Bearing in mind it's an aerobat do you guys recon an 020 will have 'The Minerals' ?
I've got PeeWee and TeeDee 020's which would both be throttled or should I just bung a sure start up front?

Dont go for anything bigger than a TD .020 on the aerobic , they are quick on a TD 020

With the rainbow,as long as you are running 25-30% nitro it shouldnt be underpowered as long as you lean it out well, 30% nitro is good , ive always used 30% and never had a problem with wear as long as 20% castor is used

If you want more speed , try 1/16 balsa under the back of the wing, this speeds it up a lot, models i design ( such as the dipstick ) have much lower wing incedence than the ones Peter Kent designed, the Rainbow is a Miniature Aircraft Factory kit that we bought when we took them over, i prefer to raise the back of the wing a bit on his designs

My first mini rainbow had a .5cc diesel on it, that was quick

What WS was the one with an AE .5cc?

I'm being a bit thick..
Are we lifting the trailing edge where it sits against the fuz?

12 inch, fitted with hitec 101 servos gem 2ch 27mhz rx and a 250mah nicad pack , weighed a lot! but the AE.5cc diesel on a 6/3 pulled it great and it flew in any weather

I cut a slot into the front bulkhead and fitted a 1/8 inch ply engine plate, cut a hole in the top sheeting and dropped in a 10cc tin tank for the engine

It was all covered in tissue, gave the wing a lot of strength unlike film

After its built and covered i stick a piece of 1/16 * 1/4 balsa strip , just a bit wider than the fuselage under the rear trailing edge, i just pop it in after the wings are rubber banded on , maybe start with 1/32 inch first time and see the difference

I've had several calls in the last few days from guys want'ing rid of stuff from their attics
amongst which is this,-

It's wing span is 55 ins weighs 585 grams (about 21 oz in 'old money') with it's esc and motor.
Will it fly with a sure start/texaco type thing?

Two questions.....

1. Why don't I ever find people who want to get rid of stuff like that!!!!

2. Why does that model look like a character out of "Cars"?

lol!

!000 apologies Will.
I had the Mota running much better today (not quite as cold) and it was a spritely little rascal.
Very Happy
