Yes Multiplex Royal MC and Profi 2000 looked similar, but this says Simprop and is Simprop - nice find 😀 I bought a Multiplex Royal MC radio set at the Nationals in 1985. A significant increase in functionality compared to the Skyleader TSX7 I was using at the time.

There is an OS silencer with 37mm centres for sale here: https://classifieds.bmfa.org/acadp_listings/os-3071-silencer

Thanks Geoff - very useful.

I am quite interested in building a Value Planes Tiger Moth as I have an OS GF40 petrol doing nothing. I read somewhere that the wing sweep on the top wing was insufficient to be scale. Is this the case?

I have an Angel 50S with Hacker A50 V3 motor and Hacker ESC with elevator servo (JR8231) in the tail and rudder servo (closed loop) behind the wing tube. With the battery (6s 5000mAH) I can balance at 145mm, but I believe the CofG is further aft than this to give me the handling I want. I would test fly at 145mm using lead on the firewall and then see how it handles.

Perhaps a specialised auction is the best place to sell them: https://www.gildings.co.uk/aeromodel-engines/ Gildings are a face-to-face auction plus online, so will attract the right clientele i.e. collectors.

The Spitfire looks awesome, but why such a short test flight/session?

I was wondering how many people went? The weather over the weekend was not ideal - Saturday was very wet and Sunday quite windy.

Prosynth fuel Is very much a Marmite issue. Those who use it seem to like it and those who don't use it, don't! I have used Prosynth with 2-strokes without any issues. Jon, do you use Laser 5 with 2-strokes, or don't you play with 2-strokes?

Thank you all for your feedback.

I wonder what I'm doing wrong. Out of interest: Paul do you mount/orientate the Kavan pump as per your picture?

I have used Kavan fuel pumps for a quite a few years. However, I've got through 3 in the last 12 months or so. My current pump has started to aerate the fuel so the pump rate is abysmal. Has anyone else experienced issues with Kavan pumps? What other fuel pumps are there that are potentially more reliable? Should I go mechanical? Any experience/advice appreciated. BTW I use a Jersey Modeler fuel caddy for petrol and have had no problems.

My experience with a 3w 28i would suggest 18x10 or 19x8 would be a good choice for your DLE 30. Clearly, it depends on airframe and also there are variations in makes of propeller. I tried a Mejzlik !8x10 on Acro Wot XL, but found to my surprise that a Menz S 18x10 performed better. I would use a 19x8 on the Jungmann as already recommended.

I defended myself in a speeding case (camera van) in court and was found guilty of doing 31mph in a 30 and fined £200 😞

I've bought it from ebay suppliers previously.

Yes as per ES's post I also use piece of tubing over tube to secure. Silicon for glow and Tygon for petrol. These days I use Tygon to secure quick links in preference to fuel tubing - it doesn't split/degrade.

Yes - using underside engine bolts was recommended years ago (early radio + free flight) to protect engine lugs from breaking off in the inevitable crash 😞 These days our equipment is significantly more reliable and hopefully we all crash less often 🙂

I have a Zenoah 62 PCI installed in a Toni Clark (TC) CAP 21. It uses a TC Hydromount resilient engine mount and TC canister silencer. The combination of engine/engine mount/silencer/propeller results in a very quiet aeroplane (for 2-stroke petrol). The dominant noise is propeller noise (Engel Super Silencer 24 x 10). If you want more details see: www.toni-clark.com for the various bits.

Very sad news - he will be missed by so many. My thoughts are with Alex's family and friends at this time.

Thanks Barry. I am flying full-size out of Sisteron and the nearest model club is in Ribiers about 5 miles away.

Thanks Matty. I had looked at the www.finesseplus.org and was surprised at was required to fly models in France. I wondered whether there was any reciprocal arrangement with the CAA/BMFA scheme. The risk with it being so difficult is that even sensible people will be tempted to fly "illegally". I will leave my Shadow glider at home ? Thanks again Robert.

I am heading off to France this weekend to do some full-size gliding in the Alps. I would also like to take an electic F5J type glider (NAN Shadow E) with me. Can any forum members who live in France (eg David Davis) give me some advice. Is the UK CAA registration scheme recognised in France, or would I need to the full DGAC registration etc? Are the rules different for flying from recognised French model clubs in comparison to ad hoc flying from a farmer's field? All advice appreciated. Regards, Robert

Jon, an interesting project - please keep us updated. The 300 will be about right and sound great!

Which Laser engine have you installed 300V or 360V?

I flew a Tornado (Crescent version) in the late 80s. It was powered by an HP 61 FS and then a Webra 61 Champion on a pipe. The Irvine 61 will be a good match. Any trike retracts will be suitable - Springair, Robart and Rhom retracts sometimes come up on ebay.
