HK 30cc Sbach, powered by a Laser GA30



Thread: Forum members' new models: Let's see them.
23/04/2019 18:22:23

I bought this unmade HK Sbach a week ago and was going to power it with one of my DLE 35s. I then decided to fit a Laser GA30 petrol to see what it would be like. First flights today show that I made the right choice, not a true 3D machine but can perform scale aerobatics. First flight required 2 clicks up and 1 right aileron then flew hands off. Second flight was cut short as it developed a pronounced nose down attitude so thinking that something had shifted position I landed and discovered that an elevator servo horn had stripped its teeth, lucky escape for me! Thought that was the end of flying but later in the day a pal came up to fly and just happened to have some spare servo horns with him. 10 minutes later all fixed so ran the engine up to temp then noticed that on full throttle the elevator half’s were waving to me, in opposite directions, not a problem at lower throttle settings, just when in high. Couldn’t see anything that would cause this but decided not to fly! Anyway, here are some photos.

Due to this thread I went in to see my doctor last week to see about a test, I thought the last one I had was about 3 years ago. Turns out it was 7 years ago so I’m going in on Tuesday for another!

Are those aileron servo boxes in the wing, if so the torque rod won’t be an issue?

You could always put a slight delay to the throttle cut, this plus audible warning gives time to switch back to normal. Not ideal as throttle cut is usually instant but is a, say, ½ second delay that big a deal?

Nowt wrong with overkill Chris!

Hi Chris, I’m in and would be looking for 4 boards. When I’ve had thevsmaller FrSky RXs sent to me from T9 they just come in small Jiffy bags inside a padded envelope.

Put a cloth / towel on the foam before pouring boiling water over it otherwise you may well get the dreaded alligator skin effect!

Connect a bit of fuel tube to the vent pipe and have that in a small fuel bottle to catch any overflow, keeps the site clean!

The NGK replacement is the BMR6F, Just Engines sell both these and replacement plug caps to suit. £15.50 for the pair!

I'm with Bob on this one, a favourite of the month and try and rotate the (far too many) others. But its only natural to have the latest build or rebuild as the flavour of the month.

@Bruce - no readings I’m afraid but am just about to build an SBach for the 35ra so will be testing it in a couple of week’s time (the 35s are between ‘planes at the moment!).

@Bert - good advice Bert but most tests have to be conducted at WOT. Maybe a mechanical throttle stop would get over that issue?

Whilst I haven't gone that small with gassers, my DLE 35s and 55s run a lot quieter when fitted with a can, it's the volume of the 'silencer' that makes the biggest difference!

Yep, hot glue works good!

A flying buddy had one of these, flew really well but you had to be careful on landing as the u/c is not that strong. I would suggest landing on the hard stuff but watch the overrun onto grass!

Grand Tundra, brilliant 'plane, although somewhat bigger than my Funcub.

Grass could do with cutting Andy cheeky

That Typhoon looks rather nice - good job done there.

Hmm, not too sure about feeding breather into intake as oil from breather will alter fuel mixture. I would always try and vent to out side. Of course some manufactures design the recirculating system presumably so their users see less ‘mess’, still don’t like it!
