Howdy Rascal Fans!

I recently acquired a new Sig Rascal 110 (Red). The only ones that I have seen up close and in the air have had a Saito 180 on the nose. This engine does a great job on the plane...plenty of power...but I am really interested in putting a gas engine on mine. I am aiming toward a G26, but the problem is that I am having trouble locating a tread on RCU or someone who has some advise (pictures, alternatives, etc...) on mounting the G26 on this airplane. All suggestions are welcome, and appreciated. This forum is also open to all who want to show off their rascal. Feel free to share your opinions, photos, advice, and stories.

Thanks Rascal Fans

I think you'd find balancing the plane with a G-26 difficult unless you added weight to the tail, and why make it heavier than you need? I can think of a couple of smaller (lighter) gas engines with better power-to-weight ratios, the RCS 140 and the Roto 25. Both are roughly the same displacement, half the weight, more power, and also more expensive ($400 dollar range w/muffler). Plus, the G-26 is fairly wide, relative to the width of the Rascal, because of the side carb and side exhaust, and the firewall might not be up to the task without some reinforcement. The RCS and Roto engines are rear carb, and can be obtained with side or rear exhaust. A gas Rascal is a neat idea, though. I've got a 40 size, and if the 110 flies anything like it, would be a blast to fly with that kind of power.

I like the scheme!!! I have researched some on the Roto 25, and read some positive reviews on this engine in another thread.

Thanks for the input!

Hi

Check this link - I used a MVVS 26cc gas motor - no more glow motors (maybe small ones )after this - really enjoy it.

The G26 has lived in my Rascal 110 for 1.5 years now. It took a bit of work. Custom mount, aluminum muffler standoff and I put in a 32 oz tank. It will fly for an hour that way. My on-board GPS acumulated 1,500 miles of surface distance covered. Some of it autonomous. it was 20 pounds with all the gear and camera's. I had some structural issues but they were easy to fix. This plane is designed to be lightweight and it's structure dictates it. If you make it heavy, fly it gently. The nice thing about the g-26 is maximum reliability with no Electronic ignition. I like a magneto engine. I have enough stuff on board as it is without having to have an extra battery pack just for spark. I also mounted both elevator and rudder servo in the rear. There is a cutout on each side of the fuselage under the stab for that. I didn't pull/pull from the center. By the time it was all said and done, I was a little tail heavy. I finally built a new twin tail boom plane so my rascal is in retirement. I won't fly it with all the gear anymore so am looking forward to flying it just for fun. The fire wall has been just fine. It's built in pretty well. My trouble came in the butt joined tail section, and pulling a strut mount right out through the sheeting under a wing when pulling out of a screaming dive. It brought about 25 percent of the sheeting with it. Fortunately I got it set down without the wing folding. I openned up the sheeting on top of the wings over the struts and beefed them up. (They just had a little ply block set in place with hot glue on the sheeting in there. No false ribs around it or anything.) I don't fly with the wheel pants or stock tires. I have some Du-bro inflatable 5 inchers up there for tactical take offs. Even with all that, it's a floater.

Have fun. It can and has been done to quite the success.

MVVS 26 IFS/RC (3094i)

Capacity: 25.66 cc / 1.60 cu. in.

I'am from the UK,I have the red version 110 fitted with MVVS petrol engine and stock muffler.Although Ive fitted the plane out,I havent yet run the engine.All up weight is 13.5lbs.Its a very nice model and seems well made,like all Sig planes Ive had,mainly the 40 version of the 110. TIM...did you use the supplied engine mount?,if so, how is it standing up to the MVVS...looking at the photos it seems as though you did. Thanks..Hugh

Hugh

I decided to use the supplied mount and it has been fine and I dont think that there will be any long term problems.

I later made a small air scoop on the exhaust side so that the bolt does not rub on the cowl - I discovered that the small scoop made a big difference to the temperature on that side of the cowl so I made another for the other side - actually I also like the look of them. The motor ran fine without them but the extra cooling must be a good thing.
I will take some pics of the cowl tonight and post them.

Just in case you run the motor on the plane without the wings - Dont be alarmed about it shaking, when you put the wings on it makes a huge difference.


Hugh - how does the muffler fit ?

I've got a Rascal 110 here for a university project. We ended up with a 2-stroke glow (OS 1.60 FX). We bought a beefier motor mount specifically designed for the larger engine size, but other than that everything is stock and went together by the book. We've run the engine, but haven't flown yet. We are aiming to maiden early next week weather/schedule permitting. It's a *really* nice airplane. I've been very impressed with the quality of the SIG ARFs (Rascal and Kadet) compared to some of the other arf's I've assembled. I have some pictures and notes from my project here. There's nothing too spectacular there yet, but I always like an excuse to look at airplane pictures ... :-)

Thanks Tim...thats good to hear as they fit just right for that engine,Using the standard muffler.I neatly cut a square opening in the side of the cowl,looks okay to me,hope its quiet enough when under power? Have not yet decided about the choke arrangement,may have to use a bell crank arrangement on a servo,but if its only needed a little when starting Ill rig some manual device!! Hugh

Hi

These are the scoops I added to my cowl - they are pieces of a pvc ruler - heated and formed around a dowel , cut diagonally and sanded.

Hugh

Because the carb is exposed in this setup I removed the choke and choke it with my thumb before starting.

There are at least four 110 Rascals at our club - with glow 2&4 Stroke and gas.

My buddy had his fuel tank split at the seam at the bung hole - probably just bad luck but worth giving a once over.

I am sure you/Hugh will enjoy the Rascal !!!

Thanks Tim...Helpful as usual...Hugh

Hugh,

Could you please let me know where you bought your Rascal 110. The large Sig kits are not generally available in the UK such as the 4 Star 120 etc.

Thanks
Ron

Well I thought I would write back and keep this discussion alive. Just an update, I recently acquired a Roto 25 gas engine for this Big Rascal. I have not run the engine yet, but from just the looks of it, the craftsmanship is simply amazing. Now that I have the engine, I need some serious advice from all you experts out there. I am trying to figure out as to where I am going to mount the ignition & ignition battery as well as how to run the spark plug wire through the fire wall. Any and all ideas are welcome! The thought of still using a G-26 is still my preferred option, but I have run into the problem of 1.)Muffler 2.)Backplate 3.)Mounting. I was thinking of using a B&B Header for the exhaust. Please if there are any more pictures, fell free to post them. Thanks again to you all.

Sorry ronaldh...Only just noticed your enquiry about the 110,(I look at so many sites I lose track) At the time of purchase many months ago,I contacted Kavan in germany and they sent it via Sussex Model Centre.Had to pay a fair amount of postage at the time. But since then Skylark models in tne UK have now got them in stock,at less than I paid.
I have in the past weeks finally got around to running -in the Mvvs petrol engine,and rigging out the 110 and doing a few ground runs etc. Not flown it yet,but Iam sure it will be a nice flyer.
The engine is a treat to run,and starts easily,ticks over at about 2000rpm.
Best of luck if you decide to get one...sorry again about the late reply,dont know how I missed it!!! Hugh
