ksol-Alpha Mig-15

I am starting an Alpha Mig-15. Has anyone built this model? Any suggestions will be appreciated.

Make sure you scrape off all the paint in the wing root area on the fuse for the glue to hold. The stab incidence is negative, resulting in built in up elevator. Fudge the leading edge of the stab up about 1/16in. and you wont need any elevator trim. I used the Himax 2015-5400 with a Tanic 2150 3s and CC25. Flies great and takes off of the ground easily.

Thanks for the info I will follow your suggestions. Do you take off from grass or a paved runway?

I have one suggestion and that would be to glass the fuselage...these things are a hollow shell and no matter how careful you may be, it's going to go soft and mushy in no time. Using .5oz glass and thinned Zpoxy resin will not add any appreciable weight. They fly great but IMHO the price for the convenience in building is not worth it based on the lifespan of these things. Same for the TU-183 as well. OF course, this is MHO.

That is interesting. Do you use a brush for application?

ksol,

If you're not familiar with fiberglassing techniques I'd get some help or let it go. Even reading instructions for the first time would best be practiced on a junker (there are instructions for glassing all over the web), not a nice new plane like your MIG.

ok I will do that.

Do you glass the inside , if so where.........
On the outside I guess along the bottom from the nose to the fuzz join over the plastic insert :confused:

I have used a water based polycrylic spray (Minwax Polycrylic clear gloss protective spray). It does not eat the foam and gives protection .
Seems to work pretty good and it is clear and does not affect the aluminum color.

ken one more thing reinforce the wings where the wings join the fuselage , by the way i added two hitec 55 servos for the aillerons one for each side , thats just me you can get away with one servo but i prefferd two
