You have not seen a DA 200 quad at idle. Smoooooth!

Re: What servo gears for gas powered airframes

Metal and Titanium are the gears of choice for me. Karbonite gears are never to be used, as per the Hitec website, as the frequency of a gas engine will shred the gears over time. Also never "cheap" out on a throttle servo.... To many guys have done this and wonder why they have throttle control issues.... Ultimately they choice of servo and its dependability boil down to the type and size of models you fly, and more importantly how often you inspect your servos gear train for play/slop. Hitec 5645MG are my choice for the WW1 models I fly.

Contrary to popular belief an engine failure should not be cause for a crash. Lack of pilot skill is. Flying in places or at altitudes where you have no landing options is a pilot fail. In my view every RC pilot should start with a pure glider and the crashes would go down exponentially, you learn to fly the wing not the engine!

I have flown a lot of glow engines and love them especially the 4 strokes. Availability of glow fuel is a problem here so I now have 2 gas powered ones. The first with a Saito FG11 that is absolutely awesome and now I have an S Bach with a 26cc Zenoah. I have not flown it enough to form an opinion on yet.

You are never too old to try something new to you Floyd and it may surprise you!

Oh and I have plastic geared servos in my Senior with the FG11 for two years now and no issues.

Re: What servo gears for gas powered airframes

Your absolutely right. At my old club every one asked me to tune their glow engine because of the way all mine ran. I have nothing against gas but glow is all I know. Just like battery packs, I only use NIMH packs. I'm not interested in any other packs because NIMH packs are what I'm comfortable with. Keep flying and enjoy. Cheers Floyd

Re: What servo gears for gas powered airframes

BTW, floyd, nothing wrong with Glow, and similarly, nothing wrong with gas. Keep flying what you enjoy, this is what the hobby is about. But I do agree with you, tuning Gas seems to be like a black art for some, but then again all it takes is a bit of know how and things run smoothly. (Same with glow).

Re: What servo gears for gas powered airframes

I said I have a 50CC plane with a damaged firewall caused from the gas engine that was in it. The causes of most gas crashes I've seen are engine failures in flight. I've seen more gas engines fail in flight than glow in the last 30 years. I love the slime and smell of glow. Gas is cheaper than glow, but not when you crash a $1000.00 plane. I love nitro fuel, and have lots of fun with nitro. I even started blending my own nitro fuel. I guess when I can't afford $20.00 for a jug of nitro fuel I'll be done flying. But for now it's all I know, and you can't teach a old dog like me new tricks. Cheers Floyd

Floyd,

In your original post you said you had a 50cc gas plane. Wasup?

What were the causes of he crashes?

Iv'e seen more glow engines quit in flight then gas.

I use to fly "Slimers" before i saw he light! LOL!

Enya 4 Strokes were my preferred glow engines before I switched to gas.

Gas is WAY cheaper then glow.

But to each hus own as long as we are having fun. LOL!

Steve,

Nice stable of planes there, especially the Hurricane, but your Radio choice doesn't make me Calm! LOL!

Steve,

Do metal and better yet try and find Titanium Gears like a Savox SV-1270TG High Voltage Monster Torque Titanium Gear Digital Servo.

Don't know how much Torque you need.

I fly IMAC 35cc to 170cc Airframes for 15+ years and have been using Savox for about the last 6 years and find them quite reliable.

Don't chintz out on servos when you've spent all that time and money building the airframe.

Floyd I don't know who's tuning your engines but even my DA85 and DA120, notoriously labelled as bone shakers, are smooth. I't's all in the tuning. You can leave a gas lawn mower at factory needle settings but you should be tuning your model airplane gas engines. LOL!
