I still stick to the ums 160cc. I just wondering what is the different if I choose ums 180cc but flying with same prop size as ums 160cc. Lets say both engine has the same weight.. Will the 180cc fly faster than the 160cc with the same prop size?

That’s all 1/4-1/2 throttle in the video

Congrats for the award.. The plane took off at slow speed without stall.. The torque should be really high at that speed.i just waiting to see the plane fly at full throttle hahaha. I'll be getting my la7 next week. 1st step to strengthen the fuselage with cfk

Congrats on the win.. The plane looks great.. My buddy has put his 160 in a Jerry Bates Claude.. Says its starts right up and has no issues..

thanks for the comments guys...this engine has been solid, just need to stay on the valve clearance 😃

James... What is the total weight of your plane right now? I done some reinforcement on the fuselage using cfk and epoxy resin making the plane slightly heavy.i havent get 7-160 ums yet. Wondering if the power is enough to make the plane climb up. Or I might need to get the ums 5-180 or 5-210.Need your advice

that’s the UMS 5-180. It will fit the cowl better making an easier build. The 7-160 runs great and pulls loops at 1/2 throttle

n8622t 07-28-2019 07:03 PM

Weight is 44 lbs

yeah it’s going in a TopRcModels FW190

You must be a fan of UMS.. Instead of Moki 😍. Running those engines with pump?

n8622t 07-29-2019 06:42 AM

I have Mokis too and the UMS engines don’t need a pump

I might go to Ankeny, still haven't decided. Only a couple hours drive for me. If I go, I plan on taking my LA-7 as well.
