I am using the saito Fg90-r3. It only has about 5 tanks through it. Runs strong, Not sure why it quit but I was throttled back at the time and should not have been with this plane.

Kevin,
Sorry to hear about the stall.
I was lucky when I first flew my corsair that I had other giant scale pilots reminding me that this is a Warbird and must be flown like one.
Airspeed, airspeed AIRSPEED at ALL times. This taught me to always land high & hot. I drop my gear on the gear pass, drop my flaps to full as I'm turning from base to final while dropping 50 feet towards the runway.(Airspeed) the Corsair bleeds off the speed as the wheels touch.
If I'm dead stick, then I leave the gear up and belly it. I've bent too many sets of gear trying to set it on the wheels when there's not enough AirSpeed.
Luckily its an ARF and you can just throw more parts at it! (just kidding)
How did you FG90-R3 hold up?

I'm still trying to get your FG60-R3 to run smoothly!

Your expreince is quite different from mine. I find the Corsair a real ***** cat on landing and have made slow landings dragging it on touch down with the nose up and a bit of power. Wondering where you have your CG. Miner is on the rear most recommendation.

Hey Scott,
I was definitely slower than I should have been on the landing but it did not stall as much as just drop when the engine quit.
It came down on the gear, thankful it stayed level and did not hit a tip first.
Did not even get any dirt in the cowl.
The engine was running fine throughout the flight.
I have not run it since but it does turnover fine so I do not think anything in the engine broke.
I will spend a bit more time on the ground tuning and testing before I fly again.
I had a guy getting video of the flight, when I get it I will post it. I think he is editing out some language issues.
When I review the Video it may show I have it all wrong.

Dont get me wrong, my Hog could slow up for 3 pointers, in fact I've flown it backwards in a strong wind. It's just that I've learned not to rely on the engine so if it quits I still have the kinetic energy to safely land.

Kevin, did you run the FG60 when you had it?

Scott,
Yes I ran two break-in tanks through it.
I never tried to tune it.

Makes sense. I've never been concerned about the engine on mine and had I been, I'd likely follow your method or change the engine.

Has anyone had good luck with the Saito FG90r3? When I ask about it with more experienced pilots than myself, I don't get the best feed back. One pilot tells me that a pilot he knows brought a spare with him to Top Gun - and needed it!!
Last week a gentleman was maidening his Corsair and another experienced pilot made the comment that "well that engine might last 5 flights before needing repair!" And now Kevin mentioned he had his quit on him after 5 tanks.
So I was just wondering - has anyone had good luck with the Saito FG90r3?

Hi Harry
I have the FG 90 in my H9 Corsair, no problems at all.. 10 flights so far, runs great I use about 5% oil in the fuel, and fat mixture setting...
Regards Dan

Dan - That's good to hear. Wish it was over 50 flights but that is the best success story I have heard so far. What brand of oil are you using? Is a fat mixture the same as a rich mixture?

hi guys have been flicking thru this forum as for the past 8 months i have been putting the h9 corsair together,i waited for the saito fg90 to come out due to the issues with the 84 so far have put 4 litres of fuel thru running it in using klotz oil at 20:1 as reccomeded and with keleo ring.
have still abit to do prior to maiden flight but would love some pointers as to the flight characteristics,ie how much flap on take off,with flaps for landing do you have a elevator mix dialed in if it tends to pitch with the flaps,any info be appreciated this has been one expensive bird,im flying a hangar 9 beast 100cc and that thing is on like rails floats in for landings etc.
years ago i had a byron original corsair that flew not to bad had to land fast as i remember but it was alot lighter plane than the h9,like i said any info be appreciated,thanks

Hello Dieselnz,
I've had the Byrons Corsair and the H9 Corsair.
I had over 50 flights on my Byrons and I was it's 4th owner. It was 23# on a tired Q52 and I could land it anywhere.
Full flaps were 50-60 degrees and I dropped them on a 2 second extension as I turned final while keeping the nose down and only leveling off to touch the wheels to the runway.
If you're building the H9 much heavier, (many run between 28# to 35#) then you need to keep the speed up.If you are flying the heavier bird, then 10 degrees of take-off flaps are normal.

Scott

cheers for the info,its been many years since i had the byron corsair,have no idea of weight on the h9 corsair as yet will all depend if i need to add ballast with c.o.g,im not too concerned on takeoff,my main query is how the plane handles when in flight and the flaps get deployed,i have had some planes that need quite alot of elevator to compensate and others that need nothing,i will have the flaps on a 3 stage switch,first 2 positions will be for flight then the last position will be full down for display as dont they look great fully down and split apart.....cheers for the info,im not normally this concerned for a maiden,even the h9 beast i had no issues gettn it up asap but knew it would fly well,,,this corsair not going to have the same confidence,,,,,thanks

Not quit 50 yet, but got 20 flights now.. No problems at all, run great.. Im using Castrol Power 1 racing oil, and fat/rich mixture

Does anyone have any videos, pics, or additional flight reports with the eme 70?

Flew my H9 Corsair with the EME70 to its 132nd flight, the center wing section failed on the 133rd resulting on a total and absolute destruction.
The EME70 performed great, never had any issues. Finishing a Byron Corsair now and selected the EME70 again for power.

dieselnz

hi flyingchef,so gutted to see the demise of the corsair,you say that the centre wing failed,i have heard of a couple incidents of this happening{one on its maiden flight} and have been thinking of a way of adding more support to fixing it to the fuselage as there is alot of weight in that centre wing section which is my guess the reason of it failing can just imagine that in the likes of performing a loop there would be alot of force trying to pull that centre wing away from the fuselage.
any one feel free to jump in with ideas of adding more support between the centre wing to fuse,alot of people who have seen my corsair have commentated on the weight of the centre wing,this has been the most expensive plane i have ever put together i stopped adding it up when it exceeded $10,000 so any ideas be appreciated,rekon im about 2-3 months away from a nervous maiden flight,i fly a hangar 9 beast 100cc and was not nervous putting that up for its maiden,it flies like its on rails but know the corsair will be nothing like it.
one thing i really would like to know when setting up to land and flaps are deployed does it require a mix for elevator as well,some models i have flown need elevator mixed in with flap and others have not needed any,my byron corsair was too long ago to remember if i had any elevator mixed in or not,cheers.

spitfire66

That is devastating. Sorry for your loss. Do you think the wing dowels failed or was it something else? I have an earlier production corsair and not sure if they ever modified anything on the newer center sections. Were you able to find any clues as to what happened? Were you maneuvering aggressively? I am definitely interested in anything else you have to say.

Hey guys! I know I posted a while ago, but just got to the maiden flight on my Corsair on Monday. I am quite happy with how it flew! Took absolutely no trim and flew straight and level hands off. I have the FG-84R3 in it and it is bone stock. It actually runs really well and I have not had any of the mid-range issues that others have reported. The temps are close, but #1 cylinder was just a little warmer. I will try and get exact temps with my next flights. I have the Robart air retracts installed, Hitec servos, dual 12oz fuel tanks to make it all fit with the FG-84. Need to do some finish work just to get gear doors and such finished, but it is almost there. Also switched to Futaba here before the maiden so it took a little longer to get everything setup again. But I am very glad I switched! Cant wait to fly it again!

I just ordered the Saito FG90r3 for my Corsair. For those using the same engine, I was wondering what prop you used for break-in and what prop you are using for every day flying? Thanks

Marguet28

I have a 90 and used à 24/12 for break in. 6000 on the bench after 5 liters. Run fine. Don't forget to add oil before the first start into the nipple.
for the flight still wondering which sizes....

heirmeistr

My Feedback: (2)

I am not sure what you are referring to. Will the nipple be obvious when I receive the engine?

Marguet28

Just add oil into the engine before the first start by the nipple.
