WOW fantastique 🤩🤩🤩

[@xKmotx]

What a lovely engine!

[@rperry70]

I Purchased one of these and plan to run it soon for the 1st time. What are the optimum props for this engine? I have a scale Axial 28x10, but realize I may need to go a little smaller.

[@stclairjm]

From what I've read that's about what size they recommend. Results in a little more than 5k rpm.

Do these come with the fuel pump? If not do they need the fuel pump to operate properly?

[@173shatta]

jasonjanise yes all the UMS engines comes with our pump system
