Berk. Yep seen the error

Mine has Lite ply U\C plates and they are 3mm laminate. The kit has been changed and has Marine ply plates and thats 3.2mm. Forgot to alter cnc parts to match change of material so slot is .4mm to shallow [X(] oopps. I have altered cnc to be correct for next batch

Luke I use a 17 x8 apc and I love it. But then I cant fly like the boy

I get approx 9,100rpm on the 17 x 8 with the 140L on 20\20 my 140 fz the original version was down about 400 rpm on the L

I used to get 8,300 on the 120 fz from the original first prototype with the same prop. I am now on 30% nitro so maybe we can tacho it at the freestyle this weekend.

Luke have you let Billy Bunter have a go with your 140 yet?
