connection to the wing exhaust fitting. You can see the tubes coming out the wingtips, though. I started out with a 31 cc Ryobi conversion, but it proved too gutless for my style of flying. (Maybe the weedeater I salvaged it from had eaten too many weeds?) By the way, I'm brand new at RC Unicverse and I have no idea if the photos downloaded correctly and you can view them. If you casn't view them, let me know and I'll try again.

When you reply to a message or make a new post, if you will look down at the bottom left corner of the box there is a link - Upload Images.
Click on that and another window will open allowing you to select the images you want, whether they are on disk, hard drive, or where ever. As you select each one its' name will appear in the box. When you have up to four pics selected click on OK at the bottom of the box. Then post your message and they will be there. It helps if you have the images already on your hard drive, makes retrieval faster. Here are a couple of examples......

RE: Ultra Stick 120
There are two of the Ultra Stik's at my club. One is 60 size with an OS 91 4 stroke on it and the other is 120 size with a G-23 on it. Both fly great and land like a dream. Doesn't seem to matter what size or what engine, the plane just does right. The ugly fuselage shape is kinda redeemed somewhat by the novel covering job with the transparent wings. I like 'em both. Got my eye on a 120 size at the LDHS. (Long Distance Hobby Shop).

RE: Ultra Stick 120
Seem like a good bet....a couple hundred less than a similar sised Extra/Edge, and won't look to strange on skis or floats.

RE: Ultra Stick 120
I am thinking of purchasing an Ultra Stick Lite, and I read on the H9 website where you could use a 1.00 to 1.80 4 stroke. I have a YS91FZ available, do you think it would be enough engine for this plane? I want something big and docile, to counteract my Funtana and Saito 100 setup! Would it be a good idea to put the Saito on the Stick? Should I sell the YS and buy a 1.60 2 stroke? Thanks in advance.

RE: Ultra Stick 120
I have an Ultra Stick 120 Lite with an RCS 140-RE with tuned pipe on it. My favorite fun airplane used to be my Ultra Stick 60 with Saito 100, then the older US 120 with RCS 140-SE.
But the new lite version comes in at only 12.5 lbs full up ready to fly. It flat spins better and will actually perform a knife edge! With combined flaps and ailerons, it will turn about 3 rolls per second. With crosslinked elevator and flaps, it will do 15 foot diameter loops. With full Crow, it lands at walking speed, and will full flaps it takes off in about 5 feet, then straight up to any altitude you want.
Balance was perfect with no added weight after I mounted the elevator and rudder servo externally on the rear of the fuselage and mounted the tank at the CG under the wing. The RCS 140-RE with tuned pipe turned an APC 17x8 prop at 9500rpm right out of the box with a single cut on the pipe. Didn't go further since 9500 is the recommended max rpm according to Mike Dooley at RCS. And that's on 40:1 non-synthetic oil mix for break-in. Better performance than the Saito 180 (and I love Saito engines!), for the same engine cost. And instead of $22 for a gallon of 30% glow fuel, my gas/oil mix is about $2 a gallon, and the engine uses less than 1/2 the amount of fuel per flight (8 oz for a 12 minute flight).
The US 120 Lite is a winner in my book, expecially with the RCS-140.
