i had 5 flights on mine prior to 2009 when i switched to electric. ic power is os 1.2 4s, one day i will upgrade it to electric. do you think 2 4s5k batts will fit in the cowl w the motor and esc?

the fiberglass is the blown in kind so it would crack and break off where the longerons are on the back of the fuse because the thickness of the fiberglass varied so much back there. most of my cracks are on the square corners at the bottom of the fuse.

Yes those batteries will fit, I use them in my other 120-140 size war birds
There's a little bit more room in the Hurricane cowl than the CMP Spitfire cowl so I will do the same layout
No cracks in the fus at present but I guess that can change

Got the motor battery and ESC install done--- ended up being a shoe horn fit but it's all in and working, also put in a new radio tray and moved the servo's forward and now have all the surfaces working, I replace the single servo for the elevator with two servo's and the rudder servo now works with pull-pull wire, retracts are in and working, also made up a sunken cockpit, I will give it detail later

Done a wt test for the 380 KV motor and 16 x 8 3 blade prop, with an 8s 5000 battery - 73 amp @ 2200 wt
AUW with batteries just over 14 lb, C of G about 105mm 107mm with a little nose down, did not have to add any weight to achieve this
a couple of small jobs to do and it's ready for a maiden

looks good!

how will you hold the battery hatch down?

i have lots of those ntm5060-380 on 8s 5amps, 15x8x2 will draw ~46amps (8 min flite+), a 15x10x2 draws ~60amps (7 min flite), both have an extra min built in for a go round.

Its held in position with some teeth at the front and a couple of L shape nylon turn buckles at the back made from bolts that have a tab on top, I put a piece of 6mm ply behind the fg and then put star nuts in them to take the bolt, last job I managed to get the the on off switch for the flight pack in there---a tight fit
I have had good service from those motors that's what I use in this size plane

Got to the strip and taxi tested the Hurricane, after 3-4 runs up and down the strip the tail wheel gave way, turns out the ply wood block in the fus broke away, its all fixed now, I glued it back then added a 1/8'' ply plate on the out side and glued and screwed it to the inside ply block.
It taxi'ed well nice and straight, I let go of the elevator a few times and the tail came up, did not look like nosing over, I added some 1/8 ply at the back of the retracts when I fitted them to give the struts more forward rake for our grass strip, next time we have good weather I will maiden it

Had a successful maiden and second flight only a couple of clicks in the elevator and ailerons and I could fly it hand off, inverted it and only a small push on the elevator to keep it flying level, it flew very well, the C of G 106-108mm by my fingers is good, landed no bounce or nose over, I will get a couple of more flight days in and then give it some paint and detail to finish off
