Hello there!

Here's my just finished Widebody40 after its maiden flight. I'm using a Saito.72 with an APC 12x8, maybe I'll try a 13x6 next weekend.

I could only do 2 test flights because of low level fog, next week I'll write some kind of short review here. Anyway, the plane is really amazing! Right now I want it for pattern flying and not 3D, so I'll have to adjust the throws during the week, this thing is just so responsive.

El Widebody es muy hermoso. Lo me gusta mucho. Tambien, tu ingles es impeccable. Mucho mejor que mi espanol, y tambien es mejor que el ingles de alguienes quienes viven en los ustados unidos.

I have one about ready with the same motor.
Where did you put your C/G ?

Your plane looks great!

Thanks,

Felicidades por tu EPSILON, está precioso. AquÃ* en México estamos en pleno verano 44 grados centÃ*grados!

How is the vertical performance in your EPSILON with the ST 90?, i am planing in buying an EPSILON and instal a YS 110

SALUDOS

Gracias por tus comentarios, Ryan y Erdel.
Keep practicing your spanish Ryan, it's not that hard. (at least for me!)

Dave: I'dont remember the exact number in inches, but I got it around 35%MAC.

I have set up the plane for lower throws now, with shorter servo arms. I used the manual's "sport" throw suggestion as my 100% high rate and a 65% low rate. Both rates with some 45-55% expo. I hope it doesn't rain this saturday, we've had blue sky since monday!


Saludos!

Hola a todos!

I'm having very nice flights with my current setup, I moved the battery 6in. forward and it has made a very noticeable change! The plane is much smoother, it's has almost no coupling on knife edge and climbs and goes down very smoothly.
The APC 12x8 doesn't brake a lot on the downline, but it allows for a very smooth flight, without the torque of the 13x6. The 13x6 pulls more and would be better for 3d flight, anyway the 12x8 gives unlimited vertical!

For high rate, I settled on the "sport" settings of the manual. For smooth flying I'm using 50%low rate on aileron and elevator (with 55% expo) and 75%low rate on rudder with 70% expo.

It's a very good desing! I hope CAModel releases a wood fuselage 2m F3A plane, I'd buy one for sure.

Saludos,
Jean Paul

Buenos dÃ*as, nuevamente te felicito por tu avión, te voy a reomendar que si puedes y tienes la oportunidad en un futuro le cambies el motor por un YS. 63, creeme que vas a sentir la diferencia, yo ya he tenido los dos y te los digo por experiencia.

SALUDOS

J. Paul,

I ordered my Widebody 40 kit this week and hopefully it will be here before next weekend. I flew my first flights with a 4 stroke yesterday and liked the Saito .56 on a 5-6 pound plane. I was expecting less power.

How is the WB flying now with the .72? Are you happy with performance over a 2 stroke?

J.Paul Saure

Hello there Blwblw.
A friend has the Widebody with the Saito56 and an APC12x6. I've seen it a couple of times, it has good a vertical, not unlimited but it is a nice amount of power.
The 72 with the APC12x8 pulls noticeable more. Vertical is unlimited, loops big and round, and the plane feels very light.
After using the 72, I wouldn't consider a 2 stroke. I think a 46FX with a tuned pipe would be close, but with the standard muffler it is no way near. Maybe a strong 50 would make the deal.

I'm very happy with the plane and engine!!!

Saludos,
Jean Paul

Jean Paul,

Thank you for the info as I'm flying a new plane. Today was the second time with the Saito .56. The plane is a Sig Kavalier and it probably weighs about 5 pounds. The engine only had about 70 minutes of time on it when I flew the plane on Saturday. I was very surprised at the power of the .56. I was expecting a lot less. It has very good vertical and good top speed with a 12x6 prop. I'll use a 11x7 the next time I fly it as I'm cutting grass too much. The .56 is great engine.

I've been looking at the Saito .72 since the price of the .56 just jumped about $15 lately. The .72 isn't that much more in weight and not much more expensive, so it started looking like the right engine.

The Widebody 40 arrived today. I just opened the box and looked at all of the parts.

Jean Paul,

I ordered the Saito .91 for the WB 40. Should be here next week.

J.Paul Saure

WOW!!!
That should make for a wild ride!!!

I guess throttle control will be a major factor! After looking over the plans, I will probably do some reinforcing here and there for durability with triangle stock, and extra ply for the main gear. I'll definately use 2 battery packs and 2 switches. I saw a suggestion to double up the firewall, so I'll do that. Maybe a large fuel tank. 4-40 rods on everything. Heavy DuBro clevis and horns. The .91 will mean not worrying about weight.

By the way, my oldest son is named Jan Paul.

Why two batteries and switches? Its because of the big engine that I'd worry about weight.

philpop

good question????????????

Some people put in 2 batteries and switches since those are the main causes of crashes. Since the WB40 will be my best plane, I'll take the extra precaution. A couple of guys do this at my club on some planes.

The 91 is only a few ounces heavier than the 72. It has .5 more HP for the small weight increase. Jean Paul already has unlimited vertical with his 72, so the tradeoff with 3 more ounces to 1.7 HP vs 1.2 seems a good one.....unless I'm making some wrong conclusions here. The second switch will weigh nothing and I hope to use the second battery for CG adjusting instead of weights. I think I'll have enough room to move it around when shifting CG.

I'm open to any comments since this will be my first plane with this much overpowering and the 2 switch/battery installation. If the 91 will pull the plane with power to spare, then the extra weight would be good with winds.

J.Paul Saure

I thought your own thumbs were the main casuse of crashes.

Blwblw, I think you're doing some wrong conclussions here.

Be ware of vibration, the 72 already shakes a bit and the plane is light in construction. My opinion is that 2 switches and 2 batteries (and the 91) are overkill for a plane this size. Keep it light!! These planes fly so well because of their low weight (and their great design)

Keep in mind that you're not only adding 3 oz more of engine, also a heavier mount, heavier prop, more fuel and more wood to reinforce the fuse. Besides, the extra weight on the nose must be balanced on the rear, so that should make for near 6+ oz more of weight in total. Add the 4-40 rods and I'll bet you're near 7oz, that's about 200gr. The plane weights less than 2300gr so you are going to end near 2.5kg, that's 9% more weight. OK, the 91 should pull more than enough vor vertical performance, but I'll guarantee you'll loose some of the hot-knife-in-butter, crisp, light handling that this plane is soooo good at.

That's it.

Saludos a mi tocayo Jan.

I´m agree with you, i have .90 and it don´t need 2 switch and 2 bat.

agree es estar de acuerdo , cierto??? la carga alar se va a la cres....

Jean Paul,

Thanks for the comments as you know what you are talking about with the plane. So, I'll cut weight then. I'm not sure how large a prop it takes. I'll start with a 12x8...I think...whatever gives good pull as I'm not that interested in top speeds. Maybe 2-56 rods then. Glad you mentioned it before I started building. I was planning on a 10 oz tank, but I'll check fuel economy on the test stand first. I'm getting 10+ minutes on 8 oz with the Saito 56. I can live with a 10 minute limit. I'll use Dubro foam wheels and that saves weight. 4 Futaba S3151 servos and some lightweight servo for throttle. I need to ask somebody about the best little servo to get. Those save a good bit. A guy at the club has been using those for a while now.

We lost a couple of planes due to what had to be switch failures. I don't mind the extra switch if I knew how to do it without an extra battery pack.

Maybe I'll come close to the .72 weight if I'm careful. I'll save at least an ounce with the mini throttle servo and foam wheels. I'm not sure I can stop the order on the 91. It was delayed because of some other things I ordered that weren't in yet. I'll call tomorrow and see if the package shipped. If it is on the way, I'll have to build carefully. I'm not sure if the 91 is a long stroke engine or not. I think the 72 is a longer stroke 56, so you get more vibration from that. You mentioned a heavier mount. What mount did you use? The 91 is very close to the 72 size.

Did yours come out nose heavy?

Thanks for the advice.

If you are worried about switches try a JR gold switch. For the extra $5, you get two paths for the current, gold connectors, heavy duty leads and positive on-off lock. I have one in my WB 60 as well as all my other planes.
As for batteries, you may try a 6V pack. in addition to more performance from your servos, if one cell in the pack died the pack would likely still provide 4.8 volts since most ni-cads fail "open". My WB has a 6V 800 mah pack that powers 2-8231 servos, 1-4721 servo, and 1-8101 servo (Ail, Elev, and Rudd) for 5 solid flights per charge.

Brian,

I forgot about the 6v batteries. Good idea and the JR switch too. That sounds like the solution. I have a trainer with JR servos & switch with Futaba receiver and battery and everything is compatible.

Jean Paul,

I think the Saito decision was made for me in a way. I called this morning to change the order to the .72 and they were out of the .91 anyway. The .72 should mail out Monday, hopefully. Your comments about the plane losing its edge is what made me decide on the .72.
