Hare is a bit of onboard video from “Abigail” today during our one and only race.
There was a lot of weed floating about & not much wind but we managed.
Had a good turn out even with the less than ideal conditions.
Finished off the day with the customary Lunch Time BBQ then headed home just as the rain decided to return.
Personally I reckon you should have won Kermit, just for capturing the jumping fish, perfect timinh!!
Maybe you should have highlighted it with a bit of your infamous “Slo Mo”. It may have been too quick for the Moose to spot?
Got around to repairing the RHS undercarriage on the Super Chipmunk today.
It turned out that the anchor block in the RHS wing has come unglued (I wondered what was rattling around inside the wing when I first got it from my friendly little frog Kermit!!).
Sounds like there may also something rattling around in the LHS wing as well.
Given the end of the wheel strut had no anchor block it only took a very light bump to fold the wheel back and cause the nose over on landing, & I thought I was going well on the landing approach & wondered why a relatively light landing caused the failure . Now I know.
Needed to cut a hole through the Balsa wing covering to access the inside and glue the anchor block back in place.
I’ve fitted a temporary patch to the wing until I see if it works OK, if not then I’ll remove the balsa cover sheet completely from around the undercarriage & rebuild the landing gear mounting inside both wings then recover it all.
Till then I think it should be OK to test fly again on Friday (or whenever we next go).
Other than the landing gear issue she flew very nicely (once I dialled the throws back a bit).
Won’t Hoppy be pissed, been waiting for weeks to fly float planes and the weekend the paddock finally floods is the weekend he heads off to Qld.
Oh well, Kermit has a float plane so we may still get some water action.
Your video is working OK now but not before.
Anyone can copy the link to ANY public video on YouTube and re publish it.
Well the first flight of the Super Chipmunk did not go as well as it should. The plane was way underpowered with the 14 x 7 prop only pulling 320W @ 20A.
I have replaced it with the 17 x 8 prop from the Grand Tundra and it is now pulling 640W @ 44A so that may well be enough. Both the Motor & ESC are overrated with the online info suggesting a 400kV motor & 60A esc are all that is needed.
No doubt next flying day will see.
Another quality production Mr Kermit however for some reason you are only publishing in 720p rather than 1080. Significantly reduces the quality of the video especially when watching on a large screen.
Plenty of Crash & Bash action to capture this week.
Just lucky no one did any major damage.
Moose, one thing I found online was that large slow powerful motors really need metal engine mounts. Prolonged running generates significant heat & timber or plastic mounts tend to fail when they get hot.
The Chipmunk has a full metal mount all the way from the firewall to the motor. One section bolts to the firewall and the front section that holds the motor is adjustable via 4 bolts (two each side) so the up/down and left/right angle of the motor is easily adjustable.
If you cant find one on line then I’m sure one could easily be made with some aluminium plate.
Here is a link to one similar to the Chipmunk, for the price its not worth making one.
This one is by far the cheapest (from AliExpress) but eBay & Banggood also stock them, just a lot dearer.The Super Chipmunk is finished & ready to fly.
The Motor is a Turnigy Aerodrive C4260-500
and the ESC is an 80A Flyermate capable of using 2S to 7S LiPos
Some online info suggests the plane needs a 5S or even a 6S LiPo but other posts suggest a 4S is fine.
The plane has a purpose build battery hole in the underside and given that a 4S 4000mAh (ex Grand Tundra) is a perfect fit and gives a near perfect COG that is what I’ll try.
The motor has been lubricated & all fixings locktite’d, the wiring tidied up with XT60 plugs instead of the old Deans connectors and a new receiver & Hobby Eagle A3-V2 stabiliser installed & programmed.
Hopefully Tuesday or Wednesday will be good to fly so won’t need to wait long to try it out.
Think I have found the issue with the Slow Poke Max Speed being lower than expected, the AeroStar 40A ESC is faulty.
Was doing a bit of testing today and it got far too hot to touch and the motor was running very rough.
I’ve installed a Turnigy Plush 30A esc and all seems to be running fine. WOT on the bench is 28Amps so I should be able to get away with the 30A instead of the 40A
I’ve put a warranty claim into HK as all except batteries is supposed to have 12 months warranty.
Next project will be the Super Chipmunk.
