Wow... I guess the prop bolt / spinner orientation isn't important to where ya "Flip it" !!!

RE: TA 152H Meister Scale Project Grun 4
 

set the prop up at 3oclock and 7oclcock

RE: TA 152H Meister Scale Project Grun 4
 

Will do.

RE: TA 152H Meister Scale Project Grun 4
 

perfect the concentric forces applied to the bent prop
will flatten it out at speed, and all will be good

RE: TA 152H Meister Scale Project Grun 4
 

Going a little slow since this motor, prop and spinner is more than my house payment. I first machined a 1/2" long shaft extension from cold rolled steel and tapped for a M5 x .8 cap screw.

RE: TA 152H Meister Scale Project Grun 4
 

Carbon prop was drilled using a DA-85 drill jig and the old masking tape trick. I also flipped it over and repeated the drilling on the reverse side.

RE: TA 152H Meister Scale Project Grun 4
 

I've learned the hard way that it's VERY important to NEVER use a drill press to open up the center hole on these heavy duty back plates. The center hole was painfully hand reamed. Bolt holes are drilled in the back plate and everything mounted. Wheeew! That was stressful. So easy to mess things up at this stage. Drill the wrong hole in the prop jig, stripped threads, you name it.

Everything so far is perfect and the back plate turns true.

Will be working on the throttle and choke linkage next...

RE: TA 152H Meister Scale Project Grun 4
 

you setting the choke linkage/servo up with a switch on the transmitter?

I think this is the new Hacker Hybrid motor. Sorta like a Prius.

RE: TA 152H Meister Scale Project Grun 4
 

LOL

RE: TA 152H Meister Scale Project Grun 4
 

Been head scratch'n... I lifted up the Hacker using balsa and cut a the cowl to slip over it. This gives me the stand off distance needed to the back of the cowl.

RE: TA 152H Meister Scale Project Grun 4
 

Got the spinner bowl cut with 1/16" clearance around the Mejzlik 27-12TH carbon prop. I have 1/8" clearance between the back plate and the cowl.

RE: TA 152H Meister Scale Project Grun 4
 

I added the standoff length needed to the back of the cowl + the length to the firewall and came up with some sheen drawings.

RE: TA 152H Meister Scale Project Grun 4
 

Started sheen'n... The metric cap screw heads will have to be cut off as there is no clearance between the motor mount and the can.

What are we doing for a muffler?

RE: TA 152H Meister Scale Project Grun 4
 

I would like to suggest a Borla or Magnaflow if you are concerned about performance.

RE: TA 152H Meister Scale Project Grun 4
 

just an open exhaust

RE: TA 152H Meister Scale Project Grun 4
 

So pretty much just "Straight Pipe" it right?

RE: TA 152H Meister Scale Project Grun 4
 

I straight pipe all my engines

RE: TA 152H Meister Scale Project Grun 4
 

Now is a "ONE OFF AIRPLANE" or will a kit or conversion semi kit be avalible? Through Meister scale??
Looking great so far.Thumbs up on the ELECTRIC POWER !!.

RE: TA 152H Meister Scale Project Grun 4
 

Just some Sheen'n stuff... Not sure how the pros do it. I got this little spring loaded tap guide and some Tap Magic. No broken taps!! YEAH!!

1. Drilled for 50% thread grip.
2. Apply a drop or two of Tap Magic.
4. Hand twist about 5-6 turns.
5. Remove tap and clean out chips.
6. A shot of air in the hole.
7. Repeat steps 2-6

RE: TA 152H Meister Scale Project Grun 4
 

are you planning on using a fuel pump somewhere?

RE: TA 152H Meister Scale Project Grun 4
 

DBAD... Pandi's gonna get us.
