That crappy 2 stroke sound is why I plopped down $600 and change for that 120R3 yesterday. I have been holding off on finishing the plane because I didn't want to put the DLE 20 on it. Not only will it have the sweet 4 stroke Saito sound, but will have it tripled. Once I get it, will have to figure out a way to route the stacks to come out the scale locations.

Speaking of starters, I finally got around to replacing the dead Nicad pack on mine with a Lipo. I found one that fits the case perfectly and now have plenty of power to start all my engines.

Are you using a 3 cell or 4 cell LiPo?

I used a LiPo in this gear reduction starter a few years ago. A 3s hard shell. Also used a 50 amp relay instead of the push button to handle the high current switching.

Reward, if found So far, the best combo I have used. The 20 volt LiOn Dewalt batteries are amazing. The extra 6 volts is most welcome and the batteries are easy to charge and a snap to swap out One charge lasts for weeks.
Super cool Gary. Looks purpose built. Wonder if my dozens of milwaukee 18 volt fuel batteries would work.
Great idea. I have been velcro attaching 4 s lipos to my three sullivan's, works ok but....
Hopefully the moron thief loosened the prop with the starter and got a nice dent in his or her face for the bad behavior.

I have a spare Sullivan starter but I need to order replacement plastic ends it got dropped. I think I would like to try and convert it to use the battery from one of my power tools.

3S, a 4S wouldn't fit in the case. I was able to get the 3s in by trimming some of the baffles away inside the case that held the nicads in place. It has a lot more oomph to it than the other identical one has connected to the power panel and AGM battery. Shorter heavier gauge wire did the trick.

Count me in with using tool batteries on starters. Even though this cheapo starter will spin up big block Saitos and twins I need to find a higher quality starter. The brush holders in this one melted enough to stop the brush from moving as freely as it should. A tap or two on the bench will get it working but I need something better.

Today I flew the Saito 120 Fat Head I got from Gary. I got in 3 flights on my scaled up BUSA Stick about 25 minutes each. The carb on that engine is impressive. I can slam it from low speed to full speed without a problem. I was playing way up high flying just above a stall on the last flight and the engine would react with power as soon as I needed it. I was concerned that I would need exhaust pressure to the tank because there is no pressure tap on the exhaust. It was not a problem running on suction only. I think my Saito 120 Dual Plug engine is just a tad stronger and lighter but for this plane the Fat Head is perfect. I posted pictures of the plane a few pages back and it flies like a huge trainer with a high lift wing. I can drop both ailerons like flaps if wanted. On a breezy day I can get it to stand still in the air and twice I’ve got it to fly backwards. So, the Fat Head Saito 120 is a perfect match for this plane and is going to stay on it.

Pedro 😊

That's awesome Pedro, nothing quite like flying backwards in a headwind.

Great match up there Pedro. Love to hear follow up reports like that,
The more you run those beauties, the more you like them.

The more I fly any Saito the more I like them. The more I run my YS91 the more I hate it. Now it has ruined a new set of bearings burning less than 1 gl of fuel. Pile!!

Dave, I'm beginning to get the picture.

Looks like molded foam I'll bet it doesn't weigh much at all.

Very lightweight foam. Highly detailed. No Soul...

Pedro i had a few conversations about tank pressure v no tank pressure. None is fine if you fly a model gently and as you know you are a lot fatter on the main needle. Any violent aerobatic flying needs tank pressure or the engine gets the flu and coughs a lot.

Never owned a foamie but gee willickers there's almost no cleaning up after a fatal, just pick your engine up and go home.

Pete, this plane flies like a huge trainer so I'm not doing any violent moves. I think the engine is perfect for it. I put in a couple more flights yesterday after I posted how well the engine runs. I've now burned a half a gallon of fuel through it just floating around in the air. I really like doing touch and goes with it and never letting the tail wheel touch the ground.

Big grins here. A nice, smooth landing or touch and go with tail up is one of the prettiest things a plane can do.

My LT-40 does that day in and out. I get the tail up on take off and let it roll down the runway on mains only too. Last time out I landed it on one wheel and rolled down the runway like that. Landed too fast. I kicked left rudder and spun it 90* to use the main runway way to slow it down. Of all the planes I have, the LT-40 and somethin xtra are the ones I fly the most. Both are saito powered. Now that I think about it, most of my planes are saito. I have two DLE in the bigger ones, and a YS in the Liberty Sport, but all the rest are saito.

You gents mentioned CRS a while back, I stumbled across this 100 GK that I forget about, what a terrible thing to forget and a wonderful thing to remember.

The 100 GK looks great on a Cub.

Yessir,


Many of the high wing, trainer type planes are good at tail up landings. One of my personal favorites is the very old Kadet Sr converted to taildragger configuration.. Build it light and no stinking ailerons, loads of flying fun.
Kadet Sr done up as an LT-40:
