I wouldn't expect that, but I would expect it to fly the plane better, at least that has been my experience between APC and MA.

OK SR, you convinced me, the DA 100 will go on it. Put a 3 blade prop to mimic an LT3 powered Cessna, and It will be INSANE!!!!

It will probably turn less RPM but make more thrust.

And allow you to make a more impressive crater when you yard dart it! ;-)

I "yard darted" my Sr Telemaster with the CDI Saito FA-150 on the nose @ WOT. There was only 2 other guys at the field that day & they were putzing around with a Piper Cherokee twin W/small glow engines when I did it. The wind was quartering across the runway & since there was nobody else in the air I was flying a slant pattern.

The Sr Telamaster had been through a few minor mishaps & every time I made repairs I reduced the dihedral, reduced the wing incidence to 0-0, made wing struts etc. It was somewhat aerobatic capable especially since it had "ample" power. I was doing "spit "S"s & as I was pulling through inverted with the elevator on a going away orientation, I realize that I had "insufficient altitude" as it went. vertical (down) When it speared the fuselage into the moist spring Southern Indiana clay, the 1300 square inch, 95" span wing disintegrated into large chunks of confetti.

What pi$$ed me off about the whole thing was that NOBODY BUT ME SAW IT! I've seen numerous voideos of R/C crashes, but NONE as spectacular as that one!

As I approached the carnage, the fuse was stuck almost vertically form the earth & the engine was buried with only about 1/2 of the old style "fire hose nozzle" muffler sticking up out of the soft clay. Of course the first thing I did was grasp the muffler & pull the engine from the soil. It was soooo "heavy" that I had to release my grasp immediately!

I had flown the plane for a couple of seasons so I had no regrets other than the lack of video or even witnesses. I didn't need any tools to salvage the servos engine, etc. There wasn't a piece of the wing left that wouldn't have fit into an envelope. I placed the wreckage in the trash barrel & went home.

Correct, with a Tru-Turn 2.5" spinner it turns the APC at 8,550 and runs super smooth, idle is still 1,650. I may get to the Xoar 16x6 tomorrow. I set the valve lash using the thinner of the two OS feeler gauges.

We need to make some thrust measurements. I don't have the resources now to build a test bed. Any one else rising to the task, or is there another source of thrust data? Thanks.

Does it count that it flattens the soy beans which are 20' away.

Wow your Soy is still green! It has all just about turned brown here. Corn is fading fast too.


I have so many planes now that I am thinking, do I really need a 14' WS plane in my fleet? I still have two full kits sitting on a shelf, B-25 and P-61, both are huge WS planes. Trouble is, I never have enough time to fly them all.

So, how well does the Rascal fly and what can it do and what bad habits can it have? It's a $900 kit, and would hate to waste that kind of money on a plane that would berly be flown if its a PITA to assemble and doesn't do much other than putt around the sky. I have planes that already do that.

Hi Dave, looks like FARCC, Having lost planes both in the "Cornfield of the Children", and in (under) the soybean plants, at FARCC field, I think corn is better. It took less time, three days from the corn vs two weeks in the beans, to find my planes. Also, the bean plants like to grab your legs and trip you up. Only problem with the corn (other than the "children") was that the lost plane was green and yellow, same as the corn stalks that time of year.

Vbr, Richard

I hate having to research and answer my own postings, but has anyone waded through this site lately?

A cotton field has to be the worst place to louse a plane

Dan- I respect your vast wealth of knowledge about many things, but this time you have fallen for some folk lore my friend.

There is no reliable or repeatable rule of thumb. It just ain't so no matter how many guys at the field have said it for however many decades.

Static testing only tells you how well it is flying that stationary bench it's sitting on. Nothing more. It cannot be a predictor of any flight mode, except possibly hovering, because it isn't moving through the air. You are missing half the information you need.

I'll dig out the books and find correct formula that most people use and post something later today or tomorrow.

Dave, they generally seem to have a bit more pull and accelerate quicker. A MA seems to fly like I'm tuned too rich. A little sluggish.

Psst, Dave has an impressive collection of props. Some of our perceptions come from how we fly. I'm not a pattern competitor but I like to fly pattern stuff and expect good vertical performance out of my planes. So, my way of flying shows up good/poor performance more than guys who enjoy just flying around, flying on the wing, and doing touch and go's. Let's hope Dave uses the right APC so he sees how well they perform.

I might receive an APC 15x8 today or tomorrow, I can only hope it is as balanced and and has the hole centered as well as the 16x6. Two of my previous APC's had the hole at an angle and others were difficult to balance. We need w8ye to make some appearances and keep us all straight.

Well that's the point. wiith "ample power" it won't just "putt around in the sky".

I posted a DIRECT LINK TO YOUTUBE so you can watch in full screen mode.

As far as being a PITA to assemble? The Rascal 110 doesn't take .long to assemble. Certainly no longer than any other high wing aircraft with wing struts. I don't see why the 168 would be much more difficult.

Personally, I think they should has done a 12" version and that would have been perfect for the FG-61T

Dave- I put a sanding drum on my Dremel and sand a small square spot on the backside of the heavy blade. Doesn't hurt it structurally and easy to make small adjustments.

HERE'S A POST about using a DA-100 on a Rascal 168.

The discussion about appropriate power for aerobatics STARTS ON POST # 44.

Sr Telemaster 150.
I have done similar things to my planes with the same result. But the best crash i ever had was when an old guy at are field had put all his planes away and was just watching me fly and he got distracted when I crashed and he turned to look to see that I had crashed and asked what happened to Capt. Crunch somebody said he crashed the old boy said what I missed it, dog nab it got in his car and left.
I dont know whether to feel good that somebody waited around for me to crash or the fact that I crash enough that people wait around to see it.
And with the advent of video no one caught any of the five airplanes I crashed at sig this year on video.

OH that was YOU!!!!!!! Those were spectacular! Then there was the mid air between the Clipped cub and a foamy. Surprised he got that big plane down with half the wing ballooned.

Still, the best crash was the Something Extra stuck straight up at the edge of the runway. Cheetohs did a number that day!

i see you have been trying to figure out how big of a engine to put in the 168.
Have you decided or still figuring. I plan to order one in the next couple weeks and I'm trying to decide too. But i have time to ponder

General consensus on FG forum is that a 70cc would be adequate for flying around, but the craft needs a 100cc powerplant. for aerobatics.
