Hi all
got a WM GS Spitfire with a MoKi 2.1 ready for take-off.
Any experiance / tips / issues with that plane would be welcome.

I have the WM GS mustang with a Moki 210, probally pretty similar performace. This will be my season # 3 with the plane. I have found the APC 18x12 prop to be the best combo for my mustang, lots of speed and great thrust. One warning, If you are flying on a calm day I would suggest landing with flaps and dail in about 6% down elevator with them, my first landing was without flaps and the mustang did a sudden snap about 1 ft off of the ground without warning at all, since then I have always used flaps for landings and have not had the plane snap on me again. Other than that if you fly off of a grass runway you may want to hold down a little more up elevator than normal, seems mine will like to tip over in the grass fairly easily with the stock gear, sometimes it seems that it lifts off a little too early while holding in the down elevator but the moki has enough power to overcome an underspeed takeoff.
Best of Luck let us know how it comes out.

Thanks Michael
I have a Master Airscrew 18x8 on mine right now. You think it will generate enough trust and speed ? The plane is approx. 14 lbs.

The master airscrew is NOT big enough for the Moki 210, it will cause it to over-rev and will possibly damage the engine. If you can't get a hold of an 18x12 try a 20x10, 20x8, or a 22x6 maybe a 22x8. But for sure not the 18x8 it will definately lead to problems. Let me know what happens.
