Congratulations on an excellent purchase . The RR version will save you all the hassle of assembling the kit and choosing components. I went the same route with another MPX product (Fun Cub XL) and it works perfectly. Do let us know how you get on with the Funray. With the RR version there ought to be nothing to stop you maidening it tomorrow . Have fun!

I am now on my second Funray (I managed to destroy the first one due to my own ineptitude but don't tell anyone !) and can thoroughly recommend the model. I had no hesitation whatsoever in buying a replacement. The RR version is now over 400 quid which I feel is rather pricey so I opted for the 'kit' version and sourced my own motor & electrics etc. (YEP 60A ESC, SK3 GliderDrive 3858 4.6 840Kv and some 12.5g/ 2.5Kg servos). Choosing this route saved around £150 compared to the RR version. Using a 4S 3000mah LIPO and a 12 x 6.5 folding prop gives about 750W and, as Capt Kremen says, allows 30 minutes+ flight time. Soldering your own green MPX connectors is definitely a fiddle...…….I would be inclined to buy the premade harness (circa 25 quid) if I was building another one. The quality of the kit really is excellent. Everything fits together and, unlike so many other models, I didn't need to fettle anything. The surface finish of the foam is superb. The model has a broad performance envelope and, at one end of the spectrum, will stooge around at quite low speed and at the other end it is both acrobatic and fast (warmliner rather than hotliner but still plenty quick enough for most). It even makes a lovely whooooshing noise as it zips past on those low passes!! My canopy has never shown any inclination to come loose but Capt Kremen makes a very valid point about the potential for this to happen. The only non-standard mod I have made is to add some bright pink vinyl panels to the underside of the wings to assist with orientation. This colour, although rather garish, does really contrast sharply with the standard black and green. Feel free to PM me if you want any more info .

Looking at the comments on HobbyKing I see people are using 17 x 8 with an 8 cell Lipo and up to 20 x 8 on 6 cell. Whilst I tend to take some of these HK postings with a large pinch of salt it would nevertheless suggest that 18 x 10 is probably in the right ballpark. How many amps are being drawn with the 18 x 10? HK say the motor is rated at 90 amps max. so as long as you aren't exceeding this figure all should be well.

Yes Martin, your summation is spot on. Although I had 'trained' my YEP ESC to recognise the full throttle range it would seem that the brake-on position was still some way below the minimum stick position. Moving the throttle trim down a few clicks sorted things out. It was just by a lucky fluke that I discovered this trick.

Hi Quaddra, I had exactly the same issue with a YEP speed controller supplied by HK and tried everything I could to get the brake to operate. I used the correct program card but nothing I did could persuade the brake to work. Then, by chance, I found that moving the Tx throttle trim down by 10-15 clicks sorted the problem. I assume that with the trim at its usual mid point setting the ESC was 'seeing' the throttle as still being slightly 'open' and consequently wasn't applying the brake. So, I suggest you move the trim down towards the bottom of its range and see if that makes any difference. Good luck!

Orange RX3SM Mounting for Flying Wing
John Roberts 9 replied to EvilC57's topic in Gadgets and Electronics
Hello, I had exactly the same issue with an Eagle Tree Guardian mounted to a Tek Sumo flying wing. The solution for me was to turn the pitch potentiometer adjuster (aka 'pot' or 'gain' ) using a small jewellers screwdriver. I needed to turn mine by about 180 degrees which ought to reverse the direction of travel of the elevons. You will then probably need to fine tune both pitch and roll pots to your liking. I have mine mapped to a rotary control on my Tx so that I can adjust overall gain whilst flying. I hope this helps. Edited By John Roberts 9 on 15/03/2018 12:25:09 -
Using laminating film to add strength is now quite common practice with foam flying wings. Crash Test Hobbies have some helpful instructional videos demonstrating the process. Check out their 'Brick Wall Test' for proof of its effectiveness!

Thanks for the replies . I think I might keep my eyes open for a decent quality secondhand combo. There are some super-cheap new packages on ebay but my spidey senses tell me they are likely to be junk but I don't want to spend too much to begin with. I would prefer initially to 'dip my toe in the water' and see how I get on.
-
Can anyone recommend an airbrush & compressor combo suitable for a complete beginner please? Is there, for example, a starter kit that includes everything needed to get started or would I be better off buying 'separates'? At this stage I am mainly interested in being able to spray complete airframes rather than doing detailed, intricate artwork although, depending on how I get on, I might want to develop in this direction later. Thank you.

Very annoying & frustrating when a supplier messes you around like this. Personally I would now be at the point of contacting my credit card company and asking them to recover the payment. You can demonstrate that you have taken all reasonable steps to prompt the supplier. On the (thankfully very rare) occasions that I have done this I have found that the goods often turn up a couple of days later (suppliers *really* don't like charge-backs by the CC company) or you get your money back. Good luck! -

John Roberts 9 replied to Kevin Fairgrieve's topic in The 2014 Mass Build
On a grey Dumfries Sunday morning it flew! Even with quite modest control throws it proved to be very lively on the sticks and required a generous dollop of expo to calm it down. I have also added a touch more downthrust too (yet to be tested). Even at half throttle it is fast and borderline insane at full throttle but it is also very happy to potter along at gentle canter too. -

Well it finally got finished! Hoping to maiden it tomorrow. All up weight with a 2200 3S installed is 800 grams. I decided to make it a belly lander in the end, hence the top mounted aileron servos. I found that getting everything neatly packed into the tiny space available (especially with such a relatively large LIPO) was pretty challenging. Even with the battery pushed as far back as it will go I still needed to add 20g to the tail to get the CoG right. I still have to sort out the cowl but that can wait until after it has been test flown. There are a few more photos in my album. -

Phoenix Model Kits G-Buster
John Roberts 9 replied to John Roberts 9's topic in All Things Model Flying
Hi Richard, Thanks for the link. It does indeed look quite similar. Although I have previously built from plans I haven't tried 'scaling up' before. Maybe something new for me to learn once the cold dark nights arrive! Thanks again, John -
Phoenix Model Kits G-Buster
John Roberts 9 replied to John Roberts 9's topic in All Things Model Flying
My Google search did take me to Phoenix Model Products but I couldn't find anything like the G-Buster listed and so I assumed that, despite the similarity of names, the kit probably came from somewhere else. Thanks for taking the time to post the link though Steve. Perhaps Mr. Whittaker or the model owner, named as Graham Leatherman in the article, might (hopefully!) take a peek at the forums and enlighten us. -
Good Morning, Does anyone happen to know if this kit is still available and if so where from please? My Google search didn't produce anything that came even close. Thanks, John

Hi Sparks, Thanks for the very fast response. Zero degrees incidence for the tail it will be! Do post some pictures of your completed Mini Jazz. Thanks again. John
