Thanks R.J but I have sourced them from Bellblokes suggestion , got them this morning machined and fitted them tonight . I plan to give the turbine a run up to idle or just past and let every thing whirl round for a while then I dont know whether to fit the mechanics to the Allouete or build it up as a pod and boom first and do some flight tests . might have to beef up the turbine mounts tho which ever way I go I`ll keeps yees posted .

Looking great JCT, looking great.

Don't want to state the obvious since who clearly have it all well in hand but I trust you will be using some more engine support, I know this is work in progress so feel a bit silly for asking.

That's looking pretty cool JCT. No turning back now, looking forward to seeing a turbine Alouette here soon.

First run every thing is ok decided to go for gold and stick the mechs in the Allouete should have the brackets made and braized in by Sunday . I`ve got a set of 90 size head loaders so I`ll run the turbine up to a decent head speed with these fitted . Heres the vid

Full marks for ingenuity. I bet if you tried you could lose the fuel tank inside the covers by using several smaller tanks.

Nice job, good luck with the test flight

HI JCT

that sure is looking good, you have done a nice job of it,

you must be well pleased with what you done, top marks for that,

i see you used the glo engine case to keep the clutch to run true

did you make a new shaft for it or is the crank shaft still in it,

if the crank shaft is still in it i think it will cause a lot of

vibration,

cheers kim

Fantastic!!!!

Just a little note, you will melt the caopy from there, but your one step ahead on that I'm sure, just thought I'd bring it up.

Great Work

you will probably get away with the canopy being there as on my turbine my fuel tanks are in the same proximity if not closer.
but still looking very good

Pissing rain here so doubt if it will be flying today , -- Kim I machined the crank down and removed the big end pin so no vibes there , Bellbloke I did think I would get away with the canopy but you might be right , it would be a shame to melt it so in the mean time I`ll put in a couple of plates to deflect the heat away . Peter yes I hope to get the tank/ s hidden but it will do there till I get some thing sorted out thanks for all your support and help it`s well appreciated

Cheers Colin

Sorry, but it probably will melt. I started my Wren Predator up next to my Lama at a show and melted the plastic/glass.

Managed a run in the garden with headloaders (90 sized)1350 head speed at 109000 every thing seems fine , run for 15 mins at 110000 with no probs . Flight test next . I chopped the exhausts so the hot air comes straight out and away from the cockpit I will fit dummy intakes at some point . heres the vid sorry aboot the poor quality ( it gets dark up here quick

HI JCT

i was thinking of your exhaust looking forward,

why not give wren a ring, they do a exhaust for there turbo prop

mw54 turbine, i have seen it on the raven and it looks backwards

its round each side and looks nice, it would look cool on your heli

plus you would not have to worry about the heat from the exhaust,

i know the predator exhaust is £120 i would think the raven exhaust

would be about the same,

cheers kim

If you purchase an exhaust kit from Wren you can assemble it the wrong way round to give you a rear facing exhaust

Wren does offer a reverse exhaust, but it is NOT the same as the standard. IOW it is NOT reversible, but a totally different exhaust.

The exhausts have been cut ready to accept the dummy air intakes . So the gasses now come straight out causing no harm to the canopy or other parts

First Flight

JOB DONE ? first flight in rather windy conditions but looks and flys great . I flew it with 800mm symetrical nhps blades but I`ve just got a set of 875mm semis from vario which should improve lift etc . heres the vid . I`ll post more once it`s finished if any ones interested .

Cheers Colin
