its a cmp spit, sc 108 2s up front, it" was" a really nice spit, loved flying it untill i experienced reciever failure due to interference from soddin arc welder near bye, ( 35mhs, old school!).

mk1spitfire

An arc welder...!!! ***, You fly close to industrial units?

paul cov

Right ok its arrived!, on 1st inspection everything seems to be there, and what a nice spit she is, only thing concerned about is the elevator push-rod assy, cheap and nasty, will change these, what size carbon rod did you use for yours, and did it flex much?, might use the 2 into 1 system with metal T bar thats adjustable, the only problem is making sure it does,nt flex to much,or move around while in flight.

mk1spitfire

I guess now you see why I changed the wooden dowles to carbon rod. I can not remember what size outside diameter they were but the insides took my 2mm rod that connected to the elevator servo. This was roughed up and super glue in, could use expoxy too.
Only one carbon rod had the metal 2mm rod inserted.

I think the carbon rod had about 2mm wall thickness. Both carbon rods were bound together with nylon fishing line and super glued with rocket power (cyno chyristals)

Hi Andy, the B17 is,nt mine it belongs to a club member ( Nuneaton Aeromodelling Club) his name is Byron, and he only bought it to the club field once, but she is a beauty and sounds great in the air, 12ft span, 4x52fs engines, hope this helps, will try and get contact details and put on this thread.

No...no....no, but we do fly near farm out buildings, and the farmer has a fetish for welding anything, we have tried explaining but falls on deaf ears!, will go with your idea of carbon rods me thinks on elevators, and will beef up front end, firewall ect, ailerons and flaps done already!, her indoors is pulling her hair out, (not another bloody plane.....lol).

[X(] Oh crap!, have just realized ive installed 4 servos that are Ni-cd 6v rated and im running Ni-mh power supply on 6v 2600 mah, apart from running a bit slower, should there be any other probs do you think, dont really want to change anything.

mk1spitfire

I dont understand, 6v is 6v whether from nicad or nimh, why would it run slower?

BobGeezer

As I understand it, NiCd have lower internal resistance than NiMH. 6v is 6v, but you might need a higher Ah (or mAh) pack if you choose NiMH cells owing to the lower max power rating. If continuous amp draw matches for the 4x sevos and NiMH pack, then fine... Otherwise, reinvest.

Hi,buddies,i want to show you some pics of my modified spit. bought the plane from RCtecnic,(spain),this spit(mine) is a full replica of the kyosho 90 spitfire,same weight,airfoil,size,etc.much cheaper than the kyosho spitfire.

Very nice kurrikan, and i suspect that your spanish is alot better than mine, thanks.

kurrikan

thanks paul.please could you tell me the rates of ailerons,elevators,and ruders.and the CG point??


mine has the cg point at 135mm,a little nose heavy,but i think is better.

final weight:5 KG.(10 pounds).good weight for this size

balanced without adding nose weight.

I have had this plane for a couple years now. Initially had a saito 125 in it using a 15x8. Stock gear. Plane flew great and has been mentioned, shes a real floater. I use flaps simply to slow her down as she doesnt need them for lift even in a dead calm condition.
Ive since taken the 125 out and put that in plane that needed the power(TF P-51 60 size). Now...this 90 size Spit is flying with a saito 91 and she still flies well. For its size, it weighs the same as most .60 warbirds....mine weighs 10.2 pounds last time i put it on the scale
Anyway.....ive used the stock retracts for the last 2 1/2 years, but now im putting in electrics. Both horizon(the e-flite retracts) and those from places like hobbyking would work fine and you could keep the wing in two pieces if you want without having to reconnect the fittings for a retract servo.
Myself, I have the e-flite 90-120 size in a graupner fw-190 d9 and they work great. I bought the 5mm strut size electric retracts from hobbyking and they only cost $8 (USD) per unit. You do have to get 5mm struts separately.

Hi kahlog,I visited king hobby and really have an amazing price compared to other similar products such as LADO electric retracts
hobbi king is a very good option the prices are more cheap than EEUU or europe[8D]

kahloq

If you order some....make sure to also order or have on hand some 3mm grub screws(set screws) to hold the strut wire. The retract units i got didnt have any grub screws in the package and it takes two per unit to hold a strut in place. Im sure HK also sells 5mm wire struts, i just havent looked.

thanks

Hi Everybody

I have almost completed my Kyosho spitfire. The last thing I want to do is to paint on a yellow leading edge on the wing, which I think looks really good in the air. So I have the spray paint to hand, and the masking tape ready to apply.

I then have started to worry that when I remove the masking tape it may pull off the Kyosho covering / paint, has anybody any tips or done this?
