Hi all.
I've bought an almost finished Trainer 65. Graupner suggest using an OS MAX 61 FX or an OS MAX 65 LA. In the plane there is a Laser 100 engine. The Laser is supposed to run with a 15x8 propeller but this leaves only about ½ inch between the tip and the ground... I am going to use som slightly larger wheels, which will give me another ½ inch.
What propeller sizes would you suggest i try? Is the Laser to heavy for this plane? Ideas for improvements on the Trainer 65 would be much appreciated too.
Here are some data: OS MAX 61 FX weigh 550g, propeller 12x7 Laser 100 weigh 770g, propeller 15x8
Happy landings Henrik
