Hay Hemi,
I agree with Bo 100% and I would add one more twin tainer Bo didn't talk about...and that is the .25/.40 Twin Star that Tower sells. I've two of them...one with a four engine mod...and this flys very nice too. I agree that the Cedar Hobbies Twin Stick is a nice flying model...and mine was well built. I do not have any hands on experience with the Dual Ace...but all the reports I've read on the airframe here at R/C Universe, give the model a good thumbs up. The Dual Ace is the most expensive of the twin trainers.

There is also write ups about the KMP P-38 by Twinman. He knows twins and I would suggest you read anything he has written on the subject of any twin. Just good information anyway you look at it.

Cedar Hobbies Twin stick is the best bang for the buck...at under $120.00 a good deal...and an excellent flyer...it does look ugly as sin...but it is in the ugly stick family. My ugly stick uses two K&B .40's. You can use any .40/.46 size engine you want on the model...and it will fly well.

The Twin Star can be had for about $109.00 & with Towers special offers, less...and a great flyer too...and an OS .25 will fly it with authority. I used two .32 on mine...the only issue I had with the Twin Star was the small 4 oz. fuel tanks. So I would suggest using a .25 on this airframe...you will not be disappointed. The second edition made some nice upgrades to the kit, and now uses a good heat shrink covering. My four engine Twin Star uses four .15's.

Soft Landings always,
Bobby of Maui
