Brian 245 - you will not be disappointed: my Ivan's Auster is still flying (even after certain "incidents") and gives me great pleasure with its ability to fly really slowly. I made a few mods to take it away from Aiglet to AOP status, but otherwise it's all Ivan.

BTW, you should see him throw his Aiglet round the sky!

Except for the canopy it is a really simple build. One of these days I'll make a plug for Sparky to work with.
Wow! I had not known that. I'm pretty out of it these days. That's great to hear. The Chipmunk is a great flying model with lots of capability and I personally think it looks gorgeous.

The canopy is indeed the tough part and if you got Sparky to make one that would be great. I went through all manner of travails getting one made for my model. I built a plug but it was so big most small-time vacuum forming guys couldn't work with it. I finally got a guy with a rig large enough to do it but I don't remember what happened to the plug after, it might have been destroyed in the process. Anyway I don't have it anymore.

Keep us posted on the kit! And thank you to Mr. Bradley. If he wants to stay busy I'm sure the Ivan community would lobby him for many more.

Brian, your Auster looks great. Having flown Ivan's original, I can pretty much assure you, if you have ever flown any RC whatsoever you will find the Auster easier! Still, it never hurts to have support present for any maiden.

Let us know how it goes!

Way back there was an outfit called Skyway models who did a plan pack and canopy for the Chipmunk. I think it was probably about 52" span - seemed big at the time... small now.
I don't what became of that.

My own Auster was a T7 - back when brushed motors and Nicads were all we had. All those batteries on the floor meant that although it would happily enter a bank it was a job to come out of it . Centrifugal force took over! Had to sling them up under the wing to cure it.

I know Trevor used a commercial canopy for his Chipmunk, and very smart it looked too. Perhaps he can say which one it was?

My Chippie uses a canopy from Syd King's mould. It's slightly oversize so the fus needs to be built a bit wider than on the plan. Whichever canopy you use, it is a good idea to have it to hand before starting work on the fuselage. Luke's experience brought that lesson home to me!

If you want to use the Syd King mould, just let me know and I will look up the details for you (the mould is held by a UK vacform supplier).

Since the fuse shape is fixed now I think I'll make a plug for Sparky to use. If I ever get that far I'll make up the kit as a complete one, with wire, canopy and such.

It also just so happens that I had my Eagle Tree recorder in the plane for the last 4 flights. So, GPS speed was recorded. Takeoffs happened at about 25mph. Landings at 30mph flaps up, 20mph flaps down. Top speed was around 65mph. I was usually cruising around 40mph.

Plane hit the wire at about 25mph

Suppo 2826/4 motor, 3s5000, and an Xoar11x7 prop.

Here is the build thread.

Here's the thing Luke:

Charlie's built an Ivan's model and flown it, so his picture should really go in the Hall of Fame. No no, don't wait for a rebuild, he may never get round to it and I doubt whether his pilot was properly insured* so let's have the Hall of Fame updated.

*You know it makes sense to have full SPNOKA cover. You too could hit a 3cm wire with your 40 cm model.

ROFLMAO.

Thanks Mike, I knew I could count on you. Unfortunately for SPNOKA, the pilot is just fine. A few bruises from the seat belts but he walked away (actually he stayed in the cockpit as I carried the plane away).

You are correct, it may be a year before I can get it back in flying condition. All these people keep wanting me to send them kits and I still have a day job on top of that.

What! We have a Hall of Fame now? How is a fellow supposed to remember all this stuff...

But Mike I agree with you completely. Charlie, you now have the distinction of being the only person with a crashed airplane in the Hall of Fame. What I should have said earlier, is welcome to the Ivan club. We're happy to have any of the New Mexic-ians with us, the longer the hair the better!

Edit: Charlie, I don't see the Chippy on your site yet, but let us know when it becomes available, and I'll add the info to the beginning of this thread. In the meantime I've put a link to your and RG's build thread.

Well, what I mean is, he's the only one whose picture in the Hall of Fame is of the crashed model! (I think.)
