Matty, Now I have pretty much all of the feedback I will get on it, should be submitted by the end of the month all being well. Rich

The Ghost Squadron uses these having been towed up by them numerous times, I can vouch that they do the job reliably time after time.

Progress so far. It’s all gone fairly well, I made a mistake of fitting F4 too high, so the cockpit floor is in two sections, schoolboy error but it does not seem to of effected the squareness of the fuselage

I got my trannie back from T9 on Saturday and, even though one cell was down at 3.13v at that time, since I recharged it indications thus far are that the new board has solved the problem. Cells have stabilised at about 4.15v with the trannie switched off, and with it switched on for about 4 hours today, they both went down to 3.84v. So, not the massive imbalance that I was seeing before.

Changed my mind about the aileron linkages after seeing an F5J Aileron linkage video by flightcomp and decided to see if I could get hidden linkages without too much slop. After a lot of faffing I got it all fitted - but there is more slop than I would of liked - servo mounts are solid, but wee bit of slop in servo link/screwed rod, + a bit of movement in the servo output shaft. next time I will use more exposed aileron horns to lengthen the lever arm. I have some IDS drives but they looked a faff to fit in this wing but the external bearings would definitely help prevent the output shaft movement.

He's already using one needing something bigger

? for 3 in 1 oil ! Horrible stuff, worse than castor . As already said its acidic and stains Ali cases badly. It also sets like a cross between epoxy and tough varnish that's hard to remove. I came across it many years ago when I bought a box of new engines that had been taken out and looked at then flooded with 3 in 1 before being put in the loft for a few years. When I got them home every one of them needed a complete strip and rebuild. In fact 8ts the reason I bought my bead blast cabinet as the cases were so badly marked . All of the bearings were ruined and had never seen fuel. Best place for 3in1 is the bin ! Ps if your bin has a squeaky lid the 3in1 might help it while passing through ?.

A wattmeter is your best friend, enables you to check that you're not overstressing the power train and enables you to compare the power requirements of different diameter/pitch props. Lastly you can estimate how long you can fly for on a given battery capacity.

We have a Bidule in our club.

Sorry, but if you are going to do electric flight to any significant degree (especially if you are speccing your own powertrains) you are going to need to roughly understand how motor Kv, pack voltage and propeller interact to give a given power level. Unfortunately you cannot just choose a 500W motor if you want 500W of power - that motor could generate 5W, 1000W (if only once!) or anything in between depending on the pack used and prop attached. It is not that hard, but a bit of reading will be instructive - the motors thread is probably the one to choose... This article also provides a nice worked example of how you might choose a powertrain as well based on motor and model specs. If you really don't feel you want to read up then that is your prerogative, but expect to burn up some expensive equipment (and possibly the models they are in if you get it really wrong - lipo batteries do need to be treated with care) along the way. Knowledge is power - ask this guy, who probably wishes he'd thought a bit more carefully about the powertrain and intallation for his 3D printed EDF airliner... ?

Big Wot 4s are a common choice.

When I lived in France we used to used a glider tug called a Bison I believe Topmodel sells a kit here is a link https://www.topmodel.fr/en/remorqueurs-C66 Hope this helps

420 mile round trip for me. 1st timer at Cocklebarrow and enjoyed the day. A week previous 'they' forecast rain. On the day it recorded 31C in the car. (an ice-cream van would have done a roaring trade.) A very relaxed friendly atmosphere. Took my Quaker Flash and at one point had trouble getting it down due a thermal lift. Both flights I also dead sticked which is very unusual with the QF. Saw an Astro-Hog so presume it is Dav S's mentioned above. Well attended, maybe because of the lack of meeting due to the pandemic, and need a bigger car park. Big thanks to Tony Tamlin for organising it.

Its all back together. Really for John S whose help last week end made a repair even possible. Not perfect but it will certainly do.

Yesterday was test flying day. I flew my new design, "Hound Dog"Which is very nice and aerobatic but needs some tweaking of the throws and trying a different props. Span 50"

Yep! I’ve been trying to perfect the technique for my next build, plus, if it’s good enough for Bellanca, it’s good enough for me! ?

Just for interest (hopefully) here is a picture of the inside of the fuselage before it was closed up underneath showing the sheeting in place.
