I got this nice MiG-21 as an "airframe only" kit for $249 from MRC :

The original has a length of 14.7m and a wingspan of 7.15m,

https://en.wikipedia.org/wiki/Mikoyan-Gurevich_MiG-21

whereas the model has a length of 173cm and a wingspan of 80cm,

which makes the model a ~1:8.9 scale (almost exactly the same scale as the FW A-4 Skyhawk).

This particular model is suppose to depict the third generation "MF" variant (with enlarged dorsal spine), as described here:

I plan to install my own power setup, an FMS 80mm inrunner fan, as described here:

https://www.rcgroups.com/forums/show...EDF-fan&pp=100

The main reason is that the FMS fan is a lot lighter than the stock (or even non-stock) FW fan plus it has a better inrunner motor.

I have the same setup in the A-4 Skyhawk and it works really were there, no need to change anything

The paint scheme will the Russian aerobatic one, red on top and silver on the bottom. More or less the same scheme I have in my scratch-built MiG-21 105mm edf:

Acquired this new nice small Hawk as a replacement for my 70mm FW F-104 missile ... The 104 flies very nicely but in the silver scheme is a bit hard to see on the landing approach when it comes toward you.

With the idea of moving my power setup from the F-104 tom the Hawk, I got just the $169 airframe ("Arf-Plus") kit :

It is a pity they don't make a similar, no frills & lightweight one, in a bigger size ~90mm

I love the way Hawks fly, this is my ninth edf one from what I can count (the first one was a Gloeckner kit with a Schwerdfeger 69mm fan) ... Too bad the larger FW offerings are either airliners (A-10) or that overcomplex F-14.

It turns out this Hawk also runs rings around my overbelled and overwhistled FW 90mm F-16 even though the latter has a very powerful JetFan / HET 700 combo in it .

I've used gyros for years in my EDF jets ... They can be useful for takeoff and landing, and occasionally in flight when there's a lot of wind.

Without getting into some sort of religious war : I love gyros and use them all the time, under the right conditions (eg crosswind, a lot of wind, some landings etc).

Nevertheless it makes sense (to me) to first get the jet to fly right without a gyro, by

* simple mechanical adjustments

* sensible throws

* correct CG

* correct wing & tail incidences

* correct thrust angle(s)

* correct stance

* sensible main gear position

and later have fun with the gyro on a model that is now at least set up half right Instead of having some chinese mystery electronics just try to fix everything in one swoop. That's at least how I do it.

Here's the gyro in question :

https://www.amazon.com/HOBBYEAGLE-Co.../dp/B0123C57LE

http://www.hobbyeagle.com/gyros/a3super2.php?lang=en

This particular gyro has a number of fancy features, but I only use the most basic ones (KISS principle)

The many options can be confusing, but I use the "NORMAL" mode exclusively, and most of the factory DEFAULT settings. For ex. I never used the "Auto-Balance" , the "3D-AVCS" or the "Auto-Hover" features. I also use the standard (default) setup for servos eg. 50Hz.

As a result, there's hardly anything...Continue Reading

Will install my own 80mm inrunner motor fan with a yep (yge) 150A esc,

https://www.rcgroups.com/forums/show...EDF-fan&pp=100

Was not going to use the outrunner fw fan that comes with the pnp kit, although the performance should be rather similar, at least to the comparable FW inrunner version.

The original Douglas A-4 Skyhawk had a wingspan of 8.38m and an overall length of 12.22m :

https://en.wikipedia.org/wiki/Douglas_A-4_Skyhawk

whereas the model has a wingspan of 940mm and a length of 1430mm, which gives as an overall scale for the model of ~ 1: 8.91 (from the wingspan numbers).

The paint scheme on mine represents an A-4P of the Argentinian air force around ~ 1982 so it's usualy referred to as the "Falklands" ("Malvinas") scheme.

Had no use for the junk fans, junk outrunner motors and escs that the pnp version comes with for an extra $150

The original Sukhoi Su-35 has a wingspan of ~ 15.3 meters and a length of ~ 21.9 meters,

https://en.wikipedia.org/wiki/Sukhoi_Su-35

whereas the model has a wingspan of 108 cm and a length of 163 cm, which gives as an approximate scale ~ 13.8 : 1 .

Some but not all Su-35's have thrust vectoring ... the Su-37 variant does as well.

The original is not a slow floater jet ... Top speed is ~ 2400 km/h or Mach 1.94

Will be repainted in a different camo scheme, similar to the one shown below.

Power will be from twin WeMoTec MiniFan EVO 70mm or a comparable 10-bl setup, with either a HET 2w, Arc or Mad Thrust, or similar , quality in runner motor on 6S.

A proven setup very similar to what I have in my Sukhoi Su-47 Berkut :

I picked up one of these as an "airframe only" from MRC for $159 :

They also sell it (the airframe only but with LG) for $104 in China :

https://www.aliexpress.com/item/RC-a...782118518.html

It seems slightly larger than my JePe F-16 (35" ws vs 31" ws) :

https://www.rcgroups.com/forums/show...by-Jepe&pp=100

so a rough comparison will be interesting.

On this one the wingspan is 88 cm and the length is 131 cm, whereas the real one has a 9.96m wingspan at a 15.06m length

https://en.wikipedia.org/wiki/Genera...ighting_Falcon

so the model is in the ~ 1:11.4 scale range.

I plan to possibly have a tailerons only setup, to reduce wing drag.

Fan will be an 70mm one with quality inrunner, and a 150A YEP esc I already have.

Finish will be in a simple 1984 Belgian TigerMeet scheme, which I have done a few times before ...

http://www.fmsmodel.com/fms-80mm-duc...0-kv2000-motor

http://hobby-paradise.com/en/product...ct_detail.html

For $76 it includes (what looks like) a nice inrunner motor, and that was the main reason for buying it. Many of these chinese fans nowadays include some $10 junk outrunner motor that I really don't care about

I am not familiar with that particular motor brand ("Predator") ... we shall see

So far it seems from the FMS and Bangood sites, there is only one version of this fan with a 3270 2000kv motor.

Different measurements that people might or might not get could depend on a weak battery, incorrect transmitter endpoints, free-standing vs. installed in edf jet, and wrong esc setup (wrong timing not suited to a 4-pole inrunner) etc.

EDIT : Now there is also a softer 1930kv inrunner motor version (see later below).

The manufacturer is listed as "Sky Flight Hobby", and occasionally as LX or Lan Xiang.

The kit version is fine for me, as I really don't need all the extra junk motors, junk fans and junk escs

Will strip out all that thrust vectoring stuff, plastic nozzles, plastic mounts etc as well, and as a result lighten it up as much as possible.

Power setup will the twin WeMoTec Mininfans EVO 70mm on 6S.

http://www.hobby-paradise.com/en/en/...e.html?sort=4d

It is made out of EPO = Expanded Poly Olefin (which is NOT EPS = Expanded Poly Styrene).

It includes pretty much everything except fan and esc (and of course receiver). I really had no need for another $20 outrunner edf plastic fan .

Seems pretty well made for what it costs, the overall near-scale outline and the paint job look pretty good.

More importantly the ducting is actually pretty decent compared to some other FW offerings !

For some reason all the ones I have seen in person crashed badly, nevertheless the F-104 is generally a decent EDF (or turbine) flier.

The original F-104 had an overall length of 16.66m and a wingspan of 6.36m,

https://en.wikipedia.org/wiki/Lockhe...04_Starfighter

whereas the model has 1.403m and 0.656m respectively, giving a scale of 11.88 (length) to 9.70 (wingspan), or on the average ~10.8 scale.

Here's my latest project, I picked this one up at a local HS (Rob's).

Like most Kyosho products it looks very well made

http://www.kyosho.com/eng/products/r...duct_id=109840

The specs are scale 1:7, 1.8m (71") wingspan.

Recommended engine size is described as 90 to 120 ...

(The original F4U Corsair had a wingspan of 41' or 12.5 m, which gives a scale of 12.5/1.8 = 6.94:1 : http://en.wikipedia.org/wiki/Vought_F4U_Corsair )

Here's a direct link to the Kyosho instructions (34 Mb) :

http://www.brentfordrc.co.uk/scripts...idproduct=3337

http://www.miniplanes.fr/avion-rtf/j...r-p-46640.html

On the model the wingspan is 150cm, whereas the original Me-262 had a wingspan of 12.60m (http://en.wikipedia.org/wiki/Messerschmitt_Me_262), so that makes the scale approximately 12.6/1.5 = 7.9:1 .

The next day, Saturday, I flew it with the CG at 115 mm and it flew fine, it barely needed any trims. I use the recommended 4S 4000 setup and it flies well, plenty of speed for a foamie . My latest CG is now at 130mm (see picture below).

My nosegear steering lingage kept getting undone at the field, so I had to put a collar to prevent that Z-bend from slipping out.

The elevator and rudder linkages (pushrods) were really flimsy, I had to make the whole assembly a lot more rigid to avoid a possible catastrophy on the maiden.

Other than that, it flies like a charm
