Pilot-rc Predator 1.8m
#26
My Feedback: (10)
Anyone able to measure their 1.8m Predator for width and length? I've tried emailing Pilot on FB and their site to see if the dimensions of my rabbit VT90 would fit and haven't got a reply (I can't make a telephone call during normal business hrs most days).
I'm really looking at the RTF version so I can get in the air quickly and get my waiver already this summer. My work schedule is destroying my build time (again).

I can't tell you for sure but the k85 fits. It is not much smaller that your engine. The pics I have seen have plenty of length room. At worst you would have to remove an 1/8" per side to get the diameter fit.
K-85
Specifications:
Diameter: 82mm ( 3.22" )
Length: 228mm ( 8.97")
Weight: 880g (1 lb 14oz)

1.8 predator
I believe im the first to have one flying here in Australia
fhe plane flys quite well for a small jet . Im using an ACE 60 TURBINE of grass seems to get airborne ok in around 100mtrs
change the servo mounts to ali and dont use the wood
ive been doing some playing around with the CG . Balancing it right way up and upside down there is a big difference in the CG .ive found it to be very nose heavy but im working to fix the issue .
all the hardware is good . Rettacts are good
although ive found i have to plug the battery in at the start of each flight
all the fuel system components are good quality too
one thing i didnt like was the big opening for the nose wheel so i made my own door . Apart from that its stock standard
Carbon door and a small flap at the front

Looks good! Anyone has any problems with the live hinges? Flaps are a bit though to move to full deflection and discovered a small broken piece of the flaps live hinges. Anyone any solution for this? I was thinking to cut the flaps off the wing and attache it back on with hinges/tape or silicone hinges.

Hi Christiaan,
didnt have any any issue with my flaps. My
build is progressing now that I’m back from my break. Have the engine in, fuel system is just about hooked up and starting to populate the equipment board.
I am changing the stock gear controller out for a Xicoy unit. The stock one works fine but I don’t like the fact you have to unplug the battery when the receiver is turned off so going with the Xicoy to fix that.

I should fly mine soon. Got some build photos and comments on my FB page on the build. Overall very straightforward. Came it at 7.9kg dry so should fly well with the M70

Hope this helps. Feel free to message if you have any questions. Once I’ve flown it I’ll post up the results. Won’t be for another couple of weeks.
Cheers

Cool. Pulled the trigger. Didn't realize they came on a slow boat, so won't see mine until late April. The SW80B from CRXturbines.com is actually rated at a little more than 80N of thrust, almost like an 85, so I should have a screamer! I build simple so I shouldn't be too heavy.

g'day gents
ive flown my 1.8 predator with the ace60 in it
after a few flights i couldnt figure out why i had so much up trim , even after moving the ECU battery as far as i could go safely it didnt change the trim and needed a fair amount of right aileron trim
so out came the incidence meter , and to my amazement everything was wrong
ive been speaking to jeremy_d about this issue and he has come up with the same problem , dont take the fuse moldings as being correct and accurate !!!! THEY ARE FAR FROM BEING CORRECT
it would pay for anyone who builds one to check it over as myself and jeremy have done
according to pilot everything is ment to be set at 0 degree's the left wing is 0 with the engine mounts BUT the right wing needed to be moved 1.5mm down on the leading edge to be at 0
both tail planes were again checked and were found to have .-5 degrees of incidence ,, left tail plane lines up with the fuse moulding (although still out of WACK ) but the right doesnt
I do like the look of the plane BUT it does need work ,, and now its getting repowered with a jets munt VT80 the 60 flies it fine but its not fast
as jeremy said the down fall is having to unplug the gear and break control unit after each flight ,, it stays on when the plane is turned of ..
so now all the incidence measurements and been checked and corrected ,,, so hopefully it flies as good as it looks

Finally got the first flights done today. Great flying jet. Needed a few clicks of up elevator trim for level flight even though my cg was spot on if not slightly reward which was corrected after the second flight. Using a Jets Munt M70 which is a great power combination. Cruises around nicely on 50% power with plenty of punch at full throttle. 7 minute flight time and only used just over a litre of fuel (tank is 2L).
It’s very stable in the air and slows down nicely for landing, looking forward to putting in more flights on it
