Just curious what your altitude is where you are flying in Mexico?

Hello

I have got one kit of HSD F16 1800 MM foam.

please advise if I can use K85-G2 KINGTECH turbin engine or not? is it too heavy? how to adjust gravity balance?

Hi
The K85 has the same weight of the K60 therefore no change in CG. However the 85 will burn more fuel than the 60 and you should definitely be cautious and use wise throttle management in order not to over stress the F16 beyond its limits

Well we would, but it is kinda hard to take you seriously after you conveniently left out the 100 class turbine part while bashing a company. Sooooooooo

I think top end on the K85 is too powerful for level flight, & not sure how the residual thrust will affect your landing speed although I think that the 16 will slow just fine. I can say that the HSD 16 does very nice high alpha flight, but with my K-60 Ive had some hairy moments transitioning back to forward flight at low altitudes. I will probably upgrade my P-60 in the future, but I already have my timer set to 3:30. I moved it up to 4min, but had no reserves for go arounds.

Does anyone know where I can get a 2000cc fuel tank for the F-16?
The tank in the plane is only 1400cc and does not provide a long enough flight time for me.

Thx in advance.

Nice! Did it require a lot of material removal or modifications to get it to fit?

No removal, perfect fit. Had to epoxy the strap to the foam on the bottom - the lower neck on the bottle is perfect for the strap to hold the tank firmly in place.

I had to buy a bottle cap vent and fuel line attachment (Chief Aircraft) and quite surprisingly, it all came together with little effort. I made sure that I got the tank as close to the turbine as possible so that there would be minimal CG shift as fuel is burned off. My CG is around 175, far forward of the manual. I always measure CG in the landing configuration, landing gear down, header tank full, main tank empty.

I hit 145 mph on the telemetry GPS (tiny headwind) in a straight line at about 5/8 throttle. I am sure that if I pushed it at full throttle for a longer period, I would have confetti on my hands. A straight up line was just awesome and never ending. Power to weight is above 1.

The K85 (G2) is about the same size as the old K60 and it weighs about the same. I needed no weight in the nose; using a 2200 3S Lipo, 1300 3S Lipo, and a 2100 3S LiFe (turbine), upfront, brought the CG to where I wanted.

Thanks for the info. May have to look into that after I maiden mine.

Sharam,

Very useful info. Thanks for sharing. Did you notice any particular drawback from the added fuel weight on take off and during first couple of minutes into the flight? are you able to land the F-16 slow?

Thanks
Regards,

Hi Guys,

I read about your modifications and want to throw my .02 in. This jet was designed around a 60N turbine or 12 lbs of thrust. You are now putting almost 60% more thrust in this jet with a K85 at 19lbs. If you want to increase the weight, wing loading and thrust, I strongly suggest changing all the Servo's. control rods, control horns and servo arms to a good heavy duty product. The servo's and hardware that comes with the jet is not the highest quality. The plastic servo arms and control horns are very brittle and breaks very easy under high stress. With the added weight, thrust, speed and flying forces, you will have a failure if you don't make other changes!! Trust me, I am all about having fun, but spend the extra time, effort and some money and change out all the hardware and servo's to give yourself a 1/2 of chance to get more than a few flights before it turns itself into coffee cups.

If you want to save yourself some heart ache, T-One has a 1.8M, Full Composite/Carbon Fiber F-16 coming out in a month or so. There are no control horns or control rods on any of the surfaces to deal with, as they built this like the 1/5 F-16 Big brother and has direct drive servo arm to control surfaces. This plane is designed for the 70-85N turbine but it has been tested with a 100N turbine to the most extreme flying to fully test its strength and durability. It has Electric retracts standard, light kit available as well as a PNP version. We will have pricing and more details out very soon.

Be Safe guys!!

The PowerHD servos, if they are still using the same ones, will be fine.

Hi All,

Been a while since I posted here. Asked this question over at RCGroups and haven't had too much feedback, save for one comment.

Does anyone know of any failures that have occurred, or any quality issues with the thrust pipes that are used in the HSD turbine F-16?

Busy converting a Yellow Aircraft F-16 to turbine power with a K-85 turbine and I'm looking for a pipe. Given that these jets are almost exactly the same size, this pipe should suit my needs. Any opinions appreciated, thanks.

Cheers,

Hello All,
Although Pacific RC Jets no longer carries HSD products, They are available at www.HSDGO.com (HSD Jets)and www.bananahobby.com. Video is of my 111 flight of my KingTech K-60G2 powered Super Viper V3 in the T-45 paint scheme.


Cheers!

I am looking a getting one of these. Have you been happy with it? Would you buy another one today?

Desert Fox 1

jet-lover,
I have been very happy with my purchase. The Super Viper is a good first turbine aircraft. I have over 111 flights, with no real issues, yes I would buy another. I do not use the smoke system. I have plumb the to tanks together and have my timer set for seven minutes. I usually land with the main tank more than half full at seven minutes of flying. Top speed is in the 135-145 mph straight and level and 155-185 mph on gentle pull out of dives. These are from my telemetry readings. I got my turbine waiver with this bird. I am fly without the gyro turned on and find the aircraft stable and locked in. Unless you can find a sweet used deal, this is great way to get started in turbines. I fly at a very active club "Georgia Jets". Numerous members have commented on how well this aircraft performs. My RC aircraft YouTube channel https://www.youtube.com/user/rmshump..._as=subscriber

Im putting one together with a KINGTECH 85 G4. Dirk said 1". I am going to verify. Can someone post pics of the installation if the pump, ECU, RX placement? I would appreciate that.

3/4" from the end of the pipe to the tailcone of the turbine is standard for turbines
