at 150 your CG is way too far forward. Once again the gear retract forward so it needs to be balanced with the gear DOWN. I have mine at 165 right now and it still feels nose heavy sometimes. Get rid of the blanket around the pipe unless you need tail weight. Its a dual walled pipe and the outer pipe never gets much more than 100 F. Put some padding between the wing spar clamps and the tanks, the tanks are not thick to begin with and it will erode thru. I cant really tell from you shot positions but you pipe gap looks on the small side. It should be about 20-25 mm. One last thing-Move your cables on the stearing servo as far in as possible. You have then set for max throw right now. These can be squirrels on the ground and you are just going to make it worse with all that throw. Have fun. Scott
