Default Extra 300LX #18

Well here she is basking in the sun. Extra 300LX #18 is for the most part ready to go. Just waitin on the battery install and balancing. Oh and some SWB servo arms. I started with the HD dubro arms and sullivan clevises but they seemed like they had a whole lot more slop than expected. Can't wait to get her up in the air and find out for myself what all the hipe is about. For the most part a very easy ARF to put together. My many Thanks to Tom and Wildhare RC. Hope she flies as good as she looks!!!

Green grass in MT at this time of the year? how did you pull that off? Glad you liked the plane can't wait for the flight reports, I just bought another G-62 so I can order the 300.

We have had a really warm spring. The experts say that our melting snowpack is a month ahead of schedule. Its shaping up to be another nasty fire season. We have had some rain this spring but not even close to being enough. However on the other side of things it has made for some great flying days.

Well fellas :
She has flown her first two flights last night! And all I can say is that she has broken the needle off of the AWESOME meter!! AUW is around 18 lbs on my bathroom scale. Setup is
3 1800 6 volt nimh batteries
3 switches
4 5945's
1 8611
brison 3.2 swinging 22x8 Zinger Pro
JR PCM reciever
Basically the same setup as everybody else. Only took one click of left aileron to trim it out for level flight. Didn't get real crazy with it. I'm still trying to master my hovering, but I think this plane makes it easy. Had her hovering for 10 or 15 seconds on LOW rates. Probably around half throttle to keep her hanging. Pulled out plenty good enough for me. Inverted flight only took a touch of down elevator to keep her level. Didn't think to try any harriers or waterfalls was having to much fun just watching her fly. Did a few knife edge passes and looks like it tucks to the belly a little. As far as landings go, I think it lands better than any trainer that I have flown. Very smooth flier. All in all for a first gasser. This is an outstanding plane. Tom you have done one heck of a job! You've got me hooked on Wildhare aircraft.

Thanks. I do have a question and a comment.

Are you actually flying in Montana? I ask because I get a lot of questions from people about engines, and I'd like to know if the Brison 3.2 is being used satisfactorily at that altitude.

The tuck to the belly is one of the attributes of the 300LX version, it is much less pronounced on the 300 Special.

Tom
Yes I am flying in Montana. I am 15 miles from Glacier National Park. I have only put two flights on the plane so far. I am roughly at 3000'. The motor seems to run great. It kind of blurbles at about half throttle. So I think I need to lean out the low end just a tad. The motor came from Tenn. I had to lean out the high end a bit. Idles great at 1800 to 1900 rpm. The transition is quick and crisp. So maybe you can give some advice on my blurbling. Kind of sounds like it might be loading up a bit but it clears right up when you go to WOT. So that is why I think I need to lean out the low needle just a wee bit. As far as performance. I wouldn't say that it is a rocket ship out of hover but it does pull out with authority. I am very satisfied with the performance thus far and wouldn't hesitate a second in recommending the Brison. Hope this helps. Any more questions Tom just let me know.

Thanks, that's what I wanted.

You want the low end to be as lean as you can get it and still have good throttloe response. When it gets too lean the throttle will sag or die completely when you open it up.

Hey Flier

I have been really busy so haven't hit the forums much. The edge is flying great, I got a couple of flights in today and Its a great plane and alot of fun to fly. I bought a 80" giant scale planes Katana from lhs. I ripped the covering off and got rid of about a pound of weight, It looks like it will come in around 14.5. I'm going to try it with a zdz 40. I'm covering it now and hoping to fly it next week. Good to hear from you flier.

Keep it in the air!

Once you get the low end adjusted do the high end with a tach. This procedure assumes an engine that is broken in. If not, follow manufacturer's directions. It also assumes adequate cooling for the engine.

When checking RPMs do it from behind the prop. Never stand in front of or alongside a running engine. And be careful!This procedure is difficult to do with the cowl on, but if you can do it that way is best. Often when you peak an engine with cowl off, putting the cowl on changes the settings.

Start the engine and warm it up, then check the RPMs with a tach, write it down. Shut it down, and close the high end needle 1/8 turn (no more). Re check RPM. Write it down again.

If rpm has increased, repeat the procedure until RPM does not change or decreases. IF RPM has decreased, go the other way and open the high end needle 1/8 turn.

What you are trying to do is find the peak RPM setting, then back the needle out (make it richer) until you lose about 300 rpm off the peak.

Retest with the cowl on, if nothing has changed you're good to go.

If in flight you experience any sagging or power loss at full throttle, most visible on uplines, bring it down and richen it 1/8 turn. Don't fly an engine which is too lean, all the lubrication comes from the fuel and too little can damage the engine.
