View Full Version : Se5a ww1 biplane scratch build

10-16-2009, 02:45 PM
I have just finished scratch building a SE5A bi-plane. It has taken a while as I lost interest for a while, but once I had some rec leave from work I got stuck into it. It was first made for a gas power model but I modified it for electric as I have converted over to the dark side. The plans were from the Nick Ziroli plans that I got from ebay. I have been waiting for the perfect day to test fly it, as has been windy as buggery here on the Gold Coast Australia. Thought I would post some photos. Will try to test fly tomorrow at Hinterland Flying club.

Nice plane! That thing is big. What's the span?

That motor and battery are scary. I can imagine they must be up there in price. Would love to see a vid of it flying.

The motor and battery cost about $120 Australian, from Hobby city in china.

Wing Span is 54 inches.

Went to test fly it today, way too windy, 15 to 20 knot winds, egged on by mates they suggested to taxi around on runway, put on quarter power and she lifted off the runway, after I myself flicked throttle off and put it down, not the best conditions to try and fly for a maiden, put too much work into plane.

Attached are some photos of the cowl battery set up.

I have also included a couple of other electric planes that I have, all are good flyers. The f16 has a Scorpion s11 1190 kv, 10 x 10 prop. The f35 has Turnigy 35 30 1700kv motor. Ducted fans are not powerfull enough if you are not prepared to spend a lot of $ on them.

Here are some pics of the maiden flight I did today. Nothing more satisfying than building from a plan and then it actually flys.:tc:

Superb KD! Nothing like building it from scratch or a kit. When it breaks ground and flys, there is no other greater feeling of accomplishment. A part of you is flying too. I prefer to build. Sadly the manufactuers only want to produce ARFs for the "I want it now generation". That's why I collect kits! Now maybe the next plane will be a German fighter.....All the Best, marty

yep I know what you mean, scratch building seems to be a lost art, when the arf crash and burn you go and buy another. By building you certainly learn about the characteristics of an aircraft and why they fly and how to make them fly better, eg building in washout make em light, etc.
