wow looks like very little damage considering how hard it went in. nice bit of flying before the crash.
700 Building the Agile 7.2

Yeah, that is a lot of space for the servos. Can you make up any shims to place between the bottom of them and the bottom plate, maybe out of wood? Also, did the posts recess properly into the plates? I always find that a problem on the goblin builds (or rebuild as the case is currently).

Thanks, Matthias. The packs will stick out from the frame somewhat, but they will be secured by both velcro and straps. As I said before, I do not think it's going to be a problem
That looked like a grenade went off in the field
Nice flying
He is a very talented pilot, probably in the top 10 in Norway.
I will try to find some spacers for the mounting holes on the servos, that should secure them into place a little better. Might do the same for the elevator servo - I'll have to take some measurements later on. There were no issues with the plates.
Thanks, Paul

Main gear assembly.
Done.
I believe this will hold the front end of the torque tube.
Installing main shaft and main gear assembly into frame.
You should be able to insert the shaft through all three bearings effortlessly - mine had to be shoved down into place, which meant the bearing did not line up properly.
Had to loosen all the bolts that hold the drivetrain together - including loosening servos.
I was not able to achieve smooth installment of the shaft just by loosening the bolts and wiggling the drivetrain. I then started looking for other culprits.
After playing around with the three "pillars" which hold the two top parts of the drivetrain together, I was able to get it right. Main shaft fell right through the bearings with no force applied.
Main shaft installed.
A package came! Wohhoo
As I mentioned earlier I wasn't quite pleased with the two front servo mountings. So I ordered some washers and servo plates - got out all the servo stuff I had lying around and set to work.
As you can see, the bolts do not fill the servo mounting holes - my concern is that the servos might move during hard load.
Finding the best washers. Black ones fit the best.
Servo stuff I had in my spare parts box.
I had three types of bushings available.
Black ones didn't fit my servo plates.
Gold ones were too long.
Silver ones, perfect length!
Ready to assemble.
There! This took out most of the slop and I now feel comfortable with the mounting of these.
Skids.
Telemetry arrived in the mail!
Rods.
Swash.
Temporary hook up LOL
Leveling swash.
Had to deviate some from the manual. Shortened the elevator link by two turns.
Tail assembly. Front gear.
Rear gear box.
Super late. Gotta go to bed. Zzzzzzzzzzzzzzz

Bought a bunch of 5000mah's from HK. One of the packs had a bad cell and an RMA request is now pending.
Preparing two packs for the maiden. I will use EC5 plugs (as I always have done on my larger helis).
Rear tail box.
Ready to assemble the tail.
When fiddling with the tail pitch slider one of the E-clips popped off?!?
Upon further inspection I could see the clips were rusted!!
TT assembly.
I removed all of the KDS clips and replaced them with stainless steel ones which I ripped off of the old JR E8.
Rusty KDS clip to the left, stainless steel JR clip to the right.
There, good as gold.
The links for the tail grips were super tight! I didn't have a reamer, so I used a trick I learnt from a guy in our local club; pop the link on the ball, then hold and squeeze the link with a pair of pliers while rotating the ball inside the link - worked like a charm
Tail rotor assembly finished.
¨
Setting the bearings in place on the TT.
The manual says there is no need to glue the bearings on the TT - well, that's a load of bull. What they really mean is, standard CA glue will not do the job - the bearings need to be epoxied into place.
Sanded the spots where the bearings are to be epoxied.
Tail supports and tail pitch rod assembled with epoxy.
This is one beefy boom! I like it
Preparing to insert the TT into the boom.
At first attempt I used oil to insert the TT, as this is a super tight fit and the bearings "rubber seats" barely fit inside the boom - I should have used silicone grease instead, and lots of it!
Should have used this (made things much easier the second time I installed the TT (yeah, I had to take it out again LOL)).
Front end.
Nearly ready!
I used my Dremel to cut some groves in the plastic of the ESC case - this to fit my temp wire underneath.
Double sided tape.
Soldering.
Soldered in wires for voltage monitoring on the battery leads.
Soldered in wires for RPM monitoring and governor on the motor leads.
Had to join two Spektrum plugs on the RPM leads. One for the ikon governor port, and one for the TM1100 telemetry.
Wiring.
After three knights of fiddling with the RPM sensor and NOT getting it to work (showed random readings on both the telemetry and ikon gov), I swapped out the Spektrum RPM sensor for a Hobbywing sensor - and that did the trick Turns out there is a compatibility issue with the Spektrum sensor and the Castle HV ESC's.
Gaui strap on the KDS LOL
Not much left.
These long bolts go through the rear of the frame, tightening the boom into place. I over torqued the nuts twice, ripping out the locking stuff inside the lock nut - luckily there was supplied a ton of extra nuts with the kit
Setting her up for flight!
FINISHED!
Not my best wiring job, but the Agile wasn't the easiest model to wire...
Ready for maiden
Maiden day.
Watch the maiden on my video thread, here.

Thanks Paul. I haven't had any issues with the 500's battery packs (also HK), so I'm hoping the same applies on these - but, it is Hobby King, so you never know LOL. You just can't beat the price on the HK packs
They got some flights on them now (even the one with the bad cell), and they're working fine for now at least

I am super happy with the Revolectrix batteries
Cheaper than the Nanotechs, and much better quality.
The IR on my packs is 0.9 ohms
They have a temperature gauge on them.
A cycle count marker
And they come personalised with your name on them.
Built on the day they are shipped.

Because it is shipped by FEDEX it does get caught by customs.
But when my friend ordered 6 batteries, he emailed them, and they reduced the customs declaration to say the price of two.
