Status: offline 		Well I got my 14 several months ago. Been flying it in a VQ Mustang until the radio failed.... I had just done a loop when the radio ceased, so it kept looping and looping and looping and....you get the idea.

Engine would not stop, period...Was not until it finally drifted close enough to some trees that it went in.

The 14 is now in a Boomerang Trainer...a general hack plane I am using to test everything before it goes back into a serious model. Has flown several hours since and not missed a beat.

Is about to get moved into a VQ Zero.

Only issue I had with this engine was in the mustang, and it was my own fault... I had it cowled wrong. Motor got hot and the conrod seized on the gudgeon.
New conrod and gudgeon, run it in again and redo the cowl to allow proper cooling. Been great ever since.

A friend has one in a VQ Me109. Plenty of cooling and his is going great. Neither of us can tell the difference between the 14 and the glow 82.

Another friend had a OS46 2 stroke. We worked out that the cost of the fuel he uses in 1 flight will cover us for 2-3 weeks!!!

Run them in properly, keep them cool and you won't regret getting one.

Status: offline 		OK, boys! Saito now makes a 57cc gas twin: The FG-57T! 1,500-7,000 rpm, swings a 23x10 propeller, uses 35cc of fuel per minute (at full throttle). Price: Around 147,000 yen which is unfortunately about $1,800 at current exchange rates. The ad boasts that it only costs 50 yen (about 60 cents) per flight in terms of fuel.

Is there any mounting data like mounting depth and width from crankshaft to top cylinder on this one in the advertisement? Can't find any on the Saito website.

Status: offline 		I see that Al's Hobbies (in the UK) has the FG-57T for sale (as pre-order) for a little under 1000 pounds (850 pounds excluding VAT). So that 850 pounds works out to be about $1,332 so that's not too bad...though still more than the UMS Seidel!

http://alshobbies.com/shop/lookupstock.php?pc=42387&tab=3

So, let's see, at only 60 cents per flight over X-number of flights, how many flights would we need to make to convince our wives that this is a legitimate cost-cutting expenditure? Hmmm...I don't think they covered this is high school math class!

Status: offline 		BTW, Ishimoke, one of the largest online RC shops in Japan has it listed for 108,045 yen (down from the MRSP of 150,000 yen). That's still about $1,200 at today's exchange rate but better. Laying the Rajicon Gijutsu ad's "full size" photo next to my Seidel, it looks to have roughly the same total width (so about 230mm). Too bad it's missing 5 cylinders!

Teus

 Tues,

The dimensions are as follows:

230mm wide (cap to cap)
168mm from the mounts to prop driver face
190mm from the back of the carb to the prop driver face (This will require a 25mm standoff to clear a firewall unless a hole is cut in the firewall)

Status: offline 		A twin gas from Saito is great!

I have been hoping they would come out with an engine larger than the FG-36 for 50 cc planes. I have the 36 in my Hanger 9 150 size P-51 and it's been a great motor. Much less vibration than any motor I have owned and smooth and easy to start.

I have a 24 cc tank in the plane and can fly for 40 minutes

Now I just need to find a nice home for the 57 cc motor!

How about a nice Hellcat

But I agree, the Seidel looks and sounds sooooooooooooooooo much better. They must make the Seidel in a petrol version!

I totally agree with you on these points. And it can turn a scale sized prop. I also like the fact that the two cylinders seems to be served by the one carb. So yes the FG-57T is really appealing. I'm still trying to work out where I'll get the methanol I need for the Seidel.

Down the road that will probably happen. Seidel was already making several benzin motors and UMS might follow...but not soon enough for our purposes. What you might ask yourself is how well a quality dummy engine could be fitted around the FG-57T. Bear in mind that on the EIII the engine is visible from the side too so a couple of half cylinders way up in the front of the cowl isn't quite right. On the plus side, being a twin it should hide itself well in the EIII cowl.

Hello Pete;
I'm having trouble getting a decent carb setting on my Saito FG14. It starts easy, idles well, and turns up around 9300 RPM on and APC 13x8; but not all at one needle valve setting! I cant get the high speed and the low speed needles to work together.

If i get a good top end, then the idle and mid-range is too rich, so I lean out the low end just a bit and get a smoother transition but then it quits at top speed.

I've owned all the glow Saitos and love them. This little 14 has taken up an entire day of tuning to no good result, and has caused dead stick landings a few times. I never had this much trouble with any engine in all my 50 years of model flying.

I have followed the instructions to the letter including the baseline settings with no luck.

Please help!

Now I hear that the early Saito FG14 had a carb problem so I'm not losing my touch. Can I send this one in for warranty service or will Horizon just send me a new improved carb?

Yes, the gas versions do run hatter than the glow versions, for a variety of reasons. (Less oil to carry the heat away, higher temp of the exhaust gases, etc.) We have taken some steps to help the situation by supplying a metal engine mount with each of the engines. This acts as a great heat sink to help draw heat away from the engine.

As always, it really is incumbent on us as modelers to design adequate cooling in our cowl installations for whatever engine we are running. We have been running the FG-20 in the cowl of the Blue Nose P-51 from Hangar 9 for the last 8 months with no temperature issues at all. Just be sure to have directed air to the cylinder head (the hottest part of the engine) and make sure you provide more air exit area than you do inlet area. (A ratio of at least 3:1 is minimum, 5:1 is better). And honestly the best way to do this is to reduce the inlet area rather than expand the outlet area (to a point). This usually results in a much better looking cowl (no great gaping holes) and a fast flow of fresh air to the engine.

An example of this would be to look at the baffles we used on the Hangar 9 20cc Taylorcraft.

http://www.horizonhobby.com/ProdInfo/Files/HAN4900-Manual.pdf Page 30 and page 45

By reducing the inlet area by about 80% we effectively increased the airflow over the head of the engine without having to increase the exit area - which would have resulted in this huge hole at the rear of the cowl. We also got some additional venturi effect from the air intake on the bottom of the cowl. By opening that up it actually helps to pull more fresh air across the cylinder head. Once we made these changes we had no further issues with engine cooling in that cowl.

I hope this helps.
