nnChipmunk v2

An small update on my project of the nnChipmunk.
It flew
. Made some under powered flights with the Turnigy G10 engine.
Here my servo setup with pull wires for the rudder.
Screenshots of the boring under powered first flight movie.
Now working to get some more umpf in there!
Needed a bigger landing gear for the 18X8 prop

Yeah, two servos. gives me some feeling of safety. Are very cheap servo's.
Handling don't know really. With this engine I could not take risks so flew some rounds. It floated a lot though, probably because the setup I flew it with was about 4 kg. That is really light for this size i think.
Finished with the 30 CC I hope to keep it under 5 kg.

Well i finally got started on my V2 super chipmunk. I desided to have alittle fun with this one and make it a little test project for later on when i build my 150% chip
So i first i desided to add landing gear to the build. Almost gave up on it cause i wasnt sure on how to make a steerable tail wheel(without running another push rod or sept servo). But i was able to pull if off running it threw the fuse and attaching it to the rudder.
Then i moved the aileron servos to center wing inside the fuse. This was more of a test on the speed wing for the belly landers. Plus i like it this way cause it gives the wing a clean look.
And for my latest idea. Removable night flying led mounts. So i can add them to any fully painted build. Got the idea from the larger scale gas planes that have led wing mounts to light up the whole aircraft
Progress pics so far
Have more pics. But i keep getting failure to upload on them

Nice jayz! Flying in the dark is fun!
I never made a tail wheel in my foamboard planes , just a stick and that works. Not as good as a tail wheel though. Have an Exra with a tail wheel and it makes live easier, true.
Making a bigger plane is not difficult, just some common sense but think about the thickness of your wings.. I made a mistake by just doubling the size of the spar which gave me a 3cm thick wing (instead of a 4 cm)
The only thing that sucks with bigger planes is that you have to go ballistic on the power setup. If you go for 150% your airplane becomes about 3.4 times as big I think.

Good news! My planes are coming soon and I can start building. It'll either have a 35-48 900kv with a big prop, or a 35-36 1800 with a smaller high pitch prop. I'll also do the speed wing because I don't want the wings to fold
Have you decided on a team aerobatics paint scheme Nic?

What happened at 2:45
What do you mean?

Good choice! I hadn't thought about color yet.. Ideas?
No big deal, I see you ending up in a position (at 2:45 at the clip, upside down flying away) where I probably would have crashed my plane. The movie cuts right there so I wondered what happened..
I flew my gas engine today on the nnChipmunk! Have movie but have to upload it. Will do tomorrow.
As promised.
Here my swappable power pod.
Ready to fly! I painted the wing because of the fuels. I found out that gasoline is much less aggressive as nitro fuel is. It is not affecting the paint at all! Also gas engines throw out, or use much less oil than the nitro ones. This two stroke engine shakes much more as my nitro four stroke does though.
Some shakey footage (but google is working on that!)
Only flying half throttle because the engine is brand new.
The tail stick works well with this big rudder. Steering is easy on the ground.
Now have to do something on the looks.

Photos of chipmonk V2 - built.
Have not got to fly her yet as it is high winds in Cornwall Uk and has been all week.
This is the finished product - still need to tidy up a little but 99.9%.
This is my compartment reinforcement - the skewers are run full length. I was rough when building and warped original so built reinforced replacement.
Because of the heavy English foamboard (I call it English Oak it is so heavy) my batteries always end up right at the nose and I often move servos away from tail just to get CoG right. This solution I like - ESC below pod and 2200mah inside pod.
I am loving this plane even though not flown yet, she is real easy on the eyes! I added exhausts cause got fiddling with scrap foam - kinda like them.
I must stop looking out the window at the trees, the wind is dropping but still too strong, just too gusty for a maiden.
Thank you Nerdnic - I really enjoyed building this one.
