happy birthday to you ,happy birthday to you happy birthday 1/2 nut. happy birthday to you

Hey all its Brad,

I wanted to thank you each and everyone of you for giving me such warm wishes on my birthing day

Lovely picture of the hottie on the mustang thank you Eric and colorful icons gave me a smile

Hard to believe another year has gone by wow wow so many ideas for projects and so many not done lol!!!!

I have been working on an engine on my birthday enjoying Saturday free time yessah!

Balogh still working on the Skorch II will post more soon.

With Randy's help from Mecoa a package came in the mail today on me birthday so doing yet another car engine conversion (Picco P-zero .05) so I can have some backup engines for the larger Skorch II project.

Tested a new in the box old stock AME .061 last weekend with the 1/2A Skorch:
Vid is HD 60fps ideal for showing actual speed. The Norvel allowed
excellent acceleration and thrust for the first time on a 4.2x4 this is a break in flight
only 2oz of fuel ran on the bench prior o the flight. on the third flight it topped 28k+
28,238 rpm / 107 mph - new bench mark happened about 5 mins into the flight
The AP Wasp .061 needed the 4.5x4 in order to make the same thrust.

The high performance crank is subject to breaking some have reported breaking them running past 30k. Larry came up with a solution to protect the crank. For me I just bought a Sportzwerk crank same size and fit and not so thinly bored out some loss in rpm. I plan to keep it under 30k and enjoy the quality of the engine and only flip start.
Shown with a APC 4.75x4

All done .052ci .85cc engine stock rated for 35k rpm.

Went with a AP .09 carb

Thank you Eric,

Yea I should get some life out of it as long as I dont over prop as the cranks can snap if pushed to hard.

Here is a weight check with the stock Mecoa parts, AP 09 carb, 4.75x4 prop.

No I don't the only thing I have is his address on the box he sent me and of course the contact info used on ebay.

Under the circumstances here is his physical address his phone number may be listed;

ALBERTO CABALLERO
domingoe@msn.com

Lazy Land Mobile Home Park
4111 SW 25th Street Lot 103
Fort Lauderdale FL.
33317

He doesn't list his phone number I checked, your best bet is to email him on MSN he would check that
more so then ebay if he doesn't have any current stock on hand. He has told me he places large
orders in bulk when he buys then sales only on ebay. I sent him an email tonight as I want a few more
spare pipes one for bench testing one more for another plane project. I only have two and that's just
not enough lol!!!  

Thank you Jacob
