RE: Balsa USA enforcer
to set the thrusrt angle on the fan pod i gave it about 3 degrees up thrust just as I would do on an pusher it seemed to work well botht he enforcers are electric now i make and sell the pods to fit a 5 " dynamax of ramtec fan units ther are fiberglass with wood inner frame

you could put shims uner the front or rear, however i have put alot of time into these pods the original pod was made from jet joe and the plans are in rc modeler magizine for the 6" byron fan you have to build that one from srcatch, I re engeerned the unit for 5 ' fans the angel I have put in to the are perfect I made a fiberglass mould and have the inetior wood parts lazer cut

There is a guy in the 1/2A forum who is piecing together a little fan unit for a .09 engine. He's doing a great job, but it looks more challenging and exacting than building a "ship in a bottle".
My guess is that you need to find the thrust angle that agrees with the planes' natural glide trim with no power.

the pods i use with the 5" fans are perfect no need to mess with the angle, i have spent countless hrs getting it right, many people who try to do build thing with no idea what there doing useally ends up in a crashed airplane
and also balancing the plane correct makes a a big difference its always better to be nose heavy than tail heavy

Well in my experience, Too Nose Heavy flies poorly.... Too Tail Heavy Flies Once... So I can only agree that the CG is a very critical measurement.

Do you have pictures of your setup and could you give a brief rundown of the reasons that you chose what you did? Please include batterys, ESC, ...

i Use 4035-640 high output outrunners for motors, castle 100 hv esc in 10 cells of lypo on one of the planes. the other has fly, fly 110 hv esc, hyperion 4035-64 motor on 10 cells of lypo ill take some photos this wekend sometime and attach as far as cg settings you arte correct most cg settings go from 20 to 30 plus % when i build anything new i start where the kit says to balance if is scratch or a modified kit ill strt at 25 % when i fly it ill get it up and flying trim it out and see from there, a dive test tell what you really need to know, now days with the internet there are so many CG caculator programs out thet that work spot on nothing like the old, (35 years ago we really need to know out stuff. I guess after 30 years in the Air Force I picked up a few pointers about aero dynamics

I have done many prop static tests on many different motors, i use only apc 11x7 onn .60/.61 engine, getting about 8 lbs of static thrust the average encorcer will be 8 to 10 lbs depending whrt you do to it even if you had a 12 lb plane 8 lbs of thrust will still make a fast plane

RE: Balsa USA enforcer
Wow, nice work! Not much left of the original Enforcer [8D] Do those engines have crankcases that can rotate? Can't figure out how you got the mufflers to both face the inside...

the motor's are the old style of magnums, where thr both the front and rear hubs come off, on the right motor I switched the front and rear to get the exhaust on the left I also took the carb apart, and flipped it so the bottom is on the top, I did this so the throttle rod to the servo is on the opposite of exhaust total weight dry is 13.0 lbs i am getting 14.8 lbs of ststic thrust, should fly very well and fast

flys great stands on its tail real well flys well over 125 mph has 15.5 lbs of static thrust and its weitgt is 12.4 lbs
stay tuned for another build it will be 30% larger nose and tail area larger , with twin .75 pushers set up just like the stock enforcer morter set up but totally altered wing and cockpit with retracts

Another Enforcer build it, as you can see its highly modified, the wig area is wider and longer and the fuselage is totally changed and longer, it will have a EDF with a 5" dynamax fan running on 12 lipo cells the lower front photo shows something new am trying a intake scoop to get more air in to cool the battries it will come out the rear of the fuse , he grey part in the canopy area is a mold I made, to vacume form my own canopy part, it will have electric retracts and doors, next step is to cover it with 1/2 oz fiberglass cloth and I will use epoxy, not fiberglass resin, a little more expensive but no stinking up the house and no itching after sanding it once that is done Ill use epoxy primer thinking of using the aluminum tape to do a all natural look.
