Very nice!! I wasn't able to down load the video but those pics are beautiful. Any details as far as power system? Did you use any of the Kit wood? 10 oz. seems really light for a guillows.

Terrific video!

I don't know what it is about the larger models but a .40-.60 size(or larger) Cessna like this I could care less about. But This! Truly wonderful.
Is this the 36" span? Steerable nosewheel? Ground handling looked good.

Beautiful finish!

Bravo, Robert

Great looking Cessna, nicely flown and great camera work too! I'm also keen for some details. I like the Magpies and Galahs too

Zimmerman,

Nice job with your Cessna. Did you do a build thread? I have a Cessna 172 I have partially built. I am wondering what you are using for your setup? Power sytem battery, radio gear etc. Also what covering you used? I am at the electric fly festival this weekend at AZ and it is great. Pat Trittle is here and I have had a great chat with him. He also has some nice scale birds.

Zimmerman,
I hope you will also be posting a build thread for it.

How did you finish it, balsa or covering? What about painting?

Please also share about the controls and power system.

Thanks.

Thanks for everyones interest,
i was really happy with the weight, i built one three years back and it was to heavy around 18 ounces,
had to fly real fast and it always tipped stalled.
i managed to save the weight, by replacing some of the balsa . and some of the plastic, and no epoxy only CA.
I used a much lighter film than i normally use, and it is not see throw, it also made covering much easier, it did not crush and distort the fragile frame. I can not remember what it was called it was the first time that i used it,i will look for the label.
The setup was

Hacker B-20-31S 2900KV 41 grams
2.5 :1 gearbox
3S 400 mha hyperion 35 grams
3x 3.6 gram sevos
APC 7x5
12 amp speedy 8.5 grams
run time 10 min only putting back 220 mha
max amp 5.5
I was flying on maybe 10 to 15 % throttle, no deans plug, JT instead I did not take a lot of pic this is all that i have.
I just received a new kit that i am starting soon. it is a bonanza 35V 33" from Acme Aircraft Company.
I hop too make this one around 8 ounces.
I think, if you can save every gram it all adds up and can help in keeping models lighter.
The paint was applied with a airbrush Color scheme was from the cover box, very 60's
Ailerons, elevator, nose wheel steering, no rudder.
The radio is Spektrum the receiver is a little lighter 15 grams the new receivers soon to be released are 3.6 grams.

Hi:

I have to tip the hat to you on this build. You did a fantastic job on this conversion. It looks like a real cessna. Thanks for sharing your process and hope that you do some more. You obviously have a lot of skill at this.

Making the wing secure and easy accesses to the battery
I used plastic screws and magnets.
on the plans it shows a hook like release under the wings for the struts, this works fine if you don't need access to the battery.
the magnets hold good and are not heavier at 0.2grams each.
You only undo two screws and the wing is off.
The elevator Rod is 2mm carbon with a pin drilled threw, for horn.

I finally got the whole Divx thing to work, and I'm glad I did - fantastic video! She looks really rock solid in the air, which is saying a lot considering the size. Well done!

Great job!
I'm curious - you said you did not use the Guillow's plastics?
