|Thread: Oleo pin adaptor|
ok thanks Denis, unfortunately my workshop is a little light on the tooling front. HK do provide an Oleo with 6mm pin which is again out of stock, maybe I wait for that one.
So do the HK ones have a solid 11mm plug rather than tube out to accept a 11mm pin? The HK pictures don't show either way. I assumed these where like the robart's which have a shaft in which the pin locates.
Thanks Dennis, did you epoxy the spacer to the pin?
These are the oleo type I would prefer, **LINK** however they have 11mm pin
I'm going to be cutting down a pair of 6mm dia piano wire torsion landing gear to attach oleos to absorb some of landing bounce. Ideally I would go for the trailing link type to give a more scale appearance.
HK have a number of oleos at a reasonable price, however most seem out of stock at the moment. Most accept a 11mm or a 12mm pin and don't appear to be supplied with bushing / adaptor to fit a smaller pin.
I've got a pair of Robart 650s for another project and they include the bushing for different dia pins, it's a shame HD don't.
Is there a standard / best practice to overcome attaching 6mm pin to 11/12mm oleo? I've had a seach for collets, bushes, collars etc, but nothing is jumping out. I don't have access to a lathe to make my own.

Looks great Tim, well done. Maiden this week??
Hi Jon and Tim,
so my tanks is 55mm tall and the centre of the carb is 18mm from the bottom of the tank. This makes the centre of the tank 10mm higher than the centre of the carb. Would you recommend getting the tank lower??
Thanks Tim, you build is coming on really well. Are you going for twin flap servos or single?
I’ve measured my setup, the carb centre line tank is 18mm above the bottom of the tank. It’s also a 16oz Sullivan tank. Is the siphoning issue only a problem when static, or in flight too. Do you think the tank is low enough?
Hi Tim, I'm enjoying your build, great work.
I'm in the latter stages of the RAF trainer version, 2 piece wing (maybe 1 - jury's still out), & laser 150.
Are you levelling the centre line of the carb with the centre or bottom of the tank? Just trying to make sure I've got the right level tank.
|Thread: Slec/Apache Chipmunk kit advice.|
Hi David, I’ve read this in a couple of places about trouble getting the fuel tank height right for the laser 150 when inverted. Do you have any lessons you could pass on please? Mine is the raf trainer version, split wing, with laser 150 inverted. Just in the final stages before covering.
Also general question , does the 6mm landing gear wire hold up, or would it benefit from sprung oleos .
|Thread: Slec apache super chipmunk|
|If anyone could take a picture of that area of the plans, it would be really appreciated. Thanks|
Ok great, I’ve sent you an email. Thanks
Hi, hoping someone can help. Does anyone have a photo of the single servo flap setup with torque rods. My plans have the flap servo in the wing, so I’m struggling to work it out. If someone could post Either picture of the wing made up or pic of the pans please. Your help would be appreciated.
|Thread: Spit 72" aileron servos|
Ok cheers guys, thanks for your help.
|Thanks all, Which 26 gram servo would you recommend? I've also been looking at the slim fit servos, used in gliders. Cheers|
I've acquired a tony nijhuis spit 72 electric. Lovely model however I'm unconcerned that the New Power XL-17hmb Servos in the ailerons look a bit on the light side. They are 3.5kg torque mini size. Would appreciate any advice on if they are up to the job before I take it up. I know some of the glider guys have to go down the slim fit servos route because of the wing build dimensions. But this spit is quite heavy and plenty of room. It's a shame to go to standard size servos because I'll have to cut a larger servo hole and build and paint a new servos cover to match. Let me know if you have any advice, my gut feeling is to bite the bullet and go bigger.
|Thread: 72” Mk5 Supermarine Spitfire COG|
Hi hopefully a quick question to someone with the original plans. If you have them to hand, could you let me know the cog, measured from the wing root please. Also any details on suggested control surface movement if they are provided. Thanks in advance.

|Thread: Matching ESC to motor & prop|
Thanks Dick, Its a Tony Nijhuis 72inch mk5 Spit. weighing in at 4760g. Appreciate your advice.
I've acquired a model and hoping to build 8S setup. Its got an AXI 5330/18 motor, and I've selected via ecalc the 18/10 prop. giving 12.5C, 8.1min flight, 1578W, 70DEG, 1.4:1 RATIO, 110 km/h. Looking at the motor results its says current 43.9A optimum and motor @ maximum 56A.
If I allow 20% headroom 1.2x56 = 67. So would a minimum 70a ESC be ok?
I'm looking at 8S HV ESC and they are very expensive in comparison to no HV. Looking to do this on budget.
Also if the battery load is only 12.5C , will that mean I don't need a really high C lipo??
Any advice would be appreciated. Thanks.
|Thread: External fixing of exhaust canister|
Ok thanks guys. 50mm p clip and m4 mail - mail rubber bobbin ordered.
Hi Denis, it's a 50mm dia canister. Would you screw the P clip retainer direct into the fuse or with cushioning too?
