BIG non-scale Airplanes

I'm not familiar with the QB 60 Monster, although I'm sure I have seen it many times. It just doesn't ring a bell.

The method to eliminating most aileron problems is to use a servo connected to the surface via a simple direct pushrod. No torque rods and no bellcranks. Of course, this means that the servo will have to be mounted out in the wing and that provisions for cabling will have to be made. This is so easy and simple to do it is pathetic. Yet, many of us still struggle with habits long familiar.

It appears that lots of the old standard large glow models are disappearing along with their enthusiasts. It would be nice to see some of them resurrected in modern materials and construction techniques. We certainly are not lacking for powerful engines these days.

Seemsd like Bridi had some. I'm not sure if the guy that took over will have them too. search for bridi mk

Take a look at the old Lazy Ace, it is a classic.

I'm afraid about the only way to resurrect these are scratch building from plans. I like the stuff of the '60s (now vintage R/C).

(OT on small but old) Nice thing about electrics is the power is up with new batteries and brushless motors. I've been looking at some late '30s Scientifics like the Varsity at 50" span. It is light enough it could be powered electrically, mount batteries as brick and as forward as possible to balance short coupled nose.

Have a look at this site. It is a flying school and he sells plans for their trainer. I have one and it flies great. carries cameras, drops parachutists etc. Yes it is all stick construction, but worth the effort.

Just pulled up a 3-view of it. Elliptical fuselage cross-section, tapered wing, tapered lifting stab, now that's a building job! Has a neat look to it, though.

I've recently found myself banging my head against the too-light electric motor problem. I built an HOB Chea-Pass Laser Stick 10 and converted it to electric. The kit was designed for a .074-0.10, and I figured that since a .10 can put out about 20 oz of static thrust, then an electric motor that puts out 20 oz should be just about right. Ahh, look, my little Esskay 400XT should be perfect.

Now, an AP .09, Enya .09, or OS .10FP all weigh about 6 oz by the time you include the mount. A nice .15, which is what I think everyone puts on that plane, weighs more like 7 to 8 oz with mount. So, when I put my stubby 1.8 oz electric motor on the nose . . .

Oh, sure, I crammed the battery to the very front, but it turns out that the battery weighs about the same a tank with fuel in it. The receiver and ESC are crammed forward, too, but the rx + ESC weigh about what the throttle servo would weigh . . . I tried lightening the tail, but I still wound up bolting two tire weights (3.5 oz total) to the front of the firewall, just under the motor. Yes, the balance weights weigh about 20% of the takeoff weight, or twice as much as the motor itself. How embarrassing . . .

About a year ago I scratch-built a Commando (Modelcraft, 1942, I think) and it came out beautiful, but even after I replaced the motor with a larger one and put an ounce of lead in the nose, it's still a little tailheavy. And the wing isn't rigid enough, but that's another story.

I built several years ago two Greatplanes SuperSporters, size 20 and size 40, and they was the best flying and more funny airplanes of all my hangar. I buyed also the fantastic 90-120 size with a OS FS91 four stroke. I had no time yet to build it but I think it is an excellent choice, maybe not in production now by Greatplanes.

Greetings,

I just finished building a T-Rex by Mosquitobite planes at

It's an 85" wingspan laser cut kit. I converted it to electric and it flies extremely well. It's pretty overpowered with an Axi 4130-20 and 9s2p 5000mah Tanic pack lipoy's. It uses some very unusual construction techniques and is a very precision laser cut model. Highly recommend it.

How about a Dallaire Sportster? Now that's really going back :^) To about

1936.

It's a real floater and needs lots of runway to land.

The Dallaire's nice, but give me a Cumulus - same era (1937, I think), a little smaller at 96", and great lines.

I thought the Ace Bingo line went extinct back in about 1997 where are they available from? please...

FWIW the Sig four star series fly very much like a Bingo, but the Bingo just Looks better ;-)

hi bob

actually they were discontinued in the mid 80s.I found mine when i di a wanted post in rc universe and other rc sites.You can find them o e-bay but got to be patient.in e-bay do a search on ace.

Hmmm, that's earlier than I thought. Since I don't "e-bay" and don't frequent any of the online forums, I guess I'll just have to be content with the NIB Big Bingo that I have stashed in my "to-do" area.

Sig was advertising a big bipe ARF in the latest MA.

I'll have to kill a few of my current planes so I have room for the new ones ;-) I have a nice old Quadra 35 for the Big Bingo. I also have a nice Brison 4.2 waiting to get a ride on a GP Giant Aeromaster if I ever get the time to crack the plastic wrap on the box and start building.

You shouldn't have said that! I said that a couple of weeks ago and guess what? :( mk

My favorite planes get a hard life, but tend to get repaired fairly quickly even after major damage. One of them is all new from the trailing edge of the wing forward. now it is slated for a new wing since I managed to get the wing to "clap hands" last week. the problem is that I seem to have a collection of "hanger queens" that take up a lot of space, and rarely see daylight
