Bought the electric arf and scrapped the motor for a proper compression ignition engine.

OK Bob, I'll bite.

Whatcha gonna stick in the nose?

PAW 55 or something larger?

AMB

OK group bought a VMAR Nouvo 51 inch span from Richmond RC to replace the mini tele with the OS 10 davis

head that I gave to my wifes son, Its a high wing tail dragger 4 channel a little beef to the fire wall
and it will most likely get the LA10 with the Davis head should get it via big brown on Friday site pix looks good and only $60 martin

Hi RR,Dan and AMB, I didn't know there was a Rascal iteration still in existence, I checked, and the Sig ARF is almost the same size as the original Goldberg Rascal 27 Free Flight kits I had in the 1950's. You occasional find the original kits on ebay for ridiculous prices. they were all sheet pre-fab models similar to Comet Struct o Speeds and were guaranteed to fly by Goldberg models! I started with one and it flew so well, I soon bought another. It climbed in a fast spiral and flipped out into an opposite turn glide like a Pylon FF model. They were both powered by Cox Pee Wee's(.020) and I would start both engines and release them simultaneously. They always landed within seconds of each other. I don't know how Sig's ARF is constructed, so I can't begin to recommend appropriate power for it. The Goldberg kit called for .02 for FF and .049 for CL. I'd guess that the Goldberg model weighed about 3.5-4 ozs ready to fly with a Cox Pee Wee installed. These were true Sport FF kits and didn't even come with a DT. Have a good time with yours, RR;

Hi Guys, I just found a pic of Golbergs Rascal 18, which is a rubber powered prefab that looks and was built just like the Rasca 27 FF kit, except the Goldberg Rascal had a 27" span. Here's the link:

I think the Rascal might have predated the Rascal 27;

This is the little electric arf with a 30" or so wingspan.
I have the schlosser .5 rc pegged for it and think I can substitute the engine, fuel tank, 250 rx battery and 3 micro servos for the geared 180 motor, esc, 7 cell 300 pack and the called out 2- HS-50 servos and come out ahead.[8D]

The PAW .55 would be another good engine for this bird - both would be a bit to much but then again that is what the throttle is for.

It has only marginally more wing area than the Little Lancer flying quite well on the schlosser .25.

Out To Launch!
Lil' Rascal Electric ARF

Got a minute? Then let's go fly! SIG's new Lil' Rascal Electric ARF takes park flying to a whole new ballpark. With a super small 29-3/4" wing and 180 geared electric motor, the Lil' Rascal Electric is the perfect friend to take along when you have just a minute or two to squeeze in your favorite pastime.

Lunchtime, coffee break, early morning fly time. All suddenly have become opportunities to take wing and soar. The Lil' Rascal Electric ARF builds fast; in as little as 2-3 hours from box to field. With a one-piece pre-assembled wing, factory installed motor/gearbox and a low parts count, you'll be amazed at how such a great model can go together so fast. The Lil' Rascal Electric ARF is no toy airplane however. The light, tough all balsa/plywood construction is completely hand assembled, then covered with genuine Aerokote® covering material in that classic Rascal motif. Standard micro radio electronics are needed, as is a 7 cell, 300mAh NiMH battery pack.

Sig's Lil' Rascal Electric is available in two color choices


Flying the Lil' Rascal Electric ARF is uncommonly great for airplanes of this size. Fly it in typical small areas, even in relatively high winds. Full aerobatic maneuvers are possible with typical rudder/elevator movements. Plus, she's extremely stable and easy to fly. In fact, you'll probably run out of lunchtime before the Lil' Rascal Electric ARF comes back to earth. Run times of ten minutes or longer are typical with good throttle management. Specifications
Wingspan: 29.75 in 756 mm
Wing Area: 134 in² 8.7 dm²
Length: 20.5 in 521 mm
Flying Weight: 8.5 - 9.5 oz 240 - 270 g
Radio Required: 3 Channel, Micro receiver,
2 Micro Servos, 5 A ESC

Ran up the engine as installed today.
Almost ready for maiden - but not to happen this weekend - other commitments.

Rob,
Would this be good with my PB 0.33?
With all the other activities, I haven't yet got to scratch-build.
Could be a start for me.

Hello Peter,

I'm sure your engine would fly it very well. Of course I would have the 6x4 prop on it. As the plane is not much of a floater you might want a larger remote tank so you can "motor around" a bit.

With a 1 ounce tank and heavy stopper, tailwheel, and 3ch I finished out at 8.4ozs and electric is recomended from 8.5-9.5 ozs.

Last time I ran a tach on my pb .033 it was very new and not run in yet, but got 10,000 on the pb 6x4 and using apc constants this calcs to .4lb thrust and pitch speed almost 40mph so if you choose components wisely, forgo the supersize tank and tailwheel just use a 1/3-1/2 oz tank you might hit 8ozs. So while not quite a 1-1 thrust to weight certainly would provide a spirited flight.

Bob looks super what engie is that??? martin

Martin, It looks like a Schlosser .5cc R/C , as mentioned a few posts up.

Several years ago I found .pdf files somewhere on the internet for the Rascal 18 and the similar Ranger 21. Both are simple sheet models with box fuselage. The Rascal 18 has the cute ellipsoidal wingtips and stab/fin curves I love to laminate while the Ranger 21 has the more modern squared off tips and stab/fin. The plans are intended for use to print the pieces on 1/32" balsa with the correct colors and markings!

The plans were drawn by somebody named Paul Bradley and have construction notes in addition to the outlines of the parts. I could e-mail the .pdf files (each is under 500Kb) since Mr. Bradley seems to have offered them free to any good home. Scaled up in Adobe Acrobat the outlines could be used as the basis for a larger version.

Dan Vincent

Bob, That Rascal is a very sweet-looking design.

I liked it from the first time I saw a sig ad.

Looks like you set the balance and it can't help but fly.

I really envy you for owning those lovely little Schlosser diesels.

Lil Diesel,
I would be interested in the drawings - I'll send you a pm - Thanks.

Dan, I was agonizing using this plane for the schlosser - just thought the engine needed an airframe a bit more exotic, but seems like it will be a decent fit. Just have to get over the ARF stigma.....[:'(]
I tried to fly it on Sunday to dismay.
Went to an electric field and it started on the 3rd finger flip, and I idled it down and asked around if it was to loud? everyone was amused enough to want to see it fly. I walked out to the field and chucked it w/ full throttle and she rose up nose high and snapped. I think the engine torque and 6x4 prop was to much for this airframe at full throttle.
I had a couple of minor repairs and on Sunday will do some power test glides over the soft pickelweed at the gas field and if that confirms cg will try a partial throttle launch over the pickelweed.

What kind of RPM are you turning that the torque would be an issue? I bet the electric setup with the gearbox puts more torque to the prop.

peterburford

Rob,
I'm watching the thread from afar.
I have a 'plane (Blue too) on the way.
Hope that the diesel fuel doesn't peel the covering.

Peter I would guess that if the seams were sealed with some thinned epoxy and an artists small brush no issue and easier than using ca glue martin
little or big any fuel can with time get under them

Peter,
Just make sure to seal the first two bays back internally.
On the Lancer I took epoxy and thinned it with alcohol to get it to seal the wood better and lighter using three coats.
On this Rascal I just used 2 coats of non thinned epoxy on the engine bay only. I noticed I had some fuel leak back to the second bay the fuel tank bay - so yes the Lil Rascal gets oily.
So far the Sig Aerocoat seems to hold up to the fuel well.

Greg, Good point, I think it is spinning around 12k on the 6x4 - I don't think the supplied 180 geared 2.6:1 motor on 7 cell can match that? I did take out the down thrust which may account for the balooning and the cg is listed as "at the main spar" which gives 1/4" leeway. Can't imagine the cg being infront of the spar?

I guess at 12,000 RPM the Schlosser tops the original motor. That's actually very powerful. It makes 40W of power at 4.5 oz-in. That's twice the power of the supplied motor. The original setup puts about 2.6 oz-in to the prop. That thing should be a blast!
