Happenings Sunday 02 December 2018


A few things have happened ..

1st / Got me a Phoenix 1600 from Hobbyking - Was cheap ! ..
Had to replace the motor as the original cooked really well .
It's ready for some decent weather .

2nd/ Got me a HK Mig29 - Foam board Mig
Put my 64mm EDF in it and the EDF promptly went pop during a extended engine test run .
Was buttery smooth before the pop , then ran like a washing machine .
I tried to balance the EDF again , but ??? Looks like I need to take it out again ..
Ran smooth outside the model , but as soon as it went in , too much washing machine action ..
The HK 64 EDF me thinks is just too soft / flexible ..
Needs sorting out ...

3rd/ Broke my Whipit !
I kid you not , the pod broke in half ..
Me thinks strengthening the wing and giving it a peg just transfered stress to the pod .
Broke close to where the carbon boom ends ..
Fixed now ..
Glued the pod back together , then used the laminating film on it ..
Got rid of the hatch , now covered by laminating film .
Also put more lightening holes in the plastic nose cap .
Whip now weighs 47.6 grams ..

4th/ That foam safe glue ( insta cure ) is slower than 5 minute epoxy to cure .. ( PITA )

5th/ There will be a 4th part to the Jumper T12 ..
I ordered a Lipo I hope fits really well ( I hope )
Should be here on the morrow .
Then I can do a short squirt on the battery and hopefully do some range testing .

6th/ The Ripit glides ..
1st time out I broke the foam nose cone ..
Was a little tail heavy so I used the laminating film on the nose cone ..
Might be ok .. seems to glide ok . ( Not there with the whip , but that was never the intention - this was a practice build )
The next micro DLG will be balsa and will be a more serious attempt at a local park friendly DLG .

Still waiting on stuff ! ( Aint it the way )

Instacure refers to the use of kicker to activate.
Do you not use activator?
It is not heavier.
Only use medium oderless on foam as the thin may harden the foam too much when activated.
The thick and thin oderless versions build my lightest and fastest in the world speedmodels.

No - I don't have activator . ( Maybe I should )
Heavier ? - Don't know about that - but certainly did add weight .
Hmm , this would be the thin stuff , so if it soaks into the foam and hardens it . Might explain the weight gain .
