Maiden my 90g 2S bruslesss on Sunday. It was about 15mph. Toss with 50% thottle - nose dive on the second toss and ended up with broken wing, fuse, and nose. Glue everything up yesterday and taped with several layers of packaing tape on entire fuselage. Now it weights 120g!! Today's wind was quite calm <5mph. Have control horn set at furthest position and toss with 30% throttle. It flew nicely today. At 50% throttle, it climbs and stall a bit - will have to recheck my balance. Haven't dare to go beyond 50% throttle yet. Cannot ever complain about not enough power now!!!

2S 350mAh Zippy
10A ESC
2020 3500kv motor
3.7g servo
Also put in battery alarm set at 3.3v. I flew for 10 minutes without triggering it.

I may install some LED strips inside the fuse but we'll see if it'll grow through the fuse or not.

Hi Doug,

Yeah - It might require some re-engineering to work perfectly. It's a Turnigy 1220 from HK. At 10400Kv, I plan to use the stock spur gear and gear box (new one) to mate into the champ. It may fit and run easier than a BL outrunner, certainly looking more stock. The motor weighs 8g, I'll have to verify what the stock Brushed motor is - anyone know?

Between the extra ESC and wires, I should be able to get good balance once the test run is complete. Using a (need to verify this!) 5:1 step down, the motor should look like a ~2100Kv unit - with 4.2V, that's WO at over 8500Kv, just about what one might see with a BL outrunner. We'll see! I may even run it direct, but if the torque is not high enough, it might load the motor with the prop. I plan to use the 4.3"x2.8" mosquito prop (what I use now on my other champ). (the 110x80mm) - part of the fun is trying stuff out - that's what makes the hobby really interesting, hey?

Kind of a fun little project, and I have a BL outrunner to use in lieu if nec. But for $8, I think this is worth a try. Motor should be in around end of June.

Basic Mods

You guys are crazy and this thread is great!
My champ isn't even here yet, but you got my hot for messing it up already.

I understand that the Champ is great out of the box, but I'd like it to be nice and stable and stay this way for some time.
So, what essential modding/reinforcments should I do before flying?

From what I gathered here and elsewhere, this is what I plan to do:
- clear tape on leading edges and tips of the wing, as well as
- clear tape between the landing gear "trousers" (the yellow pieces) and the fuse
- bigger wheels (Mosquito or L-4 Grasshopper wheels as main, Micro trojan T-28 as tail)

Maybe later
- wing struts
- LEDs
- battery holder for 250mAh E-Flite batteries (got some from the MCX Tandem)
- holder for 808 keychain cam with adjustable viewing angle

Is it usefull to glue small pieces of carbon rod inside the fuse to strengthen the motor area?
And how about carbon rods under the wings/on rudder and elev?

Anything I forgotten?
Sorry, I'm pretty excited and want to get it right.

Thanks & Cheers,
Mac

They say anything added on the tail makes it. Tail heavy.

Tail is the weakest link... especially where it connects to the fuselage... so adding clear packaging tape to reinforce that will help... I've went through three within the past couple years and am waiting for my replacement to come...

I have a question about key chain camera's to run on my champ... What are your guys running?

I don't want to go extremely expensive but want something that will produce good video, if possible HD... Also maybe something I can get on Amazon...

Your wheel mod sounds a bit large. Carbon Cub wheels are twice stock size and look great. Grasshopper wheels are twice the size of the CC wheels. The extra weight will be noticed, best to keep it light IMHO.

I'm a bit conflicted right now, since I was stumbled across even bigger wheels (North_of_49's T-28 wheel mod) in the meantime.
So maybe the Mosquito wheels are the sweet spot for me.
Guess I'll have to decide when I actually have her in front of me, to get a feel of the proportions.
Can't wait.

if these wheels are super big, and if you can slice them in half, maybe tehy will work?

you do not want a bigger wheel for reasons what if wind catchs it. so on. I use dubro 1.23 they do just fine, can opt for way larger, but to large is too funny.

keep us posted

Yup, my T-28 wheels tires (didn't use the wheels)have been great for short grass landings, but they're for the main... looks like you said for the tail?. They're only about 3mm larger than what I really want to have a scale version of the biggest bush tires I've seen on some Piper Cubs... I have pictures and video for proof I can run them down a bit on my bench mount belt sander if I want them perfect

They work great the way they come. Wind hasn't been a problem, in fact, these wheels help stabilize my Champ in a breeze (more weight and inertia).

Large is funny? Here ya go, fishy...

@North, Thanks for the instructions on the bush wheels installation. They look really cool. Modded the carry case. She fits nice. Half way through the project I was starting to wonder about the COG. I'll be Dang, it was spot on..

Man, can't wait to fly her

No no, the tires of the "big" T-28 for the main, of course,
and a single ultra micro T-28 main (or Vapor/Sukhoi wheel, if it's too big) for the tail.

Sounds good, and even if weight became an issue (e.g. if the keycam is on board), I can always buy a stock landing gear to pop in when needed.

Nice video.
In fact it's this funny/cute look I'm going for.

These ones aren't bad, too. It shows of the gear better and the text states the dimensions (35").

Mac, ok I gotcha... didn't realize there's 2 different size T-28s

Yeah I love the huge bush wheels on the Cubs and Champs (Champs are more rare)... to me, it's the difference between actually liking the look of the plane or not... I wasn't interested in either one until I saw a video of the real CubCrafters Carbon Cub with big ass tundra tires

Hi, first time posting on airplane threads.. I tried rc planes several years ago, with disastrous results. Started reading up on the Ember 2 and bought one; it's been micro park flyer fever ever since. Next was a Night Vapor, looking for something slow to land on our rc carrier, then a micro stik, to carry one of those 'gumstick' cameras around.. that worked out better than I anticipated. By far the most versatile purchase has been the Champ, which has proven to be the most intuitive and easy to learn on plane in my inventory. I've made a few mods: Never flew the Champ with stock wheels, instead opted for 1-1/4" dia. foam wheels from an old twin motor 'steer by shutting down one motor' plane. I've amassed about 9 batteries, and didn't want to velcro them all, so a rubberband holds them in the slot. I cut back the yellow fairings so they don't dig into the the fuse (as much) on those hard, blacktop basketball court landings. (Note the white 'beard'). Still flying everything else original after maybe 125flights.. Batteries range from 70 ('Vapor) to 190 mA Miniaviation. One terrific ounce of entertainment!
