Saito FG-60R3
 

Starting a new thread for the Saito FG-60R3. Based on the comment below, it looks like this version of the Saito gas radial features the intake plenum and conrod bushing mods which have address the short comings with the FG-33R3 and the FG-84R3.

Definitely interested in this bad boy!

Dave

Yeah, I'm still waiting to see it listed on horizonhobby.com :)

Shouldn't be long. Street price will be $1179.99.

right on!

I don't think so, the FG-33R3 is currently listed on HH site at $1229.99. I bet the FG-60R3 will be listed some where between $1400.00 to $1550.00usd!!

I may have mispoken, my apologies. $1199.99 is more accurate.

Craig

Craig, no need to apologize, you didn't mis-speak, you just mis-typed. I cannot believe that HH would bring a brand new FG-60R3 to market and sell it for $1199.99 when the FG30R3 is listed at $1229.99. It just sounds too good to be true!!

Hi All.

Speaking as an 'ex' Saito fan (of a couple of decades) you may wish to hold fire with this engine
and see how it performs before spending a rather large sum of money.

It might also be worth reading the numerous threads on the FG series....to see what
you might expect performance wise.

happy landings...
AM6.

Yeah - I have a FG-33R3 with the mods which are now included on the FG-60 and I love it! Looking forward to the bigger version!

Cheers

Here's a shot of the master rod bushing.

Right on!

looking forward to picking this up! But, admittedly, I'm struggling with airframe selection for this size radial engine. Anything new coming down the H9 pipeline suited for this bad boy?

Cheers

Hi Mark,

I noticed you mentioned the mods. Has it in fact been confirmed that the Ray English mods have been adopted by Saito.
I have a Bates Hawker Tempest that this power plant would be perfect in, but would like to wait until the mods have been confirmed first.

thx
Dave

Post #11 confirms the addition of the master rod bushing. As of this writing only the FG-60R3 has the bushing in production.

Craig
Horizon Hobby

Thanks for getting back to me.
I will go to the website to order one.

thx
Dave

Live on the Horizon Hobby website today, the image will be added soon. Expected to be available around December 10th.

Learned today that the Keleo exhaust ring is now available for the FG-60R3!

In france, I received my Saito FG60 R3 last week. I ordered a Keleo exhaust.
You can follow my thread here, with pictures and a video soon:

Looks fantastic!

So who is on the list to get the 60R3 when they arrive in Dec. I'm on the list.
T

CRG, is the scheduled arrival of this motor still on track? hope there are no delays like the people who have been waiting for the Evolution 60FI motor. I just ordered the Keleo ring for this motor. really looking forward to getting it. Merry Christmas to me.
Tom

Hi Tom,

Yes FG-60R3s are on schedule. I don't have a precise date but it should be somewhere around December 8th.

Craig

What airframe did you decide on? Looks like the FG-60R3 should turn a good size prop!

Cheers

I would like to put it on a Sopwith pup kit that I have. Or an ARF, P-47

I received my Keleo Exhaust:

That sounds absolutely fantastic, thanks for sharing.
The difference in the exhaust sound from an open cowl stock exhaust to a
closed cowl Keleo exhaust is tremendous!
I,m saving for one of these bad boys for my TF GS P-47, I just hope it fits in the cowl.

Dave

Awesome!

Already get one from Keleo here in Japan,
I can't wait to hear the good sound....LoL.http://www.rcuniverse.com/forum/atta...mentid=2049725http://www.rcuniverse.com/forum/atta...mentid=2049726

I also received the engine a few days ago. Destined to be installed in an 86" Top Flite FW190.

(I am copying below some of the comments I also wrote over in the TF FW190 thread)

Most people go for the FG-84 for the FW190. However, I opted out because of certain design problems reported here (not fatal, but nevertheless annoying, for a 1.5k motor...)

Plus, the FG60 has a 220mm diameter which will fit most warbirds in the 80inch/50cc size range.
The same cannot be said for the FG84 (only seems to fit the TF FW190 and the H9 corsair without cowl hacking).
Anyhow, my next bird will be a TF Zero and this fits perfectly - the other major deciding factor.

If I may put my 0.02 on the table:
- The 84 uses 3x1.80 cylinders to swing a 24x10 @ low-mid 6,000's for a thrust of ~36lbs but has this inlet design issue which makes it underpowered relative to the new FG60 engine @ 5.7HP/3.057kg = 1.86HP/kg. After the Ray English mods, this index would climb to more than 2.2HP/kg (or 20%).

- The 60 uses 3x1.20 cylinders to swing a 22x10 @ mid 6,000's for a thrust of ~26lbs but has better power for its weight @ 4.7HP/2.090kg = 2.19HP/kg. Based on the above calculation for the modified FG84, this result is an indication that Ray's improved design changes have been included - plus the bronze bush for the master conrod as a Horizon rep has confirmed somewhere else here in RCU.

- Saito will probably never acknowledge the FG84's design shortcomings as this would entail warantee work on existing engines out there. I think they will just phase it out gradually.

- Instead, I see them releasing a "New!" FG75R3 in the future with 1.50 size cylinders (just to be different to the 84), same diameter and power-to-weight ratio as the FG60, but now able to swing an 23x10 @ mid 6,000s for a thrust of ~30-32lbs.

If you think about it, most 50cc warbirds (and especially the new mass market ARF breed which is light) come out in the 24-32lbs range; the FG75 would pull a heavy bird with 1-1 thrust to weight ratio... Perfect combination - and would fit most cowls. The would then be the definitive 50cc warbird radial..

So, if life were not too short, I would wait a bit longer. For now, the FG60 will do nicely if I manage to keep the 190's weight down to about 24-25lbs.

A test stand was first constructed for the break-in runs.

Then, tappet lubrication and clearances were checked over on the engine itself. I found 3 tappets completely dry and one out of spec (>0.1mm gap). Easily re-adjusted and oiled with some 3-in-1.
Some 3-in-1 was also injected into the crankcase via the breather nipple just to be sure (I avoided opening up the new engine to check lubrication).

Saito elbows (included) were installed with some high-temp gasket sealant to avoid blowing muck all over the new motor.

Mοtor was finally mounted on the stand. An APC 22x10 was reamed @ 10mm and installed along with the Top Flite Spinner included in the FW190. Tank was 500cc.

Initial runs here:

its almost the end of the first week in dec. the motor was to hit the first week, if there is a rep watching this thread, you got any news for us who have one on order. I have already ordered my Keleo ring. please don't tell me this will turn into the EFI engine nightmare.

Saito fg60r3
 

Thanks for the vid.
It looks like its running really well.

Dave

It's getting better by the minute! Seems like No.3 is too rich, while No.1 is slightly lean and No.2 somewhere in between.
Trick is to make No.3 run consistently (i.e. lean-er) without overleaning No.1 (risk of seizure).

One of the tricks I have tried in other Saito multis is to remove the ignition from the lean cylinder which is firing/is hot to allow the rich /non-firing/cold one to start firing and thereby expand and seal/seat the ring a bit better. Caution: not for prolonged periods! This rebalances the "unbroken-in" cylinders a bit faster..

Anyhow, I will follow closely the suggeted procedure in the manual (WOT <4,000), seems to allow the engine to improve rapidly (i.e. all cylinders firing but without risk of overheating).

FYI: Low needle is dominant, I was trying to richen the engine with the High but to no avail... a couple of turns on the low made all the difference.

Keleo is on the way - looking fwd to the difference in sound!

Keleo arrived and mounted. It works. ;)

Wow...looks and sounds fantastic!

Cheers!

considering putting one in top flite p-47 arf, will it fit?

I too am considering the 60R3 for a TF P-47 even taking the step to make up a template to see if it will fit.
The template I made doesn't, so we will have to wait and see if someone with the engine in hand tries one out.

Dave

Engines are here!!!
 

They are here! Just ordered one up and got the shipping notification that it's on its way... they had 10% off sale and I pounced ;-) Can't wait to hold and caress this baby! :cool:

Mine also is on the way, first is to take it apart and inspect. Merry Christmas to me! First flight will be the new Extreme Flight, 91" Yak. Can't wait.
