I flew my Sonic this morning and did a bit of a battery test.
They recommend a 3s cell for this set up but I had to try it out on 4s
The first 2 flights were 3s battery and the third was on a four cell.
I only used full throttle for a second or two and it was really fun.
When I said side thrust I should have said Down thrust🙂

Both this and the Bixler2 with a2200kva motor are very versatile flyers, in the warm weather when there is lift around flights of up to and over 30 minutes are possible.
They both can be flown acrobatically and some flat out fun can be had.

1st flight using Zippy 2200mha 3s 25c and had 46% battery remaining after mixed flying.

2nd flight I used a turnigy 3s 40c 2200mha battery and had 32% remaining after a mixed flight of gliding and power.

3rd flight was my favourite on a Multistar 1600 4s 60c battery which had 46% charge remaining after a mixed flight of gliding and various throttle positions with full throttle coming in 1 to 2 second bursts.





Wot, no Depron?

Looks bloody brilliant mate!

I can feel a depron copy coming on I think to replace my rather broken Gotha....
Whoever said nothing is impossible had obviously never tried slamming a revolving door...

Hi Leigh,
A depron version would be great, nice and floaty for those warm summer evenings (can you remember them?)😃
I could trace round the wing if you like and take some snap shots.
Just let me know🙂

That would be good thanks - just some basic shape design and some idea of thickness and airfoil design and I should be able to knock something up fairly quickly I think.
I've not got a 64mm EDF but I've got a spare 70mm which would work pretty well I think.  Either that or go pusher prop for even more flight time 😃

Ok, I will get on it Saturday afternoon.
I think one of those cheapo 2212 1000kva motors would get it in the air if you didn`t want to break mach 1.
A folding pusher prop would be cool if you can get one, or modify a standard folding prop.
I bought a couple of Racestar 2830 1300kva motors that will go 4s from banggood when they were £6.38 each (gone up now) but a little over seven quid. They push my Skywalker Falcon wing vertical to out of sight on 4s swinging an 8x4.5x3 prop. The recommended prop is 9 to 10 inch, which is pretty good around 1310 grams of thrust,(claimed, I haven`t measured them myself)

I do too😃 It does handle the wind pretty well if the CoG is bang on otherwise it can be twitchy, but that goes for most wings.
If the weather is decent Saturday I will take my Skywalker Falcon to the field to get some comparisons.
The Sonic doesn`t suffer with tip stall like the Falcon but I still like it as it looks like an Horten design🙂

Charge up the 4S batteries. 🙂

I've got a few different ones here I could try and I think I've got a folding prop buried somewhere so might have to dig that out and see if I can make it into a pusher 🙂

Certainly could make for a fun build all the same!

Hi Leigh, I have traced  around the wing and drew the elevons and fin placement.
I will email you tonight.

Cheers Ian,

Quite looking forward to something a bit different - need to get my building mojo back....
