RE: CA model Extra 27%?
The 27% CA kit sells for $299. It is an easy kit to build, and it builds very light. Mine was 14 1/2 lbs with a BME 50. It flys very nice and will 3d well. If you don't mind an easy build it is a good plane to have. They were hard to get because they were in high demand. Not sure if that is the case any more or not. I bought my kit last fall. If you RCU, there was a huge thread on this plane. Back when it was introduced it was only $199 and quite a few people bought one. That thread helped me a lot when I built mine. The worst thing is the instructions... they are terrible.

RE: CA model Extra 27%?
i'm going to get this plane... but.. would a zenoah G45 or G62 works? too heavy ( they are way heavier than DA engine ) how about fuji engines? is there any other reliable gas engine i can use for this plane? i'm planning to use only around $400 to buy the engine and this is going to be my first gas.. so i want a new engine not a used just in case if anything goes wrong i can send it in to fix.

RE: CA model Extra 27%?
I would not put a zenoah on this plane. My BME 50 was considerably lighter than a G45 and it was still fairly nose heavy. I don't think it would fly like you want it to with a zenoah or fugi. I always buy used engines, maybe I have been lucky but I don't think I have ever bought a lemon. I think you could get a ZDZ 40B for less than $400 and it would be much better suited for this airframe. The biggest thing with buying a used engine is watching who you buy from. There are a lot of sellers on here with great feedback, and you can buy from them with confidence. Good luck.

Try a brison 3.2 you might be able to get it at under 400.00. A zdz40 will do IMAC and some 3-D but I can't remember hearing anything on this engine plane combo. I have one ready to go with a old Q-52xl unsure if it will hover it but it should fly nice. Hope to get it in the air tomorrow or late next week..
Check out the Brison 3.2 before the zdz it will be a better match..
Just checked 499.99 for the brison. It is a good engine for the price though.. I would call sometimes they have better prices advertised.
I am just at the balance point with the Quadra, so I don't think the engine will shift things to much..Quadras ain't light but this one does have electronic ignition and a lightend head.

RE: CA model Extra 27%?
I am not sure on the 40B engine, but I know that a normal zdz 40RV would hover the plane easily if it came out as light as mine. I have had a couple of the 40RVs and they have very good power for a 40cc engine. The 40B is a little less powerful, but I am not sure how much. My plane must be very different than Vsnap's since mine was nose heavy with the BME and his balances good with a Quadra. There is a big weight difference between those 2 engines. No telling, everyone builds differently, and things don't always turn out the same. I agree that a Brison 3.2 is a very good engine. I have one of those in my BME Edge and it runs great.

RE: CA model Extra 27%?
I think the 2.4 would be a good engine if you don't require a "blast" out of a hover. I think it would have some pull out and I know that is a real light engine. If you want total unrestricted power I think that Steve is right that one of the light 50cc would be your best bet. Your other option would be a Moki 2.1 as it is light and powerful, but most people (myself included) have no desire for buying gallons of glow fuel.

RE: CA model Extra 27%?
The little metal rods are Central Hobbies push rod ends. They are designed to be JB welded inside of a carbon fiber rod. They make light and tough control rods.
The canopy is in the right spot, but it looks like it needs to be trimmed a bunch.
There are 2 ways you can hold on your wing. The easiest is to put a hard point in the wing over the wing tube and drill through it and the tube and insert 4-40 bolts to hold it to the tube. The other way is to put blind nuts in the root rib and run small bolts from the inside of the fuse into the wing root ribs. Both ways work fine.

RE: CA model Extra 27%?
measure the distance needed to set it up and shorten the motor box that amount.if you take the same amount off all four sides the incidences will stay the same as stock.epoxy it all back in and add triangle stock and mabye some light cloth and you are all set.sounds like you need to take about 1 3/8 inch off or there abouts

RE: CA model Extra 27%?
Slow up a little,,,
First: I saw a Brison 3.2 advertised in the magazine last night for 449.00 so call them...
Second: I build very light as advertised...no balance problems just plan as you build and place equipment.
Third when shortening the motor box mark the thrust lines on the sides of the box. Then cut back the desired amount glue and secure the fire wall. Now mark the thrust line on the firewall...The motor box has a downward angle as it flows back, so the engine will sit higher on the firewall for the correct thrust line.
Fourth: gone for the week so I will post pics on the wings later this week. By the looks of the build this should be set up all ready, check the wings for small holes along the wing tube on the bottom. If done internally you should see a blind nut in the wing root.
Finally: Got two flights on it Sunday, really blessed with hot weather.. Excellent airplane with the 52. Hover at 1/3 throttle, not a rocket but would climb. Easy waterfall, flat spin, knife edge spin. Locks itself into a high alpha angle just wouldn't drop a wing when I went to enter a spin without help.
The best bang for the buck I have ever had. Good Imac platform really crisp in lines just needs slight elevator in knife edge.
Lost hatch on second flight, make sure the tabs are in good. Will be ready to with a couple hours work. Nothing else broke except cockpit floor.
Have fun with it...

RE: CA model Extra 27%?
thanks for responding....
how do i find the thrust line? i don't see a blind nut anywhere on the wing... here are some pictures, someone might be able to figure how this wing will be mounted

RE: CA model Extra 27%?
Is that small hole by the wing tube threaded? Is it a hard block? If it is it is probably ment to be threaded so a 1/4x20 bolt will lock it to the side of the fuse from the inside. Another method used as per plans is a small bolt through the bottom of the wing into the wing tube so check the tube and wing for a corresponding hole.
For a secondary back up drill the rear dowel pin for a c-pin incase the wing bolt backs out or pops the head off (nylon bolts can do this).
