For those who have been asking about my G4 (that I recently updated to the G4.1 specs) and its new OS engine. Here is an update: The G4.1 has run 6 gallons of fuel through the new OS 105HZ-R now. So on to the questions about power... yeah, holy cow it has power. This thing just pulls and pulls. I'm actually finding myself "accidentally :-)" not managing collective the way I should on a nitro machine because it pulls through anything. This Raptor airframe and this motor seem to be made for each other. I had run another engine in this machine previously and it flew great, very precise, locked in and light as a feather, but with this engine things got serious.

I am running 30% nitro in it, my elevation is approx. 4500ft, and the ambient temps are hovering between 14F and 22F degrees where I fly lately. I've got the high needle now just under 1.5 turns out and the mid needle at .75 turns out. The motor comes down with the center of the back plate at about 150 degrees right now after a fairly aggressive 8.5 minute flight. I can obviously go leaner and increase the power but I am just fine leaving it where it is for now. I'm flying 700mm blades on it right now and have the governor on the CGY750 set at 2100. I will definitely try the 115 tooth gear as well but right now am running the 111 tooth main gear. I'm running +/- 14 degrees of collective on the machine right now as well as setting the CGY750 at 10 degrees of static cyclic. Climb outs are ballistic and the snappy rolls, flips and piros are a blast.

I'm still amazed at this airframe design. It is so big and commanding in the air and yet is lighter than any other 90 sized nitro I've owned or picked up. It has been through many crashes and I'm still using the original main shaft and I've never had to buy frames for a crash. The swash control system is bullet proof and sets up at a perfect mechanical neutral without any tweaking... talk about making FBL control setup a breeze.

Does everyone remember what it is like to auto a 90 class nitro? This machine just floats and floats in auto rotation, you can do whatever you want. I am having such a great time flying nitro again. When I head out to the flight line the other pilots cringe because they know I'm going to use every minute I can wring out of the thing before they get a turn again. If you really want to progress as a pilot I think one of the very best things you can do is fly nitro. When you are learning new things the long flight times mean that you get your wobbly legged part of the flight out of the way and then get a solid 6-7 minutes of progress under your belt.

Is nitro dead? No... not even close!

Don't forget to oil your screws so they won't rust. Oh, never mind, you oil them every time you fly. Don't forget to hover over that electric machine to fog oil it's screws.

I'm still a nitro fan boy.

Enjoy things that money can buy IF you don't lose the things money can't buy.

I am going to fly both this summer, A little electric, but I may concentrate on Nitro. I agree that you will learn better collective management because of the difference in power compared to electric. And I also need the flight time!

Nice write up. If you don't mind the question, what shims did you end up using with your 105 on 30%?

Yes, I definitely have the "self lubing" feature in full effect :-)

I did let my nitro supply dwindle unfortunately, and now I've cleaned out all my bottles and any at the local hobby shops. Having 5 cases on hand would be awesome!!!

The shim on the head is the one that comes pre-installed. I have not changed or added any shimming. At a lower altitude I would likely need to +shim or go to the 15% I think, but for where I'm at the 30% is working great with the default compression.

Who cares if you have to do a lil cleanup after a flight.... I think it's a lot better than charging batts all day for a lil bit of flying

Update on this guys.

I have recently been running this machine at the 8.21:1 gear ratio with a 115T main gear. It has made a significant difference in head speed maintainability. One of my flying buds said "Looks like that engine finally broke in." LOL. The OS 105 was a beast before, now it is unstoppable!

I highly recommend this tuning choice for this machine. I would imagine it will really wake up a .91 powered machine as well.

Still enjoying this nitro monster!

I have it set to 2050 and it holds right there. I also have a 2100 setting that works really well.

Sorry if this is posted somewhere already - I searched but couldn't find anything. What parts do you need to upgrade from G4 to 4.1?

why do you want to go from g4 to g4.1"

i had John Benario cut a 115T for my g4 so no need for me to go to g4.1

Agreed, I have a G4 with the Benario 115T gear in it and it works awesome, no alterations needed! I love that machine. I have another G4 that has all the 4.1 updates and it is a further refinement of an amazing machine.

Either way, the G4/4.1 airframe is incredible to fly.

Adam,

Can you weigh it for me? I am trying to decide on a new nitro machine and this machine has me very interested. By chance are you coming to the Palomar fun fly next month? My better half will be there so bring the family again and they can keep each other company...

Hmm... I had not considered it yet. Something about may 24th is ringing in my head that I better ask my coordinator for detail on, but if it is clear that could be a fun event/location :-) I'll check.

I'll get you some weight on it tonight. Seems like it is just over 9 lbs but I'll double check and see.

I'll let you know on the event, my "better half" keeps asking when we will hang out with your "better half" again LOL.
