Managed a little on the Chippy after some indoor flying at Shawbury.

The wings are all fitted out, servos, undercarriage etc.

I reduced the spring strength, by cutting the heavy spring in half and replaceing one half with a softer one. Need to add some foam between the two springs to act as a damper, but seems to work well.

As everything is connected at the back, then we are able to roughly check the C of G, with my two Rx packs in the nose and a 5S 5000mAh pack up front we are spot on 115mm. I still have the cowl to add so we should be fine without any additional noseweight. The tailplane faffing wa worth it

I will show you the cockpit later when it is finished but I have removed the panels, believe it or not they are made of lite ply!!! I have also removed the covering and re-done the interior in black, looks much better, but you will have to wait for the final pics.

Tony B being the kind soul that he is has prineted me some nice 3D ones that will go in instead. He also printed me a pilot at just the right size Thanks Tony teeth 2

Okay the yellow Chippy is ready to go. All systems are set up and the c of g checked.

Hopefully maiden tomorrow with Chris's, I still have a few little jobs to do but this will do to see how it flies.

I have set the model up on my new FRSky X10 so it will be interesting to see how I like the handset.

For those that thought my faffing around with a new tailplane was probably not worth the effort? Mine has come in at 9.8lbs with a 5S 5000mAh cell. Chris's has come in at 11.6lbs Granted he has used a 6S 4000, but I doubt there is much weight difference between the two packs? He has unfortunately had to add noseweight.

The wings are still a mare to remove, but at least doable.

If you compare mine to the standard Seagull item, I have done away with the stickers, only keeping the maple leaf roundels. I have cut some lettering to copy the Old Warden Chippy 671

Well after staring out the window at glorious weather all week, it looks like my only opportunity for a fly, this afternoon, the wind is building by the hour. So might not happen today crying 2

But i will save your wishes for maybe next weekend

Indoor Nats are fast approaching, is anybody going to join us at Shawbury on May 12th. FO requires a simple indoor model like a foamie Champ, or Cub, fairly simple manouvres. But a terrific atmosphere where last time we all had a blast, and encouraged each other. Nobody really worried about positions in the end. It was an education to see Ian Pallister fly the scale pattern indoors. I will try for a video next time, so you can see how it should be done.

We are trying desperately for a better venue, but alas if we dont get more numbers it isn't economical. The FF  scale Nats venue in walsall is £1200 a day!

So please if you can't enter, try and come along?

 

Cheers

Danny

Well the deed is done, both mine and Chris's Chipmunks flew really well

C of g at around 115mm seems a good starting place.

Cheers

Danny

Thanks Tony, unfortunately the esc melted in mine on the first flight. It was rated to 70A and only pulled 52A max briefly, so just got a weak esc I reckon.

So the first landing was with a new Tx and deadstick. It was fine though. This will be a good model to practice the scale flying routine on.

Interestingly, Chris is flying with an identical motor and prop (15 x 10) on 6S and I am on 5S I didn't feel I was lacking any oomph.

Have to fly them together next time Chris

Cheers

Danny

Aye Chris, very observant! my pilot is very pale and has heard about my flying

Still need to paint him, canopy is just taped on at the moment to allow access.

Cheers

Love the third shot in the first set of flying photos which could be a shot of the real thing but did you steal one of Danny's missing undercarriage fairings, Chris? I might be wrong but the last time I saw the OW Chipmunk it was still in the standard configuration of a single landing light on the port leg - which again, with the exception of the elevator horn could have been taken of the full size.

If it's any use, I took some photos of the OW Chippie some years ago detailing the panels amongst other parts which I'd be happy to share.

e.g.

Martin I've put mine together pretty much as the kit comes, so that means two landing lights. I believe that Danny's doesn't have it's pants on because he wants to make some with a more realistic single light.

I'm content that I've found shots like this, which show a light on the stbd side.

Thanks for the detail, always interesting, but I'm more than happy to have a nice flying model that looks recognisably Chipmunk. Danny on the other hand is just a bit more fussy.

Apologies Chris - I thought you'd modelled the OW one but "013" does indeed wear two landing lights!

Well done, 2 very nice aircraft, may the number of landings equal your take offs.

A word of warning:

FRSky have released a new range of speed controllers, the Neuron series. 40, 60, and 80A jobbies.

The range of features is brilliant. An SBus cable connecting the ESC to the Rx feeds more telem info than you can shake a stick at, from current, volts, consumption, rpm and temps.All that and a BEC that can provide 8A at varaible voltage. All great I hear you say?

Well yes it is great, however the BEC provides DC down the red wire of the throttle channel and the SBUS cable. So if you use an onboard Rx pack, cut both the red wires from the ESC or you will fry the esc. Mine is now fried.

In my opinion there is insufficient labelling in the product manual. The unit is brilliant, but watch the Rx supply, get it wrong and you wont get a second chance....

Cheers

Danny

Here's a very short video of Danny really enjoying his Chippy on only it's second flight.

Thanks for posting the video Chris, I really did enjoy flying my Chippy tonight, and your grin from flying yours seemed pretty fixed too

I cannot begin to convey how nice this Chippy is to fly. Seagull have a cracker in this model

Cheers

Danny
