No issues. or concerns The F16 is nicely linear in pitch and roll at full power with the K60. Nicely balanced powerplant combination IMO It gets in a groove and is just plain fun to fly. I have flown it from field elevations of between 1600 -2300 msl.

Okay, let's leave out the stab issue:
The F-16 flew great but was plagued with gear door sequencing issues and glue adhesion issues, most notably also in the landing gear area.

Glue adhesion issues with the 100 class turbine in it*

luge_racer

Fine. How about: all HSD jets I've owned regardless of the power plant; whether turbine or EDF, stock or upgraded, have had glue adhesion and landing gear issues.

Are we talking about the latest version here or anchient history. I have the latest version of the Super Viper and there are none of the issues you describe but maybe I just got a good one.

We have the f16 in our club with the k60 for power, good flyer. Only issue I see is the Chinese need to use better material for making plastic linkage parts and servo arms.

Hi guys, I recently just got my hands on a HSD F-16 and noticed that one of the fan blades was damaged. I wanted to remove the unit but not sure how you go about it. Anyone take one out? This is the electric 105mm fan version.

Are you on RcGroups? If you don't get an answer here in the turbine-jet forum, you should try the gurus over there in their electric-jet forum. Super knowledgeable EDF guys over there, & already a thread dedicated to the EDF HSD F-16.
Good luck! Jay

My friend just maiden his F16 with the recommended CG and it was a unflyable and ended up on a tree.
I also have 1 but my CG is forward of the recommended. Not sure how much. I have all 3 batteries as far as it can go, plus a few more ounces of weight in the nose cone. Mine flying good.

What was his recommend CG? It seems as though the earlier ones were way off and the lastest ones are better? I haven't flew mine yet maybe tomorrow,but it has orange cg stickers on bottom of wings at 178mm

Flew it at 185mm, no issues

well i have and f16 with k60 turbine and just dont see the perfomance that i have see on other similar videos, i fly at wot and i really see that its not flying to fast, i cant make a vertical because it has not power to make it, i thought open a hole in the turbine door to get more air and nothing happend fly like under power.

need some adviced plz thanks.

video f16 wot

What is the spacing between the tail cone of the turbine and the beginning of the pipe? Not the bell mouth. it should be about (Correction 3/4) inch from where the pipe starts.
If the spacing is wrong it could cause some performance issues. It looked like it was flying good, You have to keep the energy up to get a good vertical climb. This jet will not climb out of sight, like other jets lt will have its limitations.

Hope this helps..

oukenfold

do you think this can affect the speed of the jet?

It looked like it was flying OK to me. I'm not sure I'd want a foam jet to go much faster...

I did not see any verticals in the video, but it looked to me, based on the speed it was flying, that the speed and power would be good enough to get +500 feet on a vertical climb.

How much does the jet weigh full of fuel?

Bob

Digital Pilot

Use a tape measure and check. Looks to be a little far away to me but need to measure to be accurate.

rhklenke

My Feedback: (24)

It looks to me that the spacing is about right, but the bell mouth is small, so it probably wouldn't hurt to have the turbine a bit further forward - leaving a bigger gap.

Yes, this can affect top-end speed. The turbine doesn't consume all of the ram air coming in the typical model jet intake, so it needs someplace to go out of the fuselage. Having enough gap there allows some of it to be pulled out by the turbine exhaust - with the added benefit of keeping the pipe and engine cooler. If that ram air coming into the intake doesn't have any place to exit, it backs up and causes extra drag which slows top-end speed...

Really, I wasn't aware that being too far away (within obvious limits) can effect dynamic thrust. Most installations that I have seen that have issues have been with too small a gap, not with too large. If anything, it looks to me that the bellmouth size vs. the engine and tailcone diameter is too small, leaving not enough area for the ram air to exit.

I have seen this video and my f16 it's half that speed at full throttle

Digital Pilot

I would not move it forward, There is a major safety issue with engines being to far away and getting a bad venturi effect that can cause a fire.
I would stick to the 3/4 inch. It honestly looked pretty proper on performance. Have you checked to se if you are getting max RPM on the engine? Maybe try to re-learn RC with Half Expo

Digital Pilot

Have a look at part one of this guys video, at about 9:00 he explains about the turbine placement and that it need to move back from what the factory says.. Dirk actually says 3/4 on the spacing.

causeitflies

I think the wider angle of the camera lens makes it appear faster.

Great News!!!

Kingtech EPO V3 Vipers and F-16 Jets are back in stock and ready to ship from the factory. There has been some questions about getting spare parts and the good news is Pacific RC Jets has most landing gear parts, electronics controller boards and some V3 airframe parts in stock at the California warehouse. Please contact Dirk to order the parts you need.

FYI, There is only 1 (Special Price Gray Eagle F-16) left in stock at the California warehouse with FREE SHIPPING in the US!!!

Happy flying

I finally maidened my F-16 (with ACE 60). I was pleasantly surprised at how well it flew (CG at 178mm, no gyro, stock throws except 15mm on ailerons). It tracks really well and is very predictable during landing. I have 5 flights on it and fly WOT 90% of the time. It's not real fast but it's fast enough. My biggest complaint is the short flight time, around 4 1/2 minutes.
