Default Red Square Models - Mig 3

I should stay away from Model Shops ........ had to drive to Riga yesterday and thought I'd drop into the only real model shop we have in Latvia.

Came out with this kit : (built her last night - just need to fit canopy and radio gear) ....









Just over 1m span, touch over 1kg AUW, 3836 1000Kv motor I fitted and 10x6 prop with 11x5.5 back-up. Spec'd for 3S 2100 LiPo

Choice was military version or the Soviet Sport version I went for ....
GRP fuselage, wood / film wings, wood tailplane. Not a bit of foam anywhere ....

Having a strange problem with it ... and not even got to fly yet !

The control horns are so brittle !! Slight knock when moving and that's another snapped of. Have to raid my box and find some more durable jobs.

Shop reckoned all servos on it to be 9gr size ..... well ailerons were a very tight squeeze and mounts needed opening out.
Main elevator / rudder mount plate in fuselage is for much bigger possibly 12 - 17gr size. To be honest with a model of well over 1kg - the servos I reckon should be in the larger mini size. Ailerons OK as they are 'powered' separately .....

This is one modeel I will not be pushing limits on ... as I reckon she will fly nice on that 3836 motor and a 3S ... there's plenty of grunt in it to take the 11x5.5 if needed.

Very nice. I'm a Mig fan, from that Mig-3 all the way to the -31! Let us know how she flies. Looks like she's short-coupled between the wing and h-stab.

Thanks for sharing!

Yep that's a short moment from wing to stab .... so care in setting throws I reckon. The manual gives figures - so will try those and see how she is.

Having watched another fly - she's quick and steady ...... but of course it all depends on each persons set-up.

She flies a dream but keep speed up on landing and greaseeeee her in ....

The U/C mounts though are not so strong - but that's better to rip the leg and small block out than shred the wing by a stronger mount.

It's a relatively heavy model on a tapered wing ... so care to not slow her too much and incur the dreaded tip-stall.


At the end when I land ... I forget the camber and rise of tarmac !!

I have a set of servo-less retracts and considering whether to modify to fit them .....

Sounds like she could use a split flap under that centre section while you're doing the gear mod.
I never like to see fixed gear on a WW2 warbird - and flaps would give the ability to slow down for your landings... but up goes the weight again!

Long time since I bought this model ... nearly 8 years !!

For last few years - its sat looking sad having had another of its crashes.


It really is an unforgiving model ... she will snap as quick as anything and no way to get her back.

Guy on RCG has just 3D printed a Mig 3 and its re-kindled my interest ... the wing looked so bad - even I had my doubts .. I'd removed the retracts to fit to my Mossie (that's crashed due to my flying longer than batterys could !) so I may put them back.

The wing actually is going back together without too much trouble ...

As you saw in end of video - that wing was smashed ! The magic of CA and then backing up with PU glue to create fill-in has restored that rear edge ready to have some strip sheeting applied from my scrap box ...





The fuselage is mostly in good condition - only the nose section took the major impact with that right wing. CA and again PU glue to get it back into shape ... then resin filler to fill and strengthen the ruts and holes ...











Then once all done ... she'll be ready for her next crash !!

Gotta keep busy for sure. It's great to see you're bringing this plane back.

That nose is pretty banged up and out of shape ... wing is near finished structurally ... just needs laminate another set of thin ribs to the ones I spliced in. Originals were lite ply - but because of need to shape etc - I used balsa ... now I will give another balsa rib alongside with Epoxy - that will create a strong rib ...

The nose is tacked with CA at moment and held with tape ...glass fibre work on inside to reform and hold ... then remove tape ... car filler on outside to try and get some cosmetic improvement / fill the cracks etc.

Still haven't decided on refitting retracts or not ...

I tacked this cowl back together and then used a light fiberglass on the inside. My friend tried to plant an Extreme Flight 48" laser at a 45 degree angle full throttle.
The spray paint I found at the hardware store matched better than new.

Make the photos smaller is what security token means. They never did fix the photo issues.

Bought back memories. I actually have a plastic model of that plane. I think it is a great looking beast. I like the silver nose. Must buy a big one one day.
