After 3 months of building the K60G turbine powered JTM viper jet it was ready to maiden. Most of the test flight was at 1/3 throttle or less. Due to the wind shifting direction during the flight I had to attempt to land in a cross tail wind and it just would not slow down

Managed to finally land with almost no fuel left!

Looking forward to gradually increasing the speed over the next few test flights to see the true potential of the engine

Special thanks to Ernest from ERJETS in Singapore for his fantastic customer service!!

Check out the comments below for the complete build!!

I am still building the Jetlegend F-22 raptor

These are an amazing flying jet but it is going to take a while to finish it as it is a kit and you have to do everything from gluing in the formers through to paint and decals

Oh, and there is no instruction manual!!

Power will be provided by a kingtech K140G turbine

Here is the link to the build thread

After a successful maiden flight the 64mm edf hawk testbed has a coat of paint and a few waterslide decals. The weight is now up to 1650 grams (including the 6s 3000 mah battery) so it doesn't float like a stock 3s T-45 but still flys well due to the 1500 watts of power and almost 2kgs of thrust on tap.


Since this is the testbed, I haven't sanded back the mold dimples in the foam or smoothed the foam out with primer putty.

The pilots are HK T-45 pilots.

The wings are still held on using the standard hardware. I am getting gamer with the positive G loads, but still a bit cautious with negative G.

During flight testing the hawk has proven to have a large flight envelope, but it really needs a rudder for the cross wind landings and flaps to slow it down in crosswinds. With a headwind on landing it slows nicely and floats in. In a crosswind it just does not slow down and takes almost the full length of the runway to stop

Here's the vid of my hawk maiden with the extreme rc 64mm alloy fan on 6s.

So far the mods are

-New fan unit
-MG-14 metal gear servos for the elevator and aileron (in stock locations)
-HK dsr retracts with 7075 suspension strus hot glued into the foam (Super dodgy, but that is intentional so I can see what I can get away with)
-1 6mm carbon strip in the wings and 2 x 3mm carbon strips in each stab
-stabs angled down by hot glueing a piece of balsa underneath to give the angle.
-All hardware upgraded to Du-bro (2-56 ball links for the elevator, 2-56 quick links for the ailerons)
-Fibreglass nosecone

I had to fly very carefully for the maiden because I was using the stock hardware to hold the wings on and was bit worried that it might not hold up. The maiden was just to prove that it could fly.

Big thanks to Trudge for shooting, editing and posting the video.
