I am wondering whether firewall is already fuel proofed, it looks slightly shiny. I have not ever had an arf already fuel proofed. Instructions refer to fuel proofing the risk areas such as cowl ring but no mention of firewall. I also consider to fiber glass the joints of the firewall, do you think it is overkill? One last question :-), I have around half inch between carburator velocity stack and firewall. Do you think I should make a large hole to the firewall so that carb can get the air from the fuse? According to the engine instructions, engine may spit out oil, so I am inclined to leave it as it is but at the same time engine is designed so that carb is suppose to slightly in the fuse. Nevertheless, this is not the case for Corsair as there is more than enough distance between prop and the firewall.

The firewall is fuel proof.As for the hole in the firewall,it can't hurt .A lot of guys say that you need it with rear exhaust eng.I'm using side exhaust and did not cut a hole and there are no problems

Not necessary with the rear carb engines regardless of exhaust position. There is enough room for the intake to breathe.
If a cowl doesnt have sufficient cooling then things change.
Add an opening thru the firewall to draw in cooler air to the carb. You can also see issues with the carb diaphram pump vapor locking so the fix is more cooling or adding a fitting to the pump cover and an air tube thru the firewall. This gives the carb its own air independent of the condition inside the cowl.
From my experience so far with a DLE 55 RA in this Corsair the basic install is just fine.

Heres a link to a thread I started for those interested in the rudder servo mod.

To Saito fg 60/84 users: How did you attach the stock spinner to the prop hub? There isn't enough space inside the spinner to use a nut..

V2rider

My Feedback: (4)

The one I have on my FG84 fits over the nut. The problem is it came from another plane I had a few years ago that had a G62 for power and I bought it used. I can't find it online anywhere. A friend thinks it came from Tru-Turn and suggested emailing Amanda there and asking if they still have them.

Rodger that!!

Thanks, I could not find Tru-turn dealer in this side of the ocean so I went for China made 6star spinner. It is slightly wider than the stock spinner and it does overflow from the prop hub but still better than nothing.

Yes very nice looking spinner. Thanks for the website as well. If you know someone who owns a lethe you can have a custom made spinner. I think if I remember correctly v2rider's spinner is turned out of 1.5" aluminum stock. Whoevermade it. Threaded the center 10mm. Not sure on pitch. They cut a recess in the bottom. About a half inch or so deep. So you can put yourprop nut and washer on. Then thread the spinner on. If I still had access to a lethe I would have helped you out. Anyway looks good. Please post pics.

I am looking for suggestions to install the cowling. I have a saito fg60 with keleo on and it is impossible to get to the screws in the back. I somehow managed to put the screws on but there is no way I can properly tighten them, so they were out after 10min flight.

I have a DLE55 in mine and I had to make a longer hex wrench that allowed me to reach the screws.The engine that your are using may require a totally different mount with screws going through the side of the cowl into hardwood blocks

Chris Nicastro

The stock ARF cowl mount is not that great. When flying mine with a DLE 55RA the cowl screws would come loose and one one flight the cowl came forward and was ruined by the prop.
I highly suggest you make a new mount and if you like take a look at my solution. After I made the modifications the cowl has never come loose and it's easier to work with.

Im currently working on a new cowl for a Saito FG84 which is just slightly larger in dia than the original. How does the FG60 fit in the stock cowl?

scubaozy

Fg60 fits perfect but now I wished I got the fg57. Would have been easier. I have now removed the ring from the cowl. I intend to glue the ring permanently onto firewall and attach the could around it with some wood blocks. Stock cowl is very soft, I might have to reinforce it.

Any pictures of your modifications would be appreciated!

I finished the modifications and also installed the dummy engine. Hope cooling will be sufficient.

You will need cut outs for the air to flow and carry the heat out

I know this is an older thread but..... I'm mounting a Saito fg 60 in this plane. Is it really necessary to have all that right thrust that's built into the fire wall?
I'd rather just Zero the thrust line if it would work ok.
Thanks.

Lifer

If you're good on the rudder and know how to coordinate your turns, yes you can get by with no right thrust.

BobH

My Feedback: (2)

None of my WWI planes have any right or down thrust and I manage ok.
I might just move the engine to the center etc.
thank you.

If you can keep a WW1 airplane going in a straight line, you'll have no problem.

Im currently flying the TF Corsair with the FG84 and with my custom engine mount its on Zero/Zero thrust line compensation. I centered the engine. Flies just fine and tracks nicely in all respects. You must be prompt on the rudder though.
I was surprised how fast the engine and 24x12 prop get on step when powering up to take off. I suspect the torque of the FG60 might be similar so be ready on rudder.

scubaozy

May I ask why you would like to remove the right/down thrust? It works fine for my Corsair with fg60.

Chris Nicastro

My Feedback: (3)

Doing so centers the engine in the cowl so there are no cam cover holes or blisters.
The 84 is too large to fit normally so I had to make a cowl from a H9 Corsair and then center the engine.

BobH

My Feedback: (2)

What Chris said. I like the engine centered in the cowl and not off to the side.
