flyinhigh025

Hey all! I am currently starting a new project. I am attempting my first gas to electric conversion using a Lanier Stinger 10 as my subject. I was wondering if anyone out there has had any luck with this project? What motor/battery combinations were used? How about all up weight? Any suggestions on reducing weight from the original airframe? Thanks for all your help. (It looks like I will first use my Himax 2025-4200 motor/1320 3s Lipoly)

Okay, I might be one of the first to tackle this subject. If anyone is interested in my results of this experimental project, here it is. I equipped the Stinger 10 with 3 naro bb servos, a magnum 2000mah 3S Lipo, and a Himax 2025-4200. The airplane has plenty of power for our mile high altitude here in CO, and will fly fast for it's size. A good sport type of model. I spent some time removing foam and other materials from the original kit, and adding carbon fiber. Thus I feel the airframe is much lighter then it was intended to be. So, I have a fun airplane for sport flying like I said, but mine has some nasty slow speed flying characteristics. Don't get even moderately slow and crank in the up elevator, it will snap and spin in a heart beat. Not a 3D airplane by any means, but still fun.

If anyone experiments with a similar project, let me know how it goes!

I have converted two stinger 10s. One was converted from a nitro to electric. The other was built from the kit for electric. I use Hitec hs55 feather servors for the tail feathers mounted in the side of the fuselage within four inches from the horns. This is a weight saving set up. I use a Hitec hs 81 servo in the wing for the ailerons. I mount the servos with foam insulation that comes in a can. It's called "Great Stuff" This fills the rear of the fuselage and holds the servos well but adds very little weight. You don't even need mounting screws. Use thin piano wire "z" bent linkage straight to horns on each aileron instead of the typical heavy bent aileron control linkage. Skip the abs turtle deck. Cover the top with iron on film instead. Skip the abs front turtle deck and make a battery hatch cover. The plane now looks like a "Mini Ultra Stick" The "old" wing is still a little heavy for electric flight. I built the new wing very light. thinner balsa vaneer. 5 inch diameter cut outs in the foam, etc. The gas convert flies ok. The scratch built Stinger just for for electric flies great. I use a Himax 2816 on one and an E flight park 480 on the other. Lots of power. Center of gravity requires building out the front of the fuselage about 1.5 inches.

Do you guys know the correct COG for the Stinger 10? Working on a conversion and have no documentation. Thanks!

I am in the process of building one of these and have been thinking about converting it from glo to electric. I have been flying glo for quite a few years but just recently pought a Parkzone p-51 and really like it. But like I said I am new to electric's and am clueless about electric motors, and am not sure what would be a good motor for this plane. I have seen electric motors labeled 10 or 15 size I think like glo engines, and also by other numbers. The motor in my p-51 is a brushless 480 outrunner and don't really know what that would compare to as far as a comparable glo engine. Why do they label the electric motors different ways, and what do you think would be a good one for this plane? I would like it to be fast.

I have an Eflite Power-10 in mine because it appears strong enough and I had an extra one laying around. [&:]
My plane is ready to go, but I have not yet maidened it. It came in at 37.6 oz AUW with a 2200 mAh 3-cell which results in about 20 oz /sq*ft wing loading.

Eflite makes a [link=http://www.e-fliterc.com/Products/Default.aspx?ProdID=EFLM4015A]Power 15 Motor[/link] which should do the job if you want more speed.

I purchased MotoCalc to help estimate the performance of a plane with a given motor, prop, battery combination. Web-o-Calc is a similar program that is freely available online.

I would be curious to hear how it flies after you have flown it, and thanks for the info.

OK...I know it's been a while since this was originally posted...but...

I found a Stinger 10 on eBay and couldn't pass it up.

This winter I built it for electric from the start. (see "My Hanger" for the specs) Built basically per the plans, with obvious exceptions.

COG is aprox 2 & 3/8th inches from leading edge

Up weigh is 2lbs. 4 oz.

Love this plane, great flying characteristics, both fast and slow.
