Im not sure when it comes to all the thrust calculations, but a 46AX will definitely be good enough to pull this plane around. With the 55AX on the OMP Edge 540 Im getting about 11750 RPMs with the Xoar 13x4 but this engine hasnt been fully broken in, Ive got less than half a gallon through it. And if I remember right my 46AX wasnt fully broken in until at least two gallons were through it. With a APC 12.25x3.75 on the 46 AX I was getting around 12000 RPM's. A good 3D foamy is another good inexpensive alternative to learn 3D, but only downfall its harder to practice hovering or any 3D if the wind is more than 5 mph since they are soo light. And the micro servos just dont seem to perform as good, could just be the cheap ones I bought. I also forgot to mention, after thinking about it I remembered I have that aileron servo out of my pro yak, so its actually 4.5 lbs plus the weight of a standard hitec servo(1.5 oz).

Essentially an electric costs as much as the pro yak when you add everything up. Im just thinking what will i be able to get more time with with the weather turning. But you are right about the wind - I guess the 2nd part would be the cold...so either way. I think I need to move to a warmer state so I can fly year round.

A very cheap but capable setup would be the DW foamies, 38" plane of your choice for $39. If you get everything else from hobby city you could have a bind n fly plane for less than $150. I got my brushless outrunner motor for $10 that would be good for that 38"plane. I got 2 1000 Ma 3S battery packs for $5.95 each. I also got 5 10x3.8 props for .99 each. The brushless ECS I got was $15.38. And the Spektrum 6 channel parkflyer reciever I got from them was only $43, regular $49.99. Shipping was about $12. I got my extensions from towerhobbies, but that was about $20. Thats a grand total of $156. For a bind n fly 3D capable plane. If you have never bought stuff from Hobby City you should check it out, you will be amazed at the prices escpecially for Lipo batteries, brushless motors, and ECS's. If you compare to the rimfire and electrifly brand, you pay 3 times more for name brand. And 99% of the time those name brands are manufactured in China, only difference between the two is a fancy sticker. I did forget to mention the 4 servos I got from Hobby city for 2.99 each, compare that to an equivalent Futaba with close to same specs at $13.99 each.

Like you said...wind...dont think the foamy would serve me well during the off season. But ive seen hobby city. Ive been on their site trying to find an equivalent for a brushless 480 size motor . But I know scrap about electrics.

Im in the same boat, Im learning this electric stuff too.

I got a couple flights in today with the Pro Yak and Saito 82 combo. This plane is a blast to fly, Im getting used to the difference in the power curve between the 55AX and Saito 82. It takes some time to get used to, the sound from the Saito is soo much more quiet compared to the 55AX that sometimes I think Im not giving enough throttle to hover but the plane is hovering anyway. Also torque roll compared to the 55 is almost non-existent. I could be hovering for 5 seconds no aileron input needed at all then I might get a slight torque roll, but its nothing compared to the 55. I had a little trouble with the battery, somehow it came loose inside the wing and made its way towards the wing tip, luckily I had a safety clip connecting the two wires together. I noticed whenever I got into a hover I the plane kept wanting to lean towards the left wing and I needed a lot of rudder to correct this. Sure enough when I got the plane and picked it up I could hear the battery moving around inside the wing.

Hey beach...whens you're little spotter gonna start doing rolling harriers?

I have the OMP Edge with a 46 it needs a OS55 or a Webra 50 to really come alive, also have a kit built Mojo 60 (yes the wings come off) with a Saito 91 mounted tons of fun and easy to 3D a 100 would just be more iceing on an already fine cake.
Also a Primo with a Magnum 52 mounted. That engine is going to be replaced with an OS 55 so have not really been able to wring this plane out but I can say it is very very durable. Lots of low altitude arrivals from the Magnum going rich in the midrange and sagging/gurgling at just the wrong time.
Electric is also an option look here http://kalteisen.com/ I have several of Q's balsa planes
yet to order a new foam design but my kids are going to get me one for Christmas just need to order it.
or this http://www.valuehobby.com/product_de...d=4&item_id=45
Go with the recomended setup and you will have a kick a## little 3D plane that will keep up as your skills develop.
I fly the Sabre a lot, in fact lots of times I bring a Glow ship to fly that never gets out of the car.
I might convert the Edge to electric as a test bed next season if time and funds permit.

Beach - if you're good at not nicking props....give Xoar a shot. Tried another one today on my showtime....Xoar pulle hard!!! Since they are lighter than the APCs they will spool up FAST too!

Thats what I use, Xoar 13x4 on the 55AX and Xoar 14x4 on the Saito 82. I like them alot, like you said spool up is instant, and less torque roll since props are lighter. Also if anyone is looking to get a Saito 82 for $229, they are back in stock on horizonhobby, just checked.

I too found the 12x4 Xoar better on my OS50FSR; I had been using a 12.25x3.75 APC, and the thrust seemed about the same, but the throttle response/spool up was waaay quicker with the Xoar. Switched to a Saito 82 on the same airframe (GP Reactor), and tried a 14x6 Xoar, but found I liked the 14x4 or 15x4 APC better on the 4 stroke. LHS didn't have a 14x4 Xoar; might have to give that one a try.

Its crazy how the lighter wood prop affects torque roll so much, with the 46AX and APC 12.25 x 3.75 I would be constantly fighting the torque roll just to keep the canopy facing me, now with the Saito 82 and Xoar 14x4, it just hovers with barely any aileron correction needed. I could definitely seeing myself getting into trouble now, this past weekend I was thinking to myself the next step is to do a tail touch on the ground. Ill make sure to get it on vid for you ro347, then you can get a profile and start having heart racing fun. It dont get really fun until you are on the edge.

You're right about the torque roll. Like i said before, yesterday was the first time I was actually able to take off with a Xoar intact...well I popped the showtime into a hover - and it was so much easier than with the APC. Didnt have to fight it.

Nothing against APC of course. Wish the Xoars were as durable!

I know what you mean about durability, earlier this year I wanted to switch from a APC 16x6 to a Vess(wood) 15x8on my Aeroworks Edge 540. Well, the turns out the plane was alittle nose heavy and as I was taxing to takeoff, it tipped over nose first and broke the prop. I paid about $20 with shipping for that prop.[:@]

Exactly what happened with my first Xoar.

you're swinging a 16x6 on the edge? what engine?

Saito 125 with a bunch of mods to acommodate the larger engine. Throttle servo moved back to where the rudder servo goes, rudder servo moved back to the tail opposite the elevator servo. Balsa tray added behind wing bolts to mount battery further back. It flys hands off inverted without adding any weight to balance. I think Im at 3.75 in back for CG. Right now I have a 16x4 APC on it, I need to switch back to the 16x6 wood prop. My dry weight is 7.3 lbs.

WOW...a 125...that thing is a monster!!!

I like to think so.
