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?

Just received my electron retract and robart tail retract for cy la7. Will try open new build forum for this

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..

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

You must be a fan of UMS.. Instead of Moki 😍. Running those engines with pump?
|
I have Mokis too and the UMS engines don’t need a pump |
La-7 getting a look over before heading to Ankeny Iowa Airshow https://cimg4.ibsrv.net/gimg/www.rcu...fcb5e8749.jpeghttps://cimg3.ibsrv.net/gimg/www.rcu...69ed81f11.jpeg https://cimg5.ibsrv.net/gimg/www.rcu...a0a6c2fa6.jpeg |
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.
