I screwed about 35 gram to the underside of each engine mount using longed mount screws and a extra nut to hold the on. I also screwed 80 to the firewall under the engine mount and about 250+ grams of lead sheeting to the fire wall between the 2 engine mount arms.

I guess I have 400 + grams screwed to the front of the plane

The plane is very disapointing with the 90 2 stroke on it. I'm going to change to a better brand prop. It doesn't seem to have enough speed.

Landing is a hand full, I'm going to move the landing gear as far forward as I can, tips over a bit to easy.

I guess my CG is at about 135. A nice heavy 140 4 stoke would be the go in the plane or Zenoh 23 or 26
