View Full Version : Just Finished Great Planes Cub 40
12-14-2006, 02:20 AM
This is my first kit build in over twenty years. I had forgotten how much fun it is!
I know you all will think that my set up is too small and this thing should fly like a cow - But it flies Great! It takes off in around 12 - 15 feet and it will loop from level flight. I was expecting it to fly only Cub like but was pleasently suprised. I love scale airplanes but I love flying more so since I fly alone leaving out the scale details saves alot of weight.
Jeti 40 opto
4s1p Emolis [getting around 16 minutes]
Made some changes from the plans. Put servos in the wing and beefed up the landing gear mount.

Very nice Ed! Looks like your covering came out perfect. Hope you get many hours of quality flying time from her. Thanks for posting!

Only two months. I couldn't stop. Didn't want to sleep or go to work just keep on building.

Nice job - very unusual finish :)
I'd reckon you've done good on the drivetrain selection. Couple of years back, I test flew one from this kit for a clubmate. He'd built it right out the box, strapped a huge lump of Astro 25G cobalt into the glow engine mount with a pair of hose clamps, glued an acreage of 1/8" ply into the fuselage floor and Velcro'd a 16 x 2400 Nicad to it.
Glad I didn't know the weight - but I let him carry it around after picking it up once! Still flew fine, but it only had one speed, thanks to the wing loading - and that was way above Cub-like. I never dared to stall the thing and landing took a lot of planning due to being done at very little under 'cruising' speed.
Yours sounds much better mannered. You can't beat a Cub! I've had three - but the only yellow one was the 16" span profile NoCal rubber powered FF bird. My GP E-Cub and the Sig 1/6th clipwing were red, white and blue, my 1/5th Sig - and if you want a real good J3 Cub kit, that's got to be it - was blue and yellow with USAF stars on the wings.
Yes - all scale too!
Enjoy your baby bear

Hi! I am also an "Old Toad" (72yrs old) and don't like to take the time to build kits anymore so I built the Great Planes 81" Cloth Covered ARF.
I still had about 20 - 25 hrs in the build of this great ARF because it was only built and covered but didn't have any details finished other than the pre-built wing struts.
After installing the tail feathers I had to install the control rod tubes, cut the control rods to length, solder on some metal clevis's.
Like most ARF's, I had to install the control surface hinges, glue the wing together. glue in windows and install all servo's and electronics.
I am exclusively electric so I installed:
E-Flight Power 46 outrunner motor
Jeti 75A advanced Opti ESC
Spektrum AR6000 receiver from my Spektrum DR6 system
2 2100 mAh 3s 15C 11.1V batteries in parallel for a total of 4200 mAh at 11.1V
All-up weight is 7lbs 9oz
I am using an APC 13X8 E prop because that was the largest I had in my stock of props. I intend to try flying it on a 14X7 prop as soon as I can find one at my LHS. This should give me more thrust for climbing out after takeoff.
I maidened it on Thursday Dec 28, 06 with some help of more experienced flyers at our club field.
Today I took it to our city park where we have a 40-45 acre field that the city lets us fly over with almost exclusive use. Just a couple weeks in May when they use it for about 10-12 soccer fields for a state soccer meet.
I did my first total flight without help and it was beautiful. It had been raining most of the day and only a couple of flyers were there. Dead calm air, not even a puff of wind.
On takeoff run I just put in a small amount of rudder correction and the tail came up in about 4ft and the plane just raised up and flew scale like at about 10ft.:)
Flew around for about 7-10 min and made 3 trial landing passes before I finally had it lined up on the runway and touched down with a small bounce and then landed very scale like.:D
I love the combination of the plane and power train, it is just perfect for a J3 Cub to fly scale-like.:D
