Hey guys,

While the Strega situation is awaiting resolution, I have decided to begin work on my Legacy kit.

I have a Fox Falcon .59/.60(??) that I want to use to power it. Does this engine choice may any kind of sense?
Pros/cons??

Thanks,
Jim

Jim,

I'm not familiar with the Fox Falcon engine, but I've seen a few Fox .59 powered stunters. They seemed well powered for the designs they were being used with.

I personally believe that if the weight is carefully watched, the Legacy could be powered with an OS .46LA.

Perhaps the ideal thing to try would be to use a mounting system that would allow you to easily change engines anf allow you to try several as the chances allow.

Hi guys,
The famous Legacy Plane, I scratch build one and I'm using a Super Tigre 51 that Mr. Bowman rebuild for me. The plane does great with this set up. The other Legacy is a ARF and I'm using a RoJett 61, Brett Version and she also does a great job. So which one is the best??? I believe if ya have the plane and engine set up it'll work just fine with the set up ya have?? Both planes fly very well and yes if I had to choose I would go with the RoJett but my little ST does a great job?

The truth of the matter is that the scratch build Legacy weighs an ounce more than the ARF??? At the moment I couldn't really tell ya which one is the best??? I love the sound of the pipe but the ST runs in more of a two cycle sound?? I made a few changes to my scratch build and it wasn't enough to change the way each one flys. I didn't even have to change handle setting from one plane to the other??? I think the SV 11 flys a little better than the Legacy, just me okay??? The Stiletto flys better than all of them??? I believe John is correct the LA 46 will fly the legacy?? (The ST takes six ounces to fly the pattern, the RoJett takes six and a half ounces to fly the pattern?

)

I'm not a Fox expert, but John Hall is. He told me that the iron piston ones were the best, tho I would be very afraid of the vibration. The Falcon was the last version of the .59, and it was called a .60, but I wouldn't know if it had more displacement or not. I would speculate that it was the same. Duke did some weird stuff. The .19 and .201 were both .19's, with the only difference being what was stamped on the case. In that case, for A/B FF gassie class changes, but in the case of the Falcon .60, probably just for ad copy and sales to the R/C blokes.

How about a Magnum .52 or the older .53? Real good power for weight, .46 sized case. My GMA .53 powered Magnum Plus was clocked at 3.7 sec. laps on 64' eye to eye .018's...that takes a LOT of horsepower. Tank was rattling around in the nose. Didn't bother my ST G.51, but the Magnum didn't like it at all.

Cons: Heavy, not really a stunt engine, wouldn't be my choice. Pros: paid for. Consider an Evo 60 - 46 sized case, 60 power, tuned for torque and a 4/2 break, affordable.

OK, let me throw this is the pot . . .

How about a Saito 62? That's what's going in my Legacy when it's done.

Anyone care to say ya or na??

Brian

PS to Gary; you gonna have either Legacy at the field Sunday?

Hi Brian,
I plan on having both planes, not sure which one flys the best?

I couldn't believe that the little Tigre did so well with the plane??? But her through the whole pattern, everything seemed trimmed well so off to the pattern she went??? This one even has a engine cowl?

I flew each plane on the same lines??? The Saito will be a great set up for that plane, just be sure to build the engine around the plane?? At the moment I'm very happy with my little Tigre 51, Mr. Frank Bowman rebuild.

(Hope to see ya at the field??)

A Legacy with a Saito 62 won Advanced at Brodaks this past summer

A Randy Smith ST 51 or a Enya 61 would be nice, I believe.

Jim Oliver · « **Reply #9 on:** November 26, 2011, 07:08:42 AM »

Old thread....anyway, I decided on a PA 61/pipe set-up.

I don't care how old the thread is,remove it and put in Saito 62.

Sorry I couldn't resist.

Hi guys,
Allen is probably correct but if you want a plane that doesn't have a muffler hanging outside. I would spend the money and get yourself a RoJett 61 Brett Version, cause if ya do buy this set up you won't be sorry. The engine leaves a nice smoke trail and has a great sound and yes its a lot of money buy not out of reach. Just save a few pennies and get the set up. Also the OS 40 VF or OS 46 VF is a great set up and it will do the trick for ya. (Check with Randy Smith, I believe he has a lot of items for these engines.) The saito is a nice choice but its seems most four strokes leave a lot of oil in the engine compartment??? What ever ya decide it will work with this great plane. I would rather have to much power?

Gary

If he is going to check with Randy Smith, he may as well get a PA from Randy. Also, excess oil in engine compartment, is cured with a peice of fuel line on the crank case nipple to route the oil out of the plane.

Brian,

I recently finished a Legacy and it does well with a Saito 56.

PS: Are you Mike's (Cottage Grove, OR) brother ?

Hi John,
I don't believe Randy has anymore PA Engines?? I know he has said he has plenty of parts for the OS Engine. You're correct the PA would be a better choice but not available??? Thanks for your input.

Yep; I'm his MUCH younger brother. So the 56 pulls the legacy around OK? What's the final weight of the Legacy with the 56 installed?

Brian

REX1945 · « **Reply #20 on:** November 29, 2011, 11:17:42 AM »

Brian,

The model weighs 60 Oz with the Saito installed.

I cut 1" off the nose and installed a 4 Oz tank; getting about 7 min flights with 3.5 Oz.

I've been getting 5.1 sec laps on 65 ft lines with a Zinger 13-7.

I've gone to wooden props to reduce both nose weight as well as reducing the flywheel effect of APC's, which are quite heavy.

Good to hear from you.

dirty dan · « **Reply #21 on:** November 29, 2011, 02:10:23 PM »

While APC props in general are relatively heavy it is worth noting where the weight actually resides. At the hub. The blades are actually plenty light even if not as light as those on a good CF prop.

Folks rejecting APCs due to "flywheel effect" may be making a mistake, especially when the alternative is Zinger props.

60oz . . . ummm, sounds good. I'm targeting a final weight of "around" 60 oz. I think the 62 should pull that just fine. Of course I'll need the plane up and flying to try different props. I do like the wood props, and found the Xoar props very much to my liking. They are well finished and the balance is very close out of the bag. After trying 6 or 7 different props on my OS LA 46 powered Trophy Trainer (52 oz) the engine told me that it was happiest with the Zoar 11/5. I'm getting very sweet runs with consistancy with this combo. Every once in awhile someone tells me to "try this" . . . "try that" . . . try try try. OK, so I do, get poor runs or speed etc. and go right back to the Xoar 11/5. As soon as I reinstall the Xoar, the engine is "happy" again.

Brian

REX1945 · « **Reply #23 on:** November 29, 2011, 04:57:13 PM »

Brian & Dan,

   I sure like the XOAR props as well and intend to try more. They are good quality and very efficient.

   My first attempt with an XOAR was a 13-8, which pulled the plane around w...aaa..a too fast (4.65 sec).
Possibly an XOAR 13-7 or 13-6 would work well if the RPM'S aren't too high. No local source I know of.

   I have tried a Top Flite 13-8 super-M, but it was way out of balance and vibrates a lot with the plane
flying a lot slower than I like.

   The Zinger was a "shot in the dark", since it was the only prop within range at the LHS in Auburn when I
went in there. It loads down the engine a lot more than an APC 13-7 and gives the airspeed that I like.
I'm sure I'm paying for it in the overheads, though.

What is the venturi diameter (or are you planning on the RC carb) ?

I have two Saito 62s and they are both the C/L version. I sent the carbs to Bob Reeves (he referred to them as "carbs") and he is doing his magic on them. I hear he really knows how to make the C/L versions perform.
