Thread: Venturi
20/10/2019 08:53:09

Hello

woukd a 3D printed PLA or ABS venturi stand up to the temperatures around that part of the engine. Say on a 40 sized motor. This is an open venturi ( FF/CL) as opposed to an RC carb assembly.

Cheers

Thread: A sticky glassing problem!
05/10/2019 07:18:55

Quick question ... is SP113 still available? Used it in the past but ripmax don't seem to list it and coming up short on google.

dont like the EzeCote/PloyC stuff as in my experience, even if left a long time (months) to harden it goes kind of rubbery and clogs the paper when wet sanding with Wet&Dry.

Cheers

Hi Don

got the cam screw in post. PM me the cost or I can PayPal you the price of a French pint!

Thread: Hammer F3 build (another another) - glider newbie

Hi

making some headway on the CrowBraking and all that ... https://youtu.be/b5uuwhR2-5Q

Also, couple more questions.

Re Q2 earlier. I've just dismantled the connectors and inserted the pins ... pin to pin as a sliding fit. Then heatshrink. So it's a mechanical join as you would normally do with extensions I guess. Any opinions if this is a bad idea.

No experience of he kind of forces on the control surfaces for a model like this. Are regular 2mm threaded pushrods OK. Z bend one end and M2 Clecis other.

Hello

just thought I'd check out this crow braking malarkey before I start covering wings. I realise the Spektrum DX8 isn't ideal but I'm struggling to get it working.

Just thought I'd double check that the flap servos should be mounted as mirror images, as per ailerons. As in, the servo horns should be 'towards the tips' on both wings. Can get flap action right but mixing throttle as master to right flap causes left flap to move opposite way.

bit more reading I think.

Not sure why there's two identical posts ... bl@@dy iPad!

Hi

the cam screw fell out of the carb on my Irvine 36. Don't suppose anyone knows what thread it is. I've tried 3mm and 3.5mm but no go. If I can't get the spare part I'll have to use my limited skills on my ancient lathe to try and knock up a replacement.

You can see in the pic the part that's missing. I've scrounged the part from a NIB 36 but would like to replace it. Same part on Irvine 40/46.

cheers

Hi

goodluck with your build ... here's my F86 Sabre ... Free Flight Veron (Phil Smith) F86 Sabre ducted fan (TD 049).

Seriously though , where do you get your balsa from and how much control do you have over asking for specific grades etc. I'll be starting my Canberra soon but will be following you guys on the Sabre builds very closely.

Goodluck

Mike

Thanks for links Denis ... will checkout.

Had this dremmel router attachment 25yrs forgotten  about  in back of a drawer. Brilliant for routing out foam. The number of times I should have used this but gouged away at stuff in the past.

Hi

first cuts ... knocked up a little tool out of a lolly pop and a 10A blade for cutting out e inserts. Had to shave 10A a little to fit rearmost position. Using Gorilla glue.

Hello Trevor

thanks for the feedback.

Q12) I've seen on some threads where people have queried the actual position of the wing (LE as a reference point) versus incidence and effect on flight characteristics. The lower wing section and the moulded wing mount of fuse seem to match spot on with the LE of wings at lip of mount. Any feedback or experience on that score?

Cheers

Mike

Hi

Q1) I've carefully tidied up the hinge line to open it out 1/16 of an inch underside. I'm getting 70degrees of down on Flaps and Ailerons and about 15degrees up on both ... without too much force having to be applied. Is at sufficient?

Q2) I'm using KST DS 135MG slim servos for ailerons and flaps. The servo leads aren't long enough. What's the usual form in glider world ... get the solder iron out and splice extensions. The foam channel in wing isn't big enough for a regular extension leads and their sockets.

Q3) I've seen wings using Deans connectors ... anyone got any advice. Being lazy, can check that out myself.

Q4) In the picture of the servo ... is there any advantage to having the servo arm further away from the hinge line or closer. Just thinking of the mechanical movement versus the geometry of the supplied servo horn in same pic.

Q5) How do you fix in place that kind of horn ... new to me. Is it a kind of fit and melt or glue thing?

Q6) I'm using Spektrum DX8 Tx. I'm thinking it should be possible to set up V-tail and CrowBraking? Probably going to revert back to Futaba at some point next year or the year after.

Q7) I'm going through a 'let's glass everything' phase ... mainly to skill up on glass/spray paint finishes. I'll have a decent amount of Oracolor left over, from a current project, for a nice paint scheme. So was thinking of glassing wings in lightweight cloth, SP113, peel ply and 2K Oracolor. Hopefully should keep weight down by only Using Paint on tips and LE. Is this a really stupid thing to do given that I read a lot about how Hammers love ballast!

Q8) If I did loose my bottle on the glassing option ...and go with a straight varnish ... what's recommended in the U.K.

Q9) Anyone 'modded' a Hammer for aerotow and is that a stupid idea full stop

Q10) The supplied snakes look a bit awkward re termination. I'd just use a Z bend at the tail end but look a bit flimsy up front for soldering a regular 2mm threaded coupler. Any ideas?

Q11) Am I OK to ask more questions

Cheers

Mike

Hello

managed to knock off a couple of projects ... an original Obelix and a new version one.

Time to start the Hammer. What with being a slope newbie I'll have lots of stupid questions.

Having researched the available Hammer threads I've now totally confused myself.

Thread: Irvine 36 - tuned pipe
15/08/2019 14:08:57

Hi

Lol .. I guess what I'm saying is ... not really bothered per se but if anyone has an Irvine 36 pipe and manifold sitting in a parts box, in the back of a drawer under a cupboard in he shed ... and they know they aren't going to use it again ... I'll have it off them for £20.

Cheers

Mike

15/08/2019 14:03:55

Hi

understand what your saying but the Irvine 36 setup was apparently fit and forget and optimised for the Irvine 36 specifically. I guess you'd still get differences depending on fuel or prop ... but I'm guessing it's pretty close to being optimum per se ... what with being designed for that motor?

The Weston Mini pipes aren't going to be as close.

Its no big deal ... it's not like it hasn't got enough grunt ... just would prefer the Irvine specific setup because of my OCD :0

15/08/2019 11:47:39

Hello

thanks for the feedback ... it was really the Irvine tuned pipe system specifically for the Irvine 36 I was after. It's kind of fit and forget. Would have just rounded it out nicely.

How must adjustment and faffing on are the alternatives as mentioned?

Cheers

Mike

Hi

finished a very long term glassed 2K finished profile mini Loaded Dice. Flies great with an Irvine 36. Wouldn't mind sticking an Irvine 36 tuned pipe system on it. Anyone got one they are willing to sell on for a sensible price?

Cheers

Mike
