Official Freewing MiG-29 Fulcrum Twin 80mm Thread

Yep, each and every one of them :)

Plus, installing FMS Pro 1900kv EDFs with 80A Hobbywing Skywalker or Premium ESCs.
And if you need a sturdier main LG, the Freewing F-15 mains seem to be a good alternative, judging by other people's experience.

Airguardian , I remember seeing an outstanding video you did some time ago when you first got the SU-35 with all the mods and reinforcements you did. At the time, it actually made me think twice about getting it only because you did quite a bit of work to it and I was (probably still am) a bit lazy. But now it's back at the top of my list for the next EDF after watching so many of your great videos on it! Assume you still recommend all the changes you made?

Contrary to popular believe, EPS is superior to EPO from a material's structural properties point of view. EPS can achieve the same rigidity with thinner walls which makes it much lighter in the end. This is one of the biggest reasons why the FW Su-35 pretty much kicks any other scale EDF jet in the market. (The other being that the Sukhoi design is godlike, ofc). ^^

If it was up to me, I'd have Freewing make all their jets with EPS and ditch EPO. Sadly, I'm told that, weird as it may seem, EPS is hard to source in China, so this increases production costs. Availability also seems to be limited so they save it for the Su-35. All other EPS models in Freewing have been discontinued but the Su-35 is still a bestseller as far as I can tell... after some 11 years or so since its introduction, it is still pretty much the top tier EDF. That should settle your mind about it. ;)



It is definitely slightly more fragile if it comes to the point of crashing, but you should try and not crash in the first place!
As Evan said, it often breaks clean which makes repairs easier. And EPS can be glued much easier than EPO. Epoxi and contact glues work wonders on it (where Epoxi fails miserably on EPO, by comparison). Foamtac... haven't tested on EPS but should be fine, same as Gorilla Glue. UHU POR is a good option for large broken chunks too as far as you have large surface areas to make contact between the pieces.

So indeed, there is a lot of difference between the two materials and I prefer EPS.
True that EPS gets dinged and scratched more easily too, but I choose performance over looks in this case. And if you treat the plane with some caution it ain't even that bad. ;)



What, why?
I have done it.
It gators badly, true that... but you can easily use light spackle and sand it afterwards.

thanks as always. su35 back on my radar...

AG, reading some of the reviews of the SU35 i became a little bit turned off on it. I read where it's made from EPS foam and not EPO and that it was much lighter (and therefore, more fragile?) than what an EPO foam version would be like.

Being that i tend to break things off of these from time to time, i'm wondering if that also means it can't be mended with foam-tac adhesive...
in any case, do you have any thoughts on whether or not there's much difference in the two materials...?
I may be giving myself paralysis from over-analysis, but I just like to know as much as I can before I jump...

It can't be boiled back in shape.

I like the EPS foam. It holds its shape better and is easier to repair than EPO. Just don't use an adhesive or paint with organic solvents.

My SU35 and Eurofighter are each 5 years old and look better than any of my EPO models of the same age. And they are LIGHT!

[Evan D]

I like the foam the SU has, it breaks clean so you can glue it back easier. It can't be boiled back in shape. I use gorrilla glue to glue it instead od the usual EPO glues.

[jasmith41]

Yes. :)

Old flights that I forgot to post...

[Airguardian]

Yes. :)

More pre-crash, no VT:

6s and stock fans?

[Airguardian]

Indeed, so much more stable and predictable with the stabs getting clean airflow! :p

I think I have another couple of un-vectored videos to go (not counting pending air to air stuff that god knows when I'll find time to edit) and then it's vectored videos only going forward ;)

[GliderGuy]

Interesting how the inverted high alpha characteristics differ considerably from the non-inverted characteristics.

Anxiously awaiting your first VT video post.

[Airguardian]

Thanks!
Pre-crash period still.
I swear you will KNOW when the video features the jet with the VT installed ^^

[GliderGuy]

Post repair + VT added or is this video some pre crash period?

Enjoyed it regardless. You are always adding to your maneuver suite.

[Airguardian]

Only without TV nozzles ;)

[radfordc]

This plane is like a high strung pony...fun to ride until it turns around and bites you in the butt!

[Airguardian]

Thanks GG!
I didn't catch it on video this time but essentially another episode of bad-thrustline messing it all up.
I was performing a kulbit and started at too low altitude. I didn't come out clean and immediately entered a high alpha lock. Had only some 15-20m clearance and it wasn't enough to pull out so I pancaked straight to the ground. Fuselage cracked in half in two spots, ducts slightly crushed and broken (nothing too bad), nozzles came out and a few other areas in the fuselage got cracks. Most of those have been fixed already, I'm waiting for the glue to dry and I'll start re-installing the ducts and adding the TV nozzles.
