Score ARF engine?
« on: May 29, 2016, 05:22:03 PM »
What would be a good engine in a Top Flite Score? What are the thoughts on a Score, good airplane bad airplane?

Lots of engines starting with the 46LA and getting bigger.  If you have the bux for a Stalker or a RoJett that might do.  One of the piped 40 stunt engines, if you don't mind the pipe hanging down or the rework involved in making a pipe tunnel.

Cut it open and verify the integrity of the control system before you fly it.

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

I do have a LA46 laying around. I've read the 46 isn't powerful enough for it, I saw the ST G51 was recommended. However I don't have one. I might get Tom Morris controls for it. I saw somewhere that the landing gear wasn't very strong too.

Have you ever had one Tim?

   Do a search of the forum and you will find many threads on the Score. It's had as much written on the subject as the Nobler ARF I think. I have one with many, many flights on it that has a Saito.56 in it with Morris controls and fuselage mounted landing gear. I have detailed the mods in several threads. The whole nose needs to be dealt with in the manor of scraping out the hot melt glue it was built with and coating all the joints with thinned epoxy. A few short comings but a good flying model. Mine is heavy at 70 some odd ounces but the engine and wing haul the freight well. I would use anything less than the ST.51, and would suggest that or something bigger, even if you don't own anything like that. The airplane is no longer manufactured, so parts aren't available. If  you don't have the ARF kit already or have an eye on a complete kit, I would just move on and look at something else.

'K.  Let me tell you a little story.  No, I don't have a Score, but:

One day last summer, at one of the contests in Auburn Washington, there were a pair of airplanes with signs on them that said "Free to a good home" in Paul Walker's handwriting.  The newer one got scarfed up before I had a chance at it, but I did manage to wedge Paul's 1988 World's plane, the "Atlantis" into my car and take it home.

It originally had a piped 40VF in it (well, judging from the date and the signs, it originally had more than one engine in it).  I kind of dithered around on what to put in it, but Paul said that a 46LA would be a good fit.  If it was anyone else I would have thought them nuts, but this is the Pacific Northwest, and he is Paul, so I said "yessir" and put in a 46LA.

It flies great.  700 square inches, 64 ounces, and with an APC 11.5 x 4 cut down to 11.25, it flies great.  It does a four-stroke in level flight at around 10000 RPM, has a soft break to a two-stroke going up and over, and it flies better than anything I've ever had.

So -- if the plane comes in at 64 ounces or less, certainly.  70 ounces, maybe not -- but you can always try, and change motors later.

My flying buddy has (had?) a Score with an ST 51 in it.  We could never get it sorted, and it always seemed to only have almost enough power to get the job done.

But: neither of us are ST 51 experts, so maybe there was oodles of potential there that we just didn't know how to tap.

I do have a Score (two in fact) and agree it is a fine-flying model. As noted above there has been a ton written about the Score on here, do a search. It is a modern design, with Ted Fancher's excellent Imitation airfoil (no doubt pirated from Ted w/o his okey-dokey) and modern 4.5 to 1 stab/elev AR and modern moment arms. I gutted mine and totally replaced the control system with Tom Morris BC and pushrods. Throw the stock controls in nearest recycling bin. I built it totally take-apart including dismounting the stab/elev and adding a metal plate to tie the front of the wing to the forward fuselage, and other mods.

As much as I love the LA46 I think it would be marginal in a Score. I flew mine (it is retired now just cause have a newer plane) with a ST51 improved by Tom Lay. It is MORE than enough power and I had no problem getting it sorted, with help from more experienced friends. I later solved all possible "power" questions by putting in an Enya 61 (new style).

I would not hesitate at all to put the time into a Score to make it work. If you want one and can't find one, my #2 Score is never-built and has the covering stripped off, ready for polyspan and dope in place of monokote. It could be had for a song. Too few years left, too many projects.
