Sounds like you have a keeper there. Well done.

Regarding the mixing of down elevator with throttle. I have used this in the past but I programmed it to come in progressively once it got to about half throttle. At lower power you shouldn't get much pitch up. Initially climb away from hand launch with about half throttle and then open up on the climb out.
That should prevent any issues on launch.
Thanks Lecky. Sounds like a good plan. I shall put a pic up once I get some trim on it and shrink the film better. Its certainly a keeper, Stans kits all fly well but I was uncertain of my own ability with electric to convert it. Thanks to Patmac for the perfect combination of parts, it works!

Snap !  ;)

Bob, have you tried moving the cg back as far as is comfortable ? Makes a difference to the nose up pitching on power, reduces trim changes when inverted & improves glide.
Not yet. It's exactly as Stan puts it but I will play about with it if we ever get any weather above three degrees...

Beware using a down elevator mix with throttle, you can end up with flying into the ground on launch as the elevator works before the motor effect kicks in. Possibly better to use your thumb instead.

You could do it if you can programme the down elevator to come in a couple of seconds after the motor start.

Better to adjust the downthrust if you can.

Just a thought.

Bob, the climb's pretty well vertical, get's uncomfortable to see within a 15 -  20 secs. A lower kv motor & using a bigger dia prop would climb faster for the same power. I nearly always fly it at full or closed throttle doing aeros on the glide.
If you use down elevator compensating mix with throttle it's best to set a second or so delay. I didn't first time I tried the mix, dived from altitude on the glide for a low fast pass down the strip & opened up ready the climb back up but the down elevator mix took effect before the throttle & nearly caused an embarassing nose dart manoeuver.  :embarassed: Since then I've moved the cg back to minimize the nose up on full throttle & on this model I manualy control any nose up pitching instead of using a mix.

Thanks Max. Never thought of that. Don't want to alter the thrust line now as it looks spot on with a nice fit fuselage-spinner. Probably just live with it, the idea is to climb and then use the height for manoeuvres after all. I'm quite chuffed the thing works and is far better than buying some foamie to do the same job.

Hello All,

I'm new here... I'm Dutch but live in Belgium. Born October 4 in 1949. Happily married to Monique. We have 2 sons and 3 grandchildren.

Presently retired I've been working over 36 years in Air Traffic Control and prior to that I studied engineering on both airframe and reciprocal engines and got my hands greasy as well.
In other words airplanes have been my livelihood.

I'm totally hooked on Scale RC-Modeling. Have been since 1980. Approx 1985 I paused due to other priorities in my life but have picked it up again in 2014.

My current project consists of a giant Jerry Bates 1/4 scale Hawker Fury FB10 i.e. without collapsible wings. Well that keeps me busy as you may imagine...

I'm glad being a part of RCMF. Thank You!
Also i'm open to any help, questions or otherwise, anyone may wish to call upon. Likewise of course I shall be glad to receive help where needed.

One is never too old to learn. ;)

Kind Regards,

Jos Frusch (jossurf)
