Odd. I thought that was the way we all do it? Any other method would be extremely long winded.
As long as any contact is with the back edge of the prop, you should only get a literal rap on the knuckles with no bloodshed. However, not the case with a pusher prop and you won’t find me within two inches of one of them. I still have the scars inflicted by a little Veco 20 from the mid seventies to remind me!
To be more accurate I think the contact was when removing the glow igniter. Still really not sure how I got into that position as it caught the base of my little finger.

Turning while it's running, are you going for the Darwin award ?.
Main needle tuning always when running. Low speed for me is a trial and error as (usually) a bit more fiddle to get to.

They do bite and bite hard. Tuning my 70 and the thing didn’t even stop!

Sadly the weather has been pretty bad for the best part of the last couple of months so not flown for a while... but then Ive not flown anything!
After its refurb it hasn't missed a beat. We're coming into the prime conditions for flying so it will get a lot more airtime.

At the moment i am not sending the inline's out of the UK as its just too complicated if there is problem. I already sent one out against my better judgement and it turned into a nightmare for all involved. Until the testing is finished and it is a standard stock item they are uk only im afraid.
ahhhh Jon shes purring like a kitten. You were up front with your reservations and I'm a happy customer.

1 I'd love a laser radial of a size to power a 1/4 stearman or Waco
2 Please keep the singles going Great size for a simpler sport model
3 re Glow/Petrol I'm impressed by the reliability of the Lasers. I like my Saito petrols but they do have some reliability issues.
Had 2 5-6min flights yesterday with the 200i in my H9 Vans. It didnt miss a beat and probably used less than 300ml fuel (paid $15AUD for 2litres so not too costly)
Also a couple of flights with myLaser 80 powered Antic as the conditions were so nice for a slow float around the sky.

According to the construction manual
Ailerons 15mm each way
Elevator 15mm Each way
Rudder 50mm each way of a 10mm right rudder at neutral
CG 65mm back from LE middle should be 3deg nose down

Good to see another in progress. Mike, your situation is virtually the opposite of mine. I have an engine with acres of space around it. Your solution will be very helpful when I get mine in the Tiger Moth.

That looks clever. Is the inflow of air through it going to end up in front of a baffle around the front cylinder? I had a Pilot Extra 330 with a side mounted Laser 180 and simply blocked the useless side intake, though it didn’t look great even when painted black.
As per Jon's suggestion the air will be directed to the upper right side of the engine bay and exhaust psat some minimal baffleng around the engine. Left upper cowl will be blocked off hence the need for the duct.

Is that glass cloth/epoxy being applied - good idea as heat soak may affect the printed component depending on the material - it's certainly given me food for thought for improving the ducting I printed to split airflow to each of my 200v cylinders on my Tempest as I used PLA.
Martin its printed in clear PLA. I will paint with resin as its just tacked in place with CA at present. I had to flatten the side exit a little so heated with a heat gun (protecting the cowl with cloth and hope!) managed not to melt the cowl. I cant take credit for the CAD enlisted my enginering student daughter to do that.

I printed a cooling duct to take air from the left side intake

Hi Ted. The wire wheels look really good on early planes. Did you buy them or are they part of the kit?
I was given the wheels by a friend leaving the hobby. I suspect they were Topflite but cant be sure. I built form plans but I dont think the kit (if you can get one) includes wheels.

it was at my request Ron give filters a try. The debris we are talking about is quite chunky grains of very sharp sandy material and they are not the recommended diet for anything mechanical. Also as we are trying to test this engine for reliability, external damage will not help us!
Beyond that though i have been thinking of recommending filters for some time as the two most common types of damage we see are bearing corrosion/failure and debris ingestion. Both of these are more common than crash damage when it comes to engines on the bench for rebuild.
The reason is simple enough. How often do we clean out the engine bays? not often i would wager, and certainly not after every nose over/trip into the weeds at the edge of the strip. All of that sort of thing accumulates dust and grit in the cowl and eventually it will find its way into the carb area. My poor Hurricane needs its face cleaned up after a belly landing last weekend. Its a chore, but i dont want to have to pay the boss for new engine parts!
Word of warning be very cautious with a filter, pre flight check. Once had my OS90 heli engine suck in the foam mesh of a filter mid flight the sudden stoppage of engine sound was not good! Scored the innards pretty well. This was one of the rubber boots with a plastic ring and foam inner.

My newly maidened Antic powered by a Laser 80. Built from Proctor plans with a few tweaks. Video of the first takeoff and second landing.

I took delivery of the CR6 last week. So far it’s been simple to assemble and prints have been good. My daughters hogging it at present printing a chess set for her boyfriend but I managed to do a test pilot.

Ted, smashing. Out of interest where did you get the plans from, as I see its a US kit.?
Bas
Thanks. A friend gave the plans to me not sure where he got them. The plans are very detailed. I have a Proctor Jenny kit waiting to be built and this was my test run in learning the Proctor way of doing things. Mainly handling the thin ply and spruce. There’s very little balsa in the build.

It almost seems a shame to cover it up Ted.
Is that the tail of a Bristol Monoplane I can see hanging on the wall behind?
It’s a Blackburn monoplane handed on to me by a former club member to complete but other things keep getting in the way.
I’m covering in Antique Solartex so some of the structure will be visible in silhouette.

Not quite ready to fly but I like the bones. Proctor Antic built from plans powered by a Laser 80.

Jon please tell me the 160 is also anodised ..... that 200 is the ducks

Jon, since you’re considering taking orders for the pre production engine, would you also consider taking orders for the existing range? Perhaps in batches so at least you then have a target to work towards. I know you don’t want to have people waiting long periods for an engine but some of us (me!) may be happier in the knowledge that we’re in the queue.
Just my take.

Thanks for the posive comments.
Trevor you're right wrapping the Rx is a hangover from the old days. I now dont wrap the Rx and will change this when I next dismantle the model. It stays assembled 99% of the time as it fts in the car fully rigged.
Chris, your mate has done a great job. Scale models look so much better with a pilot.
Look forward to more progress

Mine stays assembled. Fits in a Megane three door with the tongue just so. It’s Saito powered and has a removable hatch in the floor of the engine bay to access battery and another over the engine for maintenance.
Laser 70 Carburettor orientation.
