I was at the hobby shop today and I could not believe what I saw... a hobby lobby F16 canopy on the counter. I said to the customer, "is that a hobby lobby F16"? He said yup. LOL. He needed parts to yank all the cheap clevis', etc. too. Just what I was there doing.

I also grabbed (2) 18" servo extender cables (a little heavier duty, but not much heavier), so I can get rid of Y, use servo sub-trim to adjust elevons, and use aileron differential should the need arise. Unfortunately, I'll have to leave the Y in place for the elvator. But that's ok. I also bought a 6" Y so I can add another server, should I continue to have a problem syncing up the steering nose gear with the rudder. The 3' cable from nose to tail is too flexible and does not hold a setting. I'll use standard micro servo and dubro servo ez links to hold the cable in place.

I also picked up 2/56 linkages, clevis', etc. A little thicker than I wanted (2mm would be better, but typical hobby shop didn't carry matching clevis' to their own rods). :-) I also bought new landing gear wheels all around. The foam ones get a soft spot very quickly sitting out on the field. At home, I rack it off of its wheels, but they quickly flatten on the ground. The are the lightweight wheels, but still a little heavier than stock. That's ok. The stock one for nose was missing parts anyway. I also got some matching paint for nicks as they happen. I'll post results of paint colors from LHS, once I know they match. I also got replacement control horns from dubro. They are about 1/8" taller, but I'll just clip them shorter. I don't need the extra hole for more throw as it's already got about an 1" throw.
I also picked up a prop balancer because I have a feeling it's way off balance based upon wear of inner shroud...out of the box.

Pete,

Just so I don't damage the fan, where do you hold onto while unscrewing the big bolt of the fan unit?

Thanks,
Michael

mjbennett9 · Sep 24, 2008, 02:05 PM

Did anyone else notice that manufacturer installed ferrite noise suppressor on power leads from ESC, versus the usual ch3 throttle connection? Odd. See my pic from previous post.

AtTheMet · Sep 24, 2008, 03:31 PM

Michael,

Just reach in with your fingers and hold the fan while removing the outer screw and the adapter nut. Safer than running a screwdriver or something in there which may bend a fan blade.

And yeah, I noticed the ferrite ring. They know they have some interference issues.

2.4 Ghz the only way to fly.

Oh, if you get any bings and bongs in the foam, the light-weight 'pink' spackling paste can be smoothed into a dent and then painted with acrylic poster paint from any craft store. I bought a bottle of white and black and mix them to the color of gray I want. It dries flat and looks like what's already on the plane.

Dang,It almost seems like this jet was made in two different places.The fit and function on mine was great.The only real problem was my fan was unbalanced,and shows alot of wear right out of the fuse.I purchased the upgrade setup so I was not that concerned about that.I posted some videos in the foam jet threads,it flies great.They did miss the CG location by about 25mm,but It would fly were they state it to be,its just real nose heavy.As far as a flimsy nose cone....whats the problem there?I have been hand throwing mine,no landing gear,and not so much as a scratch in 12 flights on it so far.I would suggest not to land it on its nose anyways...

I doubt this is called a begginner jet,so I hope new people to jets do not try and make this there first one.I do not beleive I even looked at instructions,except to check the CG...and I did not really need that info anyways....lol
Its a really nice flier,and everybody and myself loved the way it flew and looks on low passes right off the deck.Not a bad job at all on this jet HL! Joe

Okay, so now I feel better knowing that it's not only me having the power/glitch issue. Too bad I wrecked a hot looking F5 CAMO version before finding this thread

With my 2nd F16 (1st was received crushed beyond recognition) and promptly replaced by HL. I won't attempt a maiden flight until I can rectify this glitching issue. I went as far as buying another recvr (spektrum 500 full range sport) with the same results. During 1/2 thru full throttle I get pwr glitching when I try any elevator/aileron movements. Tried swapping receivers (2 6100's and the 500) with the same results, yet they all work in my T28 Trojan just fine. So I guess I'll try the aluminum filtering 1st, then try swapping out the ESC. I just hate to add more money to this project but it has so much potential. Take note that this was also the same experience I had with the HL 70mm EDF F5 obviously they use the same hdwr. Anyway, thanks for the postings and I'll surely post my results.

Hey DB4.... I had the same experience with an F16, fried ESC during pwr up testing. What do you know the wires from the ESC to the motor each had enough of their brass connectors just staring me in the eyes all crimped to the same lenghts and within cm's of each other. Just the right situation for an arc to occur Surely we should not be seeing any of the brass fittings on any signal/pwr connections A bit of electrical tape or longer shrink wrapping would've easily prevented this. No doubt my F5 and F16 EDF experiences will never be forgotten.

mjbennett9 · Sep 25, 2008, 08:16 AM

I tried the ESC in another plane with two hitec servos. Same glitching. Even at 1/4 to 1/2 throttle I saw bad things. While the throttle didn't cut out on its own until full throttle, it did cut out at low throttle with slightest servo movement. It's either the separate BEC, and/or the ESC. Not good. I even tried it on a 3cell thinking the chinese BEC could not handle current with a 4 cell. Same thing though.

mjbennett9 · Sep 25, 2008, 08:31 AM

Note. The aluminum filtering I ordered, while it may work, is not as pliable as the website states. Very fragile and and not workable like aluminum foil. I would not recommend buying it. I'll stick to good receiver and replacing the cheap ESC.

mjbennett9 · Sep 25, 2008, 09:00 AM

I've been reading the other post at http://www.rcgroups.com/forums/showt...895716&page=16 and it seems the CG is WAY off. I figured as much because my first flight took forever to rotate off the runway.

Well, well, well, after pondering this issue overnight (on the job) I got home this morning and covered all the wires in the duct vent area with foil and it did reduce the glitching (reduced not resolved). Prior to replacing the speed controller, I opted to try my old FM stuff (JR6102/Micro Recvr) vs the DX7 which works fine with my Heli's and other planes by the way. What do you know the glitching is gone!!!. I'll maiden it in a few with FM (didn't want to go backwards in time/technology). This I'll try temporarily until I come across a setup where I can just add this and my F5 to the list of models in my DX7 setup. I'm sure they've sold hundreds of these and I read about those that are working with spectrum??? I just don't wanna have to upgrade all of the electronics to do so. If that's the case I surely would have purchased a non ARF build it yourself kit.

AtTheMet · Sep 25, 2008, 10:56 AM

Philld,

Interesting that the FM works with the factory ESC. The ferrite ring should have been a giveaway. I never tried that since I use DX6i. After eliminating all other possibilities with the glitch, I just replaced the ESC and it now works great

After several flights, I noticed one of me elevator linkages was actually BENT (cheap and too small wire rod and clevis). Won't happen now
