I am on a very limited budget and have a UCD 60 and am looking for a low cost, good performing motor for it.

I have narrowed it down to the Magnum 91 or 108. They are both priced the same at $150.
I would love to put a Saito 100 or something of the sort but, being on a tight budget, simply cannot do it.

I have read all the threads on the UCD but found very few using either of these motors.

Both of these Magnums are priced right. Surprisingly, the 108 has a published weight of less than the 91. Is it true? There was one thread here that someone had claimed that it was actually much heavier.

I was planning on visiting the LHS as he has both in stock and hopefully, he may have a scale.

Also, what prop combos with these? I was planning on 14x6 for the 91 and 16x4 for the 108.

Thanks and Happy Holidays.

My UCD 60 has the Magnum .91 TWO STROKE and it's enough to 3D. Hovers around 1/2-2/3 throttle. Hobby People runs a sale a couple of times a year on the Mag .91 for $120. I paid $150 for both of mine and I'm happy with them.

I use an APC 14x4W prop. I found the 15x4 spools up too slow and doesn't pull much harder.

Great Combination.

My 46 size has a 91 fs and is really over-powered (just a little/not) This plane likes power, not for speed but pul-l-l-l. Think the bigger engine would be my choice, use the left thumb. Very fun plane.[&o]
