Any advice from my wise old friend, Manticore?

I agree on Manticore trick of the soldering wire. Try it and your chamber height should be about 0.38mm and 0.43mm (measure the crushed part of the soldering wire with a digital caliper).

If you run on very humid places I would go up to 0.45mm of chamber height (just to accomodate the extra moisture on the air).

BTW: How much nitro? How is your weather (Hot/Cold, Dry/Humid/Very Humid), How much height over the sea level?

I would go with a 0.3 plus a pair of 0.1mm shims (total 0.5mm on shims). If you use Turbo plugs go with a 6Tf (normal plugs go to a Nova #6 straight).

Control the temperature of your engine with the low-end needle (if it overheats, enrichen the low-end, if temp is OK lean a bit and continue testing).

If engine bogs at low-end try to paliate with the spray adjustment (screw it about half turn each time and readjust low-end needle). What we pursue is to paliate bogging making the transition from low-end needle to high-end needle at more rpms. Will need to readjust low-end needle each time you will touch the spray.

This weekend I ran with more than 40ºC and needed to go very open on the low-end needle (1 1/2 to 2 turns more opened than the normal conditions). Needed to remove 1 shim to paliate low-end bogging. Normal engine temps were between 110 to 125ºC.

15/48???? Uhm... too short, unless you are deciding to do some trailering with your MTX3. :weird: :weird: :weird:

www.speedtechrc.com has good prices on the MTX-3.

I got my MTX-3 from Steve, and he's great to deal with.

As far as radios go, I would suggest spending an extra $40, and get the M8 ( $190 radio & module only ). If you are getting such a high quality car, you don't want to skimp on your radio. :)

cheapest I've seen

As far as the radio, go with the FM Airtronics MX 3. They are around $110.00

Here is the cheapest place I have found for and MTX3.......

I have dealt with Steve at SpeedTech in the past and he is a very good person to deal with. And as for a radio, I would have to agree taht you shouldnt get cheap on the radio system you are going to use. I have use Futaba all the time and to me it seems the best. Especially if you get a 3PJS or the 3PK, cause the radio comes with it own bulit in Failsafes. Which to me is a must have when dealing with such and expensive car.
