Hi Ken, the Mig went together quite nicely, but modifications are always needed. Installed electric retracts and much better struts than the ones supplied, they were terrible. I did like the wheels though. I have it ready for an 8 cell setup, so lots of power. Just have to get the servo wires for the ailerons threaded into the fuse. Hoping to give it a maiden this weekend, depending on the weather.

Re: Hobby Topgun Mig-15

Another club member recently completed his HTG Mig15 with an 8S Mercury Alloy fan. He used the stock legs which caused bumpy landings unless landed very slow or in grass. The nose gear length is too long pushing the plane back into the air. He is now going to put different legs on and get the plane to sit in a more level attitude in its wheels. It isn't good to sit very nose high.

Re: Hobby Topgun Mig-15

Well, as we all know, we have good days at the field and we have bad days at the field. Today, I had a very good day. Since I haven't flown since early June, maybe even before that, I parked my ego in the van and allowed my bud, Ted, to maiden the Mig. And maiden it he did, needed some tweeking in the aileron alignment, but other than that, no issues, the takeoff was really smooth, the flying aspects were quite good and the first landing was beautiful. But it's definitely not a speed demon, even with the 2000 watts of power. The jet fan sounded really nice as well.
The inexpensive Hobby King retracts and landing gear stuts worked great as well, all in all, very happy with it.
After adjusting the ailerons, the second flight was even better with a slower approach but attempted a go around, just as he was pulling out, the lipos started to die, so a smooth turn back to the field and a nice landing.
The battery packs were a bit warm, so will cut some cooling holes in the intake duct ahead of the battery position and a good size one aft of the canopy area infont of the fan. Shoukd suck in enough air to cool the area properly.

Re: Hobby Topgun Mig-15

Well darn, on the forth flight for this jet, smoke came out of the tail cone, and alll went quiet. Fortunately, was high enough and going the right direction to make a normal approach, but the slight breeze blew me off the runway and nearly stalled trying to correct, but, landed it did, only a scuff on the nose where it rolled back onto the runway.

Checked everything, the temperature of the motor was 160F. Let it cool down and tested the electronics, the ESC seemed good, but the poor motor just sputtered momentarily.

Of course, the hobby shop here doesn't carry EDF motors, so having my son bring me two fresh Mega's when he comes here on the 24th. Thought I had brought a spare, nope, oops.

So, will have to get my other two EDF's ready now.

Oh, the model itself is very nice to fly, takeoffs are very smooth and scale like, steady in flight, will do a loop from level flight, and landing characteristics are what we all hope for. It's really a shame they discontinued the model instead of addressing the issues.

Re: Hobby Topgun Mig-15

My son arrived today via Air Canada, brought me two new Mega's and two new Hoaye EDF units. Will get them setup and installed in the Mig. The JetFan sounds really nice and very smooth running, but the Hoaye outperforms it on a seven cell setup. I'll still use the eight cell as the model balances well with those batteries, but will adjust the throttle settings so it will not exceed the 90 amp maxium.
