    Hi Brian, Just to be clear about a couple of things - there is no revised F1. The kit is not supplied with one and we do not sell one. The model is designed for electric power only. If a builder decides to build a Tiger 72 for ic power then I am very pleased but it must be understood that the model is not designed for ic engines and, like any electric to ic conversion, the builder takes full responsibility for the modifications required. A small number of my customers have contacted me to ask about ic conversions and I have supplied them with a suggested alternative F1, free of charge and on the strict understanding that it is supplied as a favour and not as a kit component. The correct location for the former would be determined by measuring the distance between the rear of the propellor and the rear of the engine mount. The alternative F1 supplied should fit in approximately the correct position but will need trimming to suit the individual installation. Hope this helps, Jim.

    Dwain, I don't mind at all - in fact I actively encourage people to adapt things according to their own preference! That way we all benefit from each other's experience and every builder ends up with a personalised model. You are certainly making rapid progress and I am looking forward to seeing the finished article!

    Looking really good Dwain! I like the choice of covering, here is the original Jemima prototype (Jemima being the predecessor of Puddleduck). As you can see, I used transparent film of a similar colour! Jim.

    Great to see you're building a Puddleduck - keep us posted with your progress! Jim.

    Hi Brian, I must admit, I have been meaning to get around to building a T72 with an ic engine but I just haven't had time. IC versions have flown successfully with 17cc petrol engines though. At the Gaydon show in Autumn, Jon Harper of Laser engines had a good look at the prototype and expressed his opinion that it would fly well with a Laser 80 or give unlimited performance with a Laser 100. The structure as it stands is strong enough to withstand the vibration of an ic engine and I can supply a replacement blank F1 from 6mm birch ply to take your engine, although it will require drilling to accept fuel lines, throttle pushrod etc. The cowl would need some adapting to fit around an ic engine but it is nothing that should be beyond the skill set of an experienced builder. Best wishes, Jim.

    That's me disqualified on two counts then - although I will have a rucksack!

    Just visiting. I build steam engines as well as aeroplanes so I'm after a few bits and pieces. I always go to these things for "a few bits and pieces" and come home with a car full of life enhancing tools!

    I'll be there on Friday.

    Posted by Peter Miller on 12/07/2017 12:38:25: I Don't agree Jim. The <20 means or less than 20 mteters the 500> is or more That was my point Peter - the symbols were the other way around at first!

    Ahem... I don't mean to be a smarty pants but you have the < and > symbols the wrong way around!

    Check with your airline but generally all lithium batteries need to be in hand luggage, not the hold. It might seem counter intuitive to have lithium batteries in amongst the passengers but the logic is that if a lithium battery goes bang in the cabin it can be detected and dealt with far more quickly than if it is in the hold. A tx with no battery in it doesn't present any risk so could go anywhere, but I'd be inclined to keep it with you anyway - hold luggage gets all sorts of rough treatment.

    Chaps, nice to see some interest in the thread. I have, for a while now, been sorely tempted to build another T72 with a two piece wing and a Laser 100 up front. If only I had the time...!
  13. Jim Newberry - Nuviation Ltd.
    I like that a lot!

    Sorry to hear about your mishap Fredrum! It's all part of the game but very annoying when it happens - especially after you made such a beautiful job of the model! Jim.

    Well I didn't manage to get any video as I was on my own but I am happy to report that it flies - and very well too! It was a bit windy at the field but I decided to give it a go and based on this afternoon's fun I would say that I'll be getting a lot more air time with this model over the summer!

    Thanks Davey. It's my own design, based on an earlier design of mine. It has a 56" wingspan and weighs just over 3lbs. It is electric powered and I would have flown it this afternoon but I ran out of time and had to go to work so it will have to wait a few days.

    Just finished my latest model this morning so I thought I'd share a few pictures here. It's called Puddleduck and it is a vintage style three channel trainer. It is very similar to my earlier Jemima model but with a few improvements. Hope you like it!

    Happy to report that the laser cut parts sets have arrived so if anyone would like one, send me a pm or have a look at the Nuviation website here - **LINK** I only have a small stock at the moment - I didn't want to overstretch myself on my first run in case interest proved to be lacking. I don't plan on posting any more updates on this thread as to do so could be in breach of the forum rules. It's been great fun building and flying the Tiger, thanks for all your input along the way. Now for the next project.....

    I like the look of the Fun Cub XL - I'd be tempted myself if I didn't have my hands full reducing piles of balsa to dust - I'm building the revised version of my old Jemima design at the moment while CAD drawings are progressing for the model after that! I may get around to trying the Tiger on 5 cells to see how it flies. I reckon it should perform well but until I've actually tried it myself I can't make any promises.
  25. Jim Newberry - Nuviation Ltd.
    Thanks Percy. To be honest, I wouldn't recommend the 4s set up at all. It needed pretty much full throttle the whole time! 5s should work better. I haven't tried it on 5 cells but I understand the static thrust should be around 9lbs - that figure is based on information from George at 4-Max, and since he predicted the 6s thrust figure absolutely spot on, I'm inclined to believe his estimates!
