Hold my beer and listen to this

Ok, this is my story, No BS.
I think that the 104 extra 300 V2 is the finest ARF I have ever built. but I have had some problems in flying it. seemed to drop a wing in hard turns and hard elevator throws. and I never trusted flying it low because it seem to drop out unexpectedly. First thing I did was to change out the elev servos, then made sure all the wires and the 2 -5k lipo were up to par. checked the wing incident, made sure the elev were moving the same speed and together. I have been tuning engines for a long time, but to make sure I took a copy of Terry Willis how to tune your engine and spent about 5 flights re tuning it. I have other planes that fly so great, and hover like they are hanging from a rope. just could not get this plane to work for me. always seem that I could not find a good speed to fly the plane. So today I headed out to fly and decided to take it. I was out of gas and my favorite oil, (dont want to start an oil war again) it is a type that is widely used. But the only oil I had was redline, So I mixed up some. 40:1, at the end of 5 flights the engine ran so smooth, that it made the plane fly real great. I can bring it down right in front of my face. I tell you the truth, i was thinking about selling the air frame. I just cannot believer how a smooth running engine can make that big of difference. I am a happy boy now.

I know that sounds crazy, but it true. I guess I was fighting the engine, and the throttle transition.
I have a DA70 that run so good and smooth. now my DA120 runs that way. tg

I know for me... I Also like a soft throttle curve from just off idle all the way to half throttle.. half to full I just get it as linear as I can and that helps me when I’m doing stuff on the deck

I have one of these babies on the bench early for next season. It will be my backup IMAC plane, but primarily it will be the fun plane. If I decide to go with canisters for noise, how well does the plane carry the extra weight? Am I really going to notice?

Note, I am NOT an all low and slow 3D flyer. I dabble in 3D. Most of my fun flying is a lot of snaps, slow rolls, knife edge spins, occasional rolling harriers, and such. I could care less about rocket pull outs from a hover, but I do want to be able to do a crank shafts, blenders, and pop tops.
