I have a evolution .52 nx I might try tomorrow. because i flew it with the .46 la and it sucked. If that doesnt work. ill put the .52 in my decathlon and put the decathlon's .61 fx in it. if i thought i was going have to buy a large four stroke i would have bought the 60 sized arf. guess i should do my research before i buy
YEah - heres the weird thing - there isn't a lot of size difference between the UCD 46 and the 60 - I mean there is, but if you put them side by side, you'd think the same thing. The UCD 46 seems like a bigger plane to me than other 40 sized 3D planes. Lots of Wing. I have the 60 with a Saito 100, running a 15x4W APC prop and 20% Cool power - it takes off in about 20 feet of roll and will pull vertical until it's a little dot in the sky. It weighs about 7.3lb RTF - thats running a cowl, wheelpants and a spinner. Mix in flaperon/spoileron and it is plenty of fun.
If you put the 61fx in your 46, heres the cool thing - a saito 100 will drop right in with no changes to the motor mount - there's less than 1/16" difference in the prop hub location, and the motor mount bolts pretty much line right up. other than having to change your throttle linkage, and maybe needle valve hole in your cowl, running a 61FX is basically an easy way to step up to a 100 in the future.
