RE: Sig Rascal 110
My Syssa on the business end of my Rascal is swinging a VESS 18.5 X5.5 and will hover my rascal pretty good. Great little engine and great big plane.

RE: Sig Rascal 110
A year or two back there was a fellow running a DA-50 on his Rascal. He said he was using it for a glider tug and needed the power. That big engine looked way out of place to me, but then they gotta do what they gotta do!

RE: Sig Rascal 110
I got the tach reading last time out,(november) and just checked my tach and the battery is shot so I would'nt bet the numbers are correct. It's an old analog tach and is usually fairly accurate I might post again in spring after a warm up and a new 9v battery. But the rest of the post is right on....Take care and have fun in the snow...Jim

im looking for a rascal 110, i have a new in the box,unopend GP Revolver 70 i would like to trade for plus cash if anyone has one..
|
is my 20 cc rngine bi enough for this bird. its Pretty !
|
It will fly it around, but a 26 is the standard size in gas power for the Rascal.
|
I just "discovered the Rascal 110 yesterday & now I have to have one.
I'm looking for a home for my Saito FA180 on steroids. It's based on a case that is milled .035" & the compression ratio is upped to 12.8:1. The intake manifold is ported for 12mm FA220 "Big Bore" carburetor. Running CDI spark @ 35° BTDC W/15% Cool Power it makes just a bit less than 3 1/2 HP. (18 X 8 @ 8450 RPM) That ought to make for some interesting aerobatics yet be light enough to float around. SIG is expecting a shipment in April so I need to get some $$$ squirreled away. I was going to do another Sr Telemaster, but this bird looks like it’s a lot more capable & just as easy to fly. My trainer was a Sr Telemaster W/a Saito Fa150 that I later converted to CDI. |
April huh? Well, I hope you don't loose your head of steam by then, as the 110 is one awesome flying bird. Mine has plenty power on an OS 1.60 twin. Your Saito 1.80 should really rip.

Don't worry, I won't loose my steam. I've been looking for something for that engine (I have 2) for some time. It makes the same power as the FA220 glow & uses less fuel than an FA150 glow. |
Your Saito Fa180 will do the Rascal good. I run an 18 x 8 at about 7450 RPM which is on the minimum side for power . The extra 1000 RPM will do you good. Although the Rascal is not made to do hard aerobatics it's still a very good flyer. Easy take off and landing. Very smooth in flight. With it's big wing it doesn't like any high wind. I have had mine for about 7 years now and still enjoy flying it.

I have a DLE 20 RA in mine, not yet flown

I'm looking not so much for hard" aerobatics as big loops, Cuban 8s, reverse Cuban 8s, torque rolls, stall turns, knife edge, flat turns, etc. I found these videos. http://www.youtube.com/watch?v=mv70ld3yiMI Thr Rascal starts @ 2:53 http://www.youtube.com/watch?v=8dX8AIhaGDg |
So, are you working the Saito's over yourself? I have a 1.80 that I don't use much because it likes to kick the prop loose. Would your mods help my engine? Do you work on other peoples engines, like mine?

On any Saito about 100 or above, CDI will soon pay for itself in fuel savings. Fuel economy improves by about 25% when the same glow fuel is employed with CDI. Max RPM usually improves by 200-300 RPM. On my FA200Ti fuel economy improved by 70% but I didn’t see an improvement in HP. My prototype FA180HC was made from an FA150 case that has a .055” shorter deck. I had to use a .020” spacer to keep the piston crown/head clearance acceptable so a net reduction in compression height of about .035 is maximum. The FA150 case also required a lot of clearance work that will not be necessary W/a 180 case. On an FA180 case the proper compression height can either be accomplished by milling the case deck .035” W/the stock FA180 piston, or use an FG57 or FG84 piston & reduce the deck by .020”. (The FG57 & FG84 pistons have .016” taller compression height.) Just using the FG57/FG84 piston W/CDI would make a significant improvement bringing CR up to about 11:1 & it wouldn’t require valve notch clearance work or deck machining. Here is a thread about the FA180HC prototype.http://www.rcgroups.com/forums/showthread.php?t=1754616 Here is another thread that documents HP & fuel consumption. http://www.rcgroups.com/forums/showthread.php?t=1769449 Finally here is a video clip of the FA180HC CDI engine before I ported the intake manifold & employed the 12mm FA220 Big Bore carburetor. (The induction improvements added 400 RPM @ WOT) http://www.youtube.com/watch?v=5xaiAR8Yelc As you can see in the video, CDI makes a huge improvement in idle, hand starting & transition as well as the HP & fuel economy gains. If you would like me to work on your engine RM me for a phone # & we could discuss it. A CH-Ignitions CDI will run a $150 installed & tuned. Depending on which way you want to go, either 11:1 or up to 13:1, the engine work would run from $75 to $125 respectively plus shipping/insurance. That would include a new piston & ring. If I use your piston & reduce the deck .035", the 13:1 combo would be $90. |

This is the type of flight envelope I want except maybe a bit more power for vertical. http://www.rcuvideos.com/video/Erics-Rascal-mov |
Just picked one of these up, and it looks like I have a few questions. Mine is missing the dihedral brace ,and is it supposed to be aluminum or wood? I imagine both will work safely... Also what are the odds someone has a spare left wing strut ? now that I think of it they MIGHT work on either side? never stopped to check that yet..
Thanks for any info... I can always make a strut but it never hurts to ask ! |
The struts are airfoiled, so there is a right and left side, but they can be installed backwards.
The joiner is aluminum. I think I'd give Sig a call. You might be able to get the parts you need for a price that makes trying to build your own not worth while. |

here's mine with a dle 40 twin. will do torque rolls.http://www.rcuniverse.com/forum/atta...mentid=2038707 Also flys upside down.
|
Neat. How did that turn out, balance wise?
Possible to put some sort of pipes on the engine and install the cowl? |
Well I got my missing parts built, electric power in the plane ..and it flies like a million bucks.
Such a sweetheart... |

I didn't change anything to balance it. I had a magnum 1.80 on it and replaced with the 40cc engine. The battery and ignition went back into the nose where the battery was before. Balances i n same place. As far as the cowl I trimmed the bottom off, put a piece of balsa sticking out from the firewall at the top to support it and made a bikini cowl.

why are the pics upside down SloPoke ?

Good Question. I don't know how to rotate them.
