There is a link to Venom's website at the bottom of the page you linked. The manufacturer recommends this under the 'hop-ups' list on the plane's web page:

You can try this for $15 less, or even get the special, two for $88 so you have a backup:

Or this, for more mah:

Was going to suggest that Venom's site has the same plane for $20 less. If you get it from Tower you can ask the tech's questions about what will work, and if something doesn't work right it will be easier to deal with one store with great customer service. Also will probably save you on shipping.
