Nelson Q 40 engines
Well thanks to RC Universe I was able to get a used Nelson 40 and then contacted Porformance Specialtys to get some needed parts such as Props Muffler mount and plugs now to the meat of this note yesterday I went to our speed tryalls with the untryed plane and moter and found that a standard glowdriver dont fit the nelson plugs I havent contacted Porformance yet as it is sunday but does every thing about plylon raceing have to be so different and not in the main stream of things I must admit that moter hauls, mater of fact it was to fast for the plane I kit bashed together seems I'll have to buy a whiplash or dominator as I cant afford a Miss Ashley well good luck everbody and have fun.19300 aint a bad RPM on a first start with a new engine thanks again Nelson for a great product.Signed Ray Rusaw Juneau Alaska

Darrol Cady sells a good glow start clip for Nelson enigines. You can see them at www.darrolcady.com
Also, 19,300 is quite a bit low for that engine. You want to prop it into the 23,000 - 24,000 range.

rpm
I started with 7.4 inch props and had to cut them down quite a bit to get to 23,500 which is the reccommended rpm. I was using the carbon fiber props. I use the darryl caddy glow plug lighter. Its great and lets you know condition of plug as well.

7x7?
It should be doing much better than that with that small of a prop. I am at 7.2x8.5 and 23,500 on the ground. Do you have the q40 with the side exhaust and standard nelson muffler or do you have some sort of pipe on it?

Nelson Q 40 engines
This is the APC CF prop that most people are using on the Nelson Q40 engine (In fact its the only one thats legal in a sanctioned race) 7.4x8.0
If you are lucky and find one of these that is labeled (7.4x8) instead of 8.0 let me know, I would be interested in buying. They turn up a little better than the 8.0 and are slightly faster overall.
