It was a long build, being my first gas plane, and some required tinkering, but I was able to maiden my 91" Extra 300 EXP from Extreme Flight RC last weekend. Here is some footage, including the maiden take off and landing.

Extra 300 EXP maiden weekend flights (8 min 11 sec)

I still have some issues to work out with the motor and tuning...but I got a Fromeco TNC Tachometer from TopDawg Aviation so I should be good to go if I've been given the proper instructions .

Regarding the funny part of the video (you'll have to watch): It was a brand new never started motor. I did not prime the fuel line by turning the prop with the ignition off. So I had been trying to start the plane for 15 or so minutes, off and on, wondering if I had mis-remembered the choke servo switch direction. All the time the fuel was probably just slowly making its way to the carb. It was the first time I had ever started a gas or glow airplane...up until now I've only flown electric.

By the time it started, I was feeling condemned to prop flipping purgatory. My shoulder was getting sore, and I wasn't very optimistic that the next flip would work, nor the next, nor the next...since the previous umpteen thousand flips hadn't paid off. Every flip it didn't start, so I was surprised when it finally started. I was at the field alone-using a new restraint that I knew would work but still didn't quite trust. I set the camera up just in case something happened. I figured I'd at least...Continue Reading

WOOSH wall on Extreme Flight Extra 300 EXP using ele->ail mixes (0 min 0 sec)

I used an elevator to aileron mix recommended by Extreme Flight on on a 60" Extra 300 EXP.

It allowed very high speed walls at 100% elevator to aileron mix, with little to no alittude gain.

It was fun to try but I don't usually add the mix anymore. The 64" MXS from extreme flight has so much pitch authority that I never bothered to try the mix on it, but I think I am going to give it a try on the MXS and the Edge too.

These mixes would probably make for a cool woosh parachute too.

The video doesn't capture the awesomeness of the sound that is made.

But I'd recommend reinforcing the counter rotation pins if you plan to do this on the torque MKII with 15x7, 15x8, or 16x7 props, and maybe going with slightly stronger aileron servos than is recommended for whatever plane you plan to try it on. In the video I am using the first version of the Torque 4016T/500kv motor on a 15x6 prop.

I tried the mix because it was recommended by in the Extra 300 EXP manual :
Another neat set-up to try is to mix the ailerons to act as spoilerons which move in conjunction with your elevator. This mix commands both ailerons to raise as the elevator raises. I typically use this mix at 100% and put it on a switch so I can turn it on when needed and inhibit when not needed. Some folks feel this type of mix is somehow taboo. To them I say "
