Ceres 2.4 Nose Job

The nose of a 2.4GgHz -friendly Ceres is a tad weak.

I stalled in from 10ft (don't ask) and it cracked the fuz about 3" forward of the rear canopy opening.

Right where the supplied servo tray stops.

It's all kevlar & 'glass there and is ok for dork landings (of which I've done a few) but any lateral stress and it's like cardboard.

So I fixed it by tack welding (Bob Smith CA) the nose back on straight, sanding any bumps and glossy / waxy resin away form inside and adding 4 oz fibral-bonded uni carbon lengthways, and a further layer of 4 oz plain weave kevlar.

Then four 12K tows just under the canopy lip either side extending from the front of the canopy opening to past the rear near the LE.

Then made a new tray which was longer thus extending past the high stress area. The tray was 2 laminated PCB boards with the copper sanded off and laminated with epoxy.
Bonded in using epoxy / cotton flock/ black dye.

I'll test it this weekend weather permitting although it looks like rain.

Hey Dude,

Just keep an eye on it next fight in case the carbon tows have some effect on the 2.4GHz reception.

Range Check

Roger that, range check is a must do. I'm running one antenna in the canopy and the other under the tray terminating in a 90 deg vector. If that doesn't work I've got the longer FrSky antenna leads to try too.

Windrider Servo Frames for MKS 125Minis

Bling Ur Wing
After experiencing flutter on flaps even with the super-duper MKS 125 Minis, and humbly ratifying what everyone here has been saying, I took the plunge and bought 2 frames with bearing supports from Ming at Windrider in Hong Kong.

Expensive but could be worth it. It is quality that matches the glider I'm putting it in.

5 grams ea.

I have those frames on the flaps of my 4.0Xplorer; they were worth the money and weight, IMO.
I think that you will really like them.

I have those frames in my Toba & my Typhoon..they are "Bling" :-)
work good too..

I don't know if you have the extra bearing on your servos (The baudis mounts come with this), but you can get some from Sloperacer (FU-Fix) they work great at tightening up linkages.

BTW I have both ceres and the lift oh and the cyril all F3B lay-ups
My ceres is RDS and she is a peach to fly.

No more flutter

Flap flutter is now a thing of the past thanks to the Windrider servo frames. There's no meaningful slop.

Had a bit of a fly today in very thermic breezy conditions (busted 2 lines) and dived from height with no flutter. Hauling 900g of ballast made for a valid test.

Had some amazing lift come through and the tight thermal turns looked more like DS circuits.

MKS Ds6125 minis are holding up although I suggest the Sanwa / Aitronics 761s / 762s are just as good and a lot cheaper.

If the Ceres is this good I wonder what the FOSA Lift would be like?

Well the Ceres Lift is a stunning model.
Cyril is even better and the fosa is pretty good too.
Andreas Bohlan is flying the FOSA Lift and I'm pretty sure that Jiri is as well.

I have said it before and I will probably say it again, Baudis models rock !

I love my Ceres and my Fosa !!! Can't wait to see whats next ??

Tough to beat a Baudis plane for perfomance, duarbility, and price.

And the availability of parts if you need them!

I keep reading the Cyril is a great plane. What does it do better than the Ceres?

Its easier to fly fast, IMO.
Wing span is less than Ceres, and the tail is exactly the same, so essentially the Cyril has a larger tail.

I do find it hard to distinguish between the 3 models, Lift, F3B Ceres and Cyril I have all three.
There all very fast models.
The ceres and lift have a slower roll then the cyril.
Cyril is fast in speed, launches well and thermals very well too.
Cyril will bang a turn tighter then the Ceres, you need to fly the Ceres and Lift more open.

One interesting note that Andrezj said to me a few years back while I was flying F3F was that the Lift had the fastest first leg of any model.
That includes the FS3, Ceres, Extreme and Ascot.

The lift I found more unsettled with a poor set-up and did take time to tune (But that could of been just me.)
The cyril was my 3rd baudis model and I figured out what I needed to do with the set-up by the time I got him.
I dont use differential for speed, or a little as I can get away with.
I have never found the wings to dig in on the turn.
With RDS on the ailerons and Flap, you can somehow get away with less movement on the ailerons for the same roll rate (I can't figure that out either).

The most important is the servo selection for the vtails.
You need something thats fast and precise.

I have now gone for a mid-sized gyro tail servo with plastic gears.
You dont need torque on the tail, just speed and precision.
JR3500G's are the one I selected, there fast precise and dont cost the earth either.

I dont find it hard swapping between any of the models, as they all pretty much fly the same and look the same in the air.

But for me now the Cyril is my weapon of choice for both F3F and F3B, its an awesome F3B model, even with the white tape I used to fix a dink in the nose cone (Which reminds me I need a new one !)
