EMAC - Electric ONLY IMAC Events
I built a 118" Carden Extra as an electric and it worked out well and I can fly 2 Unlimited sequences with it. 4 7S 9000 mAhr Revo batteries, MGM400A ESC, Plettenberg 37 Evo motor, Mejlik 29x13.5Q prop. I took a lot of weight out of the standard kit and manages an all up weight of 37.5 lbs. It...- gregm

IMAC JTEC 2.7m Extra 300CS
The gear is centered in the slot. The two formers in the middle are just a piece of lite ply, about 3/4" wide with a notch for the longeron. The rear one replaces the center portion of the kit version that is very weak. After I sheeted the bottom, I cut out the LG slot a 1/4 inch wider than the...- gregm

IMAC JTEC 2.7m Extra 300CS
It looks good so far. I also found that some of the formers break really easy during installation, I broke my share. This photo shows the extra formers and sticks I added to the bottom, I think it makes it more like the 3.1m version. I also extended the corner 45 degree 1/4 x 1/4 longerons back...- gregm

IMAC JTEC/ Radiowave 3.1m competition series
I used only 1 Futaba BLS177SV per aileron which is about 500 in-oz. Others are using the same setup on their 40% Extras, so it is plenty for this size plane. My full setup was posted here...- gregm

IMAC JTEC/ Radiowave 3.1m competition series
I am flying the 2.7 CS with an electric setup equivalent to a 100cc motor and it is very competitive flying IMAC Advanced against larger planes. Very little mixing is required to take out any rudder coupling. I was very weight conscious when I built it because I knew I needed 8 lbs of batteries...- gregm

IMAC JTEC/ Radiowave 3.1m competition series
On my 2.7m CS Extra, I shortened the ailerons so that they stop inline with the ends of the stabs. I also reduced the elevator to about a 1/3 of the stab chord. I have a roughly scale rudder counter balance, mostly because I like how it looks. I am quite happy with the way it flies and did...- gregm

Electric Competes and Finishes 2nd in Advanced
Thanks for that, suprisingly to me and Wayne Mathews as well, that some judges chose to give me as low as a 7. Since I flew most flights and never heard my airplane at all, I am not sure why. I think noise is a serious problem facing IMAC in some regions, and unless the sound scores are...- gregm
