Is this a long lost crate of old production, or brand new metal coming out a re-opened line? sanyeengine.com website is alive - kind of - and seems to suggest the place getting back off the ground in 2021 (!)

Brian has fine advice in his post. Just a little extra speed can work wonders - it doesn't need much to increase elevator authority at the key moment - don't be afraid to feed in a dab of power, to control the rate of descent at the critical moment and to help with flare out.

I usually do 1/8" "ribs" and 1/16" sheet either side. Reasonably light, more rigid than open frame, YMMV as ever. Chilli has a nice long snout which does not suggest it will be difficult to get the CG in the right place. IME (several IC incarnations of the Breeze, IC and electric conversion of the larger one) the CG was not a problem.

Just going to ask the same question. Only thing i can really think of at this point is damage to rx. The servo monitor has told you the tx is sending something to the unresponsive channels.

Crikey, i wish my build projects were this quick. I can't knock out a tailplane in the time it's taken you to do the entire airframe. Nice work!

Os 40 fp Simple, reliable, excellent power/ weight ratio. Best engine os made for a long time. Irvine 36 Best of British two strokes Os 46 & 61 sf Second best of os two strokes, beaten only by the fp. Recently, os alpha four strokes. Have run several sizes and all have been lovely to use. Dare I say it better than the surpass engines.

There's a place advertising laser cut wood packs for the Flair scout series. Perhaps it's too late. But if you got your money back... laser cut wood https://skyhighrc.co.uk/flair-puppeteer-rc-scale-model-aeroplane-laser-cut-balsaply-rib-sets and plans https://www.ebay.co.uk/usr/flyer21uk and hardware from Inwood https://www.ebay.co.uk/itm/202467876433?_skw=flair&itmmeta=01J8SSNR625ZK498PRHSZ75YJ6&hash=item2f24069e51:g:T00AAOSwpd1hf~j7

or use your charger to do a discharge/charge cycle (fewer airframes involved etc etc) in reality, if they're still showing a decent level of charge, then they're probably just fine

good shout a liberal dose of contact cleaner is due, perhaps

remember the engineering mantra hoochy, "close enough's good enough" the trick is working out what 'close enough' is 😄

JD I think 4 strokes not only burn some of the oil but they're also less thirsty in the first place. Win win on this front. martin, you'd want to go one size up from the 52. The 70 surpass would be ideal i think, if you're looking for a second hand motor, or the newer 62 V is nearly the same power but a touch lighter The 60 something saito also feels about right. Two stroke glow, they don't burn any of the oil, it's all going out the back. As has been already posted, an extender can get most of it clear. But how long does clean up take though, really? Five minutes? Ps confirmed glowphile here

Graupner super nylons in both sizes - I'd always considered them relatively heavy props.

I found similar with the 40 Surpass, 11x6 was ok, did have one or two thrown props, it seems happier on a 10x7 or 11x5. The 40 only has the simple air bleed carb.

https://www.ebay.co.uk/str/root729uk 6 channel £17, doesn't get better. I'm somewhat sure you can remove the cases? The Orange R615X is out of stock at HK UK store, but in my experience is just as good. Also removable case.

If that was using torque rods on a low winger, then some forward rake of the horns (as in, the torque rods themselves) is correct for that setup.
