i'm planning on using an esskay 400xt and the recommended servo's. havent decided on a prop yet. only issue i have is that i have 6 3s2100mah lipo's and would really prefer not to buy something smaller. will this be toooooo heavy or will it be doable? if it'll ruin the models characteristics i guess i'll spring for some 3s1320mah's as i've been wanting a couple but i'd really like to use the 2100's. Brian, what do you think of using the 3s2100's? anyone tried it? if anything i'll give it a try and if it flies to heavy i'll get the lighter batteries.
Yani,

This was my first build and covering job. If you take your time, it's not as hard as it looks. I found a few threads on RCGroups with step by step tutorials on covering with Solite. One of them is http://www.rcgroups.com/forums/showthread.php?t=52764.

I believe Mark flies his on a 400XT with an APC 8x3.8 slow fly prop, correct Mark? I tried this and it flew well on the clipped wing version with my 3S 1050mAh packs, but then I tried a GWS 8x6HD. Not much more amp draw, but faster and more thrust. Still flies well at low throttle settings, but it's fun to be able to crank it up now and then. (I don't fly pattern aerobatics, mine are more based on chaos theory...)

The clipped wing is quite a floater, and I imagine the full wing would be even more so. I don't think a couple of extra ounces will make much difference. One thing to look out for is the fit of the pack between the battery tray and the former. My CommonSenseRC 3S 1250mAh packs just barely fit and trying to pull them off the velcro without breaking anything can be a pain.

Mountain Models J3 Cub Pics and Video

I posted this in another thread, but I think it belongs here as well...
http://www.rcgroups.com/forums/showt...+models+J3+Cub

Also, here is a video of her first flights.

Oh, a 2000MAh 2 cell Lipo is fine for scale flights. A three cell 1250 is fantastic for aerobatics!

Hope you enjoy. Let me know what you think

Do you guys know if we will be seeing a MM super cub? I know it was in the pipeline, but haven't seen any updates.

I've been waiting for the Super Cub as well. I got to fly Brian's clipped wing Cub at the Arizona Electric Festival back in January and it was sweet until electronic gremlins shortened the flight.

I wanted something with flaps and bought the Hyperion 25 size Cub to hold me over. As soon as Brian does his Super Cub I'll have to have one. It'll probably weigh a third of what the Hyperion does, cost half as much to outfit with electronics and look more scale. A must have for the hangar. He's getting the big SwitchBack ready right now so I'm not going to bug him about the Cub. Yet.....

I am getting into the whole bush plane thing since I put some big wheels on the Minimag and started doing touch and goes off the dirt/gravel path we use as a runway. Now it's time to do something balsa and more scale.

Well, I was going to do the L-4 first, and then the Super Cub. The L-4 is as simple as a new fuselage, so that part's cool. I hope to have the L-4 at NEAT, though it depends on how fast the other projects go.

On the Super Cub, the early versions used the same fuselage, bigger engine, different cowling, balanced elevators, obviously flaps, and a couple other minor things.

I don't think I want to skip the balancd elevators, so it's probably going to be a completely separate kit instead of just a new wing and cowling on the J-3 fuselage. But then again, I could always put the stab and elevator replacement parts in the wing kit for it, but that could be confusing.

So what is the covering your all using? I dont like to see through the covering. What would be the best covering that is solid (non transparent)

Great thread btw
Yes im a newbie.

I used So-Lite on both the Cub and Clipped-Cub on the web site, but it is slightly translucent in the sun. The heaviest covering to use would be Solarfilm, which should be opaque enough.

Solarfilm is a great film..

I have used the yellow on a Cub that is smaller than the Mountain Models kit..

I'm going to get the MM J-3 myself. I got the Hyperion 25e "Bush Cub" too. I built it. Got it all ready to fly. Weighed it...

...and almost fell over backwards. A 55" wingspan J3 that weighs over 3 pounds??? Forget it! I know how this brick is going to fly. Also, it just doesn't look right. I can't quite put my finger on it but the proportions just don't look correct. Either the windows are too small or the fuselage is too tall or the nose is too long or something. It just doesn't look right. I've decided I just don't like it. Anyway, I'm done with Chinese "bARF's"!

I'm ordering the MM J-3 today but any idea when the Super Cub will be out? I'll get one of those too!

Yeh, I agree.. The MM is much more scale looking.. I wonder if we could talk Steve into a 65" version..

I still have the 80" Page Super Cub I haven't built yet!!! I swear I'll get it eventually. Problem is I don't have anyplace to fly anything that big so there isn't much motivation to build it. The "25e" sized planes are really too big for my little field (another reason I haven't flown the Hyperion Cub).

super cub....I'd love to see one 50-60"....flaps, etc...that will be a fun project. I am going to attempt the AP 80" cub but I don't know if it will fit in the car without a wing mod.
