Thanks Jim. Hopefully this won't be another aborted attempt. I've got a lot of unfinished projects that I think I'll just take my time on and enjoy this time.

Mark. It's all dependent on which program I print from as to how the printed size turns out. I'll get it sorted soon. No hurry anyway. I still have a bit of work to do before she can fly.

Joe, posting the picture here probably messes up the size. I'll send it to you directly, which might work better.

The Cub was my first full balsa build, and one of the most enjoyable. It even flew fairly well. Being a newby builder /flyer, it wasn't long till I cracked it up. Poor flying skills coupled with a poor power setup.
Im looking forward to a redo someday.
I took a 16 month hiatus myself a while back due to family issues, but I came back with a vengeance. . Glad to see you are back too! I learned a lot from your posts, and enjoyed the pics and videos you shared. Hope your financial situation improves soon.

Thanks guys. It's going to be a very slow return. I'm not going to make everything a rush job like I used to. I want to enjoy it more this time.

I'm almost completely done with the fuse. Just doing finish work now and the wing only needs to be covered. I thought I read somewhere in the thread that either the manual text is wrong and the picture is right or vice versa about the wing strut tabs. Just want to make certain I get this right. Can someone elaborate on this?

Another MM Cub ready for maiden

I finally "finished" my Cub today. It still needs "N" numbers but they'll have to wait. I used a Scorpion 2205-32 motor with a Castle Creation Micro-10 ESC and a Hitec Electron 6 RX (Yeah, 72 MHZ!) I also used some no name 9 gram servos that I had laying around and never used so in they went. Ended up at 13.6 oz minus battery. I only have two 2S packs and they're both 1300mah so that will push me right to the 16 oz AUW range. I'm sure it can handle the weight though. I have a busy week coming up and the daughter and baby grandson will be here next weekend so I'm not sure when I'll get the maiden done. Hopefully before Thanksgiving .

VERY NICE Joe!!!!
That looks better than any ARF Cub
My L-4 is all framed up and ready for the final sand before covering.... but I have been side tracked building a glider for our up coming summer down under
Did you glue your servo's in to the fuse? I'm thinking of gluing small 1/4 x 1/4 blocks to the fuse sides and screwing the servo's to those.
Enjoy your maiden I'm sure it will go well

Thanks for the compliments Reuben. Yes, I glued the servos in with Shoe Goo. I too thought about making mounts but because the servo loads will be so light I decided to just take the easy way out. They'll peel right off if need be.

One suggestion to make for you. Don't glue in the wing strut tabs until the absolute very last step. I spent considerable time making sure my wing was straight. I built the Pat Tritle wing washout jigs a long time ago and they work awesome. After getting the wing perfect I found I needed to soak my strut ends in acetone so I could remove the tabs. I had to trim some of the strut ends and reset the tabs so as not to cause a twist in the wing. I bolted everything back in place and spot glued the tabs. I then removed the struts and completed the glue process. Now the struts provide full support for the wing but don't cause any twist. I think she's going to fly great. We've got great weather on the way in the next few weeks so she'll be seeing a lot of air time!

Thanks for the tips Joe,
I will triple check the struts before I glue the tabs

Finally a maiden!!!

This is gonna be long winded. Sorry.....

I've gone way too long without flying and just had to make it happen. I haven't flown anything in about a year and was getting antsy. I charged the TX, 2 2S 1000mah and 2 2S 1300mah packs and loaded up the Cub. I went to the local water retention bowl that has a huge flat bottom with close cropped grass. Just perfect for flying. Naturally that area was being used by the cricket players today. Cricket? C'mon, who plays cricket other than Brits. That meant I had to fly in the lot above that is crushed gravel and rutted dirt. Less than ideal but what the heck. I wanted to fly!

I don't get nervous during maidens even after this long without flying. Then again I fly mostly Mountain Models. I KNOW the plane is going to be right from the start and I was NOT disappointed!

I went with the 1000mah pack for the maiden even though the CG was at the rear of the spar with this light pack. I prefer a rearward CG on everything anyway and wasn't too concerned about it. There was zero wind so I just pointed her down the least rough section of ground and very slowly advanced to about half throttle. She lifted her tail and broke ground just as scale as you please. Gave me goosebumps it was so sweet. No trim changes needed at all during climb out. On the 1000mah pack I flew 13 minutes before changing packs. On the 1300mah pack I flew 16 minutes. Between those two packs I realized I haven't lost my touch and go mojo. I shot no less than fifty 1 wheel, 2 wheel and 3 wheel touch and goes. Every one a thing of beauty and was exactly what I was trying for each time. A testament to the flying quality of this bird and not my flying skills.

I realized after changing to the heavier 1300 pack that she flies better just slightly nose heavy. Less tail drop in turns. She likes a lot of aileron throw and a pretty good bit of rudder/aileron mix for those really pretty coordinated turns. Aileron rolls are ugly because of all the rudder mix I have but I'm OK with it because this isn't an aerobatic bird. This is the best laid back, no stress, cruise around, touch and go bird I have. I knew it would be nice but I wasn't expecting it to fly THIS good! I may go ahead and get the clipped wing for her but I don't know, I'm just so happy with her as is. Wish I had flown her when I finished the build months ago. Stupid me.

I hope your weather improves soon Reuben. I ran out of excuses today. Low 60's with a little overcast and at times no wind. When the wind did kick up it was just enough cross wind to add to the fun.

I now own, have owned or have flown virtually every powered Mountain Models kit produced but this one really surprised me. I was smiling or laughing the entire time I was flying. The only kit that would score slightly more overall points is the SwitchBack and that's only because it's more aerobatic. For low speed relaxed fun the J-3 Cub simply has no equal. I can't wait for next weekend so I can fly some more.
