RC-Hangout

I had a funjet a couple of years ago, but it died a slow death
The electronics, have been sitting in a box since then.
So today, I ordered a radjet kit to use this power unit.
It will have a 2350KV motor, 70A esc running 4S.
Should be capable of 130mph+

I also threw in a new 4S lipo, a cutting matt, and 1m of adhesive velcro

Faster than a speeding bullet:)

That's gonna be awesome fun, Lee! I'd like to get a Skyfun with upgraded electronics for some fast fun but I think your Radjet package will be faster lol.

The sky fun was a nice plane. It flies fast or slow with equal ease.
But the aerodynamics are not as sleek as the radjet. Wing profile is quite thick.
I was on the fence as to whether to get another Skyfun jet or this.
I'll let you know which I prefer when I get to fly it

That looks wicked fun

Hmm good to see how this pans out:)

That could be some serious fun with FPV gear on it.

Ordered yesterday, shipped today from Holland, so lets see how long Spanish post holds onto it for

Cool:) cant wait for the build:)

Wow, that's an awesome looking jet...

Look what arrived in time for a weekend build
And a new cutting mat, 1m Velcro, and a 4s battery.

NICE!!!!!!!!!!! I love the sound these things make as they go whipping by!

That's great Lee, look forward to seeing that in the air

Cool:) I love parcels:)

So the build has started.
First was to glue the tail fins, and servos into the wings.
Also set the links.
Next was to modify the motor.
I reversed the shaft by removing the C clip, loosening the grub screw.
Slide the shaft through to allow attachment of the prop.
This turns the motor into a pusher mountable motor.
As the C clip has been removed, you need to add a wheel collet.
The motor mounts are laser cut ply.
To allow for the collet, I had to cut up a couple to give some room.
As this will be a speed machine, I have added a carbon spar
Now time for the electronics.

That's great, Lee! It's looking good!

Just did a power test.
WOT I get 42A and 650W.
So it seems I can get rid of the bulky 70A ESC, and put my YEP 45A in there.
Thats a saving of 16g

Looking good Lee:)

Maiden Fail
Looked good for the first circuit, but lost all power, and it went in
Luckily superficial damage. Wing came off, but at the seem, so just needs gluing back on.
Slightly deformed aileron, but I have balsa ones from my skyfun, ready to mount anyway.
Did a range test, and all was good.
I think because a tried my old battery first, it may not have had sufficient power.
Couldn't check if it was a brown out, because as you will see in the video, the battery was 20ft away
Rebuild and try again

That's a bummer Lee, it was hard to see.... Old age I think..lol, glad it's not too serious a crash...
