Dumb question: With the DX7 and AR7000 can I mix the Aileron with Aux1? I'm using Aux2 with Elevator.

It isn't a mix per se. You turn on the flaperon function then set the control limits for each position of the flap switch. If you are using 2 channels for your ailerons you already have flaperons turned on, you now need to set values for each position of the flap switch.

Got it. All thats left is the throttle linkage and the throttle servo. Can't decide how to install the linkage.

Throttle linkage is done. went under the exhaust cut out and thru the angled back wall. Fuel tank and lines are installed. Since I moved the tank back toward CG I'm hoping the extra length in fuel line won't affect engine performance. It's an OS FS 91 w/ pump. I think it should be ok. For some reason when I install the stock spinner the plastic back plate warps when I tighten the Propeller nut. Making it difficult to screw on the cone. Finally all thats left is to mount the RX and battery - connect all the servo wires - and balance.

maynardrupp -  Did you happen to keep your extra, I am looking for wheel and gear pants.  I just picked up a used Extra and found out that flying the plane is great but not thrilled with the landing gear setup.  As I ripped it off the plane today - nothing too bad but a few hours of work ahead of me. 

So I am looking for wheel pants and gear pants also I am looking for any suggestions of improving the landing gear.  thanks all!

Love the plane and it has an OS 120 in it and boy doe it go striaght up!! 

Thanks for any suggestions or parts for sale!

I do have pants and a replacement 6061T6 landing gear but I may want to rebuild the plane. The wings are perfect. the fuse from the canopy back is fine. The firewall, and forward fuselage just seemed to fall completly apart at every glue joint. I deadsticked the plane in fine but tall grass. It didn't even break the prop or the landing gear. The fuselage is a mess though. Not an impossible rebuild but I never liked the way it flew. I had an OS 75AX engine on it.

I replaced that plastic thing with a good True-Turn spinner.

NRAD2000:

I just wanted to add a few things concerning your setup.
I had the same problem setting up my transmitter for dual servos on elevator. I use Hitec radio. I had problems getting both servos to work together without a Y harness. The solution for me was to use ELEVON settings. This made both elevators work together.

Also, I recommend making certain that Horizontal Stab is installed at Zero incidence with the wings. Test fly the model before any incidence change. My model originally flew nose heavy. I moved the tank back 2-4 inches,(A note of caution though; doing this too much may effect engine running. For my GMS 76 it is just fine) Since you are using a pump, moving the fuel tank back closer to CG is best.

Adjust Ailerons to perfect center, (Neutral) then turn the clevice 1/2 turn down. Both of these things made the model glide like it is on a rail. I usually only have to give left or right inputs to stear the plane durring dead stick.( The 1/2 turn down compensates for flexing upward durring flight.) If the ailerons are slightly up, it will be difficult to land as the nose will pitch up when the engine is throttled back to idle.

Land gear is sorry, it will bend very easily. I strongly recommend two things.
1. Epoxy (30 min) the landing gear block very well before flying, else it will easily break and repair will be inevitable. Mine broke on the first landing. (Since I epoxied it back together it has not broken, even with some very hard hits).

2. I bought DU-Bro tough gear. I have a friend with a bandsaw and he cut it down to an 1 1/2 width from 2 in. It has proven to be very tough. I have had some hard landing since i epoxied the landing gear block and used the Du-Bro tough gear, both of these things have worked well.

I hope these things help. Happy flying.

maynardrupp- thanks for the feedback, if you ever decide not to rebuild, your Phoenix let me know and Iwill be glad to pcik up the remaining pieces.

Iwill look into other landing gear options, but the stock landing gear does not hold up well at all!! time for 30 min epoxy and some landing gear modifications!

Nolefan thanks for the advice. I will look at the landing gear block and set up once more. Actually, where the blind nuts sit I did glaze that whole area with 30min epoxy - you think that is enough?

Bob, I never had any issues with the gear box, just that soft aluminum gear. I had a guy in toledo, and if you look back to last year's posts, or maybe 2008, You should find some threads about that and I gave the name of the guy in Toledo that made mine from 6061T-6 alum. That works just fine. I think it was about $40.00 though.

Maynardrupp

 Thanks I will see what I can find for your guy in Toledo

hi maynard ....

after reading your post i got to wondering what there is about your 330s flying that you do not like? I have one also, and it is a long ways from my favorite plane. mine will dump a wing unexpected at various times.

That's exactly what I don't like. It will also do an unscheduled snap roll while rolling over at the top of something like a loop.

the plane weighs 7.6lbs (bathroom scale) - wish I had a fish scale. It balances a few ounces nose heavy at 120mm (manual recommended). Fuel tank is close to CG. because of the tank the nylon wing bolts are a pain. I have to unmount the tank (release velcro) to access the nylon bolts. Maybe this weekend - if weather is nice I'll maiden the plane. hopefully its a fun plane to fly.

Have anyone used magnets to hold there canopy in place? I was thinking of using those Rare Earth magnets - probably 1/4" diameter and 1/10" thickness. I'm no physicist but would the Magnets interfere with the RX not receiving signals? I have been wanting to maiden flight my plane but it has been windy (very windy) for the past few days. It's that time of the year when all the leaves start falling.

Yes, I used magnets and they worked very well. Mine were 3/8"round and !/8" thick. I left the tabs on back of the canopy, just didn't use the screws. They worked flawlessly.

Flew mine with DLE 20 today,great combo,think 7.8 lbs.

where is everyone putting there remote glow plug adapter? I haven't figured out where would be a good place.

Good combo,Bad video! http://www.youtube.com/watch?v=t9tHkanr1Mw

NRAD2000:
After trimming my cowl so that it is just ~1/2" longer than the ears it bolts to (1/4-3/8" overlap with fuselage), I mounted my remote glow hookup just 3/8" behind the cowl line, in the on the RHS of the fuselage, middle of the white stripe. So it ends up maybe 3/4" behind the front of the firewall. Works and looks OK there. I chose RHS because there should be less oil there.....but there is no oil anywhere but the bottom now that I have the exhaust coming out the bottom.

I ended up getting a remote glow plug adapter (I use them on my Heli's) and placed it in that exhaust cut out on the bottom. I epoxied a small piece of additional 1/4 ply (one inch square) and mounted the adapter onto it. I think it's in a strange place but not visible unless someone really looks for it. I haven't had a chance to maiden the plane yet. Bad weather. I probably asked this question before but - what should I expect when I throttle up and go down the runway? Landing? this is my first aerobatic airplane. I have the throws set at the recommended LOW. I do have the throws set High on idle up.

Off on a Tangent: I had to cutt one of the elevator on my Seagull Decathlon. it's the CA hinge. what is the best way to re-hinge it? I was thinking of using a dremel rotary cut off saw and saw out the old CA hinge. Maybe start it with the Rotary saw and finish it with the Multi-tool. I don't have one of those hinge slot machine and I'm not sure how powerful they are to cut into old CA hinges. I did a test on a piece of balsa wood. the cut is just as big or maybe a hair thicker then the CA hinge. Its not a snug fit like when I first installed it but slides easily in. I added CA to the hinge and it Holds but not sure how strong. You guys think this is ok or you have any better ideas?

Put new hinges where the old ones aren't. Hinges can go anywhere along the hinge line. They're very easy to install new, so place new ones in unused hinge line into "new" wood.

Hello, I understand your apprehention. Maiden flight! You have set the plane up correctly. Balenced it at 120mm, I have the fuel tank 2-3 inches back, engine has been tuned. Gear block has been epoxied, Ailerons are neutral, everything is really tight. If test flying (without cowl); it flys needing about -12-15 up trim. With cowl on it trims out at -6. The cowl appearently adds lift to the nose. I would perhaps test it slightly nose heavy to prevent any unexpected surprises.After successful test flights balance it closer to level. ( Balance completely together and upside down.) Once satisfied all is ok and engine tuned correctly the plane should fly very well. It tracks very straight, If it is not very heavy, and trimed right, it will land very nicely. I some have complained that the nose pitches up with throttle at idle; I found that the cause of this is having the ailerons slightly reflexed (UP). Because the ailerons span the full length of the wing to the fuselodge (it is the area next to the fuse that effect this) the up ailerons next to the fuse act like up elevator and pushed the triling edge of the wing downward at engine idle. That is why I suggest making extra sure the ailerons are neutral and 1/2 turn down on the clevis to prevent this. This also enhances the glide performance if the engine quits. Mine glides like a trainer. Also, with the engine at idle durring landing it will tend to float like a trainer after flare. If it is 8lbs or less and balanced right it will land very slow. (mine is 8lbs). Other than this, enjoy flying it.

nolefan1961,

thanks for the info. the plane weighs 7.6lbs. OS FS 91 w/ pump. Ran the engine on a test stand - pointed it up and down at low and high throttle - so far so good. Everything is mounted including the cowl. Balanced at 115mm. it's a few ounces nose heavy. fuel tank is close to CG. All I'm now waiting for is the rain to go away. I'll have someone film the first flight. I'll check the ailerons one more time.
