Saito 82 in the Tony

Just got back from the flying field and flew the Tony KI-61 with the Saito 82.It is 6grams lighter than the 72. Used the same prop but it turns it faster.I needed that because of the 4400ft.Altitude here in Salt lake. It ran great. The prop is a Brian Eather 13.25 Dia.and 4.7pitch. Lap times was 5.2.the venturi hole is .285 Steve Moons Manifold.So if your going to run an 82 I hope this info will help.

Gordan,

Godzilla has been complaining about vibration, How do you rate the vibration and power? Will it definitely be an upgrade to Saito 72 size airplanes? How did it fit?

thanks.

Please do not use me as an example. My airplanes are simply not beefy enough in the front end. I have been having ongoing problems with this. I am going to remedy the probblem in the next series with carbon fibre.

This is all I have to say. Using the prop I am currently using the runs I was getting this weekends were in may ways equal or superior to the 82. The 82 definately seems to to run hotter and will need more beef up front than the standard 1/32" plywood doubler nose.

How did it fit?

It is the same.

As far as vibration I didn`t notice any more than the Saito 72. I`m using 1/32 plywood doublers and 1/2by1/2 motor mounts which is cut down to 1/8 in.after it goes through the front plywood firewall and then 1/8 the rest of the way back to the wing.The Tony weighs 69.2oz.and has 743sq.inches.It ran very good and had no problems with over heating.The temp.was 82 to 85 deg.It ran steady the whole flight.I think it is going to be a good shoe in for the 72 for those who feel they need the extra power.Just my opinion which sometimes don`t count.All in all I like the 82.

Gordie,
What tank and how big does it have to be?
Alan

Alan,

I use a six ounce tank.At 4400ft.I use 4 1/2 ounces of fuel it runs 6 1/2 minutes.At sea level it will use 4 3/4 ounces. I also use a r/c plastic clunk tank, plumed uniflow.Runs are very steady. Hope this helps.

PS. Missed you at Northwest regionals this year.Hope to see you at the nats.

>I also use a r/c plastic clunk tank, plumbed uniflow.

Really? How is it plumbed?

Gordie,
Yea I missed everyone. New job kept me away. Won't be at the Nats either. Maybe next years Regionals. Can't make it down to the Golden State as I'll be on Vancouver Island on a boat building project. Sure wish retirement would get here.

I too have run the 82. In my 62 oz Mustang, it is WAY WAY too much motor. The vibration level was higher than the 72, and it DID turn the prop faster (no surprise here). With some time (which I don't have right now) it might work out well. I will try more when back from the NAT's.

In it's current state, the 72 was WAY superior in all aspects. I was flying in a STRONG wind and the 72 worked very well, and the 82 was at best questionable. This is not a fault of the engine, but more of finding all the right parameters necessary to make this engine (the 82)function properly in that model.

Now Gordy's plane may be a perfect fit right off the board. It is bigger, heavier and at altitude and that may be the key to that combination.

See you all at the NAT's.
