Here is the RC Informer flying video. I think that maybe RC Informer is now part of Horizon Hobby?
Manual
Good English and easy to understand. Very useful surface throw information, and the CG position has been confirmed as good.
Click here or on the image to download a PDF file.
There are 28 pages, but a quick scan will show you how easy it will be to build this model.
Pros
- Very fast assembly using screw together technology.
- Great performance, both high speed and low speed, with flaps
- Fully sprung, rigidly mounted landing gear works great on short grass
- No cheater holes
- Highly visible paint scheme
- All metal gear servos are installed
- All ball link style push rods are installed
Cons
- Despite references in the Horizon Hobby web pages, there is no"Reflex" stabilization unit installed.
- After contacting Horizon Hobby, they informed me that all units now shipped, will contain the Reflex unit. Up until now (Mar 2022) the units were not included.
Modifications
Here is a video from RC Informer on how to install an 8S power system. Includes a new EDF,and ESC.
Please note that the standard set-up is perfect, and it does puzzle me why some people always want more power!
Review Notes
- Here is a link to RC Groups forum that discusses this RC sport jet.
- This review from "Model Aviation" is well worth a read.

Unique Features
The most obvious unique feature, has to be the colour scheme! You either love it or hate it!
One thing about it is this RC airplane should be easy to see!
Development
The 70mm Super Scorpion, by FMS was very popular. It is now discontinued, but this larger version should prove to be, maybe, more in demand.
The 90mm version is, of course, a direct development.
Competition
In this class of 90 mm RC sport jets, 3 competitors can be considered-
