Hey guys,
Did you encounter any difficulties mounting the motor and or motor box?
I see no obvious way to screw in the bolts holding the motor box to the fuselage. Neither 450kv motor I have fit the motor box and either will need extensions to get the prop in the correct location.
I hope you’ve had some more good flights on your Apollos.
thanks,
Will

Hi Will.
I've had 20 flights now. Just about got the trimming and rates as I like them and, its so straight and enjoyable to fly, its just great.
Getting the motor box on is a right fiddly job.
I used a ball headed hex driver, which goes through the holes where the motor attaches, but, the hex driver is then on an angle and wants to push the bolts at an angle and cross thread them......with patience, 3 hands and a lot of cursing, they bolt home.
you can just get a small ring spanner through the side holes in the motor box to hold a nylock nut while you fasten the motor to the box from the front.
I used long fawceps to hook a washer onto the bolt on the inside of the motor box before doing the same with a nylock nut, then , once on a turn or two, I got a small ring spanner onto thr nut while I tightened the bolts from the front....phew !!!!!!
As I said....it's fiddly, to put it mildly.
I had to use stand offs for the motor, that just added to the fun while attaching the motor......an extra pair of hands is a great help to hold stuff in place.
The prop adapter lined up perfectly for the cowl.
If you have a swear box, you'll be quite well off when you've Finnished 🙈

Having used up my monthly allotment of profanity, I decided to ponder the motor box issues. 4conclusions:
1) it is easy to mount the motor to the motor box before the the motor box is attached to the airplane
2) it is almost impossible to mount the motor box to the air plane with the motor already mounted
3) it is a PITA to mount the motor box to the airplane without the motor attached
4) it is much more difficult to mount the motor to the motor box after the motor box is attached to the airplane.
So I decided to go a slightly different route. I screwed the motor box bolts through the T-nuts from the back. They now serve as alignment pins for the motor box. Mounting the motor to the motor box is now much easier as I can access the stop nuts through the hole at the back of the motor box. When I am satisfied with the motor location, I need to replace the current motor stand-offs which are too long, I will glue the motor box to the fuselage.
i also posted photos of my modification to the tail servo locations.

Hi Will.
I like what you've done there...I can see your pull pull rudder arrangement.
How have you done the elevator servo / servos and push rods please.
I'll be really interested to see how little weight....if any you need to balance her.
I might follow your route there.....looks very promising.
Well done 👍

I missed the elevator location.too busy studying the rudder servo....is it a split push rod.....one to each elevator half ?
Thanks.
Kev

Hi Kev,
Two seperate carbon fiber rods one to each elevator. Joined just before the elevator servo. They sit above the servo lead tube, but everything is black. I’ll try to get a better photo of the servo end.
The motor is an E-Flite power 60, 470kv. The Turnigy motor recommended above is currently out of stock. Hopefully minimal weight required for balance. The final test will be the performance in the air.

Thanks Will....I understand the elevator set up now.....I like it....we're all dying to see if you need any nose weight or not.......'or not' would be a great result.
Many thanks.
Kev

Well, I did a preliminary C/G check today with the wings attached, but no landing gear, T-can or canopy. The motor will also be moving rearward about 10mm. Using a 6S 5000 mah lipo I was able to achieve the proper C/G with the front of the battery about 6cm behind the fuselage former. I am pretty happy as it seems my efforts have paid off. Once I have the Apollo in RTF condition I will report back on the final C/G result and, of course, the actual flight performance.

Great result, well done 👍
