I'll try to have some better, more realistic numbers later.
I'll try to have some better, more realistic numbers later.
I generally build a model and install the tank however it fits conveniently, has anyone actually experimented with changing the tank height in the same model, with the same engine? Another point though, in the case of an ARF, especially this one, the tank height is pretty much fixed, and there really is no choice but to invert the engine, therefore our installations should be similar to the designers and engineers, so we should have no trouble , right ?
Edit: The fuel I used was Powermaster 20/20

RE: Saito 220 installed in Giant U-Can-Do 3d
I had the UCanDo60 with a Saito 100 on it...
I had to adjust the tank to be even with the carb for best performance and once I did it was a well behaved engine.
Also, once I started using 30% Heli fuel I never looked back. All the engines I used it on performed night and day against 15%. Idled lower, transitioned faster and top end RPM increased 800-1000 rpm. WOuld take a nominally powered Funtana 90 or 68" EF Yak and make a nicely powered aircraft with better idle & transition.
I don't fly a lot of glow anymore so the higher cost of the fuel isn't really an issue. But when I do fly I wanted the max performance.

RE: Saito 220 installed in Giant U-Can-Do 3d
Yep... on the 15% I started with it was always wanting to die at low idle so I had to bump up the throttle to idle higher than I like.... Then the transition was always a little "coughy". This for a couple of gallons til it all loosened up and it got better and the idle could be lowered and transition smoothed out.
Interesting enough, on a new engine that I ran in with 15%, then switched to 30%, it was like going from a tight new engine, to a well run in beast. It would idle real low from the get go and transition so smooth and fast it was great.
I'm speaking now of the Saito 1.80. I had a review to finish and couldn't wait til the engine "broke in proper". SO I had heard about the 30% and when I tried it... well... as I said... I never looked back.
I still run a couple tanks through it of 15% just to "get things going" but fly with 30%.
The wrod at our field was that the needed a good bit of time to break in. Well... 30% shortcut that for me. A brand new 1.80 was VERY well behvaed on the 30%

RE: Saito 220 installed in Giant U-Can-Do 3d
I have a recommendation for those with the GUCD!
I have the GUCD with a Saito 180 on it (inverted). I have pretty much solved the issue of flooding and dead sticks. I added a heli saddle tank (located port side right next to the cowel- mounted externally). The saddle tank provides two HUGE advantages. The first is the saddle tank captures ANY air bubbles that would otherwise go into the carb. The second is I have a plastic fuel line cut off (the kind you pinch) on the fuel line that goes between the saddle tank and carb. When I'm not flying, I just pinch it closed. Right when I start it I'll un-pinch the line to allow fuel flow.
The Saddle tank is a HUGE improvement as it assists in providing perfect and consistant fuel flow to your carb. I get nuts with my GUCD inverted, waterfalls, inside loops, you name it.... Never once dead sticked due to air in the lines.
When I bring the GUCD in I always notice about 2 tablespoons worth of air in the saddle tank. That was air that never made it to the carb!!!!
The saddle tank on my plane was simply mounted with a good quality velcro strip, after 50+ flights, it's still stuck on perfectly!

Edit: Maybe someone has both, and can post a nice rear shot, that shows the carbs. The 220 definately has a longer intake manifold, but it's also a taller engine, so it might be a wash once it's inverted, it's hard to say without seeing them both.

RE: Saito 220 installed in Giant U-Can-Do 3d
Here are the pics....
This setup is VERY easy to install - takes 10 minutes. What I like about this setup is, the fuel line runs out the cowl so you can "pinch" it off when not in use. This also gives you a visable 2oz fuel reserve!
As I said before... No matter how insane the 3D- no dead sticks!
As far as the fuel tank being higher than the carb... No way to get around it without moving the fuel tank. My setup, while not curing the disease, definately treats the symptoms.

RE: Saito 220 installed in Giant U-Can-Do 3d
have also installed saito 220 on gucd. used stock mount , with a 3 line, fill carb, exhaust, having saitos inverted with fuel problems, simple trick is to put a loop in your fuel line 1 inch above the spray bar , with this set up very lil flooding will happen , normally I fill start and fly, so it doesent get a chance to flood , landing at 1/2 tank or less no flooding at all, I still hand clear the moter before i add power to the glow plug and electric starter just to make sure , not real happy about the extra vibration from this 220 compared to the 180s but we will see how it breaks in . good luck

RE: Saito 220 installed in Giant U-Can-Do 3d
Hello everyone, I am wanting to purchase a new g-ucd with a new saito 180 tomorrow. A friend sent me this site on the saito 220. I am new and don't understand all that I am reading about the problems of the saito eng. I read an article on the g-ucd with a os 160 fx (dec 2005 model airplane). I love my 60 size ucd with a 100 saito, 40 size with a saito 82 and I have no problems. Should I go with the os 160? I don't need any problems. PLEASE someone call me today (sunday) on cell at 615-319-6762 gallatin, tn. Thanks, Terry.

Giant UCD with Saito 180 is PERFECT..... All you have to do with this plane is re-inforce the rudder and Elev. The only other thing to do is rig your fuel line with a shut-off.... Other than that the Saito 180 is PERFECT with this Plane. Hovers at half throttle with an 18x6W APC

RE: Saito 220 installed in Giant U-Can-Do 3d
have 220 saito in a giant u can do mounted inverted on stock mounts provided by kit, have 10 flights on plane with no problems with flooding at idle or turned off, with the stock fuel tanks location you must add a loop in your fuel line that exceeds the top of the tank , the instalation pic at the start of this post is droping directly down witch will cause flooding , and eriatic idle , quick fix , come out of the fuel tank hole on the fire wall bring your fuel line UP to meet the top of the fuel tank loop it back down to the inlet , and have a nice day, you dont need a pump you dont need a regulator, exhaust pressure is more than enough to get you the proper supply of fuel
