That's a great looking cub and some really good pictures. Thanks for sharing them. They are now in my screensaver.:)

A lot of people have complained about the Wattage 400 J3 Cub, not this guy, I love how it flys and it looks even better !!!
01-13-2006, 12:29 AM
Tracon welcome to site, I have a question, that Cub doesn't come with ailerons does it? If not how hard does it look to install them......Great looking Cub by the way. I really wanted that one but I don't like flying with out ailerons...............GW
01-13-2006, 05:22 AM
The Cub flys great without ailerons, but installing them looks pretty easy...
Just cut down the trailing edge and get some aileron material and hinge it in...
01-13-2006, 06:18 AM
Wow, that is fantastic. One of the best cubs ive seen in a while.
01-14-2006, 12:31 AM
Thanks Sam, I think I just found my next project.......Cliff

Got a little movie clip from the lake the other day...
check this out...

Tracon!! That's an absolutely great looking Cub and simply fantastic photos! I know from experience that it's not easy getting action shots like you've posted here. Kudo's to Barney AND to the photographer!

Nice little clip, Sam. Will you and Beverly make it over to Chilliwack on Sat.?
02-08-2006, 02:32 PM
Due to your insperation I've got my wattage cub flying too. Got the floats last week and they are mostly built. Just some detail and mounting to do. I like ailerons also. Gonna strip the wings, cut it in half and remove the dihedral and put the ailerons on it. Right now its flying with a e-flight 370 (1360kv) on a kokam 2s 1600ma pack. Eflight 20amp esc. Best e-plane I've flown to date. The maiden was perfect. I was just gonna toss it and motor it to the ground to check balance. It flew straight and level so I throttle up a little more and flew it. Almost no trim change needed, one click of down elevator. It floats real nice and has a nice slow glide to touch down. I used .032 wire instead of the big wire pushrods and smaller eflite control horns glued on with goop instead of the supplied control horns. I've read the complaints about this plane, guess I got lucky.

FYI ya'll. I found some Krylon spray latex paint. Its foam freindly. Doesnt spray too well in the cold but it seems to lay down alright once its dried. Got it at Hobby Lobby (the craft store not the hobby shop).
Do you have a cooling hole on the fuse to exhaust heated air? Or is it necessary?
02-21-2006, 07:51 PM
I have three intake holes in the front of the cowl, and there's a tiny bit of a crack where the back end of the cowl meets the fuse where all the warm air passes out of the cowl...
I flew last year at one of our big even fly-in's and the temperature on the field was 36 degrees celcius and the motor was still able to blow enough air through to keep things cool...
Hope this helps,

Can I ask where you bought your Cub and floats?
02-21-2006, 10:12 PM
My Better half, "Beverly" won it in a Canadian Electric Flight photo contest, but you can purchase them quite easy from here:
The floats are GWS Floats...
02-22-2006, 12:44 AM
I went ahead and placed an order. I can see why Bev won the contest! Beautiful photos of a beautiful model!
02-22-2006, 01:18 AM
If you're thinking about putting it on GWS floats, you may want to order a couple of extra sets of the landing gear, they're pretty cheap and that way you can have one set for wheels like I did and two sets for the float braces...
Landing gear sets sold here:
I made scale farings and working shocks for Beverly's Cub, I can change from floats to wheels in the time it takes to change 8 screws !!!.
Here's the cub on wheels:
All the best,

Well, Barney the bush pilot went under the knife the other day, after a lengthy surgery he had a few extra unnecessary extremeties removed (Legs) :D
I can't believe how perfect he fits into the cockpit of our Wattage 400 J3 Cub !!!
Here's a few pictures of our happy bush pilot ready for duty !!! :rolleyes:
Hope everyone is finding silly projects inside out of the weather like we are...
All the best,

Ready for water maiden. Tracon, have you weighed your since all the mods were done. Just curious. Still have to do the new wing. It will be straight (no dihedral) with ailerons. One of my wing struts broke during handling so I'm leaving them off for the time being. I have some K&S brass airfoil tube to make new struts when the new wing is done.
edit: Put in a bigger pic.
02-26-2006, 11:28 PM
Thanks for the links Sam! I just got me Cub and am also going to flatten the wing and add ailerons. Hey, I love your little cylinder heads... Where did you get those? I didn't see them with the kit (but I haven't looked that hard...) Barney looks great! Awesome detail!
03-16-2006, 03:24 AM
Just a note to let you know, Mrs Tracon and I now have our web site up and a bunch of our pictures have been up loaded to the galleries...
We still have many more to upload...
Hope you can find some time to stop by for a visit...

I was so inspired by Sam & Beverly's work, I wend ahead and got one too! Here are a few pictures. I haven't assembled the floats just yet, but the lake is going to have to change phase first anyway :rolleyes:
I went ahead and modified the wing to remove the dihedral and add ailerons. I tried to salvage the original covering, but I ended up recovering the entire wing. That did give me some original covering left over for some touchups on the fuselage. Don't laugh too hard at my little cylinder heads... I think I left them in the dryer just a wee bit too long :o. I can't wait to take it out to the field! Oh, I added a little battery hatch underneath and modified the landing gear for looks and strength in anticipation of my less than stellar landings. This is to replace my GWS foam cub and is a vast improvement! Should be great fun!!!
Oh, Sam and Bev, Great site! Lots of fun and great photos!! f.
03-21-2006, 02:29 AM
Great looking Cub Franny! What kind of prop is that?
03-21-2006, 04:11 AM
It's a Zinger 9/6. I spray painted the tips... I have now idea where I got it... I might have had it from something a while ago. It is super thick. I remeber my Dad's Cub had a wooden prop with red tips. Neat airplane!
03-21-2006, 04:51 AM
Great Job on the Cub !!!
We sure love our Cub, whatcha got in there for power ???

Barney the bush pilot takes flight in our Wattage J3 Cub today and survives to fly again...

Those are beautiful shots! My compliments to the pilot and the photographer!
04-11-2006, 12:55 AM
Oh, Sam.. I forgot to get this for you: The motor I'm using is a KMS KBM 31/21 Brushless Motor 57.5g 1750Kv I got from hobbie people. I used the KMS 18A speed control (http://www.hobbypeople.net/gallery/108025.asp) I wish I could say I really like it, but... The price was like half of my usual E-Flights and CC speed controls, but the motor and the speed control run really hot and in turn the battery (3S LiPoly 900mA) runs hot too but the worst part was that on the first flight I nosed over on landing in the grass and it bent the shaft! It is really thin and soft... So,... not the best experience... The actual flying was a bit weird as well. I was really anxious to see how it would fly with the flat wing and the ailerons... It was a bit squirrelly actually. Surprising neutrally stable. I had the CG right where the plans said, but it pitched up in the turns and wanted to stall. The motor put out like eight times too much power as well so I think I'll add a little weight low in the nose and use a smaller prop (8/4 slo flight). That should help a bit. I think it also needs a little washout at the tips. Also coordinated turns are a must as well... So, my conclusion is that maybe a little dihedral would help. I still have to put the floats together...
04-11-2006, 06:30 AM
Franny, your description of your Cub's flight sounds like every other flat-wing Cub model that's ever flown:) . They ALL need some washout, and rudder co-ordination to turn well. My 81" Hangar 9 Cub flies exactly the same. In addition to washout, make sure that you have lots of aileron differential; try for 4 times as much up as down on the surfaces. This will greatly reduce the adverse yaw, which is most of the reason for the nose pitching up in turns. Other flat wing models are similar, as my old Unionville 72" Beaver had the same characteristics, and responded to the same changes. Once set up properly, this type of model can be flown very realistically, and make the pilot look pretty good.:D
04-11-2006, 06:37 AM
Thanks for the kind feeback...
Sorry to hear about the issues, you'll get them worked out and have that bird flying great...
Good luck and good landings..
04-11-2006, 04:48 PM
Thanks Brad. Good to hear your explanation. I'm fine with the co-ordination in the turns but the pitching was driving me nuts. That makes sense to add aileron differential. I'll give it a try.
04-11-2006, 05:53 PM
Long time no see.....
I got my new job, don't know what's going to happen with Chilliwack...:confused:
They have me on call and it's really turning things upside down....
I guess we'l have to see how it plays out ...
Good seeing you here...
04-13-2006, 05:15 AM
HEY,Sam , great to hear that the course paid off! Looks like you're set for years now, as long as you stay off the now notorious Northern route:( . We'll miss you and Beverly at Chilliwack, if you don't make it this year. Who will take all the great shots that Bev gets every year?:confused:
04-17-2006, 09:00 PM
Have you got that thing flying yet buddy ???
04-17-2006, 09:42 PM
No, I'm a total slacker... I've been working on a large powered glider actually... I need to make those mods to the ailerons. I played with the Cub in the Real Flight Sim, but I couldn't get it to replicate what I was seeing with mine. The weather is supposed to be great this weekend though... Thanks for asking. I'll try to get some good pictures this time!
04-20-2006, 02:37 AM
Put some GWS floats on it and make a seaplane. Worked real well for me.
06-01-2006, 08:43 PM
Just stopping by to pass on the link to our float fly pictures from last weekend:
Mrs Tracon got some great pictures of our Cub at the float fly and at the field..
