The plane will almost certainly come out tail heavy. So a light weight engine is not needed or desirable. A heavier engine will not hurt. Also in your build keep all weight as far forward as possible including building mounts for you batteries and ignition module in the cowl as far forward as possible and keep everything in the tail as light as possible. You will probably still need to add nose weight but maybe not too much. Thats how it was on my 72" wingspan CMP Zero. However, it should be a great flying airplane.

Hs645mg are more the enough for this size plane at half the price of those futabas. You also don't need a $650+ motor like the da50. Being a round cowl...you could fit in an eme60 easily and could also equip it with an electric starter unit. That would be usable nose weight.

Wow! Lots of good tips gents. Thanks! Those are all new to me.

Flying weight would be around 18~20lbs, what minimum torque of the servos should I get?

These make great flap servos.

75 inch-ounces. Dan.

Your zero is more then likely going to be closer to 22 pounds. ESMs listed flying weights don't include retracts. Also....troybuiltkodels has PowerHD metal gear servos with 270oz of torque for $14. I have a bunch of them in my 89" spitfire and they work great.

Tonight I was able to fuel proof the firewall and front formers with 20min epoxy.

Nice! Another one I hafta get! So the wingspan is definitely 88"? Some websites are still listing it at 80".

carrera mike

TGIF! Able to work on the wings and installed the aileron and flaps, plus getting them set up for the servo and horn.

Found a test pilot too whos brave enough to do the functional flights in few weeks..

i couldnt agree more than that! i also have cmpro zero 72¨ and its one of my best planes! its about 9,5 kgr!! now after some repairing , i have dle 30cc and it flies like on rails, i had to make a pair of split flaps though for slow landing approach. i had to put over 1 kgr of dead weight in front for balancing at about 1/4 of the wing root. my estimation about esm zero is that if you would like to balance it at the same point (1/4 of wing root chord at the point where wing meets fuselage) you will probably need over 2 kgr of dead weight in front with a 50-55-60cc gas engine(except zenoah), but i am really sure that plane will fly lovely. .....why not a ......dle 80cc for a more scale like prop;

That is my #1 worry.... how much weight I will need up front to balance. Great advice in picking the heavy parts for the front (i.e. servos, batts, engine)
Gettign the DA-50 and pitts by the way. Though Im curious about the 80 cc. I do want to stick with scale flight characteristics.

Here some pix from last nights work on flaps.

Mike,

I am looking to purchase one of these.

Any pictures of the interior(Servo trays and/or formers). I am wondering if there is enough room for a smoke pump and tank.

I am preferring one servo for the flaps with bellcranks.

here you go. I could take more if you want..

Flyin Hwn

Thanks Mike,

Is that all the formers? Pre-glued?

Are the wings glassed or covered? I like to do panel lines and weather

Cowl diameter? I have a G-62 looking for a home

How about a picture of the wheel wells

Sorry for all the questions but TBM site lacks necessary info

Mike,
looking closer at your pic of the wing servo bay, I see that the wing is covered.


Thanks

You should glue your servo blocks grain wise perpendicular to the hatch plates and not parallel to prevent them from splitting from the plates.

dgiatr

is the wing ONE piece or two;is it 88 inches span or 80 inches;
thanks

carrera mike

carrera mike

thanks for the tip! I did realize that after I dry fit the servos.. I repositioned all the blocks now..
also thinking of screwing and strip of popsicle stick on the backside to tie both of those blocks over the servo.

carrera mike

wings ships in two pieces but gets glued together as one..
