I know what you mean about the chin scoop. Really too bad if it all has to go for the muffler. My Aerotech Yak and my Goldberg Monster both got cut totally out for muffler and they looked sooooo good with the scoop.. I guess we could buy a spare cowl and hang it from the ceiling and look at it once and a while

. Now I have five biplanes. This one is the coolest so far. Hope the D/A 50 will rock it pretty well. Anyone doing a smoke system. I have the sullivan system ready to install out of my Yak. The Yak went down the road because of the China Kote coming loose terribly at the seems after only ten flights. ARRRGGGGGH!
Equipment
(6) 8611a servos for ail/elev
(1) 8711 servo for rudder
(2) 5245 Hitech digital minis for throttle and choke
(4) TBM/Fromco 2800 Lion 2cell packs. 2 for Rx with a wolverine dual switch and one each for smoke and ign. with Jaico regulators (except smoke)
Sullivan smoke system
D/A 50 with Slimline smoke muffler
3" stand offs (2.5" if needed)
4" Skylites for grass field
I will use all their supplied hardware instead of buying hundreds of dollars of extra stuff and see how it works. I am scared of some of the junk hardware that comes with ARF's.

We should have our's going by the end of Jan. It will be E powered so no issues with the scoop

My wife and kids will be going out of town to her parents for Christmas and I will be staying home with three days to myself soooooooo..... I may get a good start on this plane. That had ought to be enough time to get most of it done. Since all holes are pre drilled for the control horns it doesn't leave much to error there. I don't want it to end up tail heavy. Hope there is enough nose moment to prevent that.

Surely SOMEONE has finished this plane and flown it by now. Heck, its been out almost a week! I'm going pull all the hardware from another plane to build this one, and I'm not ready to quit flying the other one yet, so its going to be a while for me.

Just a few pics of what I have encountered so far. Not much really but I do wonder why so many small hinges? Seven holes in all! I deleted two of the small hinges (one of which was badly drilled) and installed three large size hinges and left two of the smaller ones in between. Plenty of rudder throw!!!!! On to the horizontal stab. Looks like on the CD they call for 6 1/4" from firewall to back of back plate so the 2.5" stand offs will be the ones to use. I want to get the tail on tonight so I can start installing the engine and radio gear tomorrow. Should be fun once I get past the hinges. Did I mention that I HATE hinging. Gorilla glue or Epoxy. Doesn't matter to me. I still hate it. I used the Radio South Pro Hinges (large) on my Monster (GB ARF).

That is a very bad drill job for the rudder and I do not understand the small hinges on the rudder?

I always like to do my engine work before I install the stab, elevator and rudder, this way I can stand the fuse on end against my work bench to do the engine box work. I get the engine mounted, make sure it all fits and then take the engine off and do everything else. Not suggesting anyone do this but it works great for me.

I been using pacer hinge glue works great and you can clean it up with water so you can do a better job have it on some of my 35-38% planes no problem with the glue at all try it dries fast also.

denney47,
Yes, it is a bad drill job. Hope my elevators look better. I haven't glued the rudder on as of yet. There isn't any engine box work to do besides setting the laser cut engine bolt template on and drill. The cowl is pre mounted/drilled and the cowl will only need relieved for the cyl/muffler. Firewall is pinned already.
shundley, I have used the Pacer canopy glue and like it. There is just something about the hinging process. If it is pre drilled it is never good enough for me and If I do it myself I sweat it to get it just right. I thought this bird would be A1 in the hinge dept. but I don't care for the small hinges on everything. I would rather have three of the large hinges per elev. than six of those little ones. IMHO

I was just playing with the horizontal stab and with the bottom wing bolted on and the stab in place, the right stab is quite low (not parallel to the wing from the front or rear). Not only that, but the vertical to the horizontal is off also, but the other way. The left measurment is longer than the right measurment when measured from the rear top of the vertical to the aft corner of each stab tip (yes I have it centered properly). If I sand the right stab platform (bottom) to cure the vertical to horizontal problem then the other problem between the horizontal and the wing is even worse. I suppose I should just close my eyes and start gluing but I am starting to see a bad trend here. Anyone else verify if there is a out of square situation with the fuse to wing. If there is one doesn't dare correct it because everything has been pre assembled and nothing will lign up crooked or straight.

You may want to contact Aero-Works and see if they will replace it, I doubt if they will but it will not hurt to try. I had a very bad deal with them last month, they made an agreement with me and then would not follow through with it so you will probably not get any help but I would give them a chance.

I have been an aircraft mechanic for 17 years and an r/c builder/flyer for 20+ yrs so maybe I am being a little too critical but when I lay down $$$ for what is described as a QB ARF I want to just throw a bottle of glue in the box and shake it!

I would just like to have someone else verify that this is an isolated problem with my hinges and my stab not parallel to the lower wing. I know several of you have kits so bolt the bottom wing on and slide the horizontal stab into it's slot and see what you find. Check your hinge lines and make sure you have all thousand hinges in line with center.

Thanks,
Kent

I'm a big fan of the QB series planes... for a plane that goes together over a weekend, they've always flown as well as any wood ARF at the field. With that said... you made me a little nervous reading about your elevator/rudder alignment.

So, I went down to the basement, dug it out of the box, stuck the stab and tail surfaces on, mounted the lower wing, and started measuring. After maybe 30 seconds of alignment, it seems just fine. When the wingtip to stab measurements are equal, the elevators are positioned with equal spacing to the rudder. The rudder-to-stab measurement is equal on both sides. I should be able to glue this up without any sanding. Looks like mine will work out fine. The rudder/elevator hinges (all thousand of them) seem to be in proper alignment also, the surfaces hinge to full deflection without any bind. From just a visual perspective, the stab seems perfectly parallel to the lower wing.

I guess time will tell how broad any alignment problems are, but if yours is that far out of whack, you should give AW a call to discuss.

With biplanes, I'm always more concerned about the differences in incidence between the upper and lower wings. I'm not going to build this plane for a while, so I won't know if there is any, but with the way they set up the angle brackets, any minor twists should be easy to manage with washers or spacers.

Mark - if you're reading these... are the wing incidences supposed to be identical on the top and bottom wings? Sometimes there is a little "up" built into the upper wing. I'd hate to adjust that out if its supposed to be there.
