This jet just got maidened this weekend! It flew real nice....needs lots of exponential on the ailerons :0 to keep it flying smooth. The CG on these HET F-20's is really hard to get right. I have my batteries pushed all the way back in the battery compartment and it is still nose heavy. I have now moved the EDF unit back 1/2 in., so that should help get a little more weight towards the back. We will see how it flies with these changes next time.

It uses my standard 1100 watt minifan combination and has an AUW of 48.5 ounces.

Not as fast as my Yak-23, but it looks beautiful in the air. With the F-20's lines, it just looks wicked.......

I wanted to try a close to "scale" A-4, so when GWS came out with their new TJ-4 airframe, I knew it was the perfect base to kit bash an Israeli Air Force A-4H.

It was a huge project and was a lot of work, but I am very satisfied with how it turned out. I flew it for a bit and now have the airframe up for sale if anyone is interested

I also used this project as my first official "build-thread" here on RC Groups. It was a lot of fun getting everyone's feedback as the project progressed.

Here is a link to the build thread:

I originally got this as my first EDF. I figured the straight wing would be good to learn on. Well, as it was my first all balsa kit build, it took a LONG time for me to complete and the craftsmanship could be a bit better. But, it finally came together several months ago and....

The results were stellar, this jet is fast, smooth as silk in the air and is very uncommon. There is a very good chance that you won't ever see another one of these at your flying field

The current hardware I use in this jet is a Minifan, 7S 2100mah pack, ARC 28-47-2 motor, Suppo 70 amp ESC. 1100 watts and about 57 oz. of thrust at 80% FSA.

AUW is 50.5 ounces.....

This is currently my most flown plane in the fleet....

Not wanting to give up, I took the delta jet's wings and promptly cut them off I purchased the Profili2 airfoil software and learned how to build a "real" wing.

I picked out an SD6060 aifoil, cut out the ribs, spars, etc. and made a nice straight 48" wing. I then morphed this wing on to the delta's airframe and made a tail section for it. Also had to lengthen the nose a bit to get the CG correct.

It flew great! Had a slight twist to the wing, so at high speeds I had to give it a little bit of aileron to compensate, but other than that, WOW, this thing just floated along with very little power required.

It was recently decommissioned and just sits on the shelf....I may take the wing and make a slowflyer out of it someday......

I wanted to try my hand at scratch-building something. Deltas seemed simple enough, so I went to the local hobby store, bought some depron sheets and went at it.....

Bottom flew like crap It didn't really have an airfoil to speak of and it showed. Unless I was zipping around at 50mph, the thing would just go into a high-alfa and crawl around.

One day while trying to sort it out, it went into an unrecoverable flat-spin.

It went into the corner of the shop.....for a while.....

This was one of those projects that teaches you more about what not to do than what to do

I really wanted to try a full-house plane with a rudder, so I got this WattAge P-47. I transfered all the hardware from the FW-190 over to this bird and it still flys to this day. It's another sweetheart of a flyer....looks fantastic in the air!

Runway long knife edges are not a problem with this overpowered plane

I thought EDF's looked and sounded really cool, so I modified a cheap Stryker airframe to fit a Wemotec Minifan. These Strykers really fly nice, no matter what you put into them.

I had so many different combinations of motors and ESC's on this thing that I won't bore you with the details......but, the final powerplant this "jet" had that you see in the pics is a 720 watt combination consisting of a 6S, 2100mah pack, ARC 28-47-2 motor and Suppo 70amp ESC; servos were HS-81MG.

It flew great to the end, but I just got bored with it and moved on to other airframes.....

I am an avid WW2 buff, so this RTF plane from Parkzone was a natural for my second plane. I felt like it would be the perfect first aileron plane for me.

Once I got it up in the air, I could not believe how great it flew. At this point I knew I was hooked on the hobby. I invested in a Spektrum DX-6 radio and converted the whole plane over to good electronics. I ended up putting in a Hacker A30-16M brushless motor, 2100mah lipo, and propped it up to 350 watts. At 28.5 ounces, this thing was a real rocket! After flying it for well over a year, the foam fuselage finally started to get a bit rough and I retired the 'Butcher Bird" from the fleet.....with many fond memories!

Well, this was the plane that started the addiction for me! I had done RC cars and boats when I was in my teens, and after selling my full-size drag car, I was in need of an affordable new hobby.

I got this Sky Fly RTF for $99.00 shipped. It taught me the basics of flight....boy, I thought this thing really flew good. Well, ignorance is bliss, because I now know how bad most of these RTF planes fly....but hey, if you can fly one of these, you can fly anything
