Joe, yes I routed the lines out the side to make sure I cleared the pipes.
Okay guys. I know some of you wanted to see some comparison pics with the QQ Yak. I also thre in little brother, the 88" EF Yak 54. So I got off work early, and it was so nice outside. So I shoveled some snow out of the way , and took some pics.

Okay, moving along.........
I finished up the cowl baffle and cowl mounting. The Baffle plate is a little thin for my liking. (Sorry Chris). Like the 88" Yak I reinforced the baffle with some fiberglass cloth and thinned epoxy. on my 88" Yak the plastic baffle started cracking because of the air pushing on it.
First I determined which louvers I wanted to cut-out. Then I cut a piece of FG cloth and made sure that I covered the cut-out area. Masked off and shot some 3M spray adhesive, and tacked down the cloth. Then with some 15 min epoxy, thinned a little with some rubbing alcohol, and lightly brushed it on. I would of used light-weight FG cloth, but I used what I had on hand. After the whole mess cured, I cut out the intake holes, cut-sanded-epoxied the baffle plate in the cowl. I finished off the baffle with a little black model paint. once the Baffle was set, I cut holes in the cowl for fuel dot, vent line, and access needle adjustments. I am not running a choke servo or linkage. I just have a hole on the bottom of the cowl so that I can just 'finger' the choke.

Good idea on the baffle--I will be doing that as well. Nice pics also..looks like when all 3 are lined up the gear location is about the same for all three--good for me since I gotta fit it in a 6 1/2' pickup bed!

Hey all,
Glad to see the thread has been active while I have been taking care of family Xmas stuff.
I did have time to get everything ready for CG check and engine testing, but I had a couple of set-backs.
- upon final CG check, I was way nose heavy I have to mount rx batteries at the back end of the canopy area, behind the rudder servos. Because the battery leads are only so long, and I did not want to cut and splice the batt leads, so I had to redo the radio gear lay-out and shift everything back as well. Also I have a alternate ignition battery mount area behind the wingtube just in case I have to move the ignition battery there.
- Chris Hinson sent me a 5" straight SWB rudder servo arm, and the geometry for pull-pull constrols were not correct. The rudder servo arm needed to match the rudder control horns measured at 4-3/8" w/ offset, like the 4" SWB off-set servo arm. So I modified the 4" arm I had and made carbon fiber arm extensions. Worked like a champ, and now I get nice cable tension through-out the whole rudder deflection in both directions.
- One of the used Hitec HS5955TG elevator servos must have a bad circuit board, cause it would not hold programming from the Hitec Servo Programmer, so I went ahead and replaced both elevator servos just to be safe.
Everything is ready for engine test and final check. Maiden willb ethis Friday. Will have pics and video!
