well this happend a few weeks ago but lost my nexstar due to a complete receiver battery failure had a fly away and then a nice crash no saving this one.
so the os 61 got a transplant in to my great planes cub that was maiden tonight flew nice need to get a slight issue with the ideal worked out like to run high but fly's great and sips fuel
after flying my nexStar for the past 3 years on a O.S 46 la it was final time for an upgrade in the engine department. so after finding a O.S. 61 four stroke at a swap meet i got around to putting it in no bad to do. need to take all the weight out i had on the nose might need a slight amount of tail weight now but not sure. engine ran great now time to get it in the air and see what she will do. and btw an os 46 la will pull a nexstar around the sky just need to be the right prop and it will fly not fast but not vertical. i just wanted a little more under the hood and was tired of cleaning up two stroke mess off the side when done flying
