I poured Gorilla Glue into the firewall and landing gear mounting area after they came loose. No problems since.

Was short.
YS .91AC & Slimline Pitts muffler. Stock fuel tank on the CG. Shifted the throttle servo to the rear end of the radio compartment. Five coreless FMA servos used - three in the tail, with the metal-geared one on the rudder. Sullivan tailwheel instead of the stock assembly. 2-56 CF pushrods and Rocket City ball links on all surfaces.
My kit made its long trip and arrived with no damage to the wing. The covering was a bit wrinkly in places, but nothing that a blast from the trusty heat couldn't fix.
Stayed up all night Saturday finishing it. Hit the sack & caught some Z's @ 7AM, then to the field forthwith.
Fueled up, fired up. The engine ran *pefectly* on my usual YS mix of 30% nitro 20% oil.
Wups! Spoilerons are reversed - up is down, down is up. Shut down, pulled the wing off, swapped the aileron servo connectors, reinstalled the wing.
Fired up and took off.

Total flight time? 9 seconds.
***?
Oh.
Reversed ailerons.
(With a 10X and flaperons you have to make sure that (A) the L and R aileron servos are plugged into the correct rx port, and (B) that they are wiggling in the appropriate direction.
The new kit is on order.

there are two kind of rc pilot
1) rc pilot who already took of with a reversed flight controls
2) rc pilot who still have to take off with a reversed flight controls
with modern radio, this kind of funy joke can hapen to everibody since it's now "normal" to reprogram the flight controls throw, expo and so on between two flights at the field...

darn that's a pity...but I do have a question (for ll those hat have done the same...)...how is it that one can take off without checking the direction of the throws a) when you're installing the radio b) if you alter the programming and c) before each and every flight..??? ESPECIALLY on a first......i mean its basic....basic R/C....like taking off without tuning the engine...
seriously i don't understand this one recurring problem...i can with aft cg, wind, and what have you.......but this...? sorry no.

it will hapen one day.... thrust me
I am a very very careful modeler. I build planes since 20 years
and it hapened to me also last year . Reversed ailerons on a maiden flight....
this hapened to me because I had to solve some minor flight controls troubles and I simply reversed one of my aileron servo.
In real live, I fly a wide body, we are 3 in the cockpit and I may tell you that somethime we all 3 simply "forget" to check some very important parameters, simply because we are too relax and too confident....
We are humans

20 years..ok i'll accept that ...but i see it happening far far too often...I mean it appears by some of the posts that many just revv 'er up and take off...no preflight check...
i've been in rc for over 20 years myself and so far so good....

I originally noticed that the ailerons were reversed while programming the radio the night before (@ 6AM, after pulling an all-nighter to finish the bird.) I originally reversed the ailerons in the radio, but then noticed that my landing mix (UP spoiler) was reversed as well. This means that I had the ailerons swapped at the receiver.
It was late and I was tired - I just didn't want to disassemble the plane at that point - so I decided to do it before flying.
(that was the Exhaustion bit.)
I then switched the ailerons back to normal in the radio so as to restore the spoiler mix.
(that was the Stupid bit.)
Off to the field.
One of the guys from work that has been 'threatening' to come watch showed up. We got to talking - office stuff, R/C stuff, etc. I excused mysely, fueled up and fired up. Did a quick power-on range test. O! The ailerons are still reversed. I shut down the engine, pulled the wing off and swapped the aileron servo leads
BUT!
I neglected to check the radio programming or checked the direction that the ailerons were going in. Talking with my mates and the physical act of swapping the leads allowed me to mentally check-off the 'aileron box.'
(that was the Distracted bit.)
Took off. Rolled like mad... first one way, then the other. By the time I'd gotten it upright it was heading for the street, and traffic. I decided to cut the throttle and put it down rather than nail someone and cause an accident... then the chainlink fence grabbed it.
So. What have we learned from this little missive?
1. some of us don't function all that well on two hours of sleep.
2. have one of your flying mates look over your new plane before you take it up. A fresh set of eyes can see things that you can't, or won't.
3. its late, and I'm tired, so I'll just end this here

wasn't my intention to get on your case if it came across that way...and goes to show that sometimes we must force ourselves not to overdo things and wait....2 hours sleep and ANY activity don't mix....
and yes..I do agree always have a friend look things over...if you see the same problem/mistake long enouh your mind will eventually cancel it out....then s... happens

No offense taken.
Besides. Writing about the crash is cheaper than a therapy session!
There's a bright side to this litle tale. One of my flying mates took the wrecked plane and is rebuilding it. He says that he has most of the fuselage done, and is working on the wing. (Its a straight-chord wing, so one rib is all that's needed as a template) I just gave him the untouched (!) cowl, canopy and control horns yesterday - once my new kit gets here I'm going to give him the fuel tank and landing gear, as my original ones are already assembled & plumbed and are undamaged.
I hope he pulls this one off!

ZG77,
When you get that sucker mounted to something, could you please post some tach readings? I know it's better than my Saito 100, but I need to see how much better, so I can justify the purcase of one. I have a sinking felling that I will be able to justify it(which isn't a bad thing, except for my wallet!). Please let us know. You are in Jersey, so I am guessing you are at 500 feet or less above sea level, which should put you on par with Cincinnati.
Thanks ahead of time!

Hey All; I got mine used so can not comment on the quality or lack of it. But I can say that this is one real fine and very FUN flying plane. I have been flyin FF , pattern/ IMAC, and 3D / sport planes for many years and I think this sweet machine is almost a perfect combo of em all !! It has a stock OS 91 FX with reg muffler on 15 % S&W fuel and an APC 15x4 prop. It flys so gentle and easy it could be a trainer and yet turns on a dime and will do most manuvers with ease and it will hover all day with no effort at all. I found out that sustained rudder drags are easy with this plane - I am really having a blast with it !! The only thing it will not do well is harrier - but I have not played with the CG or any spoilirons yet so ?? Overall I would highly recommend this plane - it is such a JOY and a BLAST !! Just had to give my 2 cents !Take care and keep having FUN !!!!! Rod in PA.
