I like the 110. It has a very good power to weight ratio. weighs slightly more than the saito 100 and has power comparable to the saito 150. It also has the presurizing system so the tank maintains constant pressure of 8-10psi so you can put the tank right on the cg and not have to worry about fuel delivery resulting in much less noticible, if noticible at all cg shift from full to empty tank. I think that the 110 is probably one of the best powerplants for this plane because it is light, and powerful and doesnt vibrate a whole lot. My ys is a little finicky but it's pretty sweet. If your going four-stroke go ys110 and if 2-stroke then an os 1.20 would probably be a good match. It came out after i had my showtime so i didn't have that option but it is less expensive and i beleive less weight but don't quote me on that. 2-strokes are also a breeze to tune....but i love the sound of a 4-stroke.

it's a great plane but it is a pattern plane first and 3D second, it does not fly as slow as some other planes, but the thin wing makes it handle wind extremely well. 30-35k is no problem.

I fixed my landing gear issue by puting another piece of hardwood on the inside across the rails and then drilled my landing gear bolt holes through and used long bolts. It creates a sandwich.

The YS is the way to go on this plane.

I have looked all over but cannot find any posts as to how other flyers have dealt with the weak landing gear mount on the Showtime 90. Can anyone post links or pictures of how others have remedied this flaw.

Thanks;
Rod

I'm an experienced pilot and I still managed to take the gear out of the plane a few times. It really doesn't take much. I recommend you use some gorilla glue on the inside to help keep the landing gear blocks in place and then drill and re-tap the holes for 1/4-20 nylon bolts. If you hit hard or land off the runway, it will tear the gear out and leave the LG block in the fuse. If you are using the SFG's, they will obviously be damaged, but they would be either way. They are actually pretty easy to repair if you do break them. I repaired mine a few times and they worked just fine. The Monokote Pearl purple is a pretty close match if you can't find the Oracover to re-cover it.

The glue joints around the LG block were pretty weak in mine. Add to that the small wheels and a grass runway, (although ours is like a golf course!) and it has the potential to tear off pretty easily.

Thanks Steve. In fact I was debating between the 1.20AX and YS110. If I go with the YS it will be my first 4-stroke. I've been a 2-stroker up to now. How is the YS with vertical performance? Does it go like a rocket?

Duct tape...

Hey Al, I also don't recommend putting your canopy on pavement like that, it could get scratched...

it' not as insane as my last plane but that was a funtana s40 (before x50 was out) with a saito 82 or 91 in it. that thing was on the verge of being just plain retarded and ended up shaking the plane a lot that it would've broken from that....if i didn't crash it first

. but i got the 90 (excuse for a 15 year old you dump 1500$ into another plane) and i think the ys110 is a very good motor for it. It is not going to have the same power as people putting an os 200 in it or something but since it's lighter it's probably better for 3D. If 3D to you just means hovering and pulling out like a rocket then maybe not the right motor. it will pull out with authority but not a rocket. more power than that is not needed because all it will do is the same thing a little faster and probably shake the airframe a lot and weaken it. Go with the 110. Check out my video on youtube http://www.youtube.com/watch?v=smaw2tYHZ0k
that is mine with a ys-110. i don;t think it shows it pulling out but it hovers just above half throttle. And it would hover lower but i adjusted my carb setting so thet it is more linear. About 75% of your power comes when the carb is 50% open. I adjusted for this in the radio so that 50% stick is 50% power not 50% open carb.

Glad to see this thread still going. I went over mine this morning... after two years, almost 100 flights, and never had the cowl off, I figure she was due for some maintenance...

I re-plumbed the tank and replaced all fuel lines, tightened a couple of motor mount bolts, hit a few wrinkled places with the iron, and re-built my "custom" tail wheel; the little bearing I added was about to give it up.

And that's it. The airframe is still sound, covering still in great shape. This model is more durable than I initially gave it credit for. Hopefully, I'll get another 100+ flights out of it. A really nice-flying airplane...

Any of the old crew from two years ago still got yours? bubbagates; drumbum, etc....?

I'm in the process of building my showtime 90. I'm using a Saito 100 (had it from a previous plane, hopefully has enough power), and Hitech HS-5625MG's for all surfaces. I'm trying to figure out what size horns I'm going to need. The manual lists JR part numbers, but all I've found thus far are pictures of them on the web. No dimensions. Any recommendations?

Thanks,
Dave

We used the Dubro heavy duty and they worked fine. You can see whats left of a few on the picture. LOL

I think I will slap a ys110 in mine. I have a saito 120 and it is a dog.....especially @ 5000asl

Will the stock tank work?

If not what are the best options, is there a tank you can swap out with no mods? I know tetra makes a good tank..........is there a model that fits?

Thanks 871

You can use the stock tank with the Y.S., just do yourself a favor and wrap it in reinforced packing tape, (the kind with the strands).

Dubro's heavy duty control horns are GREAT for this plane. They are very strong and priced in such a manner that it won't break the bank to get 3D throws from your plane.
