Andrew767 Posted October 31, 2013 Share Posted October 31, 2013 Hi Sparks What diameter spinner would fit that cowl please?. Andrew Quote Link to comment Share on other sites More sharing options...
Martin U Posted October 31, 2013 Share Posted October 31, 2013 Hi Andrew Looking at mine I'd say it is 32mm. I must say that with a little heat I'm sure this could be formed from a yogurt pot.... martin Quote Link to comment Share on other sites More sharing options...
Martin U Posted October 31, 2013 Share Posted October 31, 2013 As I've already said I am adding some lite ply to the fus between F2-3. While finalising the trial fit I realised that the outside at F3 curves. With ply stuck to the balsa this will be harder. As the weak area seems to be the thin section between the wing and cockpit I shaped the ply as per the photo attached. Quote Link to comment Share on other sites More sharing options...
Andrew767 Posted October 31, 2013 Share Posted October 31, 2013 Thanks Martin Yes i'm sure you're right,i'll give that a go.....also can you tell me the measurement from the firewall to the spinner please? Andrew Quote Link to comment Share on other sites More sharing options...

Martin U Posted October 31, 2013 Share Posted October 31, 2013 Hi Andrew As you can see from Sparks photo, assuming the cowl is flush it would be 9.2 Cm You could reduce that distance by taking the cowl outside the fus. [not sure that will work as I've not got that far but it normally does] The plan shows 7.2 cm so I'd say there is 2 cm of scope to fit the motor/engine of your choice.

Sparks Posted October 31, 2013 Share Posted October 31, 2013 I agree with Martin's measurements. The cowling could be made usable with a 35mm dia motor by chopping off 15mm from the front of the cowl and gluing on a suitably shaped light ply facing. Having said that, probably just as easy to make a balsa cowling. I'll probably leave that until after some test flights to optimise the motor down/side thrusts.

Kevin Fairgrieve Posted October 31, 2013 Author Share Posted October 31, 2013 Some nice work going on here people. Any one going to do a dedicated build thread? I will be once I have something positive to show. (Should be after the weekend.) Kev Quote Link to comment Share on other sites More sharing options...
Andrew767 Posted October 31, 2013 Share Posted October 31, 2013 Thanks to both Martin and Sparks....I'm going to build from the original mag plan which shows neither the canopy or the cowl outline so those measurements are very helpful. Moulding the cowl myself also means it can be made to fit the motor i'm going to use (ex foam-e Acro Wot). Also i think i have an ali u/c that will do. Kev....I might do a build thread but i will have to play in the sandbox first to learn how to add photos and it may well be the new year before i start......after you mate!!

John Roberts 9 Posted October 31, 2013 Share Posted October 31, 2013 Just a couple of shots showing the contents of the HMS CNC Wood Pack and the Additional Wood Pack. The extra wood pack is a bit skimpy on contents but, in fairness, the overall contents are comprehensive and the wood grades seem to have been quite carefully chosen for their various applications. So, despite being a bit on the pricey side, I think it represents a good choice for first time builders or lazy folks like me who are too idle to cut the bits. For anyone without an existing stock of balsa it would be easy to spend almost as much buying in enough balsa much of which might eventually go to waste if they didn't go on to build something else using the surplus left over from the Mini Jazz build. I hope to start a proper build blog shortly (resisting temptation for a few days because we might have sold our house and I don't want to have to transport a partly constructed plane!).

Ian Southerton 1 Posted October 31, 2013 Share Posted October 31, 2013 Threw me for a while, fuselage sides are in 2 pieces! A lot less hassle than cutting all the ribs out-i made an ally rib and cut round them. Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted October 31, 2013 Author Share Posted October 31, 2013 Thank you Mr HobbyKing, my setup arrived today. RX bound first time no problems (no range test done yet). The LiFe showed 6.4 volts after a balance charge, so not sure about that yet. In fact I am not convinced it is going to fit in the space. Servo`s seem happy enough on that voltage as they are only rated to 6 volts. The switch is an unknown, both in size and suitability. It is quite large and has a charge port. I am thinking that the LiFE will need to be removed for charging/balancing so am doubting is use in this model. Kev Quote Link to comment Share on other sites More sharing options...

Martin U Posted November 3, 2013 Share Posted November 3, 2013 We had a maintenance session at our club field, so I've been fixing the electric fence [used to keep sheep out!] Meantime I'm hoping to get the engine mount in the post tomorrow so my Mini Jazz, which looks great naked, can continue to covering.. I must have sanded half a tree off the fus to get a nice sleek shape and keep some weight off. Care warning -- I cut the cockpit cover to the guide and it is a bit small - doh. So I have a plan to fit a little balls edge that the cover can fix to. Note to self - don't trust anyone, check it yourself, and twice before you cut!!

Kevin Fairgrieve Posted November 3, 2013 Author Share Posted November 3, 2013 Well I have been busy today. Wing almost complete. Underneath that pile of magazines is the wing leading edge skin glued and drying. See.. I will do a proper build blog in good time. I am taking lots of pictures as I go along.

Sparks Posted November 4, 2013 Share Posted November 4, 2013 I have been checking the various parts from the laser cut kit and found this: As you can see, the tailpane inner 'rib' is too short, so will have to be repaced. Laser cutter please note! Edited By Sparks on 04/11/2013 15:03:30 Edited By Sparks on 04/11/2013 15:03:58 Quote Link to comment Share on other sites More sharing options...
Martin U Posted November 4, 2013 Share Posted November 4, 2013 Hi Sparks I thought I'd lost the right part and re-cut as there is plenty of spare wood! Also why did they not provide D1&2 in the pack? I made up from the surplus wood but at the price I feel they should be included. Only a little niggle in an otherwise good set of cut parts.

Kevin Fairgrieve Posted November 4, 2013 Author Share Posted November 4, 2013 Sparks. Can you photograph the plan for me, where the tail end is. Would like to see the thrust line of the tail. Thanks in advance. Kev Quote Link to comment Share on other sites More sharing options...

Kevin Fairgrieve Posted November 4, 2013 Author Share Posted November 4, 2013 Thanks. Looks completly different to the magazine plan. I am of course referring to the incidence and not the plan.. Quote Link to comment Share on other sites More sharing options...
Sparks Posted November 4, 2013 Share Posted November 4, 2013 As I have mentioned before, I am uncomfortable with the new +3deg tailplane incidence angle. I shall revert to 0 deg incidence and reduce the main wing incidence angle from +3deg to +0.5deg to compensate.. Have a look at Bango's excellent video (HERE) about incident angles and draw your own conclusions. Sparks Quote Link to comment Share on other sites More sharing options...
Ian Southerton 1 Posted November 4, 2013 Share Posted November 4, 2013 Malcom Corbin is on here occasionally, it'd be interesting to ask him why there are differences, which is best and why.

Martin U Posted November 4, 2013 Share Posted November 4, 2013 Taking shape... 1st trial fit of the main components.. Starting to look nice.. Just got the motor mount so I can fix that, then sanding and covering Quote Link to comment Share on other sites More sharing options...
