I was using the old 4.8 NIMH packs but I read somewhere that if the voltage drops down below 4V on the Spektrum receivers you could experience some brown out issues. so to be safe I went to 6V and have had no problems since. I put another RX in and range tested it so hopefully it was a faulty RX. We will find out tonight.

O.S? We ain't go no O.S., we don't got to show you no stinking O.S.!



(Truth be know I have a lot of old 2 stroke O.S. max engines and love them all.) My first 4 cycle was the open pushrod model when it first came out from O.S. I dropped out of the hobby for awhile due to life and came back in 2004. Since that time my 4 strokes have all been Saito due to cost.

OK I'll break this one down.

Since I already know that 28 = 82.04 I'll just move the decimal point so 9/5 of .28 = .5.

So... 25/5 = 5 X 9 = 45 + 32 = 77 + .5 = 77.5 F

I moved to 5 cell packs (no mater NiCad or NiMh) several years ago after almost loosing a plane ON THE GROUND when a cell dropped out. The next time I had a cell drop out, I noted that the Pitts was flying funkie and being difficult, so I landed and checked the voltage to discover I was flying on 4 out of 5 cells. Now ALL my flying packs are 5 cell or A123's. LiPo's get a BEC so they don't count.

On engines, I have some really good ASP's. I got them straight from the factory, that is I collected them from the people who built them. Most are undergoing "modification" mostly to diesel but some to go REALLY fast. The diesels get an OS 1a carby and internal mods along with a "button" head for compression adjustment. My 32 gets 8 minute engine run turning a 10x6 prop on 8 mls of fuel. On Saitos I am experimenting with fuel combos in a new 62 to see what performance I can get for Duration (vertical drag racing). Using a non pumped engine (YS) I get an additional 5 seconds of engine run. Any way we are starting at 25% nitro, Coolpower heli oil and a 12 x 6 Bolly carbon prop. Let you know what happens.

See? that's what i like about you

Trev since it's so quiet thought i'd mention rubber and saito's together mate.We've just had a freaky summers day in the middle of winter so hit the duke starter button(here's the saito bit,the small block 82 on good nitro and glow ignition at idle sounds just as lumpy as the duke) and off to scrub some michelin pilot sport 4 radials in.If getting old means you can try these tyres that's awesome for any motorcycle rider who remembers the dodgy treaded dunlops we rode on back in the day of japanese two strokes with frames made from rolled up chicken wire and explosively powerful engines.The tyres we have now are more than twice as good as the old slicks you used to race on and good side grip even when cold.I hope dying and going to heaven or hell is this good.

Old Fart a similar thing (re tyres) in tin tops. I had the experience a few years ago of driving a Bathurst GTS 350 Monaro on "modern" tyres at QLD Raceway (Willow bank) and I scared the s#*t out of both myself and a couple of up and comers from a popular race team with how well / fast the beast went and the statement so much for modern technology was bandied out a bit in the pits. I worked with the guy who bout Ducatis back into Oz in the late 70's or was it early 80's, one Bobby Simpson, he was an aviation "cone head" at Ansett. Fun for me in those days was any one of the following an XU1, an A9X, XY GTHO, or a Bathurst 350 and just as an aside a full factory spec 240z, and then I got married, such is life to quote a well known Australian. I am off to Cairns tomorrow to take the gospel of O/T flying back to FNQ and also to warm up for a week or so. Catch ya on the flip side.

Well I have 2 OS, and just got back a bit ago from the field to maiden my Somethin Extra with the newly acquired used OS 70. It purrs and roars. Good running engine, sounded like a harley at low idle. I maxed out servo travel trying to find the kill point, which has the throttle fully closed, and I still had to pinch the line to get it to stop, which took at least 30 seconds. My other OS is a 52, which last time out I did a little tweak to the LSN and it is running so much better now. That one I got with about a tank through it used, and it is finally broken in.

I still prefer the Saito engines though, they just SOUND better!

Morning guys. If l can fuger how to post pick, l will. My wife bought me a Stinson Reliant from Hobby King for my birthday. It has a 85.5ln, Ws it to be a 30cc gas plane. l'm installing a Saito .91. Whats net about this plane is that it has a two peace wing on a tub, removable stab, doors on both sides, windshild comes out to service gas tank or ? But the best part is that it was $263.00 to my door! (Bought from HK east) our Arkasas store. HK has two, a yellow ans blue one and a red white and red one. Only the white and red one has flaps, nav lights, hinged doors, (The yellow one, you screw the door in. I'm making hinges for mine) latches for doors and ladders and more. But! it also coust about $50.00 more and l can make my own. Ck, it out at HK, it's well built.

Just got back from a scale rally and of course the Saitos performed flawlessly. The rebuilt 100 in the Super 'Bolt darned near hangs on the prop now and the 125 Waco is always a crowd pleaser.

I ended up using a gallon of Cool Power 15% synth and am impressed with how little I need to clean the airframe. Do miss the smoke from the Witches Brew telling me I am running adequate mixture, though.

Bill, I used 5 cell NiMH packs for quite a while and the biggest negative was their self-discharge rate. Pretty much guaranteed I had to rewind them the night before.

After experience swapping out my Tx packs, all my new installations now sport 2S LiFE and I can let them go for months with little drop when I check them beforehand. No issues even with non-digital servos and they have the push to work with servoless retracts. You just need a good charger that can display total capacity in percent to get an idea over time of how long they will last before you need to rewind them again.

NOTE: I also now include digital displays in all my airframes to show the all-important cell balance. You can leave them permanently connected with a N.O. pushbutton on the negative lead as this setup does not draw any current until that is closed and active. A couple of pics of the Waco to show how it works.

I also add a flashing LED to let me know when the flight system is powered, (draws less than 100 mA). Helps if I forget to shut it down. You can see it just above the locking A/C rated toggle.

Just re-expressing it as I remember: FWIW
F = (9/5 x C) + 32
C= 5/9 x (F - 32)

Boiling = 100 C = 212 F
Freezing = 0 C = 32 F
Room temperature (?) = 22 C = 71.6 F

Do you know what "cold enough to freeze the balls off of a brass monkey" really means?

Sincerely, Richard

Slammy nice looking stinson.Call me an overpowered fool but i've got an 82" taylorcraft with a 182 twin in it,it's not overpowered.Could you get hold of dave's old high comp 150 to use in it? and tell him he can keep the spark ignition,you'll have glow thanks.No stress you can thank me later

Yeah you do, this is said engine, it was a Christmas gift from my daughter in or around 1992, can't part with it and the ignition system is a great asset. I can actually run my little Saito .30 on ignition with a home made bracket. The 1.00 twin will get C&H Ignition next. The center picture is my high compression, (15.5 to 1) Saito .80.

An FA-91 won't be near enough engine for that plane. An FA-180 would be more like it.

What in your opinion is the sweet spot as far as airplane size for a FA-91?
