Ah, fuggit. You know what?... I might just go down to the LHS tomorrow and grab a Spektrum AR6115e

I'll see if HURC will take the Power Up Rx back. I know a cheap way I could ship it.


Maybe pick up the Lemon at some point just for a back-up so there's no down time if I ever need warranty.

I would have thought that the extra bracing would be towards the nose.
How is the camera held on, Velcro? It could come off in flight. Or even a bad landing. it would be hard to find in grass. It does happen. I would suggest that you had a lanyard fitted.

Actually the carbon rods flex quite a bit and act like a shock absorber, I tried a few different diameter rods and settled on the 1/16" ones which gave enough strength but also flexes with about 5lbs of force.. I landed about 20 times in my very rough pasture today and the LG bounces right back to the original position.

The camera mount I constructed with an old plastic gun sight from a pellet rifle, I mounted the camera body to the ramped sight with screws that attach from the inside of the camera housing into the plastic sight and then screwed and used epoxy to secure the ramped sight to that rounded piece on the battery door. It is pretty secure but I probably will take your advise and use a lanyard as an insurance policy..

I really appreciate all the advice and knowledge I have received from everybody here, this is a great group of people!!

Here are few pics of the LG mod flexed and the camera mount..

Thanks a bunch, I ordered something that looks identical to those from hobbyking, we'll see when they get here if they work. If not I'm only out a couple bux.

They should be fine if they're for a 4mm shaft (4mm ID or inside diameter on the adapter). If they're from HK I'll bet they might be the Turnigy one that Chompwat just posted a pic of a couple pages back.

Depending which props you use, you might have to ream or drill the prop hole to fit on the adapter which is normal. Some props come with a large hole and a set of different size inserts.

I flew the ealier model that was powered by the Nimh batteries a few years ago, which flew just fine. Recently I bought a cub, and did the brushless upgrade, with the eflite 480, 30 A esc and new 9g servos. The trim is fine, it turns left and right, up and down, no problems, but everytime i try to fly it, it will go up and to the right, eventually crashing . Everything looks perfect on it before take off. I dont get it, this plane from before flew so easily with duct tape and other battle scars and now i have a new plane that cant into the air. The wings are centered, I use half throttle for takeoff and it seems nose heavy when taking off from the ground, when hand launched it does flips. Any suggetions would help.. I checked the COG it seemed to be where it should, unless Im missing something here i dont get it. Does the brushless motor and mount weigh more than the brushed gear box and motor, thinking about putting the old motor back on cause I wanna fly. I did all my research before ordering the parts, and thought it would be no problem.

Have you got sufficient offset on your motor?

How did the plane fly before you did the B/L conversion, you haven't said!
If it was fine before then clearly something has changed!

The weight and the weight distribution will both have changed from the stock set up.

You haven't said how you have mounted the new motor. Have the stock down thrust and side thrust angles been retained? Where is the ESC positioned.

What size Lipo are you using and how is it mounted? Again weight and COG will be affected.

I don't understand when you say everything is trimmed fine, how have you managed to trim in flight if it is flying as you say?

The cub will fly straight out of the box on a stock set up, so if nothing else has been altered the answer lies in the changes you have made.

I bought the mount from custom rc parts,it has the angle on the mount aswell, the esc is velro'd inside the fuse

Im usign the hobbyzone 1300mah that it came withI don't understand when you say everything is trimmed fine, how have you managed to trim in flight if it is flying as you say?

When i say trimmed, the elevator is aligned, aswell as the rudder before takeoff. And they move fine left,right, up,down

I use the ar400 works great and its only $29

First off I would suggest checking your COG. The cub should balance at a point 2.25 inches rearward of the wing leading edge. I find slightly nose heavy to be preferable. If she comes up tail heavy try moving components forward and as a last resort add weight.

The cub naturally climbs under power, this will be exaggerated with the 480 B/L motor.

You can increase the tail plane incidence by adding a strip of 1/8" balsa under the leading edge of the stabiliser which will counter this a bit.

Use the low rates on your Tx for starters.

If hand launching try and let her get enough airspeed for the control surfaces to be effective, then back off the gas until she levels out.

Trim for level flight at around half throttle, and it sounds like you need a bit of left trim too. Visually the controls may look straight on the ground and this has to be the start point, but in the air small amounts of trim make a big difference.

I'm sure others will chip in too! Good luck and keep us posted!

Will do! Thanks for your help

That (and most other) brushless setup will be lighter than the stock setup... you'll be tail heavy if you didn't do anything to counter the weight lost from ditching the brushed motor + gear box... like put the ESC in the nose with the motor... among other things.

I need auxiliary channels (not AIL) for certain accessories that get turned on and off from my Tx, like my switched landing light.

i.e. gear, aux

Am also trying to shave a few grams here, few grams there... where I can... to offset some of my mods and keep it as close to stock weight as possible. That Lemon-RX is feather light which is appealing.

Sorry for the off topic but I seen this in my Park Flyer mag.
http://modelaero.com/Merchant5/merchant.mvc?

There was a popular one out a year or two ago. Could fly off the grass, onto water, snow, whatever. It was more square and I think it had large flaps. Awesome flying! Can't remember the name.

Move the battery forward. Cut foam or battery box away. Whatever it takes to balance out.

Dude just fly the damn plane. Youre playing barbie doll with a cheap foam plane made for beginners to crash and learn and have fun.

A cheap foam plane that I'm making into something that's more than just a beginner plane to be crashed... I already have one of those ... and this one ain't so cheap anymore with all the stuff I've done to and am still doing to it. If I crash it due to my own dumb thumbs that's one thing and I'm fine with that... if I crash or even lose it due to faulty electronics that I knew had a reputation before hand and went ahead and used them anyway I'd be kicking myself.

My goal with this project, before I even bought it, was to turn it into something that I wanted if I could find it, but it apparently doesn't exist... a durable foam 1/8 or 1/9 scale Super Cub that's easy to fly, is easily repairable and has readily available parts, most of which I can get 7 days a week 10 minutes down the road from me. What I'd ideally like is to have something like the Pat Tritle designed balsa kit Super Cubs but I don't have the experience to build or, more important, repair those types of planes. Even with all my scale mods this thing will have, short of it going up in flames, there's nothing I wouldn't be able to repair on it in an hour or over night.
