I have a plane called a "NotForSale". I have had it for about 10 years and used to fly it as a float plane. I'm putting the landing gear back on it was was thinking about doing an electric conversion since I need to buy a new engine anyway for it. Had a .46 glow in it and it was very powerful for that sized plane. I'm looking to convert this to electric so I can fly 1 or 2 flights at the club field before work w/o having to deal w/ the setup and cleanup of a glow engine.
Any suggestions for motor, speed controller, prop and anything else I need for the conversion as well as where to buy? I'm a newb to electrics so simple is best for me.
My expectations are to be able to do sport flying with it and not necessarily the other stuff I used to do with it (hovering take off, hovering in place etc)
I have 2 11.1V 20C lipos (2100mAh and 1800mAh) for my electric helicopter I can use that have deans connectors on them.

Ditchit you are such a Brit! Not4Sale ... I had one 40 sized one of glow and now I got the 60 sized! Its a pretty light plane, if well built (you can expect an AUW of no more than 4.25 lbs) and may fly ok only on 3S, 4S would be better. But you can try a 3S set up with something like an AXI2826/10, something of that kind with perhaps a 13x6. I flew my Kyosho AgWagon on the AXI 2826/12 on a 14x7 and she will fly scale for sure, the AgWagon is not the ARF but a kit and was built light. As for ESC get a 60A one, its more versatile.
Do you want branded or average? You can shop at Hobbycity ... the Turnigy are ok for the price, esp when you want to do only sport flying.
Here is my Not4Sale 60 ... I hope to get her up one of these days. She's been sitting in the hobby room for like almost 3 years now! I think she will be running on 5S if I get her up, maybe with my Plettenberg Orbit 25-18 or the AXI 4120/18. Scaled up the wings are pretty thick. Its a 2 piece wing by the way.

Thx for the reply. I just flew it this morning w/ an OS .46 AX. I was breaking in the engine and I needed something I could throw the engine in. The NotforSale would fly great on even an OS .32. It has great lift on those fat wings so I don't think I need as much power as I have now if I go electric. I'm not looking to break the bank on my engine, ESC or battery. I'd like to keep the cost down to a "bang for the buck" approach. The NotforSale is nice because I can fit it in my car and it does not have removable wings to pulling it in and out is fast so I can get a couple flights in the morning done. I'd like to just do some nice and easy sport flying with it without having to pull in and out fuel or clean it up. One thing I found w/ Glow is that I should have mounted the engine on it's side so the exhaust came out the bottom right side. Right now, it runs along the top and gets the right aileron server oily. I had to put a cover over the front of it to keep the oil off the servo but it still makes it messy.

Oh man ... I am dyslexic ... you are David, I thought you were DITCHIT a UK guy ... hehehehe ... yeah the Not4Sale will fly on a .32 for sure. Try something from HobbyCity, if not then the DualSky motors at 2DogRC ... the 60A esc is great as it does not need a UBEC for 4S or more ... it will power the RX safely. If you want the DualSky then try this motor from it ... XM3564-5 ... that is the minimum for a start.

I had an email conversation w/ the guy at 2dogrc. Good feedback and ordered a setup from him. I"ll report back once I get it in and I"m able to test it. I have a good current probe from work I can use to test out the current draw for the different props I have to try out.

Here is what I ordered from 2dogrc.com: This was sized to use a 14.8V lipo 1 x Xmotor 4250CA-6T 900W (.46 size) (XM4250CA-6T) = $67.99 1 x Dualsky 60A/80A Brushless Motor ESC (XC6018BA) = $69.95
I yanked out the nitro engine and mounted the motor onto the firewall using the included mount from the motor. I added some metal spacers that I had at work to pull the motor about 3/4" away from the firewall. The Dualsky ESC came w/ a power switch that fit right into where my old one was. My landing gear is too short to use anything larger than a 12" prop so I used an 11-8 I had lying around. w/ the 11.1 Lipo it was running 7200RPMs. I flew it this morning on 2 flights. The 11.1V lipo leaves it under powered. I got about 6-7 minutes of flight time flying mostly at half throttle. The last flight, I was using the 1800mAh pack and overestimated my remaining time and did not have enough power to make the field. Good news is it's all grassy weeds on the edges of the runway.
Enough power to take off and fly rather flat, but not enough vertical. I'll need to order the recommended 14.8V 4000mAh Lipo now that I have everything running.

dditch ... how many amps are you pulling? I am sure she can fly on 3S but not unlimited verticals. You may wanna try a 12x8 ... check the amps you are pulling then see how it performs. I know that the 4260 on 5S is nuts for a 40 sized low wing so the 4250 on 3S is just about ok for sport flying on your Not4Sale but of course 4S will be totally fun.

I measured about 25 amps. I put a 14" prop (14x6?) and it was about 30amps.
2 days ago I got a 13x6.5 electric APC and it seems to like that pretty well. I get some decent vertical. I'm only getting about 6 minutes of flying time if I manage my power though. It's not the power I'm used to for that plane but I"m flying 2 flights before work each day this week so I"ve accomplished what I wanted to do as far as get in, fly, get out and go to work. It's lighter than I though. I need to weigh it on a digital scale to find out. It floats in and flies REALLY slow. Takes off in about 10 feet or less.

Only 30As? Hmmmmm ... wait till you go 4S ... you will love it even more. The only thing I find weird about the Not4Sale is that the elevator is sluggish at lower speeds, I guess its because the H stab is in the same plane as the wings, hence, the inner part of the ailerons are cut away. Enjoy her!

Measured the RPMS and Amps on the 13x6.5 APCe. It was 24 amps and 7400RPMs.
I still have the 11.1V 2100mAhr Lipo in it and still getting about 7 minutes of flying while managing the throttle. It really likes that prop it seems as far as efficiency goes.
Once I get the 4s pack, it should really rip!
BTW, I have mine set up for flaperons on a switch. I have not used w/ flaperons turned on it yet since I pulled it out but I recall using it back when I flew it more like a fun fly. Really low speed landings and short take offs (especially when I had it on floats). Flaperons do require you use one aileron servo on a different channel and turn on the mixing though. It would loop on a dime! Somone had sold me their electric Extra 330L (by Sapac). Just flew it this morning. Not nearly as good of a flyer as the Not for Sale but for $50, I could not say no. I think some people had some reviews on this plane, I may just post my impressions on it here on the forum.

My Ebay/Hong Kong "Tmetric" 5000mAh 14.8V 25C pack came in yesterday. This thing is a brick! Way bigger than I expected. But the Not4Sale is already light. Put it in and I'm getting 8600RPM w/ the 13x6.5e at 46amps at full throttle. Full throttle is only needed when I want some vertical so I can really dial it back in normal flight. It did not float in as easy as when I had the 11.1V 2100mAh Pack but I flew it like a pattern plane. Unlimited power and vertical! I flew it one time this morning before work. I flew for 11 minutes and was getting tired so I landed it. 8400RPMS at the end of the flight so I'm anxious to run the discharge program on my charger to see how much is left on it. I think I have more than enough power in this setup to put this into a 40 sized trainer if needed. I'm loving the morning flights before taking the kids to camp. I'm in and out really quick w/ little setup. Time will tell how this Hong Kong purchased battery lasts. Charging a 5000mAH 14.8V Lipo just seems scary! That's alot of energy compacted in a small space.

David ... 5,000 mAh packs? Wow ... that is huge for a 40 sized plane, but its ok, I do the same too! Used it for my WM SkyRaider Mach II conversion. Hahahahahaaa ... I am sure you can easily get more than 15 mins flight on one pack on the Not4Sale.
